Abstract:

210Pb dating for stratigraph in penguin dropping amended soil has been measured,and organochlorine pesticides content in dropping amended soil stratigraph and penguin eggs by GC-ECD. Maximal concentration of organochlorine pesticides in stratigraph appear in surface: PCBs are 0.92 ng/g,HCHs 0.42 ng/g,and DDTs 0.70 ng/g. Comparing with non-dropping amended soil,this research showed that input of PCBs and OCPs in dropping amended soil stratigraph (nidation and dejecta) with activity of birds were much more than that with no birds. ∑PCB in penguin eggs are 0.4—10.2 ng/g,∑DDT 2.4—10.3 ng/g,HCB 0.1—9.4 ng/g,and ∑HCH 0.1—0.5 ng/g,while total accumulation levels ordinally are: ∑PCB>∑DDT>HCB>∑HCH.
