As industrial production increases worldwide, so does the demand for fuels. The transport of fuels from the point of production to the end user poses a risk of environmental pollution, both during transport and during combustion in internal combustion engines. The soil is a part of the environment which is particularly sensitive to contamination by petroleum substances. For this reason, research has been carried out into the possibility of reducing the impact of petrol on the content of heavy metals in the soil using various materials, both mineral (bentonite, calcium oxide) and organic (compost). These played an important role in the in situ remediation of contaminated soils. Petrol contamination increased the content of some heavy metals (Pb, Cd, or Ni), while it decreased the content of other metals (Cr, Zn, Co, and Cu) in the soil. The materials used in this study significantly altered the levels of heavy metals in the soil. The strength of the effect varied and the direction of the effect depended on the element. Bentonite was the most effective, while calcium oxide and especially compost were less effective. The most beneficial (limiting) effect of calcium oxide was shown on the soil content of cadmium, cobalt, and chromium, while the bentonite effects were on the content of chromium. The application of the abovementioned materials seems to be effective in reducing low level soil contamination by petrol.
随着全球工业生产的增加，对燃料的需求也在增加。燃料从生产点运输到最终用户的过程中，在运输过程以及在内燃机燃烧过程中都存在环境污染风险。土壤是环境的一部分，对石油物质污染特别敏感。因此，人们开展了研究，探讨使用各种材料（包括矿物材料（膨润土、氧化钙）和有机材料（堆肥））来降低汽油对土壤中重金属含量影响的可能性。这些材料在受污染土壤的原位修复中发挥了重要作用。汽油污染增加了土壤中某些重金属（铅、镉或镍）的含量，同时降低了其他金属（铬、锌、钴和铜）的含量。本研究中使用的材料显著改变了土壤中重金属的含量。影响的强度各不相同，影响的方向取决于元素。膨润土最有效，而氧化钙尤其是堆肥效果较差。氧化钙对土壤中镉、钴和铬的含量显示出最有益（限制）的影响，而膨润土对铬的含量有影响。上述材料的应用似乎对减少土壤中汽油的低水平污染有效。
