摘要：

We compare total mercury (Hg-T) loading and methylmercury (MeHg) accumulation in streams and lakes from an urbanized area (Boston, Massachusetts) to rural regions of southern New Hampshire and Maine. The maximum Hg-T loading, as indicated by Hg-T atmospheric deposition, Hg-T emissions, and sediment Hg-T concentrations, did not coincide with maximum MeHg concentrations in fish. Urbanized ecosystems were areas of high Hg-T loading but had low MeHg concentrations in fish. Controls on MeHg production and accumulation appeared to be related primarily to Hg-T loading in undeveloped areas, while ecosystem sensitivity to MeHg formation appeared to be more important in regulating accumulation of MeHg in the urban area.
