　　土(tu)壤重(zhong)金(jin)屬(shu)(shu)污(wu)(wu)染(ran)(ran)危害較大，來源(yuan)較為(wei)復雜(za)。有空氣污(wu)(wu)染(ran)(ran)沉(chen)降(jiang)，污(wu)(wu)水(shui)入滲，風化(hua)后進(jin)入土(tu)壤的廢棄固體廢物，以及農業生產。重(zhong)金(jin)屬(shu)(shu)污(wu)(wu)染(ran)(ran)來源(yuan)的多樣性也使(shi)切斷(duan)重(zhong)金(jin)屬(shu)(shu)污(wu)(wu)染(ran)(ran)來源(yuan)的問題復雜(za)化(hua)。想要控制(zhi)重(zhong)金(jin)屬(shu)(shu)污(wu)(wu)染(ran)(ran)，首先要知道土(tu)壤是否已經被(bei)污(wu)(wu)染(ran)(ran)了。

　　目前用什么儀器來檢測(ce)土壤中(zhong)的(de)重金屬?

　　用(yong)(yong)土(tu)(tu)壤(rang)(rang)重金屬檢(jian)(jian)(jian)測(ce)(ce)儀(yi)(yi)可(ke)以很容易地做到這一點(dian)。重金屬檢(jian)(jian)(jian)測(ce)(ce)儀(yi)(yi)的(de)形狀類似于手持(chi)吹(chui)風機。在檢(jian)(jian)(jian)測(ce)(ce)過(guo)(guo)程(cheng)中，通過(guo)(guo)將儀(yi)(yi)器(qi)與土(tu)(tu)壤(rang)(rang)表面連接，可(ke)以自動分析土(tu)(tu)壤(rang)(rang)中各種重金屬的(de)含(han)量。整(zheng)個分析過(guo)(guo)程(cheng)不超過(guo)(guo)80秒。儀(yi)(yi)器(qi)體(ti)(ti)積小(xiao)，重量輕，便于攜帶到現(xian)場進(jin)行土(tu)(tu)壤(rang)(rang)檢(jian)(jian)(jian)測(ce)(ce)。適用(yong)(yong)于田間土(tu)(tu)壤(rang)(rang)、砂土(tu)(tu)、污(wu)泥、固體(ti)(ti)廢棄物(wu)、土(tu)(tu)壤(rang)(rang)、泥漿(jiang)等。

　　應用便攜式土壤(rang)(rang)重(zhong)(zhong)(zhong)金(jin)(jin)屬(shu)檢測(ce)(ce)儀(yi)(yi)(yi)檢測(ce)(ce)土壤(rang)(rang)中(zhong)重(zhong)(zhong)(zhong)金(jin)(jin)屬(shu)含量(liang)是土壤(rang)(rang)環境研(yan)究和(he)污染防治的重(zhong)(zhong)(zhong)要依據。該儀(yi)(yi)(yi)器也(ye)是各實(shi)驗室、化(hua)驗室的常規檢測(ce)(ce)設備(bei)。土壤(rang)(rang)重(zhong)(zhong)(zhong)金(jin)(jin)屬(shu)檢測(ce)(ce)儀(yi)(yi)(yi)器的投入和(he)應用為土壤(rang)(rang)重(zhong)(zhong)(zhong)金(jin)(jin)屬(shu)檢測(ce)(ce)提(ti)供了(le)高(gao)精(jing)(jing)度、低成(cheng)本、短(duan)時間的解決方案，有效提(ti)高(gao)了(le)土壤(rang)(rang)重(zhong)(zhong)(zhong)金(jin)(jin)屬(shu)檢測(ce)(ce)的檢測(ce)(ce)精(jing)(jing)度和(he)效率。

　　隨著工業化的發展(zhan)，越(yue)來(lai)越(yue)多的重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)物質有了“機會(hui)"進入我(wo)們的生存環境。目前(qian)，重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)監測儀(yi)(yi)器也開始受(shou)到越(yue)來(lai)越(yue)多的關注。土壤(rang)中重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)含量過高(gao)，不僅會(hui)阻礙植物的生長發育，甚至土壤(rang)中的一(yi)些重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)元素還會(hui)轉化為毒性(xing)更大的甲基化合(he)物，有的還會(hui)通過食物鏈以有害濃度積累(lei)在人體內，還會(hui)嚴重(zhong)(zhong)(zhong)危害人體健(jian)康。因此，推廣和使用土壤(rang)重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)檢測儀(yi)(yi)是防治重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)污(wu)染的重(zhong)(zhong)(zhong)要組成(cheng)部分。
