molecular weight of pure white crystals, with a slight taste of mercaptan; 2.52mPa vapor pressure (25 ° C); melting point 42.5 ~ 43 ° C; solubility : water-soluble and insoluble in most organic solvents; density : 1.398; Stability : in the acid medium stability, in alkaline medium easy decomposition; risk Marker 15 (hazardous materials from the food); main purpose : To broad-spectrum insecticide, miticide, in the volatile high. Applicable to control citrus, cotton, corn, apples, pears, rice, peanuts, soybeans, wheat and tea and other crops on the pests and mites

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous breathing.
health hazards : Medium organophosphate insecticide poisoning. Inhibit cholinesterase activity. Symptoms of poisoning are headache, dizziness, weakness, blurred vision, nausea, vomiting, restlessness. There were serious pulmonary edema, incontinence, coma.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀145mg/kg (rat oral); 202mg/kg (rats Paper); 1000 ~ 2000mg/kg (rabbit oral); 32mg/kg (Chicken by mouth)
chlorpyrifos right bees have high toxicity, the eyes a slight stimulus, shrimp and fish toxic.
aquatic organisms forbearance limited degree (48 hours) : Carp to 0.13ppm, ADI for 0.001mg/kg.

hazardous characteristics : case of fire, combustible high fever. Decomposition by high fever and emit toxic smoke.
combustion (decomposition) products : carbon monoxide, carbon dioxide, nitrogen, nitrogen compounds, sulfur, phosphorus oxide.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography
"Solid Waste Analysis Evaluation Manual," the China Environmental Monitoring terminus translated

5. Environmental standards :
American plant health standards 0.2mg/m3 (skin)
maximum allowable residues : recuperates for citrus, cotton seed and cotton seed oil to 0.05ppm, Rice 0 .1 ppm, cabbage, lettuce to 0.1ppm.

6. Emergency treatment and disposal methods :
fire : firefighters are required to wear gas masks, body wear firefighting suits. Using dry powder, sand, foam and carbon dioxide fire extinguishers desert fire.

first aid and prevention : skin, eye contact, rinse water, wear protective clothing and wearing protective glasses.

Leakage : rapid withdrawal from air leakage, strictly limiting 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.
