  2. 36. Pesticide impact of intensive banana production on aquatic ecosystems in Costa Rica

    Author : Luisa Eugenia Castillo; Donald J Baird; Stockholms universitet; []
    Keywords : Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : A combination of chemical and biological studies demonstrated extensive surface water contamination, the occurrence of pesticides in sediments, especially near the banana plantation areas, and biological impacts.
