Legacy persistent organic pollutants and chemicals of emerging concern in Sweden : from indoor environments to remote areas
Bulk atmospheric deposition samples were taken every two months for a year in 2009-2010 at two sites in northern Sweden and analyzed for a suite of legacy and emerging persistent organic chemicals including legacy organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated dip...
