Question

Which item or items contribute to heart disease.

a. ozone and particulate matter
b. ozone and nitrogen oxides
c. nitrogen oxides and carbon monoxide
d. carbon monoxide and sulfur dioxide

Answer 1

Contributors to heart disease from air pollution include carbon monoxide, nitrogen oxides, particulate matter, sulfur dioxide, and ozone; these substances can impair respiratory health and reduce oxygen supply to vital organs.

Step-by-step explanation:

The items that contribute to heart disease are primarily related to air pollution, which includes substances such as carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), sulfur dioxide (SO2), and ozone (O3). Carbon monoxide is a colorless, odorless gas that can reduce oxygen delivery to the body's organs, potentially leading to heart disease. Nitrogen oxides and sulfur dioxide are also of concern, as they can react in the atmosphere to form fine particulate matter that can penetrate deeply into the lungs and enter the bloodstream, contributing to heart and lung diseases, such as asthma and bronchitis. Ground-level ozone is not emitted directly but is formed by the reaction between nitrogen oxides and volatile organic compounds in the presence of sunlight, and inhaling ozone can trigger a variety of health problems, including those related to heart disease.

Answer 2

The items that contribute to heart disease are option C. Nitrogen oxides and carbon monoxide. These items are commonly part of the polluted air in the environment. Carbon monoxide is a product in combustion that when inhaled, it results in the reduction of oxygen flow in the bloodstream, which is highly dangerous especially to those who have an existing heart disease. In addition, nitrogen oxides react to other particles in the air, which could affect and penetrate areas of the body when inhaled and will result to respiratory disorders and worsen heart conditions.
