The Arctic has been contaminated by legacy organochlorine pesticides (OCPs) and currently used pesticides (CUPs) through atmospheric transport and oceanic currents. Here we report the time trends and air−water exchange of OCPs and CUPs from researc

The trans-continental distributions of pentachlorophenol and pentachloroanisole in pine needles indicate separate origins

Autor: Henrik Kylin, Hindrik Bouwman, Teresia Svensson, William M. J. Strachan, Sören Jensen, Robert A. Franich

The production and use of pentachlorophenol (PCP) was recently prohibited/restricted by the Stockholm Convention on persistent organic pollutants (POPs), but environmental data are few and of varying quality. We here present the first extensive datas

Methyl mercury concentrations in macroinvertebrates and fish from burned and undisturbed lakes on the Boreal Plain

Autor: Erik W. Allen, William M. J. Strachan, Weiping Zhang, Stephan Gabos, Ellie E. Prepas

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 62:1963-1977

Methyl mercury (MeHg) concentrations in macroinvertebrates and fish were compared among five lakes in burned catchments and five reference lakes on the western Canadian Boreal Plain to determine the influence of forest fire on MeHg bioaccumulation. T

Distribution of some organochlorine compounds in pine needles from Central and Northern Europe

Autor: Henrik Kylin, Anna Hellström, William M. J. Strachan, Sören Jensen

Publikováno v: Environmental Pollution. 128:29-48

Levels of selected organochlorine compounds in pine needles were measured in two sampling series. The first series collected in 1989 covered Southern Germany to Northern Scandinavia, and the second collected in 1990 covered Czechoslovakia to Estonia.

A Mass Balance Model Describing Multiyear Fate of Organochlorine Compounds in a High Arctic Lake

Autor: Paul A. Helm, D. J. Gregor, Miriam L. Diamond, R. G. Semkin, William M. J. Strachan, Camilla Teixeira

Publikováno v: Environmental Science & Technology. 36:996-1003

Data collected over a 3-year study of a high arctic watershed and lake are used to understand the fate of organochlorine compounds (OCs) and form the basis of a mass balance contaminant fate model. The model uses the fugacity/aquivalence approach to

Fluxes of semivolatile organochlorine compounds in Bow Lake, a high-altitude, glacier-fed, subalpine lake in the Canadian Rocky Mountains

Autor: Karen McDonald, Melissa Lafreniěre, Derek C. G. Muir, William M. J. Strachan, Martin Sharp, Eric Braekevelt, Jules M. Blais, David W. Schindler

Publikováno v: Limnology and Oceanography. 46:2019-2031

The fluxes of several organochlorine compounds (OCs) to and from a high-altitude lake were calculated to determine the relative contributions of rainfall, snowfall, runoff, gas absorption and volatilization, sedimentation, and outflow. Runoff inputs,

Concentrations of chlorinated pesticides were analyzed in air (biweekly 1997−1998), water, and precipitation at Lake Malawi, in southeast Africa. The pesticides in air in Senga Bay on the southwest shore of Lake Malawi were not extensively weathere

Publikováno v: Environmental Science & Technology. 34:4266-4272

Haloacetic acids (HAAs) were measured in lake water and precipitation in distinct geographical areas of Canada with the objective of determining prevailing levels and source regions of these phytotoxins. This included surface water samples from the G
