An empirical model for attributing sources of particulate matter

Perry K. Davy & W. B. Trompetter
Airborne particulate matter (PM) pollution is well-known to have significant adverse effects on human health. It also has a range of environmental effects, including local reductions in visibility, effects on the radiative balance and deposition of contaminated material onto land and waterways. Because of these effects, PM concentrations are routinely monitored in numerous countries and managed according to local legislation. In New Zealand, the National Environmental Standard (NES) for PM sets a 24-hour average limit...
