Sea Lord Containers Ltd. dated 05/02/2019 regarding air pollution in the outskirts of Mumbai affecting inhabitants of the area, particularly at villages Ambapada and Mahul since 2007 on account of business of logistic services storing oil, gas and chemical items as well as oil companies doing similar activities.

Air pollution is a major planetary health risk, with India estimated to have some of the worst levels globally. To inform action at subnational levels in India, we estimated the exposure to air pollution and its impact on deaths, disease burden, and life expectancy in every state of India in 2017.

Order of the National Green Tribunal in the matter of Subhas Datta Vs State of West Bengal & Others dated 27/11/2018 regarding the alarming adverse air quality of Kolkata City which was stated to be highly polluted during the period commencing from mid-October to February end. The principal reason for the bad ambient air quality in the city of Kolkata and Howrah was identified to be auto emission apart from road dust, construction activities, burning of municipal waste and industrial wastes including plastics, population of DG sets and industrial emissions.

Order of the National Green Tribunal in the matter of Aditya N. Prasad & Others Vs Union of India & Others dated 01/11/2018 regarding installation of Stage-I and Stage-II Vapor Recovery Devices (VRDs) at all fuel stations, distribution centers, terminals, railway loading/unloading facilities and airports in the National Capital Territory of Delhi. Such devices are required to safeguard against Volatile Organic Compounds (VOC) released in the process of transfer of petroleum products.

Nearly 60% of U.S. children live in counties with PM2.5 concentrations above air quality standards. Understanding the relationship between ambient air pollution exposure and health outcomes informs actions to reduce exposure and disease risk.

Ambient air pollution is a major health risk globally. To reduce adverse health effects on days when air pollution is high, government agencies worldwide have implemented air quality alert programmes. Despite their widespread use, little is known about whether these programmes produce any observable public-health benefits. We assessed the effectiveness of such programmes using a quasi-experimental approach.

Many policy interventions intended to benefit public health can only be evaluated as so-called natural experiments, because implementation is not controlled by researchers seeking to assess effectiveness. Such assessments can be complicated by non-comparability between people affected and not affected by the intervention. Various quasi-experimental designs have been proposed to address this problem of non-comparability, one being the regression discontinuity design, which has had little use in public health.

Few large multicity studies have been conducted in developing countries to address the acute health effects of atmospheric ozone pollution. The researchers explored the associations between ozone and daily cause-specific mortality in China.

Urban air quality in most megacities has been found to be critical and Kolkata Metropolitan City is no exception to this. An analysis of ambient air quality in Kolkata was done by applying the Exceedance Factor (EF) method, where the presence of listed pollutants’ (RPM, SPM, NO2, and SO2) annual average concentration are classified into four different categories; namely critical, high, moderate, and low pollution.
