Leachates of Cr and Ni from stainless steel utensils viz., frying pans, bowls and tumblers, have been investigated, by exposing the utensils to decinormal solutions of citric, tartaric and lactic acids and to some common Indian drinks. A comparison of observed results indicate that the complexation of metal ions with organic acid anions is most vital and metal leaching is largely a function of the availability of free anions. The intake of Cr and Ni by human beings has also been calculated.
通过将不锈钢器具（即煎锅、碗和杯子）暴露于柠檬酸、酒石酸和乳酸的十分之一当量溶液以及一些常见的印度饮料中，对其中铬和镍的沥出物进行了研究。观察结果的比较表明，金属离子与有机酸阴离子的络合最为关键，金属沥出在很大程度上取决于游离阴离子的可用性。还计算了人类对铬和镍的摄入量。
