Clay is an abundant naturally occurring raw material with different unique characteristics such as high surface area, chemical and mechanical stability, cation exchange ability, and more. This book is a comprehensive overview of clay science, covering the characterization and application of clay minerals. Applications such as stratigraphic correlation, environmental deposition indication, pharmaceutical uses, wastewater treatment, construction, and agriculture are explored. This book will provide an important reference for researchers, scientists and engineers who have a keen interest in clay...

A growing body of evidence suggests that air pollution from vehicles is an inescapable part of industrialised world. Though vast majority of research have focussed on effect of air pollutants on health of individuals, but studies regarding occupational exposure to petrochemical fumes are relatively few and those available, have yielded inconsistent results.So, in our research, we laid emphasis on changes in lung functions in petrol-pump workers chronically exposed to petrol/diesel fumes. Surprisingly, most workers remain asymptomatic till significant lung damage occurs.Even if observed values...
