Toxicity of heavy metals to Asellus aquaticus (L.) (Crustacea, Isopoda)

Abstract

Effects of heavy metals on the isopod Asellus aquaticus (L.) are studied by static toxicity tests. Results demonstrate that the species is sensitive to Cd + 2, Cr + 6, Cu + 2, Fe + 3, Hg + 2, Ni + 2, Pb + 2 and Zn + 2, but the toxicity of each metal is different. Differences are also found between adults and between adults and juveniles. The comparative analysis of all data on the toxicity has been performed on the concentrations of metal ions and not on metal compound concentrations.Criteria for establishing water quality in order to guarantee protection of the environment are discussed.

Evaluation of Nickel–Zinc Interactions by Means of Bioassays with Amphibian Embryos

“…On the other hand, a high concentration of Zn a!ect reproduction and survival in Daphnia magna (Munzinger and Monicelli, 1991), and it has e!ects on food absorption (Naylor et al, 1990), survival rate (Migliore and De Nicola Giudici, 1990), "tness, reproduction, and longevity (Beyer and Anderson, 1985) in a variety of other invertebrates,. In Bufo arenarum embryos concentrations as high as 130 mg Zn>/L had no adverse e!ects (Herkovits and Helguero, 1998).…”

A new method for early assessment of effects of exposing two non-target crustacean species, Asellus aquaticus and Gammarus fossarum, to pesticides, a laboratory study

“…Toxicology and Industrial Health 26 (4) inhabit (Migliore and De Nicola Giudici, 1990). Furthermore, the presence of some toxic compounds can be found in their tissues long after exposure, thus outside influences can be monitored and spotted after incidents (Plenet, 1995;Van Gestel and Brummelen, 1996).…”

Heavy metals affect the circulating haemocyte number in the shrimp Palaemon elegans

“…Heavy metals were chosen as suitable pollutants because they are widespread environmental contaminants, from either natural or anthropogenic sources, and are widely believed to be a threat to the health and survival of many marine or aquatic animals, including crustaceans (Ahsanullah et al, 1981;Migliore & de Nicola Giudici, 1990). However, there are conflicting reports on their e#ects on haemocyte number in crustaceans.…”
