Today’s 1:5:10:365 Tip for becoming a better steward for our home and planet is about lead in our homes.

1:5:10:034 Tip:  Lead-based paint has been used in pre-1980 buildings and can be screened using the lead test kits discussed in :033. This is a screening tool only and does not answer the question about how much lead is present. Another technique is to submit a small chip of the material for laboratory analysis (this requires damaging the painted surface – which may not matter if the paint is already deteriorating).

Lead containing dust from deteriorating paint is frequently the greatest risk for exposure. In Additional Information I have posted an EPA link to a PDF describing a method for collecting dust using baby wipes that can be submitted to a laboratory for analysis.

One method of professional testing is called Xray fluorescence. This machine is expensive and requires training so it is not a do it yourself method, but it is generally the most cost effective since a consultant can evaluate several hundred different surfaces very quickly.
