EntsorgungsverfahrenSRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity 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 and plant lifeand conformance with environmental and public health regulations.SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.Peer-review: This highly toxic material is rapidly hydrolyzed by cold alkali. Use 5 parts by volume 4% wt/vol sodium hydroxide soln to 1 volume of pesticide. Hydrolysis is improved by making the sodium hydroxide soln in 50% ethanol. Use much water to wash reaction mixture down to sewer. Large amt - incinerate in a unit with effluent gas scrubbing.

Preventive MeasuresA portion of even the most flammable materials is likely to be lost by vaporization. ... The smoke from an open fire used to destroy pesticides will contain some of the poison. Burning should be attempted only in an isolated place. Inhalation of smoke must be avoided. /Pesticides/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. The completeness of the cleaning procedures should be considered before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at the end of shift, but should remain at employee's place of work for cleaning.... Keep away from heat and open flame.Special aircraft should preferably be used for spraying or dusting toxic organophosphorus pesticides. ... Aerial spraying or dusting gives rise to clouds which spread over larger surfaces than clouds produced by ground application. Aerial spraying should therefore be carried out on windless days only. Residential areas, water supply sources, etc must be avoided. ... When aircraft approaches, signalmen /guiding the aircraft/ should leave the windward side. ... The local population should be informed about the site & time of aerial pesticide treatment. Access of unauthorized persons & especially children to the area to be treated must be ... forbidden. Warning signs should be placed at the limits of the area.

UmweltverhaltenTERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 170(SRC), determined from a structure estimation method(2), indicates that azinphos ethyl is expected to have moderate mobility in soil(SRC). Volatilization of azinphos ethyl from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 9.9X10-8 atm-cu m/mole(SRC), based upon its vapor pressure, 2.4X10-6 mm Hg(3), and water solubility, 10.5 mg/L(4). Azinphos ethyl is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Degradation of organophosphorothioate pesticides by photooxidation under ultraviolet or sunlight radiation at the soil surface may result in the formation of sulfoxides and trialkyl phosphorothioates(5). The methyl analogue, azinphos methyl, biodegraded in laboratory tests and in soil(6,7) which suggests that azinphos ethyl would also be degraded in the environment(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 170(SRC), determined from a structure estimation method(2), indicates that azinphos ethyl is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 9.9X10-8 atm-cu m/mole(SRC), derived from its vapor pressure, 2.4X10-6 mm Hg(4), and water solubility, 10.5 mg/L(5). According to a classification scheme(6), an estimated BCF of 80(SRC), from its log Kow of 3.40(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Hydrolysis half-life for azinphos ethyl was measured as 173 days at pH 6.1 and 22 °C(9). Photodegradation in aqueous environmental conditions is expected to be the most important process based on studies showing the half-life of azinphos ethyl in river water (pH 7.3) and in seawater (pH 8.1) was 9 and 11 days, respectively, when exposed to lightat 22 °C in the dark half-lives were 65 and 58 days, respectively(10).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), azinphos ethyl, which has a vapor pressure of 2.4X10-6 mm Hg at 20 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase azinphos ethyl 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 2 hours(SRC), calculated from its rate constant of 1.9X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase azinphos ethyl may be removed from the air by wet or dry deposition(SRC). Azinphos ethyl contains chromophores that absorb at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).
LebensmitteluntersuchungswerteAzinphos ethyl residues were not found on 13,960 food samples analyzed by state agencies in 6 states in 1988(1). Azinphos ethyl residue was detected on 6 of 13,085 (0.045%) samples of food analyzed by state agencies in 10 states in 1989(1). A small sample of the food analyzed was imported from Mexico, Central America, and the Caribbean(1) and since azinphos ethyl is not sold in the US, it is presumed that the residues were found on the imported food. Azinphos ethyl was detected in 20 pasta samples collected in Rome, Italy in 1990 at an average concentration of 0.9 ug/kg (range not detected to 4.5 ug/kg)(2). Azinphos ethyl was not detected (detection limit 0.05 mg/kg) in 10 ready-to-eat packed table olive samples or 30 commercially packed olive oil samples analyzed from 1991-1992 in Greece(3). Azinphos ethyl was detected 2 of 2223 fruit and vegetable samples at 0.05 to 1.00 mg/kg (positive detections were in cucumber and green bean), samples were collected from Brazilian Sao Paulo General Storage and Wholesale over the period of Jan 1994 to Dec 2001(4). Azinphos ethyl was not detected (detection limit 5 ug/kg) in 298 raw milk samples obtained directly from tank trucks during delivery at nine Italian dairy plants, sampling took place Oct 2004, Jan and May 2005(5).

Average Daily IntakeThe average dietary intake of azinphos ethyl for people living in Rome, Italy in 1990 was 0.03 ug/man/day(1). This was derived from the average dietary intake of pasta which had an average concentration of azinphos ethyl of 0.9 ug/kg(1).
Plant ConcentrationsAzinphos ethyl residues were not detected (detection limit 0.01 ppm) in whole grains, leaves, and stalks of rice plants at harvest time (day 120) that were treated with azinphos ethyl at 5, 15, 45, and 60 days after planting(1).
Animal ConcentrationsAzinphos ethyl was detected in 2% of honeybee samples at concentrations of 0.020 to 0.094 mg/kg, dead bee samples were collected in bags suspended under beehives (only worker bees were analyzed) in the district of Bologna, Italy(1).
Acute Toxicity LinkChemical: AZINPHOS-ETHYL
Medical SurveillanceWorkers handling & applying pesticides must undergo an annual medical examination at the beginning of each agricultural season. Contraindications /meaning further clinical evaluations/ for work with /organophosphorus pesticides/ are organic diseases of the central nervous system, mental disorders & epilepsy, pronounced endocrine & vegetative disorders, pulmonary tuberculosis, bronchial asthma, chronic respiratory diseases, cardiovascular diseases & circulatory disorders, gastrointestinal diseases (peptic ulcer), gastroenterocolitis, diseases of liver & kidneys, eye diseases (chronic conjunctivitis & keratitis). The blood cholinesterase activity must be determined before work starts. In the event of prolonged work periods, this activity should be determined at intervals of 3-4 days. Persons exhibiting a fall in cholinesterase activity of 25% or more must be transferred to other work where they are not exposed to organophosphorus pesticides until this activity is completely restored. Persons with initial signs of indisposition should /be protected from exposure from/ pesticides. /Organophosphorus pesticides/... Surveillance of workers could be carried out through measurement of blood or urinary levels of the cmpd to which they are exposed, or through measurement of a metabolite. /Organic phosphorus pesticides/The assessment of exposure to the organophosphate pesticides, bromophos and dicrotophos can be accomplished through measurement of these compounds in the blood. However, since organophosphate pesticides are rapidly cleared from the blood, it is difficult to be able to detect the pesticides in blood unless very large quantities have been absorbed. This test may be useful for identification of the compound in cases of severe exposure, although documented tests for measurement of specific organophosphate pesticides in blood are very limited. Whole Blood Reference Ranges: Normal - none detectedExposed - not establishedToxic -not established. Serum or Plasma Reference Ranges: Normal - not establishedToxic - not established. Urine Reference Ranges: Normal - not establishedToxic - not established. /Organophosphate pesticides/Pulmonary Function Tests: The tests that have been found to be practical for population monitoring include: Spirometry and expiratory flow-volume curvesDetermination of lung volumesDiffusing capacity for carbon monoxideSingle-breath nitrogen washoutInhalation challenge testsSerial measurements of peak expiratory flowExercise testing. /Organophosphate pesticides/For more Medical Surveillance (Complete) data for AZINPHOS ETHYL (7 total), please visit the HSDB record page.
Soil Adsorption/MobilityUsing a structure estimation method based on molecular connectivity indices(1), the Koc of azinphos ethyl can be estimated to be 170(SRC). According to a classification scheme(2), this estimated Koc value suggests that azinphos ethyl is expected to have moderate mobility in soil. Using a lysimeter to measure the leachability of various pesticides, azinphos ethyl was not detected in leachate from 3,000 individual analyses conducted from 1977-1986 (detection limit 0.001 mg/L)(3). These tests were conducted using 1-1.3 m in height by 0.5 sq m of top soil with a catch base of 1 sq m(3). For soil material, loamy or silty sand with a low humus content was used where the sum of clay and silt amounted to a maximum of 30% (clay below 10%) and the content of organic bound carbon did not exceed 1.5%(3).
