Determinations of the arsenic contents in subjects, aged 10-11 years, from an arsenic-exposed region yielded the following arithmetic means: hair, 5.5 p.p.m. (S.D. = +/- 4.2); urine, 0.011 p.p.m. (S.D. = +/- 0.010). In children from a non-exposed region the authors found; hair, 0.5 p.p.m. (S.D. = +/- 0.4); urine, 0.004 p.p.m. (S.D. = +/- 0.005). The average arsenic concentrations in the exposed region were 19 mg/m2-30 d (sedimentation dust) and 0.9 microgram/m3 (aerosol); the corresponding values for the control region were 0.029 mg/m2-30 d and 0.0 microgram/m3, respectively. The two groups of subjects had general clinical examinations. There was a significant difference between the two groups in total morbidity, whereas the morbidity structure was similar. This result cannot be brought in causal relation to the differences in arsenic contents; it is possible that other influences play a rôle in the region under investigation.
对来自砷暴露地区的10至11岁受试者的砷含量测定得出以下算术平均值：头发，5.5 ppm（标准差=±4.2）；尿液，0.011 ppm（标准差=±0.010）。作者在来自非暴露地区的儿童中发现：头发，0.5 ppm（标准差=±0.4）；尿液，0.004 ppm（标准差=±0.005）。暴露地区的平均砷浓度为19 mg/m² - 30天（沉降灰尘）和0.9微克/m³（气溶胶）；对照地区的相应值分别为0.029 mg/m² - 30天和0.0微克/m³。对两组受试者进行了全面的临床检查。两组在总发病率上存在显著差异，而发病结构相似。这一结果无法与砷含量的差异建立因果关系；在被调查地区可能有其他影响因素在起作用。
