Both two and four stroke gasoline marine engines were subjected to laboratory testing in order to evaluate both atmospheric and aqueous emissions impact. Experimental systems and procedures that provided for sampling of dry exhaust gases and aqueous samples of exhaust contaminated freshwater and saltwater were developed. Gaseous emissions results for the inboard engine did not provide adequate evidence of a loss of exhaust constituents to the aqueous phase, but alcohols and aldehydes were detected in the post-scrubbling engine cooling water for both engines. In addition, the amounts of formaldehyde and acetaldehyde present in the exhaust system were markedly reduced when exhaust scrubbing was employed.
