Txawm li cas los xij, yog tias nws nkag mus rau hauv lub ntsws, nws tuaj yeem ua rau mob ntsws xws li mob ntsws; irreversible, mus tas li lub ntsws puas; thiab txawm tuag. Ib txhia hydrocarbons tuaj yeem ua rau lwm yam teebmeem, suav nrog coma, qaug dab peg, lub plawv tsis sib xws lossis kev puas tsuaj rau lub raum lossis daim siab.
Tsis tas li ntawd, puas yog hydrocarbons lom?
Ingestion ntawm hydrocarbons , xws li roj av distillates (piv txwv li, roj av, kerosene, roj ntxhia, roj teeb, xim thinners), ua rau muaj kev cuam tshuam tsawg kawg nkaus tab sis tuaj yeem ua rau mob ntsws loj heev. Tshuaj lom muaj peev xwm tsuas yog nyob ntawm viscosity, ntsuas hauv Saybolt vib nas this universal (SSU).
Tsis tas li ntawd, hydrocarbons cuam tshuam rau tib neeg lub cev li cas? nqos hydrocarbons ua rau hnoos thiab txham, uas tso cai rau cov hydrocarbon kua nkag mus rau hauv cov hlab ntsws thiab ua rau lub ntsws ua rau mob hnyav, mob hnyav hauv nws tus kheej (tshuaj mob ntsws), thiab tuaj yeem ua rau mob ntsws loj.
Ib yam li ntawd, nws raug nug, puas yog hydrocarbon cov kuab tshuaj lom?
Methanol. Zoo li feem ntau hydrocarbon cov kuab tshuaj , methanol (methyl cawv) tuaj yeem ua rau muaj kev cuam tshuam ntawm kev hnov mob thiab ua rau muaj kev mob tshwm sim ntawm cov pa hauv huab cua hauv qab cov uas tsim cov kab mob hauv nruab nrog cev. Loj methanol tshuaj lom feem ntau yog txuam nrog ingestion.
Puas yog hydrocarbons tsim kev puas tsuaj rau ib puag ncig?
Ntawm lawv tus kheej, hydrocarbons tsim tsis muaj kev pheej hmoo. Txawm li cas los xij, thaum raug tshav ntuj thiab / lossis nitrogen oxides, lawv raug tshuaj lom neeg. Nws yog paub zoo tias emissions thiab kuab paug tsim los ntawm tib neeg beings nyob rau hauv no muaj hnub nyoog muaj txaus ntshai , thiab hydrocarbons ua ib feem loj ntawm cov khoom puas tsuaj.

Sinkholes yog qhov teeb meem loj cuam tshuam nrog thaj chaw karst (Gutiérrez, Parise, De Waele, & Jourde, 2014a). Subsidence cuam tshuam nrog kev loj hlob ntawm sinkholes tuaj yeem ua rau tib neeg tsim cov qauv, uas ua rau muaj kev cuam tshuam loj rau kev lag luam thiab kev sib raug zoo
Dab tsi ppm ntawm h2s yog qhov txaus ntshai?
Kev tuag yog sai, qee zaum tam sim. H2S qib ntawm 100 ppm thiab siab dua yog suav tias yog tam sim ntawd txaus ntshai rau lub neej thiab kev noj qab haus huv (IDLH). Dhau li ntawm nws cov khoom tsis zoo ceeb toom, H2S yog qhov txaus ntshai heev vim tias qib uas tuaj yeem tua tau qis dua li ntawm ntau lwm cov pa phem
