What is a common consequence of lead exposure in children?

Developmental delays and learning difficulties are well-documented consequences of lead exposure in children. Lead is a potent neurotoxin, and its effects on developing brains can be severe. Exposure to lead, especially in early childhood, can interfere with the development of the nervous system, leading to cognitive deficits that may manifest as lower IQ, difficulties in concentrating, and problems with memory.

Additionally, lead exposure has been linked to developmental delays, where children may fail to achieve developmental milestones as expected. These impacts can have lasting effects on a child's educational performance and overall academic achievement.

In contrast, the other options do not reflect the true consequences of lead exposure. Increased physical strength, enhanced cognitive abilities, and improved motor skills are not associated with lead exposure and do not occur as a result of lead toxicity. Recognizing the specific negative outcomes linked to lead exposure is crucial for understanding the risks that lead poses to children's health and development.
