Multiple choice

How does nitrogen fertilizer affect human health?

  1. It can cause respiratory problems.

  2. It can increase the risk of cancer.

  3. It can contaminate drinking water.

  4. It can cause neurological problems.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nitrogen fertilizer can contaminate drinking water with nitrates, which can cause a variety of health problems, including blue baby syndrome and gastrointestinal problems. Nitrates can also be converted to nitrites, which can react with hemoglobin to form methemoglobin, which can lead to oxygen deprivation.

Multiple choice

How does phosphorus fertilizer affect human health?

  1. It can cause respiratory problems.

  2. It can increase the risk of cancer.

  3. It can contaminate drinking water.

  4. It can cause neurological problems.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Phosphorus fertilizer can contaminate drinking water with phosphates, which can cause a variety of health problems, including kidney stones and cardiovascular disease. Phosphates can also contribute to the formation of disinfection byproducts, which have been linked to cancer.

Multiple choice

  1. It can cause respiratory problems.

  2. It can increase the risk of cancer.

  3. It can contaminate drinking water.

  4. It can cause neurological problems.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Potassium fertilizer can contaminate drinking water with potassium, which can lead to a variety of health problems, including kidney stones and cardiovascular disease. Potassium can also contribute to the formation of disinfection byproducts, which have been linked to cancer.
