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) were

Phthalate ester plasticizers: a new class of marine pollutant.
Phthalate ester plasticizers have been detected in the open-ocean environment. 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

duced phthalate plasticizers, di-2-ethyl-hexyl phthalate (DEHP) and di-n-butyl phthalate (DBP), in marine water, sedi-ment, air, and biota was therefore initi-ated. The results we obtained clearly
- What are phthalate esters?
- Phthalate esters are ubiquitous contamination in the Chinese Marginal seas. DEHP, DiBP and DnBP are more abundant in marine sediment. Total organic carbon content is an important factor effect the accumulation of PEs in the sediment. The inventories of the ∑6PAEs were 20.73 tons in the Bohai Sea and 65.87 tons in the Yellow Sea.
- What are phthalic acid esters (Paes) plasticizers?
- Electronic address: nzg@tju.edu.cn. Phthalic acid esters (PAEs) plasticizers are virulent endocrine disruptors that are mixed into plastics while fabricating and can filter out once they release into the surrounding environments. Plastic surfaces serve as new habitats for microorganisms, referred to as 'plastisphere'.
- Can Microbacterium degrade phthalate & bis 2 ethylhexyl phthalates?
- In this study, by screening the natural microbial community on plastic debris that had been deployed in situ for up to 20 months, a novel marine bacterium, Microbacterium esteraromaticum DEHP-1, was successfully isolated, which could degrade and mineralize 10-200 mg/L dibutyl phthalate (DBP) and bis (2-ethylhexyl) phthalate (DEHP).
- Do microorganisms metabolize plasticizers in the Marine 'plastisphere'?
- Previous metagenomic investigations of the 'plastisphere' indicated that marine plastic surfaces may harbor microbes that degrade PAEs plasticizers. To our knowledge, the potential of microorganisms in the marine 'plastisphere' to metabolize PAEs is poorly understood.
