“…This was due to either less agricultural input or greater biodegradation rates in summer (Liu et al 2010a). Wu et al (2011a) found that the dibutyl phthalate degradation rate increased rapidly as temperature increased from 25 to 30°C. Therefore, lower soil temperatures are likely to increase the persistence of phthalic acid esters in soil.…”

“…The soil type, anthropogenic behavior, and land use have been shown to affect the vertical distribution through the degradation and transport of phthalic acid esters, while the rainfall and temperature are likely to affect the distribution through degradation and leaching of phthalic acid esters in the profile of soils (Vikelsøe et al 2002;Wang et al 2013b). Seasonal distribution in phthalic acid esters results from seasonal changes in agricultural inputs as well as temperature and rainfall (Wu et al 2011a). However, these distributions are not independent from each other (Fig.…”

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.

“…The consortium could utilize DBP, DOP, DEP, DMP, DEHP and DPP as the sole source of carbon and energy for growth. The degradation rates of DMP, DEP, DBP were higher than that of DOP, DEHP and DPP [14]. The result indicated that shorter alkyl chain PAEs were degraded rapidly by consortium, while PAEs with longer alkyl chains were more difficult to be degraded.…”

Abstract. In order to enhance the degradation of Di-n-octyl phthalate (DOP).One bacterial strain was inoculated in SBR. Bioaugmentation by inoculating DOP-degrading bacteria effectively shortened the start-up of SBRs and significantly enhanced DOP degradation in bioreactors (p<0.05), 92.3% DOP removal rate was achieved in consortium bioaugmented SBR, which was double of control SBR. The DOP removal in control reactor was only 37%. The results from this study suggest bioaugmentation is an effective and feasible approach for DOP waste water treatment in practical engineering.

“…The bacterial degradation of dialkyl PAEs had been studied previously, however, the strains reported till now were all mesophilic ones, such as Agrobacterium sp. (Wu et al 2011), Pseudomonas fluorescens B-1 (Xu et al 2005), Acinetobacter sp. (Wu et al 2012) and Gordonia sp.…”

An aerobic bacterial strain M11 capable of degrading dibutyl phthalate (DBP) was isolated and identified as Camelimonas sp. This strain could not grow on dialkyl phthalates, including dimethyl, diethyl, dipropyl, dibutyl and dipentyl phthalate, but suspensions of cells could transform these compounds to phthalate via corresponding monoalkyl phthalates. The degradation kinetics of DBP was best fitted by first-order kinetic equation. During growth in Brucella Selective Medium, M11 produced the high amounts of non-DBP-induced intracellular hydrolase in the stationary phase. The DBP hydrolase gene of M11 was cloned, and the recombinant DBP hydrolase had a high optimum degradation temperature (50 °C), and a wide range of pH and temperature stability.
