Toxic Phthalates nyob rau hauv Sealants: Hidden Risks Thiab Lub Push Rau Cov Khoom Siv Hauv Tsev Zoo

Sealants muaj nyob thoob plaws hauv tsev, tsev kawm ntawv, thiab chaw ua haujlwm, tab sis lawv tsis tshua hla tib neeg lub siab. Txawm hais tias lawv muab sib xyaw rau hauv keeb kwm ntawm lub neej niaj hnub, cov khoom siv tsis zoo no tuaj yeem ua rau muaj kev cuam tshuam rau huab cua sab hauv tsev thiab tib neeg kev noj qab haus huv-.

Hauv kev tsim vaj tsev, sealants ua lub hom phiaj tseem ceeb: kev sib khi qhov khoob thiab tswj cov huab cua, ib qho haujlwm uas tau loj hlob tseem ceeb dua thaum muaj kev kub ntxhov ntawm huab cua tam sim no. Tu siab, txawm tias lawv siv dav, ntau cov sealants muaj cov tshuaj phem xws li isocyanates thiab phthalates. Cov khoom nruab nrab- cov tshuaj tsis haum no tuaj yeem tshem tawm- roj los ntawm cov sealants nyob rau lub sijhawm, ua rau huab cua sab hauv tsev thiab nkag mus rau hauv cov plua plav hauv tsev.

Phthalates paub tias cuam tshuam lub cev qhov sib npaug ntawm cov tshuaj hormonal thiab cuam tshuam nrog kev tsim muaj menyuam. Txawm hais tias qee qhov phthalates tau txwv tsis pub rau cov menyuam yaus cov khoom lag luam ntawm tsoomfwv qib siab thiab hauv xeev xws li Washington, California, thiab Vermont, cov pab pawg tsis muaj zog-xws li menyuam yaus thiab cov neeg cev xeeb tub- tseem raug cuam tshuam los ntawm ntau qhov chaw, suav nrog cov khoom siv hauv tsev xws li sealants.

Tam sim no, Washington Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv tau tshaj tawm txoj cai txwv tsis pub phthalates hauv vinyl flooring thiab tshuaj tsw qab hauv cov khoom tu tus kheej. Cov kev tshawb fawb tshawb fawb tau lees paub tias huab cua sab hauv tsev thiab cov plua plav hauv tsev yog txoj hauv kev tseem ceeb rau kev raug phthalate, ua rau cov kev cai no yog kauj ruam tseem ceeb rau kev txo qis.

Paub txog cov kev phom sij uas tshwm sim los ntawm phthalates thiab cov khoom siv hauv tsev ua si hauv kev nthuav tawm tib neeg rau cov co toxins, Toxic-Free Future koom tes nrog Healthy Building Network thiab Ecology Center of Michigan hauv 2021 thiab 2022 los kuaj phthalate ntawm sealants. Qhov kev pib no tsim los ntawm kev ua haujlwm yav dhau los nrog Ecology Center thiab lwm tus neeg koom tes txhawm rau tshem tawm phthalates los ntawm cov khw muag khoom yas hauv pem teb thiab txhawb nqa kev tswj xyuas tsis tu ncua hauv xeev Washington.

Rau txoj kev tshawb fawb tshiab no, pab pawg tau yuav thiab tshuaj xyuas 33 cov khoom siv sealant-xws li polyurethane, silicone, thiab acrylic latex ntau yam- feem ntau siv hauv kev tsim kho thiab kho dua tshiab, uas xav tias muaj phthalates. Cov neeg ua haujlwm ntawm Ecology Center tau siv Fourier-hloov infrared (FTIR) spectrometer los tshuaj xyuas phthalates, thiab kev kuaj kuaj ntxiv tau raug xa mus rau cov khoom uas kuaj pom qhov zoo.

Cov txiaj ntsig tau tshaj tawm tias rau ntawm 33 qhov kev sim cov sealants muaj cov phthalates siab heev- txog li 12% los ntawm qhov hnyav- suav nrog ob qho tib si diisononyl phthalate (DINP) thiab diisodecyl phthalate (DIDP). Tshwj xeeb tshaj yog, phthalates feem ntau pom nyob rau hauv "silane modified polymer" sealants: tsib ntawm xya lub sealants kuaj pom zoo. Qhov tseem ceeb, cov khoom 27 tseem tsis tau kuaj pom phthalates, qhia tau tias muaj kev nyab xeeb lwm txoj hauv kev.

Ntau lub tuam txhab sealant tau tso tseg tsis siv phthalates, thiab nws yog ib qho tseem ceeb uas tag nrho cov sealants raug tsim tsis muaj cov tshuaj phem no. Muaj kev nyab xeeb lwm txoj hauv kev rau phthalate- muaj cov sealants, xws li sodium silicate caulk thiab ua ntej- compressed polyurethane sib txuas.

Daim duab loj: Lub tsev noj qab haus huv nyob ntawm cov khoom noj qab haus huv

Toxic Building Materials Extend Beyond Sealants

Sealants tsuas yog ib qho piv txwv ntawm cov khoom siv hauv tsev uas muaj cov khoom xyaw lom, ua rau cov huab cua tsis zoo hauv tsev thiab muaj kev pheej hmoo rau kev noj qab haus huv. Los ntawm cov xim thiab hauv pem teb mus rau rwb thaiv tsev, ntau lwm yam khoom siv hauv tsev feem ntau suav nrog cov tshuaj uas tuaj yeem ua rau tib neeg noj qab haus huv -thiab nyob rau hauv txhua rooj plaub, muaj kev nyab xeeb dua lwm txoj kev.
