PM2.5 in the period between November 22nd to December 22nd 2007 with the mean of 33g/m3 had the maximum amount and in the period between July 22nd to October 22nd 2007 it had the minimum amount with the mean of 8g/m3. Conclusion: Based on the findings of this study, the densities of...
EMD is based on the following assumptions: first, there are at least two extreme values, a maximum and a minimum; second, the local time domain characteristics for the data are uniquely determined by the time scale between the extreme points; and third, if there are no extreme point in the...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inc
resulted in tighter buildings with recirculated air for building ventilation and minimum amounts of fresh air being brought into commercial buildings. Ventilation for comfort began to compete with ventilation for health. This minimized the amount of air to be heated or cooled and hence conserved...
(including chronic respiratory disease and premature mortality) associated with short- and long-term exposure to particulate matter. The CAA, enacted in 1970 and amended in 1990, requires EPA to set minimum NAAQS standards for pollutants anticipated to endanger public health and welfare, and where ...
with a minimum value of 29.48, and a maximum value of 137.84. This reflects a decrease compared to the average AQI of 64.99 from 2014 to 2022, and reflects a slight increase compared to the 2014–2022 minimum value of 29.21 and a slight decrease compared to the 2014–2022 maximum value ...
Air quality modelling, wind profile study and application of plume dispersion modelling techniques help in identifying regions which are the most suitable for industrial setup and have minimum impact on the health of residents. Stringent monitoring on the use of vehicle-based emission control devices,...
a minimum number of monitors are required for areas with certain populations considering the level of air pollution severity and for areas near major traffic corridors. To ensure data quality, change in a monitoring station has to be approved, monitoring methods are recommended, and collocated monito...
