Sources of Indoor Pollution in Schools

Indoor pollutants can originate within a school building or be drawn in from outdoors. Air contaminants can consist of particles (including dust, fibers, pollens, mould spores, bacteria and viruses) and various gases or vapours.

Outdoor sources can include: natural pollens and moulds; exhaust emissions from cars, trucks, homes, industries, and the school building itself; odours from garbage bins; pesticides from lawn and garden care; radon or volatiles in soil gases.

Indoor sources related to equipment include: microbiological growth in drip pans, ductwork, coils and humidifiers; volatile organic compounds and ozone from office equipment; shops and labs.

Indoor sources related to building components and furnishings include: soiled or water-damaged materials; sewer gas from dry water traps; high-emission building materials (e.g. particleboard, paint, caulking, adhesives); new furniture, wall surfaces or flooring;

Other indoor sources include: cleaning compounds and procedures; special activity areas such as science labs, vocational arts, copying and printing, food preparation and smoking lounges; garbage odours; pesticides; infected individuals; dry-erase markers and pens; insects and other pests; personal care products including perfume and aftershave.
