acceptable daily intake The measurement of the amount of any chemical substance that can be safely consumed by a human being in a day. Calculations are usually based on the maximum level of a substance that can be fed to animals without producing any harmful effects. This is divided by a "safety factor" to allow for the differences between animals and humans and to take account of the variation in human diets (人一天内可安全摄入的化学物质计量。计算结果通常以动物可摄入且不产生有害影响的物质最大量为基础。依据"安全因素"进行划分，以兼顾人类和动物的不同以及不同人的饮食差异。) |
