Established in 1970, the PbZn symposium series is considered the leading international technical forum for the lead and zinc processing industries. The PbZn 2020 volume addresses all aspects of current processing technologies for primary and secondary lead and zinc, as well as emerging technologies for both metals.

Hailian Chen’s pioneering study presents the first comprehensive history of Chinese zinc—an essential base metal used to produce brass and coin and a global commodity—over the long eighteenth century. Zinc, she argues, played a far greater role in the Qing economy and in integrating China into an emerging global economy, than has previously been recognized. Using commodity chain analysis and exploring over 5,800 items of archival documents, Chen demonstrates how this metal was produced, transported, traded, and consumed by human agents. Situating the zinc story within the human-environment framework, this book covers a broad and interdisciplinary range of political economy, material culture, environment, technology, and society, which casts new light on our understanding of early modern China.

Achieving the goals and objectives of sustainable development requires better information about the consequences of proposed actions. Partial information accounts for many failed efforts in the past. The financial implications for the proponent of the projects have often been more thoroughly analyzed than the implications for other actors. The impacts on biological diversity, or on the social fabric of local communities, have often been ignored. Decisi- makers may also focus more on the short-term consequences instead of long- term impacts, creating negative unintended consequences. It is clear that better decision-making processes are needed. Making better decisions requires identifying, obtaining, synthesizing and acting on larger and more diverse data sets, including information that has previously been overlooked in development decisions. The good news is that better processes are being developed and are becoming available. If the goal is to reach decisions that are broadly understood and accepted, affected communities need to be consulted. Early public participation in defining problems is a prerequisite to effective decision-making. There is no universal formula or checklist of information applicable to every proposed project. The scope of information required should not be determined from the start by small cadres of experts. It is unlikely that any individual or small group processes all of the expertise to achieve the kind of profound int- disciplinary synthesis that is needed.

This third edition of the book has been completely re-written, providing a wider scope and enhanced coverage. It covers the general principles of the natural occurrence, pollution sources, chemical analysis, soil chemical behaviour and soil-plant-animal relationships of heavy metals and metalloids, followed by a detailed coverage of 21 individual elements, including: antimony, arsenic, barium, cadmium, chromium, cobalt, copper, gold, lead, manganese, mercury, molybdenum, nickel, selenium, silver, thallium, tin, tungsten, uranium, vanadium and zinc. The book is highly relevant for those involved in environmental science, soil science, geochemistry, agronomy, environmental health, and environmental engineering, including specialists responsible for the management and clean-up of contaminated land.

Summarizes information on all aspects of metallic zinc and gives references to additional source material, including major books and reviews. At the heart of the reference are 16 chapters that cover coatings and electrochemical protection of steel by zinc. Other chapters address: occurrence and prod
