Endemic fluorosis is caused by excessive intake of fluorine in drinking water, air, food, tea and other media in a specific natural environment for a long time, which involves at least 25 countries, such as China, India, Vietnam, Iran, Egypt, Mexico, Argentina and influences more than 200 million of population. China and India are the countries with the most extensive endemic fluorosis and the most serious damages. There are three main intake sources of endemic fluorosis, e.g., drinking water, coal-burning pollution and drinking tea. Coal-burning type of endemic fluorosis was established in Guizhou Province of China in 1970’s. The residents in the areas used indoor stoves with no flue to burn coals with high content of fluoride to bake grains in the autumn and heat in the winter. This results in excessive intake of fluorine and then leads chronic poisoning. It has been confirmed that 13 provinces of China with 34.3 million of population are influenced by this type of fluorosis with severe injuries to most organs of human body. The content of this book covers the epidemiology, pathological changes, molecular pathogenesis and clinical treatments of the disease. This book is a suitable reference for the researchers and graduate students in this field, which is helpful to improve the understanding of this disease and to take preventive measures.

‘Coal’ and ‘China’ to some extent have become synonymous. China is by far the largest user of coal in the world. In 2016, coal production in China amounted to 3.21 billion tons, about half of the total global coal production. Coal consumption accounts for more than 65% of primary energy consumption in China. The Chinese coal industry greatly contributes to the economic development in China, the second largest economy in the world. However, periodically, ubiquitous images of smog blanketing major Chinese cities are viewed all over the world. Coal combustion is one of the important contributors to smog, which is considered to be a major environmental and human health problem for China and other countries. News stories also highlight the periodic coal mine disasters that kill hundreds of Chinese coal miners annually. The need to address these and other human health, environmental, and mine safety issues and to maximize resource recovery and use justifies a vigorous coal research effort. This book brings together experts on almost every aspect of coal geology, coal production, composition and use of the coal and its by-products, and coal’s environmental and human health impacts. The chapters in this book were originally published in a special issue of the International Geology Review.

The congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for arsenic research aimed at practical solutions of problems with considerable social impact, as well as focusing on cutting edge and breakthrough research in physical, chemical, toxicological, medical and other specific issues on arsenic on a broader environmental realm. The congress "Arsenic in the Environment" was first organized in Mexico City (As 2006) followed by As 2008 in Valencia, Spain and As 2010 in Tainan, Taiwan. The 4th International Congress As 2012 was held in Cairns, Australia from July 22-27, 2012 entitled Understanding the Geological and Medical Interface of Arsenic. The session topics comprised: 1. Geology and hydrogeology of arsenic; 2. Medical and health issues of arsenic; 3. Remediation and policy; 4. Analytical methods for arsenic; and 5. Special topics on "Risk assessment of arsenic from mining", "Geomicrobiology of arsenic", "Geothermal arsenic", "Rice arsenic and health perspectives", "Sustainable mitigation of arsenic: from field trials to policy implications", and "Biogeochemical processes of high arsenic groundwater in inland basins" Hosting this congress in Australia was welcome and valued by the local scientific communities. Australia is a mineral rich country where mining has generated significant economic benefit to its people. Unfortunately historical mining for base metals, gold and arsenic had led to environmental contamination of arsenic. Locally produced arsenical compounds were widely used as pesticides and in timber preservation. It is known that there are several thousands of cattle- and sheep-dip sites contaminated with arsenic in Australia. However, commonly observed symptoms of chronic arsenic poisonings such as those found in endemic-blackfoot areas are seemingly absent from these types of environmental contamination due to good quality of potable water supply. Does this fall in the classic argument of "the dose makes the poison"? This congress theme of "understanding the geological and medical interface of arsenic" will advance our knowledge in minimising the risk posted by this so-called number one prioritised contaminant – arsenic.

This book describes in detail various aspects of fluoride toxicity in animals. Animals, like human beings, suffer from the toxic effects of excess fluoride intake. They show pathological changes in their teeth and bone, together with a marked reduction in appetite, productive and reproductive potentials, which can result in severe economic losses in the dairy industry. Laboratory and wild animals also suffer from this ailment. Animal suffering and economic losses alike can be minimized through early diagnosis of the problem and by adopting suitable preventive and therapeutic measures. The book details the susceptibility of different animal species, important sources of toxicity, clinical signs and symptoms, pathophysiology, diagnostic methods, preventive and therapeutic approaches. It offers a valuable resource for scientists working in the fields of toxicology, veterinary science, animal nutrition, and environmental science, as well as for public health workers, animal welfare activists, public health veterinarians, field veterinarians, medical professionals and all others interested in the subject.
