However, because many time-varying risk factors for asthma are intermediates on the causal pathway (e.g., aeroallergens, air pollution, activity patterns), associations estimated in this study represent the total effect of temperature on asthma risk.
Leontief (1970) and Leontief and Ford (1972) enlarged the traditional input output model to account for the generation of pollutants by the economic system and the operation of anti-pollution activities.
As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building façades (plastering and finishing) by limiting attack from microorganisms and pollutants, its photocatalytic anti-pollution activity under solar and visible (no UV) light for nitrous oxide (NOx) and volatile organic compound (VOC) removal was studied.
De-pollution activity of cement paste samples, added with 0.0%, 0.5%, 1.0%, 3.0% and 5.0% (based on the dry weight of the cement used) of titanium dioxide nanoparticles, TiO2, was evaluated through the degradation of nitrogen oxides, NOx, pollutants.
Public health impact of outdoor air pollution control activities should be assessed to monitor and modify such mitigation activities.
For actual discharges, environmental laws generally prescribe specific thresholds of allowable pollution; for activities that create a risk of discharge, environmental laws generally establish management practices to reduce that risk.
All of the industries undertook some pollution prevention activities, though each of them had potential for improvement.
The information provided here is helpful in estimating the magnitude of non-stormwater flow entries into storm drains and designing the necessary pollution control activities, as well as combating city floods in storm events.
We examined the feasibility of conducting a local assessment of the public health impacts of cumulative air pollution reduction activities from federal, state, local, and voluntary actions in the City of New Haven, Connecticut (USA).
