Abstract

Dry deposition flux and airborne concentration measurements were made over southwestern Lake Michigan in July of 1994 to determine atmospheric inputs of contaminants to the lake. Results show that despite relatively low concentrations of large (>4 μm) particles, these particle account for greater than 75% of the dry deposition mass flux. Dry deposition velocities for particulates were found to range from 0.0042 cm/s for 0.25 μm particles to 2.1 cm/s for 32 μm particles. The effects of nearby urban and industrial areas as sources of pollutants to the lake are also shown.
