2017年研究院团队成员苏芳莉教授等在期刊“Physics and Chemistry of the Earth”上发表题目为“Influence of paper mill wastewater on reed chlorophyll content and biomass”的论文，文章主要关注在实验条件下，常见的湿地植物芦苇在接触造纸厂废水后的生长状况。通过将芦苇种植在含有不同浓度的造纸厂废水的培养液中，来模拟实际环境中的情况。研究发现暴露在造纸厂废水中的芦苇叶绿素含量显著下降，表明废水中可能含有某些化学物质，影响了芦苇的光合作用能力。此外，研究还观察了芦苇的生物量，发现与未暴露于废水的芦苇相比，接触废水的芦苇生物量减少，进一步证实了造纸厂废水对芦苇生长的不利影响。因此有效的废水处理和环境保护措施对于维护湿地生态系统的健康至关重要，本研究为我们更好地了解废水对植物影响提供了重要的科学依据。

     Abstract Studies on the influence of paper mill wastewater, which affects photosynthesis, on reed chlorophyll and bio- mass can provide a theoretical basis for the ecological restoration of wetland plants. The influence of different concentrations of wastewater (chemical oxygen demands (COD) of 300, 175 and 50 mg•L⁻¹) and different ir- rigation times (germination, blade-expansion, rapid-growth, heading and maturity stages) on the contents of chlorophyll a, chlorophyll b, total chlorophyll and chlorophyll a/b in reeds were tested in experimental pools that simulated the wetland ecosystem of the Liaoning Shuangtai estuary. The contents of chlorophyll a, chlor-ophyll b, total chlorophyll and chlorophyll a/b all increased significantly with increasing concentrations of wastewater, and their contents all differed significantly from each other. The contents of chlorophyll a, chlor- ophyll b and total chlorophyll were maximal when irrigated at the beginning of all growth stages with COD of 300 mg•L⁻¹(C1O) at 2.253, 0.458 and 2.711 mg•g⁻¹ fresh weight (FW), respectively, with irrigation at the rapid- growth stage and were minimal in the control plants at 0.142, 0.068 and 0.210 mg•g⁻¹ FW, respectively, with irrigation at maturity. Chlorophyll a/b was maximal at C1O at 5.753 with irrigation at germination stage and was minimal in the control plants at 2.113 with irrigation at maturity. Reed biomass was maximal at C1O at 3.26 kg, which was 2.76 times higher than the control. Reed biomass was positively correlated with the content of chlorophyll and with COD in the wastewater. Paper mill wastewater generally increased the content of chlorophyll and the net photosynthesis rate and enhanced the growth of reeds.
