Biooplaticide monga Azadirachtin ndi Pyrethrins amaphatikizidwa kwambiri. Ngakhale zinthu izi zimatengedwa ku mbewu zachilengedwe zimafotokozedwa kuti ndi "zoopsa zochepa," kupopera mbewu mankhwalawa kumatha kuyambitsa zotsalira. Chodetsa nkhawa kwambiri ndikuti miyezo yotsimikizika imakhazikitsa mitsinje ya nthaka ya 36, ​​koma ma mestphoosate metabolites am'mimba atha kupezeka m'madzi ena ku North China.

Milandu yachlorpyrifoschotsalira pakuyesa malipoti ndi chenjezo. Bamu imodzi yotsimikizika, yoyandikana ndi minda yachikhalidwe, idadwala matenda osokoneza bongo nthawi yanyengo yamvula, yomwe imayambitsa kupezeka kwa 0.02 mg / kg ya Ergepophorus Reremieus Sapiden. "Kupimitsa Mwapamwamba kumeneku" kumapangitsa kuti pakhale kothetsa dongosolo la chitsimikizo cha chitsimikizo chomwe chilipo mwa kuwunikira malo olima, kung'amba kung'ambika mu chiyero cha ulimi wa zachilengedwe.

Ii. Choonadi chowonetsedwa mu laborties

Mukamagwiritsa ntchito ma chromatotography - misa spectry, matesani amakhazikitsa malire a zitsanzo pa 0,001 mg / kg mulingo wa maki. Zambiri zimawonetsa kuti 90% ya zitsanzo zabwino zidali ndi zotsalira zokhazokha 1/50 mpaka 1/17 Komabe, kupitidelera kwaukadaulo kwamakono kwathandiza kugwidwa kwa mamolekyulu pama mamolekyulu amodzi, ndikupanga kwathunthu kwathunthu "zotsalira za ziro" ntchito yosatheka.

Kuvuta kwa maunyolo osadetsedwa ndi kulingalira. Zingwe zosungiramo zinthu zosungiramo zinthu zosakwanira za maakaunti a 42% yazomwe zimachitika, ndikulumikizana ndi kuipitsidwa ndi kuphatikizika kwa mashedissing masketor a 31%.

Iii. Njira Yothandiza Kumanganso Kukhulupirira

Kukumana ndi Lipoti la Kuyesedwa, mlimi wopangidwa bwino adawonetsa "makina osinthika" Njira imeneyi yokhazikitsa njira zopangira poyera ndikumanganso chidaliro chogula.

Akatswiri otetezedwa a chakudya amalimbikitsa kuti athe kutsata njira yotsukira " Njirazi zimatha kuchotsa 97,6% ya zotsalira, ndikupangitsa kuti chitetezo chathanzi chikhale cholimba.

Zambiri zoyesera labotale siziyenera kukhala umboni wokana mtengo wa ulimi wambiri. Tikayerekezera 0,008 mg / kg ya chlorpyrifos yotsalira ndi 1.2 mg / kg yomwe yapezeka mu Mlandu wa Msewu, titha kuwonabe luso lalikulu la machitidwe opanga organiction omwe amagwiritsa ntchito mankhwala osokoneza bongo. Mwina ungwiro weniweni sunama mu zero, koma mosalekeza kwa zero, zomwe zimafuna opanga, oyang'anira, ndi ogula kuti aletse maukonde abwino kwambiri.
