  1. Carbon monoxide

  2. Nitrogen dioxide

  3. Particulate matter

  4. Ozone

Show answer
Correct Option: C
Explanation:

Particulate matter, especially fine particles (PM2.5), can cross the placenta and reach the fetus, leading to adverse effects on fetal development.

What is the primary source of particulate matter in urban areas?

  1. Industrial emissions

  2. Vehicle exhaust

  3. Power plants

  4. Construction activities

Show answer
Correct Option: B
Explanation:

Vehicle exhaust, particularly from diesel engines, is a major contributor to particulate matter pollution in urban environments.

How does air pollution affect the health of pregnant women?

  1. Increased risk of preterm birth

  2. Low birth weight

  3. Gestational diabetes

  4. All of the above

Show answer
Correct Option: D
Explanation:

Air pollution has been linked to an increased risk of preterm birth, low birth weight, gestational diabetes, and other adverse pregnancy outcomes.

Which of the following is NOT a recommended measure for pregnant women to reduce their exposure to air pollution?

  1. Staying indoors on high-pollution days

  2. Using an air purifier at home

  3. Walking or biking instead of driving

  4. Smoking cigarettes

Show answer
Correct Option: D
Explanation:

Smoking cigarettes during pregnancy is strongly discouraged, as it not only harms the mother's health but also increases the risk of adverse pregnancy outcomes.

What is the term used to describe the process by which air pollutants can cross the placenta and reach the fetus?

  1. Transplacental transfer

  2. Fetal exposure

  3. Maternal-fetal transfer

  4. Placental exchange

Show answer
Correct Option: A
Explanation:

Transplacental transfer refers to the process by which substances, including air pollutants, can pass from the mother's bloodstream to the fetal circulation through the placenta.

Which of the following air pollutants has been associated with an increased risk of neural tube defects in newborns?

  1. Carbon monoxide

  2. Nitrogen dioxide

  3. Particulate matter

  4. Ozone

Show answer
Correct Option: B
Explanation:

Nitrogen dioxide exposure during pregnancy has been linked to an increased risk of neural tube defects, such as spina bifida, in newborns.

What is the recommended level of particulate matter (PM2.5) exposure for pregnant women, according to the World Health Organization (WHO)?

  1. 10 µg/m³

  2. 25 µg/m³

  3. 50 µg/m³

  4. 75 µg/m³

Show answer
Correct Option: A
Explanation:

The WHO recommends that pregnant women limit their exposure to particulate matter (PM2.5) to 10 µg/m³ as an annual average.

Which of the following is NOT a potential health effect of air pollution on pregnant women?

  1. Increased risk of preeclampsia

  2. Low birth weight

  3. Asthma

  4. Allergies

Show answer
Correct Option: D
Explanation:

While air pollution has been linked to an increased risk of preeclampsia, low birth weight, and asthma, it is not typically associated with allergies.

What is the term used to describe the process by which air pollution can cause inflammation and oxidative stress in the body?

  1. Transplacental transfer

  2. Fetal exposure

  3. Maternal-fetal transfer

  4. Placental exchange

Show answer
Correct Option:
Explanation:

Oxidative stress refers to the process by which air pollutants can generate free radicals and cause inflammation in the body, leading to adverse health effects.

Which of the following air pollutants has been associated with an increased risk of autism spectrum disorder (ASD) in children?

  1. Carbon monoxide

  2. Nitrogen dioxide

  3. Particulate matter

  4. Ozone

Show answer
Correct Option: C
Explanation:

Exposure to particulate matter during pregnancy has been linked to an increased risk of autism spectrum disorder (ASD) in children.

What is the recommended level of nitrogen dioxide (NO2) exposure for pregnant women, according to the United States Environmental Protection Agency (EPA)?

  1. 100 µg/m³

  2. 200 µg/m³

  3. 300 µg/m³

  4. 400 µg/m³

Show answer
Correct Option: A
Explanation:

The EPA recommends that pregnant women limit their exposure to nitrogen dioxide (NO2) to 100 µg/m³ as an annual average.

Which of the following is NOT a recommended measure for pregnant women to reduce their exposure to ozone?

  1. Staying indoors on high-ozone days

  2. Using an air purifier at home

  3. Exercising outdoors in the early morning or evening

  4. Swimming in chlorinated pools

Show answer
Correct Option: D
Explanation:

Swimming in chlorinated pools does not reduce exposure to ozone, which is an outdoor air pollutant.

What is the term used to describe the process by which air pollutants can affect the development of the fetal brain?

  1. Neurotoxicity

  2. Developmental neurotoxicity

  3. Neurological impairment

  4. Cognitive dysfunction

Show answer
Correct Option: B
Explanation:

Developmental neurotoxicity refers to the process by which air pollutants can harm the developing brain of the fetus, leading to adverse effects on cognitive function and behavior.

Which of the following air pollutants has been associated with an increased risk of stillbirth?

  1. Carbon monoxide

  2. Nitrogen dioxide

  3. Particulate matter

  4. Ozone

Show answer
Correct Option: A
Explanation:

Exposure to carbon monoxide during pregnancy has been linked to an increased risk of stillbirth.

What is the recommended level of ozone (O3) exposure for pregnant women, according to the World Health Organization (WHO)?

  1. 100 µg/m³

  2. 200 µg/m³

  3. 300 µg/m³

  4. 400 µg/m³

Show answer
Correct Option: A
Explanation:
