Phthalate esters (PAEs) are potentially dangerous chems. in plastic film mulched fields; however, few studies have investigated how to reduce their concentrations in plastic film and soil. In this study, the effects of solar radiation, mech. tension, and soil burial on PAEs concentrations in polyethylene (PE) film and degradable film were investigated, and the half-lives of di-Bu phthalate (DBP) and di(2-ethylhexyl) phthalate (DEHP) in soil also studied. PAEs concentrations in polyethylene films were about twice those in the degradable films; however, PAEs concentrations in all exptl. films were similar after 1-yr of field exposure. Mech. tension had no effect on the PAEs concentrations of polyethylene films, but increased the detected concentrations of PAEs in degradable films by 34%-120%. After 4-years of burial, the PAEs concentrations in films decreased by 79.2%-98.0%, and mech. tension promoted the reductions However, there was little difference in PAEs concentrations between the buried soils with and without films, indicating the released PAEs reduced quickly in soil. Also, the half-lives of DBP and DEHP were 2.4-4.6 days and 18.5-41.4 days, resp. Overall, the results presented herein provide reasonable approaches to reduce the concentrations of PAEs in plastic films and soils. In the experiment, the researchers used many compounds, for example, Dicyclohexyl phthalate (cas: 84-61-7Safety of Dicyclohexyl phthalate).
Dicyclohexyl phthalate (cas: 84-61-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Safety of Dicyclohexyl phthalate
