Phthalate Ester Plasticizers: A New Class of Marine Pollutant
Samples consisting of water, sediment, air, and biota from the Gulf of Mexico and of water and air from the North Atlantic were analyzed and found to contain two phthalate esters, di- (2-ethylhexyl) phthalate (DEHP) and di- n -dibutyl phthalate (DBP); the concentrations of polychlorinated biphenyls (PCB's) and DDT's ( p, p ′-DDT and p, p ′-DDE)
Phthalate ester plasticizers, DDT, DDE and polychlorinated
The levels of phthalate ester plasticizers, DDT, DDE and polychlorinated biphenyls (PCBs) were determined in the tissues of 18 species of marine organisms from the northwestern Gulf of Mexico. Low levels of the most widely used phthalate, di- (2-ethylhexyl) phthalate, were found in the majority of the samples; no other phthalates were detected.

Phthalate Ester Plasticizers: A New Class of Marine Pollutant
Phthalic acid esters (PAEs) are widely used as additives in plastic resins such as polyvinyl resin, cellulosic and polyurethane polymers for the manufacture of building materials, home furnishings,...
- What is plasticizer phthalate?
- Plasticizer phthalate is a pollutant. Its teratogenic or carcinogenic effects on human. Phytotoxic effects of phthalate and its transmission through food chain. Abatement of phthalate via bioremediation. Microbe-mediated soil-phthalate bioaugmentation approaches.
- What are phthalates (Paes)?
- Phthalates (PAEs) are the di-alkyl or di-alkyl-aryl esters of phthalic acid (PA), the main precursor of phthalate. Phthalic acid consists of two carboxylic groups at the ortho position of a benzene ring. Commonly in the generic formula of phthalate, there are linear or branched side chains of alkyl groups having 1–28 carbon atoms.
- Do phthalate degraders convert Paes into intermediate forms?
- In laboratories, individual potent phthalate degraders have been studied that are known to convert PAEs into their intermediate forms (Chatterjee and Dutta, 2008a; Chatterjee and Dutta, 2008b; Wu et al., 2010a). However, in nature, groups of phthalate utilizing microbes act together cooperatively to completely degrade the PAEs into neutral forms.
- How many esterification reactions lead to conversion of di-alkyl phthalates to phthalic acids?
- Two consecutive esterification reactions lead to the conversion of di-alkyl phthalates to phthalic acids.
- Is bioremediation a solution to phthalate toxicity?
- Nevertheless, the release of these compounds in the environment is unabated. Bioremediation has been suggested as one of the ways of mitigating this menace, but studies regarding the field applications of phthalate utilizing microbes for this purpose are limited.
- What is biodegradation of phthalates?
- 5.1. Bacterial degradation of phthalates Biodegradation is one of the safest processes to eliminate phthalate contamination from the environment where microbes convert the toxic phthalates into relatively less toxic or nontoxic forms.
