Description of  Bioremediation and Biotechnology, Vol 3: Persistent and Recalcitrant Toxic Substances

Healthy environment is essential for any biota, without which survival is not possible. The qualities of environment are continuously being degraded by persistent and recalcitrant pollutants, released into the different ecosystems due to anthropogenic activities viz., improper wastewater discharge, unscientific solid waste management, rapid industrialization, urbanization, and application of recalcitrant substances and pesticides. These persistent pollutants not only affect the living organisms in soil and water, but have deleterious impacts on human health. Undoubtedly, synthetic substances like pesticides, herbicides, etc., are helpful for controlling the unwanted pests and plants, hence are essential for increasing the agricultural yield. But, the presence of these substances also has long term implications as these chemicals have long residential period in any ecosystem. Pesticide application on crops directly affects non target organisms, soil health and also reaches nearby freshwater bodies. There are numerous technologies available for monitoring, assessing and remediation of these recalcitrant pollutants, but are expensive as well as inefficient for sustainable future. Bioremediation and biotechnology, nowadays play a key role in degradation of persistent pollutants. Furthermore, these sustainable techniques can remove pesticides from environment in versatile, cost effective and ecofriendly manner. The current volume is an expertly curated account on pollution remediation with a special focus on persistent and recalcitrant contaminants across diverse habitats.
