“…In addition, domestic waste from a city, such as building materials, home furnishings, clothing, and food packaging, might contain ldnds of plasticizers and bring PAE pollution to the surrounding water environment. These results fly in the face of other reports for PAEs in the subtropical city, Guangzhou, China (Feng et al 2009). The increasing trends from the upper stream to the lower stream in the Xi'an-Xianyang and Weinan sections were due to the influx of tributaries as well as the distribufion of pollufion sources along the river course.…”

The occurrence and distribution of phthalate acid esters (PAEs) in surface water of the Weihe River basin (eight mainstream sampling points and 15 tributary sampling points) in the Shaanxi section were investigated during the dry season, level period (spring), wet season and level period (autumn). The PAEs tested for were diethyl phthalate (DEP), di-n-butyl phthalate (DBP), dicyclohexyl phthalate (DCHP) and di-(2-ethylhexyl) phthalate (DEHP). The testing proceeded by millipore filtration, then solid phase extraction and then gas chromatography-mass spectrometry determination for all examined PAEs. The monitoring results indicated that, in terms of seasonal changes, concentration of the PAEs in the mainstream is: Dry season > Level period (spring) > Wet season ≈ Level period (autumn). An environmental risk assessment was then performed on PAE pollution levels of the Weihe River basin. This paper employed a risk assessment methodology to evaluate the potential adverse health effects of the individual PAE compounds according to their carcinogenicities. For DEP, DBP and DEHP, a low Risk Index (all of them were lower than the specified level of 1.0) reveals that small non-carcinogenic risks exist resulting from the presence of trace concentrations in the surface water of the Weihe River basin.

“…The transverse distribution of phthalic acid esters is usually site specific and generally inversely proportional to the distance from industrial and commercial sources (Zeng et al , 2009). For example, the phthalic acid ester concentrations in urban soils were found to be higher than those in rural soils, which was due to the intense commercial activities and greater phthalic acid ester discharge from plastic materials in urban regions than rural regions (Sun et al 2013;Xia et al 2011b).…”

Phthalic acid esters have been used as plasticizers in numerous products and classified as endocrine-disrupting compounds. As China is one of the largest consumers of phthalic acid esters, some human activities may lead to the accumulation of phthalic acid esters in soil and result in contamination. Therefore, it is necessary for us to understand the current contamination status and to identify appropriate remediation technologies. Here, we reviewed the potential sources, distribution, and contamination status of phthalic acid esters in soil. We then described the ecological effect and human risk of phthalic acid esters and finally provided technologies to remediate phthalic acid esters. We found that (1) the application of plastic agricultural films, municipal biosolids, agricultural chemicals, and wastewater irrigation have been identified as the main sources for phthalic acid ester contamination in agricultural soil; (2) the distribution of phthalic acid esters in soils is determined by factors such as anthropogenic behaviors, soil type, properties of phthalic acid esters, seasonal variation, etc.; (3) the concentrations of phthalic acid esters in soil in most regions of China are exceeding the recommended values of soil cleanup guidelines used by the US Environmental Protection Agency (US EPA), causing phthalic acid ester in soils to contaminate vegetables; (4) phthalic acid esters are toxic to soil microbes and enzymes; and (5) phthalic acid ester-contaminated soil can be remedied by degradation, phytoremediation, and adsorption.

“…There were exceptions also such as RQ of DEP, DBP and DEHP from UASB + pond process and RQ of DBP and BBP from SBR were more in summer. The exceptions observed in summer season may be due to atmospheric deposition of phthalates and decrease in HRT by rainfall which cause more concentration of phthalates in effluents and hence, increase associated risk in summer (Feng et al, 2009;Sui et al, 2011).…”
