Gas Stoves Emit More Harmful Nanoparticles Than Vehicle Exhaust: Study

A study by Purdue University found that cooking on gas stoves emits more nano-sized particles into the air than vehicles running on gas or diesel, potentially increasing the risk of respiratory illnesses. These tiny nanoparticles, called nanocluster aerosol, can reach deep into the respiratory system and spread to other organs. The study suggests using kitchen exhaust fans while cooking on gas stoves and highlights the need to consider nanocluster aerosol as a distinct air pollutant category. The research, conducted in a specially designed "tiny house" lab, revealed that adults and children could be breathing in 10-100 times more nanocluster aerosol from gas stove cooking indoors than from car exhaust while standing on a busy street.
