Air Toxics – Cancer Risk by Census Tract

| 0

Layer displays the modeled cancer risk associated with air toxics exposure. Figures represents the likelihood of hazardous exposure per 1 million population.

Air Toxics – Non-Cancer Risk by Census Tract

| 0

Layer displays the modeled non-cancer risk associated with air toxics exposure. A hazard index (HI) of 1 or lower means air toxics are unlikely to cause adverse noncancer health effects over a lifetime of exposure.
