Abstract
Phthalates are the most used plasticizers in industrial products. They have low
toxicity, but have frequently been an object of environmental concern because of
their worldwide distribution in ecosystems. Their presence and concentrations in
the environment indicate a region's industrialization degree. Phthalates have also
been investigated as an endocrine disruptor, especially in the reproductive
system. This work studies phthalate contamination levels in tap water from
thirteen different regions of the city of Rio de Janeiro. The samples were solid
phase extracted in Qg disks and the obtained acetone extracts were analysed by
gas chromatography with electron capture detection. Extraction recoveries were
calculated using surrogate standards, diphenyl phthalate and di- isophenyl
phthalate, and provided value
