(Environmental Health Perspectives) A study in California homes found that indoor natural gas cooking burners (NGCBs) can emit high levels of pollutants, leading to health risks for residents. The study used a mass-balance model to estimate pollutant concentrations and occupant exposures, finding that without using venting range hoods, 62% of residents were exposed to NO2 levels exceeding health standards and 53% to HCHO levels exceeding standards.
