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)最多的時候是在工業中(zhong),那么生活中(zhong)氧(yang)化(hua)銅(tong)對人體的傷害有(you)哪些呢?我們一(yi)起來了解一(yi)下。
銅在人(ren)體中(zhong)屬于(yu)微量(liang)元素,食用(yong)的氧化(hua)銅在胃(wei)里與胃(wei)酸(suan)反應生(sheng)成CuCl2,就(jiu)會(hui)被(bei)人(ren)體吸(xi)收,Cu2+一(yi)旦進入(ru)人(ren)體血(xue)(xue)液(ye)(ye)超標的話(hua)就(jiu)會(hui)造成重金屬元素中(zhong)毒,主(zhu)要是(shi)可以引(yin)起(qi)體內的蛋(dan)白(bai)(bai)質(zhi)變(bian)性(xing)(xing)。然(ran)而銅的另(ling)一(yi)毒理表現是(shi)損傷紅(hong)(hong)(hong)(hong)(hong)細(xi)(xi)(xi)(xi)(xi)胞(bao)引(yin)起(qi)溶血(xue)(xue)和(he)(he)貧(pin)血(xue)(xue)。通常氧化(hua)銅進入(ru)體內后主(zhu)要在肝(gan)臟中(zhong)累積(ji),一(yi)旦超過(guo)肝(gan)臟的處理水(shui)平時,銅即(ji)釋放(fang)入(ru)血(xue)(xue),過(guo)量(liang)的Cu(II)與-SH結合后在紅(hong)(hong)(hong)(hong)(hong)細(xi)(xi)(xi)(xi)(xi)胞(bao)中(zhong)大(da)量(liang)積(ji)集,引(yin)起(qi)酶系統的氧化(hua)失(shi)活,損傷紅(hong)(hong)(hong)(hong)(hong)細(xi)(xi)(xi)(xi)(xi)胞(bao),增加(jia)細(xi)(xi)(xi)(xi)(xi)胞(bao)膜(mo)的通透性(xing)(xing),破(po)壞(huai)其穩定性(xing)(xing)并使細(xi)(xi)(xi)(xi)(xi)胞(bao)質(zhi)和(he)(he)細(xi)(xi)(xi)(xi)(xi)胞(bao)器(qi)易于(yu)受損,變(bian)性(xing)(xing)血(xue)(xue)紅(hong)(hong)(hong)(hong)(hong)蛋(dan)白(bai)(bai)增加(jia);另(ling)一(yi)方面,銅與血(xue)(xue)紅(hong)(hong)(hong)(hong)(hong)蛋(dan)白(bai)(bai)結合形成Heinz小(xiao)體,使細(xi)(xi)(xi)(xi)(xi)胞(bao)內葡萄糖6一(yi)磷酸(suan)脫氫酶、谷胱(guang)甘肽還原酶失(shi)活,還原型(xing)谷胱(guang)甘肽減少,從而導致血(xue)(xue)紅(hong)(hong)(hong)(hong)(hong)蛋(dan)白(bai)(bai)的自(zi)動氧化(hua)加(jia)劇,變(bian)性(xing)(xing)血(xue)(xue)紅(hong)(hong)(hong)(hong)(hong)蛋(dan)白(bai)(bai)大(da)量(liang)進入(ru)血(xue)(xue)液(ye)(ye),最終導致溶血(xue)(xue)和(he)(he)貧(pin)血(xue)(xue).
氧化銅(tong)(tong)見諸于工業只要(yao)過程(cheng)中(zhong)也(ye)最甚(shen),原來在我們(men)的(de)現實生(sheng)活中(zhong)也(ye)能(neng)在很多(duo)地方(fang)見到氧化銅(tong)(tong),比如用(yong)銅(tong)(tong)制的(de)食(shi)用(yong)器皿,或者是(shi)佩戴銅(tong)(tong)制的(de)首飾等(deng)(deng)等(deng)(deng)。可能(neng)在不(bu)經(jing)意(yi)間(jian),銅(tong)(tong)長(chang)期暴露(lu)在空氣(qi)之(zhi)中(zhong),而且和人(ren)體(ti)皮膚接觸,不(bu)知不(bu)覺中(zhong)就會(hui)進入人(ren)的(de)身(shen)體(ti),與血液結合(he)。氧化銅(tong)(tong)對人(ren)體(ti)的(de)傷(shang)害需要(yao)大家多(duo)加注意(yi)。
