THE RISE in popularity of diesel-powered cars could have a serious impact on hay fever sufferers during the summer months.Allergy experts have warned that urban sufferers are at increased risk of experiencing hay fever symptoms, because of the rise in the amount of diesel particles in the atmosphere.
The beginning of June is traditionally the worst time of the year for sufferers when pollen counts are highest, especially in the countryside.
However, pollen also attaches itself to diesel particles emitted through exhaust pipes, allowing it to travel into respiratory systems.
Diesel cars now make up approximately 20 per cent of all new car sales in the Republic, and the level has been rising steadily over the past number of years.
This number is expected to jump after new rules on VRT and car tax are introduced in July which will be based on CO2 emissions and favour diesel-powered models.
Dr Brendan Fitzpatrick, a Dublin-based doctor with a special interest in allergies, said pollen levels peak at this time of the year and remain high until mid-July. "Certainly there is a feeling that a small amount of pollen can cause more symptoms of hay fever in the city because of the combined effect with diesel fumes and other pollution," he told The Irish Times.
He said between 7am and 11am and between 4pm and 8pm were times with the highest level of pollen in the air.
He added that hay fever sufferers should avoid being outside at these times, wear wrap-around sunglasses and apply Vaseline around the nostrils in an effort to minimise symptoms.
Motorists should keep windows shut to reduce the amount of pollen entering the car.
