“…The discrepancy could be attributed to the different species investigated in Lake Apopka as the previous study measured p, p’ -DDD in brown bullheads and catfish which are bottom feeder as compared to bass that feed above the bottom and/or p, p’ -DDD has been further metabolized, but p, p’ -DDE is persistent. The tissue distribution of OCPs in Lake Apopka LMB reported here are, however, similar to results from other water bodies, which showed the highest OCP residues on a ww basis in the brain of wild-caught rainbow trout (Sahagun et al, 1997) and silver carp (Zhou et al, 2007). …”

“…In addition, understanding the distribution pattern of OCPs in other tissues (e.g., liver, kidney, gonad, brain, and spleen) provides insight into pathways of OCP bioaccumulation and helps define primary exposure in exposed animals and resultant human exposures from given levels of environmental contamination. OCP concentrations are normally found to be the lowest in muscle tissues but the highest in either hepatobiliary-related tissues such as liver, bile, and heart (Guo et al, 2008; Zhao et al, 2013, 2014) or brain (Sahagun et al, 1997; Zhou et al, 2007). These results have been primarily observed in studies where fish are chronically exposed to contaminants resulting in uptake of contaminants by different tissues in proportion to their lipid content at equilibrium.…”

Tissue concentrations of persistent organochlorine pesticides in laboratory-exposed largemouth bass (Micropterus salmoides) and in bass collected from Lake Apopka, FL were determined by both total mass and lipid normalized mass to better understand the bioaccumulation pathways of contaminants. In the laboratory study, male bass were orally administered a single dose of a mixture of two pesticides (p, p’-dichlorodiphenyldichloroethylene (p, p’-DDE) and dieldrin) and then fed uncontaminated food for 28 days. Gastrointestinal tract, liver, brain, gonad, kidney, spleen, and muscle were collected for chemical analysis. Different profiles were observed by total mass in tissues compared to lipid normalized mass. On a lipid normalized basis, p, p’-DDE was highest in the gastrointestinal tract followed by the liver, gonad, spleen, muscle, kidney and then brain. Dieldrin, on the other hand, was highest in the gastrointestinal tract and spleen and then followed by the gonad, muscle, liver, kidney and brain. Distribution of the chemicals to the organs differed by their log KOW and generally followed the blood flow path after the gastrointestinal tract. The low levels in kidney and brain suggest insufficient time for equilibration into these tissues, especially into the brain where the blood-brain barrier may be slow to traverse. In Lake Apopka fish, dichlorodiphenyltrichloroethanes (DDXs, sum of p, p’-DDE, p, p’-DDD, and p, p’-DDT), Drins (sum of aldrin, dieldrin, and endrin), and hexachlorocyclohexanes (HCHs) were found. For DDXs, the lipid normalized concentrations in each tissue were about the same, as predicted from theory. For Drins and HCHs, the lipid normalized concentrations were similar for kidney, spleen, brain, gonad and muscle, but much lower in the gastrointestinal tract and liver, probably because of metabolism occurring in those tissues.

“…Several reports are available on pesticide residue analyses in various fish. Some of these reports explain the anti-steroidogenic nature of these toxicants and also show that these pollutants act as endocrine disruptors (Hilmy et al 1983a, b;Verma, 1991;Singh et al 1994; Kime and Singh 1996;Sahagun et al 1998;Singh and Canario 2004;Harding et al 2006; Barse et al 2007). Bioaccumulation of insecticide residues in Ganges river dolphins (Kannan et al 1994;Senthilkumar et al 1999a;Kumari et al 2002) and fish as well as in foodstuffs (Tanabe et al 1991;Kannan et al 1995) has also been reported.…”

This investigation was performed to monitor hexachlorocyclohexane isomers (HCHs), dichlorodiphenyltrichloroethane (DDT, and its metabolites, refered to as DDTs), plasma levels of estradiol-17beta (E2), and the gonadosomatic index (GSI) between sampling sites of unpolluted ponds of Gujartal, Jaunpur (control site) and the polluted rivers Gomti (Jaunpur) and Ganga (Varanasi), which affect the reproductive physiology of some edible catfish and carp during the pre-monsoon season. HCHs and DDTs were measured by gas liquid chromatography (GLC) and hormones by radioimmunoassay (RIA). The results indicated that the level of HCHs and DDTs was very high in both the catfish and the carp captured from the polluted rivers compared with the fish captured from the control site. The GSI and E2 values were lower in both groups of fish when compared to the fish from the control site. The results also indicate that catfish showed greater bioaccumulation of HCHs and DDTs than carp, above the permissible limit, as compared to the fish from the control site. In conclusion, fish from the Gomti and Ganga rivers were highly polluted when compared with fish from the control site, as was evident from high levels of tissue bioaccumulation of HCHs and DDTs and decreased levels of plasma E2, inhibiting the reproductive physiology of these species at the receptor level. The levels exceeded the maximum residue limits (MRL) as recommended by Codex, hence it is suggested that the fish should be avoided for food purposes.

“…This class of organic compounds constitutes one of the groups of contaminants of most concern from a food safety perspective. Environmental contamination by persistent OC pesticide residues has been widely documented in several countries in fish (Sahagú n et al 1998;Doong et al 1999;Borgä et al 2001;Pandit et al 2001). Such residues persist in the human body as a consequence of ingestion from food over many decades, are endocrine disruptors, cause immune suppression and inhibit various enzymes, and can lead to higher susceptibilility to the onset of cancer (Cruz et al 2003).…”

This paper reports the results for the surveillance of nine organochlorine pesticides (HCH isomers (alpha, beta, e, gamma), p,p'-DDD, p,p'-DDT, p,p'-DDE, p,p'-DDD, HCB and aldrin) in muscle of three fish species, European pilchard (Sardina pilchardus), Atlantic horse mackerel (Trachurus trachurus) and Atlantic mackerel (Scomber scombrus). Analytical methodology included n-hexane extraction, clean-up with 2% deactivated Florisil, and quantification with gas chromatography-electron capture detection (GC-ECD). The highest mean concentrations were found for p,p'-DDT in sardine and mackerel at levels of 30.1 and 109.9 microg kg(-1), respectively, and for p,p'-DDD in horse mackerel at 51.9 microg kg(-1). Three species had higher levels for S-DDT than S-HCH. The estimated daily intake of organochlorine pesticides in the three species showed that in sardine, the highest EDIs were found for aldrin, at 1.8 ng kg(-1) bw day(-1), which represents 1.8% of the acceptable daily intake (ADI), and for ss-HCH, at 4.0 ng kg(-1) bw day(-1), representing 0.4% of ADI. Lowest values were found for Atlantic mackerel. Statistical analysis to determine the differences in mean concentrations of pesticides between species, and any correlation between groups of residues related with each one of the species, was undertaken.
