Hyde Has PFAS Sampling Expertise
The Hyde staff has the experience to conduct site investigation services with groundwater, surface water, and soil sampling for PFAS chemicals. Because PFAS contamination must be detected at the parts per trillion level, rather than the parts per billion or parts per million level, special care must be taken during the sample collection process to ensure that contamination from other sources does not occur. Our Hyde contamination experts go through rigorous training for these situations.
PFAS Health Effects
Scientists are still learning about the health effects that various PFAS can have on the body. The more widely used substances, like PFOS, PFOA, PFHxS, and PFNA, have been studied more than other PFAS.
A large number of studies in people have examined possible relationships between levels of PFAS in blood and harmful health effects in people. However, most of these studies analyzed only a small number of chemicals, and not all PFAS have the same health effects. This research suggests that high levels of certain PFAS may:
- Increase cholesterol levels
- Decrease how well the body responds to vaccines
- Increase the risk of thyroid disease
- Decrease fertility in women
- Increase the risk of serious conditions like high blood pressure or pre-eclampsia in pregnant women
- Lower infant birth weights; however, the decrease in birth weight is small and may not affect the infant’s health
Several federal agencies are currently in the process of evaluating human health risks of PFAS. Most people in the U.S. have PFAS in their blood, similar to the low levels observed in blood for other industrial compound classes like flame retardants and plasticizers. While a blood test can determine the amount of PFAS in one’s body, there is currently not enough research to determine the level at which one would expect to see health problems.
