Abstract
Phosphoais fractions in 15 samples of rain, rain plus dust, or snow were analyzed to shed light on the role of aeolian P in the nutrient budgets of lakes. Total Plevels varied (6.6 to 122.4 μg P/ℓ) but were generally high (mean = 47.0 μg P/ℓ; 76% of this was dissolved. Biologically available orthophosphate comprised an average of 38% of the total. Neither soluble reactive P nor small molecular weight P eluting with 32P-PO4 in gel filtration were consistently adequate estimates of orthophosphate concentrations.
