Answer Choices:
Correct Answer:
Pests and rodents
Rationale:
🐀 Pests and rodents
🐀 Rodents are vectors that spread infectious diseases such as hantavirus, leptospirosis, and salmonella.
🐀 Their presence in communities is tied to poor housing conditions, sanitation, and waste management.
🐀 Beyond direct infection, they worsen allergies and asthma through exposure to rodent dander and droppings.
🐀 Public health programs emphasize vector control and safe housing improvements to reduce these risks.
🌫️ Carbon monoxide
🌫️ A colorless, odorless gas, carbon monoxide (CO) is produced by incomplete combustion of fuels in poorly ventilated areas.
🌫️ Exposure leads to hypoxia, causing symptoms from headache and dizziness to coma or death.
🌫️ Chronic low-level exposure may contribute to neurological impairments.
🌫️ Community safety relies on CO detectors, ventilation improvements, and safe heating practices.
☢️ Radiation leak
☢️ Radiation exposure from leaks (e.g., nuclear plants, medical mishandling) can cause cell damage, mutations, and cancers.
☢️ Environmental contamination can persist, exposing populations via water, soil, and food chains.
☢️ Long-term effects include increased cancer incidence, reproductive harm, and genetic changes.
☢️ Emergency preparedness involves monitoring, evacuation protocols, and decontamination efforts.
🍄 Black mold
🍄 Black mold (Stachybotrys chartarum) thrives in damp environments, often in poorly ventilated housing.
🍄 Exposure to spores causes respiratory issues, allergies, asthma exacerbations, and skin irritation.
🍄 Vulnerable populations (children, elderly, immunocompromised) face greater risk of severe health effects.
🍄 Addressing mold involves moisture control, structural repair, and environmental remediation.
