Effects of heavy metal pollution on soil macrofauna in a grassland of Northern France

Influence of [S, S]-EDDS on Phytoextraction of Copper and Zinc byElsholtzia SplendensFrom Metal-Contaminated Soil

“…The major sources of Cu release to the terrestrial environment are mining operations, agriculture, solid waste, and sludge from wastewater treatment works (IPCS, 1998). Zn can also show toxicity when present at high concentrations (Kamal et al, 2004;Nahmani and Lavelle, 2002).…”

Novel Approaches to Bioindication of Heavy Metals in Soils Contaminated by Oil Shale Wastes

“…According to [1] accumulation of hazardous substances by several organisms has become an important component of bioindication as this allows the presence of low levels of chemicals in the environment to be identified and quantified. The earthworms are one of the best bioindicators of trace metals amongst soil invertebrates because they are able to accumulate metal ions in the body tissues [3,14,30]. It is important to study the individuals of different species separately and to know ecological characteristics of species and soil characteristics as different species have several different mechanisms of accumulation and excretion of metal ions [27,29].…”

Heavy Metal Pollution as a Biodiversity Threat

“…The study by Jung et al demonstrated that although the Shannon-Wiener diversity index values were similar between contaminated and less contaminated sites (Pb, Cd) for six different spider families, the abundance of the Linyphiidae family was correlated with metal concentrations in soils and enabled the discrimination between contaminated and less contaminated sites [12]. In contrast, others analyzed the community of the Phyla Annelida and Arthopoda, they found that absolute and relative abundances of all the organisms was lower in the most polluted sites [26]. Specifically, the earthworm species A. caliginosa had higher densities in non-polluted sites and was absent in polluted sites, on the contrary, the larvae of the coleopteran Hoplinae predominated in highly Zn polluted sites.…”

“…Among the few studies conducted in terrestrial ecosystems, insect communities are the point of interest [11,12]. In these type of studies bioaccumulation levels are analyzed in different invertebrate groups and the relationship between bioaccumulation levels and community effects (mainly species richness and composition) is examined.…”
