New Southern Cross University kev tshawb fawb txog tshuaj tua kab tawm qhia tias siv tshuaj tua kab ntau tuaj yeem cuam tshuam rau cw thiab oysters.
Cov kws tshawb fawb ntawm National Marine Science Center hauv Coffs Harbor nyob rau sab qaum teb ntug dej hiav txwv ntawm New South Wales tau tshawb pom tias imidacloprid (pom zoo siv los ua tshuaj tua kab, fungicide thiab tshuaj tua kab mob hauv Australia) tuaj yeem cuam tshuam rau kev noj cw.
Tus thawj coj hauv chaw Kirsten Benkendorff (Kirsten Benkendorff) tau hais tias rau hom nqaij nruab deg, lawv muaj kev txhawj xeeb tshwj xeeb txog cov tshuaj tua kab dej-soluble cuam tshuam rau cw.
Nws hais tias: “Lawv muaj feem cuam tshuam nrog cov kab, yog li peb tau ua qhov kev xav tias lawv yuav nkag siab zoo rau cov tshuaj tua kab.Qhov no yeej yog qhov peb pom. "
Ib txoj kev tshawb fawb hauv chaw soj nstuam pom tau hais tias kev kis cov tshuaj tua kab los ntawm cov dej tsis huv los yog pub mis yuav ua rau muaj kev noj zaub mov tsis zoo thiab txo cov nqaij zoo ntawm cov tsov dub.
Xib fwb Benkendorf tau hais tias: "Qhov ib puag ncig peb tau kuaj pom yog siab li 250 micrograms ib liter, thiab qhov cuam tshuam sublethal ntawm cw thiab oysters yog li 1 txog 5 micrograms ib liter."
"Nqe tiag tiag pib tuag ntawm ib puag ncig concentration ntawm 400 micrograms ib liter.
"Qhov no yog qhov peb hu ua LC50, uas yog koob tshuaj tuag ntawm 50. Koj xav kom 50% ntawm cov neeg tuag nyob ntawd."
Tab sis cov kws tshawb fawb kuj pom nyob rau hauv lwm txoj kev tshawb fawb uas raug rau neonicotine kuj tseem ua rau lub cev tsis muaj zog ntawm Sydney oysters.
Xib fwb Benkendorf tau hais tias: "Yog li ntawd, ntawm qhov tsis tshua muaj siab, qhov cuam tshuam rau cw yog qhov hnyav heev, thiab cov oysters tiv taus ntau dua cov cw."
"Tab sis peb yuav tsum tau pom qhov cuam tshuam rau lawv lub cev tiv thaiv kab mob, uas txhais tau hais tias lawv muaj feem yuav raug kab mob."
Xib fwb Benkendorf tau hais tias: "Los ntawm qhov kev xav tias lawv nqus tau lawv los ntawm ib puag ncig, qhov no yog qhov tsim nyog yuav tsum tau saib xyuas."
Nws tau hais tias txawm hais tias xav tau kev tshawb fawb ntxiv, nws tau pom tias nws yuav tsum tau tswj hwm kev siv tshuaj tua kab thiab dej ntws hauv cov ntug dej hiav txwv.
Tricia Beatty, tus thawj coj ntawm New South Wales Professional Fishermen Association, tau hais tias txoj kev tshawb no ua rau muaj kev phom sij thiab tsoomfwv New South Wales yuav tsum tau nqis tes ua tam sim.
Nws tau hais tias: "Tau ntau xyoo, peb txoj kev lag luam tau hais tias peb txhawj xeeb txog kev cuam tshuam tshuaj lom neeg ntawm kev lag luam nce toj."
"Peb txoj kev lag luam muaj nqis txog $ 500 lab rau New South Wales kev lag luam, tab sis tsis tas li ntawd xwb, peb kuj tseem yog cov pob txha ntawm ntau lub zej zog ntug hiav txwv.
"Australia yuav tsum ua tib zoo kawm txog kev txwv tsis pub muaj tshuaj nyob hauv Europe thiab luam tawm ntawm no."
Ms. Beatty tau hais tias: “Tsis yog rau lwm cov crustaceans thiab molluscs, tab sis kuj nyob rau tag nrho cov saw zaub mov;ntau hom nyob rau hauv peb estuary noj cov cw. "
Neonicotinoid tshuaj tua kab-uas tau raug txwv hauv Fabkis thiab EU txij li xyoo 2018-tau raug tshuaj xyuas los ntawm Australian Pesticide and Veterinary Drug Administration (APVMA).
APVMA tau hais tias nws tau pib qhov kev tshuaj xyuas hauv 2019 tom qab "kev soj ntsuam cov ntaub ntawv tshawb fawb tshiab txog kev pheej hmoo ib puag ncig thiab ua kom ntseeg tau tias cov khoom lag luam muaj kev nyab xeeb raws li cov qauv niaj hnub no."
Qhov kev txiav txim siab ntawm kev tswj hwm yuav tsum tau tshaj tawm thaum lub Plaub Hlis 2021, thiab tom qab ntawd tom qab peb lub hlis ntawm kev sib tham ua ntej kev txiav txim siab zaum kawg ntawm cov tshuaj.
Txawm hais tias cov kws tshawb fawb tau taw qhia tias cov neeg cog qoob loo yog ib qho ntawm cov neeg siv tseem ceeb ntawm imidacloprid ntawm ntug dej hiav txwv ntawm Coffs, lub ncov ntawm kev lag luam tau tiv thaiv nws txoj kev siv cov tshuaj no.
Rachel Mackenzie, tus thawj coj ntawm Australian Berry Company, tau hais tias kev siv cov tshuaj no yuav tsum raug lees paub.
Nws hais tias: "Nws nyob hauv Baygon, thiab tib neeg tuaj yeem tswj hwm lawv cov dev nrog hma.Nws yog dav siv rau kev tsim kho tshiab termite tswj;qhov no tsis yog qhov teeb meem loj. "
“Qhov thib ob, kev tshawb fawb tau ua nyob rau hauv lub chaw kuaj mob raws li kev kuaj mob.Obviously, lawv yog preliminary heev.
"Cia peb nyob deb ntawm qhov tseeb ntawm qhov kev lag luam berry no thiab xav txog qhov tseeb tias cov khoom no muaj ntau dua 300 siv rau npe hauv Australia."
Ms. Mackenzie tau hais tias kev lag luam yuav 100% ua raws li APVMA qhov kev tshuaj xyuas cov lus xaus ntawm neonicotinoids.
Cov kev pabcuam yuav muaj cov ntaub ntawv muab los ntawm Fab Kis Fab Kis Fab Kis Fab Kis Fab Kis (AFP), APTN, Reuters, AAP, CNN thiab BBC World Service.Cov ntaub ntawv no muaj cai luam tawm thiab tsis tuaj yeem luam tawm.
