What is it about?

Long-term consequences among children exposed to lead poisoning in wheat flour. The findings observed in relation to the lower cognitive performance and the lower age of exposure to lead, reinforce the need to establish public health policies for the screening of neurotoxic agents (lead, mercury or arsenic), especially in children where the deleterious effect is greater and irreversible. Likewise, it is necessary to develop preventive actions in environmental health, and maintain a high degree of diagnostic suspicion for both acute lead poisoning and chronic cases that can lead to delayed psychomotor development, attention deficit or learning problems.

Why is it important?

The observed findings that relate a lower cognitive performance with a lower age at the time of exposure to lead, reinforce the need to establish public health policies for the screening of neurotoxic agents (lead, mercury or arsenic), especially in children where the effect deleterious is major and irreversible.

It is necessary to develop preventive actions in environmental health, and maintain a high degree of diagnostic suspicion both for acute lead poisoning, as well as in chronic cases that may present with delayed psychomotor development, attention deficit or learning problems.
