presumably biological processes. Formaldehyde in aqueous effluent is degraded by activated sludge and sewage in 4872 hours. In a die-away test, using water from a stagnant lake, degradation was complete in 30 hours under aerobic conditions and 48 hours under anaerobic conditions. Bhattacharya and Parkin used anaerobic chemostats to study fate and kinetic effects of sludge and continuous additions of formaldehyde to acetate and propionate enrichment systems. The high reduction of formaldehyde with continuous addition is indicative of biodegradation, since the combination of volatilization, adsorption, and chemical transformation should account for less than 25% of the removal. Up to 80% of the formaldehyde was removed, with biodegradation accounting for 5560%. Sediment and Soil The fate of formaldehyde in soil has not been determined HEALTH EFFECTS Acute toxicity
