The total petroleum hydrocarbon (TPH) was observed after 120 days phytoremediation at five depths with different petroleum contamination grads, namely 0∼−20cm, −20∼−40cm, −40∼−60cm, −60∼−80cm, and −80∼−90cm. The change of TPH with increasing soil depth for different agrotype was analyzed. As demonstrated in this work, the TPH for three kinds of agrotype was reduced gradually with increasing depth...
The impact of petroleum on soil catalase activity was presented. The loess in Gaoling, silt in campus and loess in Northern Shaanxi were used in the experiment. The Trioflium repens was chosen as the remediation plant. The soil samples were amended with petroleum in the concentration range from 0 to 10000mg/kg, whereas the samples without the plants as controls. Catalase activity was assayed by one...
Geodatabase development for coastal studies conducted by the Naval Research Laboratory (NRL) is essential to support the exploitation of hyperspectral imagery (HSI). NRL has found that the remote sensing and mapping science community benefits from coastal classifications that group coastal types based on similar features. Selected features in project geodatabases relate to significant biological and...
The study was aimed at investigating the local plants along two sides of Dagu River to achieve guidance on the harness, remediation or management of Dagu River. For this, the herbage plant species and their covering area, heavy metal contents in the plants, and the correlation analysis between metals in local plants and in nearby sediments were investigated. Results indicate that the dominant plants...
