SECTION 9: Physical and chemical properties and safety characteristics
-
Physical state：
Naled is a white solid that may be dissolved in a liquid organic carrier with a pungent odor. It is a water emulsifiable liquid. It is insoluble in water and sinks in water. It can cause illness by inhalation, skin absorption and/or ingestion. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. If it is in liquid form, it can easily penetrate the soil and contaminate groundwater and nearby streams. It is used as a pesticide.

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on contact with acids and oxidants. This produces toxic and corrosive fumes including hydrogen bromide, hydrogen chloride and phosphorus oxides. Decomposes on contact with water. This produces dichlorvos and dichloroacetaldehyde. Attacks metals, plastics, rubber and coatings.
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.NALED is incompatible with the following: Strong oxidizers, acids, sunlight, water [Note: Corrosive to metals. Hydrolyzed in presence of water.] (NIOSH, 2016). Unstable in presence of Iron (USCG, 1999). Organophosphates 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

Persistence and degradability
AEROBIC: As a chemical class, the organophosphorus insecticides, such as naled, are generally considered to be biodegradable(1). The metabolism of naled in unsterile sandy loam was 3 times faster than in sterile sandy loam, and was 2-3 times faster than in sand, loam, and silt soils(2). The half-lives were 1.4 and 4 hours, respectively, for unsterile and sterile sandy loams. The half-lives for naled ranged from 2.6 to 4.0 hours for other soil types; DDVP was detected in all soil samples(2). The metabolism of 14C-labelled naled in Oakly sandy loam soil under aerobic conditions showed that degradation of naled to 14C-carbon dioxide was rapid with a half-life of 3 days(2). In a cranberry bog, the half-life for the aerobic metabolism of 14C-labelled naled was about 6 hours with most of the naled metabolized to carbon dioxide (71% in 30 days)(2).
Bioaccumulative potential
An estimated BCF of 0.4 was calculated for naled(SRC), using a log Kow of 1.38(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Koc values of 180(1) and 344(2) have been reported for naled. According to a classification scheme(3), these Koc values suggest that naled is expected to have moderate 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.
