Anyone concerned about their health should consult their doctor.
The hazard posed by PAHs (found in some types of clay targets) varies between compounds, with some being persistent in the environment and having a potential to bio-accumulate in food webs. A number of PAHs are classified as carcinogenic to humans and can be absorbed through ingestion, inhalation or skin contact. Potential health effects are largely linked to levels of exposure.
Lead exposure may occur from ingestion of contaminated soil or dust or from drinking contaminated water. People with elevated blood lead levels rarely show obvious symptoms. However, exposure can cause:
- headaches, tiredness, weakness and joint pain
- reduced brain function, including memory loss and difficulty concentrating
- heart, blood and blood pressure problems
- damaged kidneys
- reduced fertility.
Infants, children and pregnant women are especially vulnerable. Lead can affect young children’s brain development and their ability to learn.
Pregnant women can pass lead on to their unborn babies during pregnancy or to an infant during breastfeeding.
