Abstract

Abstract

To explore the effects of crude oil contamination on the particle size and stability of soil aggregates, taking the simulated polluted soil as the research object, parameters such as particle size of soil mechanically stable aggregates, particle size of water-stable aggregates and crude oil concentration of aggregates under the condition of different crude oil content (2%, 5%, 10%) and different polluting duration (2 d, 15 d, 30 d) were studied. The results showed that: the proportions of mechanically stable aggregates and water-stable aggregates with a particle size of 2 mm above were increased by crude oil, and the proportions of mechanically stable aggregates and water-stable aggregates with a particle size of less than 0.25 mm were reduced. With the polluting duration prolonged, the proportion of aggregates with a particle size of 2 mm above increased significantly, and the proportion of aggregates with a particle size of 0.25mm below decreased significantly. The crude oil concentration of aggregates with the same particle size increased with the increase of total oil content of the soil. The distribution of crude oil in aggregates with different particle sizes decreased in the order of 2 mm above >0.25 to 2 mm>0.25 mm below. The distribution of crude oil in aggregates with a particle size of 2 mm above accounted for more than 60% of the total crude oil. Crude oil changed the particle sizes of soil aggregates, increased the stability of aggregates and promoted the formation of large aggregates with a particle size of 2 mm above. Crude oil was mainly distributed in large aggregates.
