A recent study by the Medical Research Council showed that about 20% of suburban homes, even relatively new houses, may contain lead-based paint. And even though unleaded petrol has helped to lower lead levels in the environment, the levels are still unacceptably high. Children and unborn babies are particularly vulnerable to the effects of lead exposure, which can include learning and behavioural problems, anaemia and abnormal organ development.

Take action:
Wash hands frequently, especially before eating. Stay away from busy roads, peeling paint and where renovations may disturb lead-based paint. Playing on grass is generally better than soil or dusty surfaces. Control dust levels at home, sweep up paint chips, and keep play areas and toys clean. A nutritious diet also helps prevent lead from being absorbed into the body. If you think you may have been exposed, ask your doctor to check your lead levels.
