The study, titled ‘'Health impact assessment of Delhi's outdoor workers exposed to air pollution and extreme weather events: an integrated epidemiology approach' assessed the workers for breathing difficulties or acute lung function impairment; irregular heartbeats & chest discomfort; back, shoulder, and joint pains; redness of eyes and irritation, and finally, skin rashes, headaches & overall weakness, both in winters and summers. It is published in Springer's Environment Science and Pollution Research.
