Chemical causes permanent brain injury

An environmental network on Monday alerted school officials about graduation medals that may be tainted with lead, a chemical that can cause permanent brain injury.

In a statement, the EcoWaste Coalition’s Task Force on Chemical Safety cautioned private and public schools, as well as child care and learning centers, against procuring or accepting medals made of lead alloy or embellished with lead-containing paint.

The EcoWaste Coalition issued the warning after analyzing the heavy metal contents of 30 medals, mostly for kindergarten, preparatory and grade school achievers, lent by colleagues or bought from medal makers in Sta. Cruz and Quiapo, Manila.

School officials were also urged to exercise utmost precaution when choosing and giving medals, reiterating that even very low levels of lead cause brain damage in children.

If the safety of the medals ordered or purchased is not guaranteed, the EcoWaste Coalition exhorted schools to advise recipients not to play with, bite, lick or suck on their medals to avoid the possibility of ingesting lead.

Children and other people are exposed to lead via inhalation, ingestion, and, in minimal cases, through skin absorption.

Using an X-Ray Fluorescence (XRF) device, the group detected lead in 22 of the 30 samples (73%) way above the US allowable limit of 90 parts per million (ppm) for lead in paint or any similar surface coatings.

No detectable levels of lead were found in unpainted, generic "gold," "silver" and "bronze" medals.

A yellow-painted sample led the pack of “dirty medals,” with a whopping 123,800 ppm of lead. The other top five “dirty medals” had elevated levels of lead at 74,400, 48,000, 46,100, 39,500 and 37,000 ppm each.

Two unofficial medals showing the blue and red logo of the Department of Education (DepEd) had 943 and 14,100 of lead, respectively.

“We find it odd that lead, a nasty chemical linked to delayed development, stunted growth, reduced IQ scores and behavioral problems, is used in making medals that are meant to savor a child’s academic and extra-curricular achievements,” said Aileen Lucero of the EcoWaste Coalition’s Project Protect.

“Experts have not identified a safe threshold for lead exposure, especially among kids,” she emphasized.

“This is why we insist that children’s products, including medals, school supplies and toys, should be certified lead-free. We need to take every possible step to reduce lead exposure among our children,” she added.

DepEd should amend its graduation guidelines and add in a policy that will protect youngsters from exposure to lead-containing medals, the EcoWaste Coalition suggested.

Citing information from the World Health Organization, the EcoWaste Coalition warned that “at high levels of acute exposure, lead attacks the brain and central nervous system to cause coma, convulsions and even death.”
