提起化學這兩個字，大家應該會覺得那是在初高中課本里出現過的名詞，曾經我們學化學的時候，也了解過一些化學物質對人們生活的影響，既有好的影響也有不好的影響。那么關于氧化銅大家又有多少了解呢？通俗來說，銅這種金屬物質暴露在空氣中氧化后就會形成氧化銅。氧化銅見得(de)最多的(de)(de)時候(hou)是在工業中(zhong)，那么生活中(zhong)氧化銅(tong)對人體的(de)(de)傷害(hai)有哪(na)些呢？我(wo)們(men)一起來了解(jie)一下。
銅(tong)(tong)(tong)(tong)在(zai)(zai)人(ren)體(ti)(ti)中(zhong)屬(shu)于微量元(yuan)素,食用(yong)的(de)(de)(de)(de)氧(yang)(yang)化(hua)銅(tong)(tong)(tong)(tong)在(zai)(zai)胃(wei)里與胃(wei)酸(suan)反應生成CuCl2,就會被人(ren)體(ti)(ti)吸收(shou),Cu2+一(yi)旦進入(ru)人(ren)體(ti)(ti)血(xue)(xue)(xue)液(ye)超標的(de)(de)(de)(de)話(hua)就會造成重金屬(shu)元(yuan)素中(zhong)毒,主(zhu)要(yao)是可(ke)以(yi)引(yin)起(qi)(qi)體(ti)(ti)內的(de)(de)(de)(de)蛋(dan)(dan)(dan)白(bai)(bai)質(zhi)變性。然而(er)銅(tong)(tong)(tong)(tong)的(de)(de)(de)(de)另(ling)一(yi)毒理表現(xian)是損傷(shang)紅(hong)(hong)(hong)細胞引(yin)起(qi)(qi)溶血(xue)(xue)(xue)和(he)(he)(he)貧血(xue)(xue)(xue)。通(tong)常(chang)氧(yang)(yang)化(hua)銅(tong)(tong)(tong)(tong)進入(ru)體(ti)(ti)內后主(zhu)要(yao)在(zai)(zai)肝臟(zang)中(zhong)累(lei)積,一(yi)旦超過肝臟(zang)的(de)(de)(de)(de)處理水(shui)平(ping)時,銅(tong)(tong)(tong)(tong)即(ji)釋放入(ru)血(xue)(xue)(xue),過量的(de)(de)(de)(de)Cu（II）與-SH結合后在(zai)(zai)紅(hong)(hong)(hong)細胞中(zhong)大量積集,引(yin)起(qi)(qi)酶(mei)系統(tong)的(de)(de)(de)(de)氧(yang)(yang)化(hua)失(shi)活(huo),損傷(shang)紅(hong)(hong)(hong)細胞,增加細胞膜的(de)(de)(de)(de)通(tong)透性,破壞其穩定性并使細胞質(zhi)和(he)(he)(he)細胞器易(yi)于受損,變性血(xue)(xue)(xue)紅(hong)(hong)(hong)蛋(dan)(dan)(dan)白(bai)(bai)增加；另(ling)一(yi)方面,銅(tong)(tong)(tong)(tong)與血(xue)(xue)(xue)紅(hong)(hong)(hong)蛋(dan)(dan)(dan)白(bai)(bai)結合形成Heinz小體(ti)(ti),使細胞內葡萄糖(tang)6一(yi)磷酸(suan)脫(tuo)氫酶(mei)、谷胱(guang)甘肽還(huan)(huan)原酶(mei)失(shi)活(huo),還(huan)(huan)原型谷胱(guang)甘肽減(jian)少,從而(er)導致血(xue)(xue)(xue)紅(hong)(hong)(hong)蛋(dan)(dan)(dan)白(bai)(bai)的(de)(de)(de)(de)自動氧(yang)(yang)化(hua)加劇,變性血(xue)(xue)(xue)紅(hong)(hong)(hong)蛋(dan)(dan)(dan)白(bai)(bai)大量進入(ru)血(xue)(xue)(xue)液(ye),最終(zhong)導致溶血(xue)(xue)(xue)和(he)(he)(he)貧血(xue)(xue)(xue).
氧(yang)化(hua)銅(tong)(tong)見諸于(yu)工業(ye)只要過程中也(ye)最甚，原(yuan)來(lai)在(zai)(zai)我們的現實(shi)生活中也(ye)能(neng)(neng)在(zai)(zai)很多地方見到氧(yang)化(hua)銅(tong)(tong)，比如(ru)用(yong)銅(tong)(tong)制(zhi)的食(shi)用(yong)器皿，或者是佩戴銅(tong)(tong)制(zhi)的首(shou)飾等等。可能(neng)(neng)在(zai)(zai)不(bu)經意間，銅(tong)(tong)長期(qi)暴(bao)露在(zai)(zai)空氣之中，而且(qie)和人(ren)(ren)體皮膚接觸，不(bu)知不(bu)覺中就(jiu)會進(jin)入人(ren)(ren)的身(shen)體，與(yu)血(xue)液結合。氧(yang)化(hua)銅(tong)(tong)對人(ren)(ren)體的傷害需要大家多加(jia)注意。
