“…Considering all the mean OCP concentrations calculated for fish from the RDPD, dieldrin, a-HCH and endosulfan had the highest concentrations (> 200 lg kg With the exception of endosulfan, a similar combination of the most prevalent OCPs detected per impoundment i.e. mainly DDTs and/or dieldrin and/or HCHs, were found in related studies on different fish species in China (Wang et al, 2013), the Baltic Sea (Szlinder-Richert et al, 2008), Turkey (Kalyoncu et al, 2009), Greece (Christoforidis et al, 2008) and the USA (Johnson and Friese, 2013) respectively. Environmental contamination of these chemicals seems to be a global problem.…”

HighlightsClarias gariepinus muscle tissue bio-accumulated organochlorine pesticides. Predicted risk of developing cancer is higher than the recommended safe value of 1. The Roodeplaat Dam risk is as a result of muscle levels of dieldrin and aldrin. Non-carcinogenic risks were 2 to 6 times that of the level considered to be safe. Keywords:Muscle tissue, Organo-chlorine pesticides Human health, Cancer risk, Toxic risk, Fish consumption AbstractThere are increasing concerns regarding the safe human consumption of fish from polluted, freshwater impoundments. The aim of this study was to analyse the muscle tissue of the sharptooth catfish Clarias gariepinus for selected organo-chlorine pesticides (OCPs) and to perform a human health risk assessment using a standard protocol described by the United States Environmental Protection Agency (US EPA). Fish were collected from the polluted Roodeplaat-(RDPD), Rietvlei-(RVD) and Hartbeespoort (HBPD) Dam impoundments located in the north-eastern regions of South Africa. GC-MS analyses showed levels of various OCPs in fish muscle samples from all three impoundments. For fish collected from the RDPD, p,p 0 -DDE, endosulfan, lindane and band d-HCH were the most prevalent OCPs detected, while p,p 0 -DDE and endosulfan were the most predominant in fish from the RVD. Lindane and b-and d-HCH were the main OCPs detected in fish from the HBPD. Dieldrin was the only OCP detected at concentrations for which a cancer risk and a hazard index above the acceptable risk levels were estimated. This was the case for fish from both the RDPD and RVD impoundments. No toxic risk was estimated should fish from the HBPD be consumed.

We examined the relationship between muscle and scale mercury (Hg) and lead (Pb) concentrations in chub Squalius cephalus L. from six riverine sites in the Czech Republic in order to determine whether scale analysis alone could provide a nonlethal and convenient method for prediction of heavy metal concentration in muscle tissue. Our results confirm tissue-specific heavy metal accumulation in chub, with Hg tending to accumulate primarily in muscle tissue and Pb in scales. We found no significant relationship, however, for concentrations of either Pb or Hg between muscle tissue and scales of chub. Our results indicate that scales cannot be used for predicting heavy metal contamination in muscle of chub and we recommend, therefore, that muscle biopsy methods continue as the preferred method of analysis.

“…Por estas razões, a concentração desses compostos em peixes é, com frequência, milhares ou milhões de vezes maior que a concentração dissolvida em água. [151][152][153] A poluição dos ambientes aquáticos não é meramente uma questão da concentração do poluente que se encontra somente no estado dissolvido, pois nota-se que os pequenos valores de solubilidade dos organoclorados em água podem ser enganosos, haja vista que esses compostos estão localizados, em maiores concentrações, em fontes diferentes do meio aquoso. Como a maioria dos compostos organoclorados, no meio ambiente o HCB é mais solúvel em meios orgânicos naturais que em águas.…”

This paper describes the use of pesticides in agriculture. Research has shown that significant quantities of pesticide residues have been found in many types of foods. Thus, an overview is given of pesticide residue determinations in fruits and vegetables, with special attention to apples. The toxicity and the adverse effects possibly caused by the exposure of these compounds are alerting the scientific community to develop studies about the validation of analytical methods for multiresidue pesticide determination in these samples. This review shows that pesticide-residue determination in apples is becoming a very important and challenging issue.
