Freisetung ohne BrandSMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION. Then, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution.

STORE AWAY FROM SOURCES OF IGNITION. (NTP, 1992)
EntsorgungsverfahrenSRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations.Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced. Recommendable method: Incineration. Peer-review: Ensure plentiful supply of hydrocarbon fuel. (Peer-review conclusions of an IRPTC expert consultation (May 1985))Dissolve in a combustible solvent. Scatter the spray of the solvent into the furnace with afterburner and alkaline scrubber.
Verschüttetes entsorgenPersonal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Preventive MeasuresSRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.Condenser impregnation and other operations involving melting of chloronaphthalene should be enclosed or provided with effective local exhaust ventilation. /chloronaphthalenes/SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

UmweltverhaltenTERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 3,900(SRC), determined from a log Kow of 4.08(2) and a regression-derived equation(3), indicates that Halowax 1031 is expected to have slight mobility in soil(SRC). Volatilization of Halowax 1031 from moist soil surfaces may be an important fate process(SRC) given an estimated Henry's Law constant of 3.2X10-4 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Halowax 1031 is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.4X10-2 mm Hg(SRC), determined from a fragment constant method(5). Monochloronaphthalenes appear to be readily degradeable by soil and water microorganisms under aerobic conditions(6). No information was found on the biodegradation of higher chlorinated congeners by microorganisms(6)however, the addition of chlorines to aromatic structures is known to decrease biodegradability(7).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 3,900(SRC), determined from a log Kow of 4.08(2) and a regression-derived equation(3), indicates that Halowax 1031 is expected to adsorb to suspended solids and sediment(SRC). Halowax 1031 may volatilize from water surfaces(3) based upon an estimated Henry's Law constant of 3.2X10-4 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 7.3 hours and 6 days, respectively(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 60 days when adsorption is considered(5). According to a classification scheme(6), an estimated BCF of 280(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Monochloronaphthalenes appear to be readily degradeable by soil and water microorganisms under aerobic conditions(8). No information was found on the biodegradation of higher chlorinated congeners by microorganisms(8)however, the addition of chlorines to aromatic structures is known to decrease biodegradability(9).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), Halowax 1031, which has an estimated vapor pressure of 1.4X10-2 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 Halowax 1031 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 25 hours(SRC), calculated from its rate constant of 1.5X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 3000(SRC), determined from a structure estimation method(2), indicates that 1-chloronaphthalene is expected to have slight mobility in soil(SRC). Volatilization of 1-chloronaphthalene from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 3.55X10-4 atm-cu m/mole(3). However, adsorption to soil may attenuate this process. 1-Chloronaphthalene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.029 mm Hg(4). 1-Chloronaphthalene achieved 0% of its theoretical BOD in a screening test using sewage sludge(5)however, no biodegradation data were located for soil.AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 3000(SRC), determined from a structure estimation method(2), indicates that 1-chloronaphthalene is expected to adsorb to suspended solids and sediment(SRC).

However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 36 days if adsorption is considered(5). According to a classification scheme(6), measured BCF values in the range of 142-403 measured in fish(7), suggest bioconcentration in aquatic organisms is high(SRC). Halogenated aromatics are generally resistant to aqueous environmental hydrolysis(3)therefore, 1-chloronaphthalene is not expected to hydrolyze in water(SRC). 1-Chloronaphthalene achieved 0% of its theoretical BOD in a screening test using sewage sludge(7)however, no biodegradation data were located for water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-chloronaphthalene, which has a vapor pressure of 0.029 mm Hg at 25 °C(2), is expected to exist solely the vapor phase in the ambient atmosphere. Vapor-phase 1-chloronaphthalene 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 1 day(SRC), calculated from its rate constant of 1.5X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Laboratory exposure of an aqueous solution of 1-chloronaphthalene to light > 290 nm resulted in a photodegradation rate of 26% after 20 hrs of exposure(4).

Milk ConcentrationsAnalyses of breast milk from several hundred mothers collected from 1972 to 1992 in Sweden showed a decline in average concentrations of total PCNs from 3081 to 483 ng/kg lipid. For comparison, the corresponding values for the sum of PCDFs determined in the same breast milk samples were 132 and 30 ng/kg lipid, respectively. /Polychlorinated Naphthalenes/
ToxizitätsübersichtIDENTIFICATION: Halowax 1031 contains 95% monochlorinated naphthalenes and 5% dichloronaphthalenes. It has a 22% chlorine content. Halowax 1031 is insoluble in water. There are 75 possible congeners of chlorinated naphthalenes. Commercial products are generally mixtures of several congeners and range from thin liquids to hard waxes to high melting point solids. The higher chlorinated naphthalene products have been used as impregnants for condensers and capacitors and dipping encapsulating cmpd in electronic and automotive applications and as temporary binders in the manufacture of ceramic components, in paper coating and in precision casting of alloys, in electroplating, stop-off cmpd, as additive in gear oils and cutting cmpd, in flame proofing and insulation of electrical cable and conductors and moisture proof sealants, as separators in batteries, in refractive index testing oils, masking cmpd in electroplating and in grinding wheel lubricants. HUMAN EXPOSURE: The major sources of release of chlorinated naphthalenes into the environment are likely from waste incineration and disposal of items containing chlorinated naphthalenes to landfill. In the past, chlorinated naphthalene concn of up to 14.5 mg/cu m have been measured in the workplace, while levels of 25-2900 ng/cu m have been recorded in out door air in vicinity of manufacturing sites. More recently, monitoring studies have revealed chlorinated naphthalene concn up to 150 pg/cu m at semirural sites and 1-40 pg/cu m at remote sites. Chlorinated naphthalenes can be absorbed via oral, inhalative and dermal routes, with absorption and distribution over the whole body after oral admin. Chlorinated naphthalenes, especially the dioxin like congeners, have been detected in adipose tissue, liver, blood and breast milk samples from the general population at concn in the ng/kg lipid range. Severe skin reactions (chloracne) and liver disease have been reported after occupational exposure to chlorinated naphthalenes. ChIDENTIFICATION: There are 75 possible congeners of chlorinated naphthalenes. Commercial products are generally mixtures of several congeners and range from thin liquids to hard waxes to high melting point solids. Their main uses have been in cable insulation, wood preservation, engine oil additives, electroplating masking compounds, capacitors and refractive index testing oils and as a feedstock for dye production. HUMAN EXPOSURE: The major sources of release of chlorinated naphthalenes into the environment are likely from waste incineration and disposal of items containing chlorinated naphthalenes to landfill. In the past, chlorinated naphthalene concn of up to 14.5 mg/cu m have been measured in the workplace, while levels of 25-2900 ng/cu m have been recorded in out door air in vicinity of manufacturing sites. More recently, monitoring studies have revealed chlorinated naphthalene concn up to 150 pg/cu m at semirural sites and 1-40 pg/cu m at remote sites. A single study on chlorinated tap water revealed 0.44 ng monochloronaphthalene/l. Chlorinated naphthalenes can be absorbed via oral, inhalative and dermal routes, with absorption and distribution over the whole body after oral admin. Chlorinated naphthalenes, especially the dioxin-like congeners, have been detected in adipose tissue, liver, blood and breast milk samples from the general population at concn in the ng/kg lipid range. Severe skin reactions (chloracne) and liver disease have been reported after occupational exposure to chlorinated naphthalenes. Chloracne was common among workers who handling chlorinated naphthalenes in the 1930's to 1940's. A cohort study on workers exposed to chlorinated naphthalenes at a cable manufacturing plant found an excess of deaths from cirrhosis of the liver. However, individuals with chloracne did not show a higher mortality due to liver cirrhosis compared with other workers. The mortality from all cancers was slightly but significantly elevated among all exposed men (sta

Effluent ConcentrationsOrganic cmpd present at trace levels were extracted from fly ash samples collected from municipal incinerators in Japan, Canada, and the Netherlands. Chloronaphthalene, pentachloronaphthalene, and hexachloronaphthalene were found to be present in the fly ash samples. /Chloronaphthalenes/The investigators reported the detection of a large number of polychlorinated polynuclear aromatics, incl chlorinated naphthalenes, in flue gas samples from two coal-fired boilers and one municipal incinerator. Monochloronaphthalene, dichloronaphthalene, and trichloronaphthalene were some of the major polychlorinated polynuclear aromatics cmpd emitted from the tested boilers.Samples of leachate from a commercial coal tar were analyzed. Results showed that Halowax 1031 was identified in the coal tar leachate at concns unknown(1). Chemical species were extracted from trichloroethylene (TCE) soot generated from the combustion of TCE and methane. Halowax 1031 was detected in a 15.6 percent TCE mole fraction methane mixture at a concn of 43 ug/g soot. Halowax 1031 was detected in a 52 percent TCE mole fraction in methane mixture at a concn of 80 ng/g fuel in gas phase(2). Chlorinated organic compounds were detected during the combustion of propane in the presence of hydrochloric acid. Two components in Halowax 1031, identification and concns unknown, were detected(3). Analysis of sample extracts from modified method 5 from four different incineration test sites was conducted. Halowax 1031 was present in the forms of 1-chloronaphthalene at a concn of 10 ug/ml and 2-chloronaphthalene at a concn of 12 ug/ml. Halowax 1031 as a mixture was detected but not quantified(4). The thermolysis of chlorinated organics at different temperatures was conducted at various temperatures. Combustion of Halowax 1031 at 600 °C and 800 °C generated 2,4,5-trichlorophenoxyacetic acid, 2,4,5-trichlorophenoxyacetic ester, 2,4,5-trichlorophenol, 2,4,6-trichlorophenol, 2,4-dichlorophenoxyacetic acid, pentachlorophenol, alpha-hexachlorocyclohexane, and polychlorinated biphenyls(5). Total Halowax 1031 concn from the combustion of octachlorodibenzofuran in mineral oil was determined to be <5 ug(6).Samples were taken from a municipal waste site and compounds of waste gasification and combustion were identified. Crude gas samples had an average Halowax 1031 concn of 18,750 ng/N-cu mpurified gas samples had an average Halowax 1031 concn of 190,000 ng/N-cu memission flue gas samples had an average Halowax 1031 concn of 6,650 ng/N-cu m(1). Flue gas samples were taken from a 700 MW power station with circulating fluid bed combustion of coal in Flensburg, Germany.
