Numerous studies exist on turf "off-gassing" carcinogenic effects -
We were in Lancaster over the scalding weekend and the air was chemically stifling over the field. Anyone have any more recent data regarding effects? The turf fields are horrendous in the summer and grass is not used - for saving them? for killing kids? for what???

VOC release from crumb rubber infill would be expected to be greatest under sunny, hot weather conditions and the surface of artificial fields is known to become hotter than the ambient air. Temperatures of 150F or higher have been found under these conditions (McNitt, 2007). Particle release is expected to be affected by the number of athletes using the field at any given time, their body weight and the intensity of their exercise. Weather conditions such as temperature gradients and wind will affect gas and particle concentrations in the breathing zone of athletes; in general this is 3-6 feet above the surface. Temperature studies done by Pennsylvania State University indicate the rapid dispersal of heat with height above the fields with measurements 3 feet above the surface 40-60F less than the surface temperature (McNitt, 2007). This rapid atmospheric mixing suggests that VOCs emanating from the surface will also rapidly dilute and that the main potential for exposure is during brief periods where athletes are lying flat on the ground. Indoor fields will have less dilution effect (less wind and temperature gradient) and measurements at indoor soccer fields in Norway (height above field not specified) found a variety of rubber-related VOCs (Dye, et al., 2006).
