About the Book
"Agrochemicals are the result of modern technology that depends on inorganic fertilizers and pesticides. Over use of these chemicals have severe effects on environment that may lead to an immediate and long term effects. This work focuses on both national and international studies regarding the effects of pesticide and chemical fertilizer residues on nature, as well as impacts on human health. The enormous amount of chemical contaminants that are currently found in air, soil, water and sediments of our planet, mostly as a result of human activities, call for an evaluation of their risks to the web of life. The contaminants that potentially result in adverse biological effects – whether at individual, population, community or ecosystem level – the so-called pollutants, are of concern. For obvious reasons, pollutants that relate to our food resources are of particular interest and require priority in risk assessment. Among the latter chemicals are those used in agricultural production, also called agrochemicals, which include pesticides of various kinds, plant growth regulators, repellents, attractants and fertilisers. These chemicals are intentionally added to the environment for controlling pests and diseases of crops, requiring an accurate assessment of the maximum amounts that can be applied. Because of their huge market in all continents, agrochemicals are among the most common pollutants in one fifth of the Earth’s land. Also, given the high toxicity of most insecticides, herbicides and fungicides to their target and nontarget organisms, their negative impacts on the environment cannot and must not be unnoticed. Definitely, pesticides constitute one of the main drivers of population decline in some wildlife species. Therefore, proper evaluations of the risk that pesticides and other agrochemicals pose to organisms and ecosystems should be conducted in a scientific manner.
Two-Volume ‘Brig’s Handbook of Methods & Research in Toxicity and Hazard of Agrochemicals’ is intended to provide an overview of toxicology that examines the hazardous effects of common agrochemicals employed every day in our agricultural practices. Furthermore, it provides insights into the difficulties and challenges of performing risk evaluations of agrochemicals.
Agricultural safety and the resulting environmental and health problems from pesticide application are increasingly attracting global attention. However, a large input of pesticides leads to excessive residues that adversely affect the quality of agricultural goods. Although the impacts of pesticides on agricultural products vary according to the type of pesticide used, all pesticide residues cause nutrient imbalance and reduction in the quality of agricultural products. Pesticide residues affect human health. In fact, pesticide application has become a great threat to human health. Studies have shown that long-term low-dose exposure to pesticides leads to the development of respiratory diseases such as asthma. Such exposure also leads to reduced sperm quality and sperm count, causing sterility. Pesticide poisoning is more significant in developing countries compared to developed countries.
Two-Volume ‘Brig’s Handbook of Methods & Research in Toxicity and Hazard of Agrochemicals’ will be of valuable to those directly engaged in the handling and use of agrochemicals and that this handbook will continue to meet the expectations and needs of all interested in the different aspects of human and environmental risk toxicities."
