Abstract: 

First introduced into the market in1921, leaded gasoline just passed its 100th year anniversary. Leaded gasoline was used globally in an enormous scale; however, it was also one of the first ‘environmentally unsafe’ products that eventually was forced out of the market. The rise and fall of leaded gasoline in the past century provide an ideal example to study the environmental issues overprinted with strong economic interest. The unique lessons learnt from leaded gasoline can be used to mitigate the impacts of other anthropogenic substances with global fingerprints.

Now standing in the post-leaded gasoline era, we find it important to take a moment and reflect on the impacts that leaded gasoline had on our environment, society, economy and policies. We will focus on two main questions. (a) to investigate whether the issues of environmental lead pollution have been resolved following the phasing out of leaded gasoline; (b) to draw insights from the lessons learnt from leaded gasoline world which can provide a viewpoint that can be adapted to achieve equitable and sustainable management of other sources of lead exposure and indeed of other new chemicals introduced into the environment.

摘要：

含铅汽油自1921年首次亮相市场，如今已经走过了一百年的历史。这种汽油曾被广泛使用，但也是首批被认定为对环境有害的产品之一，最终不得不退出历史舞台。含铅汽油的兴衰历程，为我们研究那些与经济利益紧密相连的环境问题提供了绝佳的案例。从这段历史中汲取的教训，有助于我们应对其他全球性污染物的影响。

站在含铅汽油时代的尾声，我们认为有必要回顾一下它对我们的环境、社会、经济和政策产生了哪些影响。我们将主要探讨两个问题：(a) 评估在含铅汽油被淘汰后，环境铅污染问题是否已经得到有效解决；(b) 从含铅汽油的历史中总结经验，以便为其他铅暴露源，甚至是新进入环境的化学物质，提供一种公平和可持续的管理视角

Biography：

Dr. Mengli Chen is a research fellow at Tropical Marine Science Institute, National University of Singapore. She is an expert in the area of chemical oceanography, and particularly interested in the marine environment changes through time. The ongoing global warming is expected to alter the marine environment in the tropical surface ocean, hence affecting many marine species that human depend for daily subsistence.

She used natural archives like corals; investigating their chemical compositions and isotopes; and reconstructing the environment in which they lived in. Through paleoenvironmental reconstruction, her researches aim to understand the processes in transport/transform material through the ocean. The knowledge on chemical cycling will subsequently feed into strategies, practices in solving take real-world issues.

嘉宾介绍：

陈梦立博士在新加坡国立大学的热带海洋科学研究所担任研究员。她专攻化学海洋学，尤其对海洋环境随时间的演变感兴趣。随着全球变暖的持续，预计热带表层海洋的环境将会发生变化，这将影响到许多人类赖以生存的海洋生物。

她通过研究珊瑚等存储了过去环境变化的自然介质，分析它们的化学成分和同位素，重建了珊瑚生长时的生活环境。她的研究通过古环境重建，旨在理解海洋中物质的传输和转化过程。这些关于化学物质循环的知识，将有助于制定解决现实世界问题的策略和实践。

Look forward to seeing you!
