[I-Bis (2-chloroethyl) ether (CAS # 111-44-4)], i-dichloroethyl ether isetyenziswa ikakhulu njengesixhobo esiphakathi sokwenza imveliso yokubulala izitshabalalisi, kodwa ngamanye amaxesha inokusetyenziswa njengearhente yokusinyibilikisa kunye nokucoca. Iyacaphukisa ulusu, amehlo, impumlo, umqala nemiphunga kwaye ibangela ukungonwabi.
1. Itshintsha njani i-dichloroethyl ether kwimeko-bume?
I-Dichloroethyl ether ekhutshelwe emoyeni iya kusabela kunye nezinye iikhemikhali kunye nokukhanya kwelanga kuya kubola okanye kususwe emoyeni yimvula.
I-Dichloroethyl ether iya kubola yintsholongwane ukuba isemanzini.
Inxalenye ye-dichloroethyl ether ekhutshelwe emhlabeni iya kucocwa kwaye ingene emanzini aphantsi komhlaba, amanye aya kuboliswa ziibhaktheriya, kwaye elinye icala liyakumphumela emoyeni.
I-Dichloroethyl ether ayiqokeleli kwityathanga lokutya.
2. Iyintoni ifuthe le-dichloroethyl ether kwimpilo yam?
Ukubonakaliswa kwi-dichloroethyl ether kunokubangela ukungonwabi kulusu, amehlo, umqala kunye nemiphunga. Ukungenisa i-dichloroethyl ether ephantsi kunokubangela ukukhohlela kunye nempumlo kunye nomqala ungathandeki. Izifundo zezilwanyana zibonisa iimpawu ezifanayo nezo zibonwa ebantwini. Ezi mpawu zibandakanya ukucaphuka kolusu, impumlo, kunye nemiphunga, ukonakala kwemiphunga, kunye nokwehla kwenqanaba lokukhula. Kuthatha iintsuku ezi-4 ukuya kwezi-8 ukuba izilwanyana zaselebhu zisinde.
3. Imithetho nemigaqo yasekhaya neyangaphandle
I-Arhente yokuKhuselwa kokusiNgqongileyo yase-US (i-US EPA) icebisa ukuba ixabiso le-dichloroethyl ether emanzini echibi kunye nemilambo kufuneka ibekelwe umda ibe ngaphantsi kwe-0.03 ppm ukunqanda iingozi zempilo ezibangelwa kukusela okanye kukutya imithombo yamanzi engcolileyo. Naluphi na ukukhutshwa okungaphezulu kweepawundi ezili-10 ze-dichloroethyl ether kwimeko-bume kufuneka kwaziswe.
Indawo yokusebenza yaseTaiwan yongcoliseko lomoya ekumgangatho ovunyelweyo yoxinaniso ichaza ukuba umndilili ovumelekileyo woxinzelelo lwe-dichloroethyl ether (Dichloroethyl ether) kwindawo yokusebenza iiyure ezisibhozo ngosuku (PEL-TWA) yi-5 ppm, 29 mg / m3.
