Passive removal of secondary pollutants due to squalene oxidation in a primary school: a mathematic analysis


This study investigates the performance of the passive reduction of ozone and secondary pollutants due to squalene oxidation in a Texian primary school.  The pollutant levels are compared using a mass balance model in the classroom when different type of gypsum board is used as a passive pollutant removal system. The effects of different parameters-such as air exchange rate, percentage of skin flake coverage on the floor and student numbers-are also assessed. The results show that reactive gypsum boards offer an energy-saving opportunity to remove indoor pollutants. Gypsum boards can reduce pollutants at a level equivalent to that offered by an increase in ventilation rate.  The use of wall paper-faced gypsum board leads to a 15.1% and 19.1% decrease in ozone and its byproducts, respectively.
