摘要：The contamination of soil by hydrocarbons from waste of petrol pump is an important subject to board. The objective of this work was to study the effect of different concentrations of gas oil, naphtha and burned oil, and of mud and landfarming upon Trichocereus terscheckii survival. The bioassay was carried out in laboratory following a complete randomized design with four replicates for treatment, with constant temperature and light. There were nine plantules (three months years old) for treatment. Survival of plantules was lower at both gas oil and naphtha concentrations examined, and higher in burned oil and landfarming
