Since the synthesis of DDT during 1874 several insecticide molecules have been
identified and synthesized globally for the control of insect pests, pathogens, microbes,
vectors of human and animal diseases, weeds and other obnoxious organisms.
Currently, 1.8 billion kgs of pesticides are used annually worldwide in the form of
herbicides, insecticides and fungicides. There are more than 1055 active ingredients
registered as pesticides till date implying that there is no best alternate for the
Metabolism of pesticides denotes that any foreign substance that enters in the living
system and how it will be changed into non-toxic and thrown out due to the
enzymatic activity and other mode of action. When chemical toxins applied to nonliving
substance (soil and water) that will lose the toxic principles by degradation
process due to the action of biotic and abiotic factors. The time to nullify the toxicity is
of prime importance and it vary depending upon the chemical molecule and
Many pesticides are being highly stable and continue to kill the target and the
host long after the application which is both advantageous and disadvantageous.
Thus, the detection and assays of pesticide residues have significant role to know level
of residual pesticide molecules. The present edition of volume attempted to
consolidate significant advancement of research at worldwide on pesticide residues.
The status of pesticide usage pattern and residue level in food from plant and animal
origin at different regions are described in-depth in the chapters....
I would like to express my
deepest gratitude to all theauthors who contributed to this book by sharing their
valuable works with us. This book should prove useful to students, researchers, and
experts in the area of conservation biology, genetic diversity, and molecular biology.
The year 2010 was celebrated as the international year of biodiversity by the United
Nations and it has been a unique opportunity to realize the vital role that biodiversity
plays in sustaining the life on Earth.
