"Moss bags and lichen have been examined as monitoring aids for atmospheric deposition of organic contaminants. Remote locations (Caribou Island and Agawa on Lake Superior and Kouchibouguac in New Brunswick, Canada) were used and alpha-BHC, lindane, PCBs and HCB were found at all locations. Dieldrin, the DDT residues and methoxychlor were found less frequently and endrin, heptachlor epoxide, chlordane and toxaphene were not observed at significant levels. Levels of observed substances were generally in the order: moss sheltered from the rain > exposed moss > native lichen; levels from Kouchibuguac were generally higher than those from Lake Superior"--Executive summary.
