Book Description
Most of the heavy metal are constituents of the aquatic environment some of them are biologically essential. But some metals like Hg, Cd, Zn etc. are highly hazardous to aquatic biota and normally occur in low concentration. A few investigators studied the toxic effects of mercury and other heavy metals to aquatic animals, particularly fishes to assess the pollution hazards due to metals. Amongst pollutants, non-essential metals are major cause of concern for aquatic environment because of their toxicity, persistency, tendency to accumulate in organism and in undergoing food chain amplification (Kneip and Louer, 1973 and Vinikour et al., 1980). Heavy metals such as Hg, Cu, Cd, Zn, Ni etc. generally exist within the earth crust in trace concentrations. In traces these metals are necessary for normal metabolism of the living organisms as these facilitate physiological functioning and also form part of structural components. However, anthropogenic activities such as industrial processing and use of metals, alloys and metallic compounds result in environmental contamination (Dar, 2002). Discharge of such metal containing effluents into the aquatic environment and drainage of residues of mining, there is manifold increase in the contents of these metals in the aquatic media (Kelkar, 2001) such as ponds, lakes, rivers and dams of India. According to a survey report of ATSDR (2001) almost 70% of the Indian available water has been reported to be extensively contaminated by heavy metals and other categories of chemicals. Heavy metal pollution in freshwater bodies assumes considerable significance because these are stable compounds and hence, not readily disposed off by the processes of oxidation, precipitation etc and adversely affect the activity of the animals. Heavy metals have a unique property of accumulation in organisms from very low concentration in water from lakes, rivers and dams (Kulkarni, 2000).

Book Description
Water as extraordinary substance, exists in three states as gases, liquid proved important for survivability of life (Simpiet al., 2011). Water quality has direct relation with aquatic productivity (Shrestha and Kazama, 2003). Riverine system comprises both main course and tributaries, carrying the one-way flow of sediment with load of dissolved matter and particulate phases coming from natural and anthropogenic sources (Rani et al. 2011). River also serves for domestic, industrial and agricultural disposal, transportation, getting food resources and for recreational activities (Dhote and Dixit, 2011). Dam and reservoir construction in river courses are booming all over the world for hydropower generation, flood control, irrigation, and water supply.Pollution of a river first affects its chemical quality and then systematically destroys the community disrupting the delicate food web. Diverse uses of the rivers are seriously impaired due to pollution and even the polluters like industry suffer due to increased pollution of the rivers. River pollution has several dimensions and effective monitoring and control of river pollution requires the expertise from various disciplines. Pollution of river is a global problem. In India it is reported that about 70% of the available water is polluted. The chief source of pollution is identified as sewage constituting 84 to 92 percent of the waste water. Industrial waste water comprised 8 to 16 percent. The indiscriminate and large-scale deforestation and over grazing in the watershed areas of river basins have caused soil erosion resulting in considerable silting of dams and shrinkage of river flows. This leads to the flooding of the rivers at the time of excessive rains. The disposal of waste leads to contamination of river and lakes chronically affecting the flora and fauna. According to surveys carried out on selected stretches of important rivers, it has been found that most of the rivers are grossly polluted. The domestic sewage discharged from a population of about 2 million gives rise to numerous water-borne diseases like typhoid, cholera, dysentery, poliomyelitis and cysticercosis, thereby affecting the human health and deterioration of the water quality.

Book Description
The COVID-19 pandemic has laid bare the vulnerabilities of socio-economic systems globally and exposed the risks that natural capital degradation imposes on human health, economy, and society. This book studies the environmental challenges faced by developing economies in a post-COVID-19 world. Exploring diverse case studies from South Asia and Sub-Saharan Africa, the volume discusses the impact that economic development and, recently, COVID-19 has had on the environment, ecology, and economy of these regions. It analyses nature conservation policies aimed at minimizing ecological damage arising from economic development and discusses the policy objectives of sustainable development. It also highlights the significant role that environmental economics networks have played in capacity building, framing of policies using ecological economics tools, and developing a local leadership trained in addressing local sustainability issues. An important contribution to the study of environmental economics of the Global South, the book will be of interest to students and researchers of economics, environment, development studies, development economics, environmental policies, and South Asia studies. It will also be useful for policymakers and NGOs working in this field.
