Concentration of metals in various larval stages of four Ephemeroptera species.

摘要: Most of the surface waters in southern part Poland have received considerable amounts wastewaters which can be biologically active, toxic or a potential for bioconcentration. Field investigations shown that heavy metals often reduce abundance and diversity aquatic insects. Mayfly larvae been known to more sensitive than other groups insets. This investigation provided an opportunity assess bioconcentration cadmium, copper, lead zinc various stages mayflies Ephemera danica Muller, vulgata (L.), Leptophlebia vespertina (L.) Baetis vernus Curt. collected from stream Lane Bloto (South Poland) water quality was strongly affected by air pollution.
