1) Synthetic Tire Waste Fields

Contain Health Risks


HOME PAGE                                 

                 Natural grass fields use products that are tested and regulated. Tire crumbs are not tested or regulated. LIKE CIGARETTES, TIRES CONTAIN A MULTITUDE OF CARCINOGENIC AND TOXIC ADDITIVES that can pose immediate as well as delayed health risks. 

If the crumbs are accidentally ingested, they are digested and can release carcinogens. ONLY 10 GRAMS OF INGESTED TIRE CRUMBS PUTS YOU OVER THE RISK THRESHOLD FOR CANCER IN CALIFORNIA. No research has been done regarding the harmful effects on pets or wildlife ingesting tire crumbs.

                                                  Some of the health risks that playing in tire waste poses include exposure to; HEAVY TOXIC METALS, cadmium, lead, zinc polycyclic aromatic hydrocarbons or PAHs, VOCS - VOLATILE ORGANIC COMPOUNDS, gases such as toluene and benzothiazole, SILICA INHALATION,  and VIRULENT BACTERIA. Due to competitive interests, tire manufacturers of course will not, and are not required to disclose the exact amounts. Tires are not manufactured or sold to be ground up and spread in public recreation spaces .

  

                                                                                                                      Deteriorating tire waste becomes powdery and creates a dust of industrial chemicals. These are released into the air when kicked or stirred up by wind. Studies at tire reclamation sites document a spectrum of health effects ranging from SEVERE SKIN AND EYE IRRITATION AND RESPIRATORY IRRITATION AND THREE FORMS OF CANCER. Given the variety and types of chemicals involved, it is not surprising that some have toxic or carcinogenic activity when tested in laboratory animals.

A summary of the toxic actions of concern to researchers at Environment and Human Health Inc. as a result from exposure to tire crumbs include;

·        SEVERE IRRITATION OF THE RESPIRATORY SYSTEM;

·        SEVERE IRRITATION OF THE EYES, SKIN AND MUCOUS MEMBRANES;

·        SYSTEMIC EFFECTS ON THE LIVER AND KIDNEYS;

·        NEUROTOXIC RESPONSES;

·        ALLERGIC REACTIONS;

·        CANCERS;

·        AND DEVELOPMENTAL EFFECTS.

 

Additionally, caustic solvents are required to remove old bubblegum from the mesh. Other regular treatments used are algaecides, products to mask the odor, and various specialized cleansers.

                    

Athletes tend to suffer similar rates of injuries on synthetic turfs, (10 injuries per 1000 athletes), as on natural turfs, (7 per 1000), but different surfaces tend to result in different types of injuries. There is more torque, more velocity and more traction on artificial turf which lead more ACL (Anterior Cruciate Ligament injuries) and MORE MUSCLE STRAINS AND SPASMS.

Because artificial turf has a lower co-efficient of friction than natural grass, especially when wet, the athlete slides a considerably greater distance, thus generating heat and producing injury such as OPEN WOUND ABRASIONS, LACERATIONS, AND “BURNS” TO A MUCH GREATER EXTENT THAN NATURAL GRASS. These kind of wounds create sites of potential infection like MRSR (methicillin-resistant Staphylococcus aureus) "superbug".

Since the artificial field is a mesh covering sand like crumbs, mounds tend to form through impact and natural wind erosion. The pool table flatness becomes undulations. Some will be able to be mechanically rolled out, others will not.

 

TURF TOE, (metatarsalphalangeal joint sprain), is an injury associated with playing sports on artificial turf and is a common injury. It occurs when the cleats "grab" the turf and cause an overextension of the big toe. THE GRAB EFFECT ALSO HAPPENS WITH CRUTCHES AND WALKERS.

FOOTLOCK is caused when the plastic turf prevents the foot from turning which stresses the knees. Divots in natural grass are a sign that the lawn prevented this torque.

In "cloudy" San Francisco, on a 81-degree day, the field temperature at Silver Terrace field was measured to be 161-degrees. The black infill acts as a solar collector and CAN BECOME DANGEROUSLY HOT. A 98-degree day will produce a surface temperature on the synthetic grass of 173 degrees. Skin exposed to 160 degrees for only 1 second, can result in THIRD DEGREE BURNS. At Syracuse University, the turf melted the bottom stud on one of a player’s cleats. On a 98-degree day at “head-level height”, the thermometer registers 138 degrees. Heat exhaustion is commonplace. Dehydration must be closely monitored. Parents need to be warned.

Evidence suggests that artificial fields are a source of bacteria for the MRSA "superbug" staph infection (methicillin-resistant Staphylococcus aureus).

 

 

 

The antibiotic resistant bacterium has recently showed up in clusters with athletes that play on artificial turf. A tire waste field is completely made of synthetic material. Any organic material such as blood, vomit, spit, sweat, urine, or fecal matter becomes trapped within the tire crumbs. There it remains, and colonizes. Bacterial populations can double as quickly as every 10 minutes.

 

 

 

Instead of the soil safely breaking these materials down, the tire crumb layers will need to be thoroughly chemically disinfected on a regular basis. Superficial disinfectant is not enough.

Natural grass is again becoming the preferred surface for most professional and college sports teams. The University of Florida, University of Iowa, the Chicago Bears, and the New England Patriots, among others, have stated that REDUCING INJURIES WAS THE MAJOR REASON FOR CHANGING BACK TO GRASS.

 Ten new major league baseball stadiums completed between 1970 and 1990 all had synthetic surfaces. However, since 1991, 18 new major league baseball stadiums have been built, all with natural grass.
         The older stadiums have removed the synthetic turf, e.g., Candlestick Park, and today only 3 major league baseball stadiums with synthetic turf are in use, the Metrodome in Minneapolis (Minnesota Twins), Tropicana Field in St. Petersburg (Tampa Bay Rays) and Rogers Centre in Toronto (Toronto Blue Jays) with both the Metrodome and Tropicana Field to be replaced with new natural grass stadiums in the near future. Maintenance and injury are often cited, and most players simply prefer real grass.
       All 7 future ballparks currently in development will have natural grass: Cisco Field (Oaklands A's), Citi Field (New York Mets), Florida Marlins (Miami Ballpark), Nationals Park (Washington Nationals), Twins Ballpark (Minnesota Twins), Rays Ballpark (Tampa Bay Rays), and Yankee Stadium II (New York Yankees). It is clear that major league baseball has abandoned synthetic turf.
