The contamination of environment and water resources by Selenium
(Se) and its oxyanions from various sources are emerging
contaminants of significant health and environmental concern. The
primary sources include agricultural drainage water, mine drainage,
residues from fossil fuels, thermoelectric power plants, oil
refineries, and metal ores. Various methods and technologies have
been developed which focus on the treatment of selenium-containing
waters and wastewater. High concentrations of selenium in water
cause various adverse impact to human health, such as carcinogenic,
genotoxic, and cytotoxic effects. But in the lower concentrations,
it is a useful constituent of the biological system. The range
between toxicity and deficiency of selenium is minimal (40 to 400 g
per day), due to its dual nature. Selenium Contamination in Water
contains the latest status and information on selenium's origin,
its chemistry and its toxicity to humans. The book represents a
comprehensive and advanced reference book for students,
researchers, practitioners, and policymakers in working in the
field of metalloids, in particular selenium. A special emphasis is
given on its geological distribution, monitoring techniques, and
remedial technologies. As such, the authors critically analyze the
various techniques used for the monitoring and removal of selenium
from water. Featuring chapters arranged according to the major
themes of the latest research, with specific case-studies from
industrial experiences of selenium detection and removal, Selenium
Contamination in Water will be particularly valued by researchers,
practitioners, and policymakers in working in the field of
metalloids including selenium.
Comprehensive resource summarizing current approaches to generating
hydrogen from water and reducing CO2 into various hydrocarbons
Green Energy Harvesting: Materials for Hydrogen Generation and
Carbon Dioxide Reduction provides an in-depth treatment of the
subject by exploring the fundamentals required for the selection of
the materials, their synthesis methods, and possible ways to modify
them for higher efficiency and enhanced stability. The prospects of
adopting these sustainable solutions at a commercial level are
summarized. Special emphasis is given to the figure-of-merits for
currently developed systems for hydrogen generation and CO2
reduction and to an assessment of available materials in terms of
efficacy and efficiency. Green Energy Harvesting also includes
information on: Renewable energy in general, including the role of
renewable hydrogen and hydrocarbon fuels, and possible renewable
energy sources A fundamental understanding hydrogen generation and
CO2 reduction Device development and deployment status for
commercial usage and applications of H2 and hydrocarbon fuels in
various sectors Electrocatalysts, 2D materials, and hybrid
materials for CO2 reduction and H2 generation Green Energy
Harvesting is a highly useful guide for both novice and experienced
researchers involved in renewable energy and carbon dioxide
utilization that explains the current state of the field and
discusses future perspectives.
