Feb. 2003 Emissions from charbroiling and grilling of chicken and beef. CHARBROILING PRODUCES LARGE QUANTITIES OF PARTICULATES
Meat cooking is a major source of air pollution, especially if meat is overcooked, charbroiled or cooked on a wood stove . It is estimated that meat cooking produces 21% of the particulates smaller than 2.5 microns (PM2.5) in Los Angeles (Aerosol Science and Technology 1991;14:138-152). A Nevada study found that charbroiling chicken and beef produced about 3 to 5 times more particulates than grilling.

[Ed. when the solid food becomes fuel - (when it is charred, burned) it also becomes fine particulate.]

Jan. 2003 Effect of indoor air pollution from biomass combustion on prevalence of asthma in elderly. BIOMASS COOKING FUELS AND MORE ASTHMA
Biomass fuels such as wood, peat, dung and straw are often used in 3rd world countries to cook food. These biomass fuels produce a lot more air pollution than burning cleaner fuels like kerosene, natural gas, propane or electricity. A study of 38,595 Indian adults over age 60 found that those who used biomass cooking fuel had 1.59 times the incidence of asthma as compared to adults using cleaner fuel (95% confidence limit of 1.30-1.94).
