Dr. Shekhar Mallick, Sci 'B'
Group Works on
Plant - mediated emissions of greenhouse gases.
Monitoring and assessment of water and air and soil quality.
Plant's role in scavenging urban and industrial pollution.
Toxicity and tolerance responses of plants to heavy metal
pollution.
Eco-restoration of degraded wastelands.
Environmental Impact Assessment (EIA) and Eco-auditing.
Green-belt development.
Objectives
Assessment of Global Warming Potential (GWP) by trace gases.
Development of abatement strategies to contain urban and
industrial pollution.
Bioremediation of contaminated sites and industrial
wastes, Molecular Bioremediation
Eco-restoration of degraded ecosystems.
Eco-planning and management of industries.
Removal of organic pollutants through sorption.
Salient Achievements
National
Study of seasonal dynamics of methane efflux from wetlands
and computation of annual methane budget. This may be used
in the preparation of yearly methane budget for wetlands in
India.
Investigation on agricultural emission of GHGs, particularly
methane and nitrous oxide to compute their annual budgets.
Mitigating options to attenuate methane and nitrous oxide
emissions from agricultral fields.
Identification of 60 pollution tolerant plant species (trees
/ shrubs) with high scavenging potential to be grown along
road side as avenue trees and in green-belts around industries
for mitigation of air pollution.
Identification of metal hyper accumulator aquatic plants
to be used in the phytoremediation strategies to remove heavy
metals from contaminated wetlands. Phytochelatin synthesis
in metal accumulator plants. Phytochelatin synthesis gene
characterized from aquatic plant.
Development of protocols to vegetate the degraded lands
and the industrial wastes like fly ash.
Development of expertise on EIA and eco-auditing studies
for better industrial planning and management.
International
Probing the mechanism of methane and nitrous oxide transport
through aquatic and terrestrial plants from rhizosphere to troposphere.
Tracing the mechanism of metal uptake, tolerance and detoxification
by aquatic and terrestrial plants.
Local methane and nitrous oxide budgets may be used for
the preparation of national and international yearly methane
and nitrous oxide budget.
Feed Back Required
`
National Level
Suggestions / views / comments are
needed from time to time from the experts in India to improve
our know how on phytoremediation, global warming, eco-restoration
and eco-planning and management. Software's developed by other
agencies may be required for the prediction models for pollutant
dispersion, which may help in designing the green-belts around
industrial establishments.
International Level
Exposure to latest developments in
the respective fields through journals / seminar / symposia and
working abroad for a certain period.
