Evaluating and regulating lead in synthetic turf

Area of Science:

• Environmental Health
• Toxicology
• Public Health

Background:

• A 2007 incident revealed lead in synthetic turf fibers and dust, exceeding hazard criteria.
• This prompted widespread testing of synthetic turf for lead exposure risks nationwide.
• Current lack of standardized methods hinders accurate lead hazard assessment in synthetic turf.

Purpose of the Study:

• Raise awareness of potential lead exposure from synthetic turf.
• Identify uncertainties in current risk assessment methodologies.
• Recommend federal/state agencies develop standardized lead assessment methods for synthetic turf.

Main Methods:

• Analysis of lead concentrations in synthetic turf fibers and dust from recreational fields and child care centers.
• Comparison of detected lead levels against established regulatory limits (CPSIA, EPA).

Main Results:

• Lead concentrations in synthetic turf fibers and dust exceeded the Consumer Product Safety Improvement Act of 2008 limit (300 mg/kg).
• Lead levels in dust surpassed the U.S. Environmental Protection Agency's hazard standard (40 µg/ft²).

Conclusions:

• Deteriorating synthetic turf can create lead-containing dust, posing risks to children.
• A consistent, nationwide approach for sampling, assessment, and action regarding synthetic turf lead is crucial.
• An interim approach is provided for assessing potential lead hazards in synthetic turf in the absence of standardized methods.
