“…According to the available literature, the residues of some organochlorine pesticides and PCB congeners in tissues of freshwater fish are still found in many countries (4,5,8,12,17,24). Assessing our results obtained for DDTs and PCBs in fish species of cyprinids (without fish from the Vistula River/Cracow), it should be noted that the mean concentrations of these compounds are similar to the results obtained by other authors for the same fish species, or sometimes even lower (10,18,19).…”

The occurrence and concentrations of organochlorine pesticides and polychlorinated biphenyls (PCBs) were determined in 158 muscle samples of bream (Abramis brama) and roach (Rutilus rutilus), and 84 samples of sediments collected from 10 river and lake sampling sites in 2011 and 2012. The concentrations of DDTs (p,p'-DDT, o,p'-DDT, p,p'-DDE, and p,p'-DDD), HCH isomers (-, -, and -HCH), HCB, and PCBs (six indicator PCB congeners 28, 52, 101, 138, 153 and 180) were determined using the capillary gas chromatography. The mean concentrations of DDTs in bream and roach were in the range of 11.2-654 and 4.5-121 µg/kg wet weight respectively, and PCBs were in the range of 1.3-75.9 and 1.1-112 µg/kg wet weight, respectively. Mean concentrations of DDTs and PCBs in sediments were 0.5-270 µg/kg dry weight and <0.1-2.2 µg/kg dry weight respectively. The study showed clear spatial differences in the levels of organochlorine pesticides and PCBs in fish and sediments from different aquatic ecosystems. The highest levels of contaminants were detected in fish and sediments from the Vistula River in vicinity of Cracow. The possible risk to the fish meat consumers and ecological risk were evaluated.

“…Despite their ban in the late 1970s, PCBs continue to be recorded as one of the major contaminants worldwide due to their properties and release from atmospheric deposition, surface runoff from industrial wastewater discharge, and from municipal waste sites in the environment (Lana et al, 2008). Aquatic sediments contaminated by PCBs may pose potential risks to fish, and in turn to humans and wildlife that consume fish (Sorell and McEvoy, 2013).…”

The distribution and concentrations of 6 indicator polychlorinated biphenyl (PCB) congeners, nos. 28, 52, 101, 138, 153 and 180, were determined in surface sediments from the North End Lake in Port Elizabeth, South Africa. Forty-two surficial sediment samples were collected from different locations covering the region that receives the majority of the industrial waste, urban effluents and runoff and thus expected to be contaminated with different degrees of contamination. The analysis was achieved by gas chromatography-mass spectrometry (GC/MS) using the internal standard method. The total PCB concentrations in the samples ranged from 1.60 to 3.06 ng·g -1 dry weight (dw). The concentrations of congener profiles showed significant differences. Generally, the highest PCB concentrations were associated with high organic matter contents and small grain size. The highly chlorinated PCBs dominated with regards to the levels in sediments. PCB 138 was the major contributor to the total PCBs and was detected at 100% of sites. This study provided a snapshot of the PCB contamination status in the North End Lake sediments, and allowed for a comparison between the investigated system and other systems worldwide.

“…PCBs are a group of chlorinated hydrocarbons widely used in industry with many different applications. However, their physical and chemical stability and also their lipophilic character make them serious environmental pollutants, which are highly persistent and tend to accumulate in soils, sediments, tissues and aquatic biota (Lana et al 2008;Eqani et al 2011). OCPs are organic compounds that to a varying degree resist photolytic, biological and chemical degradation.…”

The purpose of this study was to assess selected potentially toxic elements and persistent organic pollutants concentrations in the Shahid Rajaei Dam reservoir as well as their accumulation in barbel and Leuciscus cephalus fish species. The concentration of arsenic, mercury, nickel, chromium and cadmium in all water samples is less than WHO drinking water standard. Chromium shows a higher concentration than WHO standard in both fish species, while nickel and mercury content in barbel fish is higher than WHO standard. The result of principle component analyses indicates an increased elemental concentration due to application of phosphorus fertilizers in the agricultural lands, especially paddy field, ending up to the Tajan River and Shahid Rajaei Dam reservoir. Ni, Co, Mn, Pb and Cr display a quasi-independent behavior within the groups (PC1, PC2 and PC3) reflecting contribution of both geogenic and anthropogenic sources. The concentrations of persistent organic pollutants in all water samples, except M-5 sample, are less than WHO and EPA drinking water standards, while persistent organic pollutants (detected in both fish species) indicate higher contents than those of EPA standard values. Based on carcinogenic health risk value, maximum allowable fish consumption for arsenic is two meals per month. The result of noncarcinogenic health risk of mercury indicates one and three meals consumption per month for barbel and L. cephalus fishes, respectively. The calculation of maximum allowable fish consumption based on carcinogenic health for dieldrin, P HCH, heptachlor epoxide, P DDT and P PCBs reveals monthly meals limitation of both fish species grown in Shahid Rajaei Dam.
