What can be a long-term effect of mercury poisoning in children?

Mercury poisoning can have severe long-term effects on children, particularly because their developing brains are more vulnerable to toxic substances. One significant consequence of mercury exposure is learning difficulties. Mercury can disrupt neural development, leading to cognitive impairments. Children may experience issues with attention, memory, and problem-solving skills, which can hinder their academic performance and overall learning ability.

In contrast, the other options suggest positive outcomes that do not occur as a result of mercury poisoning. Improved motor skills, increased intelligence, and enhanced coordination are not associated with mercury exposure; rather, the toxic effects can impede these functions, contributing to learning challenges and other developmental delays.
