Discuss the following:
(a) Toxins and Environmental health.
(b) Cost of waste generation and disposal.
(c) Insufficient public Awareness and its reasons.
(d) Ganga Action Plan.
(a) Toxic environmental hazards can be viewed through several different constructs; developed versus developing world, occupational versus background exposure, traditional versus new threats, natural versus non-natural compounds, visible versus hidden pollutants, toxicity of compounds versus health outcomes. On a global scale, the traditional environmental hazards such as biologically contaminated water, poor sanitation, indoor smoke from biomass burning, and rampant disease vectors (for example, malaria) remain the primary source of ill health in children Solving these problems is predominately dependent on political will, rather than on further evaluation of published data. By contrast, significant scientific uncertainty remains about the long term consequences of “modern” toxic threats to health from air, water, and soil pollution produced by unsustainable level of production and consumption. This form of environmental contamination may either be from natural compounds that are concentrated by industrial processes, or from exclusively non-natural substances. Non-natural toxic threats alone represent a major potential problem.
(b) Technology options including resource recovery are reviewed with special emphasis on constraints arising particularly in developing countries. Cost control and recovery is complex, and it has rarely if ever been demonstrated that a potential exists for making a solid waste management project profitable in its entirity. Solid waste management represents a net cost which may be minimized by better operations and appropriate recycling. Financial and economic backgrounds including tax structures have an overriding influence on apparent costs, and sound financial management is essential. Hazards of relying on the commercial sector alone to manage waste collection and disposal are emphasized as well as the long term problems with highly sophisticated equipment in countries that lack Foreign exchange and local skills for their maintenance and repair.
(c) Public awareness can play a vital role in environmental management.
