Kev tiv thaiv tshuaj lom Methyl parathion
Cov chaw tsim khoom thiab cov cuab yeej tsim khoom rau kev tsim khoom thiab ua tiav ntawm cov organic phosphorus sib txuas yuav tsum raug kaw kom tiv thaiv kev sib kis; kev tiv thaiv tus kheej yuav tsum tau them thaum tuav thiab txau tshuaj tua kab; hnav khaub ncaws hnav ntev, npog ntsej muag, kaus mom thiab hnab looj tes thaum ua haujlwm; Cais cia, txwv tsis pub sib xyaw cia nrog zaub mov, ntxiv dag zog rau kev tswj hwm thiab kev kawm. Thaum siv daim teb, nws yog qhov tsim nyog los ntxiv dag zog rau kev tiv thaiv daim tawv nqaij ntawm txhais tes thiab qis thib peb ntawm lub plab hlaub kom tiv thaiv kev ua qias tuaj thiab zam kev ua haujlwm qis. Tom qab daim ntawv thov, tos kom txog thaum cov ntsiab lus ntawm cov dej hauv thaj teb poob qis dua qhov muaj kev nyab xeeb ua ntej nkag mus rau hauv thaj av, feem ntau yog li 5 d. Ib qho ntxiv, teeb meem ntawm kev nyob lom yuav tsum tau tiv thaiv kom nquag. Qhov tso cai ntau tshaj plaws hauv cov qoob loo cog qoob loo tsim tawm txawv teb chaws yog 1 ppm. Cov khoom no muaj lub sijhawm nyob ntev, yog li tsuag nws rau cov zaub mov qoob loo ib hlis ua ntej sau qoob loo. Parathion tsis siv rau cov qoob loo luv luv ntawm cov zaub.
