Download or read book Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems written by St ́ephane Gu ́edron and published by Mdpi AG. This book was released on 2021-11-09 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue aims to provide new insights into the issue of the mercury contamination of terrestrial and aquatic ecosystems. This ubiquitous contaminant has been used by humans for many years, resulting in global contamination. When this toxic contaminant is converted to methylmercury, it accumulates in trophic chains, which is a major issue for wildlife and human health. The nine articles contained within this Special Issue on ''Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems'' endeavour to identify the historical evolution of Hg and MeHg levels in aquatic environments, and to evaluate the impact of current and historical human activities, such as mining, climate change, and soil erosion, on receptor ecosystems and food chains.

Download or read book Mercury from Gold and Silver Mining written by Luiz D.de Lacerda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its inherent characteristics, mercury contamination from gold mining is a major environmental problem compared to past mercury contamination from industrial point sources. The worsening of social-economical conditions and increasing gold prices in the late 1970s resulted in a new rush for gold by individual entrepreneurs for whom Hg amalgamation is a cheap and easily carried out operation. Even after the present-day mining areas are exhausted, the mercury left behind will remain part of the biochemical cycle of the tropical forest. This book reviews the current information on mercury from gold mining, its cycling in the environment and its long-term ecotoxicological impact. The book is illustrated with numerous diagrams and photographs.

Download or read book Mercury from Gold and Silver Mining written by Luiz Drude de Lacerda and published by Springer Science & Business Media. This book was released on 1998 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury contamination from gold mining is a major environmental problem. Deteriorating socio-economic conditions and increasing gold prices in the late 1970s resulted in a new rush for gold by individual entrepreneurs. Even after the present-day mining areas are exhausted, the mercury left behind will remain part of the biochemical cycle of the forest for years to come. This volume provides the latest information on mercury contamination from gold mining, including numerous illustrations, high-quality diagrams, and photographs.

Available in PDF, EPUB and Kindle. Book excerpt: In order to evaluate ultra-trace concentrations of MeHg in various matrices, a new HPLC-CV-AFS method was developed. To achieve exceptionally low limits of detection (0.4 ng/L) Hg species are first trapped on the preconcentration column with possibility of on-line preconcentration of up to 200 mL of sample. Then trapped Hg species are eluted and separated on HPLC column and detected by CV-AFS. The robustness of the method was validated with 6 certified reference materials (DOLT-2, DOLT-4, DORM-3, TORT-2, IAEA-140/TM, ERM®-CC580), which showed recovery in the range of 88 – 104%. Moreover, a comparison between MeHg concentrations in the biological tissues carried out by species-specific isotope dilution gas chromatography inductively coupled plasma mass spectrometry and HPLC-CV-AFS showed very good correlation (R2 = 0.97) what is further advocating the reliability of the newly developed method.

Available in PDF, EPUB and Kindle. Book excerpt: Assisted Phytoremediaion covers a wide range of uses of plants for remediation of environmental pollutants. It includes coverage of such techniques as root engineering, transgenic plants, increasing the biomass, use of genetic engineering and genome editing technology for rapid phytoremediation of pollutants. In order to improve the efficiency of plant remediation, genetic engineering plays a vital role in the overexpression of genes or gene clusters, which are responsible for degradation and uptake of pollutants. The book presents state-of-the-art techniques of assisted phytoremediation to better manage soil and water pollution in large amounts. This book is a valuable resource for researchers, students, and engineers in environmental science and bioengineering, with case studies and state-of-the-art research from eminent global scientists. This book serves as an excellent basis from which scientific knowledge can grow and widen in the field of environmental remediation. - Provides a clear picture of how to design, tune, and implement assisted phytoremediation techniques - Offers a comprehensive analysis of current perspective and state-of-the-art applications of assisted phytoremediation - Introduces the potential of genetic engineering as a rapid, cost-effective technology for environmental remediation using plants
