Total volatile organic compounds (TVOCs), respiratory suspended particulate matter (RSPM-PM10), fine (FPM-PM2.5) and sub-fine (SFPM-PM1) have been found to exert negative impact on the women health. This study was conducted see effect of indoor RSPM, FPM, SFPM TVOCs health predominantly young dwellers (specifically categorized into pre-teenagers i.e., 8–12 years, teenagers 13–19 years post-teenagers 20–21 years). Indoor monitoring from November 2022 February 2023 in six different urban households Lucknow, capital city Uttar Pradesh state India. Envirotech APM 550 for RSPM 577 portable sensor-based instrument (BR-SMART) were used measure TVOCs. The highest average concentrations be 250.1 ± 14.11 µg/m3 (PM10) at Rajajipuram, 140.62 19.71 (PM2.5) Indranagar, 27.60 1.87 (PM1) 934 70.41 (TVOCs) Kaiserbagh.Health risk assessment also determined using daily dose (ADD), excess lifetime cancer (ELCR) hazard quotient (HQ) carcinogenic non-carcinogenic risk.

Wildfires in North America, particularly western states, have caused widespread environmental, economic, social, and health impacts. Smoke from these fires travels long distances, spreading pollutants worsening the air quality across continents. Vulnerable groups, such as children, elderly, those with preexisting conditions, face heightened risks, do firefighters working extreme conditions. Wildfire are of particular concern they fighting conditions minimal protective equipment. This study examined wildfire smoke during July–August 2021, when intense Canada U.S. led to cross-continental transport significant impacts on America. Using GEOS-Chem model, we simulated distribution PM2.5 (particulate matter a diameter 2.5 μm or smaller), identifying carcinogenic risks for adults, using dosimetry risk methodologies established by EPA. Significant adult, child, firefighter populations due exposure were identified over two-month period evaluation. The findings emphasize need future studies assess toxic chemical mixtures consider underrepresented communities.
