2023年5月,國家海(hai)(hai)洋(yang)(yang)局(ju)(ju)天(tian)津海(hai)(hai)洋(yang)(yang)環(huan)(huan)境監測中(zhong)心(xin)(xin)站(zhan)委托世紀(ji)鑫海(hai)(hai)(天(tian)津)環(huan)(huan)境科技有限公司(si)開展南(nan)(nan)港(gang)海(hai)(hai)洋(yang)(yang)環(huan)(huan)境監測站(zhan)土壤污染狀況調查工(gong)作(zuo),國家海(hai)(hai)洋(yang)(yang)局(ju)(ju)天(tian)津海(hai)(hai)洋(yang)(yang)環(huan)(huan)境監測中(zhong)心(xin)(xin)站(zhan)南(nan)(nan)港(gang)海(hai)(hai)洋(yang)(yang)環(huan)(huan)境監測站(zhan)(以下簡稱南(nan)(nan)港(gang)海(hai)(hai)洋(yang)(yang)站(zhan))地(di)(di)塊位于濱(bin)海(hai)(hai)新區開發區南(nan)(nan)港(gang)工(gong)業(ye)區,海(hai)(hai)濱(bin)三(san)(san)道以西,創(chuang)業(ye)二(er)路以北(bei)。四至(zhi)(zhi)范(fan)圍為(wei):東(dong)至(zhi)(zhi)海(hai)(hai)濱(bin)三(san)(san)道、南(nan)(nan)至(zhi)(zhi)創(chuang)業(ye)二(er)路、西至(zhi)(zhi)規(gui)劃(hua)用(yong)(yong)地(di)(di)、北(bei)至(zhi)(zhi)規(gui)劃(hua)用(yong)(yong)地(di)(di),占(zhan)地(di)(di)面積3326.2m2。目前地(di)(di)塊規(gui)劃(hua)為(wei)商業(ye)用(yong)(yong)地(di)(di),即第二(er)類用(yong)(yong)地(di)(di),未(wei)來仍作(zuo)為(wei)第二(er)類用(yong)(yong)地(di)(di)使用(yong)(yong),規(gui)劃(hua)調整后用(yong)(yong)途(tu)為(wei)科研用(yong)(yong)地(di)(di)。
該地(di)塊(kuai)(kuai)歷史上(shang)為圍海造地(di),屬于填海平整(zheng)后開發利用,熟(shu)化后作為南港工(gong)業(ye)(ye)區(qu)建設用地(di)。地(di)塊(kuai)(kuai)內無構建筑(zhu)物(wu)、無生產歷史、無固(gu)廢(fei)堆存等情況,地(di)塊(kuai)(kuai)現狀平坦,長有荒(huang)草。地(di)塊(kuai)(kuai)緊鄰(lin)區(qu)域無生產企(qi)業(ye)(ye)。
地(di)(di)塊面積小于5000平(ping)方(fang)米,依(yi)據(ju)《建設用(yong)地(di)(di)土(tu)(tu)壤(rang)污(wu)(wu)染(ran)狀況調(diao)查(cha)技術導則》(HJ25.1-2019),初(chu)步調(diao)查(cha)過程地(di)(di)塊內(nei)共(gong)(gong)布設4個(ge)土(tu)(tu)壤(rang)采樣(yang)(yang)點位(其中(zhong)(zhong)3個(ge)兼(jian)做地(di)(di)下(xia)(xia)水(shui)采樣(yang)(yang)點),滿足技術要求。共(gong)(gong)采集土(tu)(tu)壤(rang)樣(yang)(yang)品9組(zu)(含平(ping)行樣(yang)(yang)1組(zu)),采集地(di)(di)下(xia)(xia)水(shui)樣(yang)(yang)品4組(zu)(含平(ping)行樣(yang)(yang)1組(zu))。分析檢(jian)測(ce)結果顯示地(di)(di)塊內(nei)土(tu)(tu)壤(rang)樣(yang)(yang)品中(zhong)(zhong)pH值(zhi)介于8.02~8.47之(zhi)間,偏(pian)堿性(xing)。重(zhong)金屬砷、鎘、銅、鉛(qian)、汞、鎳(nie)六種重(zhong)金屬及石(shi)油烴(jing)(C10-C40)有檢(jian)出(chu)(chu),檢(jian)出(chu)(chu)率為100%。六價鉻(ge)、揮發性(xing)有機(ji)物、半揮發性(xing)有機(ji)物檢(jian)測(ce)濃度低于方(fang)法檢(jian)出(chu)(chu)限。土(tu)(tu)壤(rang)中(zhong)(zhong)檢(jian)出(chu)(chu)污(wu)(wu)染(ran)物濃度均滿足《土(tu)(tu)壤(rang)環境質量(liang)建設用(yong)地(di)(di)土(tu)(tu)壤(rang)污(wu)(wu)染(ran)風(feng)險(xian)管(guan)(guan)控標準(試行)》(GB36600-2018)中(zhong)(zhong)的第二類用(yong)地(di)(di)篩選(xuan)值(zhi)。地(di)(di)下(xia)(xia)水(shui)樣(yang)(yang)品檢(jian)出(chu)(chu)數據(ju)滿足《地(di)(di)下(xia)(xia)水(shui)質量(liang)標準》(GB/T14848-2017)中(zhong)(zhong)的IV類標準限值(zhi),地(di)(di)下(xia)(xia)水(shui)中(zhong)(zhong)石(shi)油烴(jing)(C10-C40)檢(jian)出(chu)(chu)濃度均滿足《上海市建設用(yong)地(di)(di)土(tu)(tu)壤(rang)污(wu)(wu)染(ran)狀況調(diao)查(cha)、風(feng)險(xian)評估、風(feng)險(xian)管(guan)(guan)控與修復(fu)方(fang)案編(bian)制、風(feng)險(xian)管(guan)(guan)控與修復(fu)效果評估工作的補(bu)充規(gui)定(試行)》中(zhong)(zhong)石(shi)油烴(jing)的第二類用(yong)地(di)(di)篩選(xuan)值(zhi)。
綜上(shang),本項目地(di)塊內土(tu)壤及地(di)下水(shui)中(zhong)檢測的(de)污(wu)染物含量均未超(chao)過(guo)相應(ying)的(de)限(xian)值標準(zhun)。因此,該(gai)地(di)塊不屬(shu)于(yu)污(wu)染地(di)塊,滿足后期作為科研用地(di)的(de)土(tu)壤環境質量要求,無(wu)需進一步開(kai)展土(tu)壤污(wu)染狀況調查(cha)工作。
