How much do you know about environmental health?
We’re back for another round of testing your knowledge about environmental health!
By now, you probably realize that your environment can make you sick. Harmful exposures anywhere in your environment might affect your health. In the latest quiz, we saw that harmful exposures include more than exposures to toxins. Any exposure to hazardous substances or dangerous events in your environment can cause harmful health effects. Environmental public health is about protecting groups of people from environmental threats to their health, safety, and well-being.
Try to answer these questions.
- Some populations are at a higher risk of the effects of toxic substances than others. These populations include
- Young children
- Older adults
- Pregnant women
- All of the above
- A and B
- Everything is made of chemicals, so you come into contact with them every day. Which of these statements about chemical exposures is not true?
- Exposures to all sorts of chemicals are normal and frequent occurrences.
- Exposure to any amount of any chemical can harm your health.
- Frequency and length of exposure both play a role in determining whether you get sick from exposure.
- Chemicals in pesticides or herbicides can pollute soil, water, plants grown for food, and livestock.
- To get sick from exposure to an environmental contaminant, a certain amount of it must enter your body.
- Yes or No: The most common flood deaths occur when a vehicle is driven into hazardous floodwater.
- ATSDR supports cities and organizations that are reclaiming “brownfields.” What is a “brownfield” site?
- A meadow or pasture during winter
- Desert land with no irrigation
- An area with abandoned structures
- Contaminated area that must be cleaned up before re-use.
- Which of the following statements about asthma is false?
- Asthma causes wheezing, breathlessness, chest tightness, and nighttime or early morning coughing.

- In most cases, we don’t know what causes asthma, and we don’t know how to cure it.
Environmental Public Health Quiz Answers
- Answer: D. All of the above.
- Children are especially vulnerable to environmental contaminants due to their rapid development from before they are born through early childhood.
- This means that when pregnant women are exposed, they are also exposing their unborn child to the substance.
- Young children are more at risk for contact with harmful substances because they have more contact with the ground and commonly put everything in their mouths.
- Older adults may be more at risk of chemical exposure because they may have weak immune systems, more sensitive lungs, chronic diseases, and age-related reactions to drugs.
- Answer: B is false.
- Chemical exposures can be harmful if they exceed certain limits. Also, a certain amount of a harmful chemical must enter your body to make you sick. Harmful chemicals can get into your body if you breathe, eat, or drink them or if they are absorbed through your skin.
- People respond to chemical exposures in different ways. Some people may come into contact with a chemical and never be harmed. Others may be more sensitive and get sick. Sometimes illness happens only if you are exposed to a harmful substance for a long time.
- Yes. Cars or other vehicles won’t protect you from floodwaters. They can be swept away or may stall in moving water. As little as six inches of water can cause you to lose control of your vehicle.
- Answer: D. Contaminated area that must be cleaned up before re-use.
- According to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, the term “brownfield site” means real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant.
- ATSDR includes brownfields as a type of land reuse site. Land reuse sites are slated for redevelopment but may have chemical contamination.
- Answer: B. In most cases, we don’t know what causes asthma, and we don’t know how to cure it. However, asthma can be controlled by working with a healthcare professional, taking medication, avoiding asthma triggers, and removing triggers from your environment.
