Mathematical modeling of emission and control of greenhouse gases
(Department of Mathematics, 2018-06-30) Mishra, A.K.
The enhanced concentration of carbon dioxide (CO2) in the Earth’s atmosphere
is significantly responsible for the menace of global warming and the associated
climate changes [29]. The increment in the concentration of atmospheric CO2 is
attributed to human activities such as fossil fuel burning and land use changes
[29]. Deforestation accounts for nearly 90% of CO2 emissions from land use
changes [28]. Forests are one of the major sinks of CO2 on the Earth. Trees
during the photosynthesis process absorb CO2 from the atmosphere and stock
it in the form of biomass. Every year forests absorb gigatons of carbon in this
process. Clearing of forests causes increase in concentration of CO2 in two ways;
firstly, it reduces the global uptake of CO2 through photosynthesis process and
secondly, the carbon stored in the trees is released back to the atmosphere in the
form of CO2 when the wood is burned or left to decompose after deforestation.
In the last few decades, global forest biomass has declined at an alarming rate.
Between 1990 to 2005, the total forest area has declined at annual rate of 0.21%
and the carbon stock per hectare in forest biomass has declined at the rate
0.02% [15]. This severe destruction of forest has contributed significantly to the
inexorable rise of atmospheric concentration of CO2.
A low cost approach to remediation of Cadmium contaminated soils using organic and inorganic amendments
(Department of Soil Science and Agriculture Chemistry, 2015-06-30) Ghosh, Amlan Kumar
Over the past few decades, the term heavy metals (such as lead, mercury, and cadmium) have been associated with contamination and potential toxicity or eco-toxicity, even at low concentration tend to bio-accumulate and cannot be processed by living organisms (Rand et al., 1995). Often as pollutants, which poses severe threats to environment and their occurrence in soils indicates the presence of natural or anthropogenic sources (Yoon et al., 2007).
Evaluation of efficacy of phytoremediation in decontamination effluents using biossay analysis of fish tissue bearing
(Department of Zoology, 2013-03-22) Banerjee, T.K
Toxicity of the effluent generated at the Rajrappa coalmine complex under central coalfields limited, Jharkhand was analyzed. Coal mining generated huge quantity of toxic effluent which regularly pollutes the neighboring wetlands where the local inhabitants often cultivate fishes for eating purposes
Toxicity of dying chemicals used in carpet industry on the skin and gills of certain freshwater teleosts
(Department of Zoology, 2014-12-31) Mittal, Swati
Increasing industrialization and urbanization leads environmental pollution. A polluted ecosystem may threaten fish population, can cause accumulation of pollutants and environmental toxins in fish, and thus could have direct effect on human nutrition and health.
