代谢

镉可以通过口服、吸入和皮肤途径被吸收。镉最初与金属硫蛋白和清蛋白结合，并主要运输到肾脏和肝脏。当镉的浓度超过了可用金属硫蛋白的浓度时，就会观察到毒性效应，而且已经证明镉-金属硫蛋白复合物可能具有损害性。镉不为人所知的是进行任何直接的代谢转化，并以原形排出，主要在尿液中。

Cadmium is absorbed from oral, inhalation, and dermal routes. Cadmium initially binds to metallothionein and albumin and is transported mainly to the kidney and liver. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Cadmium is not known to undergo any direct metabolic conversion and is excreted unchanged, mainly in the urine. (L6)

• 毒性总结

镉最初与金属硫蛋白结合，并运输到肾脏。当镉的浓度超过了可用金属硫蛋白的水平时，就会观察到毒性效应，而且已经证实镉-金属硫蛋白复合物可能具有损害性。肾脏中镉的积累导致重要低分子量和高分子量蛋白的排泄增加。镉是锌的高亲和力类似物，能够干扰其生物过程。它还与雌激素受体结合并激活它，可能刺激某些类型癌细胞的生长并引起其他雌激素效应，如生殖功能障碍。镉通过激活丝裂原活化蛋白激酶导致细胞凋亡。(L8, A18, A19, A28)

Cadmium initially binds to metallothionein and is transported to the kidney. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Accumulation of cadmium in the kidney results in increased excretion of vital low and high weight molecular proteins. Cadmium is a high affinity zinc analog and can interfere in its biological processes. It also binds to and activates the estrogen receptor, likely stimulating the growth of certain types of cancer cells and causing other estrogenic effects, such as reproductive dysfunction. Cadmium causes cell apoptosis by activating mitogen-activated protein kinases. (L8, A18, A19, A28)

毒理性

• 健康影响

长期暴露于镉烟雾可能会导致化学性肺炎、肺水肿以及诸如支气管炎和肺气肿等肺部疾病。镉还会在肾脏中积累，造成永久性损害。还会出现骨密度流失。

Chronic exposure to cadmium fumes can cause chemical pneumonitis, pulmonary edema, and lung diseases such as bronchitis and emphysema. Cadmium also accumulates in the kidneys, causing permanent damage. Loss of bone density also occurs. (L6)

毒理性

• 症状

急性吸入镉烟尘会导致金属烟雾热，其特点是寒战、发热、头痛、乏力、鼻和喉咙干燥、胸痛和咳嗽。摄入镉会引起呕吐和腹泻。

Acute inhalation of cadmium fumes results in metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Ingestion of cadmium causes vomiting and diarrhea. (L6)
