health

There is an increasing concern at the possible health effects of fine suspended particulate (aerosol) upon human health, particularly in the urban environment. Aerosol infiltrating indoors may arise from transport, power generation and natural sources. Aerosol also arises from indoor sources, through cooking processes for example, and from animal dander. In zones within a building, within which the air is reasonably well-mixed, the levels of aerosol will depend upon the ventilation rate and the rate of deposition on indoor surfaces.

This guide combines two complementary disciplines, engineering and biology. It will provide people involved from the design to the evaluation. to the operational phase of ventilation systems with not only a better understanding of the relations hi p between operation and the appearance of conditions favor able to the development of microorganisms , but also the means for controlling their growth.
