Early signs of lead poisoning in adults are often non-specific including: depression, loss of appetite, nausea, diarrhoea, muscle pain, fatigue, malaise, decreased libido and insomnia.
Advanced stages can include kidney damage, nerve and brain damage, and infertility.
In stages of pregnancy, a baby is at greater risk of being premature or with a low birth weight.
Children with lead poisoning are likely to suffer permanent intellectual disability. Because their bodies are constantly growing and developing, children absorb lead at a faster rate than adults and are more prone to ingesting and inhaling dust contaminated with lead, particularly when learning to crawl or walk.
