Nearly 3 billion people worldwide rely on solid fuel combustion to meet basic household energy needs. The resulting exposure air pollution causes an estimated 4.5% of the global burden disease. Large variability and a lack resources for research development have resulted in highly uncertain estimates.We sought identify priorities assessment that will more accurately precisely define exposure-response relationships necessary inform future cleaner-burning cookstove dissemination programs.As...
Prescribed burning is a significant source of fine particulate matter (PM2.5) in the southeastern United States. However, limited data exist on emission characteristics from this source. Various organic and inorganic compounds both gas particle phase were measured emissions prescribed burnings conducted at two pine-dominated forest areas Georgia. The measurements volatile (VOCs) PM2.5 allowed determination factors for flaming smoldering stages burnings. VOC distinctly higher than those...
Exposure to air pollution and, more specifically, particulate matter (PM) is associated with adverse health effects. However, the specific PM characteristics responsible for biological effects have not been defined.In this project we examined composition, sources, and relative toxicity of samples aerodynamic diameter </= 2.5 microm (PM2.5) collected from sites within Southeastern Aerosol Research Characterization (SEARCH) monitoring network during two seasons. These represent four areas...
Over 40% of the world's population relies on solid fuels for heating and cooking. Use improved biomass cookstoves (ICS) has potential to reduce household air pollution (HAP). As part an evaluation identify ICS use in Kenya, we collected indoor personal samples assess differences between traditional (TCS) ICS. We conducted a cross-over study 2012 two Kenyan villages; up six different were installed 45 households during two-week periods. Forty-eight hour kitchen measurements fine particulate...
Background: Exposure to PM2.5 arising from solid fuel combustion is estimated result in ∼2.3 million premature deaths and 91 lost disability-adjusted life years annually. Interventions attempting mitigate this burden have had limited success reducing exposures levels thought provide substantive health benefits. Objectives: This paper reports exposure reductions achieved by a liquified petroleum gas (LPG) stove intervention for pregnant mothers the Household Air Pollution Intervention Network...
Household air pollution (HAP) from solid fuel use is associated with adverse birth outcomes, but data for exposure-response relationships are scarce. We examined associations between HAP exposures and birthweight in rural Guatemala, India, Peru, Rwanda during the Air Pollution Intervention Network (HAPIN) trial.
Household air pollution is associated with stunted growth in infants. Whether the replacement of biomass fuel (e.g., wood, dung, or agricultural crop waste) liquefied petroleum gas (LPG) for cooking can reduce risk stunting unknown.
Kitchen-area 22-h gravimetric PM2.5 and passive diffusion stain-tube carbon monoxide (CO) concentrations were measured in homes with open fire improved wood cookstoves two studies. In the first study (Guat-2), which also studied gas cookstoves, three samples collected per stove condition from each of test houses. second (Guat-3), one sample was house 15 25 improved-stove CO personal taken for mother child both Spearman correlation coefficients (R) between kitchen-area levels using fires or...
Area 22-h average carbon monoxide (CO), total suspended particulates (TSP), particles less than 10 microns in diameter (PM10), and 2.5 (PM2.5) measurements were made three test homes of highland rural Guatemala kitchens, bedrooms, outdoors on a longitudinal basis, i.e. before after introduction potential exposure-reducing interventions. Four cookstove conditions studied sequentially: background (no stove use); traditional open woodstove, improved woodstove with flue (plancha), bottled-gas...
Abstract Extreme heat is the leading weather-related killer in United States. Vulnerability to extreme has previously been identified and mapped urban areas improve morbidity mortality prevention efforts. However, only limited work examined vulnerability outside of locations. This study seeks broaden geographic context earlier compute across state Georgia, which offers diverse landscapes populations with varying sociodemographic characteristics. Here, a modified index (HVI) developed by Reid...
BACKGROUND: High quality personal exposure data is fundamental to understanding the health implications of household energy interventions, interpreting analyses across assigned study arms, and characterizing exposure-response relationships for air pollution.This paper describes collection Household Air Pollution Intervention Network (HAPIN), a multicountry randomized controlled trial liquefied petroleum gas stoves fuel among 3,200 households in India, Rwanda, Guatemala, Peru.OBJECTIVES: The...
Exposure during pregnancy to household air pollution caused by the burning of solid biomass fuel is associated with adverse health outcomes, including low birth weight. Whether replacement a cookstove liquefied petroleum gas (LPG) would result in an increase weight unclear.
Twenty-four-hour samples of PM10 (mass particles with aerodynamic diameter < or = 10 microm), PM2.5, 2.5 particle strong acidity (H+), sulfate (SO42-), nitrate (NO3-), ammonia (NH3), nitrous acid (HONO), and sulfur dioxide were collected inside outside 281 homes during winter summer periods. Measurements also conducted periods at a regional site. A total 58 nonsmokers sampled the 223 Seventy-four reported use kerosene heater. All in located southwest Virginia. but 20 Virginia; remainder...
Wildland firefighters in the United States are occupationally exposed to high levels of woodsmoke. Results from experimental studies show that exposure woodsmoke induces inflammation. A study was conducted investigate effect occupational on inflammatory biomarkers working at prescribed burns. Twelve U.S. Forest Service wildland Savannah River Site, South Carolina, volunteered give blood samples during four burns between February and March 2011. Twenty-four paired (pre- post-work shift) were...
