Dehp dissipation from plastic
WebThe other non-DEHP plastic introduced for storing platelet concentrates was PL-732, referred to as ‘polyolefin’, with no liquid plasticizers and, thus, there is no concern over migration of them 19. Being a non-polar polymer, PL-732 is neither weldable nor sealable by high frequency but has a high gas permeability. WebHere, bacterial community and PAE-degrading genes in root-associated niches were analyzed between low (Fengyousimiao) and high (Hhang) PAE-accumulating rice cultivars exposed to di-(2-ethylhexyl) phthalate (DEHP). DEHP dissipation percentages in rhizosphere of Hhang were significantly higher than those of Fengyousimiao.
