"Pollen rain" fell in Changsha in central China's Hunan Province last week, which experts said was not harmful to human health.
People suspected that the yellow-colored downpour brought on April 5 was industrial pollution or waste gas. Many parents did not allow their children to go outdoors for fear of being infected. After tests were conducted, the municipal environment bureau said that the yellow-colored downpour was large amounts of rape pollen.
The vegetable is the most popular plant in central China's Hubei and Hunan provinces. It is presently the flower season for rape.
