Dust and Health: Challenges and Solutions

Description:

This book discusses the sources, human health hazards and risk prevention strategies associated with aeolian dust particles (fine and ultrafine) in the atmosphere. It covers the challenges of accurately forecasting aeolian dust and the need to raise public awareness on the warning signs and harmful impacts of airborne dust. Also discussed is the presence of microorganisms, heavy metals and other pollutants in dust which contributes to harmful impacts on human health as well as management and treatment options for the various health issues that can result from exposure. The book is a useful resource for scientists, engineers and policymakers interested in dust and health.
