“…The major organic pollutants are polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs), and inorganic one is potentially toxic elements (PTEs). These pollutants are ubiquitous contaminants in different environments (Martin et al 2003;Wu 2005, 2006). Aquatic environments are important biotopes that should be controlled sensitively from unsafe industrial, agricultural and other anthropogenic activities (Mohiuddin et al 2011;Zeng et al 2013;Chakraborty and Owens 2014).…”

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.

“…The actual pollution in the ambient environment around the recycling places should be evaluated for the safety of the local ecosystem. PBDEs, PCBs and PCDD/Fs are recognized as three types of anthropogenic environmental pollutants with high toxicity (Darnerud et al, 2001;Martin et al, 2003). The majority of E-waste is recycled by basic methods, such as manual treatment and open incineration.…”

Polybrominated diphenyl ethers (PBDEs) have been determined in 30 samples, including soil, biota and plant collected from an electronic waste recycling site and its vicinage towns. Polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and dibenzo-furans (PCDD/Fs) were also simultaneously analyzed in 20 samples. PBDEs were detected in all soil samples and the highest was up to 789 ng/g dry weight (dw). The toxic equivalency (TEQ) of PCBs and PCDD/Fs detected in E-waste recycling site is significant higher than those in the vicinage samples. Biota and plant were also contaminated with high level of PBDEs, PCBs and PCDD/Fs in this area. High levels of the three kinds of organic compounds in the environmental samples showed that the E-waste recycling have induced serious environmental problems.

“…Polychlorinated biphenyls (PCBs) were discovered in the early 1900 s. They form a large family of about 209 different ‘congener’ molecules that differ in the number of chlorine atoms (1–10 Cl) (Hutzinger et al 1974 ; Hawker and Connell 1988 ), their locations in the biphenyl core and other spatial properties. From the 1920s onwards, PCBs have found multiple uses, due to their high thermodynamic stability and chemically inert nature (Martin et al 2003 ; Fu and Wu 2006 ; Darko et al 2008 ). However, because of their high stability, environmental PCBs degrade very slowly.…”

This study evaluated the distribution of polychlorinated biphenyls (PCBs) in 39 surface sediment samples and four cores collected in Toulon Bay, a semiclosed area submitted to various anthropogenic inputs. The concentration of PCBs in the superficial sediment samples ranged from 1.7 to 2530 ng g−1 dry weight. The spatial distribution of these compounds suggested that the high concentrations of these contaminants are located in the small bay and are related to human activities. In the larger bay, the concentrations were in the same order of magnitude than those reported in others locations around the world. Comparison of the levels with target values from the French legislation shows that, except for four polluted sites with critical values (N2: values ≥1 mg kg−1 dry weight) in the smaller bay, PCBs levels throughout the larger and the smaller bay are lower than the accepted values (N1: values <0.5 mg kg−1 dry weight). The PCBs in the sediment cores ranged from 0.8 to 739 ng g−1 dry weight dependent core. Vertical profiles indicated earlier usage of PCBs which coincided with the history of the Toulon Bay. In this study, using alkane, we could follow the PCBs pollution history over about 80 years and estimate a sedimentation rate of about 0.32 cm year in the small Bay of Toulon.Electronic supplementary materialThe online version of this article (doi:10.1186/s40064-016-2715-2) contains supplementary material, which is available to authorized users.
