Igama elithi "organic" lithwala okulindelwe okujulile kwabathengi ngokudla okumsulwa. Kepha lapho izinsimbi zokuhlola ilebhu zisebenza zisebenza, ingabe le mifino enamalebula aluhlaza ngempela njengengabonakali njengoba kucatshangwe? Umbiko wakamuva wokuqapha wekhwalithi wezwe emikhiqizweni yezolimo ye-organic eveza ukuthi phakathi kwamabhande angama-326 emifino ye-organic esampula, cishe ama-8.3% atholakale ukuthi athole umkhondoizinsalela ezihlanyisayo zokubulala izinambuzane. Le datha, njengetshe eliphonswe echibini, lenze ama-ripples emakethe yabathengi.
I. I "Grey Zone" yamazinga we-Organic
Ukuvula "Imithetho yokuqaliswa kwesitifiketi somkhiqizo we-organic," i-Article 7 yesahluko 2 ibala izinhlobo ezingama-59 zezibulala-zinambuzane zemvelaphi yezinambuzane evunyelwe ukusetshenziswa. I-Biopeanotides efana ne-Azadirachtin nama-pyrethrins afakiwe. Yize lezi zinto zikhishwe ezitshalweni zemvelo zichazwa ngokuthi "ubuthi obuphansi," ukufafaza ngokweqile kungahle kuholele ezinsalweni. Okukhathaza kakhulu ukuthi amazinga okuqinisekisa abeka isikhathi sokuhlanza inhlabathi ezinyangeni ezingama-36, kepha ama-metabolites we-glyphosate avela emijikelezweni yezolimo yangaphambilini asatholakala emanzini asemphethweni kwezinye izisekelo enyakatho ye-China Plain.
Amacala wechlorpyyrifosIzinsalela emibikweni yokuhlola zisebenza njengesixwayiso. Isisekelo esisodwa esiqinisekisiwe, esiseduze nendlwana yendabuko, yahlushwa ukungcoliswa kwe-Destoristide Drift ngesikhathi se-MonSon, okuholela ekutholeni okungu-0.02 mg / kg kwezinsalela ze-organophosphorus kumasampula esinanashi. Lokhu "ukungcoliswa kokuphambanisa" kudalula ukungafaneleki kohlelo lwesitifiketi olukhona ngokuqapha i-Farming Endaweni, ukudwengula ukuqhekeka ebumsulwa bezolimo eziphilayo.
II. Iqiniso lembuliwe ezindaweni zokucwaninga
Lapho usebenzisa igesi i-chromatography-mass spectrometry, ochwepheshe babeka umkhawulo wokutholwa kwamasampula ku-0.001 mg / kg level. Idatha ikhombisa ukuthi ama-90% amasampula amahle ayenamazinga asele asele 1/50 kuphela kuya ku-1/11 kuphela alabo emifino ejwayelekile, okulingana nokuphonsa amaconsi amabili echibini echibini elijwayelekile lokubhukuda. Kodwa-ke, intuthuko ebukhwini banamuhla bathole ukuthwebula ama-molecule ezingeni le-in-in-billion, okwenza i- "zero desidi demide" ingenakwenzeka.
Ubulukhuni be-Cross-Containt Chains ingaphezulu kwemicabango. Ukungcoliswa kweWarehouse ngenxa yezimoto ezihlanjululwe ngokuhlanzwa ama-akhawunti ama-42% wamanani ezigameko, ngenkathi ukuxhumana nokungcoliseka okubangelwa ukubekwa okuxubile kumashalofu angama-31. Ngokwezifiso ezinkulu, ama-antibiotic ahlanganiswe neminye yomanyolo we-organic worgesition agcina angena kumaseli emifino ngokusebenzisa i-bioaccum.
III. Indlela enengqondo yokuvuselela ukwethembana
Ukubhekana noMbiko Wokuhlola, umlimi we-organic waveza uhlelo lwabo "lokulandela umkhondo obonakalayo" Le ndlela yokubeka izinqubo zokukhiqiza ku-Open ukwakha kabusha ukuzethemba kwabathengi.
Ochwepheshe bokuphepha kokudla bancoma ukwamukela "indlela yokuhlanza kathathu": Ukufaka emanzini abhaka ama-soda ukubola ama-Pesticides amafutha, usebenzisa i-ultrasonic cleaner ukususa ama-adsorbetes angaphezulu kwe-100 ° C ukuze i-enzymes eyi-100. Lezi zindlela zingasusa ama-97,6% ezinsalela ze-TRACE, okwenza ubuhlakani bezokuvikela ezempilo buqine.
Idatha yokuhlola elenziwa elebhu akufanele isebenze njengesinqumo esaphika inani lezolimo eziphilayo. Lapho siqhathanisa i-0.008 mg / kg ye-Chlorpyrifos eyayinsalela nge-1.2 mg / kg etholakele e-celery evamile, sisakwazi ukubona ukusebenza okubalulekile kwezinhlelo zokukhiqiza ze-organic ekunciphiseni ukusetshenziswa kwezinambuzane. Mhlawumbe ubumsulwa beqiniso abuqambi amanga ku-zero ngokuphelele, kepha ngokuqhubekayo usondela ku-zero, okudinga abakhiqizi, abalawuli kanye nabathengi ukuthi bafake inethiwekhi yekhwalithi eqinile.
