This highly accessible book identifies the major air pollutants which cause human health concerns and examines the sources of these pollutants.With a focus on NOx gases, particulate matter (PM), tropospheric ozone, and volatile organic compounds (VOCs), Part 1 covers the theory and relates these pollutants to specific health outcomes by examining the nature of anatomical/physiological systems which are affected and the mechanisms by which these effects take place. Part 2 explores the legal and policy frameworks that govern local air quality management in the UK.It examines the responsibilities and powers of regulators, the role of national and international legislation, and how law and guidance are used to protect public health and improve environmental outcomes.Part 3 outlines the role of environmental health practitioners (EHPs) in dealing with local air quality management for communities before the applications used to control pollution are discussed, both in terms of using the law effectively and technological interventions which can trap air pollution at source. The book is principally aimed at undergraduate and/or post graduate students in Environmental Health and Public Health and EHPs practising in the field of air quality control.It will also be relevant to students of environmental sciences, health sciences, medicine and environmental law and policy.
