This book reviews the progresses and achievements made in the past 20 years of research on soil pollution and remediation in China, and presents 50 review and research articles from all over China, including Hong Kong and Taiwan. The authors include scientists, engineers, entrepreneurs and managers from 26 universities, 18 institutes, 4 leading enterprises and 2 government environmental protection departments. The contents cover fundamental research on soil pollution and remediation, technical development, project demonstration, policy and governance. The polluted soil/site types include farmland, industrial sites, mining areas and oilfields, with heavy metals (cadmium, arsenic, copper, chromium, mercury, lead, zinc, nickel, etc.), organic pollutants (PAHs, PCBs, organochlorine pesticides, phthalate esters, halogenated hydrocarbons, etc.), and metal–organic mixed pollutants. The remediation techniques mainly include physical and chemical remediation (thermal desorption, soil vapor extraction, in situ advanced chemical oxidation, solidification and stabilization), phytoremediation (phytostabilization, phytoextraction by hyperaccumulators, phyto-prevention by low accumulation plants), bioremediation (microbial adsorption and immobilization, microbial degradation, microbe-enhanced phytoremediation), and combined remediation merging multiple technologies. The governance and policy section mainly explores laws and regulations, criteria and standards, financial guarantees and the industrial market for soil environment and pollution prevention.

The papers in this SI present valuable results in the topics of soils, sediments, and water contamination according to the consideration of ecological and health risk. They also point out open questions and possible avenues for future research. Biochar application can benefit both soil conservation and contamination, but further research should be conducted to investigate whether these positive effects can be extended to the field scale. Similar to biochar, scale-up design will be helpful for thin-layer capping in in situ sediments using mixed active amendments. Both physiochemical analysis and bioassays mutually supported the evaluation results of river water quality. However, we need better approaches and policies for management to prevent further contamination from the discharge of untreated industrial and domestic waste into this aquatic ecosystem. The use of microorganisms to eliminate antibiotics is a promising strategy, but future work should verify the biodegradation ability of antibiotic-degrading bacteria in wastewater treatment plants.

This book presents an intensive study on the biogeochemical cycle of mercury in a river-reservoir system in Wujiang River Basin, the upper branch of the Yangtze River. Six reservoirs located in the mainstream of the Wujiang River and their corresponding inflow/outflow rivers were selected for inclusion in this study, which was conducted by researchers from the Institute of Geochemistry, Chinese Academy of Sciences. The concentration and distribution of Hg in reservoirs (the water column, sediment, sediment pore water), inflow/outflow rivers of reservoirs, and wet deposition in Wujiang River Basin were systematically investigated, and measurements were taken of the water/air exchange flux of gaseous elemental mercury (GEM). On the basis of the data gathered, a detailed mass balance of total mercury (THg) and methylmercury (MeHg) in the six reservoirs was developed. In addition, the book identifies the primary factors controlling Hg methylation in the river-reservoir system in Wujiang River Basin. The accumulation and bio-magnification of Hg species within food chains in reservoirs and human health risk of MeHg exposure through fish consumption are also included in this book.

The Nordic Council of Ministers have recognized the need to compile the knowledge of sediment remediation strategies and to evaluate different remediation approaches. The objective of this report is to give a status of regulatory framework and sediment management within selected Nordic countries (Norway, Sweden, Finland and Denmark). In addition, the report gives a short overview of international knowledge on remediation approaches, techniques, and materials. Governance and regulatory instruments in dealing with contaminated sediments vary between countries. Of the countries presented, only Norwegian environmental authorities have implemented a national strategy for remediation of marine contaminated sediments. A Nordic database of clean-up projects and long-term monitoring would improve the exchange of knowledge between the Nordic countries.

Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.

This book discusses bioavailability concepts and methods, summarizing the current knowledge on bioavailability science, as well as possible pathways for integrating bioavailability into risk assessment and the regulation of organic chemicals. Divided into 5 parts, it begins with an overview of chemical distribution in soil and sediment, as well as the bioavailability and bioaccumulation of chemicals in plants, soil, invertebrates and vertebrates (including humans). It then focuses on the impact of sorption processes and reviews bioavailability measurement methods. The closing chapters discuss the impact of bioavailability studies on chemical risk assessment, and highlights further research needs. Written by a multi-disciplinary team of authors, it is an essential resource for scientists in academia and industry, students, as well as for authorities.

Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.
