Abstract:With the development of chemical industry and the establishment of chemical industry parks, Chemical safety risks are increasingly exposed to the public. What media are the public′s chemical risks more vulnerable to? In this paper, a stratified random sampling method was used to conduct a questionnaire survey on residents around Shanghai Chemical Industry Park. Based on the framework of social amplification of risk, linear regression and quantile regression were used to explore the impact of media use and environmental knowledge on risk perception of residents around Shanghai Chemical Industry Park. The study showed that traditional media, new media and interpersonal media all had significant positive effects on risk perception. Traditional media had greater impact on low-risk perception, new media have greater impact on high-risk perception, and interpersonal media had an impact on all risk perception of the population. In addition, environmental knowledge weakened the public′s perception of chemical risks and the impact of media use on chemical risks. Finally, some countermeasures and suggestions were put forward, such as strengthening the supervision of network public opinion and popularizing scientific and chemical knowledge to the public.
