ADEME (French Offc - Environment and Energy Mgmt)
Field Test Study of Water and Air Quality
Using Infilled Artificial Turf Fields
(9-2007)

ALIAPUR, the leading French government body responsible for used tires, along with ADEME, the French Agency for Environment and Energy Management has completed a scientific study that aimed at evaluating possible environmental impact from the rubber granules in sports fields that are derived from recycled used car tires.

The studies shows no cause for concern to human health.

The main goal of the study was to determine the quality of water transferred into the natural environment after passing through the rubber granules and other infill materials from the artificial grass sports fields. In addition, the study obtained a detailed analysis and evaluation of the gas emissions generated by these fields.

Initiated in 2005, this study was conducted with the scientific aim of replicating normal field usage conditions to properly evaluate any potential environmental impact from runoff water and the potential of any health risk from gaseous emissions.

Epidemiological studies conducted bvy the Health Effects Institute, The Whorld Health Organization and other investigators do not implicate tyre [tire] wear particles in ambient air as contributing to human health effects (respiratory and cardiovascular diseases).

"Preliminary Assessment of the Toxicity from Exposure to Crumb
Rubber: its use in Playgrounds and Artificial Turf Playing Fields
"
June 2007

Prepared By
Thomas Ledoux, Ph.D., Research Scientist
New Jersey Department of Environmental Protection
Division of Science, Research and Technology

Comments/Summary:
Insufficient information was found to perform a complete formal exposure assessment/risk characterization on crumb rubber for the stated outdoor use at this time due to existing data gaps in the available information. After reviewing the information available, with the possible exception of allergic reactions among individuals sensitized to latex, rubber and related products, there was no obvious toxicological concern raised that crumb rubber in its intended outdoor use on playgrounds and playing fields would cause adverse health effects in the normal population. < more >

EPA -
Basic Information on Recycled Tire Materials

At the end of 2003, the U.S. generated approximately 290 million scrap tires. Historically, these scrap tires took up space in landfills or provided breeding grounds for mosquitoes and rodents when stockpiled or illegally dumped. Fortunately, markets now exist for 80.4% of these scrap tires-up from 17% in 1990. These markets-both recycling and beneficial use-continue to grow. The remaining scrap tires are still stockpiled or landfilled, however.

In 2003, markets for scrap tires were .... Continued => HERE

Comments/Summary:
The available body of research does not substantiate the assumption that cancer resulting from exposure to SBR granulate infills in artificial turf [systems] could potentiall occur.


Penn State University

A Survey of Microbial Populations in
Infilled Synthetic Turf Fields


Andrew S. McNitt , The Pennsylvania State University
Dianne Petrunak, The Pennsylvania State University
Thomas Serensits, The Pennsylvania State University

Results
The results of total microbial populations are shown in Table 1. While microbes exist in the infill media the number was low compared to natural turfgrass field soils. It should be remembered that microbes tend to be present on most surfaces humans come in contact with and the simple presence of microbes should not be cause for concern. In fact, many products on the market claim to boost the microbial populations of natural turfgrass soils with higher microbial populations considered to be beneficial.


Edmonton, Canada

Effect of Crumb Rubber Topdressing
on Athletic Fields:

Pilot Study - begun in 1997
D.K. Tompkins, J.B. Ross and D.L. Moroz

Introduction
A pilot study was established in 1997 on an athletic field in Edmonton (Austin O'Brien High School) to determine the effect of using crumb rubber topdressing.

Summary
A second application of crumb rubber did not negatively affect turf area cover, density or quality. The level of soil zinc temporarily increased. However, by the end of the season, there were only relatively small differences among the crumb rubber treatments. Also, the difference between soil zinc levels in the one and the two applications was minimal.

Birkholz, Belton, and Guidotti:

"Toxicological Evalutation for the Hazard Assessment of Tire Crumb for Use in Public Playgrounds "
July 2003

Comments/Summary:
No test was clearly genotoxic*. No tests performed without microsomal activation demonstrated genotoxic activity. Seven test tests were marginal after activation but did not meet the criteria for genotoxicity and are considered negative.

In all instances except one, the PEEP index was determined to be less than 3, which is considered acceptable by Environment Canada. In the case of the schoolyard material, which was freshly installed and kept in place for three months, the PEEP index was only marginally greater than 3 (3.2). With further aging in place or treatment before installation, this value should drop below 3.


* Genotoxic chemicals are those which are capable of causing damage to DNA.
Such damage can potentially lead to the formation of a malignant tumor, but DNA damage
does not lead inevitably to the creation of cancerous cells

ISA Sport Test Institute

Heavy Metals: Safety Study

"Study from ISA Sport test institute, the NOC/NSF and the KNVB"

Comments/Summary:
All heavy metal levels are in compliance with the standards applicable to toy manufacturing and the risk of harmful effects on sportsmen and women is therefore negligible. Indoor and outdoor use of rubber infill poses absolutely no risk to sportsmen/sportswomen or other parties concerned through inhalation..


Tun Abdul Razak Research Centre (UK):

2006

Comments/Summary:
Using the most severe extraction methodology, the nitrosamines found were only slightly above the detection level. These low levels of NDMA and N-MOR represent a worst-case scenario with regard to the product.

RIVM (Netherlands)
Leaching of zinc from rubber infill
on artificial turf (football pitches)

Authors: HERE

Summary/Abstract:
Human health risks posed by leaching of zinc are negligible as zinc concentrations in the water do not exceed drinking water standards. In the present study a targeted environmental risk assessment is performed for zinc in rubber infill on football pitches. The main focus was on the release of zinc from the rubber infill, i.e. the zinc load, the distribution of zinc between the soil, groundwater and surface water. Ageing of the rubber crumbs appears to be of major importance for estimating zinc releases.
