INTRODUCTION Phthalates are synthetic industrial compounds capable of disrupting endocrine system. Effects of phthalates depend on dosage, duration of action and stage of development of the individual, thus making the fetus, newborn, and children at puberty the most vulnerable groups. METABOLISM OF PHTHALATES: Metabolism of these compounds consists of at least two steps: hydrolysis and conjugat...

We report a new method developed for the determination of stable carbon isotopic composition of homologous alpha,omega-dicarboxylic acids and phthalic acid isolated from environmental samples such as atmospheric aerosols and snow. Dicarboxylic acids are derivatized with BF3/1-butanol to dibutyl esters, which are analyzed for the stable carbon isotopic composition using a capillary GC interfaced...

Phthalic acid esters (PAEs), as a kind of persistent organic pollutants, are classified environmental hormones, and their estrogenic effects can cause great harm to the reproductive system nervous organism. The pollution toxicological caused by this substance have received global attention, so how effectively remove PAEs in environment has become current research hotspot. This paper summarizes ...

Phthalic acid esters may be used as plasticizers in food-packaging materials that have direct contact with food. Under normal conditions of use small amounts of the plasticizers would be expected to migrate into the food. The safe use of the phthalic acid esters under these conditions is based on available toxicity data, as well as regulations which, in general, specify the maximum extractable ...

The effects, over periods from 3 days to 9 months of administration, of diets containing di-2-ethylhexyl phthalate are very similar to those observed in rats administered diets containing hypolipidemic drugs such as clofibrate. Changes occur in a characteristic order commencing with alterations in the distribution of lipid within the liver, quickly followed by proliferation of hepatic peroxisom...

JAROŠOVÁ A. (2006): Phthalic acid esters (PAEs) in the food chain. Czech J. Food Sci., 24: 223–231. Phthalic acid esters (PAEs) rank among the primary risk pollutants and their adverse effects may endanger the environmental balance and affect the ontogenetic development of live organisms and their body functions. Therefore, the aim of this study was to monitor the occurrence of PAEs in packagin...
