“…Similar to other studies (e.g. [24,26,[31][32][33]), we found that exposure levels varied among the selected occupations and even within occupation depending on nature, time, duration and location of work. Average PM 2.5 exposure was relatively higher in rickshaw drivers and street vendors with average eight hours of exposure value of 68±27.9 μg m −3 and 66.6±33.9 μg m −3 respectively.…”

Urban populations in South Asia are regularly exposed to poor air quality, especially elevated concentrations of fine particulate matter (PM2.5). However, the potential differential burden for the urban poor has received little attention. Here, we evaluate the links between occupation, patterns of exposure to PM2.5, and the impacts at an individual and household level for vulnerable populations in Lahore (Pakistan), Kathmandu (Nepal), and Mandalay (Myanmar). We conduct personal exposure measurements and detailed interviews, identifying a wide range of impacts at individual and household levels. Low-income populations are concentrated in occupations that expose them to higher concentrations. Individuals report a range of adverse health impacts and limited capacities to reduce exposure. The lost income, compounded with the costs of managing these health impacts and limited opportunities for alternative employment, can deepen the socioeconomic vulnerability for the household. Reducing these risks requires targeted interventions such as improved social safety nets.

“…Researchers have employed monitored data (fixed monitors, mobile monitors and sensors) (Kumar et al, 2015;Menon and Nagendra, 2018), satellite data (Chitranshi et al, 2015;Mahapatra et al, 2019), modeling and combined approaches (Xie et al, 2017;Mandal et al, 2020) to identify air pollution hotpots within the cities.…”

The urban population is subjected to multiple exposures of air pollution and heat stress and bear severe impacts on their health and well-being in terms of premature deaths and morbidity. India tops the list of countries with the highest air pollution exposure and hosts some of the most polluted cities in the world. Similarly, Indian cities are highly vulnerable to extreme heat with the frequency of heatwaves expected to increase several-fold in urban areas in India. It is reported that mitigating air pollution could reduce the rural-urban difference of the incoming radiation thus resulting in mitigation of the urban heat island effect. Since the interaction between urban heat and air pollution is dynamic and complex, both these factors should be considered by the urban authorities in designing mitigation strategies. Given the multi-functional nature and cost-effectiveness of Nature-Based Solutions (NbS), they appear to be the most appropriate remedy for environmental issues of urban areas, particularly in developing countries. In addition to improving public health (through the reduction in air pollution and urban heat), NbS also provides a wide range of co-benefits such as reducing energy cost and health costs as well as conservation of biodiversity. This review is an attempt to understand the potentials of NbS in co-mitigating air pollution and urban heat in Indian cities. A framework for the planning and design of NbS in Indian cities is also proposed based on the review that could help city planners and decision-makers in addressing these two issues in an integrated manner.

“…At industrial and high traffic areas, it changes spatially within meters and over time within hours. For example, Menon et al, reported a change in particulate concentration at high business streets during the morning, afternoon and evening for a tropical coastal city in India [ 14 ]. Citizen science applications such as personal exposure monitoring and occupational exposure monitoring need high spatial and temporal resolutions [ 15 , 16 ].…”

Low-cost sensors (LCS) are becoming popular for air quality monitoring (AQM). They promise high spatial and temporal resolutions at low-cost. In addition, citizen science applications such as personal exposure monitoring can be implemented effortlessly. However, the reliability of the data is questionable due to various error sources involved in the LCS measurement. Furthermore, sensor performance drift over time is another issue. Hence, the adoption of LCS by regulatory agencies is still evolving. Several studies have been conducted to improve the performance of low-cost sensors. This article summarizes the existing studies on the state-of-the-art of LCS for AQM. We conceptualize a step by step procedure to establish a sustainable AQM setup with LCS that can produce reliable data. The selection of sensors, calibration and evaluation, hardware setup, evaluation metrics and inferences, and end user-specific applications are various stages in the LCS-based AQM setup we propose. We present a critical analysis at every step of the AQM setup to obtain reliable data from the low-cost measurement. Finally, we conclude this study with future scope to improve the availability of air quality data.
