In the past five decades,global plastic production has increased at an average yearly growth rate of 8.4%,which is significantly higher than that of other basic materials such as cement,steel,and aluminum[1,2].Moreover,the amount of global plastic waste more than doubled between 2000 and 2019,reaching an annual production of 353 million tons(Mt)[3].It was further estimated that plastic accounted for approximately 12%of municipal waste in 2016 globally[4].

The widespread occurrence of perfluorooctane sulfonate (PFOS) and the mass production and application of graphene oxide (GO) lead to their inevitable release and interaction in the environment, which may enhance associated toxic impacts on aquatic organisms. This study elucidates the induction of apoptosis by 60-day chronic single and mixture exposures to environmentally relevant levels of PFOS (0.5 μg/L and 5 μg/L) and GO (1 mg/L) in adult marine medaka Oryzias melastigma.

The role of plant uptake in total phosphorous and total nitrogen removal in vegetated bioretention cells using vetiver and cattail

引用

Chemosphere 2024年 364卷 143276页

作者： Narayanasamydamodaran, Sanjena Kumar, Nawnit Zuo, Jian'e State Key Joint Laboratory of Environmental Simulation and Pollution Control School of Environment Tsinghua University Beijing100084 China State Key Laboratory of Hydroscience and Hydraulic Engineering Tsinghua University Beijing China Institute of Environment and Ecology Tsinghua Shenzhen International Graduate School Shenzhen518055 China

Bioretention cells have emerged as a prominent strategy for mitigating pollutant loads within urban stormwater runoff. This study delves into the role of plant uptake in the simultaneous removal of nitrogen and phosphorus compounds within these systems. Three bioretention cells—CP, P1, and P2—were constructed using local soil, C33 sand, and gravel. CP served as the unvegetated control, while P1 and P2 were vegetated with vetiver and cattail, respectively. The removal efficiencies of NO₃⁻-N, NH₃⁻-N, NO₂⁻-N, TN, TP, and COD from rainwater were evaluated under saturated and unsaturated conditions. The unvegetated control reactor (CP) achieved TN and TP removal rates of 40.44% and 82.52%, respectively. Reactor P1 (vetiver) demonstrated TN and TP removal rates of 62.92% and 97.19%, respectively. Reactor P2 (cattail) showed TN and TP removal rates of 49.71% and 87.78%, respectively. With the introduction of a saturation zone, TN removal efficiencies increased to 51.69%, 89.22%, and 79.91% for CP, P1, and P2, respectively. However, TP removal efficiencies decreased to 74.81%, 95.04%, and 84.58% for CP, P1, and P2, respectively. Plant tissue uptake tests indicated that vetiver could retain 5 times more TN and twice as much TP compared to cattail. This enhanced performance is attributed to vetiver's high photosynthetic potential as a C4 plant, resilience to varying environmental and nutrient conditions, extensive root network, secretion of oil sesquiterpenes from its root cortex, and the presence of arbuscular mycorrhizal fungi, which secrete glomalin, a substance that promotes water retention and nutrient uptake. Findings from this study indicate that the efficacy of traditional bioretention cells can be augmented through the strategic selection and integration of locally adapted plant species, coupled with the incorporation of saturation zones, to enhance pollutant removal capabilities and resilience to drought conditions. © 2024
