Influence of time on phthalate esters concentrations in vehicle plastic materials during vehicle operation

Popis výsledku v původním jazyce

The aim of this work was determined the concentrations of phthalic acid esters (PAEs) in plastic materials used in automobiles and monitored the changes in concentrations over time. The phthalates can be released into the car interior during the operation of the vehicle and thereby inhaling by the driver, or the PAEs can migrate from plastics to surrounding contact materials. Esters of phthalic acid are used as plasticizer of plastics. They are not chemically bonded in polymers, so they can migrate into materials, which are in contact with them, leach or evaporate into the environment. Phthalic acid esters have teratogenic and carcinogenic effects and negative effect on the male reproductive system. In this study was determined the most commonly used phthalates: dibutyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP). Nine samples of plastic materials that are used in the car interior were analysed. The samples were new plastics which were made for car mounting. Each sample of plastic material was subdivided into the individual components from which was the sample consisted and each part of each sample was analysed separately. The first sample analysis was performed immediately after the obtaining of plastic samples (after the plastics production) and subsequently after 3 months. The samples of plastic automobile components were transported in the car in the period between the two analyses. The car was used in normal operation. It simulated the actual plastic environment, where these plastics are normally placed. All analyses were performed in triplicate. In total, they were analysed 18 samples of plastics and they were performed 108 analyses. Phthalic acid esters were determined by high pressure liquid chromatography.
