12. Metal Speciation and Toxicity in Urban River Sediments
Sammanfattning : Metal transport, speciation and toxicity were studied in urban runoff and receiving urban river systems. Sediments were recognised as an important environmental compartment for metals. LÄS MER

14. Boreal Lake Sediments as Sources and Sinks of Carbon
Sammanfattning : Inland waters process large amounts of organic carbon, contributing to CO2 and CH4 emissions, as well as storing organic carbon (OC) over geological timescales. Recently, it has been shown that the magnitude of these processes is of global significance. LÄS MER
15. Catching Mercury : Mercury in Lake Vänern and Swedish catchments
Sammanfattning : Vänern och dess sediment har under 1900-talet varit en av Sveriges mest kvicksilver (Hg) kontaminerade miljöer. 47 sedimentprofiler tagna 2001 analyserades for total Hg och temporala och spatiala mönster påvisades. Av den direkta Hg tillförseln 1918-2001 återfinns c:a 30 ton i bottensedimenten. LÄS MER
