Small Particulates and You


The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter pose the greatest problems, they can penetrate deep into the lungs, some may even enter the blood stream.


Smaller particulates less than 2.5 micrometers in diameter are even more deadly, as well as the above they have also been linked to stroke and blood clots. A recent study showed those exposed to fine particulates had a 70% increase in risk of dying from blood clots.

Exposure to such particles can effect your blood stream, lungs and heart. Particle pollution -especially fine particles-contain microscopic solids or liquid droplets, that are so small they get deep into the lungs and cause serious health problems. Numerous scientific studies carried out by the US EPA have linked particle pollution exposure to a variety of problems including, increased respiratory symptoms, irritation of the air-ways, difficulty in breathing; decreased lung function; aggravated asthma; development of chronic bronchitis; irregular heartbeat and premature death in people with heat or lung disease.


A study by the WA government DOH and DOE showed increased hospitalisation and morbitity in the young and elderly caused by particulate pollution.


So who shares our concerns, everything should be being done to keep workers and communities safe from pollution. Why have industries got licenses? We were under the misapprehension it was to stop the emission we are seing all to often.


Todays Kwinana Industry extraordinary emissions include:

Tiwest: Believed to be a white plume of Ticl4 from their emergency stack.

HiSmelt : Rustybrown & white.

CSBP: White cloud of ammonium nitate/ammonium chloride - it's not the time of year to snow.

Verve: Plume of grey particulates.
