The nonrenewable nature of fossil fuels, the co-production of greenhouse gas, particulate, and heavy metal emissions during combustion, and the political instability incited by dependence on non-domestic energy sources demand a more sustainable approach to energy development.
Atmospheric optics, study of optical characteristics and phenomena associated with the interaction of visible sunlight with atmospheric gases, particulates, and water vapour.
The respiratory tract is subjected to a variety of environmental stresses, including oxidizing gases, particulates, and airborne microorganisms, that together, may injure structural and functional lung components and thereby jeopardize the primary lung function of gas exchange.
The airway epithelium, a continuous pseudostratified population of cells lining the dichotomously branching airways, provides the barrier function that defends against inhaled gases, particulates, pathogens and other xenobiotics [1] [3].
Lung epithelial cells, a target cell of inhaled oxidants, are subjected to a variety of environmental stresses, including oxidizing gases, particulates, and airborne microorganisms.
A variety of analytical methods are available for measuring toxic gases, particulates, and odor and vary significantly in terms of cost, precision, accuracy, portability, maintenance requirements, and the ability to conduct continuous measurements.
However, this review focuses on the instruments available for measuring gases, particulates, and odor, and on plume dispersion models applicable to the determination of contaminants in the vicinity of CAFOs.
Research shows that levels of pollutants such as hazardous gases, particulate matter and other chemical nasties are usually higher indoors than out, even in the most polluted cities.
Automotive natural gas engines are designed to dramatically reduce the emission of polluting gases, particulate matter, and harmful substances associated to combustion of Diesel or gasoline fuels.
