Nationwide analysis of air pollution hotspots across India: A spatiotemporal PM trend analysis (2008-2019).

Introduction: India experiences high levels of air pollution as measured by fine particulate matter <2.5 μm (PM) across the country. With limited resources, it is imperative to identify the most impacted areas.

Health effects of selected environmental Exposomes Across the Life courSe in Indian populations using longitudinal cohort studies: GEOHealth HEALS Study protocol.

Introduction: Air pollution presents a major public health threat to India, affecting more than three quarters of the country's population. In the current project, GEOHealth Health Effects of Selected Environmental Exposomes Across the Life CourSe-India, we aim to study the effect of environmental exposomes-fine particulate matter (PM), nitrogen dioxide (NO), ozone (O) and extremes of temperature-on multiple health outcomes using a modified life course approach. The associated training grant aims to build capacity in India to address the unique environmental health problems.

Longitudinal associations between ambient PM exposure and lipid levels in two Indian cities.

Background: Exposure to ambient PM is known to affect lipid metabolism through systemic inflammation and oxidative stress. Evidence from developing countries, such as India with high levels of ambient PM and distinct lipid profiles, is sparse.

Methods: Longitudinal nonlinear mixed-effects analysis was conducted on >10,000 participants of Centre for cArdiometabolic Risk Reduction in South Asia (CARRS) cohort in Chennai and Delhi, India.

Nationwide estimation of daily ambient PM from 2008 to 2020 at 1 km in India using an ensemble approach.

High-resolution assessment of historical levels is essential for assessing the health effects of ambient air pollution in the large Indian population. The diversity of geography, weather patterns, and progressive urbanization, combined with a sparse ground monitoring network makes it challenging to accurately capture the spatiotemporal patterns of ambient fine particulate matter (PM) pollution in India. We developed a model for daily average ambient PM between 2008 and 2020 based on monitoring data, meteorology, land use, satellite observations, and emissions inventories.

Personal exposure to fine particulate matter concentrations in central business district of a tropical coastal city.

Unlabelled: In the present study, personal exposure to fine particulate matter (particulate matter with an aerodynamic diameter <2.5 μm [PM]) concentrations in an urban hotspot (central business district [CBD]) was investigated. The PM monitoring campaigns were carried out at an urban hotspot from June to October 2015.
