Cov kev txwv tsis ntev los no hauv Tebchaws Europe yog cov pov thawj ntawm kev txhawj xeeb ntxiv txog kev siv tshuaj tua kab thiab txo qis cov muv. Lub Chaw Tiv Thaiv Ib puag ncig tau txheeb xyuas ntau dua 70 cov tshuaj tua kab uas muaj tshuaj lom rau muv. Ntawm no yog cov pawg tseem ceeb ntawm cov tshuaj tua kab txuas rau muv tuag thiab pollinator poob.
Neonicotinoids Neonicotinoids (neonics) yog ib chav kawm ntawm cov tshuaj tua kab uas nws cov txheej txheem ntawm kev ua haujlwm tawm tsam lub hauv paus paj hlwb ntawm kab, ua rau tuag tes tuag taw thiab tuag. Kev tshawb fawb tau pom tias neonicotinoid residues tuaj yeem sau rau hauv paj ntoos thiab nectar ntawm cov nroj tsuag kho, ua rau muaj kev pheej hmoo rau pollinators. Vim qhov no thiab lawv txoj kev siv dav dav, muaj kev txhawj xeeb loj uas neonicotinoids ua lub luag haujlwm tseem ceeb hauv pollinator poob.
Neonicotinoid insecticides kuj tseem nyob hauv ib puag ncig thiab, thaum siv los kho cov noob, raug xa mus rau paj ntoos thiab nectar residues ntawm cov nroj tsuag kho. Ib noob yog txaus tua ib tug noog. Cov tshuaj tua kab no tuaj yeem ua paug rau hauv dej thiab ua rau muaj kuab lom heev rau cov dej hauv dej. Cov ntaub ntawv ntawm cov tshuaj tua kab neonicotinoid qhia txog ob qhov teeb meem tseem ceeb nrog cov txheej txheem sau npe tshuaj tua kab tam sim no thiab cov kev ntsuas kev pheej hmoo: kev vam khom rau kev lag luam-nyiaj pab kev tshawb fawb uas tsis sib haum nrog kev tshawb fawb ntawm cov phooj ywg, thiab qhov tsis txaus ntawm cov txheej txheem kev soj ntsuam kev pheej hmoo tam sim no los suav rau cov teebmeem sublethal ntawm tshuaj tua kab.
Sulfoxaflor tau sau npe thawj zaug hauv xyoo 2013 thiab tau tsim ntau qhov kev tsis sib haum xeeb. Suloxaflor yog ib hom tshuaj tua kab tshiab sulfenimide nrog cov yam ntxwv zoo ib yam li cov tshuaj tua kab neonicotinoid. Tom qab lub tsev hais plaub txiav txim siab, US Environmental Protection Agency (EPA) tau sau npe sulfenamide hauv xyoo 2016, txwv tsis pub siv los txo cov muv. Tab sis txawm hais tias qhov no txo qhov chaw ntawm kev siv thiab txwv lub sij hawm ntawm kev siv, lub cev toxicity ntawm sulfoxaflor xyuas kom meej tias cov kev ntsuas no yuav tsis txaus tshem tawm kev siv cov tshuaj no. Pyrethroids kuj tau pom tias ua rau tsis zoo rau kev kawm thiab kev coj tus cwj pwm ntawm muv. Pyrethroids feem ntau cuam tshuam nrog cov muv tuag thiab tau pom tias txo cov muv fertility, txo tus nqi ntawm cov muv loj hlob mus rau cov neeg laus, thiab ncua lawv lub sij hawm ntawm immaturity. Pyrethroids yog dav pom nyob rau hauv paj ntoos. Feem ntau siv pyrethroids muaj xws li bifenthrin, deltamethrin, cypermethrin, phenethrin, thiab permethrin. Dav siv rau kev tswj kab tsuag sab hauv tsev thiab nyom, Fipronil yog cov tshuaj tua kab uas muaj tshuaj lom rau cov kab. Nws yog tshuaj lom me me thiab tau cuam tshuam nrog kev cuam tshuam hormonal, thyroid cancer, neurotoxicity, thiab kev ua me nyuam. Fipronil tau pom tias txo tus cwj pwm ua haujlwm thiab kev kawm muaj peev xwm hauv muv. Organophosphates. Organophosphates xws li malathion thiab spikenard yog siv rau hauv kev tswj yoov tshaj cum thiab tuaj yeem ua rau muv muaj kev pheej hmoo. Ob leeg muaj tshuaj lom heev rau muv thiab lwm yam kab mob uas tsis yog lub hom phiaj, thiab cov muv tuag tau raug tshaj tawm nrog cov tshuaj toxicity tsawg. Cov muv raug cuam tshuam ncaj qha rau cov tshuaj tua kab los ntawm cov khoom seem ntawm cov nroj tsuag thiab lwm qhov chaw tom qab yoov tshaj cum. Pollen, wax thiab zib mu tau pom tias muaj cov seem.
