Air quality assessment at hazardous waste sites

摘要: Abstract Human health risks due to exposures an area of contamination are needed be addressed both onsite and offsite through inhalation the ambient air associated with contaminated sites. The human risk is identified volatilization factor defined in USEPA Health Manual. exposure can investigated use direct monitoring dispersion modeling. Air quality modeling especially valid for areas which sources impact not clearly defined. emission rate estimation detected compounds necessary order calculate on‐site off‐site model runs.
