Allergy season peak comes with flying hairs

PEOPLE with respiratory diseases or allergies should be aware of the fine particles from poplar trees and plane trees as the seeds' bristly hairs and pollens are now out in force.

The local greenery authority said such flying hairs will continue for another week or two and that allergic people should avoid these trees or wear a mask while going out.

Wu Zhixing, a local plant expert, said most trees causing the recent flying hairs are plane trees, the major shade street trees in the city.

Their seed balls split in April and May, causing flying hair. The bureau regularly trims the branches to reduce seeds. But they are not trimmed so frequently on some smaller roads or those with high traffic.

Doctors from local hospitals said it is now the peak season for respiratory tract infection and allergies, as such patients have risen by 10 to 20 percent in outpatient clinics recently.
