Household chemicals impair children’s immunity: Study

Exposure to chemicals in early childhood
may affect a kid's response to vaccinations.
A new study records a poorer response to vaccines in children with higher levels of PFCs in their blood.

PFCs is short for perfluorinated compounds (PFCs), a group of synthetic chemicals commonly used in nonstick cookware, carpets, upholstery, food packaging and more. Previous studies have shown that the chemicals are present in most people’s bloodstreams.

In the first study of its kind on humans, researchers from the United States and Denmark found that high levels of exposure to these chemicals in early childhood may be associated with a reduced response to two routine immunizations.

They followed 587 children in the Faroe Islands (between Iceland and Norway) between 1999 and 2001, where a high intake of seafood is linked with increased exposure to PFCs.

The two vaccines in question are the tetanus and diphtheria immunizations that are given at 3, 5 and 12 months of age and a booster shot at age 5.

The study shows that all five PFCs in the study appeared to be linked to lower antibody levels. The children’s response to tetanus and diphtheria vaccines at age 7 was only half of what it should have been if they showed high levels of PFCs in their blood.

The next questions the researchers need to answer are:
  • Does this link point to a general immune system dysfunction and 
  • Could this also affect their risk of infections, allergies or cancer?

The findings appear in the Jan. 25 issue of the Journal of the Medical Association.

Reduce your chemical exposure at home

Experts suggest avoiding products made with PFCs as much as possible, including nonstick cookware and microwave popcorn.
The 5000 Exec is a powerful
general purpose air purifier.

Homeowners should also vacuum their rugs and upholstery often to reduce household dust levels.

A portable air purifier with activated carbon and HEPA air filters can also help in cleaning the air and controlling the levels of chemicals, gases, odors and dust.

AllerAir’s general purpose air purifiers feature a deep-bed activated carbon filter that can remove the widest range of gaseous pollutants. They also feature high efficiency particle filters for dust and other particulate matter, pre-filters and optional UV germicidal filtration for extra protection against biological contaminants such as bacteria, viruses and mold.

Every household is different and every indoor air environment may require a slightly different solution, which is why AllerAir offers one of the most extensive product lines and customizable options on the market.

You can even remove odors and chemicals from small, enclosed spaces like drawers, cabinets, closets, refrigerators, litter boxes and more with AllerAir's Air Purifiers for Small Spaces.
