ATMOSPHERIC DEPOSITION OF CURRENT-USE AND HISTORIC-USE PESTICIDES IN SNOW AT NATIONAL PARKS IN THE WESTERN UNITED STATES
The United States (U.S.) National Park Service has initiated research on the atmospheric deposition and fate of semi-volatile organic compounds in its alpine, sub-Arctic, and Arctic ecosystems in the Western U.S. Results for the analysis of pesticides in seasonal snowpack samples collected in spring...

From a target analyte list of 47 pesticides and degradation products, the most frequently detected current-use pesticides were dacthal, chlorpyrifos, endosulfan, and -hexachlorocyclohexane, whereas the most frequently detected historic-use pesticides were dieldrin, -hexachlorocyclohexane, chlordane, and hexachlorobenzene.
