Transitioning from climate ambitions to climate actions through public health policy initiatives

Environmental Epidemiology, Год журнала: 2025, Номер 9(2), С. e373 - e373

Опубликована: Март 6, 2025

Policies to implement climate-forcing pollution emission reductions have often been stymied by economic and political divisiveness. However, certain uncontested nonregret public health policies that also carry cobenefits with them could provide more achievable policy pathways accelerate the implementation of climate mitigation. An International Society for Environmental Epidemiology Policy Committee endorsed pre-28th Conference Parties meeting workshop brought together experts on environment, diet, civic planning, review current understanding approaches change mitigation reducing greenhouse gas emissions. Promising areas identified as providing included: improving air quality through stronger regulation harmful combustion-related pollutants, advancing healthier plant-based food procurement programs, promoting sustainable transport options, developing infrastructure (e.g., combustion-free buildings), use forcing substances in healthcare. It is concluded cities, states, nations, when aided involved professionals, can advance many practical health, planning improve well-being will serve translate ambitions into action.

The Impact of Indoor Environments on the Abundance of Urban Outdoor VOCs

Environmental Science & Technology, Год журнала: 2025, Номер unknown

With the upcoming transition to clean electric vehicles, sources of volatile organic compounds (VOCs) in ambient environment are rapidly changing and highly uncertain. Here, through systematic characterization emissions from a typical apartment Chinese megacity (Shenzhen), we show that indoor environments contribute significantly levels (i.e., outdoor) VOCs. In particular, observe majority VOCs originate unoccupied spaces, demonstrating temperature-dependent release surface reservoirs. The total indoor-to-outdoor VOC emission rates varied 53 2300 mg day–1 (median 230 day–1) during periods, influenced by both air exchange rate temperature. Reanalysis literature data various building studies worldwide corroborates our findings reveals scale with room volume, an average 0.33 ± 0.03 h–1 m–3. Our study implies urban levels, rivaling traditional sources, e.g., power generation biomass burning. This is particularly true for oxygenated VOCs, such as methanol, amounting ∼60% transportation emissions. change understanding role contributions outdoor quality, whose importance will increase controls on industrial intensify.

Time trends in disability-adjusted life years for cataracts attributable to indoor air pollution across 17 low- and middle-income countries

Indoor air pollution (IAP) is a risk factor leading to cataracts. The disease burden of cataracts due IAP currently greater in low- and middle-income countries, an in-depth analysis necessary track the current time trend caused by countries.

Effect of operating conditions and technology on residential wood stove emissions of criteria, greenhouse gas, and hazardous air pollutants

Journal of the Air & Waste Management Association, Год журнала: 2025, Номер unknown

Опубликована: Апрель 15, 2025

Pollution from cordwood stoves includes fine particulate matter (PM), hazardous air pollutants (HAPs), greenhouse gases (GHGs), and other compounds that impact human health climate. To better understand emissions under typical homeowner use patterns, we tested five U.S. (four meeting 2020 New Source Performance Standards (NSPS) one pre-NSPS, circa 1980 stove) across three technology types using the novel Integrated Duty Cycle (IDC) protocol. We report factors by IDC phase, which represent "real world" operating conditions (such as "start-up," "high heat," "overnight burn") fuel loading patterns. evaluated effect of dry burn rate on PM, HAP GHG determined significant effects phase in uncertified catalytic/hybrid stove emissions, but not noncatalytic stoves. This has important implications for quality science, policy, design, different climate zones will influence number starts, frequencies phases.

Partitioning of Neutral PFAS in Homes and Release to the Outdoor Environment: Results from the IPA Campaign

Environmental Science & Technology, Год журнала: 2024, Номер 58(42), С. 18870 - 18880

Опубликована: Окт. 10, 2024

The distribution and fate of per- polyfluoroalkyl substances (PFAS) in homes are not well understood. To address this, we measured nine neutral PFAS dust, airborne particles, dryer lint, on heating air conditioning (HAC) filters 11 North Carolina as part the Indoor Assessment (IPA) Campaign compared them with concurrently collected gas cloth measurements. Fluorotelomer alcohols (FTOHs) contributed most (≥75%) to total (∑) concentrations HAC filter, lint samples, mean ∑(FTOH) 207 ng/g, 549 84 respectively. In perfluorooctane sulfonamidoethanols (FOSEs) dominated, a ∑(FOSE) concentration 0.28 ng/m
