砷剂是常见的刺激物,会引起接触组织如皮肤,胃肠道以及呼吸道的炎性反应。砷剂还具有接触性变应原的作用,以致较低的剂量都会使以前敏感的人出现反应。注意在足够量时,砷会通过在皮肤、肝、中枢神经系统、周围神经、动脉内皮、心肌以及骨髓中的积蓄而产生有害作用。曾有报道慢性过量的砷吸收会使皮肤癌,肺癌,乳腺癌以及淋巴腺瘤的危险度增加。 作者报道了三年间职业卫生门诊部诊断的职业性
Arsenic is a common irritant that causes inflammatory reactions in contact with tissues such as the skin, the gastrointestinal tract, and the respiratory tract. Arsenic also has the effect of a contact allergen, so that lower doses can cause reactions in previously sensitive individuals. Note that arsenic can have a deleterious effect by accumulating in the skin, liver, central nervous system, peripheral nerves, arterial endothelium, myocardium, and bone marrow in sufficient quantities. It has been reported that chronic excess of arsenic uptake increases the risk of skin cancer, lung cancer, breast cancer, and lymphatic adenoma.
