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 My 1 missing star goes to the kinda' outdated information presented in most of the discussions.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?

This course actually gave an idea about how are we exposed to chemicals and the health effects too .this course stuffed some knowledge about the environmental health effects but those survey part revolved around America. if it was a world survey, it could have been interesting. Overall it's good.

I am really grateful to have joined this course. I am a Chemical Engineering student and I learnt how chemicals can affect our environment and our physiologies either in a positive or in a negative way; and what should be our approach as a member of the society.

Siento que debió de haber más temas científicos, relacionados en la interacción de los químicos y el cuerpo humano. De igual manera creo que el sistema para evaluar no es tan eficiente; las calificaciones y las preguntas son un tanto subjetivas.

I have found the course really useful to understand better the impact of chemicals on health, either harmful and beneficial. I now have a clearer idea of the exposure to chemicals and the importance of law regulations to control health outcomes.

Yes it is overview of chemicals, in this course more empahesised on tabacco produts chemicals, water treatment and contamination part was very good. air born chemicals must be covered more instead of tabacco

This course helped me realise how we all our exposed to harmful chemicals everyday. It provided a lot of content regarding what happens when toxins reach the body. This course was very informative and helpful

At start it was a bit boring...and too much information about the USA strategies...I thought that there would be more information about specific chemicals and not so much about legislation...

this course was neither about biology nor about chemistry as i expected. however, it was still really interesting and i learnt a lot about the public policy surrounding chemicals.

Course is good for a general understanding. But is discusses public health labs and government policies of USA. So the course might be somewhat irrelevant to non-Americans.

wonderful videos and explaining the complexities associated with chemicals at all levels eloquently. This course has utilized my time really well.

Very interesting and there is a lot of sources to attain new knowledge about chemical management and public health-related to those chemicals

I found this course useful since it addresses such an important topic that requires reliable information and educated people on this issue.

It was a great course which suits a beginner as it discusses all necessary aspects of chemicals to our daily lives.

Great foundational course for learners curious about the impact of chemicals on our physical and human environment.

I have learned many things in this course. It is not only useful for academics but also for daily life. thank you.

THE COURSE WAS REALLY INFORMATIVE AND ALL THE TOPICS WERE EXPLAINED IN A SIMPLE MANNER. ENJOYED THE COURSE.

Chemicals and Health: I love the course, Explanations, Examples and Lecturers are awesome
