class="NyNewsdetail_tips">更新時(shí)間：2023-08-26 點(diǎn)擊次數(shù)：567</div> <div id="99ypdan7f2" class="NyNewsdetail_con"> <div>惡臭是所有刺激人體嗅覺(jué)器官、引起不愉快以及損壞生活環(huán)境的氣體物質(zhì)。<br style="margin: 0px; padding: 0px;"/> </div><div>迄今憑人的嗅覺(jué)就能感覺(jué)到的惡臭物質(zhì)就有4000多種，其中對(duì)人體健康危害較大的有幾十種。有的散發(fā)出臭魚(yú)味，如胺類(lèi)；有的刺鼻，如氨類(lèi)和醛類(lèi)；有的放出臭雞蛋味，如硫化氫；有的類(lèi)似爛洋蔥或爛洋白菜味等等。惡臭物質(zhì)使人呼吸不暢，嘔吐，煩躁不安，頭暈?zāi)X脹，甚至把人熏倒，濃度高時(shí)，還會(huì)使人窒息而死。<br style="margin: 0px; padding: 0px;"/> </div><div>　　惡臭物質(zhì)分布很廣，影響范圍大，已成為一些國(guó)家的公害。惡臭物質(zhì)多來(lái)源于化學(xué)、制藥、制紙、制革、肥料、食品、鑄造等工業(yè)。惡臭對(duì)人的呼吸系統(tǒng)、循環(huán)系統(tǒng)、消化系統(tǒng)、內(nèi)分泌系統(tǒng)、神經(jīng)系統(tǒng)都有不同程度的損害。惡臭還會(huì)使人煩躁不安，工作效率減低，判斷力和記憶力下降。高濃度惡臭物質(zhì)突然襲擊，有時(shí)會(huì)把人當(dāng)場(chǎng)熏倒，造成事故。<br style="margin: 0px; padding: 0px;"/> </div><div>　　惡臭危害主要有六個(gè)方面：<br style="margin: 0px; padding: 0px;"/> </div><div>　　①危害呼吸系統(tǒng)。人們突然聞到惡臭，就會(huì)產(chǎn)生反射性的抑制吸氣，使呼吸次數(shù)減少，深度變淺，甚至*停止吸氣，即所謂“閉氣"，妨礙正常呼吸功能。<br style="margin: 0px; padding: 0px;"/> </div><div>　　②危害循環(huán)系統(tǒng)。隨著呼吸的變化，會(huì)出現(xiàn)脈搏和血壓的變化。如氨等刺激性臭氣會(huì)使血壓出現(xiàn)先下降后上升，脈搏先減慢后加快的現(xiàn)象。<br style="margin: 0px; padding: 0px;"/> </div><div>　?、畚：ο到y(tǒng)。經(jīng)常接觸惡臭，會(huì)使人厭食、甚至嘔吐，進(jìn)而發(fā)展為消化功能減退。<br style="margin: 0px; padding: 0px;"/> </div><div>　?、芪：?nèi)分泌系統(tǒng)。經(jīng)常受惡臭刺激，會(huì)使內(nèi)分泌系統(tǒng)的分泌功能紊亂，影響機(jī)體的代謝活動(dòng)。<br style="margin: 0px; padding: 0px;"/> </div><div>　?、菸：ι窠?jīng)系統(tǒng)。長(zhǎng)期受到一種或幾種低濃度惡臭物質(zhì)的刺激，會(huì)引起嗅覺(jué)脫失、嗅覺(jué)疲勞等障礙?！熬寐劧恢涑?，使嗅覺(jué)喪失了第一道防御功能，但腦神經(jīng)仍不斷受到刺激和損傷，最后導(dǎo)致大腦皮層興奮和抑制的調(diào)節(jié)功能失調(diào)。<br style="margin: 0px; padding: 0px;"/> </div><div>　?、迣?duì)精神的影響。惡臭使人精神煩躁不安，思想不集中，工作效率減低，判斷力和記憶力下降，影響大腦的思考活動(dòng)。<br style="margin: 0px; padding: 0px;"/> </div><div>　　高濃度惡臭物質(zhì)的突然襲擊，有時(shí)會(huì)把人當(dāng)場(chǎng)熏倒，造成事故。例如在日本川崎市，1961年8～9月就曾連續(xù)發(fā)生三次惡臭公害事件，都是由一家工廠夜間排放一種含硫醇的廢油引起的。惡臭擴(kuò)散到距排放源20多公里的地方，近處有人當(dāng)場(chǎng)被熏倒；遠(yuǎn)處有人在熟睡中被熏醒。還有人嘔吐、眼睛疼痛等等。<br
