“…In the reproductive phase, when eggs are produced, lipids are mobilized from the liver and mainly from the muscle to the gonads (Castell et al 1972). The most frequently analyzed tissues to verify contamination by OCPs in sh are usually muscle, liver and gills (Corrêa et al 2022;Rohani 2023). Few studies evaluate the presence of OCPs in roes.…”

The Alagados reservoir is located in one of the main grain-producing and exporting areas in Brazil. Additionally, it is situated beneath the Guarani Aquifer, one of the largest aquifers in the world, which is an important source of groundwater for several countries in South America. Residues of organochlorine pesticides (OCPs) were detected in roe, viscera, and muscle of Astyanax altiparanae from the Alagados reservoir (Paraná State, Brazil) by GC/ECD. The detected OCPs include Aldrin (17.1 to 50.6 µg/Kg), α-endosulfan (3.4 to 23.5 µg/Kg), p,p’-DDE (4.2 to 134.7 µg/Kg), Dieldrin (84.7 to 183.1 µg/Kg), β-endosulfan (6.0 to 51.6 µg/Kg), and p,p’-DDT (56.6 to 286.8 µg/Kg) in roe; Aldrin (19.8 to 93.3 µg/Kg), α-endosulfan (8.3 to 37 µg/Kg), p,p’-DDE (83.5 to 209.2 µg/Kg), Dieldrin (18.0 to 193.5 µg/Kg), β-endosulfan (21.0 to 95.4 µg/Kg), and p,p’-DDT (52.3 to 89.2 µg/Kg) in viscera; and Aldrin (8.28 to 26.16 µg/Kg), α-endosulfan (4.16 to 12.3 µg/Kg), p,p’-DDE (12.7 to 40.17 µg/Kg), Dieldrin (45.6 µg/Kg), β-endosulfan (8.58 to 58.54 µg/Kg), and p,p’-DDT (12.0 to 23.1 µg/Kg) in muscle. Principal component analysis showed a proportional relationship between the highest concentrations of OCPs and the width of the fish abdomen. The levels of OCPs detected in Astyanax altiparanae samples did not exceed the maximum residue limits imposed by the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO). However, risk quotient calculations indicated possible health risks associated with the consumption of these fish.

“…Terefore, understanding uptake, behavior and response of toxicant in fsh may have a high ecological signifcance [10]. At present, using fsh as a bioindicator of chemical pollutants has been a common procedure in several countries worldwide like China, Brazil, Argentina, the Atlantic Ocean, and other regions [11][12][13][14].…”

This study used gas chromatograph-mass spectrometer (GC-MS) to determine three kinds of halogenated organic pollutants (HOPs) in the edible muscles of nine fish species in the Laibin section of the Hongshui River of Xijiang River in the Pearl River system. The results showed that the sum of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) in fish muscle was 8.94∼43.32 ng/g ww, 1.22∼4.09 ng/g ww, and ND∼0.13 ng/g ww, respectively. Evaluation indicators include analysis of the composition of homologous compounds, residues in different diets and habitats, and estimated daily intake (EDI) calculations. The analysis of the composition characteristics of homologous compounds showed that endrin was the most dominant in OCPs; hexachlorobenzene was the most dominant in PCBs; and BDE 154 was the most dominant PBDEs. Calculations of the levels of the HOPs in fish of different diets and habitats showed that OCPs and PCBs had the highest residues in carnivorous fish, and PBDEs had the highest residues in herbivorous fish. The residual OCPs, PCBs, and PBDEs in demersal fishes were the most. The estimated daily intake (EDI) results showed that daily fish consumption in the Laibin section of the Hongshui River would not cause HOPs health risks to the local residents. However, there is still a need for continuous monitoring of HOPs to reduce pollutant emissions and prevent pollution conditions from arising.
