| Entsorgungsverfahren | SRP: 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. |
| Verschüttetes entsorgen | Evacuate danger area! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. If liquid: collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. If solid: sweep spilled substance into containers. Carefully collect remainder. Then store and dispose of according to local regulations. |
| Preventive Measures | 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.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.... Should be used only in well ventilated premises and cumulative action of repeated small doses should be avoided.Inhalation of salt dusts should be avoided. /Hydrazine & derivatives/For more Preventive Measures (Complete) data for PHENYLHYDRAZINE (9 total), please visit the HSDB record page. |

| Wechselwirkungen | Erythrocytes (RBC) from phenylhydrazine treated mice are protective when injected into syngenic mice before x-ray irradiation. Evidence suggested that repair of hemopoietic stem cells was enhanced in mice injected with phenylhydrazine red blood cells before x-ray irradiation.The protective effect of phenylhydrazine hydrochloride (PHCL) against acute deaths resulting from whole body irradiation was examined in mice. Male (C3H/C57Bl)F1 mice received sc 1 mg PHCL in 0.1 mL water for 3 days. Controls received injections of water. Mice were injected ip with (59)iron as citrate 1 to 10 days after 3rd PHCL injection. Some mice were exposed to 800 roentgens at various intervals after 3rd injection. During the 1st five days, PHCL caused increases in spleen wt and (59)iron uptake in erthyrocytes and spleen, but a reduction in (59)iron uptake in femurs. All values returned to those of controls by 10 days after 3rd injection. Thirty-day survival of water injected control was 10%. Pretreatment with PHCL improved 30-day survival to almost 100% when mice were irradiated between 4 and 8 days after 3rd injection. Apparently the improved survival resulted from an increase in the number of hemopoietic stem cells at time of irradiation. /Phenylhydrazine hydrochloride/The peroxidation induced by phenylhydrazine in rats chronically exposed to lead was evaluated. Wistar-rats were exposed to lead in-utero and up to four months after birth via administration of distilled drinking water containing ...lead-acetate. The animals were then maintained in a closed desiccator system for analysis of exhaled hydrocarbons before or immediately after injection of phenylhydrazine. The effect of chronic lead pretreatment was assessed by measuring the production of the four main volatile hydrocarbons: ethane and pentane as indices of lipid peroxidationpropane as a marker of protein peroxidationand ethylene as an index of both lipid and protein peroxidations. Lead alone did not increase the physiological formation of alkanes. After phenylhydrazine injection, lipid peroxidation markers were not modified except for pentane in male lead treated rats. Ethylene and propane exhalation, on the other hand, were increased 45 minutes after phenylhydrazine injection in lead treated rats, indicating lead induced potentiation of the oxidative effect of phenylhydrazine. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 110(SRC), determined from a measured log Kow of 1.25(2) and a recommended regression-derived equation(3), indicates that phenylhydrazine will have high mobility in soil(SRC). Phenylhydrazine is a weak base with a pKa of 5.21(4), suggesting it will partially exist as a cation in moist soil, and the cationic form may adsorb to soil more than the free base(SRC). Phenylhydrazine is not expected to volatilize from moist soil surfaces(SRC)because cations do not volatilize and the Henry's Law constant of the free base is estimated as 2.9X10-8 atm-cu m/mole(SRC), calculated from experimental values for vapor pressure, 0.026 mm Hg(5), and water solubility, 1.27X10+5 mg/L(6). In the Zahn-Wellens aqueous screening test, 85% of this compound was biodegraded in 9-13 days(7). Phenylhydrazine may be susceptible to photolysis upon exposure to sunlight on soil surfaces as it strongly absorbs UV light in the environmentally significant range (wavelengths >290 nm)(8).AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 110(SRC), determined from a measured log Kow of 1.25(2) and a recommended regression-derived equation(3), indicates that phenylhydrazine should not adsorb to suspended solids and sediment in water(SRC). Phenylhydrazine is a weak base with a pKa of 5.21(4), suggesting it will partially exist as a cation in water, and the cationic form may adsorb to sediment more than the free base(SRC). Phenylhydrazine is not expected to volatilize from water surfaces(3)because cations do not volatilize and the Henry's Law constant of the free base is estimated as 2.9X10-8 atm-cu m/mole(SRC), calculated from experimental values for vapor pressure, 0.026 mm Hg(5), and water solubility, 1.27X10+5 mg/L(6). According to a classification scheme(7), an estimated BCF value of 2(SRC), from a measured log Kow(2) and regression derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Based on limited data, phenylhydrazine may biodegrade under aerobic conditions in natural water environments(SRC). In the Zahn-Wellens aqueous screening test, 85% of this compound was biodegraded in 9-13 days(9). Phenylhydrazine is not expected to undergo hydrolysis as it lacks hydrolyzable functional groups, but may be susceptible to photolysis upon exposure to sunlight in natural waters because it strongly absorbs UV light in the environmental UV spectrum (wavelengths >290 nm)(10).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), phenylhydrazine, which has a measured vapor pressure of 0.026 mm Hg at 25 °C(2), will exist solely as a vapor in the ambient atmosphere. Vapor-phase phenylhydrazine 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 about 9 hours(SRC), calculated from its rate constant of 4.3X10-11 cu cm/molecule-sec at 25 °C(SRC) estimated with a structure estimation method(3). |
| Unerwünschte Wirkungen | Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation. |
| Expositionspfade | The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.inhalation, skin absorption, ingestion, skin and/or eye contact |
| Toxizitätsübersicht | IDENTIFICATION: Phenylhydrazine exists as yellow to brown crystals or as a yellowish oily liquid. This chemical is used world wide mainly as a chemical intermediate in the pharmaceutical, agrochemical and chemical industries. HUMAN EXPOSURE: The number of persons potentially exposed to phenylhydrazine or its hydrochloride salt is unknown, but is expected to be small. No personal exposure data were available. There is evidence that phenylhydrazine has skin sensitizing properties in humans. There are no adequate data available regarding the reproductive or developmental effects, hence, it is not possible to evaluate the risk to human health for these endpoints. The level of risk in occupational settings is uncertainas a result, there is a continuing requirement to reduce exposure levels with the technology currently available. The lack of available data to serve as a basis for estimation of indirect exposure of individuals to phenylhydrazine from the general environment precludes the characterization of potential cancer risks for the general population. ANIMAL/PLANT STUDIES: The limited data on the toxicokinetics indicate that phenylhydrazine is well absorbed by inhalation, oral and dermal routes and binds readily with hemoglobin in red blood cells. Metabolism seems to occur via ring hydroxylation and conjugation, probably with glucuronic acid. Excretion is primarily via the urine. Phenylhydrazine is toxic by single exposure via the oral route (LD50 80-188 mg/kg body weight) and is expected to be toxic by inhalation and dermal routes (data from these routes are less clear). Phenylhydrazine has potential for skin and eye irritation. Exposure to this chemical may cause damage to red blood cells, potentially resulting in anemia and consequential secondary involvement of other tissues such as the spleen and liver. Phenylhydrazine is mutagenic in vitro, and there is some evidence to indicate that it may express genotoxic activity in vivo. The substance is clearly carcinogenic in mice following oral dosing, inducing tumors of the vascular system. Phenylhydrazine is readily biodegradable. Phenylhydrazine is toxic to aquatic organisms, with the lowest reported no observed effect concentration (NOEC) in standard acute fish tests at 0.01 mg/lfish are generally more sensitive than either daphnids or bacteria. A NOEC of 0.49 ug/l has been reported for embryo larval stages of the zebra fish (Brachydanio rerio). |
| Ökotoxizitätsauszüge | /AQUATIC SPECIES/ The toxicities of hydrazine and phenylhydrazine to embryos and larvae of zebrafish, Brachydanio rerio, were studied under standardized conditions. Exposures to the chemicals started at the blastula stage and the effect on hatching and survival were monitored for 15 days. The results showed that toxicities of phenylhydrazine to both embryos and larvae were more than those of hydrazine. The Lowest Observed Effect Concentration for hatching was 0.049 mg/L for hydrazine and 0.0078 mg/L for phenylhydrazine, the Lowest Observed Effects Concentration for survival of larvae was 0.0035 mg/L for hydrazine and 0.00098 mg/L for phenylhydrazine, respectively. The No Observed Effect Concentration for hatching was 0.0245 mg/L for hydrazine and 0.0039 mg/L for phenylhydrazine and the No Observed Effect Concentration for survival of larvae was 0.00175 mg/L for hydrazine and 0.00049 mg/L for phenylhydrazine, respectively./AQUATIC SPECIES/ In a study on the goldfish (Carassius auratus), 40% of fish died when exposed to phenylhydrazine at a nominal concentration of 1 mg/L for 48 h. Signs of toxicity included erratic swimming, sinking to the bottom of the test tank, and slowed and erratic respiration. No gross lesions were found following dissection, although all viscera showed focal hemorrhaging./AQUATIC SPECIES/ Effects on blood cells and the hematopoietic system, comparable to those found in mammals, were seen in fish injected with phenylhydrazine. Chinook salmon (Oncorhynchus tshawytscha) juveniles were injected with 12.5 mg phenylhydrazine/kg body weight. Red cell count, hemoglobin, and hematocrit fell to 1-5% of their normal values within 10 days of treatmenta slight improvement was reported 15 days following injection, and values had returned to normal 95 days after treatment. |
