Strong variations in urban allergenicity riskscapes due to poor knowledge of tree pollen allergenic potential

Abstract Exposure to allergenic tree pollen is an increasing environmental health issue in urban areas. However, reliable, well-documented, peer-reviewed data on the allergenicity of pollen from common tree species in urban environments are lacking. Using the concept of ‘riskscape’, we present and d...
