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

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: 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,...
Global Transport of Organic Pollutants: Ambient
Polychlorobiphenyls, total DDT, dieldrin, chlordane, and two phthalate ester plasticizers were also found in the samples. The concentrations of pollutants in the atmosphere remote from continental sources are good measures of the minimum concentrations of air pollutants on Earth. Formats available
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
- Do plastic products release phthalate esters?
- Plastic properties and external environmental factors can affect the release. Phthalate esters (PAEs) are predominant additives in plastics, their widespread contamination in aquatic environments has raised global concern. Here, twelve plastic products were prepared as microplastics to investigate their release behaviors of PAEs.
- 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.
- Are microplastics a potential source of Paes in aquatic environments?
- This study revealed that microplastics are the potential source of PAEs in aquatic environments, with the estimated annual mass loads between 57.8 and 16,100 kg. Six out of the 15 PAEs, including DMP, DEP, DiBP, DBP, DEHP, and BBP, were detected in water after 14 days of incubation. The leaching abilities of PAEs were plastic type-specific.
- Do water chemical properties affect the migration of Paes from microplastics?
- Water chemical properties such as pH and salinity could affect the migration of PAEs from microplastics in aquatic environments. The pseudo-first-order model fits well with the leaching behavior of PAEs from microplastics into water.
- Do lipophilic Paes migrate from plastic containers into cooking oil and mineral water?
- Xu et al. (2010) have investigated the migration of PAEs from plastic containers into cooking oil and mineral water, and higher PAEs were observed in the former one than those in the latter one, as the lipophilic PAEs, especially those with long chains, are prone to be transferred into the fat-enriched matrix (Kappenstein et al., 2012).
- Do Paes release into water bodies from plastic products?
- Additionally, it could be speculated that PAEs may also directly release into water bodies from plastic products during their use in contact with water, such as laundry bag (PET), shoe brush (PP), bath ball (PE) and drain pipe (PVC).
