What is it about?
Contamination of waders breeding in the Arctic. Seven eggs from four clutches of grey plovers (Pluvialis squatarola) breeding in the Lena Delta, Sakha Republic, Yakutia, in 1997 were analysed for persistent organochlorines and mercury. Contaminaüon levels were low and within the same ränge äs found in eggs from waders (Charadriifarmes) breeding in north-west Europe. One exception was SHCH, averaging 99.2 ng g fresh egg mass, a level about ten times higher than in wader eggs from north-west Europe. /?-HCH accounted for 98% of the total HCH concentration. There are indicadons that the pesticide levels may reflect former local use. SPCB level (57.0 ng g- , 62 congeners) and mercury concentration (68.7 ngg-) can be considered low.
