I. "Nzvimbo yeGrey" yeOrganic Standards

Kutanga "Mitemo yeKushandiswa kweChitupa Chezvigadzirwa Zvechisikigo," Chikamu 7 cheChitsauko 2 chinotsanangura zvakajeka mhando makumi mashanu nemapfumbamwe dzemishonga inouraya zvipembenene inobva mumiti uye muzvicherwa inotenderwa kushandiswa. Mishonga inouraya zvipembenene yakaita seazadirachtin nepyrethrins inosanganisirwa zvakanyanya. Kunyangwe zvinhu izvi zvakatorwa kubva mumiti yechisikigo zvichitsanangurwa se "chepfu shoma," kupfapfaidza zvakanyanya kunogona kutungamira kune zvasara. Chinonyanya kunetsa ndechekuti mwero wezvitupa unoisa nguva yekuchenesa ivhu kwemwedzi makumi matatu nematanhatu, asi glyphosate metabolites kubva mukurima kwekare inogona kuonekwa mumvura yepasi pevhu pane dzimwe nzvimbo muNorth China Plain.

Nyaya dzechlorpyrifosZvisaririra zviri mumishumo yekuyedza zvinoshanda senyevero. Imwe nzvimbo yakasimbiswa, iri pedyo nenzvimbo dzekurima dzechinyakare, yakatambura nekusvibiswa kwezvipembenene zvinouraya zvipembenene munguva yemwaka wemvura, zvichiita kuti pawanikwe 0.02 mg/kg yezvinosara zve organophosphorus mumienzaniso yespinachi. "Kusvibiswa uku kusingashande" kunoburitsa pachena kusakwana kwehurongwa huripo hwezvitupa mukutarisa nharaunda yekurima nenzira inochinja-chinja, zvichibvisa mukaha mukuchena kwekurima kweorganic.

II. Chokwadi Chinoburitswa Mumarabhoritari

Pakushandisa gas chromatography-mass spectrometry, mainjiniya vanoisa muganho wekuona masampuli pachiyero che 0.001 mg/kg. Data rinoratidza kuti 90% yemasampuli akanaka aive nemazinga e residue ari pakati pe 1/50 kusvika 1/100 chete eari mumiriwo yemazuva ano, zvakaenzana nekudonhedza madonhwe maviri einki mudziva rekushambira. Zvisinei, kufambira mberi muhunyanzvi hwemazuva ano hwekuona mamorekuru kwakabvumira kubata mamorekuru pachiyero che 1-in-a-bhiriyoni, zvichiita kuti "zero residue" ive basa risingabviri.

Kuomarara kwecheni dzinosvibisa zvinhu zvakasiyana-siyana hakufungidzirwi. Kusvibiswa kwemudura wezvinhu nekuda kwemotokari dzisina kucheneswa zvakakwana kunoita kuti pave ne42% yezviitiko, nepo kusvibiswa kwezvinowanikwa muzvitoro kunokonzerwa nekusanganiswa kwenzvimbo mumasherufu ezvitoro kunoita 31%. Chinonyanya kushamisa ndechekuti mishonga inorwisa mabhakitiriya inosanganiswa mune zvimwe zvinhu zvinogadzirwa nefetereza yeorganic inozopedzisira yapinda mumasero emuriwo kuburikidza nekuunganidzwa kwezviwanikwa.

III. Nzira Ine Mufungo Yekuvakazve Kuvimbana

Vachitarisana nemushumo wekuyedza, murimi wezvirimwa zvechisikigo akaratidza "system yavo yekutevedza nzira yakajeka": QR code papakeji yega yega inobvumira kubvunza chiyero chemusanganiswa weBordeaux wakashandiswa uye mishumo yekuyedza ivhu yemakiromita matatu akapoteredza. Iyi nzira yekuisa maitiro ekugadzira pachena iri kuvakazve chivimbo chevatengi.

Nyanzvi dzekuchengetedza chikafu dzinokurudzira kushandisa "nzira yekuchenesa katatu": kunyikwa mumvura yebaking soda kuti iore mishonga inonyunguduka mumafuta, kushandisa ultrasonic cleaner kubvisa adsorbates pamusoro, uye kuibvisa kwemasekonzi mashanu pa100°C kuti imise ma enzymes ehupenyu. Nzira idzi dzinogona kubvisa 97.6% yezvasara zvezvimedu, zvichiita kuti dziviriro yehutano ive yakasimba.

Ruzivo rwekuyedzwa kwemurabhoritari harufanirwe kushanda semutongo unoramba kukosha kwekurima kweorganic. Kana tikaenzanisa 0.008 mg/kg ye chlorpyrifos residue ne 1.2 mg/kg yakawanikwa mu celery yakajairika, tinogona kuona kushanda kwakakosha kwemaitiro ekugadzira organic mukuderedza kushandiswa kwemishonga inouraya zvipembenene. Pamwe kuchena kwechokwadi hakusi pazero chaiyo, asi pakuramba kuri pazero, izvo zvinoda kuti vagadziri, vatongi, nevatengi vabatane kugadzira network yemhando yepamusoro.
