I. "Agace k'imvi" k'ibipimo ngenga

Gufungura "Amategeko agenga ishyirwa mu bikorwa ry'icyemezo cy'ibicuruzwa kama," Ingingo ya 7 yo mu gice cya 2 yerekana neza ubwoko 59 bw’imiti yica udukoko twangiza ibihingwa n’amabuye y'agaciro yemerewe gukoreshwa. Imiti ya biopesticide nka azadirachtin na pyrethrine zirimo cyane. Nubwo ibyo bintu byakuwe mubihingwa bisanzwe bisobanurwa nk "uburozi buke," gutera cyane birashobora kuganisha ku bisigazwa. Ikibazo gihangayikishije cyane ni uko ibipimo byemeza ko hashyizweho igihe cy’amezi 36 yo kweza ubutaka, ariko metabolite ya glyphosate kuva mu bihe byashize by’ubuhinzi irashobora kugaragara mu mazi y’ubutaka ku birindiro bimwe na bimwe byo mu kibaya cy’Ubushinwa.

Imanza zachlorpyrifosibisigaye muri raporo y'ibizamini bikora nk'ikuburira. Ikibanza kimwe cyemewe, cyegeranye nubutaka gakondo, bwahuye n’umwanda w’udukoko twangiza udukoko mu gihe cy’imvura, bituma hamenyekana 0,02 mg / kg y’ibisigazwa bya organofosifore mu byitegererezo bya epinari. Iyi "umwanda utanduye" igaragaza uburyo sisitemu yo gutanga ibyemezo idahagije mugukurikirana byimazeyo ubuhinzi, bikuraho icyuho cy’ubuhinzi-mwimerere.

II. Ukuri Kumenyekana muri Laboratoire

Iyo ukoresheje gazi chromatografiya-rusange ya sprometrike, abatekinisiye bashiraho igipimo cyo gutahura ingero kurwego rwa 0.001 mg / kg. Amakuru yerekana ko 90% by'icyitegererezo cyiza cyari gifite ibisigisigi gusa 1/50 kugeza 1/100 muri ibyo mu mboga zisanzwe, bihwanye no guta ibitonyanga bibiri bya wino muri pisine isanzwe. Nyamara, iterambere mu buhanga bugezweho bwo gutahura ryatumye ifata molekile kurwego rwa miliyari imwe, bituma "ibisigisigi bya zeru" bidashoboka.

Ingorabahizi zinyuranyo zanduye zirenze ibitekerezo. Kwanduza ububiko kubera ibinyabiziga bitwara isuku bituzuye bingana na 42% byibyabaye, mugihe kwanduza kwanduzwa guterwa no kuvangavanga kububiko bwa supermarket bingana na 31%. Ubushishozi bwinshi, antibiyotike ivanze munganda zifumbire mvaruganda amaherezo yinjira mu ngirabuzimafatizo binyuze muri bioaccumulation.

III. Inzira Yumvikana yo Kwubaka Icyizere

Guhangana na raporo y'ibizamini, umuhinzi-mwimerere yerekanye "sisitemu yo gukurikiranwa mu mucyo": Kode ya QR kuri buri paki itanga uburenganzira bwo kubaza igipimo cy’imvange ya Bordeaux yakoreshejwe na raporo yo gupima ubutaka mu birometero bitatu. Ubu buryo bwo gushyira inzira yumusaruro kumugaragaro ni ukubaka icyizere cyabaguzi.

Inzobere mu bijyanye no kwihaza mu biribwa zirasaba ko hakoreshwa "uburyo bwo kweza butatu": gushira mu mazi ya soda kugira ngo ubore imiti yica udukoko twangiza ibinure, ukoresheje isuku ya ultrasonic kugirango ukureho adsorbates, hanyuma uhumeke amasegonda 5 kuri 100 ° C kugirango udakora imisemburo y’ibinyabuzima. Ubu buryo bushobora gukuraho 97,6% by'ibisigazwa by'ibisigisigi, bigatuma umurongo urinda ubuzima urushaho gukomera.

Ibizamini bya laboratoire ntibigomba kuba umwanzuro uhakana agaciro k'ubuhinzi-mwimerere. Iyo tugereranije 0.008 mg / kg by'ibisigisigi bya chlorpyrifos hamwe na 1,2 mg / kg byagaragaye muri seleri isanzwe, turashobora kubona akamaro gakomeye k'umusaruro ukomoka ku buhinzi mu kugabanya ikoreshwa ry'udukoko. Ahari isuku nyayo ntabwo iri muri zeru rwose, ariko mugukomeza kwegera zeru, bisaba abayikora, abagenzuzi, nabaguzi gufatanya kuboha urusobe rukomeye.
