MANILA, Philippines — The Department of Health (DOH) yesterday warned the public against possible health risks linked to toxic school supplies.

Citing an advisory of the Food and Drug Administration (FDA), Health Secretary Francisco Duque III said lead-contaminated school materials have long-lasting effects on children’s health.

“Lead exposure in children may have permanent consequences, such as neurological damage, delayed mental and physical development, attention and learning deficiencies, impairment of cognitive functions of the brain and hearing problems,” Duque said.

He said long-term exposure from inhalation of cadmium may also result in chronic obstructive pulmonary diseases, emphysema and chronic kidney diseases.

Exposure to mercury even in small amounts, he said, may cause serious health problems and is a threat to the development of the fetus in pregnant women.

Duque said that children tend to put objects in their mouth, thereby exposing themselves to hazardous substances.

“So be careful when you buy school supplies for your children,” he said.

Last year, Duque said, the FDA found unacceptable levels of heavy metals, including lead, cadmium and mercury, in a number of school materials.

Among these contaminated school supplies are the 12-in-1 pencil, Fairyland (brand) 16 Crayons and Leehoe (brand) Glitter Fabric Paint Pens.

“Read carefully the labels to know if it is appropriate for your children and registered with our FDA for safety, and immediately consult a doctor in cases of accidental ingestion or any adverse health effects while using school supplies,” Duque said.
