Pollen allergy is a very serious seasonal respiratory disease. However, there has been a lack of understanding how pollen allergens enter the body and act on cells. This study focused on the release, transport and characteristic of Pla a3 allergen of the Platanus acerifolia pollen.

Site environmental assessment to an old paint factory in China.

High ethyl-benzene and total petroleum hydrocarbons (TPHs) were found in the soil samples and groundwater samples during a site environmental assessment for an old paint factory in the city Changchun, Jilin province of China. The target old paint plant had been in operation for near 30 years by manufacturing resin and house paint. Driving force for this study was to identify potential environmental contamination existing in this paint factory which is located next to a new resident area under construction.
