“…These compounds were found to be characteristics of endocrine disrupters, carcinogens, teratogens, and mutagens (Liu et al 2012a;Shi et al 2012;Balbuena et al 2013) and occurred ubiquitously in the environment recently (Cecinato et al 2012;Liu et al 2012bLiu et al , 2014Zhang et al 2012;Masood and Malik 2013;Xu et al 2014). Dimethyl phthalate (DMP), diethyl phthalate (DEP), and di-noctyl phthalate (DnOP) have been proposed as priority pollutants by the Chinese government because of their pronounced tendency to accumulate in biological systems and their potential damage to the human body through contamination of the food chain (Environmental Monitoring Center of China 1992).…”

The contamination of phthalate esters (PAEs) has become a potential threat to the environment and human health because they could be easily released as plasticizers from the daily supply products, especially in polyethylene films. Concentration levels of total six PAEs, nominated as priority pollutants by the US Environmental Protection Agency (USEPA), were investigated in soils and vegetables from four greenhouse areas in suburbs of Nanjing, East China. Total PAEs concentration ranged from 930±840 to 2 450±710 μg kg −1 (dry weight (DW)) in soil and from 790 ± 630 to 3 010 ± 2 130 μg kg −1 in vegetables. Higher concentrations of PAEs were found in soils except in Suo Shi (SS) area and in vegetables, especially in potherb mustard and purple tsai-tai samples. Risk assessment mainly based on the exposures of soil ingestion and daily vegetable intake indicated that bis(2-ethylhexyl) phthalate (DEHP) in the samples from Gu Li (GL) and Hu Shu (HS) exhibited the highest hazard to children less than 6-year old. Therefore, the human health risk of the PAEs contamination in soils and vegetables should greatly be of a concern, especially for their environmental estrogen analog effects.

“…Phthalic acid esters are readily discharged from many plastic applications to the surrounding environment because they are not chemically bonded to plastic polymers (Li et al 2004). These are some of the reasons that cause phthalic acid ester contamination in water, sediment, and soil Dargnat et al 2009;Liu et al 2014). Moreover, phthalic acid esters are semi-volatile compounds (Mo et al 2008) and their half-lives in soil, which relate to their structure characteristics and environment, range usually from <1 week to several months or longer in anaerobic or cold environments depending on their molecular structure characteristics and environmental conditions (Stales et al 1997).…”

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.

“…As a result of rapid economic development of the Pearl River Delta (PRD) in recent decades, the pollution of organic pollutants in the water environment of the Pearl River was becoming more serious,thus potenially threatening human health and ecological security in this area [1,2]. Some kinds of organic pollutants, such as brominated flame retardants(BFRs)-Polybrominated diphenyl ethers (PBDEs), Polycyclic aromatic hydrocarbons(PAHs), Bisphenol A (BPA) and other pollutants, have been detected in water of East river, which was the one of upstream rivers of the Pearl River [3,4].…”

“…Some kinds of organic pollutants, such as brominated flame retardants(BFRs)-Polybrominated diphenyl ethers (PBDEs), Polycyclic aromatic hydrocarbons(PAHs), Bisphenol A (BPA) and other pollutants, have been detected in water of East river, which was the one of upstream rivers of the Pearl River [3,4]. For example, The 16 kinds of PAEs concentrations in riverine sediments in the PRD region ranged from 0.567 to 47.3µg/g dry weight (dw), with the mean and median concentrations of 5.34µg/g dw and 2.15µg/g dw, respectively [1].The concentrations of BDE-209 in sediments of Pearl River in china ranged from 30 to 7340 ng/g [5]. Therefore, elimination of organic pollutants from river water environment becomes an urgent task.…”

Abstract. The efficiency of organic pollutants removed by an integrated river water purification demonstration project built in the Danshui River was investigated. Preferable remvoal results were obtained in the operation process of this project. More than 40% of polycyclic aromatic hydrocarbons (PAHs) were removed from river water by the demonstration project, and the removal rates for five kinds of homologues for Naphthalene, fluorene, phenanthrene, pyrene and fluoranthene were 44.13%-59.23%, 44.1%-54.61%, 50.90%-54.70%, 61.88%-80.61% and 44.83%-56.64%, respectively. Decabromodiphenyl ether(BDE-209) and bisphenol A(BPA) could be fully removed by this project.The results suggested that demonstration project could effectively remove the organic pollutants from river water and could be widely applicated in river water purification.
