使用有机砷化合物处理的甘蔗的蔗汁和蔗渣的砷含量每一公顷(折合15亩)分别使用5.2公斤和8公斤的甲烷胂酸二钠除莠剂(63％商品)处理过的甘蔗,在7个月后逐月对其蔗汁和蔗渣的砷含量进行分析。蔗汁和蔗渣的砷含量随着时间而减低,在5个月后蔗汁中含砷的最高剂量和最低剂量分别为0.048ppm和0.040ppm,蔗渣含砷的剂量则为0.145ppm。这些数字被看作是正常限度,但认为在甘蔗收获前至少5个月是不适宜施用含砷的除莠剂。
Arsenic content of sugarcane sugarcane bagasse and bagasse treated with organic arsenic compound 5.2 kg and 8 kg of cacodylate disodium (63%) treated sugar cane per hectare (15 mu) After 7 months, the arsenic contents of its cane juice and bagasse were analyzed month by month. The arsenic content of cane juice and bagasse decreased over time, with the highest and lowest doses of arsenic in sugarcane juice at 0.048 and 0.040 ppm, respectively, and the sugarcane bagasse at 0.145 ppm after 5 months. These numbers are seen as normal limits, but it is not considered desirable to use arsenic-containing herbicides at least 5 months prior to sugarcane harvest.
