“…Heavy metals, nitrites and organic pollutants in contaminated water and soil could increase the potential risk of cancers (Montesano and Hall, 2001;Hansen et al, 2003;Galiani et al, 2005;Wild et al, 2006;He, 2013). It is reported that contaminated water and food could even increase the morbidity and mortality of cancers, especially digestive cancers (Baudouin et al, 2002;Boffetta, 2006;Beaumont et al, 2008;El-Tawil, 2010;Gallagher et al, 2010;Ebenstein, 2012;Gao et al, 2012;Sun et al, 2014;Zhang et al, 2014;Zhao et al, 2014).…”

Impacts of Soil and Water Pollution on Food Safety and Health Risks in China AbstractEnvironmental pollution and food safety are two of the most important issues of our time. Soil and water pollution, in particular, have historically impacted on food safety which represents an important threat to human health. Nowhere has that situation been more complex and challenging than in China, where a combination of pollution and an increasing food safety risk have affected a large part of the population. Water scarcity, pesticide over-application, and chemical pollutants are considered to be the most important factors impacting on food safety in China. Inadequate quantity and quality of surface water resources in China have led to the long-term use of waste-water irrigation to fulfill the water requirements for agricultural production. In some regions this has caused serious agricultural land and food pollution, especially for heavy metals. It is important, therefore, that issues threatening food safety such as combined pesticide residues and heavy metal pollution are addressed to reduce risks to human health. The increasing negative effects on food safety from water and soil pollution have put more people at risk of carcinogenic diseases, potentially contributing to 'cancer villages' which appear to correlate strongly with the main food producing areas. Currently in China, food safety policies are not integrated with soil and water pollution management policies. Here, a comprehensive map of both soil and water pollution threats to food safety in China is presented and integrated policies addressing soil and water pollution for achieving food safety are suggested to provide a holistic approach.

“…In Japan, the concentrations of DEHP in the sediments of Jinzu River and Oyabe River were 0.02 μg/g to 0.30 μg/g and 0.02 μg/g to 1.80 μg/g, respectively [42]. The similar PAEs concentrations were also found in some sediments in China, including of Kaohsiung Harbor (DEHP, 0.40 μg/g to 34.80 μg/g; DBP, ND to 1.31 μg/g; DMP and DEP, ND) [43], the Pearl River Delta (DEHP, 0.03 μg/g to 170.0 μg/g; DBP, 0.310 μg/g to 2.8 μg/g; DEP, 0.009 μg/g to 0.12 μg/g; DMP, 0.003 μg/g to 0.20 μg/g) [44], and urban lakes in Guangzhou (DEHP, 0.21 μg/g to 14.16 μg/g; DBP, 0.082 μg/g to 1.26 μg/g; DEP, 0.028 μg/g to 1.05 μg/g; DMP, 0.001 μg/g to 0.43 μg/g) [45]. In most of the cases, DBP and DEHP were observed as the major PAEs in soils, attributing to their high octanol/water partition coefficient (Kow), which represented the migration of hydrophobic organic matters (PAEs in this study) between soils and water [46].…”

When used as highly produced chemicals and widely used plasticizers, Phthalate acid esters (PAEs) have potential risks to human life and the environment. In this study, to assess the distribution and fate of PAEs, specifically inside a full-scale horizontal subsurface flow constructed wetland, four PAEs including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), and bis (2-ethylhexyl) phthalate (DEHP) were investigated. In effluent, PAEs concentration decreased 19.32% (DMP), 19.18% (DEP), 19.40% (DBP), and 48.56% (DEHP), respectively. Within the wetland, PAEs partitioned in water (0.18–1.12 μg/L, 35.38–64.92%), soil (0.44–5.08 μg/g, 1.02–31.33%), plant (0.68–48.6 μg/g, 0.85–36.54%), air and biological transformation (2.72–33.21%). The results indicated that soil and plant adsorption contributed to the majority of PAE removal, digesting DMP (19.32%), DEP (19.18%), DBP (19.40%), and DEHP (48.56%) in constructed wetlands. Moreover, the adsorption was affected by both octanol/water partition coefficient (Kow) and transpiration stream concentration factors (TSCF). This work, for the first time, revealed the partition and fate of PAEs in constructed wetlands to the best of our knowledge.

“…Organic pollutants in rivers included Dichlorodiphenyltrichloroethane [ 25 , 26 ], OCPs [ 27 , 28 ], PCBs, Hexachlorocyclohexanes (HCHs) and PAHs [ 29 , 30 ]. These organic pollutants are classical examples of POPs, with worldwide concern owing to their persistence, bioaccumulative ability, and potential negative impacts on humans and animals [ 31 ]. We have previously reported the toxicological significance of organic pollution of the drinking water source and its safety assessment to human health [ 32 , 33 ].…”

An increasing number of industrial, agricultural and commercial chemicals in the aquatic environment lead to various deleterious effects on organisms, which is becoming a serious global health concern. In this study, the Ames test and SOS/umu test were conducted to investigate the potential genotoxicity and mutagenicity caused by organic extracts from drinking water sources. Organic content of source water was extracted with XAD-2 resin column and organic solvents. Four doses of the extract equivalent to 0.25, 0.5, 1 and 2L of source water were tested for toxicity. All the water samples were collected from six different locations in Guangdong province. The results of the Ames test and SOS/umu test showed that all the organic extracts from the water samples could induce different levels of DNA damage and mutagenic potentials at the dose of 2 L in the absence of S9 mix, which demonstrated the existence of genotoxicity and mutagenicity. Additionally, we found that Salmonella typhimurium strain TA98 was more sensitive for the mutagen. Correlation analysis between genotoxicity, Organochlorine Pesticides (OCPs) and Polycyclic Aromatic Hydrocarbons (PAHs) showed that most individual OCPs were frame shift toxicants in drinking water sources, and there was no correlation with total OCPs and PAHs.
