The field of techniques for preparing, preconcentrating, quantitating, tracking, and remediating trace pollutants is vast. This volume is intended to be a diverse 'sampling' of such methods, each chapter representing one specific field of environmental chemistry analyses. The book is divided into three sections: air, soil and minerals, and water. The air section includes studies on airborne particulate matter and other pollutants present in trace levels. The soil and mineral section includes chapters on X-ray fluorescence spectroscopy, mercury-thiourea complex ion chromatography, and mercury speciation analyses. The water section of the book focuses on specific contaminants in water and addresses the existing and future remediation methods for metals in water.
