Air pollution

hansjosef29

Air pollution is the introduction of chemicals or other materials into the atmosphere that can harm humans or the environment. It occurs naturally, such as from volcanoes, or is man-made through processes like fuel combustion from vehicles, factories, and power plants. Air pollutants can be classified as primary emissions or secondary pollutants formed when primary ones react in the air. Air pollution is a major global health risk and causes many respiratory and heart conditions, as well as lung cancer and early death. Efforts to reduce pollution include using cleaner fuels in vehicles and industry and installing pollution control devices.

Quantification of rate of air pollution by means of

IJARBEST JOURNAL

To develop efficient strategies for pollution control, it is essential to assess both the costs of control and the benefits that may result. These benefits will often include improvements in public health, including reductions in both morbidity and premature mortality. Until recently, there has been little guidance about how to calculate the benefits of air pollution controls and how to use those estimates to assign priorities to different air pollution control strategies. In this work, a method is described for quantifying the benefits of reduced ambient concentrations of pollutants (such as ozone and particulate matter) typically found in urban areas worldwide. The method applies the data on Jakara, Indonesia, an area characterized by little wind, high population density (8 million people), congested roads, and ambient air pollution. The magnitude of the benefits of pollution control depends on the level of air pollution, the expected effects on health of the pollutants (dose-response), the size of the population affected, and the economic value of these effects. In the case of Jakarta, the methodology suggests that reducing exposure to lead and nitrogen dioxide should also be a high priority. An important consequence of ambient lead pollution is a reduction in learning abilities for children, measured as I.Q. loss. Apart from that, reducing the proportion of respirable particles can reduce the amount of illness and premature mortality.

Towards an accurate Ground-Level Ozone Prediction

IJECEIAES

This paper motivation is to find the most accurate technique to predict the ground level ozone at Al Jahra station, Kuwait. The data on the meteorological variables (air temperature, relative humidity, solar radiation, direction and speed of wind) and concentration of seven pollutants of environment (SO2, NO2, NO, CO2, CO, NMHC, and CH4) were applied to forecast the ozone concentration in atmosphere. In this report, three methods (PLS regression, support vector machine (SVM), and multiple least-square regression) were used to predict ground-level ozone. We used Fifteen parameters to evaluate the performance of methods. Multiple least-square regression, partial least square regression (PLS regression), and SVM using linear and radial kernels were the best performers with MAE (mean absolute error) of 9.17x 10-03, 9.72 x 10-03, 9.64 x 10-03, and 9.12 x 10-03, respectively. SVM with polynomial kernel had MAE of 5.46 x 10-02. These results show that these methods could be used to predict ground-level ozone concentrations at Al Jahra station in Kuwait.

Particulate matter, air quality and climate

Yahsé Challa

This document reviews recent developments in particulate matter (PM) or atmospheric aerosol science and its connections to environmental policy issues. It summarizes that while PM has significant impacts on human health and climate, uncertainties remain regarding the relative importance of different PM components and sources. Reducing emissions of black carbon and ammonia could help mitigate some PM impacts cost-effectively. However, a prioritized plan to address the full range of PM effects is still needed due to gaps in understanding processes like global climate impacts and the response of PM precursors to future changes. The review advocates an integrated approach to air quality and climate policy given the evidence of PM's importance to both issues.
