Kuwonongeka kumawonekera nthawi zonse pantchito yabizinesi iliyonse yamafuta. Iwo ndi osiyana mu mtundu wawo komanso mulingo wangozi. Ndikofunikira kwambiri kuzikonza, komanso kusamalira bwino gawo lililonse lazinyalala. Akatswiri amagawira zinyalala malingana ndi momwe zimakhudzira chilengedwe chake komanso momwe zingakhudzire chilengedwe.
Kudziwitsa gulu lowopsa
Zinyalala zamtundu uliwonse komanso gulu lawo lowopsa zalembedwa mu Federal Classification Catalog. Gulu lowopsa limatsimikiziridwa ndi njira zotsatirazi:
- pakuyesa, zotsatira za mtundu wina wa zinyalala pazomera kapena nyama zimafufuzidwa;
- zinthuzo zimaphunziridwa mokwanira, kuwunika kwa poizoni kumachitika, ndipo kumapeto kumapangidwa molingana ndi zotsatira zowerengedwa;
- Kuzindikiritsa zowopsa kumachitika pogwiritsa ntchito njira zowerengera makompyuta.
Ponseponse, pali magulu anayi azinyalala omwe ali owononga chilengedwe, koma ngati asungidwa bwino ndikuwataya, zinyalala zilizonse zimawononga chilengedwe.
Gulu lowopsa limodzi
Kalasiyi imaphatikizapo zinthu zowopsa kwambiri zomwe zimawononga thanzi la anthu komanso chilengedwe. Izi ndi monga mitundu ya zinyalala zotsatirazi:
- mankhwala;
- nyali za fulorosenti;
- zinthu zonse zokhala ndi mercury.
Mukataya zinyalala za gulu limodzi loopsa, malamulo onse ayenera kutsatiridwa. Kulakwitsa kumodzi kungayambitse tsoka lachilengedwe ndikuwononga miyoyo. Asanagwiritse ntchito zinthuzi, ayenera kukhala opanda vuto, kenako adzaikidwa m'manda. Tsoka ilo, zinyalala tsopano zikuponyedwa kunja mosalamulirika, chifukwa chake, zinthu zambiri zomwe zimakhala ndi mercury nthawi zambiri zimaperekedwa kumalo omwe amataya zinyalala, zomwe zimawononga chilengedwe.
Gulu lowopsa la 2
Zinyalala m'gululi zimayambitsanso zovuta zachilengedwe komanso thanzi la anthu. Zinthu izi zikalowa m'chilengedwe, mawonekedwe a eco amakhala okhazikika patadutsa zaka 30. Kalasiyi ikuphatikizapo zinyalala zotsatirazi:
- mabatire oyambiranso;
- zidulo zosiyanasiyana;
- zinyalala kuchokera kumafakitale amafuta.
Gulu lowopsa la 3
Gulu ili limaphatikizapo zinyalala zowopsa pang'ono. Pambuyo pazowonongekazo chifukwa cha zinyalala zoterezi, chilengedwe chidzabwezeretsedwa mkati mwa zaka 10. Izi zikuphatikiza izi:

Makhalidwe a zinyalala za m'kalasi 4
Poganizira mwatsatanetsatane za zinyalala za gulu lazowopsa la 4, ziyenera kudziwika kuti kuchuluka kwawo kwangozi kumatsimikiziridwa ndi kuchuluka kwa zinthu zowopsa m'malo osungira zinyalala izi. Ndende yovomerezeka ndi 10 mg pa mita imodzi iliyonse. mita. Mulingo wakupha ndi 50,000 mg / sq. Zinthu zotere zimakhudza bwalo lokhala ndi utali wozungulira mamita 54. Zowopsa zazikulu zachilengedwe ndi moyo wamunthu zimachitika chifukwa cha zinthu zakhudzana ndi mafuta. Makampani onse osamalira zinyalala ayenera kusankha njira zawo zotayira malinga ndi zoopsa za zinyalalazo.
