I. "Aagga Cawlan" ee Heerarka Dabiiciga ah

Furitaanka "Sharciyada Hirgelinta Shahaadada Alaabta Dabiiciga ah," Qodobka 7aad ee cutubka 2aad wuxuu si cad u taxay 59 nooc oo sunta cayayaanka ah oo asal ahaan ka soo jeeda dhirta iyo macdanta loo oggol yahay isticmaalka. Daawooyinka biopesticides sida azadirachtin iyo pyrethrins ayaa si weyn loogu soo daray. Inkasta oo walxahan laga soo saaro dhirta dabiiciga ah lagu qeexay "sumoobid hoose", buufinta xad-dhaafka ah ayaa laga yaabaa inay weli keento hadhaaga. Walaaca ugu weyni waa in heerarka shahaadodu ay dejiyaan muddo sifaynta ciidda oo ah 36 bilood, laakiin dheef-shiid kiimikaadka glyphosate ee wareegyadii hore ee beeralayda ayaa wali laga ogaan karaa biyaha dhulka hoostiisa ee saldhigyada Waqooyiga Shiinaha.

Kiisaskachlorpyrifoshadhaaga warbixinnada imtixaanku waxay u adeegaan digniin ahaan. Hal saldhig oo shahaadad leh, oo ku dheggan dhul-beereed dhaqameed, ayaa la soo deristay wasakhowga sunta cayayaanka inta lagu jiro xilliga monsoon, taasoo keentay in la ogaado 0.02 mg/kg oo ah haraaga organophosphorus ee muunadaha isbinaajka. Tani "wasakhaynta dadban" waxay daaha ka qaadaysaa ku filnaansho la'aanta nidaamka shahaado bixinta ee si firfircoon ula socda deegaanka beeralayda, dildilaaca nadiifinta beeraha organic.

II. Xaqiiqda Lagu Daah-furay Shaybaadhka

Marka la isticmaalayo gaaska chromatography-mass spectrometry, farsamayaqaanadu waxay dejiyaan xadka lagu ogaanayo shaybaarada heerka 0.001 mg/kg. Xogtu waxay tusinaysaa in 90% muunadaha togan ay lahaayeen heerar hadha oo kaliya 1/50 ilaa 1/100 kuwa ku jira khudaarta caadiga ah, oo u dhiganta in lagu rido laba dhibcood oo khad ah barkadda dabaasha caadiga ah. Si kastaba ha ahaatee, horumarka tignoolajiyada casriga ah ee ogaanshaha ayaa suurtageliyay qabashada molecules ee heerka hal-bilyan, taasoo ka dhigaysa "haraad eber" hawl aan macquul ahayn.

Kakanaanta silsiladaha wasakhaysan waa ka baxsan male-awaalka. Wasakhda bakhaarka oo ay sabab u tahay baabuurta si aan dhamaystirnayn loo nadiifiyay ayaa 42% ka ah heerarka shilka, halka wasakhdaynta xidhiidhka ka dhashay meelaynta isku dhafan ee khaanadaha dukaamada waaweyn ay ka yihiin 31%. Si ka sii qarsoodi ah, antibiyootiga lagu qaso qaar ka mid ah bacriminta organic alaabta ceeriin ayaa ugu dambeyntii gala unugyada khudradda iyada oo loo marayo bioaccumulation.

III. Dariiq Caqli Ah Oo Dib Loogu Dhisayo Kalsoonida

Iyaga oo wajahaya warbixinta tijaabada, beeralayda dabiiciga ah ayaa soo bandhigay "nidaamka raadinta daahfurnaanta": Koodhka QR ee xirmo kasta waxa uu u ogolaanayaa in la waydiiyo saamiga Bordeaux isku darka ah ee la dabaqay iyo warbixinnada baaritaanka ciidda ee ku hareeraysan saddex kiilomitir. Habkan meelaynta hababka wax-soo-saarka ee bannaan ayaa ah dib-u-dhiska kalsoonida macaamiisha.

Khubarada badbaadada cuntadu waxay ku talinayaan in la qaato "hab sifaynta saddex-jibbaaran": ku qoonta biyaha soodhaha si ay u baabi'iyaan sunta cayayaanka dufanka ku milma, iyadoo la isticmaalayo nadiifiyaha ultrasonic si uu uga saaro xayaysiisyada dusha sare, iyo blanching 5 ilbiriqsi at 100 ° C si aan firfircoonayn enzymes noolaha. Hababkani waxay baabi'in karaan 97.6% hadhaaga raadraaca, taasoo ka dhigaysa khadka difaaca caafimaadka mid aad u adag.

Xogta shaybaadhka shaybaadhka waa inaanay u adeegin sidii xukun diidaya qiimaha beeralayda dabiiciga ah. Markaan is barbar dhigno 0.008 mg/kg ee haraaga chlorpyrifos iyo 1.2 mg/kg oo laga helay celery caadiga ah, waxaan wali arki karnaa waxtarka weyn ee hababka wax soo saarka dabiiciga ah si loo yareeyo isticmaalka sunta cayayaanka. Waxaa laga yaabaa in nadiifnimada dhabta ah aysan ku jirin eber dhammaystiran, laakiin si joogto ah u soo dhowaanaysa eber, taas oo u baahan soosaarayaasha, maamulayaasha, iyo macaamiisha si wadajir ah u duubaan shabakad tayo adag leh.
