Most important symptoms/effects, acute and delayed
This material is extremely toxic; the probable oral lethal dose for humans is 5-50 mg/kg, or between 7 drops and 1 teaspoonful for a 150 lb. person. It is a cholinesterase inhibitor which affects the nervous system. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Airway protection. Ensure that a clear airway exists. Intubate the patients and aspirate the secretions with a large-bore suction device if necessary. Administer oxygen by mechanically assisted pulmonary ventilation if respiration is depressed. Improve tissue oxygenation as much as possible before administering atropine, so as to minimize the risk of ventricular fibrillation. In severe poisonings, it may be necessary to support pulmonary ventilation mechanically for several days. Organophosphate pesticides
SECTION 5: Firefighting measures
Suitable extinguishing media
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, dry chemical or carbon dioxide.

SECTION 10: Stability and reactivity
Reactivity
Decomposes at room temperature. This produces flammable n-propylmercaptan (see ICSC 1492). Decomposes on heating. This produces toxic fumes including phosphorus oxides and sulfur oxides.
Chemical stability
Very stable in neutral and weakly acidic media. Rapidly hydrolysed in alkaline media. Stable in water up to 100 deg C at pH 7.
Possibility of hazardous reactions
Organothiophosphates, such as ETHOPROPHOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Conditions to avoid
no data available
Incompatible materials
Incompatible with alkaline materials.
Hazardous decomposition products
When heated to decomposition it emits very toxic fumes of /phosphorus oxides and sulfur oxides/.

Persistence and degradability
During ethoprop metabolism studies, it was observed that ethoprop did not metabolize in sterilized soils, but did in nonsterile soils(1). Soil from ethoprop treated plots in the Midwestern US were studied to determine ethoprop persistence(1); half-lives of 5-12 days were observed at application rates of 1-2 lb/acre granular formulation(1); when applied as a liquid formulation to VA soil, half-lives of 3-4 days were observed(1). Addition of ethoprop to soil has been observed to stimulate microbial oxygen consumption(2). During 4-week soil incubation studies using 1-ethyl-14C-labeled ethoprop, (14)CO2 evolution ranged from 23.4 to 50.9% in soils having no previous organophosphorus exposure and soils having prior exposure to isofenphos and fonophos(3); (14)CO2 from ethoprop was greater in soil having no prior exposure to the other pesticides(3). Mineralization of ethoprop was found to occur faster in soils that had been treated previously with ethoprop as compared to no prior treatment indicating microbial adaptation(4); during a 1 wk incubation, 32.7% mineralized in previously treated soil and 19.9% mineralized in untreated soil(4). Faster biodegradation in previously ethoprop treated soils was also noted in another study(5); sterilization of soils drastically reduced disappearance rates of ethoprop(5). The soil half-life of ethoprop can range from 3 to 56 days(6). In various field studies, soil half-lives of 2-12 weeks were determined(7). In soil column studies, ethoprop had the following half-lives(8): in silty loam (12 days at 20 deg C to 89 days at 2 deg C), in sandy loam (16 days at 20 deg C to 144 days at 2 deg C), in humous loamy sand (73 days at 20 deg C to 347 days at 6 deg C)(8). The half-lives of ethoprop in sterile and non-sterile soil from a banana plantation in Jamaica, with heavy ethoprop use, were 28.8 and 10.9 days, respectively(9).
Bioaccumulative potential
Using an intermittent flow-through system, an ethoprop BCF range of 4 to 17 was measured in juvenile sheepshead minnow over a 28 day exposure period(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
In adsorption studies using silty clay loam, silt loam and two sandy loam soils, ethoprop adsorption was found to increase as soil organic matter increased(1); adsorption was to a great extent reversible indicating that the major interaction between ethoprop and the adsorptive surfaces was hydrophobic bonding(1); experimentally determined Koc values (values not reported) place ethoprop in the medium soil mobility class(1). The US Dept Agric's Pesticide Properties Database lists a Koc value of 70 for ethoprop(2). Koc values of 120.6 and 76.0 have been reported for Riverhead and Rhinebeck soils, respectively(3). According to a classification scheme(4), these Koc values suggest that ethoprop is expected to have high mobility in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
