AIRBORNE PARTICLE EMISSIONS FROM 2- AND 4-STROKE OUTBOARD MARINE ENGINES: POLYCYCLIC AROMATIC HYDROCARBON AND BIOASSAY ANALYSES

Outboard and personal watercraft (marine) engines are reported to be significant sources of air pollutants accounting for approximately 141 tons of reactive hydrocarbons emitted per day in California alone, for example. The emissions from 2-stroke marine engines have traditionally been investigated for the regulated pollutants hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx). However, very few studies have been published on airborne particulate matter (PM) and PM-associated unregulated toxic air pollutants emitted during the normal operation of the engine in the water. In the current investigation, the authors report on the airborne PM emissions from two types of 2-stroke marine engines (carbureted and direct fuel-injected models) and a 4-stroke engine (carbureted) that were operated in water at a special emissions testing facility.
