About Pollen in Chongqing

Chongqing’s spring (February-May) is dominated by Pine and Cypress pollen; Masson Pine (Pinus massoniana) dense on Nanshan Mountain and Geyue Mountain; Chinese Weeping Cypress (Cupressus funebris) widespread in Eling Park. Privet (Ligustrum) contributes significantly from urban residential areas. Summer (June-August) sees high Grass (Poaceae) pollen levels, originating from the Yangtze and Jialing riverbanks.

Mountainous terrain and dense fog trap allergens, leading to high local concentrations. Autumn and winter see elevated Mould (Alternaria, Aspergillus) spore counts, from damp riverfronts and moist soils in Jinyun Mountain forests.
