Finding F-0986

“Indoor air concentrations associated with biomass smoke were six-fold greater in rural vs. urban households.”

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)
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: the multiple is written as a word, so no figure is carried

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.
