Transfer of atmospheric boron from the oceans to the continents: An investigation using precipitation waters and epiphytic lichens
International audience The variation of B concentration in atmospheric deposition was studied fromanalysis of 35 individual rain events, 17 snow packs, and 17 lichens sampled over NE North America (south from Hudson Bay) and Asia (from the coast of Bangladesh to the high Himalayas of Nepal). Rain sa...
