“…Furthermore, this work shows that a single PAE congener is highly correlated with the Σ 6 PAEs in surface water of northwest of Dongguan city. The highest Pearson correlation coefficient (R) of 0.803 (p < 0.01) between the DnBP concentration and Σ 6 PAEs suggests that the DnBP is a predictive indicator for the Σ 6 PAEs in surface water, which agree with the previous study in other surface water (Zeng et al, 2008). There is significant variation in the Σ 6 PAEs in surface water from northwest of Dongguan city (Fig.…”

“…PAEs with shorter side chains such as DiBP and DEP were more water soluble, whereas PAEs with longer side chains like DEHP were more lipophilic and mainly detected as adsorbed in sediment. The major PAEs detected in this study were comparable to the previous studies in the PRD region (Cai et al 2007;Zeng et al 2008).…”

The pollution levels of typical semivolatile organic compounds (SVOCs) consisting of 15 polycyclic aromatic hydrocarbons (PAHs), 20 organic chlorinated pesticides (OCPs), and 15 phthalate esters (PAEs) were investigated in small rivers running through the flourishing cities in Pearl River Delta region, China. The concentrations of ∑15PAHs were 2.0-48 ng/L and 29-1.2×10 3 ng/g in the water and sediment samples, respectively. The ∑20OCPs were 6.6-57 ng/L and 9.3-6.0×10 2 ng/g in the water and sediment samples, respectively. The concentrations of ∑15PAEs were much higher both in the water and sediments. The partition process of the detected SVOCs between the water and sediment did not reach the equilibrium state at most of the sites when sampling. The combustion of petroleum products and coal was the major source of the detected PAHs. The OCPs were mainly historical residue, whereas the new inputs of dichlorodiphenyltrichloroethane (DDT), chlordane, and endosulfan were possible at several sites. The industrial and domestic sewage were the major source for the PAEs; storm water runoff accelerated the input of PAEs. No chronic risk of the SVOCs was identified by a health risk assessment through daily water consumption, except for the ∑20OCPs that might cause cancer at several sites. Nevertheless, the integrated health risk of the SVOCs should not be neglected and need intensive investigations.

“…Excess loads of nutrients have caused eutrophication in most urban lakes (Birch and McCaskie 1999;Jin et al 2005). Other pollutants-such as persistent organic pollutants (Ge et al 2014;Wang et al 2002), heavy metals (Mahler et al 2006), and phthalate esters (Zeng et al 2008)-were also detected at increased concentrations in urban lakes. For protection and remediation purpose, it is important to understand the occurrence and fate of environmental pollutants in urban lake systems.…”

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.
