Introducing smart supply chains is one of the basic and important steps in the field of oil, gas and petrochemicals in the current sanctions situation. On the other hand, due to the high complexity of oil and gas supply chain management and the very high geographical dispersion of this field and advanced features such as data-oriented management, information sharing, maintaining confidentiality and privacy of data, cyber security, transparency , smart contracts, tracking and tracing capabilities, and network reliability that promote agility in the entire supply chain are of particular importance. The main purpose of this article is to study the effects, the way of implementation and the effects of establishing the smart contracts system on the performance of the oil, gas and petrochemical fields. Therefore, it has been tried to deal with the dimensions, angles and effects of this field with a systematic review. The research method of the previous article is prescriptive and the author, by conducting library research on the policy challenges of concluding smart contracts in the field of oil, gas and petrochemical industries, tried to prescribe the implementation of the mechanisms of conclusion of one of the newest electronic tools. applied in this field. The findings show that the use of smart contracts has reduced the current administrative bureaucracies, improved the speed, accuracy and efficiency of the entire supply chain of the oil and gas field and can play an effective and significant role in managing the complex activities of this field. . Also, in line with the establishment of these systems, there are some technical, security and legal restrictions that should be examined more carefully and other aspects of these contracts in accordance with the constitutional rights of our country should be checked and examined more. be placed.

Nowadays, Water contamination is one of the major problems and challenges in the world that can be considered as one of the main factors of diseases and mortalities in the world. Both surface and ground waters are exposed to the different contaminants. With regard to the nature and source of their entrance (man-made or naturally occurring), various classifications have been considered for contaminants. The main organic contaminants of water are agricultural, chemical, oil, and food contaminants. Each of these four groups has sub-criteria. In this research, water contaminants in oil and petrochemical industries have been identified and ranked through using Principle Component Analysis (PCA) as well as Analytical Network Process (ANP) methods. Results of Principle Component Analysis method reveal the fact that lead, nitrate and sodium contaminations have been ranked at the highest level from the environment experts’ point of views regarding water contamination. Furthermore, results of ANP show that agricultural and oil contaminants with the weights of 0.321 and 0.152 ranked first and fourth respectively. Finally, I hope that the relevant organizations can take effective steps to prevent environmental degradation which is created by oil and chemical industries contaminants.
