Title : Unsafe chromium pollution and control for the environmental plant biology and biotechnological development
Abstract:
The environmental and social problems including human health issues caused by injudicious use of chromium in Tamil Nadu, India are investigated. The chrome (a heavy metal) has been used in tanning skin in chrome tanning leather industries. During the process of leather manufacturing by chrome tanning process, the hides/skins are treated with Basic Chromium Sulphate (BCS) powder. Chrome tanned leather can also be called as wet blue leather. Research investigations are conducted in Chrompet , Pallavaram , Chengalpattu, and Chennai areas for prediction and assessment of the environmental and social damages due to the small and large chromium -based tanneries that have impacted considerably to the natural environment or the bio-physical environment and the cultural and socioeconomic or the manmade environment. The purpose of tanneries is to manufacture usable leather from chromium-based tanneries. Chrome tanned leather production or tanning skin by two- bath process for leather production to grow into a major industry. Green chemistry can be defined as the design and development of chemical products and processes that reduce or eliminate the use or generation of hazardous substances and green chemistry applies across the life cycle of products and processes including design, manufacture, use and ultimate disposal. It is concluded that environmental health impact assessment ( EHIA ) process should be conducted for certain plant biology and biotechnological projects, plans, programs, legislative actions, policies in the project planning and decision-making process. Lack of organizational focus is observed that should mitigate adverse environmental health impacts on climate change and minimize the impact of air pollution, water pollution, soil and sanitation impact and land pollution eutrophication effect (or impact) as well as forest and wildlife conservation.
