Lead in Drinking Water: Homes and Schools

Lead is a potent neurotoxin that is commonly present in our environment and can have serious, irreversible cognitive and behavioral impacts, particularly in children. Historically, most lead exposure has occurred through inhaling leaded-gasoline combustion products in the atmosphere; this contribution has drastically declined due to the global phase-out of leaded gasoline. Other sources of...

Testing for Lead In School Drinking Water: A Summary of Sampling Protocols

Low level lead exposure has been linked to neurobehavioral and cognitive effects in children.1 No “safe” level of lead exposure exists and efforts should be made to reduce exposures to as low as possible. The phasing out of lead in gasoline, residential paints, and solder in food cans has substantially decreased blood lead levels among the general population, but residual sources still exist....

Can a single strand of hair be used to monitor exposure to toxic metals?

Hair is a growing keratinous tissue comprised of sulfur. As such, the sulfur in the hair can bind the many elements present in circulating blood, including toxic metals. Since hair is metabolically inert once formed, the elements retained in the tissue become locked in, so as the hair grows it can record changes in blood element concentrations over time. Using laser ablation on single strands of...
