The uptake of metals from food and water sources by insects is thought to be additive. For a
given metal, the proportions taken up from water and food will depend both on the …

The available literature on heavy metal bioaccumulation by freshwater macro-invertebrates
has been analysed. A very uneven data distribution was found. Ephemeroptera and Diptera …

From 1997 until 1999 the extent and the ecological effects of zinc, copper, lead, and
cadmium pollution were studied in different reaches of the South American Pilcomayo River …

This chapter examines community responses of benthic organisms to heavy metals in
streams. Descriptive approaches, such as routine biomonitoring of community structure and …

Trace element bioaccumulation was studied in immature benthic insects from two
contaminated river systems to develop these animals as bioindicators. In one river, Cu, Cd …

Aluminum (Al) is the third most common mineral and the most common metal in Earth's crust,
accounting for approximately 8.1% of the crust by weight. Thus, it cannot be considered a …

This paper reviews the literature to determine if lowered water pH (a) affects metal
bioaccumulation in freshwater invertebrates,(b) enhances the toxicity of a given metal, and …

Abstract Cadmium, Zn, Pb and Cu uptake and effects in larvae of Chironomus riparius
(Meigen) were studied in an integrated laboratory investigation, in which metal analyses in …

Aquatic micropollutants can be transported to terrestrial systems and their consumers by
emergent aquatic insects. However, micropollutants, such as metals, may also affect the flux …
