Statistical Methods to Apportion Heavy Metalsited to the task. This paper examines the limitations of standard statistical methods in general and regression and factor analysis in particular. New statistical methods must be developed that have a sound physical basis and can overcome or minimize the problems of working with atmospheric data. Ex

Dry Deposition of Trace Elementscriptions of physical processes and mathematical relations. Semi-empirical models are discussed and compared. Dry deposition field sampling programs, representing a variety of locations and measurement techniques, are described. The results show wide variations in dry deposition velocities, with cru

Behavior of Cd, Mn, and Pb in Forest-Canopy Throughfallranch Watershed in the southeastern United States over a 2-year period. The interaction of rain with the canopy resulted in a measurable increase in the concentrations of all metals in throughfall, most significantly in the concentration of Mn (which increased by a factor of 160 compared to a factor

Atmospheric Transformations of Trace Metals: Evidence for Aerosol Sulfur Association with Metals froadsorption of pollution or natural sulfur, nitrogen, or other acid precursors. The resulting solubilized trace metals, upon deposition to the surface, may be more biologically available than the metals in insoluble mineral form. As evidence for the process, the variability in time sequence aerosol c
