Acerca del Curso

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....

Excellent way of presenting the material.

Simple to understand.

But one suggestion: videos are little lengthier, you may plz look into making shorter videos as tge content is in-depth

The course was quite useful, referring to the harmful effects of chemicals. It also opened my eyes that natural objects can also be dangerous. However, the only issue with this course at 2 weeks' quiz is taken together and some questions in the quizzes are not related to the lectures.

Overall, I appreciate this course.

This course was really informative will look forward to more courses from here keep the good work. Its sad that as a part of the society we are exposed to a lot of chemicals and mainly the growing and the aged too are exposed to a lot of the chemicals. Its good that the necessary steps are taken to reduce it me being from the chemical background am looking into the ppm produced from the refinery section(crude, Motor spirit , LPG...) researching a way to decrease even more pollutants emitting from the Flaring section and the chimney too (although it has reached 0.5 ppm sulfur). This is not a stop we can decrease even more from different sector just keep searching for the puzzle pieces cause the answer is there we just have to find it.

Course material was engaging and streamlined to go through. I appreciated engagement with fellow peers taking the course; however when it came to grading of fellow peers - I found it difficult to truly assess or be assessed, as everyone may be coming in with different backgrounds and knowledge bases. Although, I realize that prompts and what individuals were provided with as part of the grading for 'potential' answers or content, I think there may or may not be biases or ability to assess if another individual truly gained information/knowledge from the course as grading in itself may be subjective. Thank you.

Hello! Thank you very much for the course! I took a lot for myself and learned a lot! How chemicals act on the body and the environment; where and how these substances are investigated. As a teacher, I will apply the material I have learned in lessons for children so that they also know what these substances are? How they get into the body. I will show them video materials so that they also think about how to prevent these substances from entering the environment and the human body, animals, birds.

This is an amazing course from one of the best universities in America and as an internationally renowned university. All lectures are given by experts in their own field. The course is quite challanging and you need to study hard to meet the deadlines.

I would like to thank all thoses at John Hopkins University Bloomsberg School of Public Health for their lectures.

I highly recommend this course for anyone in the chemistry field.

I loved this course, it thought me about the risks are outside our houses or inside of them. As my earlier job was laboratory management. I've learned a lot of chemical effects, and the importance as a manager should take care of the workers we are responsible of, or of the waste management in the industry. I hope everyone will have a chance to take this course. Thank you very much for making me a better knowledged chemist.

This course good for someone who want to know about basic theory how chemical can affect our body, especially for public health POV. Hope in the future John Hopkins Uni can delivered chemical & health online course specific from Industrial Hygiene perspective. Overall, I really enjoy participated in this course.

Compare to previous learned courses it was little bit tough as we should submit answers and will be verified by others students. Also we should verify the same for other two students too. So without well study it is very difficult to do. As it related to Chemicals & toxins, it was an interesting one.

I truly enjoyed taking this course. Especially useful for students who want to understand the very basis to Toxicology and Risk Assessment processes carried for Public health Safety. The case studies mentioned were particularly useful for understanding the concepts in a holistic approach.

I thought the course was very well organized. I found the material to be very informative and well presented. The course provided a good oversight of all the complexities related to chemicals and health and has peaked my interest into this topic. I would like to learn more.

This course was very interesting. I learned a lot about chemicals, how we are exposed to chemicals and the effects of exposure to harmful chemical. I was particularly intrigued by the stor about communities effected by chemicals leaking into their groundwater.

Very interesting online course. Although, I know many of this information I have learnt much different information particularly on the nanotechnology and its occupational health impact, water treatment, arsenic in our food and many others. Thank you very much.

It covered all the basic aspects of chemical-related hazards. How to calculate dose and dosage response relationship, the role of CDC and other bodies in experimenting an impact. Role of the Environmetal Protection Department in defining the exposure limits.

excelente curso, comienza de una manera muy básica para que todos nos encontremos en la misma pagina, para así ir aumentando la complejidad poco a poco hasta lograr tener un entendimiento científico general que nos ayuda de manera cociente en el futuro

It was very expository!

A necessity for everyone, to include those who are not science-oriented.

The knowledge embedded in this course is a step closer to achieving peaceful coexistence between man and his environment.

This is a good training. The thing I liked the most was to evaluate the peers, by doing this, I had to revisit the class content and could memorize the lesson learned. Very well organized class content and system!

The professors were very competent and straightforward, first of all. Lastly, the course was worth doing since it made me understand what chemicals really are and how they intertwine with health and well-being.
