The chimica oxygen demand (COD) for Formaldehyde, reaction products with ethylenediamine was determined to be 0.71 mg O2 per mg substance. The maximum percent biodegradation for Formaldehyde, reaction products with ethylenediamine of 70% was observed on days 20 and 28. The sodium acetate 2 mg/L reference control achieved greater than 60% biodegradation within the 28 day test period i.e. maxium biodegradation of 103% was observed on day 13. Dissolved oxygen depletion in the seawater controls remained within the test guideline of 30%; on day 28 a maximum dissolved oxygen depletion of 6.8% occurred (control oxygen levels had decreased from 7.4 mg/L on day 0, to 6.9 mg/L on day 28).
Examination of control seawater and seawater containing 2 mg/L ofFormaldehyde, reaction products with ethylenediaminefor possible nitrite (NO2 and NO3) formation was conducted on days 27 and 28. No evidence of nitrification was evident; nitrite and nitrate levels for exposure bottles were at or below those of the seawater control at these times.
