“An assessment of chemical and biological significance of arsenical compounds in the Maurice River Drainage Basin (N.J). Part III. Transformations in aerobic and anaerobic conditions”

Abstract

A quiescent reservoir system revealed the effects of temperature (20°C. & 30°C), oxygen levels (aerobic & anaerobic) on the arsenic partitioning and Interconversion in organic and sandy lake sediments. Temperature had little or no effect on the specie partitioning. In aerobic reservoirs (sandy & organic), the As(V) levels increased, especially in the organic sediment. In the anaerobic reservoir, the organic sediment maintained its level of As(III). The sandy sediment has a predominance of As(V) suggesting something other than the level of oxygen is a significant controlling factor.
