“…4), indirect exposure measurements tended to have less bias and agree better with direct personal exposure than kitchen area PM 2.5 measurements. Therefore, the Beacon indirect exposure method described here better estimates exposures than does simply using area measurements as a proxy for exposure, a common, but perhaps inaccurate, method used to estimate PM 2.5 exposures for infants [27,28]. Our findings confirm other recent data from HAPIN formative research indicating that the LPG intervention can reduce PM 2.5 levels close to the WHO target of 35 µg/m 3 .…”

Household air pollution (HAP) generated from solid fuel combustion is a major health risk. Direct measurement of exposure to HAP is burdensome and challenging, particularly for children. In a pilot study of the Household Air Pollution Intervention Network (HAPIN) trial in rural Guatemala, we evaluated an indirect exposure assessment method that employs fixed continuous PM 2.5 monitors, Bluetooth signal receivers in multiple microenvironments (kitchen, sleeping area and outdoor patio), and a wearable signal emitter to track an individual's time within those microenvironments. Over a four-month period, we measured microenvironmental locations and reconstructed indirect PM 2.5 exposures for women and children during two 24-h periods before and two periods after a liquefied petroleum gas (LPG) stove and fuel intervention delivered to 20 households cooking with woodstoves. Women wore personal PM 2.5 monitors to compare direct with indirect exposure measurements. Indirect exposure measurements had high correlation with direct measurements (n = 62, Spearman ρ = 0.83, PM 2.5 concentration range: 5-528 µg/m 3). Indirect exposure had better agreement with direct exposure measurements (bias: −17 µg/m 3) than did kitchen area measurements (bias: −89 µg/m 3). Our findings demonstrate that indirect exposure reconstruction is a feasible approach to estimate personal exposure when direct assessment is not possible.

“…Based on the background literature review, roundtable discussions, and a participatory workshop documented in the issue brief, the conceptual model is premised on several factors: Air pollution poses a significant public health risk [ 50 ]; this risk is under-recognized by the public; air pollution is inadequately monitored and managed [ 65 ]; and documenting air quality through an AQI and communicating specific exposure mitigation strategies can improve public health and facilitate long-term improvement of air quality [ 25 , 51 , 66 ]. Another underlying premise is that certain populations are at greater risk to air pollution-related health effects because of relatively high exposures (e.g., occupational exposures among outdoor workers, including traffic police, construction workers, and street vendors, among others [ 42 , 67 , 68 ]) or low coping capacity (e.g., school children, patients with pre-existing respiratory illnesses [ 69 , 70 , 71 ]). The model also posits that strategies for conveying risk information and corresponding exposure mitigation recommendations would reduce the population health risks related to air pollution [ 66 ].…”

Indian cities struggle with some of the highest ambient air pollution levels in the world. While national efforts are building momentum towards concerted action to reduce air pollution, individual cities are taking action on this challenge to protect communities from the many health problems caused by this harmful environmental exposure. In 2017, the city of Ahmedabad launched a regional air pollution monitoring and risk communication project, the Air Information and Response (AIR) Plan. The centerpiece of the plan is an air quality index developed by the Indian Institute of Tropical Meteorology’s System for Air Quality and Weather Forecasting and Research program that summarizes information from 10 new continuous air pollution monitoring stations in the region, each reporting data that can help people avoid harmful exposures and inform policy strategies to achieve cleaner air. This paper focuses on the motivation, development, and implementation of Ahmedabad’s AIR Plan. The project is discussed in terms of its collaborative roots, public health purpose in addressing the grave threat of air pollution (particularly to vulnerable groups), technical aspects in deploying air monitoring technology, and broader goals for the dissemination of an air quality index linked to specific health messages and suggested actions to reduce harmful exposures. The city of Ahmedabad is among the first cities in India where city leaders, state government, and civil society are proactively working together to address the country’s air pollution challenge with a focus on public health. The lessons learned from the development of the AIR Plan serve as a template for other cities aiming to address the heavy burden of air pollution on public health. Effective working relationships are vital since they form the foundation for long-term success and useful knowledge sharing beyond a single city.

Developing fetus is connected to the mother by placenta to receive oxygen and nutrients. Maternal exposure to ambient air pollution not only affects maternal health but also provides a pathway for many toxic pollutants to cross the placental barrier and interrupt biochemical milieu. There are numerous scientific studies available describing possible negative health impact of air pollutants on reproductive health, pregnancy outcomes and fetal development yet no toxic effect is available recently. Studying the pollutants exposure effect on fetal development is crucial for the underlying mechanism between prenatal exposure and pregnancy outcomes. Present review meticulously provides the compiled data of 40 most recent studies with possible action mechanism of air pollutants on pregnancy outcomes and fetal development to find a better solution to exterminate or reduce the problem.
