An atmospheric selenium budget for the region 30° N to 90° N

Ross (1985) estimated fluxes of 36-100 × 10^8 g Se/year for wet deposition and 5.5-26 × 10^8 g Se/year for dry deposition in the region between 30°N and 90°N.

“Ross (1985) [90] estimated fluxes of 36–100 × 108 g Se year−1 and 5.5–26 × 108 g Se year−1, for wet and dry deposition, respectively.”

Global atmospheric selenium budgets indicate atmospheric selenium input fluxes between 15.5 and 15.7 × 10^9 g/year, of which about 60% are natural and 40% anthropogenic emissions, although the natural contribution was smaller (25%) in the northern hemisphere due to anthropogenic emissions.

“Global atmospheric Se budgets [85,86,87,88,89] indicated that atmospheric Se input fluxes are between 15.5 and 15.7 × 109 g·year−1, of which ~60 and 40% are natural and anthropogenic emissions, respectively [40], although the contribution of natural emissions was found to be smaller (i.e., 25%) in the northern hemisphere due to anthropogenic emissions [90].”
