8、污泥有益健康論
費(fèi)城的污泥處置計(jì)劃經(jīng)理William Toffey有過(guò)一段十分慷慨激昂的說(shuō)辭：暴露于污泥中對(duì)你的健康有好處。科學(xué)證明所謂“衛(wèi)生假說(shuō)”即過(guò)去所說(shuō)的“清潔兒童綜合癥”是有道理的，我們的年輕人要是不接觸污物和糞便，身體就不會(huì)產(chǎn)生保護(hù)我們免受過(guò)敏原和毒素攻擊的免疫反應(yīng)，如果這孩子太干凈了，過(guò)敏、哮喘和癌癥的發(fā)生率會(huì)更高。我相信的理論是：如果污泥殺不死你，只會(huì)讓你更強(qiáng)壯。……
說(shuō)這話，首先是承認(rèn)了污泥是臟東西，會(huì)帶來(lái)污染，但503的神奇之處在于，這污染還對(duì)你的健康有利。一句話：環(huán)境污染無(wú)害。如此奇談怪論，我本來(lái)以為只有中國(guó)能聽(tīng)到的。就像有人說(shuō)常吃毒膠囊、三鹿粉、瘦肉精、地溝油、一滴香、鎘大米、石蠟鍋、藥火腿、雙氧翅、陳化糧、增稠蜜、紅心蛋、糖精棗、鋁饅頭、硫銀耳、蘇丹紅、甲醇酒、紙腐竹、硫磺椒、毒米線、避孕鱔……能百毒不侵一樣！
有句老話說(shuō)：黃鼠狼專(zhuān)咬病鴨子。能夠處置污泥的地方一定不會(huì)在發(fā)達(dá)的高等社區(qū)，就像地溝油也不會(huì)進(jìn)入特供商店一樣。令人感到悲哀的是，弱勢(shì)群體總是犧牲者。
9、中國(guó)是否要學(xué)習(xí)美國(guó)
一個(gè)不得不問(wèn)的問(wèn)題是，中國(guó)如果也制定一部類(lèi)似的503，情況會(huì)怎樣？
可以先不管我國(guó)工業(yè)發(fā)展水平方面的差距，可以忽略我國(guó)高能耗、高污染工業(yè)的比例高所帶來(lái)的污泥中污染物濃度高的問(wèn)題，也可以忽略我國(guó)因人口多，市政污泥發(fā)生總量比美國(guó)多的問(wèn)題。僅從人口與土地面積方面考慮，這樣做的風(fēng)險(xiǎn)如何呢？

如果如美國(guó)所發(fā)生的情況一樣，因施用污泥而造成土地污染繼而引起周邊居民的疫病流行，中國(guó)的風(fēng)險(xiǎn)將是美國(guó)的數(shù)十倍乃至數(shù)百倍，因?yàn)橐恍┺r(nóng)村的人均耕地連全國(guó)鄉(xiāng)村人口平均耕地面積的十分之一都不到。
三、結(jié)語(yǔ)
水往低處流。由于土地施用的閘口比焚燒、填埋低得多，因此美國(guó)503法規(guī)事實(shí)上是污泥土地施用的代名詞。
503的操盤(pán)手主要是兩個(gè)人：EPA OW水辦的Dr. Alan Rubin，USDA農(nóng)業(yè)部的Dr. Rufus Chaney。EPA和USDA的“精誠(chéng)合作”，才有了503的出臺(tái)。
一個(gè)傾倒到水體里對(duì)水體有害，焚燒產(chǎn)生煙氣會(huì)對(duì)空氣有害的物質(zhì)，如何到了土壤里就全都如泥牛入海，徹底消失了呢？這是一個(gè)常識(shí)問(wèn)題，不是運(yùn)用數(shù)學(xué)工具就可以歸零掉的。對(duì)此，Rubin博士的說(shuō)法是：這就是“污泥魔法”(“Sludge Magic”)。
國(guó)內(nèi)同仁有的已經(jīng)注意到503存在反對(duì)意見(jiàn)（余杰等《污泥農(nóng)用在我國(guó)污泥處置中的應(yīng)用前景分析》），但專(zhuān)家輿論總體上還是贊成污泥農(nóng)用、園林綠化的。
早有讀者注意到，迄今為止筆者一直避免談?wù)摱逊�，這是因?yàn)槲矣X(jué)得堆肥只是土地施用的一種前處理技術(shù)，談?wù)摱逊什豢赡懿徽勍寥腊踩珕?wèn)題，而這是一個(gè)非常復(fù)雜而嚴(yán)肅的題目。我一向贊同業(yè)內(nèi)同行提出的有機(jī)物還田、長(zhǎng)期使用化肥可能導(dǎo)致土壤板結(jié)、推薦自然生態(tài)循環(huán)等命題。但讀了這么多有關(guān)美國(guó)503法規(guī)的文獻(xiàn)后，更覺(jué)得審慎是必要的，畢竟中國(guó)不像美國(guó)，因人口密度問(wèn)題，我們所面臨的風(fēng)險(xiǎn)要大得多。
在遲遲拿不出一部“中國(guó)版”503這個(gè)問(wèn)題上，農(nóng)業(yè)部以它的“不作為”無(wú)疑倒是做了一件好事。農(nóng)業(yè)部未必不想“開(kāi)閘放水”，但污灌所造成大量農(nóng)田損害已是不爭(zhēng)的事實(shí)，農(nóng)業(yè)部1992、2005兩次提高污灌標(biāo)準(zhǔn)，想來(lái)是事出有因的。
歐盟個(gè)別國(guó)家已對(duì)污泥土地施用采取了禁止的政策，如比利時(shí)、盧森堡、挪威和瑞士。對(duì)此，我覺(jué)得中國(guó)也未必需要照搬，畢竟中國(guó)有著廣大的未受工業(yè)污染的小城市和鄉(xiāng)鎮(zhèn)。
污泥的土地利用控制指標(biāo)到底應(yīng)該怎樣？其實(shí)可以做這樣一個(gè)簡(jiǎn)單比喻：如果按照國(guó)標(biāo)的食用成品油9項(xiàng)指標(biāo)來(lái)評(píng)測(cè)，地溝油絕對(duì)是合格產(chǎn)品。地溝油至今畢竟也沒(méi)有“可被科學(xué)證實(shí)對(duì)人體產(chǎn)生危害的案例被記錄”。但為什么消費(fèi)者對(duì)地溝油深?lèi)和唇^，在感情上難以接受呢？這應(yīng)該是常識(shí)，而非標(biāo)準(zhǔn)的問(wèn)題。
503之“過(guò)”在于，它采用為污泥改名和頒布一套貌似科學(xué)實(shí)則明修棧道、暗渡陳倉(cāng)的“標(biāo)準(zhǔn)限值”，想讓公眾相信它是徹底無(wú)害和安全的，而沒(méi)有采取實(shí)事求是、負(fù)責(zé)的態(tài)度告知公眾特別是消費(fèi)者其風(fēng)險(xiǎn)，從而給環(huán)境和少數(shù)居民帶來(lái)不可逆轉(zhuǎn)的傷害。
套用證監(jiān)會(huì)和證劵公司撇清責(zé)任的一句名言，“股市有風(fēng)險(xiǎn)，投資需謹(jǐn)慎”。誰(shuí)都知道有風(fēng)險(xiǎn)，但入市的股民還是那么多，原因在于大家都有自己的判斷，投資者自己一定是看好這個(gè)賺錢(qián)機(jī)會(huì)的。污泥處置也一樣，但這話可能應(yīng)改成“土地施用有風(fēng)險(xiǎn)，政策制定需謹(jǐn)慎”比較合適。政策如果錯(cuò)了，退可就退不回來(lái)了。成百萬(wàn)公頃被污染的土地如何治理，誰(shuí)來(lái)治理，這可是連美國(guó)人都不敢想象的事情。美國(guó)EPA之所以使用種種不堪手段來(lái)捍衛(wèi)503，想來(lái)就是為此。成立專(zhuān)門(mén)的救火隊(duì)，扣押不利的研究結(jié)果和論文，與利益集團(tuán)合力打壓反對(duì)者和不同的聲音，偽造數(shù)據(jù)，大搞御用偽科學(xué)研究，這些似乎已經(jīng)大大超越了其政府職能。
關(guān)于503的研究當(dāng)然還應(yīng)該深入下去，相信真相自明，大家都會(huì)有自己獨(dú)立的判斷。

【后記】
本文寫(xiě)作花了不少時(shí)間，看了好幾本書(shū)，幾百篇論文，查閱的資料無(wú)數(shù)。寫(xiě)完了，心情也久久平靜不下來(lái)。最大的感慨是，真正的有良心的環(huán)保研究者原來(lái)也都是弱勢(shì)群體！
在博客版中，我將列出一個(gè)詳細(xì)的參考書(shū)目，建議讀者自行研究一下。如果你認(rèn)可本文的分析和觀點(diǎn)，應(yīng)該對(duì)那些遭受污染傷害而失去健康甚至生命的人們表示同情，為那些堅(jiān)持真理進(jìn)行嚴(yán)肅研究而拒絕充當(dāng)御用工具的研究者們表示敬意（當(dāng)然，自己今后也別搞什么“自主”的假發(fā)明、假課題、假論文了）。在我心目中這兩位是美國(guó)環(huán)保界的真正英雄：David L. Lewis, Hugh Kaufman.
