PFAS, a class of "forever chemicals", have been linked to serious health problems, including cancer and liver problems.
PFAS Problem
PFAS are a class of "forever chemicals" linked to serious health problems, including cancer, liver issues, and birth defects. There are over 12,000 of these chemicals.
Recent testing of sports turf found a toxic brew of PFAS compounds, including 6:2 FTOH and PFOS. The EPA has revised its health advisory for PFOS, stating that no level of exposure in drinking water is safe.
PFAS are not just a problem in water, but also in the air, fish, and soil. They're even found in artificial turf, which is used in sports fields.
A Chinese study linked PFAS in the brain to higher levels of brain cancer. This raises concerns about the safety of artificial turf for athletes.
Proving the health effects of PFAS is challenging, as they're found in many environments. It's hard to determine whether exposure to PFAS in artificial turf is causing health problems in athletes.
Artificial turf contains PFAS, including 16 types, according to testing done on the Phillies artificial turf. This is a concern for athletes who play on these fields.

Non-Toxic, but Exceptions Apply

Artificial grass is often less toxic than chemically treated natural grass, but there are exceptions to consider.
Some dogs or cats may be tempted to chew or lick an artificial grass surface, especially a newly installed one. This is typically fine, but lead is a known exception.
Older or imported artificial grass backings might be treated with lead, which can harm pets and children if ingested. This is why it's crucial to opt for lead-safe, non-toxic artificial grass, made or inspected in the United States.
Artificial grass can be safely enjoyed by every member of your family, including four-legged ones, if you choose the right product.
Here are some key points to consider:
- Look for artificial grass made or inspected in the United States to minimize the risk of lead contamination.
- Check the product's certifications and labels to ensure it meets safety standards.
- Choose a reputable manufacturer that prioritizes non-toxic and lead-free materials.
Materials in Synthetic Turf Manufacturing
Synthetic turf is made from three main plastics: polypropylene, polyethylene, and nylon. These plastics are durable and UV-resistant, making them a good choice for outdoor use.
Manufacturers in the USA adhere to strict safety regulations, ensuring that their synthetic turf is lead-free and free from harmful chemicals. However, regulations in other countries may not be as strict, which can lead to lower-quality materials being used.

Artificial turf made in the USA is a safer choice for families and their homes. This is because American manufacturers are required to use higher-quality materials that are safer for children and pets.
The plastics used in synthetic turf are designed to mimic the appearance and feel of natural grass. They are also designed to withstand heavy foot traffic and the sun's UV rays.
Here are the three main plastics used in synthetic turf manufacturing:
- Polypropylene
- Polyethylene
- Nylon
These plastics can be used to make high-quality synthetic turf that is safe for families and their homes.
Exposure and Risks
Artificial turf can contain toxic chemicals, including PFAS, which are linked to cancer, liver problems, and other serious health issues.
In 2019, the Environmental Protection Agency acknowledged that synthetic turf contains toxic chemicals, some of which are known to cause cancer.
PFAS are found in water, air, fish, and soil at locations across the nation and the globe, making it challenging to prove health causality.

Exposure to PFAS can occur through touching or swallowing crumbled rubber pellets, inhaling chemicals that off-gas into the air, or dermal contact and absorption through the skin or open wounds.
According to The Guardian, testing of sports turf found a toxic brew of PFAS compounds, including 6:2 FTOH and PFOS.
A Chinese study linked PFAS in the brain to higher levels of brain cancer.
The risk of injury from artificial turf is lower compared to natural grass, thanks to innovations such as improved shock absorption layers and softer fibers.
However, the presence of PFAS in artificial turf poses a significant risk to human health, particularly through skin contact and absorption.
The EPA recently revised its health advisory for PFOS to state that no level of exposure to it in drinking water is safe.
Here are some ways you can be exposed to PFAS in artificial turf:
- Touching or swallowing crumbled rubber pellets
- Inhaling chemicals that off-gas into the air
- Dermal contact and absorption through the skin or open wounds
- Ingestion through food or water sources that have been contaminated with PFAS
A 2022 report by the city of Boston stated that no new artificial turf can be installed in city parks due to the presence of toxic chemicals.
A 2023 bill in California aims to ban the manufacturing and sale of artificial turf containing PFAS, highlighting the growing concern over the safety of artificial turf.
If you're considering installing artificial turf, look for PFAS-free options to minimize exposure risks.
Keep in mind that even PFAS-free artificial turf may still pose risks, such as heat hazards, which can be uncomfortable and potentially harmful to children and pets.
Here are some safety features of high-quality artificial turf:

General Information and Conclusion
Artificial turf is a common surface found on many sports fields and playgrounds.
The ideal situation is a grass field that doesn't require pesticide use, but unfortunately, most public grass fields might require some level of pesticides to withstand constant sports and activities.
Pesticide application might be used or done once or twice a year, and the potential exposure to pesticide chemicals from treated grass would be reduced, particularly if it rains.
However, with artificial turf, the exposure to chemicals starts from day one and increases with time as the turf wears down.
Children will bring those chemicals home into the car and homes when pieces of pellets and grass start to come off and stick to their bodies in clothes.
In situations where artificial turf is unavoidable, washing hands as soon as kids are done playing is a good practice to follow.
I wish there would be a study addressing the potential harm caused by pesticide use on grass fields, but for now, it's a trade-off between two potentially harmful options.
