“…The PAE concentrations in GL soils were generally lower than HS which is as high as 2 450±710 μg kg −1 DW although the planting time (4∼6 y) of GL greenhouse was longer than HS and agricultural films of poor quality were used. The reasons were assumed to be the effective field managements such as periodical uncovering of agricultural films for better venting to cut down plant diseases and insects growth and to accelerate the PAE removing from soils by chemical degradation and biodegradation (Pradeep and Benjamin 2012). Such a management pattern could also increase the transfer of PAEs from inside to outside the greenhouse, which further reduced the chance of PAE accumulation in soils.…”

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.

“…There are some fungi capable of degrading DEHP in soil (Pradeep and Benjamin 2012). The numbers of these fungi may significantly increase after the fungi adapt to the presence of DEHP and use DEHP as an additional source of carbon and energy to grow.…”

This study aimed to evaluate the effects of poultry manure (PM) on soil biological properties in DBP- and DEHP-contaminated soils. An indoor incubation experiment was conducted. Soil microbial biomass C (Cmic), soil enzymatic activities, and microbial phospholipid fatty acid (PLFA) concentrations were measured during incubation period. The results indicated that except alkaline phosphatase activity, DBP and DEHP had negative effects on Cmic, dehydrogenase, urease, protease activities, and contents of total PLFA. However, 5 % PM treatment alleviated the negative effects of PAEs on the above biochemical parameters. In DBP-contaminated soil, 5 % PM amendment even resulted in dehydroenase activity and Cmic content increasing by 17.8 and 11.8 % on the day 15 of incubation, respectively. During the incubation periods, the total PLFA contents decreased maximumly by 17.2 and 11.6 % in DBP- and DEHP-contaminated soils without PM amendments, respectively. Compared with those in uncontaminated soil, the total PLFA contents increased slightly and the value of bacPLFA/fugalPLFA increased significantly in PAE-contaminated soils with 5 % PM amendment. Nevertheless, in both contaminated soils, the effects of 5 % PM amendment on the biochemical parameters were not observed with 10 % PM amendment. In 10 % PM-amended soils, DBP and DEHP had little effect on Cmic, soil enzymatic activities, and microbial community composition. At the end of incubation, the effects of PAEs on these parameters disappeared, irrespective of PM amendment. The application of PM ameliorated the negative effect of PAEs on soil biological environment. However, further work is needed to study the effect of PM on soil microbial gene expression in order to explain the change mechanisms of soil biological properties.

“…An increased quantity of the plasticizer in the plastics decreases its tensile strength, and thus, increases plasticity of the final product. Significant negative effect associated with these plasticized PVC products is the leaching out of phthalates from the polymer skeleton into the environment [4]. It is due to the absence of chemical bonding between the polymer mesh and the plasticizer, which results in the gradual migration of phthalate from plastic products into the surrounding environment (Fig.…”

“…Phthalates or esters of phthalic acid are a class of xenobiotic organic compounds widely employed to make plastic goods more flexible. Some of the commonly used phthalates are described in Table 1 [2,3], which are not chemically bound to the polymer mesh, and hence, they would easily migrate from plastic products into the surrounding environments [4][5][6]. Many experimental studies (in silico, in vitro mechanistic, pre-clinical and clinical) have shown that phthalates act as endocrine disruptors in vivo, apart from causing various health problems including hepatomegaly, osteoporosis, peroxisome proliferation, feminization of boys, reduction in body weight, skin and breast cancers, etc.…”
