TPH concentrations have been measured in many items that can be found throughout nature including grass (14,000 mg/kg of TPH), pine needles (16,000 mg/kg of TPH), and oak leaves (18,000 mg/kg). It has also been measured in petroleum jelly at concentrations of 749,000 mg/kg. Although these TPH concentrations are substantially
