Resumo
Persistent Organic Pollutants (POPs) are toxic organic compounds resistant to environmental degradation.
Besides, POPs bioaccumulate with potential significant impacts on human health and the environment. The
Global Monitoring Plan (GMP) under the Stockholm Convention on POPs is a program that enables collection
of comparable monitoring data from all regions of the world to assess the effectiveness in minimizing human
and environmental exposure to POPs. The scope of this work is to develop and validate a method for the
extraction and determination of POPs in sediments collected at Billings dam locate in São Paulo Metropolitan
City. The compounds studied in this work are: Aldrin (C12H8Cl6), DDD (C14H10Cl4), DDE (C14H8Cll4), DDT
(C14H9Cl5), Dieldrin (C12H8Cl6O), Endrin (C12H8Cl6O) and Heptachlor (C10H5Cl7). This work use the
QuEChERS extraction method (Quick, Easy, Cheap, Effective, Rugged, and Safe) for sediment samples and the
analysis of the compounds were carried out by gas chromatography with the electron capture detector
(GC/ECD). The ECD detector ionizes the analytes by the beta particles from the nuclide sources 63Ni within
carrier gas N2. The electrons produced in this process are collected, create an amplified current, and generating
the chromatographic peak. The recovery of this method obtained values between 57% and 65% and the
Relative Standard Deviation (RSD) values are between 1 and 4%. Details of the analytical method beside
quantitative analyses data are presented in this work.
