Abstract

Two sizes of excised microcosms (15 and 30 cm in diameter) and 30 cm diameter homogenized microcosms were compared with field plots to assess the transport of As in a grassland ecosystem. The purpose of the experiment was to determine the suitability of using microcosms for measuring the transport of toxic substances through grassland ecosystem components (soil, grass, and soil water). Arsenic was applied to each set of microcosms and the field plots, at rates of 0, 0.5, and 5.0 mg cm−2. Results show that As was highly assimilated by grass, with the greatest concentration being 720 ppm. The microcosms were found to represent the field plots in terms of As transport, and offer several advantages over field testing of toxic substances.
