Effluents from electroplating industries contain large amounts of heavy metals. These must be treated before discharge into aquatic systems to prevent serious environmental damage. The yeast Saccharomyces cerevisiae, a byproduct of fermentation industries, combines high metal accumulation with low costs. However, an article in issue 4 of Chemical Speciation and Bioavailability explains how the fluoride anions present in the effluent may preclude bioremediation of chromium(III) by yeast cells.

With continuing population growth and rapid economic development of China, the environmental quality of rural soil is becoming more and more important with regard to human health. A study reported in Chemical Speciation and Bioavailability assesses the spatial changes of Cd and Zn in the surface soil in the Henan Province cultivated area.

Lead, a toxic heavy metal, is found in high concentrations in shooting range soils due to the abrasion and weathering of bullets accumulated over the years.  This can adversely impact the environment through leaching into groundwater or runoff into streams, lakes and rivers. In the latest issue of Chemical Speciation and Bioavailability a group from the Soil and Water Science Department, University of Florida describe how the conversion of metallic lead to carbonates may aid natural attenuation of lead in shooting range soils.

Environmental concerns throughout the world are always featured in Chemical Speciation and Bioavailability. Issue 1 of 2011 contains two articles about the contamination that affected communities in the Niger Delta region of Nigeria following a crude oil spillage. The inorganic and organic pollutants in soil, sediments and ground water have negative consequences for all ecosystems and subsequently for human health.

Relatively little or no information is available regarding the speciation of metals in soils that have been significantly affected by crude oil spillage in the Niger Delta.

Crude oil contaminated sites represent a major challenge in many communities in the Niger Delta region of Nigeria. Local soil contamination, mainly associated with operations and activities of the petroleum industry, is an actual and relevant environmental priority in the area.
