One in three children globally suffers the effects of lead poisoning each day. A lack of awareness and symptoms means that they continue to be unknowingly compromised. Children under five are particularly vulnerable to the neurotoxin, absorbing 4–5 times as much ingested lead as adults from a given source. This causes irreversible and lifelong physical, neurological and cognitive impairment, wreaking havoc in still-developing organs and systems. As lead exposure increases, the range and severity of symptoms also increases.
