AB  - The occurrence and distribution of yttrium and rare earth elements (REYs), along with major elements and heavy metal(loid)s (HMs) in coal fly ash (CFA) from five coal-fired power plants (CFPPs), were analyzed, and the REY-associated ecological and health risks were assessed. The individual REYs in CFA were abundant in the following order: Ce > La > Nd > Y > Pr > Gd > Sm > Dy > Er > Yb > Eu > Ho > Tb > Tm > Lu. The total REY content ranged from 135 to 362 mg/kg, averaging 302 mg/kg. The mean light-to-heavy REY ratio was 4.1, indicating prevalent light REY enrichment in CFA. Significantly positive correlations between the REYs suggested that they coexist and share similar origins in CFA. REYs were estimated to pose low to moderate ecological risks, with risk index (RI) values ranging from 66 to 245. The hazard index (HI) and target cancer risk (TCR) of REYs from CFA, estimated to be higher for children (HIc = 0.15, TCRc = 8.4 × 10−16) than for adults (HIa = 0.017, TCRa = 3.6 × 10−16), were well below the safety limits (HI = 1, TCR = 1.0 × 10−6). However, the danger to human health posed by HMs in the same CFA samples (HIc = 5.74, TCRc = 2.6 × 10−4, TCRa = 1.1 × 10−4) exceeded the safe thresholds (excl. HIa = 0.63). The mean RI and HI attributed to REYs in CFA were 14% and 2.6%, respectively, of the total risks that include HMs.

AB  - Molecularly imprinted polymers (MIPs) as materials with determined levels of selectivity and specificity for designated analytes have recently gained much attention in various application fields. However, with the growing adoption of green analytical chemistry (GAC) principles, it is essential to investigate the greenness of MIP synthesis and its subsequent application in sample preparation, as well as to evaluate the "green"nature of the developed analytical methodologies, such as dispersive solid-phase microextraction (DSPME). Accordingly, the main objective of this research was to evaluate the greenness of MIP-based glycidyl methacrylate synthesis and MIP use as a DSPME sorbent prior to high-performance liquid chromatography with mass spectrometry (HPLC-MS). The green perspective of MIP-DSPME prior to HPLC-MS was investigated using various analytical metric tools such as the Analytical Eco-Scale, the Green Analytical Procedure Index, and Analytical GREEnness (AGREE). Since these analytical tools are not fully implementable for the assessment of the greenness of the MIP synthesis, some alternative approaches were used to optimize the synthesis parameters to make the MIP DSPME sorbent as close as possible to the GAC principles. The calculated AGREE score (0.62) and 91 points in the Analytical Eco-Scale for the proposed DSPME technique using MIP indicated a high level of greenness.

AB  - Conventional wastewater treatment processes are increasingly difficult to fulfill strict standards of
achieving the required quality. Therefore, it is necessary to apply processes that in an efficient and
economically justified way reach the necessary limits in order to discharge wastewater into the
recipient. The process of photolysis represents the degradation of the starting pollutant practically to
water and carbon dioxide. The whole process takes place under the action of a UV lamp that imitated
solar irradiation. The process is environmentally justified since, unlike some other advanced
oxidation processes - AOPs, there is no use of additional, hazardous, chemicals which possibly results
in the precipitates formation that are leading to further treatment. In this paper, photolytic degradation
of pesticide thiophanate methyl was performed in doubled wall quartz reactor equipped with a
thermoregulation system. Reaction was forced under Osram ULTRA VITALUX UV lamp (300W).
Kinetics of photodecomposition process was followed by pseudo-first order. In certain time periods,
specimens were sampled, filtered and monitored by UV spectrophotometer Shimadzu 1800 with an
aim to determine the concentration of xenobiotic. Complete degradation of present xenobiotics was
obtained after 240 min. With an aim to enhance the degradation process, hydrogen peroxide was
added as a boosting agent which cause a shortening in demanded time (150 min) for complete
degradation. Verification of the success of decomposition was confirmed by the obtained values of
chemical oxygen demand (COD), which reveal that the established system has a basis for real
application in industrial or municipal wastewater.

AB  - Fly ash is a by-product of coal combustion in thermal power plants. Heavy metal(loid)s
(HMs) are the most recognized among the many dangerous compounds in fly ash. These substances
may contaminate the environment and can pose a threat to human health. Various analytical
techniques are used to analyze HMs in leachate. To investigate the possibility of contamination of
the environment, heavy metals and metalloids (Pb, Zn, Mn, Fe, As, Ba, Be, Cu, Cr, Co, Cd, Sb, Se,
and V) were leached from fly ash using a toxicity characteristic leaching procedure (TCLP). The fly
ash samples used in this work were obtained from four thermal power plants (Kostolac, Kolubara,
Tent B, and Morava). Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)
technique was used to determine the concentration of these elements in the leachate. Accurate
elemental analysis was achieved with this technique. Among all analyzed metal(loid)s, Fe, Mn, Zn,
and As were the most abundant.

AB  - Potentially toxic elements (PTEs) are transferred to vegetables primarily through
agricultural soil or irrigation water. PTEs in agricultural soil originate from pedogenic and
anthropogenic sources. In most cases, soil contamination with these elements happens via river
systems or air pollution. Furthermore, food is now imported from many regions and countries, where
it is grown in various conditions and on various agricultural lands. Peppers (Capsicum annuum) are
popular vegetables in Serbia and worldwide. They are consumed in numerous dishes as fresh fruits,
spices, or ingredients. Peppers are reach source of carotenoids, vitamins, antioxidant compounds,

present in fresh, dried, and processed peppers obtained from the Serbian market. The exposure
assessment was conducted for people in four regions of Serbia by calculating the target hazard
quotient (THQ) and carcinogenic risk (CR). The comparison across areas was made due to
significant disparities in pepper consumption between them.

AB  - Dispersive liquid–liquid microextraction (DLLME) using a floating organic drop has been optimized and used for the sample preparation of four commonly used ultraviolet filter (UVF) substances in sunscreens. Plackett–Burman experimental design was used to screen 10 variables in DLLME. The most significant variables were then optimized by using a response surface method with a Box–Behnken design. DLLME followed by an optimized HPLC identified octocrylene, 2-ethylhexyl-4-methoxycinnamate, ethylhexyl salicylate, and homosalate as the frequently found UVFs in commercial sunscreens. The systemic exposure dosage and margin of safety (MoS) for the identified UVFs were estimated using in-use concentrations and application patterns. The average systemic exposure dosage values for octocrylene, 2-ethylhexyl-4-methoxycinnamate, ethylhexyl salicylate, and homosalate were 0.52, 0.61, 0.020, and 0.079 mg/kg body weight per day, respectively. Whereas the average MoS values for individual UVFs ranging from 296 to 3160 were all significantly higher than the limit value of 100, the combined exposure risks were slightly above the limit. The probabilistic health risk assessment using Monte Carlo simulation revealed that the combined MoS values were (mean, 10‰, 90‰) 342, 119, and 441, respectively. Regarding the usage of sunscreen cosmetics containing the UVFs studied, these results indicate a safety concern for those who apply multiple UVF products.

The probabilistic health risk assessment using Monte Carlo simulation revealed that the combined MoS values were (mean, 10‰, 90‰) 342, 119, and 441, respectively. Regarding the usage of sunscreen cosmetics containing the UVFs studied, these results indicate a safety concern for those who apply multiple UVF products.",

AB  - A fast and straightforward reversed-phase dispersive liquid–liquid microextraction (RP-DLLME) using a deep eutectic solvent (DES) procedure to determine free tryptophan in vegetable oils was developed. The influence of eight variables affecting the RP-DLLME efficiency has been studied by a multivariate approach. A Plackett–Burman design for screening the most influential variables followed by a central composite response surface methodology led to an optimum RP-DLLME setup for a 1 g oil sample: 9 mL hexane as the diluting solvent, vortex extraction with 0.45 mL of DES (choline chloride–urea) at 40 ◦C, without addition of salt, and centrifugation at 6000 rpm for 4.0 min. The reconstituted extract was directly injected into a high-performance liquid chromatography (HPLC) system working in the diode array mode. At the studied concentration levels, the obtained method detection limits (MDL) was 11 mg/kg, linearity in matrix-matched standards was R2 ≥ 0.997, relative standard deviations (RSD) was 7.8%, and average recovery was 93%. The combined use of the recently developed DES -based RP-DLLME and HPLC provides an innovative, efficient, cost-effective, and more sustainable method for the extraction and quantification of free tryptophan in oily food matrices. The method was employed to analyze cold-pressed oils from nine vegetables (Brazil nut, almond, cashew, hazelnut, peanut, pumpkin, sesame, sunflower, and walnut) for the first time. The results showed that free tryptophan was present in the range of 11–38 mg/100 g. This article is important for its contributions to the field of food analysis, and for its development of a new and efficient method for the determination of free tryptophan in complex matrices, which has the potential to be applied to other analytes and sample types.

AB  - Isoamyl 4-methoxycinnamate (IAMC) is an organic compound belonging to UV filters, part of
many cosmetic products that aim to protect human skin and hair from harmful solar radiation.
Numerous studies conducted in recent decades have confirmed the presence of IAMC in the
environmental waters and its toxicity to aquatic species. Low concentrations of this compound
in environmental samples require sample preparation that achieves a high enrichment factor.
Solid-phase extraction (SPE) achieves a high efficiency of extraction of organic compounds
and higher enrichment factor compared to liquid-liquid extractions. In this paper, sample
preparation involves the SPE of IAMC using Oasis HLB cartridges. Several experimental
variables, such as pH value and volume of sample, eluent type, eluent volume, and salt content
were considered during the optimization process. The eluted compound was analyzed using
liquid chromatography-tandem mass spectrometry (LC-MS/MS). Based on the recovery data,
the optimal parameters of the SPE method were obtained: extraction from 50 mL of the aqueous
sample without added salt, initial pH of the sample set to 8, and dichloromethane/methanol
mixture used as an organic solvent for elution. The optimized SPE procedure is suitable for the
analysis of IAMC in water. The recovery was 98%, and the enrichment factor was 150.

AB  - Mass use of plastics in the consumer lifestyle has caused a problem that the inventors of these
polymers could not anticipate. Over the last 50 years, world plastic production has doubled.
Plastic particles larger than 2.5 cm in diameter are called macroplastics. The types of
degradation that affect the decay of macroplastics are photodegradation, microbiological and
thermo-oxidative degradation. Macroplastics that are exposed to mentioned external factors
break into smaller pieces that scientists today call microplastics. Microplastics (MPs) are
defined as any piece of plastic with a diameter of 100 nm to 5 mm; particles smaller than 100
nm are called nanoplastics. MPs are all around us, there are in cosmetic products, the fibers of
our clothes, the water we drink, and the food we eat. The recent understanding of MPs as
pollutants present in the environment has become a global concern and has resulted in intensive
research in this area. Knowledge of MPs is limited, but researchers are increasingly examining
their properties and environmental impact. Recent studies have shown that various water
pollutants can be adsorbed on MPs, therefore MPs may also play a role as vectors for harmful
substances.
In this paper, the adsorption of the selected hormones – estrone, 17β-estradiol, 17α-ethinyl
estradiol on low-density polyethylene (LDPE), polyethylene terephthalate (PET), and
polyamide (PA) microplastics are presented. Selected hormones are among the most frequently
detected endocrine-disrupting chemicals in the aquatic environment. It is shown that among
selected estrogens, 17β-estradiol has the highest affinity for binding to MPs.

In this paper, the adsorption of the selected hormones – estrone, 17β-estradiol, 17α-ethinyl
estradiol on low-density polyethylene (LDPE), polyethylene terephthalate (PET), and
polyamide (PA) microplastics are presented. Selected hormones are among the most frequently
detected endocrine-disrupting chemicals in the aquatic environment. It is shown that among
selected estrogens, 17β-estradiol has the highest affinity for binding to MPs.",

AB  - Solid-phase extraction (SPE) of eleven ultraviolet filters (UVFs): benzophenone-1 (BP-1); benzophenone-3 (BP-3); benzophenone-4 (BP-4); isoamyl p-methoxycinnamate (IAMC), homosalate (HMS); 4-hydroxybenzophenone (4-HB); 4-methylbenzylidene camphor (4-MBC); octocrylene (OC); octyl dimethyl-p-aminobenzoate (OD-PABA); 2-ethylhexyl-4-methoxycinnamate (EHMC); and avobenzone (AVO), has been optimized using Plackett-Burman design, Box-Behnken design, and Derrindzer desirability function. Of the six SPE variables studied, the most influencing is the type of eluent followed by pH and the methanol content in the rinsing solvent. A method with good analytical performance was obtained by applying optimal SPE conditions and liquid chromatography-tandem mass spectrometry (LC-MS/MS), with the method detection limit ranging from 0.1 to 5 ng/L, recovery from 44% to 99%, and relative standard deviation (RSD) within 19%. This method was used to analyze the content of UVFs in an urban lake (Sava Lake, Serbia). UVFs occurrence, geostatistical distribution, and associated environmental risk are highly dependent on recreational activities. The average concentrations of UVFs ranged from 0.3 to 113 ng/L, and the most present substance was EHMC, followed by 4-MBC and BP-3. The spatial distribution of the risk quotient (RQ = 0.04–1.7) inside the lake is highly correlated with the number of people bathing and swimming. Human exposure through the dermal pathway is higher than ingestion for most UVFs. Monte Carlo simulation of probabilistic risk assessment estimated the percentile P10, P50, P90 of 12.7; 17.3; 47.5 and 20.1; 27.6; 77.5 ng/kg∙day for total human exposure of adults and children, respectively. The sensitivity analysis revealed that the health risk estimate depends mostly on the content of EHMC, HMS, and 4-MBC, while the most influential exposure variables were human body weight and skin surface area. There is no serious concern to human health due to UVFs in the short term; however, a high ecological risk in some parts of the lake is estimated.

AB  - A core-shell amino-functionalized glycidyl methacrylate magnetic molecularly imprinted polymer (MIP) was synthesized by the suspension polymerization/surface imprinting method and characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), mercury porosimetry, nitrogen gas adsorption–desorption, and elemental analysis. This MIP was used as the sorbent in dispersive solid-phase microextraction (DSPME) of aniline from textile wastewater prior to high-performance liquid chromatography-mass spectrometry (HPLC-MS) measurements. Since aniline is toxic and a probable human carcinogen, its determination in water is of great significance. This is a challenging task because aniline is usually present at trace levels. The effects of different DSPME variables on the preconcentration efficiency have been studied by using the Plackett–Burman screening design of experiments (DoE) followed by response surface methodology optimization using the Box-Behnken design. Thus, DoE enabled the investigation of several variables simultaneously. Under optimized conditions, aniline was effectively and selectively separated by a small amount of the DSPME sorbent and detected in real textile wastewater samples. The method detection limit of 1 ng mL−1 was attained, with good method linearity and acceptable recovery and precision. The results showed that the studied MIP could be a reliable DSPME sorbent for efficiently analyzing trace aniline in real wastewater samples.

AB  - A Plackett-Burman factorial design (PBD) has been used for the optimization of dispersive liquidliquid microextraction (DLLME) of UV filters from water. The experimental procedure included a DLLME
sample preparation prior to high-performance liquid chromatography triple quadrupole mass spectrometry
(HPLC-MS/MS) measurements. The variables of the DLLME process for simultaneous preconcentration of UV
filters (avobenzone and octocrylene) have been studied using PBD with twelve experimental runs. Several
experimental variables including the extractant type, pH value, the disperser type, extractant volume, disperser
volume, vortexing/sonication, centrifugation speed, reconstitution solvent, salt content, temperature, and
centrifugation time were considered in the optimization process. PBD results revealed the most important
variables that affected the extraction efficiency (EF). The first three most influential variables, as showed using
a Pareto graph, were in the following order: the extractant volume > the disperser type > the extraction
temperature. Based on the main effects plot, it was revealed that some variables (pH value, the disperser type,
extractant volume, temperature, centrifugation speed, salt content) increased over the experimental domain,
while the others (the extractant type, disperser volume, vortexing/sonication, centrifugation time, reconstitution
solvent) decreased.

abstract = "A Plackett-Burman factorial design (PBD) has been used for the optimization of dispersive liquidliquid microextraction (DLLME) of UV filters from water. The experimental procedure included a DLLME
sample preparation prior to high-performance liquid chromatography triple quadrupole mass spectrometry
(HPLC-MS/MS) measurements. The variables of the DLLME process for simultaneous preconcentration of UV
filters (avobenzone and octocrylene) have been studied using PBD with twelve experimental runs. Several
experimental variables including the extractant type, pH value, the disperser type, extractant volume, disperser
volume, vortexing/sonication, centrifugation speed, reconstitution solvent, salt content, temperature, and
centrifugation time were considered in the optimization process. PBD results revealed the most important
variables that affected the extraction efficiency (EF). The first three most influential variables, as showed using
a Pareto graph, were in the following order: the extractant volume > the disperser type > the extraction
temperature. Based on the main effects plot, it was revealed that some variables (pH value, the disperser type,
extractant volume, temperature, centrifugation speed, salt content) increased over the experimental domain,
while the others (the extractant type, disperser volume, vortexing/sonication, centrifugation time, reconstitution
solvent) decreased.",

AB  - A particularly high pollution level of total petroleum hydrocarbons (TPH) was observed in
the soil at the railway junction in the city of Niš (Serbia). The TPH level in most of the
studied soil samples exceeded the limit intervention value of 5000 mg/kg. The
contamination level decreased alongside the train rail route, according to the distance from
the fuel station. This suggests the pollutant role of railway transport, with the fuel station
identified as a pollution hotspot. Health risk assessment of the contaminated soil has been
made by using TPH fraction approach. Among six aliphatic and seven aromatic
hydrocarbon fractions, the highest TPH content in soil was measured for EC16-C35
aliphatic fraction. This aliphatic fraction causes the highest individual non-cancerogenic
health risk, while cancerogenic risk is mostly attributed to EC16-21 aromatic fraction. Both
the total non-cancerogenic risk (expressed as a hazard quotient) of 5.8, and cancerogenic
risk (expressed as an incremental excess lifetime cancer risk) of 11.7·104, notably exceed
safety target values of 1.0 and 1.0·10-6, respectively.

AB  - Soil samples from the site of the former largest paint and varnish factory in ex-Yugoslavia were analyzed for arsenic and eight heavy metals (Pb, Cd, Zn, Cr, Ni, Cu, Fe, and Hg). Several additional soil properties (pH, sulfur, nitrogen, phosphorus, and water content) were also measured. Multivariate analysis showed strong correlations between Pb and Zn; and a moderate correlation between Cu and Ni. There was no correlation between heavy metals and any of the analyzed soil properties parameters. A factor analysis grouped most heavy metals, except Cd, which showed different behavior, and Fe and As, which associated with soil properties. The soil samples were clustered into two distinctive groups. Positive matrix factorization receptor modeling clearly identified Zn and Pb as belonging to the traffic vehicle factor. The second factor dominating arsenic was industrial chemical emissions, while the third factor containing most of the heavy metals was attributed to natural background variation. The last non-metallic factor, dominated by sulfur, was the result of past activities in the paint facility. The average enrichment factor values were for the metals analyzed were: 0.73; 0.71; 2.4; 0.58; 2.3; 0.87; 1.6; and 0.76; for Cr, Cd, Pb, Ni, Zn, Cu, As, and Hg, respectively. Only moderate soil enrichment by Pb and Zn was found. The geoaccumulation index values showed a moderately polluted soil with Pb and Zn, but most contributing to the ecological risk were Cd with 63% and Hg with 19%. These two metals are of major concern in this case study due to their high toxicity, even though they are present at very low concentrations. Generally, a moderate ecological risk was estimated for most soil samples, except for a small number of high-risk samples. Spatial distribution mapped three severely polluted sub-areas. In general, the paint and varnish industry moderately contributes to the contamination of soil. The main ecological risk from metal contamination is not related to the paint technological production process itself, but from other activities at the site that deposit of heavy metals into the soil.
