Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Methyltriethyllead is included on this list.

D008; A waste containing lead (such as methyltriethyllead) may or may not be characterized as a hazardous waste following testing by the Toxicity Characteristic Leaching Procedure as prescribed by the Resource Conservation and Recovery Act (RCRA) regulations.

D008; A solid waste containing lead (such as methyltriethyllead) may or may not become characterized as a hazardous waste when subjected to the Toxicity Characteristic Leaching Procedure listed in 40 CFR 261.24, and if so characterized, must be managed as a hazardous waste.

Methyltriethyl lead was detected in exhaust gas from a Ford Transit 2.0 decimeter engine capacity ranging from 0.09-5.41 ug/cu m and from a Ford Escort 1.1 decimeter engine capacity ranging from 0.26-2.04 ug/cu m(1). The highest concentrations occurred when the vehicle was stationary and choked(1). The Ford Transit 2.0 was run on gasoline containing 15.4 mg/cu decimeter of methyltriethyl lead while the Ford Escort 1.1 was run on gasoline containing 9.1 mg/cu decimeter of methyltriethyl lead(1). The concentration of methyltriethyl lead in a runoff sample collected from an underground drainage culvert at a gasoline station was reported to be <0.3 ng Pb/L(2).

SEDIMENT: Reported concentrations of methyltriethyl lead measured in sediment collected from different locations in Ontario, Canada between 1979 and 1984 ranged from <0.5-142 ng Pb/g(1-3). Methyltriethyl lead levels were below 0.06 ng Pb/g in sediment collected from Colchester, UK in 1986(1). Analysis of roadside dust, roadside soil and sediment from various locations in England for alkylleads found methyltriethyl lead concentrations varying from below detection limits (0.06 ng Pb/g) to 38 ng Pb/g(4).

URBAN/SUBURBAN: The mean concentration of methyltriethyl lead measured in 6 air samples from Baltimore, MD during 1977 was 0.15 parts per trillion(1). Methyltriethyl lead was detected in urban air samples from Toronto, Canada in 1979 at 1 ng/cu m(2). Methyltriethyl lead was detected in urban air samples in Antwerp, Belgium in 1980 at concentrations ranging from <0.2-0.8 ng/cu m(2). The reported levels of methyltriethyl lead measured in urban air samples from Lancaster, U.K., Colchester, U.K., and Bantry Bay, Ireland during 1985-1986 were 0.9-2.5, <0.5-3.3, and <0.03 ng Pb/cu m, respectively(2). The reported levels of methyltriethyl lead measured in urban aerosol particles sampled from these three locations were 5-118, <0.3, and <0.03 pg Pb/cu m, respectively(2). Methyltriethyl lead was not detected in a survey of urban air samples from Beijing, China in late Aug 1980 (detection limit = 0.2 ng/cu m)(3). During this time, China's population did not use very much leaded gasoline(3). The concentration of methyltriethyl lead measured between September 1995 and May 1996 in the air of Bordeaux, France ranged from 0-3.1 ng/cu m(4).|INDOOR: Methyltriethyl lead was detected in air samples from a laboratory in Baltimore, MD in 1978 at 2 ng/cu m(1).|RURAL/REMOTE: Reported levels of methyltriethyl lead measured in air samples collected in England and Ireland during 1985-86 were <0.3 ng Pb/cu m in rural air and <0.5-1.2 ng Pb/cu m in semirural air(1). Methyltriethyl lead levels in atmospheric aerosols collected in England and Ireland during 1985-86 were <2 pg Pb/cu m (rural) and <0.3 ng Pb/cu m (semirural)(1). Methyltriethyl lead was not detected in rural air samples from near Beijing, China in late Aug 1980 (detection limit = 0.2 ng/cu m)(2).|SOURCE DOMINATED: Air sampled 3 meters above the ground and 5 meters from a relatively busy urban street (College St., Toronto) contained methyltriethyl lead at 1 ng/cu m(1). Methyltriethyl lead was detected in air samples from Baltimore, MD in 1978 at 1-6 ng/cu m in motor tunnel air, 1-4 ng/cu m in highway air, and <0.5-3 ng/cu m in vehicle exhaust(2). Urban air was sampled on a busy town center street in Lancaster, U.K.(3). Samples were level with motor car exhaust 1.5 m from the curb of the road(3). Methyltriethyl lead was detected in air samples during a 24 hour sampling period at concentrations ranging from 900-2,500 pg/cu m(3). It was also detected in aerosol samples during a 24 hr sampling period ranging from 5-118 pg/cu m(3).

Methyltriethyl lead's production and use as an anti-knock agent in fuels(1) may result in its release to the environment through various waste streams(SRC). The use of tetraalkyl lead additives in on-road automotive gasoline is no longer permitted in the United States; however tetraethyl lead is still used in leaded aviation gasoline(2). When burned, tetraethyl leaded fuels can produce other alkyllead compounds (such as methyltriethyl lead)(3).

TERRESTRIAL FATE: Organic matter in the soil will influence methyltriethyl lead's mobility because possibilities exist for inhibited mobility by sorption to soil organic matter and for enhanced mobility by the formation of soluble chelate complexes with soluble organic anions(1). However, during spills of leaded gasoline onto soils, the nonpolar nature of gasoline serves as a mobile solvent capable of transporting lead alkyl compounds through the soil(1). Volatilization of methyltriethyl lead from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.62 atm-cu m/mole(SRC), using a fragment constant estimation method(2). Methyltriethyl lead is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.3 mm Hg(SRC), determined from a fragment constant method(3). Biodegradation data were not available(SRC, 2008).|AQUATIC FATE: Organic matter in the suspended solids and sediment may influence methyltriethyl lead's mobility(1). Volatilization from water surfaces is expected(2) based upon an estimated Henry's Law constant of 0.62 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). Using this Henry's Law constant and an estimation method(2), volatilization half-lives for a model river and model lake are 5.1 hours and 7.0 days, respectively(SRC). According to a classification scheme(4), an estimated BCF of 480(SRC), from an estimated log Kow of 4.39(5) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Methyltriethyl lead is expected to undergo hydrolysis in the environment based on half-lives ranging from 14 hours to 8 days for the structurally similar substances tetraethyl lead and tetramethyl lead(7,8). Biodegradation data were not available(SRC, 2008).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), methyltriethyl lead, which has an estimated vapor pressure of 1.3 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase methyltriethyl lead is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 10 hours(SRC), calculated from its rate constant of 3.9X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Methyltriethyl lead is also expected to undergo direct photolysis in the environment based on half-lives ranging from 2.3-34 hours for the structurally similar substances tetramethyl and tetraethyl lead(4).

The rate constant for the vapor-phase reaction of methyltriethyl lead with photochemically-produced hydroxyl radicals has been estimated as 3.9X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 10 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Methyltriethyl lead is expected to hydrolyze in the environment based on its structural similarity to tetramethyl lead and tetraethyl lead which hydrolyze with measured rate constants of 1.83X10-6/sec and 1.33X10-5/sec, respectively, in seawater(2). These rate constants correspond to half-lives of 4.38 days and 14 hours, respectively(SRC). The hydrolysis half-life for tetraethyl lead measured in fresh water was reported to be 8 days(3). Methyltriethyl lead is also expected to undergo direct photolysis in the environment since both tetramethyl and tetraethyl lead undergo direct photolysis with measured rate constants of 1.4X10-3/min to 3.38X10-4/min and 5.1X10-3/min to 1.29X10-3/min, respectively(4). These rate constants correspond to half-lives of 8.3-34 hours and 2.3-9.0 hours, respectively(SRC). Laboratory studies indicate that tetra-alkyl lead compounds decompose fairly rapidly in the environment to the more stable tri-alkyl lead species(5).

An estimated BCF of 480 was calculated in fish for methyltriethyl lead(SRC), using an estimated log Kow of 4.39(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC). A study of a large spill of tetraalkyl lead compounds in the Adriatic Sea in 1974 revealed that these chemicals showed a relatively low level of accumulation by aquatic fauna(4).

Organic matter in the soil will influence methyltriethyl lead's mobility because possibilities exist for inhibited mobility by sorption to soil organic matter and for enhanced mobility by the formation of soluble chelate complexes with soluble organic anions(1). However, during spills of leaded gasoline onto soils, the nonpolar nature of gasoline serves as a mobile solvent capable of transporting lead alkyl compounds through the soil(1).

The Henry's Law constant for methyltriethyl lead is estimated as 0.62 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that methyltriethyl lead is expected to volatilize rapidly from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 5.1 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 7.0 days(SRC). Methyltriethyl lead's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Methyltriethyl lead is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.3 mm Hg(SRC), determined from a fragment constant method(3).

Methyltriethyl lead was also detected in sea water in the North Sea near Walton, Frinton, and Clacton, England at 0.15 ng/L, 0.14 ng/L, and 0.06 ng/L, respectively(2).|RAIN/SNOW/FOG: Methyltriethyl lead was detected at concentrations ranging from 8-27 ug/L in rainwater samples collected from semi-rural Lancaster, England between Nov 1983-March 1984(1). Methyltriethyl lead was not detected in semi-rural rainwater samples from Essex University collected between March 1985-March 86(1). Rainwater samples were collected from Lancaster, U.K. (rural and semirural), Cholchester, U.K. (urban and semirural), and Bantry Bay, Ireland (rural)(2). Reported concentrations in these samples were <3-15, <0.3, and <0.06 ng Pb/L, respectively(2). Methyltriethyl lead was detected in rainwater from rural and semi-rural Lancaster, U.K. in 1985 at concentrations ranging from <3-15 ng/L(2).

Alkyllead compounds were analyzed in road drainage water samples from the M6 motorway near Burton-in-Kendal, Cumbria U.K. collected during 7 storm events(3). Methyltriethyl lead was detected during two storm events at 11 and 18 ng/L(3).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 322 workers (0 of these were female) were potentially exposed to methyltriethyl lead in the US(1). Occupational exposure to methyltriethyllead may occur through inhalation and dermal contact with this compound at workplaces where methyltriethyllead is produced or used. Monitoring data indicate that the general population may be exposed to methyltriethyl lead via inhalation of ambient air and dermal contact with this compound or other products containing methyltriethyl lead, such as leaded gasoline(SRC).|The use of tetraalkyl lead additives in on-road automotive gasoline is no longer permitted in the United States; however tetraethyl lead is still used in leaded aviation gasoline(1). When burned, tetraethyl leaded fuels can produce other alkyllead compounds (such as methyltriethyl lead)(2).

Seven autopsy cases due to accidental tetraalkyllead poisoning are described. The victims died 5-19 days after poisoning. The highest lead concn was detected in the liver, spleen & kidney. Gas chromatographic analysis of oil tank contents responsible for the poisonings showed presence of methyltriethyllead. .

The concentration of lead in blood varies, in general, it is slightly elevated but in some cases of poisoning it is nearly normal. In cases of repeated gasoline sniffing the content of lead in blood is high. No close correlation exists between blood lead levels and the severity of intoxication.
