Experimental PVC Material Challenge in Subjects with Occupational PVC Exposure
BACKGROUND Polyvinyl chloride (PVC) materials have been linked to asthma in several epidemiologic studies, but the possible causal factors remain unknown. PARTICIPANTS We challenged 10 subjects experimentally to degraded PVC products under controlled conditions. All of the subjects had previously experienced respiratory symptoms suspected to be caused by this kind of exposure in their work pl...

متن کاملMigration of Phthalate-based Plasticizers from PVC and non-PVC Containers and Medical Devices
A presença de cinco plastificantes derivados de ftalatos em equipamentos para administração intravenosa de soluções e em hemodialisadores (HD), que são feitos tanto de policloreto de vinila (PVC) quanto de outros materiais poliméricos, foi investigada. Destes ftalatos, o único autorizado por agências reguladoras é o di-(2-etilhexil) ftalato (DEHP) em equipamentos de PVC. A determinação foi feit...
متن کاملChemical Modification of Pvc
The degradation of PVC at a processing temperature is mostly caused by its abnormal and unsta— ble molecular structures. It has been pointed out that its allyl chloride structures play a significant role as the abnormal and unstable structures. Inasmuch as the allyl chloride struc— tures are markedly more chemically active than the normal structure, the selective chemical treatments are applica...
متن کاملGreater fibroblast proliferation on an ultrasonicated ZnO/PVC nanocomposite material
There has been a significant and growing concern over nosocomial medical device infections. Previous studies have demonstrated that embedding nanoparticles alone (specifically, zinc oxide [ZnO]) in conventional polymers (eg, polyvinyl chloride [PVC]) can decrease bacteria growth and may have the potential to prevent or disrupt bacterial processes that lead to infection. However, little to no st...
