D008; A solid waste containing lead (such as diethyldimethyllead) 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.

Diethyldimethyl lead was detected in exhaust gas from a Ford Transit 2.0 ranging from 0.05-13.17 ug/cu m and from a Ford Escort 1.1 ranging from <0.01-4.58 ug/cu m(1). The highest concentrations occurred when the vehicles were stationary and choked(1). The Ford Transit 2.0 was run on gasoline containing 18.3 mg/cu dm of diethyldimethyl lead while the Ford Escort 1.1 was run on gasoline containing 24.6 mg/cu dm of diethyldimethyl lead(1). Levels of diethyldimethyl lead in vehicle exhaust gas samples measured in the United States during 1977 were <0.5 to 107 ng Pb/cu m(2).

SEDIMENT: Diethyldimethyl lead was not detected in sediment samples from Ontario, Canada in 1984 (detection limit 15 ng/g)(1). It was not detected in sediment samples from Colchester, U.K. in 1986 (detection limit 0.04 ng/g)(1).

Diethyldimethyl lead was detected in urban air samples in Antwerp, Belgium in 1980 ranging from <0.2-1.6 ng/cu m(1). It was also detected in urban air samples from Lancaster, U.K. in 1985 at concentrations ranging from 1.7-3.0 ng/cu m(1). It was detected in urban air samples from Colchester, U.K. in 1986 at concentrations ranging from <0.3-1.6(1). It was not detected in suburban air samples from Colchester, U.K. in 1986 (detetion limit 0.3 ng/cu m)(1).

It was not detected in urban and suburban aerosol particles in Colchester, U.K. and Bantry Bay, Ireland in 1986 (detection limit 0.22 pg/cu m)(1). Diethyldimethyl lead was not detected in a survey of urban and rural air samples from Beijing in late August 1980 (detection limit 0.2 ng/cu m)(3). During this time, China's population did not use very much leaded gasoline(3).|INDOOR: The concentration of diethyldimethyl lead measured in the air of a laboratory in Baltimore, Maryland during 1977 was 4 ng Pb/cu m(1).|RURAL/REMOTE: Diethyldimethyl lead was not detected in rural air samples from Lancaster, U.K. in 1985 (detection limit 0.3 ng/cu m)(1). It was not detected in rural air samples from Bantry Bay, Ireland in 1986 (detection limit 0.02 ng/cu m)(1). Diethyldimethyl lead was not detected in rural aerosol particles from Lancaster, U.K. in 1985 (detection limit 2 pg/cu m)(1). Diethyldimethyl lead was not detected in rural aerosol particles from Bantry Bay, Ireland in 1986 (detection limit <0.02)(1).|SOURCE DOMINATED: The concentrations of diethyldimethyl lead measured in air at various locations in Baltimore, Maryland during 1977 were 11-16 ng Pb/cu m in a automobile tunnel and 0.5-3 ng Pb/cu m by a highway,(1). Urban air was sampled on a busy town center street in Lancaster, U.K.(2). Samples were level with motor car exhaust 1.5 m from the curb of the road(2). Diethyldimethyl lead was detected in air samples during a 24 sampling period at concentrations ranging from 1700-3000 pg/cu m(2). It was also detected in aerosol samples during a 24 hr sampling period at concentrations ranging from 9-129 pg/cu m(2). Air sampled 3 meters above the ground and 5 meters from a relatively busy urban street (College St., Toronto) contained diethyldimethyl lead at 2 ng/cu m(3).

Diethyldimethyl 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 diethyldimethyl lead)(3). Sludge accumulating in the bottom of gasoline storage tanks is an important source of tetraalkyl lead compounds in the environment via cleaning, improper disposal and leakage from abandoned underground tanks(1).

TERRESTRIAL FATE: Organic matter in the soil will influence diethyldimethyl 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). Volatilization of diethyldimethyl lead from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.46 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Diethyldimethyl lead is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 2.2 mm Hg(2). However, adsorption to soil is expected to attenuate volatilization(SRC). Biodegradation data were not available(SRC, 2008).|AQUATIC FATE: Organic matter in the suspended solids and sediment may influence diethyldimethyl lead's mobility(1). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 0.47 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 5 hours and 6.8 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 690(SRC), from its its log Kow of 4.04(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Diethyldimethyl 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(8,9). 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), diethyldimethyl lead, which has an estimated vapor pressure of 2.2 mm Hg at 20 d(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase diethyldimethyl 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 14 hours(SRC), calculated from its rate constant of 2.8X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Diethyldimethyl 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 diethyldimethyl lead with photochemically-produced hydroxyl radicals has been estimated as 2.8X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 14 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Diethyldimethyl 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). Diethyldimethyl 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 alkyl lead compounds decompose fairly rapidly in the environment to the more stable tri-alkyl lead species(5).

An estimated BCF of 690 was calculated in fish for diethyldimethyl lead(SRC), using a log Kow of 4.04(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).

Organic matter in the soil will influence diethyldimethyl 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 diethyldimethyl lead is estimated as 0.47 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that diethyldimethyl 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 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 6.8 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is about 40 days when adsorption is considered. Diethyldimethyl lead's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Diethyldimethyl lead is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 2.2 mm Hg(3).
