  3. 7. Prospective and longitudinal human studies of lead and cadmium exposure and the kidney

    Författare :Johan Nilsson Sommar; Ingvar A Bergdahl; Max Petzold; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cadmium; end-stage renal disease; kidney; lead; longitudinal; matched case-control; mixed effects; prospective; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Cadmium and lead accumulate in humans and can have toxic effects. Exposure to cadmium is well known to cause kidney damage. Cadmium binds to metallothioneins, proteins that play a role in cadmium transport. LÄS MER

  5. 9. Long-term changes of mercury, lead and persistent organic pollutants in arctic environments

    Författare :Carola Lindeberg; Ingemar Renberg; Mats Tysklind; Ove Emteryd; Edvard Karlsson; Per Jonsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lake sediment; time trends; chlordane; hexachlorobenzene; mercury; lead; soil; climate changes; Arctic; Greenland; Sweden; Swedish mountains; PCB; PBDE; pesticides; Earth sciences; Geovetenskap;

    Sammanfattning : The Arctic represents a huge area with poor infrastructure contributing to limited possibilities to establish monitoring and research programs. From the investigations that have been performed we know that the arctic environment is affected by anthropogenic emissions from lower latitudes, but knowledge about underlying transport processes, the arctic pollution extent and the rates of changes are limited.

    Sammanfattning : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies.
