Environmental monitoring using malformed embryos of the amphipod Monoporeia affinis
Abstract
Reproduction variables of Monoporeia affinis, such as embryonic malformation were confirmed as the most sensitive variable, when soft bottom microcosms were exposed to metals such as cadmium and lead, arsenic, organic compounds such as 4,5,6 trichloroguaiacol, contaminated sediment from areas impacted by heavy metals and pulp mill effluents. The effects were demonstrated also in low concentrations that did not significantly affect the meiofauna community. The microcosm test-system with high ecological realism could offer a possibility to translate laboratory results to the natural environments. Field surveys outside different types of pulp mills and metal works on the coast of the Gulf of Bothnia have confirmed the laboratory results. Significantly higher levels of malformed embryos of Monoporeia affinis were demonstrated in the impacted areas in comparison with reference areas. The reproduction variables of Monoporeia affinis have been used in the national environmental monitoring program during two years and results indicated possibilities to distinguish between effects of xenobiotica and secondary eutrophication effects, such as unsaturated oxygen condition and occurrence of sulfides, which resulted in increased frequencies of dead eggs but not affected the frequencies of malformed eggs and embryos.
