Pesticides in the Modern World


Book Description

The book offers a professional look on the recent achievements and emerging trends in pesticides analysis, including pesticides identification and characterization. The 20 chapters are organized in three sections. The first book section addresses issues associated with pesticides classification, pesticides properties and environmental risks, and pesticides safe management, and provides a general overview on the advanced chromatographic and sensors- and biosensors-based methods for pesticides determination. The second book section is specially devoted to the chromatographic pesticides quantification, including sample preparation. The basic principles of the modern extraction techniques, such as: accelerated solvent extraction, supercritical fluid extraction, microwave assisted extraction, solid phase extraction, solid phase microextraction, matrix solid phase dispersion extraction, cloud point extraction, and QuEChERS are comprehensively described and critically evaluated. The third book section describes some alternative analytical approaches to the conventional methods of pesticides determination. These include voltammetric techniques making use of electrochemical sensors and biosensors, and solid-phase spectrometry combined with flow-injection analysis applying flow-based optosensors.




Biosensors in Environmental Monitoring


Book Description

During recent years both research activity and the number of reports on biosensor systems applied to environmental analysis have increased significantly. Compounds present in the environment have increasingly been shown to have effects on biological systems such as cells, enzymes, binding proteins, and DNA. In order to deal with the increasing demand for information about possible pollution of the environment there is need for improvements to analytical methods. Thus, biochemistry-based analytical methods should offer the possibility of monitoring these effects. This text provides an overview of existing biosensor principles, commercially available instruments, and related biochemical assays which have been developed and applied to environmental monitoring. Providing the reader with detailed information on methodology and a description of the practical application of selected sensors, this text also includes reports on established chemical methods for comparison. This volume presents fundamental principles together with examples of applications and discussion of drawbacks, and future developments. Of interest to all in the field of environmental analysis and biosensor technology, this text provides a comprehensive treatise on the latest research and developments in the field.
