“…DEHP is the predominant congener in surface water and sediments as a result of urbanisation and industrialisation. This is usually the caused by phthalate ester, which is produced and used most abundantly [19]. In the literature, concentrations of DEHP in surface water are seen to range from undetected to 97.8 mg·L -1 .…”

Abstract. Negative and effectively "irreversible" changes in the environment have often been caused by one or more factors including the intensive development of new technologies, progressing urbanisation andabove all -insufficient knowledge of the properties and toxic effects of many chemicals used. Hundreds of non-natural compounds capable of exerting a negative effect on the natural environment have now been identified in it, including within the broad categories of pesticides, polychlorinated biphenyls and polycyclic aromatic hydrocarbons. Such new and emerging pollutants pose a serious threat to living organisms on account of their tendency to accumulate in certain parts of the environment. Furthermore, the substances in question may prove toxic and harmful to human beings and the environment even at low concentrations. Work described here thus had as its objective an analysis of the pollution of surface water in Poland in terms of content of organic compounds in general, and the aforementioned emerging organic pollutants in particular. Results confirm the presence in waters of such substances as phthalic esters, polybrominated diphenylethers, and organic tin compounds. Reference to average values for individual parameters in the cases of different rivers and lakes further show that, as of 2014-15, the various Polish surface waters researched were characterised by similar levels of pollution, other than in the case of naphthalene.

“…Among the individual PAEs, D n BP, DEHP, and D n OP with the respective mean concentrations of 0.084, 0.307, and 0.077 μg g −1 dw were present in all of samples; by contrast, the other PAEs exhibited relatively low concentrations and detectable frequencies. The concentrations of the six PAEs in sediments samples from WYR were lower than those from the Songhua River in China (Σ 6 PAEs ranged from 0.381 μg g −1 to 2.044 μg g −1 ) [ 2 ] and the suburban southern Jiangsu River (Σ 6 PAEs ranged from 2.3 μg g −1 to 80.1 μg g −1 ) [ 26 ]. The differences in the PAE profiles of sediments from different regions may reflect the predominantly utilized PAE formulation.…”

Contamination of Phthalate Esters (PAEs) in Typical Wastewater-Irrigated Agricultural Soils in Hebei, North China

et al. 2015

The Wangyang River (WYR) basin is a typical wastewater irrigation area in Hebei Province, North China. This study investigated the concentration and distribution of six priority phthalate esters (PAEs) in the agricultural soils in this area. Thirty-nine soil samples (0–20 cm) were collected along the WYR to assess the PAE residues in soils. Results showed that PAEs are ubiquitous environmental contaminants in the topsoil obtained from the irrigation area. The concentrations of Σ6PAEs range from 0.191 μg g−1 dw to 0.457 μg g−1 dw with an average value of 0.294 μg g−1 dw. Di(2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DnBP) are the dominant PAE species in the agricultural soils. Among the DEHP concentrations, the highest DEHP concentration was found at the sites close to the villages; this result suggested that dense anthropogenic activities and random garbage disposal in the rural area are possible sources of PAEs. The PAE concentrations were weakly and positively correlated with soil organic carbon and soil enzyme activities; thus, these factors can affect the distribution of PAEs. This study further showed that only dimethyl phthalate (DMP) concentrations exceeded the recommended allowable concentrations; no remediation measures are necessary to control the PAEs in the WYR area. However, the PAEs in the topsoil may pose a potential risk to the ecosystem and human health in this area. Therefore, the exacerbating PAE pollution should be addressed.

“…Additionally, the PAEs in agricultural soil are primarily from sewage and agricultural plastic film, while the PAEs in an urban environment are more complex and their emissions larger. Wang et al study also shows that the river bank deposits, PAEs content riverbank sediments in urban areas is much higher than suburban and rural (Sun et al, 2016;Wang et al, 2014). This discrepancy indicates that urbanization significantly increases PAE emissions in the local environments.…”

<p>Recent studies have indicated that PAEs (phthalic acid esters) are significant environmental pollutants with carcinogenic, teratogenic, and mutagenic effects. Urban soils can act as both a source and sink for city contaminants. This paper takes Changji, Xinjiang in Northwest China as the study area and explores the pollution characteristics and health risks of PAEs in the urban soils of arid areas. The analysis results indicate average concentration occurrences of 13.77 mg/kg and ranges from 0.29 to 119.72 mg/kg in the study area. Dibutyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP) were the predominant PAEs in the urban soil of Changji. The highest average PAEs concentration appeared in winter, followed by autumn and spring and the lowest in summer; the seasonal variation was significant. The climate characteristics of arid regions and seasonal variations of source emissions were the primary influencing factors. The theoretical values of the non-carcinogenic and carcinogenic risk of PAEs were relatively small, all within the acceptable range. Values of non-carcinogenic risk and carcinogenic risk to children were much higher than the risks to adults. Children were the vulnerable groups most at risk for harmful pollutants, and the safety of their living environment should be the focus of more attention.</p>
