Arsenic at a concentration of 10 to 70 parts per million has been detected in several common presoaks and household detergents. Arsenic values of 2 to 8 parts per billion have been measured in the Kansas River. These concentrations are close to the amount (10 parts per billion) recommended by the United States Public Health Service as a drinking-water standard.
在几种常见的预浸泡液和家用洗涤剂中，已检测到浓度为百万分之10至70的砷。在堪萨斯河中测得的砷含量为十亿分之2至8。这些浓度接近美国公共卫生服务部建议作为饮用水标准的量（十亿分之10）。
