其癥狀是出現(xiàn)兩眼高度羞明、流淚、異物感、刺痛、眼瞼***、痙攣、并伴有***和視物模糊。焊接煙塵的危害焊接過程中會(huì)產(chǎn)生大量的金屬焊接粉塵，焊接產(chǎn)生的金屬粉直徑很小，較容易吸肺部，因直徑很小很難排出體外，故發(fā)生病變。焊接電流強(qiáng)度越大粉塵濃度越高。在焊接粉塵濃度較大的情況下，又沒有相應(yīng)的排塵措施時(shí)，長期接觸焊接粉塵能引起焊工塵肺、錳中毒和金屬熱等職業(yè)疾病。生殖毒性，近10年來國內(nèi)外開展了一些關(guān)于電焊作業(yè)生殖毒性的研究，主要涉及男工**質(zhì)量、女工生殖結(jié)局及損害機(jī)制。研究表明：電焊女工月經(jīng)的經(jīng)量增加、周期縮短、經(jīng)期延長、白帶增加，自然流產(chǎn)、早產(chǎn)、痛經(jīng)、均較對(duì)照組高。錳中毒男工**外觀呈均勻灰白色，PH值正常，平均液化時(shí)間比對(duì)照組延長。檢驗(yàn)結(jié)果證明，錳中毒男工平均一次**量、精子總數(shù)、精子存活率及活動(dòng)精子率均比對(duì)照組下降，錳中毒男工精子畸形率明顯高于對(duì)照組。認(rèn)為金屬錳能夠影響男工生精系統(tǒng)，對(duì)精子的發(fā)育有直接毒作用，并能殺傷精子，從而引起男性**質(zhì)量的改變。國外也有報(bào)道電焊作業(yè)工人性***分泌改變，精子質(zhì)量下降，但對(duì)子代的性別比例沒有影響有害氣體的危害在焊接電弧高溫和強(qiáng)烈紫外線的作用下。山東SKD-11焊絲價(jià)格焊絲應(yīng)放在木托盤上，不能將其直接放在地板或緊貼墻壁。</p><div
