摘要 在实验室条件下，研究了大气CO2浓度升高对最低等多细胞动物海绵过滤功能影响。在模拟大气CO2浓度升高的生态系统中，考察了CO2浓度为387、500、750、1000 mg/L的环境下，繁茂膜海绵Hymeniacidon perlevis阻留灭菌海水中总有机碳(TOC)的能力。结果表明：在模拟CO2浓度为387、500、750、1000 mg/L的条件下，繁茂膜海绵在16 h内清除海水中TOC的效率分别为55.8%、67.6%、50.0%和15.4%,在24 h对 TOC 的平均阻留率分别为(1.90±0.20)、(2.13±0.06)、(1.69±0.08)、(0.43±0.11) mg/(h·g海绵)，平均清除率分别为(0.025±0.002)、(0.033±0.001)、(0.019±0.001)、(0.004±0.001)mL/(h·g海绵)，由此可见，大气CO2浓度从约387 mg/L升高至500 mg/L时，促进了繁茂膜海绵阻留海水中TOC的能力，当浓度升高至750 mg/L时，抑制了繁茂膜海绵阻留TOC的能力，当浓度进一步升高至1000 mg/L时，导致繁茂膜海绵几乎丧失了阻留海水中TOC的能力。本研究结果可为大气CO2浓度升高对潮间带海绵过滤功能影响及其由此可能导致的近岸海域生态问题提供了参考。

Abstract: The effects of elevated atmospheric CO2 concentration on removal of total organic carbon (TOC) in sterilized natural seawater (SNSW) by sponge Hymeniacidon perlevis were investigated at CO2 concentration of 387, 500, 750 and 1000 mg/L in a simulated ecological system. The TOC removal was shown to be 55.8% at CO2 concentration of 387 mg/L, 67.6% at CO2 concentration of 500 mg/L, 50.0% at CO2 concentration of 750 mg/L and 15.4% at CO2 concentration of 1000 mg/L at the initial TOC concentrations for 16 h. The average retention rate of TOC within 24 h was (1.90±0.20)mg/(h·g fresh sponge) at CO2 concentration of 387 mg/L, (2.13±0.06)mg/(h·g fresh sponge) at CO2 concentration of 500 mg/L, (1.69±0.08)mg/(h·g fresh sponge) at CO2 concentration of 750 mg/L, and (0.43±0.11)mg/(h·g fresh sponge) at CO2 concentration of 1000 mg/L. The average clearance rate of TOC within 24 h by the sponge was (0.025±0.002)mg/(h·g fresh sponge) at CO2 concentration of 387 mg/L, (0.033±0.001)mg/(h·g fresh sponge) at CO2 concentration of 500 mg/L, and (0.019±0.001)mg/(h·g fresh sponge) at CO2 concentration of 750 mg/L and (0.004±0.001)mg/(h·g fresh sponge) at CO2 concentration of 1000 mg/L. It was found that rising atmospheric CO2 concentration from 387 mg/L to 500 mg/L led to promote the retention rate of TOC. However, the rising atmospheric CO2 concentration to 750 mg/L resulted in suppression of the removal ability of TOC in SNSW ability, even no removal ability of TOC in SNSW ability, was observed at CO2 concentration of 1000 mg/L. The findings provide a few cognition of influence of rising atmospheric CO2 levels on filtering capacity of intertidal sponge, thus leading to ecological issues in coastal waters.
