Metsi ke ntho ea bohlokoa bophelong, ’me boleng ba ’ona bo ama ka ho toba boiketlo ba rōna le tikoloho. Mefuta e 5 ea mantlha ea boleng ba metsi e bapala karolo ea bohlokoa ho eleheng polokeho ea metsi le ho etsa bonnete ba hore a loketse merero e fapaneng. Sehloohong sena, re tla hlahloba lintlha tsena ka botlalo, re fane ka lintlha le tsebo ea litsebi ho u thusa ho utloisisa bohlokoa ba tlhahlobo ea boleng ba metsi.
5 Mefuta e ka Sehloohong ea Mekhahlelo ea Boleng ba Metsi
Tlhahlobo ea boleng ba metsi e kenyelletsa ho lekola likarolo tse fapaneng tse khethollang hore na a tšoaneleha bakeng sa ts'ebeliso e itseng. Mefuta e 5 ea mantlha ea boleng ba metsi ke:
1. Mekhahlelo ea 'mele
Mekhahlelo ea 'mele e bua ka litšobotsi tse bonoang tsa metsi tse sa kenyelletseng tšebetso ea lik'hemik'hale. Lintlha tsena li fana ka leseli mabapi le chebahalo ea metsi, mocheso le likarolo tse ling tsa 'mele. Lintlha tsa bohlokoa tsa 'mele li kenyelletsa:
Turbidity: Turbidity e lekanya maru a metsi a bakoang ke likaroloana tse emisitsoeng. Maemo a phahameng a moferefere a ka bontša tšilafalo kapa ho phalla ha seretse.
Mocheso: Mocheso oa metsi o ama tikoloho ea metsing 'me o ka ama ho qhibiliha ha oksijene le lintho tse ling.
Mmala: 'Mala oa metsi o ka senola boteng ba lintho tsa tlhaho kapa lintho tse silafatsang.
2. Mekhahlelo ea lik'hemik'hale
Mekhahlelo ea lik'hemik'hale e lekola boteng le khatello ea lintho tse fapaneng tsa lik'hemik'hale metsing. Lintho tsena li ka tsoa mehloling ea tlhaho kapa mesebetsing ea batho. Likarolo tsa bohlokoa tsa lik'hemik'hale li kenyelletsa:
pH: Maemo a pH a bontša asiti ea metsi kapa alkalinity, e amang bokhoni ba eona ba ho tšehetsa bophelo ba metsing.
Oxygen e qhibilihisitsoeng (DO): DO e bohlokoa bakeng sa lintho tse phelang metsing, 'me maemo a eona a bontša boleng ba metsi le boteng ba tšilafalo.
Limatlafatsi: Maemo a limatlafatsi, joalo ka nitrogen le phosphorus, a ama boleng ba metsi mme a ka lebisa ho lithunthung tse kotsi tsa algal.
Heavy Metals: Limetale tse boima, joalo ka loto le mercury, li chefo 'me li ka silafatsa mehloli ea metsi.
3. Mekhahlelo ea likokoana-hloko
Mekhahlelo ea baeloji e kenyelletsa boithuto ba lintho tse phelang tse teng metsing le tlhahlobo ea bophelo bo botle le mefuta-futa ea tsona. Li-parameter tsa bohlokoa tsa baeloji li kenyelletsa:
Likokoana-hloko le Likokoana-hloko: Boteng ba baktheria bo bontša monyetla oa mafu a bakoang ke metsi.
Likokoana-hloko tsa Aquatic Macroinvertebrates: Liphoofolo tsena li sebetsa e le matšoao a boleng ba metsi le bophelo bo botle ba tikoloho.
4. Radiological Parameters
Mekhahlelo ea mahlaseli a kotsi e shebana le ho metha maemo a mahlaseli ka metsing, a ka hlahisoang ke mehloli ea tlhaho kapa mesebetsi ea batho. Likarolo tse kholo tsa radiology li kenyelletsa:
Alpha, Beta, le Gamma Radiation: Ho hlahloba maemo a mahlaseli a kotsi ho netefatsa tšireletso ea metsi le ho sireletsa khahlanong le ho pepeseha ho kotsi.
5. Organic Parameters
Mekhahlelo ea lintho tse phelang e sekaseka boteng ba metsoako ea lintho tse phelang metsing, e ka hlahang mehloling ea tlhaho kapa mesebetsing ea batho. Lintlha tsa bohlokoa tsa organic li kenyelletsa:
Likokoana-hloko le Likokoana-hloko: Metsoako ena e ka silafatsa metsi ’me ea ba le liphello tse mpe bophelong ba metsing le bophelong ba batho.
Meriana ea Meriana: Ho ba teng ha mesaletsa ea meriana ka metsing ho ka baka likotsi tse ka bang teng.
Bohlokoa ba Tlhahlobo ea Boleng ba Metsi
Tlhahlobo ea boleng ba metsi e bohlokoa ka mabaka a fapaneng, ho kenyelletsa:
Bophelo bo Botle ba Sechaba: Ho netefatsa metsi a nooang a bolokehileng le ho thibela mafu a bakoang ke metsi ho bohlokoa bakeng sa bophelo bo botle ba sechaba.
Paballo ea Tikoloho: Ho utloisisa boleng ba metsi ho thusa ho sireletsa tikoloho ea metsing le ho boloka mefuta-futa ea lihloliloeng.
Temo le Indasteri: Metsi a boleng a bohlokoa bakeng sa ho nosetsa, mekhoa ea indasteri, le ho boloka mekhoa e metle ea temo.
Boithapollo: Metsi a sireletsehileng le a hloekileng a etsa hore ho be le lintho tse fapa-fapaneng tsa boikhathollo tse kang ho sesa le ho sesisa liketsoana.
FAQs
Na ho na le mehloli ea tlhaho ea litšepe tse boima ka metsing?
E, litšepe tse ling tse boima li etsahala ka tlhaho metsing ka lebaka la mekhoa ea jeoloji. Leha ho le joalo, mesebetsi ea batho e kang ho ntšoa ha liindasteri le meepo li ka phahamisa maemo a tsona haholo, e leng se lebisang tšilafalong.
Tšilafalo ea limatlafatsi e ama boleng ba metsi joang?
Limatlafatsi tse feteletseng, tse kang nitrogen le phosphorus, li ka baka eutrophication, e leng se lebisang ho holeng ha lithunthung tse kotsi tsa algal. Lipalesa tsena li fokotsa maemo a oksijene 'me li lematsa bophelo ba metsing.
Ke likotsi life tsa bophelo tse amanang le metsi a nooang a nang le chefo e bolaeang likokoanyana?
Metsi a silafalitsoeng ke chefo e bolaeang likokoanyana a ka baka likotsi tse tebileng tsa bophelo bo botle, ho kopanyelletsa le mathata a methapo ea kutlo le khōlo, mofetše le mathata a ho ba le bana.
Liparamente tsa baeloji li thusa joang ho lekola boleng ba metsi?
Mekhahlelo ea baeloji, joalo ka li-macroinvertebrates tsa metsing, li sebetsa joalo ka li-bioindicators. Boteng ba tsona, bongata, le ho se tšoane ha tsona li bontša bophelo bo botle ba tikoloho.
Litlamorao tsa maemo a phahameng a lets'olo ka metsing ke afe?
Maemo a phahameng a seretse a ka bontša tšilafalo le ho phalla ha seretse. E ka boela ea fokotsa ho kenella ha leseli, ho ama photosynthesis ea limela tsa metsing le ho senya libaka tsa tlhaho.
Hobaneng ho le bohlokoa ho beha leihlo li-parameter tsa radiological metsing?
Litekanyetso tsa mahlaseli a kotsi li thusa ho tseba tšilafalo e ka bang teng, ho netefatsa polokeho ea metsi le ho fokotsa likotsi tsa bophelo bo botle.
Qetello
Ho bohlokoa ho utloisisa mefuta e 5 ea bohlokoa ea boleng ba metsi bakeng sa ho lekola polokeho ea metsi le ho baballa tikoloho. Tlhahlobo ea kamehla ea mekhahlelo ena e netefatsa hore mehloli ea metsi e lula e hloekile ebile e loketse merero e fapaneng. Ka ho nka mehato e tiileng ea ho boloka boleng ba metsi, re ka sireletsa bophelo ba rōna le ho sireletsa mehloli ea bohlokoa ea lefatše.
