| RCRA 要件 | P018As stipulated in 40 CFR 261.33, when brucine, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to federal and/or state hazardous waste regulations. Also defined as a hazardous waste is any container or inner liner used to hold this waste or any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5(e)). |

| 清掃方法 | 1. Ventilate area of spill. 2. Collect spilled material in the most convenient and safe manner and deposit in sealed containers for reclamation, or for disposal in a secured sanitary landfill. Liquid containing strychnine should be absorbed in vermiculite, dry sand, earth, or a similar material. /Strychnine/Pour into sodium bicarbonate or a mixture of sand-soda ash (9:1). After mixing, transfer into a paper carton filled with packing paper. Burn in an open furnace, or more efficiently in the furnace with afterburner and scrubber.Environmental considerations - Land spill. Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. /Strychnine/Environmental considerations - Water spillUse natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. If dissolved, in region of 10 ppm or greater concn, apply activated carbon at ten times the spilled amount. Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. /Strychnine/Spread over with 9:1 mixture of sand and soda ash. After mixing, transfer into a paper carton, stuffed with ruffled paper. Burn in an open furnace with the utmost care or in the furnace with afterburner and scrubber. |

| Treatment | Treatment of brucine poisoning involves an oral application of an activated charcoal infusion to absorb any poison within the digestive tract that has not yet been absorbed into the blood. Anticonvulsants such as phenobarbital or diazepam are administered to control convulsions, along with muscle relaxants such as dantrolene to combat muscle rigidity. (L1228) |

| 環境中動態 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 81(SRC), determined from a structure estimation method(2), indicates that brucine is expected to have high mobility in soil(SRC). However, the ability of brucine to adsorb to sediments and soil can not be predicted with certainty since this compound may act markedly different than its estimated Koc value indicates(SRC). Volatilization of brucine from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.1X10-16 atm-cu m/mole(SRC) using a fragment constant estimation method(3). Brucine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.0X10-10 mm Hg(SRC), determined from a fragment constant method(4). Half-life data for brucine indicate that biodegradation in soil may occur(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 81(SRC), determined from a structure estimation method(2), indicates that brucine is not expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 2.1X10-16 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). A pKa of 8.28 indicates brucine will exist almost entirely in the ionized form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process. According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(6) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low.ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), brucine, which has an estimated vapor pressure of 1.0X10-10 mm Hg at 25 °C(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase brucine may be removed from the air by direct photolysis and dry deposition(SRC). |

| Soil Adsorption/Mobility | Using a structure estimation method based on molecular connectivity indices(1), the Koc for brucine can be estimated to be 81(SRC). According to a classification scheme(2), this estimated Koc value suggests that brucine is expected to have high mobility in soil. The pKa of brucine is 8.28(3) indicating that this compound will exist in the protonated form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts. Volatilization from moist soil surfaces is not expected to be an important fate process because the cation is not expected to volatilize. Therefore, the ability of brucine to adsorb to sediments an soil cannot be predicted with certainty since this compound may act markedly different than its estimated Koc value indicates(SRC). |
