Volcanic ash fear for lung sufferers

After scientists from Sheffield said they had detected particles of ash in the air around the city, the World Health Organisation (WHO) said the situation has potential health consequences for tens of thousands of people.

Spokesman Dan Epstein said: "From what we know at the moment, the majority of cloud ash is 7km (23,000ft) to 10km (32,800ft) high in the atmosphere. If it does reach the ground, it may have health effects.

"People with existing respiratory conditions such as asthma, emphysema and bronchitis should avoid breathing in these particles. They should have their inhalers and other medication with them."

A spokesman for the Health Protection Agency added: "It is important to stress that the concentration of particles which may reach ground level is likely to be low and should not cause serious harm.

"If people are outside this evening and notice symptoms such as itchy or irritated eyes, runny nose, sore throat or dry cough, or if they notice a dusty haze in the air or can smell sulphur, rotten eggs or a strong acidic smell, they may wish to limit their activities outdoors or return indoors.

"Those with existing respiratory conditions such as chronic bronchitis, emphysema and asthma may notice these effects more than others, and should ensure they have any inhalers or other medications with them. Any such health effects are likely to be short-term."

The advice was echoed by Professor Malcolm Green, from the British Lung Foundation, who said: "We would advise people living with a lung condition in affected areas to carry their medication as a precaution as they may experience a short-term worsening of symptoms."

The National Pollen and Aerobiology Research Unit, based at the University of Worcester, has now switched its activities from studying pollen levels to measuring the volcanic ash over Britain.
