“…The levels reported by Greichus et al (1977) were two-fold greater in magnitude compared to the levels detected in the present study. Compared to the concentrations reported from other developing and industrially developed countries around the world, PCB concentrations measured in the present study were similar to those reported by Guzzella et al (2005), Rajendran et al (2005), He et al (2006), El-Khady et al (2007), and Verhaert et al (2013) (Table 3). All of these studies were conducted in developing countries, namely, India, China, Egypt and Democratic Republic of Congo, respectively.…”

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.

“…In these countries, PCBs and PBDEs are continuously discharged through human activity, and OCPs such as DDTs and HCHs are still used for the agriculture application (Guzzella et al, 2005), which could be the potential important sources of POPs to the Tibetan Plateau transported by LRAT. Previous works also pointed out that in summer, the Indian monsoon not only brings water vapor to provide moisture and precipitation (Tian et al, 2007), but also carries on POPs, such as DDTs and PCBs, from India to the Tibetan Plateau Sheng et al, 2013).…”

a b s t r a c tPristine mountains are ideal settings to study transport and behavior of persistent organic pollutants (POPs) along gradients of climate and land cover. The present work investigated the concentrations and patterns of 28 organochlorine pesticides (OCPs), 25 polychlorinated biphenyl (PCBs), 13 polybrominated diphenyl ethers (PBDEs), and 3 hexabromocyclododecane (HBCDs) isomers in the air of the Shergyla Mountain, southeastern Tibetan Plateau. Endosulfan _, hexachlorobenzene, pentachlorobenzene, hexachlorocyclohexanes and dichlorodibenzotrichloroethane and its degradation products (DDTs) were the predominant compounds while PBDEs and HBCDs showed the lowest background concentrations. Most of the target POPs had significantly higher concentrations in summer than those in winter. Increasing trends of the concentrations of DDTs and endosulfan were found with increasing altitude on the western slope in the Shergyla Mountain. Potential forest filter effect was observed based on the lower air concentrations of the target POPs in the forest than the ones out of the forest.

“…The concentrations of these pollutants observed in many agricultural soil samples were very high (Al-Wabel et al, 2011;Hoai et al, 2010;Kumari et al, 2008;Liu et al, 2009;Senthilkumar et al, 2009;Xu et al, 2013a,b). A number of studies revealed the prevalence of OCPs and PCBs in various environmental matrices, including food commodities in India (Aktar et al, 2009;Chakraborty et al, 2010;Chowdhury et al, 2007;Devanathan et al, 2009;Guzzella et al, 2005;IPEN, 2006;Kole et al, 2001;Kumar et al, 2009;Prakash et al, 2004;Senthilkumar et al, 2001;Someya et al, 2009;Zhang et al, 2008). Today, everything from food to groundwater and drinking water is contaminated severely with OCPs, therefore understanding the environmental fate of OCP residues is a key issue.…”
