Sub project #6:
Assessing Persistent and Bioaccumulative Compounds in wildlife from the YRD
Environmental contamination by PBCs is a result of modern life that has led to serious effects for wildlife, particularly species at high trophic levels of birds and mammals. This has led to adoption of the Stockholm Convention in 2001 on persistent organic pollutants (POPs), a convention including more than 20 chemicals or chemical classes (e.g. PCBs, PBDEs). China has a high production of chemicals in general to be used as pharmaceuticals, pesticides and in materials and goods among which are novel chemicals. For chemicals being both persistent and bioaccumulative it is reasonable to explore their presence in wildlife.
The aims of the subproject #6 are:
- To assess the occurrence of Persistent and Bioaccumulative Compounds in wildlife
- To initiate synthesis of reference standards
- To identify the contaminants and to determine their concentrations in the species analysed
- To identify any potential species for research monitoring
Data have been accumulated identifying chlorinated paraffins (CPs) as major contaminants in several species but also numerous other substances were identified and quantified. Also some hitherto non-identified contaminants have been detected.
