AB  - Artificial sweeteners have been recognized as high-priority emerging contaminants that cause great concern due to unknown environmental behavior and long-term ecotoxicological impact on water resources. Wastewater treatment plants are not designed to remove these pollutants and consequently they are continuously introduced into the aquatic environment. This paper describes investigation of four artificial sweeteners, highly abundant in urban wastewater, and their removal rate in wastewater treatment plants in Serbia, in order to assess the efficiency of the treatment to reduce their environmental inputs. For this purpose, influent and effluent wastewater samples from two treatment plants were extracted and analyzed using liquid chromatography–tandem mass spectrometry.

S obzirom na to da Beograd ne poseduje postrojenje za preradu otpadnih voda, visoki nivoi detektovanog ciklamata ukazuju na kontinualnu kontaminaciju vodenih ekosistema u Republici Srbiji i potencijalnu opasnost po živi svet u vodi.
AB  - Artificial sweeteners are synthetic substances that are used to achieve the sweet taste of
food products, and their application in the Republic of Serbia is regulated by the national
guidelines on food additives. After ingestion, the largest percentage of these compounds passes
unchanged through the human body and reaches the environment through municipal wastewater. In
the last decade, studies have shown the widespread use of artificial sweeteners in surface and
groundwater. Due to limited data on their toxicity to wildlife in the water, as well as on their
behaviour in aquatic ecosystems, they are classified as emerging contaminants.
This paper describes the analysis of widely used sweetener cyclamate by liquid chromatography
with tandem mass spectrometry in untreated urban wastewater of Belgrade to assess the presence
and input of this compound into the environment. The results obtained by analysing four
wastewater samples from different sewage channels in Belgrade show the presence of cyclamate in
the concentration range of 4.3 µg L
–1
–23.2 µg L–1
. Since Belgrade does not have a wastewater
treatment plant, high levels of cyclamate indicate the continuous contamination of aquatic
ecosystems in Serbia and the potential danger to wildlife in the water.

AB  - Artificial sweeteners are known as emerging pollutants in the environment. For decades
they have been used as food and pharmaceutical additives, which is why they are
widespread in natural waters, due to incomplete wastewater treatment. However, some
sweeteners, such as neotame, possess a high sorption affinity and partition to sediment in
the water-sediment system. Therefore, in this paper, a method for the sediment sample
preparation using an ultrasonic extraction for determination of neotame traces was
developed and optimized. After pre-treatment, river sediments (2 g) were extracted using
dichloromethane (3  5 cm3
) in an ultrasonic bath for 3  5 min. The obtained extracts were
analyzed by liquid chromatography with tandem mass spectrometry. The developed
method was applied to sediment samples from several rivers in Serbia – the Tisza, the

sediments in Serbia with artificial sweetener neotame (in the concentration range from 2
