Uhlobo oluqhelekileyo lwesiselo esinxilisayo lwezinyango kwiindlela zonyango lubangela ubuthi. Kwaye abantu abangahambelani nomsebenzi kwimveliso okanye kusetyenziswe le nkunkuma bahlala bebonakaliswe kule nzala ngokukhupha uthuli olunobuthi okanye i-fumes.
Iimpawu kunye neempawu zetyhefu ekhokelayo
Ukubonakaliswa kwezonyango zeengxaki ezichazwe zihambelana nokunyuka kwenkxininiso yensimbi enzima egazini (ngaphezu kwe-800-100 μg / L ye-biological fluid). Utyhefu olunzulu kunye nomphunga okhokelayo okanye uthuli oluqulethwe yilezi zixhobo zihamba kunye neempawu:
- ukukhulelwa kwegazi;
- intlungu ebuhlungu esiswini;
- i-peripheral neuropathy nge-demyelination ngokukhawuleza ye-neurons ende;
- intloko;
- imemori kunye nokukhathazeka kwengqondo.
Kukho kwakhona i-subclinical chronic lead utyhefu, apho uxinaniso lwesinyithi egazini lukhula ngokuthe ngcembe kunye nexesha lokungabalulekanga. Njengomthetho, le fomu yesifo iyingqayizivele kubantu abasebenza kumashishini amakhemikhali basebenzisa izixhobo zokuhamba. Unempawu ezilandelayo:
- umonakalo wezintso;
- uxinzelelo lwegazi oluphezulu;
- ukuphazamiseka kwenkqubo ye-nervous system;
- kunqabile - incephalopathy .
Ukunyangwa kwetyhefu
Okokuqala, susa umthombo woqhagamshelwano ngamaphule kunye nothuli oluqukethe. Ukwelashwa okuqhubekayo kusekelwe ekungeniseni kumzimba weziyobisi ezenza ifomicomplex complexes kunye ne-metal-compounds ezivimbela umphumo ombi wequmrhu kunye negalelo ekupheliseni kwayo. Ukwenza oku, i-calcium salts i-dimercaprol, i-EDTA kunye ne-cuprin (D-penicillamine) isetyenzisiweyo, kwaye i-agent entsha, i-dimercaptosuccinic acid, iphinda ihlolwe.
Ubuchule bokunonyango bubekwe emva kokuthelekisa isixa semithi esicatshulwayo kunye nesiphelo, sichithwa kumchamo. Ulwaphulo lubonwa ngempumelelo xa i-1 mg ye-akhawunti yezilwanyana ezinzima ngaphezu kwe-1 μg yokukhokela kumchamo okhutshwe emini.
Ngobutyhefu obukhulu kunye nophuhliso lwe-encephalopathy enzima, kucetyiswa ukulawula ezimbini izidakamizwa kanyekanye - ityuwa ye-calcium ye-EDTA ne-Dimercaprol. Ubukho be -edema ye- cerebral buquka ukusetyenziswa kweDexamethasone kunye neMannitol.
Inkqubo epheleleyo yeyeza unyango lweentsuku ezingama-5, kodwa ukuba kuyimfuneko, inokuphindwa emva kwekhefu elifutshane.
