“…A number of investigations have successfully demonstrated in situ microbial degradation for a range of phthalic acid esters under aerobic and abiotic conditions in soil, natural waters, and wastewaters (He et al 2012). However, microorganisms do not completely degrade and remove phthalic acid esters from soil or aqueous solution .…”

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.

“…Research has been carried out related to the degradation of phthalate esters by many methods (Xu et al 2013;Sarkar et al 2013;Wu et al 2013;He et al 2013). Very few reports are available in the literature related to the degradation of phthalate esters using TiO 2 -based photocatalytic degradation (Jiana et al 2013;Jing et al 2011;Ding et al 2008).…”

Undoped and Ni-doped TiO 2 nanoparticles are synthesized using sol-gel technique. The physical, structural, optical and thermal properties of the samples are investigated using X-ray powder diffraction, Fourier transform infrared spectroscopy, transmittance electron microscopy, UV-visible diffuse reflectance and thermogravimetric analysis. The photocatalytic activity of the samples is investigated by the photocatalytic degradation of phthalate esters. Phthalate esters have been considered as endocrine disrupting compounds. Nidoped TiO 2 samples show better photocatalytic activity as compared to undoped TiO 2 sample. The greater photocatalytic activity of doped samples as compared to undoped TiO 2 can be attributed to the production of more number of electron-hole pairs in doped samples.

“…Roslev et al (2007) investigated the fate of dimethyl phthalate (DMP), dibutyl phthalate (DBP), butyl benzyl phthalate (BBP) and di-(2-ethylhexyl) phthalate (DEHP) in a full-scale activated sludge WWTP with biological removal of nitrogen and phosphorus. He et al (2013) investigated the biodegradation of di-n-butyl phthalate by a stable bacterial consortium enriched from the activated sludge and identified the dominant microorganisms in the consortium by denaturing gradient gel electrophoresis (DGGE), and they found the existence of Gordonia sp., Burkholderia sp. and Achromobacter sp.…”

Di-n-butyl phthalate is widely used as plasticizer, which has been listed as priority pollutant due to its toxic and ubiquitous characteristics. It is difficult to remove by the conventional wastewater treatment processes. In this paper, the feasibility of using Micrococcus sp. to bioaugment a sequencing batch reactor for degrading di-n-butyl phthalate (DBP) was investigated. The terminal restriction fragment length polymorphisms (T-RFLP) were used to analyze the variation of microbial community in the reactor. The experimental results showed that for the bioaugmented reactor, the removal efficiency of DBP was about 85 % as compared to 25 % of the control reactor when initial DBP concentration was 100 mg/L. The bioaugmentation not only enhanced the removal efficiency of target compound, but also shortened the start-up time of the reactor. The kinetics of DBP degradation conformed to the first-order model in both reactors. The T-RFLP analysis indicated the bacterial community changes in the acclimated activated sludge and the introduced Micrococcus sp. during the operational process.
