Finding F-0987

“Having a homemade chimney did not reduce environmental exposures significantly.”

A cross-sectional study of determinants of indoor environmental exposures in households with and without chronic exposure to biomass fuel smoke (2014). Environmental health : a global access science source. Page 1. CKB 6892

Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Intervention: Ventilation
Setting: home, PE
Study design: cross-sectional study of determinants of indoor exposures in the department of Puno, Peru: households selected from a census of urban and rural communities by cooking fuel and chimney, with 24-hour indoor PM and carbon monoxide and with exhaled carbon monoxide and exhaled carboxyhaemoglobin measured in the cooks (class 4)
Caveat: a null result stated without a number; the chimneys were self-built rather than installed to a design

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
