This article will be helpful for engineers in the future to construct exhaust systems to attenuate noise pollution.
There is a need to develop new and renewable energy sources, including wind, solar, water, and nuclear power; reduce coal consumption; and attenuate air pollution from the thermo-power generation process.
Windy weather in these Danish cities tends to attenuate traffic pollution although PM10 levels in Copenhagen are compatible with concentrations in London and Paris, but about half those in southern Europe such as Malan and Barcelona.
Designing soil filtration systems or vegetated filter strips as a means of attenuating water pollution should take into account soil purging capacity.
Solar radiation can be significantly attenuated firstly by pollution in the boundary layer of the atmosphere and secondly by the dirt deposited on the surfaces of buildings, for example on exterior surfaces, resulting in lower reflectance and glazing, and in lower transmittance.
Atmospheric pollution attenuates solar radiation.
Thus, it is plausible that statin use could attenuate proinflammatory effects of air pollution, and reduced effects of air pollution on inflammation and heart-rate variability among statin users compared with nonusers have been reported (Schwartz et al. 2005; Zeka et al. 2006).
The economic viability of zig-zag transformer makes it an attractive proposition in case of small autonomous units because in addition to providing neutral compensation it additionally attenuates the third harmonic pollution of the supply current.
Using the average first trimester air pollution exposure attenuates any misclassification caused by, for example, travelling more than with a shorter time window.
In time-series studies, inclusion of scheduled admissions could attenuate observed associations with air pollution, due to inclusion of admissions for which timing of the event was not caused by air pollution.
