remediation of indoor air pollution problems involve modifications of box model parameters that result in concentration reductions. for example, reduction of the source rate directly reduces concentration. what do ventilation and the use of air cleaners have in common with respect to the box model?

Respuesta :

They both reduce the residence time of pollutants ventilation and the use of air cleaners have in common with respect to the box model.

Any chemical or energy that is put into the environment and has unintended effects or negatively impacts the use of a resource is considered a pollutant or new entity. These can be created either naturally (such as minerals or extracted chemicals like oil) or artificially (due to human activity) (i.e. manufactured materials or byproducts from biodegradation). When pollutants are present at levels that have a major negative influence on the environment or public health, they become pollutants.

By altering the rate of animal or plant species' growth, or by affecting people's amenities, comfort, health, or property values, a pollution may cause long-term or short-term damage. Because they biodegrade, some contaminants won't last very long in the environment.
