What is the next step in the Food Quality Protection Act?
EPA's next step under the Food Quality Protection Act (FQPA) is to consider the cumulative risks of all the OP pesticides, which share a common mechanism of toxicity. The interim decision on trichlorfon cannot be considered final until these cumulative risks are considered. Further risk mitigation may be required at that time.
Is trichlorfon a tred?
EPA has assessed the risks of trichlorfon and reached a decision presented in the "Report on FQPA Tolerance Reassessment Progress and Interim Risk Management Decision for Trichlorfon" (commonly known as a TRED) for this organophosphate (OP) pesticide. With the risk mitigation measures required, trichlorfon fits within its own "risk cup"; its individual, aggregate risks are within acceptable levels.

How is trichlorfon released into the atmosphere?
Trichlorfon's production and use as a veterinary medicine may result in its release to the environment through various waste streams ; it's use as an insecticide will result in its direct release to the environment. If released to air, a vapor pressure of 7.8X10-6 mm Hg at 20 °C indicates trichlorfon will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase trichlorfon will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2.5 days. Particulate-phase trichlorfon will be removed from the atmosphere by wet and dry deposition. Photodegradation of trichlorfon is slow and can result in the formation of another insecticide, dichlorvos. If released to soil, trichlorfon is expected to have high to very high mobility based upon reported Koc values of 6-79. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.2X10-11 atm-cu m/mole. Trichlorfon is not expected to volatilize from dry soil surfaces based upon its vapor pressure. The dissipation half-life for trichlorfon in soil is reported as <1-27 days. If released into water, trichlorfon may adsorb to suspended solids and sediment based upon the reported Koc values. Complete degradation of trichlorfon in aquatic environments occurs in <20 days. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's Henry's Law constant. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Trichlorfon is subject to hydrolysis with half-lives (22 °C) of 510 days (pH 4), 46 hours (pH 7), and <30 minutes (pH 9) being reported. Occupational exposure to trichlorfon may occur through inhalation and dermal contact with this compound at workplaces where trichlorfon is produced or used. Monitoring data indicate that the general population may be exposed to trichlorfon mainly via dermal contact where the pesticide is used, specifically at golf courses. Exposure can also occur through its medical administration. (SRC)

What are the white grubs?
White grubs (the larvae of various scarab beetles) are common pests of turf in the Northeast. Four species of grubs often cause problems in New England: the European chafer ( Rhizotrogus majalis ), the Japanese beetle ( Popillia japonica ), the oriental beetle ( Exomala orientalis ), and the Asiatic garden beetle ( Maladera castanea ). The life cycle of each of these species is relatively similar (adults fly in early summer and lay eggs in late June to late July; larvae feed on turf roots from early July through mid autumn and again in the spring; pupae are present in the soil for a week in mid June to mid July; and adults emerge early the following summer to complete the cycle). The life cycle of the European chafer occurs about two weeks earlier than that of the other species in any given location.
