- Increasing concentrations of aluminum phosphide (AlP) in waste fumigants and residues pose a serious threat to human health. This study focused on the effectiveness of the widely used simple immersion treatment for waste fumigants from shipments, which usually have a higher concentration of residual AlP. A field survey of an operational process was conducted followed by a quantitative analysis of the immersion treatment's hydrolytic effect on AlP. Further investigation on the safety of waste fumigants after the immersion treatment was conducted. It was found that the AlP concentration in the waste fumigant varied significantly with the sampling date, ranging from 12.93 +/- 0.67 wt. % to 29.50 +/- 1.18 wt. %. Simple immersion treatment could reduce the concentration of residual AlP in waste fumigants but the hydrolytic effect varied largely ranging from 19.5% to 31.9%. The concentration of residual AlP remained high (9.1-20.1 wt. %) after the immersion treatment. About 3.2-15.2 wt. % of AlP remained in the samples, following an additional 40 days of natural air-drying when phosphine gas release was not detected. The study indicates that conventional simple immersion treatment cannot ensure the complete hydrolysis of AlP from waste fumigants of shipments.
