Download or read book Behaviors of Trace Metals in Environment written by Hui Zhang and published by Springer. This book was released on 2019-05-03 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the behavior and impact of trace metals in the environment by studying typical cases from China such as the Hetao Area of the Yellow River, Shanghai, and Nanjing. Based on samples and experiments on the behavior of pollutants, it systematically discusses the regulation of trace metals’ distribution, accumulation, and migration, associated with the cause of formation demonstration. The author subsequently uses the acquired data to review the evolving trend of trace metal behaviors in natural systems (river or lake water, sediments, and soils), develops suggestions for the prevention of their negative effects, and devise treatments. Moreover, he proposes solutions to difficult research issues such as trace metal speciation extraction, and an analysis, along with operational procedures. Given its scope, the book will provide a valuable guide for researchers and engineers in relevant disciplines of the environmental sciences and engineering, and for environmental policymakers to consult in practices.

Book excerpt: The book presents some of the findings of research into China’s water quality criteria for toxic pollutants, including heavy metals, PAHs and emerging pollutant. Water quality criteria (WQC) are the scientific basis for establishing water quality standards (WQSs). For a long time, the study of WQC in China has been neglected, so that almost all of China’s WQSs were developed based on foreign WQC. This book provides valuable information for environmental management and revision of WQSs. It has been written for researchers and graduate students in the field of environmental science and risk assessors for chemical and pollutants etc. Dr. Zhen-guang Yan is an Associate Professor at the Chinese Research Academy of Environmental Sciences. Dr. Zhengtao Liu is a Professor at the Chinese Research Academy of Environmental Sciences.

Book excerpt: Master's Thesis from the year 2012 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, , language: English, abstract: The effect of leachate seepage from a landfill site on the quality of an urban river, Densu, that is the one of the main sources of water abstracted for treatment for most residents in the Accra Metropolitan area was determined by measuring the levels of heavy metals (As, Pb, Hg, and Cd) in the seepage and in the river itself using Atomic Absorption Spectrometry methods. Heavy metal concentration upstream before leachate contamination was low and within WHO limits. The mean concentrations of arsenic, lead, mercury and cadmium were 0.026mg/l, 0.957mg/l, 0.025mg/l and 0.005mg/l, respectively in the leachate. Mean heavy metal concentration, two hundred metres downstream from the leachate discharge point (where water is drawn for domestic and drinking purpose) was 0.008mg/l for arsenic, 0.393mg/l for lead, 0.001mg/l for mercury while cadmium was not detected. Lead exceeded the WHO acceptable limit of 0.01mg/l for drinking water. Mean levels in the corresponding sediment samples were 0.015mg/kg for arsenic,

Abstract: Deep Bay is located in the northwestern coast of Hong Kong (HK), where brackish water from the Pearl River Estuary meets and interacts with fresh water from Shenzhen River and Yuen Long Creek. A review of published material in this study indicates rapid economic and industrial developments can be found in Hong Kong and Pearl River Delta (PRD) region in the last 60years, which would have contaminated the sediment in Deep Bay with heavy metals. To examine the nature of metal contamination history, two 2m-long sediment cores are collected from the mud flat of Deep Bay, and the chemical and physical properties of the sediment sequence analyzed. Small disturbance of sediment profile is observed by the fluctuation of 210Pb signal, and constant rate of supply (CRS) model is applied for the calculation of sedimentation rate which is estimated to be 1.82cm/year.137Cs dating resolves two peaks for the radionuclide at 28cm and 109cm, as well as the onset of excessive 137Cs activity at 135cm, which are connected to the Chernobyl accident in 1986 and the banning and beginning of atmospheric testing of nuclear weapons in 1963 and 1950 respectively. Particle size analysis shows the core sediments are predominantly silt (4-64μm) and clay(DOI: 10.5353/th_b5053424 Subjects: Contaminated sediments - China - Hong Kong Heavy metals - Environmental aspects - China - Hong Kong

This book was released on 2009 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Pearl River Delta is the socio-economic hub of southern China. The region has experienced rapid industrialisation, particularly since the start of the Chinese Reform Programme in 1979. This rapid industrial development has been coupled with increased pressures on the natural environment environment from pollution and waste associated with this development. These pollutants are transported from within the Pearl River catchment and deposited in sediments of the Pearl River Estuary (PRE). Geospatial and principal component analysis of the heavy metals Al, Cd, Co, Cr, Cu, Fe, Ni, Pb, Ti and Zn in surface sediments identifies four patterns of spatial distribution that are attributed to three separate heavy metal sources. After normalisation for the effects of the fine particle size affinity, the same spatial distribution patterns remain, but with much less localised variability. Anticlockwise estuarine circulation and the interaction of marine and river water, where distributaries of the North and West Rivers enter the PRE, account for higher concentrations of all metals except Al in the west of the estuary. Pb and Zn are identified as the heavy metals displaying significant enrichment from non-natural sources. Their concentrations which peak at 168 and 699.9mg/Kg respectively along the North River, are found to be associated with higher baseline concentrations resulting from the erosion of metal sulphide bearing carbonates within the catchment. These higher baseline concentrations have then been further enriched by Galena (PbS) and Sphalerite (ZnS) mining operations, atmospheric deposition from fossil fuel burning and some point sources associated with urban and industrial waste. Temporal analysis of heavy metals and stable Pb isotope variability again highlights Pb and Zn as being significantly enriched from anthropogenic sources, with maximum enrichment factors of 2.6 and 1.8 respectively. The enrichment of these two metals is shown to begin in the 1950s and acceleration of their enrichment in the early 1990s. This second phase of enrichment in the 1990s is also associated with slight enrichment of Cr, Cu and Ni that is also attributed to anthropogenic sources.
