Plastic debris in the environment contains plasticizers, such as phthalates (PAEs), that can be released during plastic aging. Here, two common materials, an insulation layer of electric cables (polyvinyl chloride, PVC-cables) and garbage bag (polyethylene, PE-bags), were incubated natural seawater under laboratory conditions, PAE migration to phase was studied with varying light bacterial conditions over a 90-day time course. Free PAEs diluted also for degradation. Our results showed that, within first month incubation, both materials significantly leached out into surrounding water. We found di-isobutyl phthalate (DiBP) di-n-butyl (DnBP) main from PE-bags, highest values 83.4 ± 12.5 120.1 18.0 ng g–1 plastic, respectively. Furthermore, dimethyl (DMP) diethyl (DEP) PVC-cables, mass fractions high 9.5 1.4 68.9 10.3 g–1, Additionally, we exposure increased total amount PVC-cables by factor up 5, whereas they had no influence case PE-bags.

Agricultural Plastic Pollution in China: Generation of Plastic Debris and Emission of Phthalic Acid Esters from Agricultural Films

Environmental Science & Technology, Год журнала: 2021, Номер 55(18), С. 12459 - 12470

Agricultural plastic films have been proven highly advantageous, but they also cause pollution of debris and associated chemicals. Phthalates (phthalic acid esters, PAEs), an important additive agricultural films, can be released contaminate the environment. Here, we analyzed usage assessed in China developed a method to estimate PAE emissions from films. Additionally, environmental fate PAEs was evaluated using fugacity-based multimedia model. The film 2017 2,528,600 tons. After recycling water erosion, amount estimated as 465,016 erosion process carried 4329 tons into aquatic During its lifetime, total 91.5 two typical types PAEs. mulching would mostly removed through degradation, while those greenhouse accumulate vegetables. Populated regions exhibited more serious vegetables with no immediate health risks. model well comparable measured concentrations uncertainty analysis based on Monte Carlo method. findings this study demonstrate problem contamination China.

Plastic films have become an integral part of fruit and vegetable production systems, but their release phthalate acid esters (PAEs) is a threat to human health. The kinetics PAEs measures risk are still not well understood. We investigated 50 agricultural films, with concentrations ranging from 2.59 282,000 mg kg–1. seven commercially available film types included were polyvinylchloride (PVC), metallocene polyethylene (mPE), ethylene vinyl acetate (EVA), polyolefin (PO), three mulch films. Bis(2-ethylhexyl) (DEHP) was detected in most its fitted into the first-order kinetic model. rate DEHP negatively related thickness. potential carcinogenic risks air six kinds plastic greenhouses health estimated. found that associated PVC mPE greenhouse warrant greater attention. Though EVA, PO greenhouse, lower risk, we advise keeping ventilated during first month use reduce direct exposure volatile PAEs.
