International audience Four trihalomethane (THM; CHCl 3 , CHBrCl 2 , CHBr 2 Cl and CHBr 3 ) and two dihalomethane (DHM; CH 2 BrCl and CH 2 Br 2 ) trace gases have been measured in air extracted from polar firn collected at the North Greenland Icecore Project (NGRIP) site. CHCl 3 was also measured in...
