A survey of the distribution of ragweed in Qingdao district was carried out. Ambrosia-artemisifolia has been found to be widespread in many areas. The results of the survey showed that ragweed pollen was the chief allergen of the district and that it was 18%-21.3% of total air-borne pollen in a year. Skin tests with Ambrosia allergen extracts showed a positive rate of 67.7% in 624 cases of pollinosis. Ragweed pollens have become the major allergic pollen, causing important pathogenesis with pollinosis in the district. Preventive measures must be taken to eradicate ragweed. Otherwise it certainly will spread all over China.
