Environmental health is a branch of public health, which studies all aspects of the natural and built environment that affect human health. Five significant disciplines are integral to the field of environmental health. These include toxicology, environmental epidemiology, environmental engineering, exposure science and environmental law. Toxicology, epidemiology and exposure science studies are integrated to conduct a risk assessment of chemicals, specific chemical mixtures and health risk factors. These studies are then used for regulating chemical emissions, developing and implementing environmental health policies such as imposing standards for proper sanitation, etc. Some of the areas of focus in environmental health include indoor and outdoor air quality, climate change, noise pollution control, liquid waste disposal, solid waste management, toxic chemical exposure, vector control, medical waste disposal and management, land use planning, etc. This book elucidates the concepts and innovative models around prospective developments with respect to environmental health. It presents researches and studies performed by experts across the globe in relation to the protection and sustainability of the environment. It attempts to assist those with a goal of delving into this field.
