Muller VI Contents Chapter 8 Pesticides: Environmental Impacts and Management Strategies 187 Harsimran Kaur Gill and Harsh Garg Preface Today, exposure to pesticides is one of the major concerns related to the safety of the envi‐ ronment worldwide. It is estimated that approximately 1.8 billion people engage in agricul‐ tural practices, and most use pesticides to protect the food and commercial products that they produce. Most people employ pesticides occupationally for public health programs and in commercial applications, while many others use pesticides in lawn and garden applica‐ tions and for domestic protection. Although there have been attempts to decrease pesticide use through organic agricultural practices and the use of other alternative technologies to control pests, additional efforts must be made to find alternatives to chemical pesticides. At present, continued exposure to pesticides from a number of different sources, including, among others, occupational exposure, home and garden use, spray drifts, residues in house‐ hold dust, food, soil, and drinking water, remains a serious health problem in both develop‐ ing and developed countries. Risk assessment plays a crucial role in the process of decision making about the use of pesticides, both new and existing. Accumulating experience sug‐ gests that postmarket epidemiological surveillance of pesticide safety represents an essential method to ensure public health and the quality of our environment. Epidemiological studies have suggested that pesticides on the market currently may cause deleterious effects, e.g., neoplasias and other diseases in non-target species, including humans. Furthermore, many occupational and agricultural workers experience unintentional pesticide poisoning each year worldwide. In addition to causing environmental damage, wild non-target species are frequently affected by pesticide exposure because they possess physiological or biochemical similarity to the target organisms. This book, “Pesticides - Toxic Aspects,” is intended to provide an overview of toxicology that examines the hazardous effects of common chemical pesticide agents employed every day in our agricultural practices. We aimed to compress information from a diversity of sources into a single volume. The chapters include a large variety of pesticide-related topics about the effects of several methods of control on undesired weeds and pests that grow and reproduce aggressively in crops, as well as their management and several empirical method‐ ologies for study. The topics considered include details of the effects of pesticides on target and non-target organisms; the behavioral consequences of exposure to toxic chemicals, with a focus on the nervous system; the study of the action mechanisms of pesticide toxicity in individuals exposed, with emphasis on the interaction of pesticides with the DNA molecule; the lethal and sublethal effects of the herbicide glyphosate in freshwater organisms; a dis‐ cussion of pesticides as economic poisons and the balance between the economic effects of pesticide use and their adverse effects on the environment and non-target organisms; a de‐ scription of field observations and laboratory measurements of pesticide concentrations in wild species; a comparative analysis of two overwhelmingly different agricultural settings VIII Preface after pesticide exposure; and, finally, a detailed study of alternative types of pesticide use in non-agricultural areas. Many researchers have contributed to the publication of this book. The combination of ex‐ perimental and theoretical pesticide investigations of current interest will make this book of significance to researchers, scientists, engineers, and graduate students who make use of those different investigations to understand the toxic aspects of pesticides. The chief objec‐ tive of this book is hence to deliver state-of-the-art information for comprehending the toxic‐ ity of several pesticides in target and non-target organisms. We hope that this book will continue to meet the expectations and needs of all interested in the different aspects of pesti‐ cide toxicity. Marcelo L.

Introduction Global pesticide use is increasing, and such growth is recognized as stemming from agricul‐ tural needs in response to global food stress. However, pesticides are used on other areas than agricultural fields. Even if agricultural consumption of pesticides is undoubtedly the main use, the transfer from other, more impervious surfaces is regarded as a key point in understanding the fate and the global impact of pesticides, named biocides, when used for nonagricultural purposes. In the overall environment these chemicals are combined with those applied to agricultural areas, leading to confusion and thus a probable underestimation of nonagricul‐ tural pesticides. Numerous information campaigns have targeted agricultural users. The high remaining level of background contamination of rivers highlights that minoring even obliter‐ ating urban consumers precisely stultify the considered information campaigns. The ambig‐ uous situation of port contamination will also be discussed in the present chapter. However, nonagricultural uses mainly involve the same chemicals (e.g., herbicides) as agricultural uses. In the present chapter, the main biocides used will be listed, and then the differences in consumption depending on countries and legislation. The environmental traces of the main pesticides will be summarized with the confounding uses for watershed scale interpretation. The consequences of pesticide use depend on transfer rates, themselves conditioned by the type of surface where these chemicals are applied and their imperviousness. For highly artificialized urban areas, where biocides are mainly used, such information is pivotal: they explain a minor but significant part of aquatic environment contamination. Alternatives
