Iimpawu zetyhefu

Isizathu semeko engafanelekanga yempilo sinokuchaphazeleka kakubi kwezinto ezinobungozi. Oku kubunobuthi bomzimba. Kubalulekile ukucacisa umthombo weetyeki ngexesha - kuba nganye ihora elilahlekileyo lingakhokelela kwimiphumo engapheliyo. Ukwenza oku, kufuneka ukwazi ukwahlula iimpawu zetyhefu ngemveliso ethile okanye iikhemikhali. Ezinye iziganeko eziqhelekileyo zetyhefu ziza kuxutyushwa kwimiba yethu yanamhlanje.

Imiqondiso ye-carbon monoxide yetyhefu

I-carbon monoxide ayinayo umbala okanye iphunga, lisebenza emzimbeni ngokukhawuleza, kodwa lungaqondakali. Ngoko ke, kunzima ukufumanisa isizathu sokutyhefuza kuphela ngeempawu. I-Carbon monoxide ityhefu ingenzeka ukuba imeko yezempilo ibuhlungu emva kokuba igumbi, apho:

kwakukho umtshiso womlilo;
ukufakwa okungagunyaziswanga kwezixhobo zokufudumala kwegesi;
umgangatho osweleyo okanye ukukhishwa kwamanzi;
kwakukho ukukhishwa kwamanzi gesi.

Ubungozi be-carbon monoxide ubuthi buphezulu kakhulu kwimveliso yamakhemikhali, kuba i-carbohydrate oxide yinto eqhelekileyo yokutsha kwezinto eziphilayo.

Iimpawu zobutyhefu be CO:

entloko;
isicefe
ukuphefumula okufutshane;
ukulahlekelwa kwengqondo;
i-cyanosis yolusu.

Izimpawu ezifanayo zifumaneka xa i-methane inetyhefu. Eli gesi lisetyenziswe njengamafutha. Yena, naye, akanalo umbala okanye ahogela. Kodwa kwi-methane yasemakhaya (i-gas stoves, boilers kunye namakholomu), i-deodorant-mercaptan-ifakwe ngefrimbi ephosakeleyo. Ngoko ke, ukuqaphela ukuvuza kwemethane kulula kakhulu.

Imiqondiso ye-mercury enetyhefu esuka kwi-thermometer

I-Mercury yintsimbi yesinyithi, inobungozi kumzimba womntu nayiphi na inxibelelwano. I-acute mercury poisoning iyenzeka xa inhalisa inani elikhulu lemfucumfucu okanye ngokungeniswa kwe-mercury ecocekileyo kunye neeriti zayo. Nangona umonakalo kwi-thermometer ye-mercury, iibhola ezincinane ezihambayo zingakwazi ukufikelela kwi-membrane ye-mucous yamehlo okanye yomlomo. Uqhagamshelwano olunjalo nobutyhefu lukhuthaza ukungena ngokukhawuleza kweemlekyuli ze-mercury zibe yigazi. Ngelo xesha, umphunga wentsimbi yesinyithi ifakwa. Ekubeni umlinganiselo we-mercury kwi-thermometer ayinelanga ngokwaneleyo ukutyhefuza, iimpawu zokuxhatshazwa zingenakwenzeka ngokukhawuleza. Iimpawu ze-mercury enetyhefu:

intsimbi yensimbi emlonyeni;
isicefe
ukuphazamiseka kwengxaki;
ukuphuma kweentlobo;
salivation;
ukuphulwa komnatha wesiseko.

Iimpawu zokutyhefuza ngamakhowe

Iifomsi eziqulethwe ekudleni, ngamanye amaxesha zikhupha i-poisoning. Kwaye enye yokutya eyingozi kakhulu i-mushroom. Ewe, sithetha ngamakhowa anobuthi. Kodwa banokwenza ngokuqinileyo "ukuqhayisa" amakhowe asetyenziswayo, okokuba abavumi be-mushroom abanamava ngamanye amaxesha benza iimpazamo. Kwanele enye ye-toadstool eluhlaza ukuze ungene epanini ngamakhowe athengwayo, njengoko isitya siba yingozi ebomini. Iimpawu zobutyhefu ngefungi zihluke ekutyeni kokutyhefu kokutya ngokungabikho kokunyuka kwamaqondo okushisa kwaye kunokuvela kwiiyure ezingama-2 ukuya kwezi-24 emva kokusetyenziswa kwemveliso. Iimpawu zokungenisa i-toxins engumngcwabo emzimbeni:

intloko;
isicefe
ukuhlanza okungapheliyo;
isifo sohudo okanye ukuqhawuka;
salivation;
ukuphulwa komnatha wesiseko.

Kukho ukulahlekelwa ngokukhawuleza kwamanzi, kukho ukungcola. Ngoko ke, kwiimpawu zokuqala kwanoma yiyiphi inetyhefu kuyimfuneko ukuba uzalise ngokukhawuleza ukulinganisela kweseyile yelwandle. Xa kunobuthi obunetyhefu ngamakhowe, isibindi kunye nezintso zithatha inzima kakhulu. Ngonyango olungonelanelekanga, utywala olunzulu kunye nokungafihleki ngokuthe tye kungenzeka ngosuku lwesibini. Isiphumo salolu phuhliso sisiphumo esibulalayo.
