Phthalate pollution in soil and vegetables plastic agricultural greenhouses has attracted wide concern. Investigating airborne phthalates this environment can improve understanding of air-soil or air-vegetable phthalate migration. However, studies greenhouse air are rare. To fill gap, 25 gas-phase 23 particle-phase samples were collected from 12 typical Shaanxi. 16 types measured by a gas chrom...

Organic micropollutants continue to worsen groundwater pollution, especially in many areas of the world where water resources are becoming scarce. India uses more than any other nation. The main objective this study is evaluate quality Hyderabad, by comprehensively analyzing organic micropollutants. Samples were collected from borewells eight different sites (Begumpet, Bharatnagar, Dundigal, Ju...

Analysis of the natural abundance C content of dibutyl phthalate (DBP) from two edible brown algae, Undaria pinnatifida and Laminaria japonica, and a green alga, Ulva sp., revealed that the DBP was naturally produced. The natural abundance C content of di-(2-ethylhexyl) phthalate (DEHP) obtained from the same algae was about 50-80% of the standard sample and the C content of the petrochemical (...

Tests were performed with the freshwater invertebrates Hyalella azteca, Chironomus tentans, and Lumbriculus variegatus to determine the acute toxicity of six phthalate esters, including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), butylbenzyl phthalate (BBP), di-n-hexyl phthalate (DHP), and di-2-ethylhexyl phthalate (DEHP). It was possible to derive 10-d LC50 (...

The Ames assay was used to investigate the mutagenicity of several phthalate esters as an approximation of their carcinogenic potential. The ortho diesters, dimethyl phthalate (DMP) and diethyl phthalate (DEP) produced a positive dose-related mutagenic response with Salmonella TA100, but only in the absence of S-9 liver enzymes. Dibutyl, di(2-ethylhexyl), mono(2-ethylhexyl), and butyl benzyl ph...

Microbial treatment of bis(2-ethylhexyl)phthalate (BEHP) contaminated soil was evaluated in batch and sequencing batch reactors (SBR) using a mixed bacterial culture isolated from a BEHP-contaminated site. The BEHP-degrading mixed culture had three predominant component strains, Bre ibacterium iodinum, Rhodococcus luteus and Bacillus bre is. For soil slurry SBR studies, the hydraulic residence ...

Twenty four children's toys and child care articles available in the local market of India were analyzed for eight phthalates as children toys are plasticized with phthalates. All toy samples showed the presence of one or more phthalates including di-(2-ethylhexyl) phthalate (96% of the samples), di-iso-nonyl phthalate and di-iso-decyl phthalate (42% of the samples) at a concentration ranging f...

The phthalate acid esters (PAEs), and, in particular, di(2-ethylhexyl) phthalate (DEHP) and its monoester, monoethylhexyl phthalate (MEHP), can adversely affect rodent testes but only at high doses. Rat gonadal zinc levels can be decreased by the injection of DEHP, but not MEHP. The rat prostate gland seems to be particularly sensitive to PAE-induced zinc depletion. PAE-induced changes in male ...
