摘要：Oil production often leads to territory contamination by reservoir water. Often during the recultivation of oil fields land and water bodies oil pollution is considered more important than negative impacts of reservoir water. Meanwhile during spills high salty reservoir oil waters have a greater negative impact on the environment than oil sometimes. In this regard the important task is to determine the extent of their toxic effects for the biological objects. This article provides a comparative assessment of the toxicity of the reservoir waters of the deposit and model waters prepared in accordance to the chemical composition of the produced water. The test-objects were the Lepidium sativum seeds of two species - "Zabava" and "Krupnolistovoi". To determine the toxicity of the environment such parameters as seed germination, length and average dry weight of seedlings were considered. The conducted experiments show good responsiveness of both species of Lepidium sativum and usability to the toxicity assess of produced oil waters. The obtained data testify to the acute toxicity of the produced water. The study results analysis shows the need to take into account the toxic properties of the reservoir waters that can get into the water and soil with oil during the development of water resources and land restore measures.
