【摘要】：為全面了解海洋生物體內(nèi)稀土元素的分配模式,采用ICP-MS測(cè)定山東東部近海海域主要海洋生物體內(nèi)稀土元素含量,濃度范圍為30.17μg·kg~(-1)~807.33μg·kg~(-1),其中藍(lán)點(diǎn)馬鮫(Scomberomorus niphonius)牙鲆(Paralichthys olivaceus)刀額新對(duì)蝦(Metapenaeus ensis)疣荔枝螺(Thais clavigera)刺參(Apostichopus japonicus)貽貝(Mytilidae)海帶(Laminaria japonica);7種海產(chǎn)品均明顯富集輕稀土,輕重稀土的比值在3.6~51.7之間,底棲魚(yú)類(lèi)對(duì)輕稀土的富集性最大;7種海洋生物稀土含量經(jīng)北美頁(yè)巖標(biāo)準(zhǔn)化后,基本都呈近似平坦而略有輕稀土富集的分布趨勢(shì),即海洋生物對(duì)稀土元素的利用遵從豐度規(guī)律;南北方海域水體中稀土濃度相差不大,平均值為0.75μg·kg~(-1)~15.06μg·kg~(-1),水體pH為7.54~8.14,同一海域,藻體中稀土元素含量與pH呈負(fù)相關(guān)。
[Abstract]:In order to fully understand the distribution model of rare earth elements in marine organisms, ICP-MS was used to determine the contents of rare earth elements in the main marine organisms in the eastern coastal waters of Shandong Province. The concentration range is 30.17 渭 g 路kg~(-1)~807.33 渭 g 路kg ~ (-1), in which Scomberomorus niphonius (Paralichthys olivaceusus)) Metapenaeus olivaceus.) (Thais clavigera) (Apostichopus japonicus)) Laminaria japonica (7 species of marine products are obviously enriched in light rare earths, the ratio of light and heavy rare earths is between 3.66 and 51.7. The enrichment of light rare earth elements in benthic fish is the greatest. After the standardization of North American shale, the rare earth contents of seven species of marine life are almost flat and slightly enriched, that is, the utilization of rare earth elements by marine life obeys the law of abundance. The concentrations of rare earth elements in the waters of the north and south of China were similar, the average value was 0.75 渭 g 路kg~(-1)~15.06 渭 g 路kg ~ (-1) 路kg ~ (-1), and the pH value of the water was 7.54 ~ 8.14. In the same sea area, the content of rare earth elements in algae was negatively correlated with pH.
