Source of respirable particles indoor includes Cigarettes, Wood Stoves, Fireplaces, Aerosol Sprays and House Dust Dust particles of any substances that are less than or equal to 10 micrometres diameter. Particles in this size range make up a large proportion of dust that can be drawn deep into the lungs. Larger particles tend to be trapped in the nose, mouth or throat. Size is not an absolute criterion as thin flakes and fibres longer than 10 micrometres may be part of a PM10 sample because of their aerodynamic properties.

Effect of respirable Particles on health includes;

• toxic effects by absorption of the dust into the blood (e.g. lead, cadmium,
• allergic or hypersensitivity effects (e.g. some woods, flour grains, chemicals);
• bacterial and fungal infections (from live organisms);
• fibrosis (e.g. asbestos, quartz);
• cancer (e.g. asbestos, chromates);
• irritation of mucous membranes (e.g. acid and alkalis); and
• long-term deleterious effects on lung function causing marginally increased
death rates and sickness in sensitive people.

The factors that influence the health effects are:
• the composition of the dust and its health effects;
• the concentration of the dust;
• the size of the dust (smaller particles tend to have more severe effects
because they may be inhaled more deeply into the lungs); and
• the duration of exposure (possibly in years).
