Studies were conducted in six artificial stream channels to determine the fate of NTA (nitrilotriacetic acid, trisodium salt) added with and without sodium phosphate to these systems. In the two hour period required for a given water mass to traverse the channels, there was no appreciable amount of NTA or phosphate, even after a one month period of continuous input. Visible biological differences were noted between the various treatments. These differences may have been a result of pH alteration caused by the addition of the trisodium phosphate and NTA. In anticipation of a long term program involving the fate of mercury and possible mercury-NTA interactions, several modifications were incorporated into the artificial stream system. Based on the results of laboratory studies, a mercury removal system utilizing shredded rubber tires as obtained from commercial tire recapping firms, was constructed. Laboratory studies indicated that NTA did not influence the uptake of mercuric ion by the rubber. The presence of NTA did alter the uptake pattern and final concentration by mosquitofish, Gambusia affinis.
