Air pollution is one of the leading causes of respiratory viral infection. Particulate matter (PM2.5) is an example of air pollution that incorporates virus and bacteria small enough to float in the atmosphere. Which with its involvement within the respiratory system causes multiple cases that originated from simplicity to more complicated situation. In this review, different micro-material / gaseous were discussed. The function of microbiome located in the respiratory tract and how immune system would react in the presence of air pollution to respiratory viral infection

Faced with increasingly serious soil pollution problems, China has passed the Chinese Soil Pollution Prevention and Control Law (hereinafter referred to as the Law on the Prevention and Control of Soil Pollution) and established a series of soil pollution remediation systems. However, there are still some shortcomings in the current legal system for soil pollution remediation, which cannot fully solve the problems faced in soil remediation activities. The research focuses on the legal system for soil pollution remediation. This study analyzes the development process of relevant systems, focusing on the analysis of the Soil Pollution Prevention and Control Law, including the basic content and process of soil pollution prevention and control work. On this basis, this study summarizes the legal structure and practice of soil pollution control in China and analyzes the problems existing in the implementation of China’s soil pollution remediation legal system, such as imperfect remediation standards and insufficient public participation. Then, the relevant policies of EU countries are summarized and analyzed. Combined with the actual situation of China, suggestions are put forward to improve the legal system of soil pollution remediation in China and strengthen soil remediation.
