  1. The units of the above indicators: UCd (μg/g cr), UNAG (U/g cr), Uβ2-MG (μg/g cr). Chi-squared linear trend test, p < 0.01. 5 μg / g cr is the criterion for determining abnormality of UCd. 17 U/g cr is the criterion for determining abnormality of UNAG. 1000 μg / g cr is the criterion for determining abnormality of Uβ2-MG
