The surface soil on sewage outfall and effluent of farmer household septic tank were collected in situ from the typical region of plain river network areas in Taihu Lake Basin, and the typical rainfall (summer 30 mm . times-1, winter 5 mm times -1), temperature (summer 27 degrees C, winter 5 degrees C ) condition and pollutant load were artificial simulated by indoor simulation soil column experiments for estimating nitrogen abatement rate of rural sewage treated by the outfall soil and exploring the abatement rule in different seasons and weather process (7 days before the rain, 3 rainy days, 7 days after the rain). Results showed that: there was the significant difference (P <0.

Article Synopsis
- Hydroponic experiments revealed that phenanthrene negatively impacts wheat growth, with an 18.01% inhibition rate, which worsens to 24.38% in the presence of dissolved organic matter (DOM) from pig manure.
- Wheat can absorb and accumulate phenanthrene, and this process is enhanced by DOM, resulting in a significant increase in the root bioconcentration factor from 2.84 L x kg(-1) to 37.63 L x kg(-1).
- The study suggests that a H+ -phenanthrene cotransport system is involved in the uptake process, and DOM also promotes the transfer of phenanthrene from roots to other plant parts while positively influencing the uptake of inorganic nutrients
Article Synopsis
- Researchers studied how dissolved organic matter (DOM) affects the eco-toxicity of phenanthrene (phe) in soil, finding that DOM acts as a surfactant.
- The research determined that phe inhibits wheat root growth, with a sensitivity range of 0 to 200 mg/kg and a median inhibition concentration (IC50) also at 200 mg/kg.
- The presence of DOM alleviated the eco-toxicity of phe, especially at high concentrations, indicating that DOM can help reduce the harmful effects of phe on soil health and moisture levels.
