Ambient Air Quality

Though water and land pollution is very dangerous, air pollution has its own peculiarities, due to its transboundary dispersion of pollutants over the entire world. In any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. Air pollution is one of the serious problems faced by the people globally, especially in urban areas of developing countries like India. All these in turn lead to an increase in the air pollution levels and have adverse effects on the health of people and plants. Western countries have conducted several studies in this area, but there are only a few studies in developing countries like India. A study on ambient air quality in Tiruchirappalli urban area and its possible effects selected plants and human health has been undertaken, which may be helpful to bring out possible control measures.

Beijing-Tianjin-Hebei (BTH) and its surrounding areas are one of the most polluted regions in China. Xingtai, as a heavy industrial city of BTH and its surrounding areas, has been experiencing a severe PM2.5 pollution in recent years, characterized by extremely high concentrations of PM2.5. In 2014, PM2.5 mass concentrations monitored by online instruments in urban areas of Xingtai were 116, 77, 128, and 200 µg m−3 in spring, summer, autumn and winter, respectively, with annually average concentrations of 130 µg m−3 exhibiting 3.7 times higher than National Ambient Air Quality Standard (NAAQS) value for PM2.5 (35 µg m−3). To identify PM2.5 emission sources, ambient PM2.5 samples were collected during both cold and warm periods in 2014 in urban areas of Xingtai. Organic carbon (OC), sulfate, nitrate, ammonium and elemental carbon (EC) were the dominant components of PM2.5, accounting for 13%, 11%, 12%, 11% and 8% in the cold period, respectively, and 11%, 12%, 9%, 6%, and 5% in the warm period, respectively. Source apportionment results indicated that coal combustion (24.4%) was the largest PM2.5 emission source, followed by secondary sulfate (22.2%), secondary nitrate (18.4%), vehicle exhaust dust (12.4%), fugitive dust (9.7%), construction dust (5.5%), soil dust (3.4%) and metallurgy dust (1.6%). Based on PM2.5 source apportionment results, some emission control measures, such as replacing bulk coal with clean energy sources, controlling coal consumption by coal-fired boiler upgrades, halting operations of unlicensed small polluters, and controlling fugitive and VOCs emission, were proposed to be implemented in order to improve Xingtai’s ambient air quality.

The increased occurrence of smoggy days in major Pakistan cities is of major concern to the general public. This paper explores the major sources of pollutants total suspended particles and lead concentration, a key contributor to the smog in Faisalabad, one of the largest cities in Pakistan. Evidence indicates that the total suspended particles and lead concentration formed through NOx, SOx, NH3, VOCs, etc. have a strong impact on human health. As a result, air pollution control should not simply focus on controlling particulate emission, but should involve adopting an integrated multi pollutant control strategy. In addition to identifying the major sources of air pollution, this paper explores its impact on environmental and human health. The results also compare with the permissible limit of NEQS and USEPA standards. The study shows that TSP concentration 80% values within the permissible limits of ambient air quality according to the standards of USEPA and NEQS. In the samples, Lead concentration is higher than the USEPA and NEQS standards of ambient air quality 1.5μg/m3 and 2μg/m3 respectively. The research suggests that adequate government regulation, public awareness, regional collaboration and industrial compliance are keys to successfully controlling air pollution.

China started to implement comprehensive measures to mitigate traffic pollution at the end of 1990s, but the comprehensive effects, especially on ambient air quality and public health, have not yet been systematically evaluated. In this study, we analyze the effects of vehicle emission control measures on ambient air pollution and associated deaths attributable to long-term exposures of fine particulate matter (PM2.5) and O3based on an integrated research framework that combines scenario analysis, air quality modeling, and population health risk assessment. We find that the total impact of these control measures was substantial. Vehicular emissions during 1998–2015 would have been 2–3 times as large as they actually were, had those measures not been implemented. The national population-weighted annual average concentrations of PM2.5and O3in 2015 would have been higher by 11.7 μg/m3and 8.3 parts per billion, respectively, and the number of deaths attributable to 2015 air pollution would have been higher by 510 thousand (95% confidence interval: 360 thousand to 730 thousand) without these controls. Our analysis shows a concentration of mortality impacts in densely populated urban areas, motivating local policymakers to design stringent vehicle emission control policies. The results imply that vehicle emission control will require policy designs that are more multifaceted than traditional controls, primarily represented by the strict emission standards, with careful consideration of the challenges in coordinated mitigation of both PM2.5and O3in different regions, to sustain improvement in air quality and public health given continuing swift growth in China’s vehicle population.

Air pollution is one of the biggest challenges for human health, and this is especially true for PM2.5 pollution in developing countries like China. Much of the PM2.5 research has been conducted in urban areas, but most tourist attractions are outdoors and outside cities and have been left out of related studies, leaving tourists unaware of the deadly air. To fill this gap, we investigated monthly PM2.5 concentrations in all of China’s outdoor tourist attractions. Our results indicated that summer is the healthiest time to travel in the Northeast, South, Southwest, and Northwest of China. Without air pollution management, our results also indicated that more than one third of the outdoor attractions would become unhealthy throughout the year. Thus, our work provides medical information to suggest that all tourists schedule China travel during periods of healthy air quality and also calls for instant air pollution management in China and beyond.

Erudite groups of people, scientists, planners, and policy-makers of different countries have come to realise that quality of environment is not necessarily a simple function of nature as in primitive earth. Today nature’s self-regulatory functions are inoperative. All the developed and developing countries are deeply concerned to make balance between their environmental anxiety and their economic development. Dreadful environmental conditions are affecting the biological segment of the ecosystem of these areas. Human being, ‘one of the most precious component in biosphere’, have regular predicament situation with accretion of sullied air, water, and soil degradation. Though water and land pollution is extremely dangerous, air pollution has its own peculiarities, due to its trans-boundary dispersion of pollutants over the entire world. The effect of air pollution on health is very complex as there are many different sources and their individual effect varying from one to other. It is not only the ambient air quality in the cities but also the indoor air quality in the rural and urban areas that are causing concern.The study is confined with the health impact of deteriorating air quality in Lucknow city. The aim of the present study is also to determine the consequences of ambient air quality on health of the people in the study area.

Air Pollution Tolerance Index

Industrialization is an important aspect of a growing economy. However, rapid industrialization has caused many serious impacts on the environment. One such impact is the deteriorating air quality, especially around industries. It is said that afforestation is the best and simplest way for improving the air quality. Also, trees and plants have been increasingly used as filters for dust particles around the home, traffic roads, etc. In scientific studies, it has also been found that trees and plant leaves can be used to assess the ambient air quality by an index called the Air pollution tolerance index. A literature search has been done on the scientific database like Sciencedirect and Researchgate to review the existing knowledge of Air pollution tolerance index and to find the tolerant and sensitive species based on it so that these species can be selectively planted to assess the ambient air quality and also to develop a better green belt around refineries and industries in Assam. The study has reviewed the linkage of the impact of air pollution on leaves of plants and trees through scientific evidence. Through such scientific reviews, the most tolerant species of trees and plants were chosen with the condition that it can grow under the climatic condition of Assam. The recommendation and suggestions of tolerant tree and plant species can be used for specific species plantations for developing green belts around refineries and industries in Assam. The recommendation of sensitive species can be used for monitoring ambient air quality with reference to other standard procedures.

In Indian metropolitan cities, the extensive growth of the motor vehicles has resulted in the deterioration of environmental quality and human health. The concentrations of pollutants at major traffic areas are exceeding the permissible limits. Public are facing severe respiratory diseases and other deadly cardio-vascular diseases In India. Immediate needs for vehicular air pollution monitoring and control strategies for urban cities are necessary. Vehicular emission is the main source of deteriorating the ambient air quality of major Indian cities due to rapid urbanization. Total vehicular population is increased to 15 Lacks as per recorded data of Regional Transport Organization (RTO) till 2014-2015. This study is focused on the assessment of major air pollution parameters responsible for the air pollution due to vehicular emission. The major air pollutants responsible for air pollution due to vehicular emissions are PM10, PM2.5, Sox, Nox, HC, CO2 and CO and Other meterological parameters like Ambient temperature, Humidity, Wind direction and Wind Speed. Sampling and analysis of parameters is carried out according to National Ambient Air Quality Standards Guidelines (NAAQS) (2009) and IS 5128.
