Kafukufuku wa New Southern Cross University pakuyenda kwa mankhwala ophera tizilombo akuwonetsa kuti mankhwala omwe amagwiritsidwa ntchito kwambiri amatha kukhudza shrimp ndi oyster.
Asayansi a ku National Marine Science Center ku Coffs Harbor ku North Coast ku New South Wales apeza kuti imidacloprid (yovomerezeka kuti igwiritsidwe ntchito ngati mankhwala ophera tizilombo, fungicide ndi parasiticide ku Australia) ingakhudze khalidwe la kudyetsa shrimp.
Woyang'anira malo a Kirsten Benkendorff (Kirsten Benkendorff) adati kwa mitundu ya nsomba zam'madzi, amakhudzidwa kwambiri ndi momwe mankhwala osungunuka m'madzi amakhudzira shrimp.
Iye anati: “Zimagwirizana kwambiri ndi tizilombo, choncho tinaganiza kuti mwina amakhudzidwa kwambiri ndi mankhwala ophera tizilombo.Izi ndi zomwe tapeza. ”
Kafukufuku wopangidwa mu labotale adawonetsa kuti kukhudzana ndi mankhwala ophera tizilombo kudzera m'madzi oipitsidwa kapena chakudya kungayambitse kuperewera kwa zakudya komanso kuchepa kwa nyama ya nkhanu zakuda.
Pulofesa Benkendorf anati: “Chilengedwe chimene tapeza n’chakuti 250 micrograms pa lita imodzi, ndipo mphamvu yoopsa ya shrimp ndi oyster ndi pafupifupi 1 mpaka 5 micrograms pa lita imodzi.”
"Nkhumba zinayamba kufa pamalo ozungulira pafupifupi ma micrograms 400 pa lita imodzi.
"Iyi ndi yomwe timatcha LC50, yomwe ndi mlingo wakupha wa 50. Mukufuna kuti 50% ya anthu afere kumeneko."
Koma ofufuzawo adapezanso mu kafukufuku wina kuti kukhudzana ndi neonicotine kungathenso kufooketsa chitetezo cha mthupi cha oyster aku Sydney.
Pulofesa Benkendorf adati: "Chifukwa chake, pazambiri zotsika kwambiri, chiwopsezo cha shrimp chimakhala chowopsa, ndipo oyster amakhala osamva kuposa shrimp."
"Koma tikuyenera kuti tawona momwe chitetezo chawo cha mthupi chimakhudzira, zomwe zikutanthauza kuti akhoza kutenga matenda."
Pulofesa Benkendorf anati: “Poona kuti amawatenga m’chilengedwe, zimenezi n’zofunikadi kuziganizira.”
Ananenanso kuti ngakhale kafukufuku wowonjezera akufunika, apeza kuti ndikofunikira kuyang'anira bwino kugwiritsa ntchito mankhwala ophera tizilombo komanso kusefukira m'mphepete mwa nyanja.
Tricia Beatty, wamkulu wa bungwe la New South Wales Professional Fishermen Association, adati kafukufukuyu adayambitsa ngozi ndipo boma la New South Wales liyenera kuchitapo kanthu mwachangu.
Iye anati: “Kwa zaka zambiri, makampani athu akhala akunena kuti tikuda nkhawa kwambiri ndi mmene mankhwalawo amakhudzidwira kumtunda kwa mafakitale.”
"Makampani athu ndi ofunika $ 500 miliyoni ku chuma cha New South Wales, koma osati zokhazo, ndifenso msana wa madera ambiri am'mphepete mwa nyanja.
"Australia ikuyenera kuphunzira mosamala za kuletsa kwa mankhwala ku Europe ndikutengera apa."
Mayi Beatty anati: “Osati kokha pa nkhanu ndi ma mollusk ena, komanso pa ndandanda yonse ya chakudya;mitundu yambiri m’mphepete mwa nyanja yathu imadya nsombazi.”
Mankhwala ophera tizilombo a Neonicotinoid-omwe adaletsedwa ku France ndi EU kuyambira 2018-awunikiridwa ndi Australian Pesticide and Veterinary Drug Administration (APVMA).
APVMA idati idayamba kuwunikanso mu 2019 "atawunika zatsopano zasayansi zokhudzana ndi kuopsa kwa chilengedwe ndikuwonetsetsa kuti zonena zachitetezo chazinthu zikukwaniritsa zomwe zikuchitika masiku ano."
Lingaliro la kasamalidwe koyenera likuyembekezeka kuperekedwa mu Epulo 2021, kenako pakatha miyezi itatu ya zokambirana zisanachitike chigamulo chomaliza cha mankhwalawo.
Ngakhale ochita kafukufuku amanena kuti olima mabulosi ndi mmodzi mwa omwe amagwiritsa ntchito imidacloprid pamphepete mwa nyanja ya Coffs, nsonga yamakampaniyi yateteza kugwiritsa ntchito mankhwalawa.
Rachel Mackenzie, mkulu wa kampani ya Australian Berry Company, anati kufala kwa mankhwalawa kuyenera kuzindikirika.
Iye anati: “Ili ku Baygon, ndipo anthu amatha kuletsa agalu awo ndi utitiri.Amagwiritsidwa ntchito kwambiri poletsa chiswe chatsopano;ili si vuto lalikulu.”
"Chachiwiri, kafukufukuyu adachitika mu labotale pansi pazikhalidwe za labotale.Mwachiwonekere, iwo ndi oyambirira kwambiri.
"Tiyeni tipewe kukhudzidwa ndi bizinesi ya mabulosiyi ndipo tiganizire kuti mankhwalawa ali ndi ntchito zoposa 300 zomwe zidalembetsedwa ku Australia."
Mayi Mackenzie adanena kuti makampaniwa adzatsatira 100% malingaliro a APVMA pa neonicotinoids.
