Indoor Air Pollution Formaldehyde is an indoor air pollutant formerly found inplywood, foam insulation, and carpeting. When concentrations in the air reach33 micrograms per cubic foot , eye irritation can occur. One square foot of newplywood could emit 140 mg per hr. (Source: A. Hines, Indoor Air Quality & Control.)
(a) A room has 100 ft2 of new plywood flooring. Find a linear equation F that computesthe amount of formaldehyde, in micrograms, emitted in x hours.
(b) The room contains 800 ft3 of air and has no ventilation. Determine how long it
would take for concentrations to reach 33 . (Round to the nearest tenth.)
