河蜆作為廣泛分布于世界各國的典型底棲生物，由于其活動(dòng)性低、濾食性等特征被廣泛用作指示生物研究多種水體污染物的生物有效性。但迄今為止，尚沒有系統(tǒng)論述污染水體中河蜆生物毒性響應(yīng)的研究進(jìn)展。為此，本文從污染物種類、測試指標(biāo)、試驗(yàn)參數(shù)等角度探討了過去30多年間河蜆在氨、重金屬、有機(jī)污染物生物富集及生物毒性效應(yīng)等方面的研究過程及主要成果。以往研究主要以河蜆生物體內(nèi)累積、形態(tài)學(xué)及行為學(xué)觀察、生化指標(biāo)、代謝組學(xué)、基因完整性等指標(biāo)表征污染水體的生物毒性效應(yīng)，并隨著分子生物學(xué)的發(fā)展已逐步由多指標(biāo)全面表征代替單一指標(biāo)測試。此外，現(xiàn)有研究多偏重于重金屬和持久性有機(jī)污染物，對氨、新型污染物及納米材料的河蜆生物毒性效應(yīng)探討尚處于起步階段。河蜆在自然水體污染狀況評估、污染水體的生物修復(fù)、水體毒性預(yù)測等方面具有較高適用性，但河蜆在沉積物毒性鑒定評估(TIE, Toxicity Identification and Evaluation)中的應(yīng)用研究依然較為缺乏，有待進(jìn)一步開展。

Abstract: As a typical benthonic species, Corbicula fluminea is widely used for biomonitoring freshwater pollution due to its sessile and filter-feeding characteristics. However, there is few reports reviewing the progress about biological toxic response and bioaccumulation for contaminants of C. fluminea in aquatic environment. Therefore, this study summarized the main achievements about the effects of pollutants (ammonia, trace metals, organic contaminants) on freshwater invertebrates C. fluminea in terms of pollutant species, test index, test medium and test duration. The results indicated that the common biomonitoring techniques applied in C. fluminea study could be classified as bioaccumulation, morphology, behavior observation, biochemical index alterations, metabonomics measure and genetic integrity changes. With the development of molecular biology, the use of single biomarker is gradually replaced by multi-biomarker approach. Furthermore, existing researches mainly focus on heavy metals and persistent organic pollutants, whereas studies on ammonia, emerging contaminants and nanomaterials are still in the initial stage. Overall, C. fluminea is a useful species for evaluating aquatic pollution, bioremediation, toxicity prediction. Studies on the application of C. fluminea in the area of sediment Toxicity Identification and Evaluation (TIE), by contrast, are still scarce and need extensive investigations.

水體沉積物中具有明顯生物和生態(tài)效應(yīng)的污染物種類繁多，近年來，污染物的生物毒性響應(yīng)特征、過程與機(jī)制逐漸成為國內(nèi)外研究的熱點(diǎn)。生物毒性測試由于可反映污染物的生物可利用性，是評估水體綜合污染的有效手段之一，是化學(xué)分析和底棲生物群落結(jié)構(gòu)評價(jià)方法的有益補(bǔ)充[1]。雙殼貝類作為一類世界性分布的沿岸底棲水生動(dòng)物，在污染物的生物富集和傳遞過程中起著重要作用，可通過食用影響人體健康，已成為環(huán)境毒理學(xué)研究關(guān)注的對象[20]。

河蜆作為一種典型淡水底棲雙殼貝類，具有活動(dòng)性低、易于培養(yǎng)、經(jīng)濟(jì)實(shí)用、分布廣泛等特征，對污染物具有較強(qiáng)的富集性，廣泛應(yīng)用于水體尤其是沉積物毒性效應(yīng)評價(jià)和鑒定研究[2]。河蜆原產(chǎn)于亞洲、非洲以及澳大利亞[3]，由于其入侵性，目前亦廣泛分布于北美、南美以及歐洲等地[4-5]。美國[11,34,42,53-60,88,93,95-101]、中國[18-19,29,40,45-52,61-62,92]、法國[2,6,13-16,28,33,35,37-38,43-44,63-77,86,107-108]、德國[30,32]、英國[12]、葡萄牙[7-10,21,39,41,94,102]、阿根廷[79-80,90,103-104]、巴西[17,36,81,85,105]、西班牙[83,87]、塞爾維亞[91]、馬來西亞[82]、伊拉克[78]、菲律賓[106]等國家均開展了河蜆在污染物生物毒性響應(yīng)的研究。

河蜆對污染物生物毒性響應(yīng)研究主要包括生物富集、生化指標(biāo)改變、形態(tài)學(xué)、行為學(xué)觀察、野外種群及群落水平分布調(diào)查等[1]。也有研究將其作為哨兵生物(sentinel organism)，應(yīng)用于貽貝污染物監(jiān)測項(xiàng)目(NCCOS)等常規(guī)生物監(jiān)測程序探討[60]。整體上，河蜆作為水體尤其是沉積物污染受試生物的指示性應(yīng)用研究尚處于發(fā)展階段。近幾年，相關(guān)研究逐漸涉及到組織學(xué)、組織化學(xué)、組織病理學(xué)[7-11]，代謝組學(xué)[12]和基因表達(dá)[13-19]等分子生物學(xué)方面。各種生物效應(yīng)、毒理學(xué)指標(biāo)也隨著分子生物學(xué)及相關(guān)分析檢測儀器技術(shù)的發(fā)展而快速更新。

為系統(tǒng)認(rèn)識(shí)河蜆對污染物的生物毒性響應(yīng)特征，本文基于1983—2016年國外文獻(xiàn)中有關(guān)河蜆研究成果，結(jié)合前期已發(fā)表研究成果[20]，從水體污染物類型、研究方法、指標(biāo)體系等方面綜合歸納整理河蜆的污染物生物富集及生物毒性效應(yīng)研究現(xiàn)狀及發(fā)展歷程。結(jié)果可為河蜆對水體及沉積物中污染物的生物富集、生物毒性鑒定研究提供參考。

研究過程中，根據(jù)污染物種類、試驗(yàn)參數(shù)、測試指標(biāo)進(jìn)行分類，具體技術(shù)路線見圖-1。

1 氨污染水體中河蜆的生物毒性響應(yīng)研究(The biological toxicity response of Corbicula fluminea in ammonia contaminated water)

研究表明，氨對不同水生無脊椎動(dòng)物具有不同程度的毒性，但是氨毒性可能是致命的[21]。有學(xué)者對多種淡水貝類進(jìn)行氨毒性實(shí)驗(yàn)，得出不同貝類的96 h半致死濃度(11.53～23.1 mg·L-1)[22-24]。Cooper等[25-27]曾研究人工模擬河流中河蜆大面積死亡時(shí)軟體組織腐敗所釋放氨對本土物種淡水貽貝的影響。但是氨對河蜆本身的急慢性毒性效應(yīng)卻報(bào)道較少。據(jù)作者檢索，國外報(bào)道中僅發(fā)現(xiàn)一篇文獻(xiàn)，論述長期慢性氨污染對河蜆的多種生物標(biāo)志物產(chǎn)生的亞致死影響研究(表1)[21]。研究發(fā)現(xiàn)，采自污染河口區(qū)的河蜆由于長期處于污染環(huán)境中，其各項(xiàng)酶活性指標(biāo)均表現(xiàn)出較高背景值，因此受1 mg·L-1含氨水污染后，各項(xiàng)指標(biāo)并未表現(xiàn)出明顯差異。這說明長期處于污染水域會(huì)增強(qiáng)河蜆對氨的耐受性，有利于其入侵行為。由于水生生物的內(nèi)源排放及人類工農(nóng)業(yè)快速發(fā)展所引起的外源污染，氨氮已成為水環(huán)境中最普遍的污染物之一，但是目前水體中氨污染引起的河蜆毒性響應(yīng)研究甚少，此類研究有待進(jìn)一步加強(qiáng)。

2 重金屬污染水體中河蜆的生物毒性響應(yīng)研究(The biological toxicity response of Corbicula fluminea in metal contaminated water)

表2匯總了1983—2016年間的65篇在國外期刊發(fā)表的有關(guān)河蜆對重金屬的生物毒性響應(yīng)研究進(jìn)展。從表2可以看出，已有大量研究探討了重金屬污染水體中河蜆的生物毒性響應(yīng)。在研究所屬國家分類上，法國有相對較全面的研究。波爾多大學(xué)研究團(tuán)隊(duì)從1997年到2014年間發(fā)表27篇文獻(xiàn)。美國、中國、德國、英國、阿根廷、巴西、馬來西亞、伊拉克、西班牙等在河蜆對污染物生物毒性響應(yīng)方面也均有研究。研究過程經(jīng)歷了從早期的河蜆不同軟體組織對重金屬的富集量、行為學(xué)特征(閉殼響應(yīng)、呼吸活性)[34,37,44,53-54,58,63,66-71,78-80]，到后期的生物標(biāo)志物多指標(biāo)綜合研究，如：生化指標(biāo)中丙二醛(MDA)、金屬硫蛋白(MT)、谷胱甘肽(GSH)含量測定[7-10]，抗氧化系統(tǒng)中過氧化氫酶(CAT)、超氧化物歧化酶(SOD)等酶活性的測定[9-10,43,61]，蛋白定量驗(yàn)證中MXR蛋白、熱休克蛋白Hsp60等的測定[36,72-74]，再到分子標(biāo)記物中基因表達(dá)水平的測定研究[13-16]。也有很多研究，探討了不同非生物因子如pH、溫度、溶解氧(DO)、CO2含量等因素影響下不同重金屬對河蜆的生物毒性效應(yīng)[37,43,66-68,70-71]。除以上指標(biāo)外，還對污染物影響下河蜆消化腺病變、消化腺細(xì)胞內(nèi)污染物顆粒及溶酶體系統(tǒng)變化和中性脂質(zhì)含量等組織學(xué)、組織化學(xué)及組織病理學(xué)進(jìn)行研究[7-10,15]。由于雙殼類消化腺在調(diào)整和消除外源有害物質(zhì)中起到關(guān)鍵作用，且消化道管壁上皮細(xì)胞對許多金屬及準(zhǔn)金屬污染物的損害影響較敏感[9]，因此以往研究常對該器官進(jìn)行組織學(xué)分析。英國學(xué)者Nicole等[12]還對河蜆代謝組學(xué)進(jìn)行分析，探究Cd和Zn對不同大小河蜆代謝物的影響。整體而言，除法國、葡萄牙、巴西學(xué)者涉及到一些組織學(xué)觀察、生化指標(biāo)響應(yīng)、蛋白定量驗(yàn)證、及基因表達(dá)方面的研究，其他國家研究多處于基礎(chǔ)階段，多采用河蜆體內(nèi)污染物富集量、死亡率、掘穴行為等常規(guī)指標(biāo)進(jìn)行表征。我國學(xué)者對重金屬污染水體中河蜆的生物毒性響應(yīng)開展了大量研究[20,29,40,61-62,109-110]，對河蜆的金屬富集、行為學(xué)觀察、生化指標(biāo)改變3個(gè)方面進(jìn)行了污染物生物毒性響應(yīng)研究，但是對于重金屬污染，還未展開組織學(xué)、代謝組學(xué)、基因水平的研究。

在重金屬種類上，常見重金屬Cd、Hg、Cu、Zn、Se、U、Ni、Pb等對河蜆的生物毒性效應(yīng)均有研究，而Cd作為對淡水生物群落毒性最強(qiáng)[28]的污染物，研究文獻(xiàn)最多。在79篇文獻(xiàn)中有46篇將其列為研究對象(表2)。還有少量研究探討金屬放射性同位素[28-29]、稀土元素[30]的生物毒性。對于近年來新的環(huán)境挑戰(zhàn)，也有學(xué)者對納米材料尤其是納米金屬進(jìn)行雙殼類生物毒性實(shí)驗(yàn)。葡萄牙學(xué)者對納米金剛石及納米TiO2的河蜆生物毒性研究[9-10]表明，納米材料影響河蜆的氧化應(yīng)激系統(tǒng)且引起了消化腺上皮細(xì)胞的組織學(xué)變化。整體上納米材料對河蜆生物毒性研究較少。隨著納米材料應(yīng)用的增多，此類研究有必要繼續(xù)完善，為環(huán)境風(fēng)險(xiǎn)評估提供可靠信息[31]。

在基質(zhì)選取上，現(xiàn)有研究主要以現(xiàn)場監(jiān)測和室內(nèi)模擬模式開展水相(含沉積物孔隙水、沉積物上覆水)、全沉積物相實(shí)驗(yàn)研究(表2)。其中，水相研究中包括天然水體的原位水相實(shí)驗(yàn)和實(shí)驗(yàn)室配水的室內(nèi)模擬實(shí)驗(yàn)。相對而言，水相實(shí)驗(yàn)易于操作控制，現(xiàn)有研究多采用水相加標(biāo)進(jìn)行模擬實(shí)驗(yàn)研究，針對全沉積物的毒性效應(yīng)研究較少(約占6%)。然而，河蜆作為底棲生物直接接觸沉積物，可通過鰓攝取沉積物間隙水中游離態(tài)污染物，也可通過攝食途徑取食富含污染物的顆粒物而累積污染物。因此，水相實(shí)驗(yàn)難以全面、直接反映沉積物的污染和生物毒性。在生物毒性效應(yīng)研究中，實(shí)驗(yàn)基質(zhì)的選取還需以全沉積物為主要基質(zhì)。

從實(shí)驗(yàn)周期角度來分析，根據(jù)研究類別的不同，野外監(jiān)測及原位試驗(yàn)研究通常周期較長。野外監(jiān)測考慮河蜆富集的時(shí)空分布，通常進(jìn)行不同季節(jié)多次采樣[32-34]；原位試驗(yàn)[35]由于污染物濃度的不可控性而需進(jìn)行長期富集實(shí)驗(yàn)。由于河蜆對重金屬具有較強(qiáng)的富集能力，除少數(shù)研究對河蜆進(jìn)行體外急性(96 h)毒性實(shí)驗(yàn)外[36]，重金屬對河蜆的生物毒性及河蜆對重金屬的解毒機(jī)制[14, 37-38]研究多采用慢性(1個(gè)月～1年)毒性實(shí)驗(yàn)。

整體上，河蜆在水體重金屬污染中的應(yīng)用主要集中在4個(gè)方面：(1)通過野外監(jiān)測評估實(shí)際水生環(huán)境中重金屬污染情況；(2)研究河蜆對富含重金屬水體的生物修復(fù)能力，探討重金屬污染區(qū)域的生物修復(fù)技術(shù)；(3)重金屬對河蜆健康影響的毒理學(xué)機(jī)理研究；(4)毒性預(yù)測——依據(jù)河蜆生物監(jiān)測得出的毒理學(xué)數(shù)據(jù)建立生物模型來評估及預(yù)測污染物潛在生態(tài)風(fēng)險(xiǎn)。

在野外監(jiān)測上，大量學(xué)者通過野外監(jiān)測分析河蜆體內(nèi)重金屬含量與環(huán)境介質(zhì)(如水體、沉積物)中重金屬含量關(guān)系，發(fā)現(xiàn)痕量重金屬在河蜆體內(nèi)富集量比周圍環(huán)境介質(zhì)中含量高幾個(gè)數(shù)量級(jí)[34, 39]。雖然河蜆體內(nèi)污染物含量不能反映環(huán)境水體的真實(shí)污染水平，但是河蜆對重金屬的累積特征與環(huán)境中重金屬量分布具有很好的相關(guān)性[13, 32-33, 40]。迄今為止，體內(nèi)污染物含量監(jiān)測是河蜆在天然水體環(huán)境污染研究中唯一的實(shí)際應(yīng)用。

在生物修復(fù)應(yīng)用上，葡萄牙學(xué)者采用室內(nèi)模擬實(shí)驗(yàn)研究河蜆對酸性礦排水的生物修復(fù)效果，發(fā)現(xiàn)河蜆對水體中重金屬有較強(qiáng)的去除率，證明了河蜆用于生物修復(fù)的適用性[41]。但目前仍未發(fā)現(xiàn)有研究采用河蜆對實(shí)際重金屬污染區(qū)域進(jìn)行生物修復(fù)，而室內(nèi)模擬研究僅此一篇文獻(xiàn)報(bào)道，相關(guān)研究有待繼續(xù)開展。

在河蜆的生物毒理學(xué)研究上，河蜆在重金屬加標(biāo)介質(zhì)中的生化響應(yīng)[7, 10, 36, 42-43]、基因損傷[13-15]、解毒機(jī)制[14, 38, 44]等都有助于研究污染物對河蜆的潛在毒性影響。因?yàn)殡p殼類底棲生物在污染物的影響下早期的指標(biāo)響應(yīng)表現(xiàn)在生物標(biāo)志物層面。毒性響應(yīng)首先會(huì)在亞細(xì)胞水平表現(xiàn)出明顯響應(yīng)，隨后才會(huì)在更高生物水平顯現(xiàn)。與軟體組織內(nèi)污染物富集量測定相比，生物標(biāo)志物能夠提供更加完整的、生物學(xué)上更可靠的信息[31]。然而，受生物和非生物因素影響，生物標(biāo)志物亦無法絕對準(zhǔn)確地表征污染物生物毒性。此外，由于單生物標(biāo)志物無法充分反映生物體的健康損害程度，大量學(xué)者采用多標(biāo)志物[7-10, 43]監(jiān)測河蜆對污染物的生物毒性響應(yīng)。同時(shí)，生物標(biāo)志物與一般急性毒性實(shí)驗(yàn)評價(jià)指標(biāo)——死亡率相比，更加困難、昂貴且耗時(shí)。綜上所述，河蜆毒理學(xué)機(jī)制研究仍亟需經(jīng)濟(jì)、快捷、準(zhǔn)確的測試指標(biāo)，評估污染物對生物的健康損傷。

在生物毒性預(yù)測方面，我國臺(tái)灣學(xué)者進(jìn)行了大量的探索[45-52]。研究表明，閉殼響應(yīng)可作為一項(xiàng)生物監(jiān)測指標(biāo)研究金屬污染水體對雙殼貝類的健康影響。閉殼響應(yīng)模型技術(shù)可為將來生態(tài)預(yù)警系統(tǒng)的建立提供一個(gè)風(fēng)險(xiǎn)管理框架。

3 有機(jī)物污染水體中河蜆的生物毒性響應(yīng)研究(The biological toxicity response of Corbicula fluminea in organic contaminated water)

天然水體受人類活動(dòng)影響，接納了大量外源性有機(jī)污染物，如有機(jī)農(nóng)藥、多氯聯(lián)苯、多環(huán)芳烴等持久性有機(jī)污染物，烷基酚類，內(nèi)分泌干擾物、抗生素等多種藥物。河蜆在歐美等國被廣泛用作指示生物研究多種有機(jī)污染物的生物有效性。表3綜述了從1986到2015年間的31篇在國外期刊發(fā)表的有關(guān)河蜆對有機(jī)污染物的生物毒性響應(yīng)報(bào)道。

從研究區(qū)分布看，美國學(xué)者用河蜆做指示生物，表征有機(jī)污染物生物毒性的研究較多，其次為法國及阿根廷。我國學(xué)者在河蜆對有機(jī)污染物的生物毒性效應(yīng)研究中亦開展了大量工作[20,110-111]。測試指標(biāo)的采用及發(fā)展與重金屬污染的生物毒性研究相似。早期研究多偏重于河蜆體內(nèi)有機(jī)污染物富集量測定[30,32,88,90,95,96-98,103,107]；后期逐步發(fā)展為多指標(biāo)聯(lián)用，如行為學(xué)指標(biāo)(虹吸行為、掘穴行為、閉殼響應(yīng))、形態(tài)學(xué)指標(biāo)(組織學(xué)、組織化學(xué)、組織病理學(xué)分析)[11,93]、生化指標(biāo)(SOD、CAT、GR、GPx、GST、膽堿酯酶、AO酶、EROD等氧化還原系統(tǒng)的多種酶學(xué)指標(biāo))[2,85,87,91,94,108]、分子生物學(xué)相關(guān)方法(轉(zhuǎn)錄組測序和分析[18-19]、DNA完整性[11, 17, 85-87])等。

從污染物角度，有機(jī)污染物種類繁多，研究者多圍繞重點(diǎn)關(guān)注的持久性有機(jī)污染物、藥物、苯酚類物質(zhì)及用于船舶防污漆的三丁基錫，亦有少量學(xué)者進(jìn)行重金屬與多氯聯(lián)苯(PCB)、多環(huán)芳烴(PAH)、有機(jī)氯農(nóng)藥(OCP)復(fù)合污染的研究[54, 80]。河蜆對有機(jī)污染物生物毒性效應(yīng)研究的試驗(yàn)基質(zhì)選取情況與重金屬污染研究情況相同，多數(shù)研究采用水相加標(biāo)實(shí)驗(yàn)。對于試驗(yàn)周期，多以有機(jī)物毒性強(qiáng)弱及實(shí)驗(yàn)濃度為依據(jù)，確定不同試驗(yàn)時(shí)長。持久性有機(jī)污染物及抗生素、雌激素等藥物多采用慢性毒性實(shí)驗(yàn)[2, 11, 18-19, 54, 86-89]。

整體上，與重金屬相比，河蜆在有機(jī)污染物生物毒性效應(yīng)中的研究報(bào)道相對較少，主要集中在2個(gè)方面：(1)采用野外監(jiān)測評估實(shí)際水生環(huán)境中有機(jī)污染物污染情況；(2)有機(jī)污染物對河蜆健康影響的毒理學(xué)機(jī)理研究。河蜆體內(nèi)有機(jī)污染物含量的野外監(jiān)測分析結(jié)果表明，河蜆對疏水性有機(jī)污染物有較強(qiáng)富集能力[90-92]。河蜆體內(nèi)有機(jī)污染物累積量與水體、沉積物中含量存在顯著相關(guān)性，且污染水域?qū)油樠趸瘧?yīng)激系統(tǒng)有不良影響。室內(nèi)模擬試驗(yàn)及原位試驗(yàn)發(fā)現(xiàn)，低劑量長期暴露于有機(jī)污染物可引起行為學(xué)響應(yīng)[93]、形態(tài)學(xué)變化[11]、生化響應(yīng)[18-19, 85-87, 94]、基因損傷[17-19, 85, 87]等。由此可知，河蜆對有機(jī)污染物[19]有較強(qiáng)敏感性和生物累積能力，可以作為哨兵生物對有機(jī)物污染區(qū)域進(jìn)行生物監(jiān)測。以往研究也從細(xì)胞水平驗(yàn)證了河蜆用于環(huán)境風(fēng)險(xiǎn)評估的適用性。然而，目前沉積物毒性鑒定評估(TIE)中所采用的生物響應(yīng)指標(biāo)多為受試生物死亡率，隨著環(huán)境治理的推進(jìn)，極毒性污染逐漸減少，采用生物慢性毒性響應(yīng)指標(biāo)進(jìn)行沉積物TIE顯得尤為重要。

4 結(jié)論與展望(Conclusion and prospect)

經(jīng)過30多年的探索，國內(nèi)外在污染水體的河蜆生物毒性響應(yīng)研究上已有較為全面的發(fā)展。大量學(xué)者采用河蜆生物體內(nèi)累積、形態(tài)學(xué)及行為學(xué)觀察、生化指標(biāo)改變、代謝組學(xué)、基因完整性等生物監(jiān)測技術(shù)對氨、重金屬、有機(jī)污染物的生物毒性效應(yīng)進(jìn)行表征，認(rèn)證河蜆對實(shí)際水生環(huán)境污染狀況的評估能力，對污染水體的生物修復(fù)能力，對水體的毒性預(yù)測能力等。這些研究全面認(rèn)證了河蜆作為指示生物對于環(huán)境風(fēng)險(xiǎn)評估的適用性。

河蜆的生物毒性效應(yīng)研究多偏重于重金屬污染水體，對有機(jī)污染物研究相對較少且多局限于持久性有機(jī)污染物，對于氨、新型污染物及納米材料的研究尚處于起步階段，這些污染物對河蜆毒性影響有待進(jìn)一步開展。且多種污染物對河蜆的復(fù)合毒性研究有待進(jìn)一步加強(qiáng)。研究中多采用水相進(jìn)行模擬實(shí)驗(yàn)，對于全沉積物的研究仍需加強(qiáng)。

河蜆測試指標(biāo)從早期的生物富集量測定、行為學(xué)形態(tài)學(xué)觀察，到后期出現(xiàn)的生化指標(biāo)測定，再到分子生物學(xué)指標(biāo)測定。不同測試指標(biāo)的選取針對不同研究目的。生物富集是污染物生物毒性效應(yīng)研究的重要過程，污染物在生物體內(nèi)的富集是一個(gè)包含攝食、排泄、儲(chǔ)存、降解的動(dòng)態(tài)平衡過程；行為學(xué)及形態(tài)學(xué)觀察在污染物生物毒性響應(yīng)研究中可以提供最直觀快捷的反映；隨著生物技術(shù)的發(fā)展，污染物對蛋白質(zhì)、酶、核酸等生物大分子的毒性作用機(jī)理逐漸被關(guān)注，因此可以在不同水平進(jìn)行毒性預(yù)測，近年發(fā)展的許多生物標(biāo)志物如氧化應(yīng)激酶、基因毒性、溶酶體改變、免疫活性以及膽堿酯酶活性等被用于毒理學(xué)研究。生物富集及形態(tài)學(xué)行為學(xué)觀察可以提供直接、基礎(chǔ)的研究，而生化指標(biāo)及分子生物學(xué)指標(biāo)可以提供更多生物水平層面的毒性預(yù)測，與軟體組織內(nèi)污染物富集量測定相比，生物標(biāo)志物能夠提供更加完整的、生物學(xué)上更可靠的信息。河蜆測試指標(biāo)隨著分子生物學(xué)及相關(guān)分析檢測儀器技術(shù)的飛速發(fā)展而快速更新，且多指標(biāo)全面表征逐步代替單一指標(biāo)測試，以更全面準(zhǔn)確評估污染物對河蜆的毒性影響。然而對于不同特定毒物的特異性生物標(biāo)志物的篩選研究比較匱乏，有待進(jìn)一步研究。

目前對河蜆在沉積物毒性鑒定評估(TIE)中的應(yīng)用研究較為缺乏，尤其將河蜆的行為學(xué)及形態(tài)學(xué)變化、生化響應(yīng)、基因損傷等指標(biāo)全面結(jié)合用于沉積物毒性鑒定評估(TIE)的研究鮮有報(bào)道。而河蜆作為廣泛分布且對污染物具有較強(qiáng)富集性及敏感性的雙殼類底棲生物，具有較全面的生物監(jiān)測背景研究，對于其在沉積物毒性鑒定評估中(TIE)的應(yīng)用研究工作有待開展。
