molecular weight of the goods is (Z) and (E) isomer mixtures, the majority of them (Z) isomers, for amber oily liquid, (Z : E) isomers of the standard ratio 8.5:1; 0.00053Pa vapor pressure (20 ° C); the boiling point of 167 ~ 170 ° C (66.7Pa); melting point : -19 to -23 ° C; solubility : Micro-soluble in water, but with acetone, ethanol, kerosene, and xylene propanediol Compatibility; density : 1.36; Stability : This can be slow hydrolysis of water, steel, iron, brass, such as a corrosive effect, but the glass and polyethylene stability; risk Marker 14 (drugs); the main purposes : pesticides, soil treatment, can prevent cutworm, such as fly-

2. The impact on the environment :
toxicology information

acute toxicity : LD₅₀117mg/kg (mice by mouth); 20mg/kg (rat oral)

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography
reference to the "Handbook of Analytical Chemistry" (fourth volumes, chromatography analysis), the chemical industrial Press
GC (crops, fruits, vegetables), "Pesticide Residues GC" national commodity inspection bureau series

5. Environmental standards :
EEC regulations (1982) food maximum residue limits in general crops : 0.1mg; Specific crops : 0.05 to 0.5 mg / kg
the United States (1981) food and feed residue limits allow 0.005 ~ 3.2 (specific animal products)

6. Emergency treatment and disposal methods :
acute poisoning, the patients immediately from the scene and contaminated clothes off, the body parts of contaminated with soap or alkali solution thoroughly cleaned and, if oral, should be an immediate oral ~ 2% soda water , or 0.2 to 0.5% potassium permanganate solution gastric lavage, and taking drugs tablet PAM (PAM), or atropine 1 ~ 2. Eye pollution soda can or saline irrigation water.

leakage emergency : rapid withdrawal from air leakage personnel to a safe area, and strictly limit access. Cut off the fire source. Wear protective clothing. Cut off the source of leakage. A small leak with sand or other materials Unburning adsorption or absorption. Large amounts of water can drain Add Water diluted wastewater system. Large leak : to build a causeway or trenching asylum. Cover with lower vapor bubble disasters. With the transfer pump to tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites.

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