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.

Week 2 - Toxicology: What do chemicals do in our bodies?
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.

Week 4 - Health effects of chemicals: How do we figure out how chemicals affect our health?
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.

Excellent way of presenting the material. Simple to understand.\n\nBut one suggestion: videos are little lengthier, you may plz look into making shorter videos as tge content is in-depth

Overall ,it is very excellent course about health and chemicals , too much of knowledge about environment and chemicals and how they affects the human health and all other after effects .
由 TB 提供2020年6月10日
Well structured, easy to follow, knowledge gained allowed for quizzes and assignments to be answered fully. I feel like I've come away with a good foundation for toxicology.

It's an eyes opening and enriching course. So many important issues and their solutions were discussed in detail. Thank you Johns Hopkins University and Coursera.
常見問題
我什么时候能够访问课程视频和作业？
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
我购买证书后会得到什么？
您购买证书后，将有权访问所有课程材料，包括评分作业。完成课程后，您的电子课程证书将添加到您的成就页中，您可以通过该页打印您的课程证书或将其添加到您的领英档案中。如果您只想阅读和查看课程内容，可以免费旁听课程。
退款政策是如何规定的？
您可在付款后两周内，或者在课程第一个班次开课后（对于已启动的课程）两周内，获得全额退款，以其中较晚者为准。获得课程证书后，您便无法再退款；即使您在两周的退款期内完成了课程，也是如此。请阅读我们完整的退款政策。
