Question

1. complete the table to show the potential negative affects of tropospheric ozone.

effect	details
damage to plants
damage to humans
damage to materials

Explanation:

• Oxidizing: Tropospheric ozone is a strong oxidizer that reacts with other substances, breaking down organic and some inorganic compounds by stealing electrons, which alters their chemical structure and function.
• Damage to plants: Ozone enters plant stomata, damaging leaf cells (creating visible necrotic spots), reducing photosynthesis efficiency, stunting growth, and lowering crop yields or plant survival rates.
• Damage to humans: Inhaled ozone irritates and inflames the respiratory tract, worsening asthma and chronic obstructive pulmonary disease (COPD), reducing lung function, and causing chest pain, coughing, or shortness of breath; long-term exposure may lead to permanent lung damage.
• Damage to materials: Ozone reacts with rubber, plastics, and some fabrics, causing cracking, brittleness, fading, or degradation of the material's structural integrity over time, shortening the lifespan of items like tires, outdoor furniture, and textiles.

Answer:

Effect	Details
Damage to plants	Enters stomata, damages leaf cells (necrotic spots), reduces photosynthesis, stunts growth, lowers crop yields and plant survival
Damage to humans	Irritates/inflames respiratory tract, worsens asthma/COPD, reduces lung function, causes chest pain/coughing; long-term exposure may cause permanent lung damage
Damage to materials	Degrades rubber, plastics, and fabrics, causing cracking, brittleness, fading, and reduced structural integrity, shortening material lifespan
