By analyzing and interpreting the results, we identified the top3 concerns and top3 suggestions relatively. The top3 concerns are the risk of bio-leakage, the stability of monitoring equipment and the effect on ecological balance, and the top3 suggestions are paying more attention to biosafety, responding to public concerns properly, and learning from foreign successful experiences. From the results we got, we can see, thought synthetic biology is regarded as a growing field, the majority of citizens without professional background are still confused about its principles and mechanisms. Regarding the relationship between health and environment, nearly all respondents think the two aspects are related, which is consistent with the project background. The 66.22% of all respondents who think it risky to put engineered bacteria into environment actually present a common concern, which cannot be solved by solely improving the project, but we should also find ways to explain our designs in a more accessible way for the public to comprehend. As for the future development of bioremediation in China, most respondents think the prospect is quite positive, which also greatly encourages us to continue implementing synthetic biology for solving practical problems. From our perspective, the fast-developing technology is always a double-edge sword, which should be handled carefully to do more good to our society, and taking public opinions into consideration is a useful method for us to view our projects from different angles and keep improving.
