In this paper, statistical analysis to examine the links between pollution
and the types of kitchen and fuels is carried out for rural houses by first
monitoring the indoor air quality (IAQ) followed by regression analysis of
418 households in Tamil Nadu, India. Exposures to the chief cook (females,
who are mainly involved in the cooking during monitoring) are measured wit
h personal monitors. The result shows that the values of respirable particl
es (PM10) ranged from 500-2000 mug/m(3) during a two-hour cooking period fr
om burning biofuels. The range depends on the type of kitchen and fuel use.
Stationary monitors, placed two metres away from the stove, also recorded
similar concentrations. Thus, the individuals who stay inside the houses us
ing biofuels also face high concentrations even if they are not cooking. Th
ey could be senior citizens, children or adult males. Thus, there are two m
ajor findings from this analysis. Improved house designs that pay attention
to kitchen location and put up partitions should also be considered in the
intervention portfolio. Secondly, the exposure is not limited to the cooks
alone. The rest of the family in the vicinity is also exposed through a "p
assive cooking effect". (C) 2001 Elsevier Science Ltd. All rights reserved.
