Organochlorine pesticides (OCPs) are a type of synthetic pesticide known to be highly toxic, slow to degrade, and prone to building up in the environment. ECD is a highly sensitive detector for compounds containing electronegative atoms or functional groups (halogens, organometallics, nitrites, nitro groups), and is capable of achieving (and exceeding) the low reporting limits required for target list OC pesticides. pesticides. Complementary sampling of air, snow, sea-ice, and seawater for a range of organochlorine pesticides (OCPs) was undertaken through the early stages of respective spring sea-ice melting at coastal sites in northeast Greenland and eastern Antarctica to investigate OCP concentrations and redistribution during this time.
