Abstract

Modeling and predicting heavy metal uptake by plants using organic amendments helps reduce metal concentrations in contaminated soils. This study examined the effects of 1% and 2% (W/W) biochar and urban waste compost on the growth and cadmium (Cd) and lead (Pb) uptake by Bromus tomentellus in contaminated soil. The highest plant height (34.0 cm) and biomass (30.0 g) occurred with 2% biochar, compared to 16.0 cm and 9.0 g in control. For Pb, the maximum bioconcentration factor (BCF) was 2.25 with 1% compost, and the highest translocation factor (TF) was 1.4 with 2% biochar. For Cd, both max BCF (3.40) and TF (1.4) were seen at 1% biochar. Metal uptake and transfer significantly correlated with biomass and soil factors such as fertility (N, P, and K), pH, sodium adsorption ratio (SAR), and organic matter (OM) (Mantel test: p = 0.1, r = 0.4). The Group Method of Data Handling (GMDH) model, with high accuracy (R² = 0.998), showed compost caused an initial rise then decline in Cd uptake, while biochar had the opposite effect. Pb uptake increased with compost up to 1.052%, peaking at 763.7 ppm, then decreased. The GMDH model can optimize biochar or compost levels to enhance metal uptake by plants in polluted soils.

添加生物炭和城市垃圾堆肥有机改进剂影响下毛毛帚对铅和镉吸收的群体数据处理方法（GMDH）模型。

利用有机改进剂模拟和预测植物对重金属的吸收有助于降低污染土壤中的金属浓度。研究了1%和2% （W/W）的生物炭和城市垃圾堆肥对污染土壤中毛毛Bromus tomentellus生长和镉、铅吸收的影响。2%生物炭处理的株高（34.0 cm）和生物量（30.0 g）最高，而对照为16.0 cm和9.0 g。在1%堆肥条件下，Pb的最大生物富集因子（BCF）为2.25；在2%生物炭条件下，Pb的最大转运因子（TF）为1.4。对于Cd， 1%生物炭的最大BCF（3.40）和TF（1.4）均达到最大值。金属吸收和转移与生物量和肥力（N、P、K）、pH、钠吸附比（SAR）、有机质（OM）等土壤因子显著相关（Mantel检验：P = 0.1, r = 0.4）。群体数据处理方法（GMDH）模型具有较高的精度（R2 = 0.998），表明堆肥对Cd的吸收先上升后下降，而生物炭则相反。铅吸收量随堆肥的增加而增加，达到1.052%，峰值为763.7 ppm，随后下降。GMDH模型可以优化生物炭或堆肥水平，以提高污染土壤中植物对金属的吸收。

期刊介绍： The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
