Pages : 259
Book Description
The rapidly growing human population has increased the dependence on fossil fuel based agrochemicals such as fertilizers and pesticides to produce the required agricultural and forestry products. This has exerted a great pressure on the non renewable fossil fuel resources, which cannot last indefinitely. Besides, indiscriminate use ofpesticides for pests (weeds, insects, nematodes, pathogens) control has resulted in serious ecological and environmental problems viz. , (A) Increasing incidence of resistance in pest organisms to important pesticides. (B) Shift in pests population, particulary in weeds and insects. In weeds, species that are more closely related to the crops they infest have developed. In insects, scenario is most grim, the predators have been killed and minor insect pests have become major pests and require very heavy doses ofhighly toxic insecticides for their control. (C) Greater environmental pollution and health hazards (a) particularly from contamination of surface and underground drinking water resources and (b) from their inhalation during handling and application. (D) Toxic residues of pesticides pollute the environment and may prove hazardous to even our future generations. (E) Some agricultural commodities may contain minute quantities ofpesticides residues, with long tenn adverse effects on human and livestock health. Therefore, serious ecological questions about the reliance on pesticides for pests control has been raised. The use of fertilizers, besides causing environmental problems has also impoverished the soil health and decreased the beneficial soil fauna. For example, in some major crop rotations viz.

Languages : en
Pages : 324
Book Description
Herbicides represent one of the most widely used groups of pesticides worldwide for control of weed species in agricultural and non-crop settings. Due to the extensive use of herbicides and their value in weed management, herbicide research remains crucial for ensuring continued, effective use of herbicides while minimizing detrimental effects to ecosystems. Presently, a wide range of research continues to focus on improved herbicide use, environmental impact of herbicides, and even medicinal application of herbicide chemistries. In Herbicides - Advances in Research, authors cover multiple topics concerning current, valuable herbicide research.

Book Description
Current and projected worldwide shortages of energy, fertilizer, and irrigation water, coupled with a rapidly expanding population, are prompting agricultural scientists to seek, identify, and develop new crop species. Such crops should be energy- and water-efficient, well adapted to marginal lands, suited to intensive culture, and productive of ma
Biomarkers in Toxicology

ISBN: 0124046495
Category : Technology & Engineering
Languages : en
Pages : 1149
Book Description
Biomarkers in Toxicology is a timely and comprehensive reference dedicated to all aspects of biomarkers that relate to chemical exposure and their effects on biological systems. This book includes both vertebrate and non-vertebrate species models for toxicological testing and development of biomarkers. Divided into several key sections, this reference volume contains chapters devoted to topics in molecular-cellular toxicology, as well as a look at the latest cutting-edge technologies used to detect biomarkers of exposure and effects. Each chapter also contains several references to the current literature and important resources for further reading. Given this comprehensive treatment, Biomarkers in Toxicology is an essential reference for all those interested in biomarkers across several scientific and biomedical fields. - Written by international experts who have evaluated the expansive literature to provide you with one resource covering all aspects of toxicology biomarkers - Identifies and discusses the most sensitive, accurate, unique and validated biomarkers used as indicators of exposure and effect of chemicals of different classes - Covers special topics and applications of biomarkers, including chapters on molecular toxicology biomarkers, biomarker analysis for nanotoxicology, development of biomarkers for drug efficacy evaluation and much more
