“…However, the ΣPAH concentrations in the present study were much lower than those previously reported in the following coastal regions: Yeongil Bay (205-10,686 ng/g dry wt) (Moon et al, 2001a), Ulsan Bay (6.0-2,396 ng/g dry wt) (Moon et al, 2001b), Masan Bay (207-2,670 ng/g dry wt) (Yim et al, 2005), Gamak Bay (130-2,100 ng/g dry wt) (Li et al, 2007), Masan Bay (130-3,964 ng/g dry wt) (Choi et al, 2005b), Ulsan Bay (141-8,257 ng/g dry wt) (Choi et al, 2005a), and the Mokpo coast, Korea (43-7,902 ng/g dry wt) . In addition, the concentrations of COP in the present study were much lower than those reported in Boston Harbor, USA (260-12,000 ng/g dw) (Eganhouse and Sherblom, 2001), Cootes Paradise, Ontario, Canada (150-38,000 ng/g dw) (Mayer et al, 2007), Santa Monica Bay, USA (70-45,260 ng/g dry wt) (Venkatesan et al, 2010), and Guanabara Bay, Brazil (330-40,000 ng/g dry wt) (Carreira et al, 2004). Therefore, it can be concluded that sewage pollution in the Gunsan coast is low, compared to some other locations worldwide.…”

Polycyclic aromatic hydrocarbons (PAHs), butyltins (BTs), nonylphenol (NP), and fecal sterols concentrations in sediments were investigated from Gunsan coast of Korea to evaluate organic pollution from anthropogenic activities. Sediment toxicity was also examined by bacterial bioluminescence toxicity test (Vibrio fischeri). The concentrations of 16 PAHs in sediments ranged from 67.9 to 425 ng/g dry wt; BTs ranged from 2.79 to 14.1 ng Sn/g dry wt; NP ranged from 20.7 to 2171 ng/g dry wt; and coprostanol, a fecal sterol, ranged from 7.60 to 245 ng/g dry wt. Effective concentration 50% (EC 50 ) of sediments ranged from 0.38 to 23.8 mg/ mL. Most of the chemicals were present at levels lower than or comparable to the previously reported values from Korea. However, NP levels in the present study were in the high range of levels reported from the Korean coast, and 40% of the measured samples exceeded screening and ecotoxicological values of NP suggested by the Netherlands and Canada. This suggests that an ongoing source of NP is a serious concern in the Gunsan coast. High levels of contaminants were found in the proximity of potential sources, such as the outfall of a wastewater treatment plant for NP, an anthracite-fired power plant for PAHs, and ports for BTs, fecal sterols, and sediment toxicity. This indicates that Gunsan coast has various potential sources of marine sediment contaminants.

“…They also find application as building block chemicals that are used in making fragrances, surfactants, thermoplastic elastomers, antioxidants, adhesives, coatings, carbonless copy-paper and high performance rubber paper [7]. The distribution of nonylphenol in aquatic environment in several rivers in Europe and USA has been reported where it has been found to be mainly concentrated in sediment [3,5,[8][9][10]. Various studies have also confirmed that nonylphenol present risks to aquatic organisms, especially zooplanktons and benthic macro-invertebrates in areas of high chronic exposure to high concentrations [11,12].…”

The continuous uncontrolled discharge of pollutants into aquatic systems in developing countries like Nigeria has prompted a more sensitive assessment of the level of pollutants inhabiting the environment. Sediments and waters of River Ogun and River Ibeche in southwestern part of Nigeria were collected and analysed for 4-t-Octyphenol (4-t-OP), 4-nonylphenol (4-NP) and Bisphenol-A (BPA), that have been shown to possess endocrine-disrupting properties. Prior to analysis by GC-MS technique, targeted compounds were extracted from samples by ultrasonication and liquid-liquid extraction, respectively. Physicochemical properties of the samples such as temperature, pH, total organic carbon and particle size distribution were also determined. 4-NP and 4-t-Op were detected in all the water samples with concentration ranging between 43.9 ng/L -79.4 ng/L and 57.1 ng/L -68.6 ng/L, respectively. No trace of BPA was found in all the water samples collected. However, BPA in sediment samples from both rivers ranged from non detectable to ≤0.4 ng/g, while 4-t-OP and 4-NP were between 2.2 ng/g -24.5 ng/g and 1.1 ng/g -79.4 ng/g, respectively. The presence of these compounds in surface water and sediments may be attributed to the release of pollutants into the studied rivers from both domestic and industrial activities. Further studies are however needed to investigate the potential ecological and health effects of these compounds on aquatic organisms that inhabit the rivers.

“…Those chemicals are commonly used in household and industrial products and can enter the environment through municipal and industrial wastewater discharges, agricultural runoff, solid-waste leaching, and garbage incineration (Campbell et al 2006;Kawagoshi et al 2003;Sidhu et al 2005). The occurrence of EDCs in the environment has been reported worldwide (Gong et al 2009;Mayer et al 2007;Pojana et al 2007;Yoon et al 2010), and increasing evidences have suggested possible adverse effects of EDCs to aquatic organisms even at environmentally relevant concentrations (Bahamonde et al 2014;Vajda et al 2011;Woodling et al 2006).…”

Occurrence of five endocrine-disrupting chemicals (EDCs)-bisphenol-A (BPA), triclosan (TCS), 17a-ethinyl estradiol (EE2), benzophenone-3, and 4-methylbenzylidene camphor-were monitored in East Lake, the largest urban lake in China. Other than EE2, all selected EDCs were detected at least once in the lake water with concentrations B89.1 ng/L. EDCs were detected with greater occurrence in spring than in other seasons. In lake sediment, TCS was detected at the greatest concentration (30.9 ng g -1 ), whereas BPA and EE2 were not detected. Spatial distribution of the EDCs in the lake water and the lake sediment showed similar patterns, and greater EDC residuals were found from those sites with known wastewater input. The linear adsorption coefficients (K d ) varied from 17.9 to 1,017 L kg -1 and were related to the octanolwater partition coefficient (K ow ) values of the compounds. Photodegradation was a major process removing the EDCs from the lake water, and the presence of dissolved organic material and NO 3 -in the lake water can accelerate the photodegradation process. Degradation of the EDCs in the lake sediment was relatively slow and occurred mainly due to the microbial processes. All compounds were found more persistent under anoxic conditions than under oxic conditions.
