接触剂量又称染毒剂量（administrated dose）或外剂量（external dose）。动物毒理实验时指染毒量或给药量，人体接触外来化合物时指接触量，常以每单位体重毫克数（mg/kg）或每单位体表面积毫克数（mg/m2）表示其剂量。接触环境污染物时，根据大气、食品、水等环境介质中的浓度乘以进入机体的介质总量，来估算剂量。对外来化合物的接触剂量、接触时间及频数的定量估算，是研究剂量-反应关系的基础。
目的：探讨五金工业噪声性耳聋患病率与噪声接触剂量之间的关系。
Objective: To assess the dose response relationship between the prevalence rate of noise deafness and the noise exposure.
目的：探讨镉接触剂量与肾损害指标之间的剂量-反应关系，寻找较敏感和稳定的镉损害的早期诊断指标。
