Article Synopsis
- - The study evaluated the link between school greenness and academic performance in 281,695 fourth-grade students from various school types in Santiago, Chile, revealing that greener schools were tied to better standardized test scores in mathematics and reading.
- - A 0.1 increase in greenness was associated with a notable increase in math (36.9 points) and reading (1.84 points) scores, as well as higher chances of meeting learning standards, especially in public schools.
- - Findings suggest that enhancing greenness in schools could help improve education outcomes and reduce educational inequalities in urban settings, particularly for students in public schools.
We provide a novel method to assess the heat mitigation impacts of greenspace though studying the mechanisms of ecosystems responsible for benefits and connecting them to heat exposure metrics. We demonstrate how the ecosystem services framework can be integrated into current practices of environmental health research using supply/demand state-of-the-art methods of ecological modeling of urban greenspace. We compared the supply of cooling ecosystem services in Boston measured through an indicator of high resolution evapotranspiration modeling, with the demand for benefits from cooling measured as a heat exposure risk score based on exposure, hazard and population characteristics.

Spatially linking social and environmental exposures to electronic health records (EHR) can aid exposure assessment, epidemiology, and clinical treatment, but EHR data on exposures are missing for many children with asthma. To address the issue, we predicted presence of indoor asthma trigger allergens, and estimated effects of their key geospatial predictors.

- The Normalized Difference Vegetation Index (NDVI) measures greenness and is critical in environmental health studies, but its impact on exposure assessment is not fully understood.
- The study analyzed greenness exposure for over 31,000 children in Boston, using NDVI data from different satellite resolutions to assess how spatial resolution affects exposure misclassification.
- Results indicated that coarser NDVI resolutions led to greater greenness estimates but similar exposure distributions, with higher misclassification rates linked to more significant resolution differences and smaller buffer zones.
To further the understanding and implementation of expert elicitation methods in the evaluation of public policies related to air pollution, the present study's main goal was to explore the potential strengths and weaknesses of structured expert judgment (SEJ) methodology as a way to derive a C-R function for chronic PM(2.5) exposure and premature mortality in Chile. Local experts were classified in two groups according to background and experience: physicians (Group 1) and engineers (Group 2).
