Touches on an interesting and enlightening variety of subjects, while keeping a practical and applicable milieu of study. Lectures carry solid explanation of concepts and remain compact enough to be suitable for recreational study or a career-guiding step. Assignments and concepts progressed in a moderately cohesive manner, but the rapidly-changing subjects (and professors), make for a particular sort of trouble in garnering the attention for any further critical thought on each subject than what is evidently available. I would appreciate if the assignments guided you more in the direction, no matter how mildly it may do so, of realistic problem solving as opposed to mere observation of data. Of course this is beyond the scope of a 6-week course, but this course leaves you with little conceptualization of how to carry the knowledge to a practical ground, and instead serves with the familiarity of concepts and issues.

I might have to shift to public health after attending this course ;-)
I like that the subjects really fit "beginners"; how it tried to explain the information as simple as possible as I could just imagine those without background in hard science to comprehend some details. The lecturers were all credible and gave their best to explain topics in the most comprehensive way. My 1 missing star goes to the kinda' outdated information presented in most of the discussions. Some go back as far as 2000s. The course might need some refreshing or revision to be updated.

I am very happy to have taken this course. I can boldly say that my understanding of the relationship between chemicals and human health has greatly appreciated. I have learnt a lot of new things that will help me in my career in environmental science and sustainability. A very big "Thank you" to the course instructors and to Johns Hopkins University for providing the opportunity. Thanks to all the Coursera team members who kept encouraging me to finish this course...your words of encouragement were magical!

Very informative course! I recommend that you review your peer review method. The answers to the last requirement (demonstrate what you've learned) are quite objective, with the correct answers flashed to compare with the learner's answers. My answers reflected the correct answers but the reviewers gave very low marks. i don't understand why. Who evaluates your reviewers in this case?

Interesting course, well structured, easy to follow even for non-native speakers.
I do not give 5 stars as it is too much centered on U.S. reality. I would suggest to introduce also some example coming from the European community. For example Reach regulation, Echa, EFSA activities would deserve some space in this course.
Any idea for an advanced level?
