Health damages and disparities from municipal and medical waste incineration in Baltimore, USA.
Article in medRxiv : the preprint server for health sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Waste incineration in Baltimore, USA, involves two major facilities: a municipal solid waste incinerator (WIN Waste) and the nation's largest medical waste incinerator (Curtis Bay Medical Waste Incinerator). Both operate in socio-economically disadvantaged communities, raising concerns about cumulative environmental exposures and health disparities from hazardous air pollutants. Methods: We estimated health impacts from available criteria incinerator emissions data (PM, NOx, SO Findings: In 2024, the WIN Waste incinerator caused an estimated $53.8 million in health damages in Maryland and Washington DC. On average, the Curtis Bay Medical Waste Incinerator releases black smoke emissions for 52.5 minutes/day, a regulatory violation. The facility causes $36.9 million/year in health damages and is permitted to burn enough waste to cause up to $107.1 million/year; enforcing pollution controls at this site could prevent $13.8 million in annual harm in Baltimore. Combined, the two incinerators cause $97.0 million in damages annually. All-cause mortality from incinerator pollution was more common in communities with higher socioeconomic vulnerability. Interpretation: Despite being required to install new pollution control equipment following community and regulatory pressure, the WIN Waste incinerator still causes significant health damages to Maryland and Washington DC. Meanwhile, repeated black smoke emissions from the Curtis Bay incinerator indicate that ongoing, uncontrolled pollution is also a major threat to public health in the region. Health damages from these incinerators disproportionately affect communities least able to bear the economic burden. Our conservative estimates highlight the need for urgent policy reforms, including stricter emissions monitoring, phasing out non-essential incineration, and ongoing cumulative impact assessments.
