Which of the following environmental hazards is known to have a greater impact on children than on adults?

While mold can cause respiratory issues and allergic reactions in both children and adults, its impact is not exclusively greater on children. Adults may experience similar adverse effects, particularly if they have existing respiratory conditions, making mold less of a distinguishing hazard for children compared to lead-based paint.

Asbestos exposure can lead to serious health issues such as lung cancer and mesothelioma, but its effects are generally seen after long-term exposure and are not necessarily more severe in children than in adults. Both age groups are at risk, but the latency period for symptoms means that immediate impacts are unlikely to differ significantly by age.

Carbon monoxide poisoning can affect individuals of all ages, but the impact does not disproportionately affect children over adults. Symptoms such as headache, dizziness, and confusion can occur in anyone exposed to high levels, regardless of age, making this hazard less specific to children than lead-based paint.
