(Tshwj tsis yog tshuaj tua kab, Lub Xya Hli 8, 2024) Thov xa cov lus ua ntej hnub Wednesday, Lub Xya Hli 31, 2024. Acephate yog cov tshuaj tua kab uas muaj nyob hauv tsev neeg muaj tshuaj lom organophosphate (OP) thiab muaj tshuaj lom heev uas Lub Chaw Tiv Thaiv Ib puag ncig tau tawm tswv yim txwv tsis pub nws tsuas yog systemic tswj rau ntoo.Lub sijhawm hais lus tau qhib tam sim no, thiab EPA yuav lees txais cov lus hais txog hnub Wednesday, Lub Xya Hli 31, tom qab ncua sijhawm lub Xya Hli kawg.Nyob rau hauv cov ntaub ntawv siv ntxiv no, EPA tseem tsis paub tias cov kab mob neonicotinoidtshuaj tua kabtuaj yeem ua rau muaj kev puas tsuaj loj rau cov ecosystems los ntawm cov kab mob lom uas tsis txaus ntseeg.
>> Tshaj tawm cov lus hais txog acephate thiab qhia rau EPA tias cov tshuaj tua kab yuav tsum tsis txhob siv yog tias cov qoob loo tuaj yeem tsim cov organically.
EPA tab tom thov kom txiav tawm tag nrho cov kev siv acephate, tshwj tsis yog kev txhaj tshuaj ntoo, txhawm rau tshem tawm txhua qhov kev pheej hmoo uas nws tau txheeb xyuas tias tshaj nws qib kev txhawj xeeb rau cov zaub mov / dej haus, kev phom sij hauv tsev thiab kev ua haujlwm, thiab tsis yog lub hom phiaj kev phom sij lom neeg.txaus ntshai.Tshaj li tshuaj tua kab tau sau tseg tias thaum txoj kev txhaj tshuaj tsob ntoo tsis ua rau muaj kev noj zaub mov ntau dhau lossis muaj kev phom sij rau kev noj qab haus huv, thiab tsis ua rau muaj kev phom sij rau kev ua haujlwm lossis tib neeg kev noj qab haus huv tom qab siv, lub koom haum tsis quav ntsej txog kev pheej hmoo ntawm ib puag ncig.Lub chaw haujlwm tsis ntsuas qhov kev pheej hmoo ntawm ib puag ncig ntawm kev siv cov ntoo txhaj tshuaj, tab sis hloov kev xav tias qhov kev siv no tsis ua rau muaj kev pheej hmoo loj rau cov kab mob uas tsis yog hom phiaj.Hauv qhov sib piv, kev siv cov ntoo txhaj tshuaj ua rau muaj kev pheej hmoo loj rau cov pollinators thiab qee hom noog uas tsis tuaj yeem txo tau thiab yog li yuav tsum tau muab tso rau hauv acephate tshem tawm.
Thaum txhaj rau hauv tsob ntoo, cov tshuaj tua kab yog txhaj ncaj qha rau hauv lub cev, sai sai absorbed thiab faib thoob plaws hauv cov hlab ntsha.Vim tias acephate thiab nws cov khoom tawg methamidophos yog cov tshuaj tua kab uas muaj kuab heev, cov tshuaj no raug xa mus rau txhua qhov chaw ntawm tsob ntoo, suav nrog paj ntoos, kua txiv, resin, nplooj thiab ntau dua.Bees thiab qee cov noog xws li hummingbirds, woodpeckers, sapsuckers, vines, nuthatches, chickadees, thiab lwm yam tuaj yeem raug cov khib nyiab los ntawm cov ntoo uas tau txhaj tshuaj acephate.Bees raug nthuav tawm tsis tau tsuas yog thaum khaws cov paj ntoos tsis huv, tab sis kuj thaum sau cov kua txiv thiab cov resin siv los tsim lub Hive's tseem ceeb propolis.Ib yam li ntawd, cov noog tuaj yeem raug cov tshuaj lom acephate / metamidophos residues thaum lawv noj cov kab mob kab mob, kab tsuag ntoo / larvae, thiab nplooj-munching kab / larvae.
Txawm hais tias cov ntaub ntawv raug txwv, US Environmental Protection Agency tau txiav txim siab tias kev siv acephate tuaj yeem ua rau muaj kev pheej hmoo rau muv.Txawm li cas los xij, tag nrho cov kev tshawb fawb pollinator ntawm acephate los yog methamidophos tsis tau tshaj tawm, yog li tsis muaj cov ntaub ntawv hais txog mob qhov ncauj, tus neeg laus mob ntev, los yog cov kab mob larval toxicity rau zib mu muv;Cov ntaub ntawv sib txawv no nthuav tawm qhov tsis paub tseeb hauv kev ntsuam xyuas qhov cuam tshuam ntawm acephate ntawm pollinators, vim tias qhov kev raug mob yuav txawv ntawm lub neej theem thiab lub sij hawm ntawm kev raug (cov neeg laus piv rau larvae thiab mob ntev heev, feem).Cov xwm txheej tsis zoo nrog qhov tshwm sim thiab qhov tshwm sim tshwm sim, suav nrog kev tuag ntawm muv, tau cuam tshuam nrog muv raug acephate thiab / lossis methamidophos.Nws yog qhov tsim nyog xav tias kev txhaj tshuaj acephate rau hauv tsob ntoo tsis txo qhov kev pheej hmoo ntawm muv piv rau cov kev kho mob foliar, tab sis yuav ua rau muaj kev cuam tshuam ntau dua rau cov tshuaj txhaj rau hauv tsob ntoo, yog li ua rau muaj kev pheej hmoo ntawm toxicity.Lub koom haum tau muab cov lus qhia txog kev phom sij rau tsob ntoo uas tau hais tias, "Cov khoom no muaj tshuaj lom rau cov muv.Daim ntawv lo lo lus no tsis txaus los tiv thaiv muv thiab lwm yam kab mob los yog qhia qhov kev pheej hmoo loj heev. "
Cov kev pheej hmoo ntawm kev siv cov tshuaj acetate thiab tsob ntoo txhaj tshuaj tsis tau raug soj ntsuam tag nrho rau cov kab mob uas muaj kev puas tsuaj.Ua ntej ua tiav nws qhov kev tshuaj xyuas ntawm acephate cov ntawv sau npe, EPA yuav tsum ua kom tiav ib qho kev ntsuam xyuas ntawm cov npe tsiaj thiab txhua qhov kev sib tham tsim nyog nrog US Fish thiab Wildlife Service thiab National Marine Fisheries Service, nrog rau kev saib xyuas tshwj xeeb rau cov npe noog thiab kab thiab cov hom noog thiab kab no. .siv cov ntoo txhaj rau foraging, foraging thiab zes lub hom phiaj.
Hauv xyoo 2015, lub koom haum ua tiav kev tshuaj xyuas tag nrho ntawm endocrine disruptor acephates thiab xaus lus tias tsis muaj cov ntaub ntawv ntxiv uas yuav tsum tau ntsuas qhov muaj feem cuam tshuam rau cov tshuaj estrogen, androgen, lossis thyroid pathways hauv tib neeg lossis tsiaj qus.Txawm li cas los xij, cov ntaub ntawv tsis ntev los no qhia tias endocrine cuam tshuam cov peev xwm ntawm acephate thiab nws qhov kev puas tsuaj ntawm methamidophos los ntawm txoj hauv kev uas tsis yog receptor-mediated tej zaum yuav muaj kev txhawj xeeb, thiab yog li EPA yuav tsum hloov kho nws qhov kev ntsuam xyuas ntawm endocrine cuam tshuam kev pheej hmoo ntawm acephate.
Tsis tas li ntawd, nyob rau hauv nws qhov kev ntsuam xyuas ntawm kev ua tau zoo, Lub Chaw Saib Xyuas Kev Tiv Thaiv Ib Cheeb Tsam tau xaus lus tias qhov txiaj ntsig ntawm kev txhaj tshuaj acetate hauv kev tswj cov kab tsuag feem ntau me me vim tias ob peb txoj hauv kev muaj txiaj ntsig zoo rau cov kab tsuag feem ntau.Yog li, qhov kev pheej hmoo siab rau cov muv thiab cov noog uas cuam tshuam nrog kev kho cov ntoo nrog acephate tsis yog qhov tsim nyog los ntawm qhov kev pheej hmoo-cov txiaj ntsig zoo.
> Tshaj tawm cov lus qhia txog acephate thiab qhia rau EPA tias yog cov qoob loo tuaj yeem cog qoob loo, yuav tsum tsis txhob siv tshuaj tua kab.
Txawm hais tias qhov tseem ceeb tshaj plaws ntawm kev tshuaj xyuas cov tshuaj tua kab organophosphate, EPA tau ua tsis tiav los tiv thaiv cov neeg muaj kev phom sij tshaj plaws rau lawv cov teebmeem neurotoxic - cov neeg ua liaj ua teb thiab cov menyuam yaus.Xyoo 2021, Earthjustice thiab lwm lub koom haum tau hais kom Lub Chaw Saib Xyuas Kev Tiv Thaiv Ib puag ncig kom tshem tawm cov tshuaj tua kab mob neurotoxic heev.Lub caij nplooj ntoo hlav no, Consumer Reports (CR) tau ua txoj kev tshawb fawb tshaj plaws ntawm cov tshuaj tua kab hauv cov khoom, pom tias raug rau ob pawg tshuaj loj - organophosphates thiab carbamates - yog qhov txaus ntshai tshaj plaws, thiab tseem cuam tshuam nrog kev pheej hmoo ntawm mob qog noj ntshav, ntshav qab zib thiab. mob plawv.kab mob.Raws li qhov kev tshawb pom no, CR tau hais kom Lub Chaw Tiv Thaiv Ib puag ncig "txhaum siv cov tshuaj tua kab no rau txiv hmab txiv ntoo thiab zaub."
Ntxiv rau cov teeb meem saum toj no, EPA tsis tau hais txog kev cuam tshuam ntawm endocrine.EPA kuj tseem tsis xav txog cov neeg tsis muaj zog, raug kev sib xyaw ua ke, thiab kev sib koom ua ke thaum teeb tsa cov zaub mov seem uas tau txais.Tsis tas li ntawd, cov tshuaj tua kab ua rau peb cov dej thiab huab cua, ua rau muaj kev puas tsuaj rau biodiversity, ua phem rau cov neeg ua liaj ua teb, thiab tua muv, noog, ntses, thiab lwm yam tsiaj qus.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias USDA-certified organic zaub mov tsis siv tshuaj tua kab mob lom hauv nws cov khoom.Cov tshuaj tua kab residues pom nyob rau hauv cov khoom organic, nrog rau qee qhov kev zam, yog qhov tshwm sim ntawm cov tshuaj lom neeg ua liaj ua teb uas tsis muaj tshuaj lom vim muaj tshuaj tua kab, dej paug, lossis cov av seem hauv qab.Tsis tsuas yog cov khoom noj organic zoo dua rau tib neeg kev noj qab haus huv thiab ib puag ncig ntau dua li kev tsim tshuaj lom neeg, qhov tseeb kev tshawb fawb tseem qhia txog cov organic proponents tau ntev hais tias: cov zaub mov organic zoo dua, ntxiv rau qhov tsis muaj tshuaj lom los ntawm cov zaub mov zoo. cov khoom.Nws yog cov khoom noj muaj txiaj ntsig thiab tsis muaj tshuaj lom neeg lossis ua paug rau cov zej zog uas cog zaub mov.“
Kev tshawb fawb luam tawm los ntawm Lub Chaw Organic qhia tau hais tias cov zaub mov organic tau qhab nia siab dua hauv qee qhov chaw tseem ceeb, xws li tag nrho cov peev xwm antioxidant, tag nrho cov polyphenols, thiab ob qho tseem ceeb flavonoids, quercetin thiab kaempferol, tag nrho cov uas muaj kev noj haus.Phau ntawv Journal of Agricultural Food Chemistry tshwj xeeb tshuaj xyuas tag nrho cov ntsiab lus phenolic ntawm blueberries, strawberries, thiab pob kws thiab pom tias cov zaub mov cog qoob loo muaj cov ntsiab lus phenolic ntau dua.Phenolic tebchaw yog ib qho tseem ceeb rau cov nroj tsuag kev noj qab haus huv (tiv thaiv kab thiab kab mob) thiab tib neeg noj qab haus huv vim hais tias lawv muaj "muaj zog antioxidant kev ua si thiab ntau yam pharmacological zog, xws li anticancer, antioxidant, thiab platelet aggregation inhibitory kev ua si."
Muab cov txiaj ntsig ntawm kev tsim cov organic, EPA yuav tsum siv cov organic ntau lawm raws li qhov ntsuas thaum ntsuas qhov txaus ntshai thiab cov txiaj ntsig ntawm cov tshuaj tua kab.Yog tias cov qoob loo tuaj yeem cog qoob loo organically, yuav tsum tsis txhob siv tshuaj tua kab.“
