abstract = "The surface sediments sampled from forty sampling sites in the Boka Kotorska Bay, starting from
October 2005 to December 2019, were analysed for the content of ten heavy metals (As, Cd, Cr,
Cu, Hg, Mn, Ni, Pb, Zn, Fe). Five complex indices (pollution load index (PLI), potential ecological
risk index (RI), mean ERM quotient (MERMQ), toxic risk index (TRI), contamination severity
index (CSI)) were determined for each site in the study period (2005, 2007, 2013, 2019), and
statistically examined by principal component analysis (PCA) and cluster analysis (CA). In the
semi-enclosed Bay, which consists of four smaller bays (Kotor, Risan, Tivat, Herceg Novi bays), a
spatio-temporal comparison of sediment quality was carried out using PCA and CA analysis of the
considered pollution indices. Statistical results revealed that the increased environmental risk in
2005 was observed in the bay of Kotor; in 2007 was in the bay of Tivat and Risan; in 2013 in the
bay of Kotor and Tivat; and in 2019 was in the bay of Tivat, particularly at the shipyard site Bijela.
The PCA and CA analysis highlighted that the sediment contamination in Kotor bay decreased from
2005 to 2019, while at the same time increased in Tivat bay, which is an indication of pollution due
to urbanization and population growth in this part of the Bay. The results gave a statistical overview
of the similarities between the pollution indices and the differences in the degree of sediment
pollution in the Bay during the last two decades.",
