Inyaniso kukuba nayiphi na into phantsi kweemeko ezithile ingaba yingozi. Naliphi na lingaba nefuthe elithile elibi kwimpilo yabantu, kukho umbuzo wenzalo okanye uxinaniso, ubunzulu kunye nobude bokubhenca. Ngokomzekelo, amanzi aqhelekileyo evela emithonjeni enzulu engcolileyo neekhemikhali ezinobungozi ngokuqhelekileyo aqokelelwa kwiindawo ezingezantsi zomhlaba. Kulapho kubandakanywa izityalo kwaye kunye kunye nabo kungena emzimbeni wethu. Ngoko amanzi (ngokuchanekileyo, i-toxins kuyo) ngexesha elifutshane linokuba nemiphumo ebalulekileyo kwimpilo yabantu. Ukongeza, i-oksijeni yokunika ubomi, kwiimeko ezithile kunye neemeko, i-toxin eyingozi. Umoya, ngakumbi kwiidolophu ezinkulu, ungcolileyo yizinto ezininzi eziyingozi ezisongela impilo kwaye kaninzi-ubomi.
Inetyhefu inokufumaneka ngokubanzi kunye neetyule yetyuwa (i-sodium chloride) kunye ne-glucose, eqinisweni, ukuba idliwa ngobuninzi obukhulu. Amanzi olwandle olutyebi olutyuwa ayilungele ngokupheleleyo ukusela ngokuchanekileyo ngenxa yokuxinwa okuphezulu kwezi saliti, ezinobuthi obuphezulu.
Amanzi adibeneyo ayingozi kakhulu kwimpilo yakho. Ukuphazamiseka kukuba yinto yamanzi ecocekileyo, kodwa oku kuyingozi kuyo. Ayinayo nayiphi na izithako ezongezelelweyo eziyimfuneko ebomini. Amanzi anjalo ayinakunqandwa ngumzimba, kwaye ngokusetyenziswa rhoqo kukutyhefu.
Ngokufanelekileyo, iigesi ezinobungcipheko azizona zityhefu kubantu. Ngoko-ke, i-nitrogen (iqela eliphambili lomoya), i-hydrogen, okanye igesi ene-hydrocarbon e-aliphatic elula, efana ne-methane, i-ethane ne-propane, ayiyingozi. Kodwa xa umntu ohlala emagumbini angenawo umoya aphefumula i-gesi engenakushintsi rhoqo-ngokubhekiselele ekunyuseni kwendawo yokugxininisa emoyeni kwigumbi - ityhefu ngokwayo. Ngaloo ndlela, i-oksijini iyaxoshwa emoyeni-iimpawu eziqhelekileyo zesicetychemical body of body. Ngoko-inkolelo, into engeyona into enobuthi iyinto echaphazelayo kwimpilo yabantu.
Ingqiqo yobuthi bezinto ezahlukeneyo ngokuhambelana nolwazi lwangoku luqondwa kakhulu kuninzi ngaphambili. Uluhlu lwezinto ezinobungozi aluphelelanga kwiindawo ezidumileyo "zembali" ezifana ne-arsenic, i-cyanide, i-strychnine, i-curare, i-almayid i-hemlock (i-hemlock), inyoka, inyosi equlethwe kwi-fungi. Kuxhaswa ngezinto ezininzi, kwiimeko ezithile kunye neemeko, ziba yingozi kwiindawo ezikhuselekileyo. Nangona abanye bangasongela impilo kunye nangobomi bomntu.
Umzekelo omhle wezinto ezinjalo, ogqithiswa kakhulu kwiindlela ezahlukeneyo, i-ethanol. Yiyo yinto enokutyhelwa ngetyhefu ngosuku olunye. Ukusetyenziswa kwamanani ekhethekileyo ethanol kumayeza kukhuselekileyo kubantu abaninzi. Ukugqithisa umlinganiselo ofanayo okanye ukudibanisa namanye amachiza amachiza kunye nezinye iimeko ezinobungozi. Ngenxa yeengxaki zokusebenzisana kweziyobisi, i-ethanol ingabangela iimpawu ezinzulu kakhulu ngenxa yokulimala kwizitho kunye neenkqubo kunye nokuchaphazela umsebenzi wazo.
Kufuneka kuphawulwe ukuba kukho abantu abaneempawu ezibonakalayo ezibangelwa imfuyo kwiziphumo ezinobungozi zezinto ezibonwa njengezityhefu. Ukubeka nje, abakwazi ukuzityhefu ngokwenza ubuthi nobunye umntu. Kunzima ukusho ukuba ngaba "ukukhulelwa" okunjalo kuvela ngenxa yokuqhagamshelana rhoqo ne-toxin okanye ukuba kukho esinye isizathu. Enyanisweni, phantsi kweemeko ezithile, iindlela zokuziphendulela ezichanekileyo zingabonakala, kodwa akukho zizathu zenzululwazi zolu hlobo. Ngokulula, kukho abantu abangenakukhathazeka, ngokomzekelo, ukuba inyoka inyoka. Okanye abo banokunyamezela ngokulula iindleko ezinkulu ze-ethyl yotywala (ngendlela yayo, kwakhona, i-toxin enamandla).
Inyaniso kunye neengcamango malunga nezinto ezinobuthi
Ulwazi oluntu malunga nento eyingozi kwimpilo yabantu kwaye engabangela ingozi enkulu kubonakala ngokunyanisekileyo nokunyuka. Kodwa ke akwanele, ngokukodwa phantsi kweemeko ezithile, xa, ngelanga, abantu badla ngokulahlekiswa.
Ngokomzekelo, kukho uluvo olusasazekayo (nakwabanye oogqirha) ukuba i-mercury yensimbi yingozi yingozi. Amaxesha amaninzi abazali abaphethe i-thermometer ye-mercury endlini yabo bayesaba ukuba baya kuphuka baze babuthabathe umntu ngamnye ngosuku. Kodwa ngelo xesha kwi-thermometers enjalo akukho zinyithi zetsimbi! Kukho i-mercury evamile yamanzi, apho iimpompo zaso zingabungozi, kodwa kuphela xa zixhaswa ngemimandla emikhulu kunye nexesha elide. I-mercury yeMetric, ngokuchaseneyo nayo, inobungozi nakwii-microdoses, ezinjengeemveliso ezininzi ezingenangqungquthela zetsimbi etyhidiweyo.
Ubunobuthi beemveliso ezithile zichongiwe ngabantu abaninzi kwaye zivavanywa ngokupheleleyo. Umzekelo, ngokusekelwe kwintetho yabo, ukunambitheka nokubonakala. Abantu abaninzi bakholelwa ukuba babambe i-mushroom enetyhefu ngenxa yokuba ibuhlungu, okanye ngenxa yokuba i-hat of their hat does not darken ngenxa yokucinezelwa okanye ngaphantsi kwefuthe lokukhanya. Enyanisweni, ukuba i-fungus iyabrakra okanye ayikho, iyancipha phantsi kwefuthe lokukhanya. Ukusuka kwindlela yokujonga i-toxicological view, konke oku akunakwenzeka! Ubunobuthi befungi buxhomekeke kubukho bezinto ezinobuthi kuzo, ezo iingcambu zomntu okanye ezinye iindlela ezilula ezingenakuzibona.
Amaxesha amaninzi kwenzeka ukuba abanye abantu baphazamisa ngokugqithiseleyo izixhobo ezinobuthi ezine-ethylene glycol. Umzekelo, i-brake fluid, eyingozi yetyhefu. Phantse kuzo zonke iimeko, umntu wayeqinisekile ukuba ayinayo inetyhefu yelwelo, ngokukodwa, ngokuchanekileyo kuba yayimnandi kwintetho.
I-Denaturates icingelwa ukuba ingenye yezona zibuhlungu kakhulu kunobungozi kubantu. Enyanisweni, zinobutyhefu njengenye iifom e-alcohol.
Igesi yendalo, esetyenziswa ngokubanzi namhlanje, ithathwa njengetyhefu kakhulu, ngelixa ukukhululwa kombane ongapheliyo we-carbon monoxide kwenza kube yingozi kakhulu kwimpilo nobomi. I-gesi yendalo ngokwenene yimbangela enye, okokuqala iyingozi kubantu-iqokelela kwiindawo ezidibeneyo. Ukongeza kokususa i-oksijeni kuyo, inokuphazamiseka ngokukhawuleza ngamandla amakhulu. Iphunga elimnandi lidla ngokubangela ukwesaba nokukhokelela kwizigwebo zobuxoki malunga nesichengiso sotywala. Kodwa akusiyo yonke into evumbayo inukayo inetyhefu! Bambalwa abantu bayazi ukuba i-carbon monoxide ekhutshwe kwi-gesi yendalo ingapheliyo, kodwa amaxesha amaninzi ayingozi. Yiyo kanye into onokuyenza ubuthi - olunye usuku luphela nje iiyure ezimbalwa zichasene. Oku kwanele ukufumana i-dose ebulalayo.
Nangona kukho ukungaphumeleli kunye neengcambu zolwazi ezifumanekayo kuluntu lwangoku, abantu bayazi kakhulu ngeengozi zobuthi bezinto ezihlukahlukeneyo. Kodwa ngamanye amaxesha kukho ezininzi iindinyana eziphosakeleyo kule ndawo. Kwimeko nayiphi na imeko, ukuqaphela isongelo kulunge ngaphezu kokukhanyela kwayo.
