TL;DR: The goal of this study was to examine the association between park proximity, park type, and park features and physical activity in adolescent girls, and found that the type, number, and specific parks features were associated with girls' nonschool metabolic equivalent–weighted moderate/vigorous physical activity.

TL;DR: This study evaluated the relative accuracy of eight kriging methods for predicting contaminant and water quality variables measured in an urbanized estuary in South Carolina and suggested that the integration of Geographic Information System (GIS)-based network analysis with kriged using in-water distances merits further research.

TL;DR: In this article, the authors tested the hypothesis that census tracts with elevated groundwater uranium and more frequent groundwater use have increased cancer incidence and found that the hypothesis was not supported by the available evidence.

TL;DR: Fixed imputation methods seemed to yield greatest accuracy at the individual level, suggesting use for studies on area-level environmental exposures, and random methods seemed superior, as they most closely replicated the true spatial distribution.

TL;DR: The extent and magnitude of antibiotics in the environment was assessed and four antibiotics were identified as higher risks for concern based upon this approach, but only Triclosan had MEC/NOEC ratios >1 and was recommended for monitoring in future studies.
