    Abstract : Popular Abstract in Swedish Bekämpningsmedel och algblomningar - finns det någon koppling? Inom det konventionella jordbruket används idag regelmässigt stora mängder bekämpnings-medel, bara i sverige spreds under år 2001 mer än 1700 ton kemiska bekämpnings-medel på åkrarna. Ett stort problem med användandet av dessa ämnen är risken att de sprids och förorenar den intilliggande naturen. READ MORE

    Abstract : In this thesis, brackish and freshwater littoral model communities (microcosms) of varying size and complexity were used to study the effects of brominated flame retardants (BFRs) and pesticides. The brackish water microcosms consisted of natural water, sediment and associated organisms, while the larger freshwater microcosms also contained submersed macrophytes (Elodea canadensis). READ MORE
