Perchlorate (ClO4−) is harmful to human health, and knowledge on the levels and sources of natural ClO4− in different environments remains rather limited. Here, we investigate ClO4− in aerosol samples collected along a cross-hemisphere ship cruise between China and Antarctica and on a traverse betwe...
