Acknowledgement

We deeply appreciate the effort of Prof. He, primary PI, for supervising our lab techniques and aiding us in project design. We also want to thank Prof. Ma, our secondary PI, for providing valuable advice. Additionally, we extend our gratitude to our instructors Prof. Wang and Prof. Xu for their tremendous assistance in the biological experiment portion. Their dedication to helping us select ideas from brainstorming sessions and providing project support is greatly valued.

We also extend our gratitude to Prof. Kong from the SCHOOL OF ENVIRONMENT SCIENCE AND ENGINEERING, SJTU for providing us with lead chloride and lead sulfate reagents for our experiments. We also appreciate Prof. Zhang, Prof. Deng, and Prof. Ma from the SHANGHAI AGRICULTURAL PRODUCT QUALITY AND SAFETY TESTING CENTER for assisting us with the detection of lead ion concentration in the solution. We are also very grateful to Prof. Qian and Prof. Zhao from the SHANGHAI ACADEMY OF ENVIRONMENTAL SCIENCES (SAES) for providing valuable guidance on the social context and expertise for our project.

We are fortunate enough to have advisors, experts and senior undergraduate students who offered vital advice and contribution in the making of this project.

We also want to express our special thanks to Prof. Zhang and Prof. Qin at the NATIONAL EXPERIMENTAL TEACHING CENTER FOR LIFE SCIENCES AND BIOTECHNOLOGY for providing us with the lab facilities and a wide array of experimental equipment.

We would also like to express our deep appreciation for the teams that collaborated with us on project ideas, including SJTU-software, NYCU-Formosa, NTHU-Taiwan, McGill, and many others at the Conference of China iGEMer Community (CCiC). We are particularly grateful to the members of the Heavy Metal Alliance: XJTLU-CHINA, iGEM IIT Delhi, and 48C (EPFL), who joined us in our collective efforts to address heavy metal pollution.

We would also like to express our gratitude to YUNNAN YUHU JUNIOR HIGH SCHOOL and YUMIN COUNTY No.1 MIDDLE SCHOOL for providing us with the opportunity to engage in educational outreach and share knowledge about biology and synthetic biology.

We would also like to express our gratitude to Shanghai RundaRongjia Biological Technology Co., Ltd for their sponsorship.

Finally, we want to extend our appreciation to every dedicated iGEMer on our team!
