Nanotechnology is a much talked about, and rapidly expanding area of science, which is sometimes little understood. It looks set to make a significant impact on human life and, with numerous commercial developments emerging, will become a major industry over the coming years. Nanotechnology can be broadly described as developing or exploiting products at nanometre dimensions (i.e. as having one dimension less than 100 nanometres). Such materials have a larger surface area to volume ratio than conventional materials which provides them with an increased level of reactivity, and consequently, toxicity per unit mass. This book sets the subject into context by first of all describing the current range of products containing nano-materials and then looking at the consequences for the environment and human health relating to the introduction of nanoparticles and nano-tubes. Nanotechnology: Consequences for Human Health and the Environment discusses some of the more controversial issues associated with the field including: nanoparticles in the environment, occupational exposure, toxicological properties, human health issues and safety. This authoritative and comprehensive book will be of interest to both scientists and technologists but also to regulators and government. This title is also available in hardback.

The impact of air pollution on human health is currently of international concern. A comprehensive review of the subject is given in this volume, which complements the previous title covering air quality management. Dealing with the common gaseous and particulate air pollutants, including chemical carcinogens, it reviews the epidemiological and exposure chamber study research as well as considering mechanistic studies in the case of particulate matter. Air Pollution and Health also addresses the practical issue of setting standards for human exposure to air pollution by including the philosophy of standard setting and a review of currently available standards, along with a description of the setting of USEPA revised standards for ozone and particulate matter. Current knowledge of indoor air pollution is also discussed. As with all other books in the series, this volume will be of interest to the general public as well as being an important reference source for all those involved in the field, be it as student, industrialist, government agent, or health professional.

Enormous increases in agricultural productivity can properly be associated with the use of chemicals. This statement applies equally to crop production through the use of fertilizers, herbicides and pesticides, as to livestock production and the associated use of drugs, steroids and other growth accelerators. There is, however a dark side to this picture and it is important to balance the benefits which flow from the use of agricultural chemicals against their environmental impacts which sometimes are seriously disadvantageous. Agricultural Chemicals and the Environment explores a variety of issues which currently are subject to wide-ranging debate and are of concern not only to the scientific establishment and to students, but also to farmers, landowners, managers, legislators, and to the general public.
