课程名称：化学与健康 课程概述：本课程探讨了环境和我们身体中的化学物质，以及它们如何影响我们的健康。课程内容涵盖了与化学物质相关的政策和实践，重点讨论了这些物质是如何进入我们身体的（暴露），它们在体内的作用（毒理学），我们如何测量它们（生物监测）及其对健康的影响。大多数例子来源于美国。 课程大纲： 第一周：欢迎与介绍 本周将通过同伴评估开始，了解学员对即将讨论主题的初步理解。接下来，课程将简要概述化学物质及其暴露方式，并介绍化学品的生产和监管。最后有一个有趣的作业：观看一段八分钟的视频并进行讨论。 第二周：毒理学：化学物质在我们身体中做什么？ 在理解了化学物质及其暴露方式后，课程将深入探讨化学物质对健康的影响，着重讲解毒理学。学员将评估和评分至少四位同学的作品，并参加涵盖第一和第二周内容的十道选择题测验。 第三周：生物监测：我们如何测量身体中的化学物质及其原因？ 通过观看视频和新闻报道，学员将分享对这些材料的反应，并聆听CDC科学家关于美国国家生物监测计划的讲解，关注社区与政府的关系。本周的内容相对轻松。 第四周：化学物质的健康影响：我们如何评估化学物质对健康的影响？ 本周将讨论科学家如何评估化学物质对健康的影响，并邀请环境与职业医学及流行病学领域的医生进行讲解。同时，了解政策制定者如何利用现有知识评估风险和推动政策。课程结束时将进行一次测验。 第五周：化学政策：我们该如何应对化学物质与健康问题？ 本周聚焦于社会如何通过政策应对化学物质对健康的影响。学员将了解一个非营利组织如何推动相关法律和法规的变更，并探讨这些变更对健康和环境的历史影响。课程后有另一次同伴评估，评估学员对化学物质与健康复杂关系的理解变化。 第六周：案例研究 本周将讨论如何将这些信息整合起来，涵盖从自然界中的化学物质到大型生产，再到暴露、健康影响和政策的实际案例。学员将了解烟草、受污染的食物、饮用水、纳米技术和工人健康等主题，并进行同伴评估。课程最后将总结并提出对化学与健康进一步学习或行动的建议。 希望通过此课程，学员能更深入理解化学物质与健康之间的关系，从而积极参与相关问题的讨论与行动。
Name:Week 1: Welcome & Introduction
Description:Start off this week with the peer assessment (we know, we know. . .how can we have an assessment before the course even starts, right?). We simply hope to gauge your initial understanding of the topics that we’ll cover (so grade easy). Then we get into a quick overview of the course, a discussion of chemicals & how we are exposed (in three parts) and an introduction to chemical production & regulation. The module ends with a fun homework assignment: watch an eight-minute video and discuss amongst yourselves (and with us too).
Name:Week 2 - Toxicology: What do chemicals do in our bodies?
Description:Now that you have a sense of what a chemical is, and how we are exposed to them, we dive into the science of how chemicals impact our health, starting with toxicology. But before you dive into the study of poisons, please review, evaluate, and grade at least four of your classmates' submissions from last week. After you listen to the lectures by Professor Trush, take the ten-question/multiple-choice quiz that covers weeks 1 & 2. Feel free to go back and use the lectures to help you answer the questions.
Name:Week 3 - Biomonitoring: How do we measure these chemicals in our bodies and why?
Description:Start by watching a two-minute video and a five-minute news report. Post your reactions not only to the video and audio files, but also to your peers’ thoughts! Next you’ll hear from a CDC scientist about the US’ National Biomonitoring Program, then you’ll hear how that program translates to the local level. Be sure to keep in mind the relationship of communities to their government! This week is pretty light – so enjoy!
Name:Week 4 - Health effects of chemicals: How do we figure out how chemicals affect our health?
Description:Finally we get to one of the main questions presented in this course - how do scientists assess the impact of chemicals on our health? You’ll hear from a physician who specializes in environmental & occupational medicine and epidemiology. Then you’ll hear how policymakers use the knowledge that we do have (about chemicals & health) to assess risk and drive policy. Once you’ve viewed the two lectures, another ten-question/multiple-choice quiz will assess how much information you absorbed from weeks 3 and 4. Feel free to go back and use the lectures to help you answer the questions.
Name:Week 5 - Chemicals Policy: What do we do about chemicals & health?
Description:So far we’ve covered: how chemicals get into our bodies and how we measure them, what our bodies do with them and what they do to our bodies, and how that ultimately impacts our health. Now we turn to policy and how society addresses the impact of chemicals on health. We will hear from a non-profit group that works to change policies such as laws & regulations related to this area. Then we’ll hear how such changes have impacted our health and environment historically, looking specifically at air quality regulation in the US. After you view the lectures in Module 5, there is a second peer-reviewed writing assessment that aims to gauge your shift in understanding the complex relationship between chemicals and health (again grade each other generously).
Name:Week 6: Case Studies
Description:At this point you may be wondering: so how do all these pieces fit together? From chemicals in our natural world to production on a large scale, through exposure to health effects and policy . . . this module provides real world examples of how the general public, scientists, industry, governments and non-profit groups come together to effect change. Specifically, we’ll hear about tobacco, contaminated food, drinking water, nanotechnology & worker health. At some point this week (either before, after or in-between listening to the case studies), you’ll need to review, evaluate, and grade at least four of your classmates' submissions from last week. The final lecture offers a summary & conclusion, hopefully providing ideas for next steps for those of you interested in learning or doing more related to chemicals & health. Please let us know how we did and how we can improve!
This course covers chemicals in our environment and in our bodies and how they impact our health. It addresses policies and practices related to chemicals, particularly related to how they get into our bodies (exposures), what they do when they get there (toxicology), how we measure them (biomonitoring) and their impact on our health. Most examples are drawn from the US.
