We all are living in such a world where the pollution and global warming are threats. Every year in India, at the time of festival seasons of Dussehra and Deewali, the smog and pollution are so much that millions of people suffer from different health issues. Also, the farmers of Punjab and Hariyana burn the Parali of their crops due to less awareness, and it becomes a challenge in the national capital, Delhi, to breathe. The government invests resources and the vehicles are allowed as per their even odd numbers. The authors team, including government officials, educationists, academicians, and students, along with IT experts, performed significant experiments on the ancient Indian Vedic science of Yajna and Mantra, and they found surprising results in the reduction of pollution on respective days. The chapter is an effort to present that scientific study conducted in 2018 and 2019 in random days after doing Yajna, and it was found that the pollution level was drastically decreased.

Risk Of Death

South Asia is at the epicenter of the global air pollution problems and still evolving in COVID-19 cases and fatalities. There is growing evidence of increased rates of COVID-19 in areas with high levels of air pollution. Air pollution is found to cause cellular damage and inflammation throughout the body and has been linked to higher rates of diseases, including cancer, heart disease, stroke, diabetes, asthma, and other comorbidities. All these conditions also potentially increase the risk of death in COVID-19 patients. The causal link between the exposure to air pollution and COVID-19 is still under investigation around the world, underpinned by rigorous scientific research and peer-review processes. However, in terms of the approach after a careful review of the literature, the instrumental variable (IV) approach is a prospective candidate to establish causality in a reduced-form analysis to overcome endogeneity and measurement errors of air pollution level. An analysis, therefore, using sufficiently anonymized individual and household level information on COVID-19, household air pollution, and other individual and household socioeconomic endowments in the same primary sampling unit (PSU) of the individual and household survey would be necessary to establish the causality. The PSU data are usually available from demographic health surveys (DHS) with randomly displaced location information to maintain anonymity. Also, for the instrument of the exposure to ambient air pollution, the use of thermal inversions is suggested conditional on weather-related variables—for example, temperature, precipitation, wind velocity and direction, and humidity.

Abstract. Beijing, as a representative megacity in China, is experiencing some of the most severe air pollution episodes in the world, and its fast urbanization has led to substantial urban and peri-urban disparities in both health status and air quality. Uncertainties remain regarding the possible causal links between individual air pollutants and health outcomes, with spatial comparative investigations of these links lacking, particularly in developing megacities. In light of this challenge, Effects of AIR pollution on cardiopuLmonary disEaSe in urban and peri-urban reSidents in Beijing (AIRLESS) was initiated, with the aim of addressing the complex issue of relating multi-pollutant exposure to cardiopulmonary outcomes. This paper presents the novel methodological framework employed in the project, namely (1) the deployment of two panel studies from established cohorts in urban and peri-urban Beijing, with different exposure settings regarding pollution levels and diverse sources; (2) the collection of detailed measurements and biomarkers of participants from a nested case (hypertensive) and control (healthy) study setting; (3) the assessment of indoor and personal exposure to multiple gaseous pollutants and particulate matter at unprecedented spatial and temporal resolution with validated novel sensor technologies; (4) the assessment of ambient air pollution levels in a large-scale field campaign, particularly the chemical composition of particulate matter. Preliminary results showed that there is a large difference between ambient and personal air pollution levels, and the differences varied between seasons and locations. These large differences were reflected on the different health responses between the two panels.

Vehicular traffic contributes significantly to the pollution of air and neighborhood noise. Since there is increasing affirmation that ambient air pollution hurts reproductive health, which is less known regarding the relationship between traffic noise and pregnancy outcomes. Many researchers have investigated all the possible adverse effects of ambient air pollution on birth outcomes during the last decade or so. We examined these studies, which were discovered by thoroughly searching the major scientific databases. Overall, research suggests that air pollution and noise pollution significantly impact birth outcomes, while the quality of the deposition varies. Researchers utilized connected administrative health data sources to discover pregnancy outcomes with detailed covariate data (gender, contemporary lifestyle, total no of pregnancies, birth month and year, and so on), earnings and education, and mother housing history. Using the deterministic model (CadnaA) and air pollutants exposure, they assessed noise exposure during pregnancy by assessing temporally adjusted land-use regression. Noise exposure is related to reduced birth weight. We also looked into various processes to prevent air pollution and noise. As a result of the policy change and technical innovation, the government, authorities, and industry have been at the forefront of combating pollution. Pollution levels in and around people's homes and workplaces are typically beyond their control. However, few things may be done to mitigate the impacts of contaminated air.

Ambient (outdoor) air pollution is now recognized as an important problem, both nationally and worldwide. Our scientific understanding of the spectrum of health effects of air pollution has increased, and numerous studies are discovering important health effects from air pollution at levels once considered safe. Elderly, children and infants are among the most susceptible to many of the air pollutants. In addition to associations between air pollution and respiratory symptoms, asthma exacerbations, and asthma hospitalizations, recent studies have found links between air pollution and preterm birth, infant mortality, deficits in lung growth, and possibly, development of asthma. This paper summarizes the recent literature linking ambient air pollution to adverse health outcomes in population and includes a perspective on the current regulatory process. The review provides advice to pediatricians on how to integrate issues regarding air quality and health into patient education and patients' environmental health advocacy and concludes with recommendations to the government on promotion of effective air-pollution policies to ensure protection of our health.   DOI: 10.3329/bjpp.v22i1.3566 Bangladesh J Physiol Pharmacol 2006; 22(1/2) : 25-28

Background: Tuberculosis remains a major global health problem with 10.4 million incident cases in 2016. Although Mycobacterium tuberculosis is the causative agent, many environmental factors play a role in disease progression. Several respiratory hazards including smoking and indoor air pollution were suggested to increase the risk of tuberculosis, but only fewer studies has been conducted on the association between ambient air pollution and tuberculosis.Methods: Data on ambient air quality levels (annual mean concentration of particulate matter 2.5 µg/m3) for the year 2016 was collected from the World Health Organization (WHO) data base for 190 countries which comprises of 6 WHO regions. Similarly data on incidence and mortality rate of tuberculosis for the year 2016 was collected for the above countries from the WHO data base. The data were tabulated and statistical analysis was performed using Pearson’s correlation coefficient model to examine the association of annul mean concentration of particulate matter 2.5 with incidence and mortality rates of tuberculosis.Results: Incidence and mortality rates of tuberculosis were found to be increasing with increasing levels of air pollution. It was correlated using scatter plot. Pearson’s correlation coefficient for air pollution level and incidence of tuberculosis was 0.331 (95% CI: 0.435-0.883), (p<0.001), and for tuberculosis mortality was 0.39 (95% CI: 0.525-0.906) (p<0.001).Conclusions: The study suggests there is a significant positive relationship between ambient air pollution level and tuberculosis incidence and mortality rates.

ObjectiveTo investigate the association between ambient air pollution and stroke morbidity in different subgroups and seasons.MethodsWe performed a time-series analysis based on generalised linear models to study the short-term exposure–response relationships between air pollution and stroke hospitalisations, and conducted subgroup analyses to identify possible sensitive populations.ResultsFor every 10 µg/m3increase in the concentration of air pollutants, across lag 0–3 days, the relative risk of stroke hospitalisation was 1.029 (95% CI 1.013 to 1.045) for PM2.5, 1.054 (95% CI 1.031 to 1.077) for NO2and 1.012 (95% CI 1.002 to 1.022) for O3. Subgroup analyses showed that statistically significant associations were found in both men and women, middle-aged and older populations, and both cerebral infarction and intracerebral haemorrhage. The seasonal analyses showed that statistically significant associations were found only in the winter.ConclusionsOur study indicates that short-term exposure to PM2.5, NO2and O3may induce stroke morbidity, and the government should take actions to mitigate air pollution and protect sensitive populations.

Large cities in China are experiencing severe ambient air pollution. Although China accounts for more than 45% of new cases of nasopharyngeal carcinoma worldwide in 2018, few studies have examined the association between ambient air pollution and the high nasopharyngeal carcinoma (NPC) incidence in China. Thus, we aim to investigate whether exposure to ambient air pollution (including nitrogen dioxide, sulfur dioxide, and PM10) would significantly affect NPC incidence in large Chinese cities. We collected panel data of ten Chinese provincial cities about local NPC incidence, air pollution level, meteorology, and city profiles during 2006 to 2013 to construct a two-way fixed-effects model to explore the association between ambient air pollution and NPC incidence, as well as possible regional and gender differences behind the association. We found that NO2 had the strongest association with NPC incidence, and the relative risks were 2.2995 (95% CI, 1.2567–4.2075) for males and 1.3010 (95% CI, 0.8212–2.0620) for females, respectively. Under cumulative exposure, it was still NO2 that had the strongest association with NPC incidence, with a relative risk of 1.8836 (95% CI, 1.2416–2.8577), compared to 1.0857 (95% CI, 0.9474–1.2450) and 1.0547 (95% CI, 0.8790–1.2663) for SO2 and PM10, respectively. In addition, males were found more sensitive to ambient air pollution than females. We also found that southern Chinese cities were more sensitive to NO2 than northern cities, which might be related to a higher humidity there. Our study reveals that exposure to ambient air pollutants like SO2, PM10, and particularly NO2, is significantly positively associated with NPC incidence in China.

Harmful Effects

Air pollution is an issue that is out of the control of an average citizen. Controlling air pollution requires preventive and control measures on a large scale implemented by the government. However, what an individual can dois protect him/her from the harmful effects of pollution by taking precautions such as not going out in times of severe pollution or wearing an air mask when travelling out. It will be very helpful if a person is able to find out the pollution level around him. Government provides measures of pollution in terms of AIR QUALITY INDEX (AQI). However this is provided only at certain centre places. AQI may change drastically between these centres. In this report, an effort was made to solve this problem by enabling an individual to find an estimate of the Air Quality Index near them with their smartphone, even without an Internet connection, by simply clicking an image of their surroundings. Using this information a person can take preventive measures to take care of his health. This will not only spread awareness about air pollution but also protect people from the harmful effects of air pollution. We have used Machine Learning to achieve this goal. We prepared a dataset of images of sky and trained a model using several algorithms and compared them. We then used this model to recognise almost accurate AQI of the surroundings.
