# curated.env_tri_release
EPA Toxics Release Inventory 2014-2024, pounds released per facility x chemical x year (37,234 rows; category: Environment; geometry column `geom` (Point, EPSG:4326))
Notes: Sum total_releases (on-site + off-site, pounds) or fugitive_air + stack_air for air emissions. carcinogen = 'YES' flags OSHA carcinogens. Filter unit = 'Pounds' before summing (dioxins are grams). Counties are upper case ('HARRIS').
