277.14

molecular weight of pure white crystals, crude oil for the tan, oily liquid, micro-a garlic smell; 0.80mPa vapor pressure (20 ° C); melting point 0. 3 ° C; the boiling point of 140 ~ 145 ° C / 13.3Pa; solubility : not soluble in water (D 0.98mg / L), but the majority of soluble organic solvent. The aliphatic hydrocarbons of low solubility; Density : 1.3227; Stability : alkaline hydrolysis case, in 30 ° C, sodium hydroxide 0.01mol the half-life of 272min, distillation will cause isomerization; Risk Marker 14 (drugs), 34 (flammable liquids); Main purpose : To tag insecticides to rice Pink Borer, Chilo suppressalis, three Borer, a rice leafroller effects

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : human oral dose to the minimum poisoning 800mg. Poisoning nausea, vomiting, diarrhea and difficulty in breathing. Acute poisoning performance of headache, dizziness, nausea, vomiting, abdominal pain, diarrhea, salivation, etc.. Severe poisoning were to pulmonary edema. Such a coma.

two, toxicology information and environmental behavior

toxicity : is low toxicity category.
acute toxicity : LD₅₀250mg/kg (rat oral); LD₅₀700mg/kg (rats Paper); Dog oral 40mg/kg / day x 98 days there is an obvious response poisoning; carp LC₅₀8.2mg/L, 48 hours.
subacute and chronic toxicity : rat oral 160ppm × 80 ~ 16 weeks, cholinesterase activity is markedly lower.
aquatic organisms forbearance limited degree (48 hours) : Carp to 8.2ppm.
fenitrothion toxicity to fish belong to the middle class, the frog nontoxic, highly toxic to bees.

metabolism and degradation : fenitrothion is characterized by movement in the soil faster, as hydrolysis or microbial role in the conversion to non-toxic amino fenitrothion. General application of 10 days is no longer found on its existence.

residues and accumulation : fenitrothion metabolism and the degradation of speed, so accumulation is not strong, but because of Rogor and to a certain extent within the same aspiration, it is the middle residual period (similar to DDVP).

migration and transformation : fenitrothion dissolved by the leaching of soil deeper role to the role nor the transfer, under natural conditions, the distance of 35 cm mobile, fenitrothion by the gastrointestinal tract and skin absorption on the surface, the machine in animal metabolism quickly, with the discharge of urine and feces, Therefore, fenitrothion not with the food chain transfers.

hazardous characteristics : case of fire, combustible high fever. With strong oxidant may react. Heating decomposition and emit nitrogen, phosphorus oxides and other toxic gases.
combustion (decomposition) products : carbon monoxide, carbon dioxide, phosphorus oxide, nitric oxide.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography
(GB/T14552-93, water and soil)
Gas chromatography (GB/T5009.20-1996, food)
GC (crops, fruits, vegetables), "Pesticide Residues GC" national commodity inspection bureau series

5. Environmental standards :
China (TJ36-79) Workshop harmful substances in the air that the maximum allowable concentration 1mg/m3 (skin)
the former Soviet Union (1977) Ambient Air maximum allowable concentration of 0. 005mg/m3 (a value)
0.001mg/m3 (days average)
the former Soviet Union (1977) surface highest allowable concentration of 0.25 mg / L
the former Soviet Union (1977) fishery waters the highest concentration of ABA / L
China (GB4788-94) in food organophosphorus pesticide standards allow 5mg/kg (WFP)

6. Emergency treatment and disposal methods :
a leakage contingency

rapid withdrawal leak contaminated areas, and strictly limit access. Cut off the fire source and not direct contact with the spill. A small leak : sand or other materials Unburning adsorption or absorption. Large leak : to build a causeway or trenching asylum; Foam coverage, lower vapor disasters. With the transfer pump to tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites. If solid, with clean shovel collection in a dry, clean, covered containers. If a large number of spills, recycling or collection shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : production operation or agricultural use, wear protective masks. Emergency rescue or escape, they should wear self-contained breathing apparatus.
eye protection : to use safety masks.
protective clothes : wear appropriate protective clothing.
hand protection : Wear protective gloves.
other : work site prohibit smoking, eating and drinking. After work, take a shower. Separate storage of toxic pollution by the clothes, washed reuse.

three, and emergency measures

acute poisoning, the patients immediately from the scene and contaminated clothes off, the body parts of contaminated with soap or alkali solution thorough cleansing, in the case of oral administration, application of 2% sodium bicarbonate or dilute brine gastric lavage, eye pollution can of soda water or saline irrigation.

Fire : sand, foam and carbon dioxide fire extinguishers, should wear reliable anti-virus, medical supplies and protective gear to prevent physical poisoning.
