对砷中毒地区及对照区的227人进行的研究发现，高砷饮水地区人群血清酪氨酸平均水平为14.20μg/L，与对照区12.20μg/L相比差异有极显著性意义（P＜0.01）。还发现酪氨酸含量与砷中毒的一些症状如色素沉着、周围神经炎等有相关性。血清酪氨酸含量与发砷水平之间的等级相关系数为0.926。结果表明砷中毒可能导致血清酪氨酸含量升高并由此引起一些相应症状。
Arsenic poisoning areas and control areas 227 people study found that high arsenic drinking water area of the population average serum tyrosine 14.20μg / L, compared with the control area 12.20μg / L was significantly different (P < 0.01). Also found that tyrosine content and arsenic poisoning symptoms such as pigmentation, peripheral neuritis and other related. The rank correlation coefficient between serum tyrosine levels and arsenic levels was 0.926. The results show that arsenic poisoning may lead to elevated serum levels of tyrosine and thus cause some of the symptoms.
