Organochlorine and organobromine compounds in a benthic fish (Solea solea) from Bizerte Lagoon (northern Tunisia): Implications for human exposure

Chlorinated compounds in the muscle tissue of fish from the Croatian Adriatic: preliminary data on contamination and the associated health risks / Klorirani spojevi u mišićnom tkivu riba iz istočnog Jadranskog mora: preliminarni podaci o zagađenosti i zdravstvenim rizicima

“…The obtained trend of the DDT isomers (DDE>DDT≈DDD) is consistent with the high chemical stability and long half-life of DDE in the aquatic environment in comparison to the parent DDT (25). The DDTs levels found in this study are similar to recent reports for different fish species from the Ionian Sea (29), Gulf of Naples (25), Marmara Sea (30), and Atlantic coastal regions (27) and are higher than those reported for other coastal areas of the Mediterranean (26,(31)(32)(33) (Table 3).…”

“…The share of OCPs was lower, ranging from 0.01 % for HCB to 28.2 % for DDTs (lw). This order of the m a i n g r o u p s o f o r g a n i c c o n t a m i n a n t s (PCBs>DDTs>HCHs>HCB) in fish from Croatian waters is in agreement with other reports for different fish species and different Mediterranean and Atlantic coastal regions (25)(26)(27).…”

“…The HCH pattern (β-HCH>γ-HCH≈α-HCH) is consistent with our previous report on HCH patterns in mussels from the Croatian coast (34). Mass fractions of ΣHCHs in this study are similar to the values recorded for Orbetello Lagoon (33), the Marmara Sea (30), and Atlantic coastal regions (27) and higher than the values reported for the Tunisian coastal area (26) and the Black Sea (32) ( Table 3).…”

“…The dominance of PCB-153, PCB-138, and PCB-118 is in agreement with other reports on marine organisms from the Adriatic (9,25,28,29,31,35), reflecting their high lipophilicity, stability, and persistence, which favour accumulation in aquatic animals. The overall levels are consistent with those recently found in fish species from the Adriatic Sea (13,15,29) and Atlantic coastal regions (27), and are higher than the values for the Black Sea (32), Catalan coast (31), Tunis (26), and Orbetello Lagoon (33) ( Table 3).…”

“…The DDE/DDT ratios are often used as an indicator of recent DDT input into the environment. The prevalence of p,p'-DDE in this study (DDE/DDT>0.6 in more than 91 % of samples) is in line with the reports on DDT metabolites in fish species from other European and Mediterranean countries (24)(25)(26)(28)(29)(30)(31), and indicates that DDT in our study is mostly owed to historical use or remote sources and that it has not recently been used in agriculture. The obtained trend of the DDT isomers (DDE>DDT≈DDD) is consistent with the high chemical stability and long half-life of DDE in the aquatic environment in comparison to the parent DDT (25).…”
