Mtengo Wamalonda Wothamangitsa Tizilombo Dimefluthrin

Mafotokozedwe Akatundu

pyrethroid Insecticide yomwe imakhala ndi mphamvu yolimbana ndi udzudzu ndi tizirombo tina.Dimefluthrin ndi yapamwamba kwambirimankhwala ophera tizilombo.Ndi madzi achikasu owala mpaka oderapo, osachokera ku zinthu zakunja, komanso ndi othandiza pa zofukiza zothamangitsa udzudzu.koloko ya udzudzuamagwiritsidwa ntchito kupha kapena kupha udzudzu, chifukwa mlingo wake ndi wochepa, choncho kuvulaza kwa munthuyo kumakhala kochepa.Public Health.

Kuzindikira zinthu
Gwiritsani ntchito chromatography ya gasi kusanthula zomwe zili mu tetrafluoromethrin.Kugwiritsa ntchito fenpropathrin monga muyezo wamkati, DB-1 quartz capillary column separation ndi kuzindikira kwa FID.Zotsatira zowunikira zikuwonetsa kuti mzere wolumikizirana wa tetrafluoromethyl ether Chemicalbook pyrethroid ndi 0.9991, kupatuka kokhazikika ndi 0.000049, koyenelera kosiyana ndi 0.31%, ndipo kuchira kuli pakati pa 97.00% ndi 99.44%.

Kusamala

Ngati chipinda amasuta ndi zofukiza udzudzu kwa nthawi yaitali ndipo mpweya kufalitsidwa si yosalala, zingachititse zizindikiro za chifuwa chomangira ndi chizungulire kwa amayi apakati, kuchepetsa pafupipafupi fetal kayendedwe, komanso chifukwa fetal hypoxia pamimba.Choncho, ndi bwino kuti amayi apakati asamagwiritse ntchito zida za udzudzu.
