There was diurnal variation with values decreasing after evening handovers to an overnight average minimum of 51 d BA at 4 AM.

This extensive scientific assessment identifies which energy systems can be considered clean for health in the home, and specifies the levels of emissions that pose health risks.

The guidelines also include recommendations against the use of unprocessed coal as a household fuel, and against the use of kerosene as a household fuel, in the light of health and safety risks.
