Quality Assurance in Environmental Monitoring Instrumental Methods, Sampling and Sample Pretreatment - Quality Assurance in Env

This set features two titles: "Quality Assurance in Environmental Monitoring: Sampling and Sample Pretreatment", edited by P. Quevauviller, and "Quality Assurance in Environmental Monitoring: Instrumental Methods", edited by G. Subramanian.;Based on the experiences of specialists, the title edited by Quevauviller describes the precautions that must be taken in environmental analysis, from the sampling to the sample pretreatment via the storage stage, in order to assure good quality. Typical pitfalls - and recommendations for avoiding them - are discussed. Emphasis is given to the monitoring of trace contaminants in environmental matrices (such as water, sediment, plants and air). The book is intended for environmental chemists.;The second title, edited by Subramanian, examines new developments in the legislation and monitoring of environmental pollutants. It explains modern instrumental methods such as GC/MS, thermal desorption and purge-trap methods, which are available to meet these legal requirements. It pays particular attention to methods of monitoring different types of chemicals, ranging from pesticides to industrial pollutants.
