Particulate matters detrimental to health

Tehran, July 2, IRNA -- Particulate matters adversely affect human health, said head of the Health Ministry’s Office for Occupational and Environmental Health.

Kazem Naddafi added that particulate matters have different sizes, noting larger particulate matter is filtered by nose and throats, but smaller ones can penetrate deep into the lungs.

He said large particulate matters, accounting for a major part of particle pollution suspended in air, do not pose a major threat to human health, reiterating that they can create problems for patients with breathing disorders.

“New born babies, children and teenagers, elderly, those suffering from breathing diseases including asthma and bronchitis and patients with cardiovascular diseases are more vulnerable to adverse health effects of small particulate matters.”

Naddafi said the exposure of such people to particulate matters will create more problems for them and reduce their lifespan.

Referring to the steps to avoid the negative impacts of this natural phenomenon, he said on days when particulate matter is high, people should limit their outdoor activities, keep the doors and widows tightly closed and stay in air-conditioned rooms.

“Asthma patients and those with breathing problems should follow up their treatment in such circumstance and refer to physicians if the problems persist,” he said.

He urged the people to keep food products and drinking water in air-tight containers.

Particulate matters are tiny pieces of solid or liquid matter associated with the Earth's atmosphere. Sources of particulate matter can be manmade or natural.
