説明
The metabolic fate of fungicide MAFA [ammonium iron methanearsonate; (CH3AsO3)m Fen·NH4] was studied in three types of siols under moist conditions. The monomethylarsenic (MM-As) moiety of MAFA degraded with a half-life of 22-32 days. Inorganic-arsenic (Inorg-As) was interpreted as a terminal product due to its uninterrupted increase in amount with time. There was a remarkable difference in the residual amount of dimethyl-arsenic (DM-As) products depending on the soil type. Degradation rates of dimethylarsinic acid and trimethylarsine oxide were also highly dependent on the soil type. The rate and the direction of MAFA transformation in a soil did not significantly change when its microbial population was replaced with other's. The effects of soil moisture and exogenous glucose on MAFA or DSMA (disodium methanearsonate) transformation were examined. Volatile-As products were observed in glucose-amended soils under moist and flooded conditions, and trimethylarsenic (TM-As) was found to be their principal component.
