State records list the three largest parent companies. Counties carry the Census FIPS code. Dioxin-like compounds, which facilities report in grams, are converted to pounds. TRI counts reported releases by listed chemicals from covered facilities; it is not a measure of exposure or of harm.","key":"jurisdiction","count":2494,"keys":[{"key":"AK","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/AK.json","records":16},{"key":"AL","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/AL.json","records":65},{"key":"AR","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/AR.json","records":62},{"key":"AS","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/AS.json","records":1},{"key":"AZ","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/AZ.json","records":16},{"key":"CA","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/CA.json","records":48},{"key":"CO","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/CO.json","records":31},{"key":"CT","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/CT.json","records":9},{"key":"DC","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/DC.json","records":2},{"key":"DE","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/DE.json","records":4},{"key":"FL","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/FL.json","records":60},{"key":"GA","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/GA.json","records":123},{"key":"GU","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/GU.json","records":2},{"key":"HI","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/HI.json","records":5},{"key":"IA","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/IA.json","records":92},{"key":"ID","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/ID.json","records":32},{"key":"IL","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/IL.json","records":80},{"key":"IN","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/IN.json","records":86},{"key":"KS","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/KS.json","records":59},{"key":"KY","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/KY.json","records":81},{"key":"LA","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/LA.json","records":57},{"key":"MA","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/MA.json","records":14},{"key":"MD","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/MD.json","records":21},{"key":"ME","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/ME.json","records":16},{"key":"MI","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/MI.json","records":68},{"key":"MN","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/MN.json","records":70},{"key":"MO","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/MO.json","records":87},{"key":"MP","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/MP.json","records":2},{"key":"MS","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/MS.json","records":71},{"key":"MT","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/MT.json","records":25},{"key":"NC","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/NC.json","records":84},{"key":"ND","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/ND.json","records":27},{"key":"NE","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/NE.json","records":48},{"key":"NH","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/NH.json","records":11},{"key":"NJ","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/NJ.json","records":21},{"key":"NM","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/NM.json","records":16},{"key":"NV","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/NV.json","records":17},{"key":"NY","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/NY.json","records":60},{"key":"OH","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/OH.json","records":87},{"key":"OK","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/OK.json","records":58},{"key":"OR","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/OR.json","records":32},{"key":"PA","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/PA.json","records":65},{"key":"PR","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/PR.json","records":43},{"key":"RI","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/RI.json","records":6},{"key":"SC","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/SC.json","records":46},{"key":"SD","url":"https://probativegrowth.com/data/v1/toxic-releases/jurisdictions/SD.json","records":29},{"key":"TN","url":"https://probative
