Structure

Source: Biomass fuel
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Intervention: Improved cookstoves
Setting: kitchen, IN
Study design: field testing of five alternative cookstoves against the traditional cookstove in a real-world test kitchen in rural western India: PM2.5 and carbon monoxide measured over one-hour cooking tests, twelve trials per stove (class 3)
Effect: difference 61
Averaging time: 1 h test
Caveat: PM2.5 was significantly lower for all five alternative stoves
