What is the black stuff on NFL field?
A new artificial turf system was developed in the early 2000s based on "crumb rubber." The black crumbs are small pieces of styrene-butadiene rubber made from grinding up old vehicle tires. The tire crumbs are poured in between the artificial grass blades, giving the artificial fields more cushion and support.
Called styrene butadiene rubber, or “crumb rubber,” the new turf contained tiny black crumbs made from pulverized car tires, poured in between the fake grass blades. The rubber infill gave the field more bounce, cushioned the impact for athletes, and helped prevent serious injuries like concussions.
Turf is a playing surface that imitates traditional grass fields but is made of small plastic blades of grass that are held in place with millions of pebble-sized, black rubber beads that serve as “dirt.” These beads come from recycled tires and are referred to as “crumb rubber.”
The black stuff on artificial turf that you sometimes see flying up behind a rolling baseball or sliding player on TV is, for the most part, tiny bits of old recycled tires called crumb rubber infill. Infill is added across the entire area of an artificial grass installation and plays a number of important roles.
"Crumb rubber contains benzothiazole, which exerts acute toxicity and is a respiratory irritant and a dermal sensitiser. Carbon black, which makes up 20-40% of crumb rubber, has been identified as a cancer-causing chemical by California's Office of Environmental Health Hazard Assessment.
What chemicals are in the crumb rubber? Crumb rubber is made from recycled tires. Tires are manufactured from natural and synthetic rubber along with many chemical additives, including zinc, sulfur, black carbon, and oils that contain polycyclic aromatic hydrocarbons (PAHs).
The price of 33% Crumb Rubber products is between ₹16 - ₹22 per Kg.
The Synthetic Turf Council, an organization that represents manufacturers of artificial turf, insists that the materials used in synthetic grass products are safe, and the Consumer Product Safety Commission (CPSC) says that there is no elevated health risk from playing on artificial turf.
No, synthetic turf fields made with crumb rubber infill do contain chemicals that have been shown to cause cancer. However, what is critical to consider are the routes of exposure and potential dose someone receives.
- Gently apply pressure to the wound to help stop any bleeding.
- Once bleeding stops, rinse the wound with plain water and pat the area dry with a cloth. ...
- Apply an antiseptic ointment to the wound. ...
- You may want to cover the abrasion with a hydrogel dressing and a sterile gauze.
What are turf pellets purpose?
Turf fields have three main layers. The top layer consists of plastic blades that simulate the look of regular grass, the second layer is black turf pellets that support the plastic grass and help provide cushion and support, and the bottom layer of carpet helps with drainage (Cheng et al., 2014).
Specifically, players have a 28% higher rate of non-contact lower extremity injuries when playing on artificial turf. Of those non-contact injuries, players have a 32% higher rate of non-contact knee injuries on turf and a staggering 69% higher rate of non-contact foot/ankle injuries on turf compared to grass.
Sixteen NFL stadiums have real grass. Nine of them have Bermuda grass, four have Kentucky bluegrass, two have Desso Grassmaster and one has a combination of different grasses.
Commonly used base materials are granulated crumb rubber produced from used tires, flexible plastic pellets, sand, and rubber-coated sand. A combination of sand and crumb rubber is sometimes used.
Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes becomes more liquid. Microscopic fibers within the vitreous tend to clump and can cast tiny shadows on your retina. The shadows you see are called floaters.
So soft you can walk barefoot, and unlikely to cause injury if thrown. Rubber mulch makes backyard swingsets much safer because it does not absorb water or freeze like traditional mulch does.
Analysis of the vapours that are released from tires reveals the presence of numerous compounds that constitute the “tire smell.” Some of these, mostly those emanating from the hydrocarbon oils, are potentially toxic. Some, like benzopyrene, are carcinogenic.
It all comes down to a simple question: Are tires toxic? The short answer is that yes, they are. Tires contain a host of chemicals and metals that should not be in the human body. They do gradually erode and break down, leaching those chemicals into the environment.
Generally 10% - 20% of the weight of an old passenger car tire usually consists of steel. An average shredding plant produces about 100-200 MT of steel tire wire and its quality can vary according to technology, storing and management systems adopted by the producing plants.

How much crumb rubber is on a football field?
Environment and Human Health, Inc.'s study of artifcial turf infill estimates that a square foot of a field with between two and three inches of in-fill would have between five and seven kilograms of tire crumbs, translating to 11 to 15 pounds.
The wires, which make up roughly 10-20% of the tire (or 2.5 lbs.), are extracted in the beginning stages of the recycling process. The wire is made of steel and is easily drawn out by magnets. Removing the metal early saves wear and tear on machinery further down the line.
Liberty Tire Recycling has the nationwide capacity to produce more than 400 million pounds of crumb rubber annually for a wide variety of commercial applications.
It can contaminate the soil and shed microplastics into the environment which are harmful to living beings; Heat and soil contamination harm earthworms, who are vital for a healthy garden; It can make flooding worse as it doesn't provide an absorbant surface to regulate rainfall.
Children may be exposed to chemicals in turf either from touching or swallowing the crumbled rubber pellets that make up the backing, or possibly from breathing chemicals that off-gas into the air, according to the Children's Environmental Health Center of the Icahn School of Medicine at Mount Sinai .
No. Artificial grass is made from the same type of plastic that is used in common household products. We come into contact with these materials on a daily basis and there have been no proven harmful effects. If you think about it, turf is really just plastic.
Industry representatives and manufacturers say that crumb rubber is safe for children to play on because the manufacturing process binds the various components of tire, including carbon black and solvents, into a “matrix” that makes it impossible for them to leach out.
Dangers of rubber tire mulch
Stories have come out about dangerously high levels of lead on school playgrounds, but most are never tested. Some of the toxins in rubber tire crumb include VOC's, PAH's, MBT's, and latex. The EPA has found these chemicals cause cancer, headaches, nausea, contact dermatitis, and allergies.
Artificial grass is allergen-free, so you can easily enjoy the great outdoors without the hay fever, sneezing, and watery eyes that accompany natural grass.
Want a better approach? Aggressively scrub the area clean with a disinfectant (chlorehexidine=GOOD, hydrogen peroxide=BAD) and then keep it clean, moist, and covered using Tegaderm or hydrogel.
How long do turf burns last?
They usually heal within 6 days without scarring the skin. Second-degree burns affect both the epidermis and the layer under the skin (the dermis). As well as pain and redness, people with second-degree burns may experience blisters. These burns may take 2 to 3 weeks to heal and are more likely to scar.
Turf Burn Treatment
Keep the wound completely dry by patting it dry with a clean towel. It is critical to remove all dirt and debris to avoid infection, even if it is very uncomfortable. Apply antibacterial cream to the affected area to avoid infection.
The turf industry maintains crumb rubber is safe. According to the Synthetic Turf Council, recycled tires are washed, and the dangerous chemicals are encased in the rubber. They cite several studies that conclude that recycled rubber infill...
It is estimated that 40,000 shredded waste tires are used to create the infill for just one artificial turf field! Therefore, it is important that the possible negative health ramifications associated with artificial turf's main component are considered.
Unfortunately, no. You must remove natural grass and all other organic matter, and lay a base before installing artificial turf on soil.

The league's operations page on uniform inspections gives a legitimate reason for eliminating dark visors in most situations: If a player suffers from migraines or is sensitive to sunlight, he'll need a medical exemption to put a tinted visor on his helmet as a replacement for the permitted clear visor.
Football visors have been around since the 1980s, but current rules made completely tinted visors illegal. In the NFL, players can wear dark tinted visors. In college and high school, dark tinted visors are illegal. All visors are at the referee and training staff's discretion whether or not they can be worn.
