“…The same authors found no aldrin or dieldrin, while in our study these two compounds occurred in 15% and 50% of the samples, respectively (Table 3). Rovedatti et al (2001) reported no aldrin, dieldrin, or endrin in the surface water of the Reconquista River (Argentina), but higher concentrations of HCH isomers and heptachlor than detected in our study. In the Jarama River (Spain), concentrations of HCH isomers were one order of magnitude lower than in the Oder River, but concentrations of the other pesticides were higher (Fernández et al 2000).…”

Tomza-Marciniak A., Witczak A. 2010. Distribution of endocrine-disrupting pesticides in water and fish from the Oder River, Poland. Acta Ichthyol. Piscat. 40 (1): 1-9.Background. Organochlorine pesticides (OCPs), which act in a similar way to natural hormones, lead to disorders of the endocrine system in animals and humans (endocrine disruptors). Among food products, fish are considered to be the main source of these compounds in the human diet, posing a health risk to consumers. The aim of this study was to determine concentrations in fish and their environment of certain organochlorine pesticides in fish and their environment and to estimate daily intakes (EDI) of individual pesticides from the fish examined. Materials and Methods. Analyses aimed at detecting the pesticides (OCPs: α-, β-, γ-HCH, heptachlor, heptachlor epoxide, aldrin, dieldrin, and endrin) included samples of water taken from the lower stretch of the Oder River and three fish species, which are commonly harvested in that area. Quantitative analyses were carried out using the Capillary Gas Chromatography/Mass Spectrometry method in a GC MSD HP 6890/5973 apparatus.Results. The study found that concentrations of OCPs in fish gonads were significantly higher than in the muscle tissue. The dominant pesticide compound in gonads of roach and bream was γ-HCH, whilst β-HCH predominated in the muscle tissues of those fishes. Endrin, on the other hand was the major pesticide in the muscle tissue of ide. Mean concentrations of OCPs in the gonads ranged from 0.385 to 0.544 ng · g -1 wet weight (w.w.) for α-HCH, 0.745 to 0.832 ng · g -1 w.w. for γ-HCH, 0.479 to 0.576 ng · g -1 w.w. for dieldrin, and 0.381 to 0.684 ng · g -1 w.w. for endrin. Concentrations of the studied compounds in the water taken from the Oder River followed the order: endrin > γ-HCH > α-HCH > dieldrin > β-HCH > heptachlor ≈ aldrin > heptachlor epoxide. The highest log BCF was obtained for fish gonads and ranged from 1.5 (endrin) to 3.4 (heptachlor epoxide). Estimated daily intakes (EDI) varied from 0.0014% to 0.097% of the acceptable daily intake (ADI). Conclusion. This study revealed no direct risk linked to the consumption of fish captured from the study area. However, from the ecological aspect, the accumulation of organochlorine residues in fish gonads has been considered a dangerous phenomenon, as this may result in decreased reproduction of fish and other aquatic organisms, potentially leading to their extinction.

“…There were no records of fish or amphibian kills in the streams at the time of the study. However, simultaneous exposure to multiple contaminants is known to produce an additive, and sometimes even synergistic and complex effects in organisms which can affect the abundance and diversity of non-target species and alter trophic interactions (Rovedatti et al, 2001). Sediment is an important reservoir of contaminants, acting as both an ultimate sink and potential source via a series of biogeochemical processes (Guo et al, 2009).…”
