Okhilimu bokwenza mhlophe, imaski yobuso, amafutha okunakekela isikhumba, udayi wezinwele… Namuhla, kunezinhlobonhlobo zemikhiqizo yezimonyo emakethe futhi ziyavela ngokungenamkhawulo, ezithandwa kakhulu abathandi bobuhle. Kodwa-ke, izimonyo ekuqaleni zisetshenziselwa ukunakekelwa kwesikhumba kanye nokuhlobisa isikhumba kanye nokuhlanza uma zisetshenziswa emzimbeni womuntu. Kodwa-ke, ukuphepha kwezimonyo kuyimfuneko ebaluleke kakhulu kunokusebenza kahle. Ngaphandle kwalokho, lapho umzimba womuntu uhlangana nezimonyo ezingaphansi kwekhwalithi, izingozi ezahlukahlukene zomzimba nezengqondo ezifana nokungezwani komzimba, ukulahleka kwezinwele, ukonakala kwesimo, kanye nomdlavuza zingase zenzeke.

Ngenxa yalokhu, iminyango eminingi ye-R&D yezinkampani zezimonyo kanye nama-laboratory ahlobene neminyango yokuhlola ikhwalithi azohlola izithako zezinto zokusetshenziswa zomkhiqizo wezimonyo, izinto zokupakisha, imikhiqizo eqediwe kancane, kanye nemikhiqizo eqediwe. Kungemva kokuhlola ikhwalithi nokuphepha ngokuhambisana nezindinganiso zokulawula ikhwalithi ezifanele lapho isitifiketi sokufaneleka komkhiqizo singakhishwa khona. Kungabonakala ukuthi ukuhlonza nokuhlola izimonyo elabhorethri sekuyisivikelo sokuqala sokuvikela impilo nokuphepha kwabathengi.
Ngakho-ke, yini okuqukethwe okuyinhloko kokuhlolwa kokuphepha kwezimonyo?

Kumkhiqizi wezimonyo ojwayelekile, ukuhlolwa kwensimbi esindayo, ukuhlolwa kwamagciwane, ukuhlolwa kokulondoloza, ukuhlolwa kokuqukethwe kwezinto ezisebenzayo, kanye nezinye izinto ezingavunyelwe nezivinjelwe zivame kakhulu ekuhlolweni nasekuhlaziyweni kwezinto ezinobuthi. Thatha i-chromium ye-heavy metal trace element njengesibonelo: i-chromium, i-chromic acid, i-chromium yensimbi, kanye ne-hexavalent chromium azikho ngqo ezimonyweni. Kodwa-ke, enkambisweni yokukhiqizwa nokuthuthukiswa kwezimonyo, kunezakhi zokungcola eziqukethe i-chromium ezitsheni zeglasi, njenge-Cr6+. Lokhu kudinga amalabhorethri ukuthi enze ukunqunywa nokuhlaziywa, bese ephakamisa izixazululo.

Kodwa-ke, uhambo lokuhlola ikhwalithi nokuphepha kwezimonyo elabhorethri alupheli lapha.

Inkinga yesibili ebhekene nezinkampani zezimonyo ukuthi iminyango efanele yokuphatha kahulumeni yenza ukuhlolwa okungahleliwe kwezimonyo ebezisetshenziswa ukuqinisekisa intuthuko enempilo nehlelekile yemakethe. Isibonelo, ukuthi i-lead, i-arsenic, i-mercury, inani lama-bacterial colony, i-p-phenylenediamine, amadayi asakazekayo, njll. emikhiqizweni yezimonyo idlula indinganiso, noma ngabe kukhona yini izinto ezivinjelwe njenge-meta-phenylenediamine kanye ne-phthalates. Ngezinye izikhathi le misebenzi yokuhlola iphathiswa amalabhorethri ezikhungo zokuhlola zangaphandle. Ngokufanayo, lokhu kumele kuqinisekiswe ngokuhlolwa kwesampula ngaphambi kokuba umbiko wokuhlolwa kwekhwalithi ukhishwe ezinkampanini zezimonyo kanye nemikhiqizo yazo ngokuhambisana nemigomo yezomthetho.

Akunzima ukucabanga ukuthi ukuze uthole inzuzo yangempela emncintiswaneni omkhulu wemakethe, njengoba ukuvama okusha kocwaningo nokuthuthukiswa kwezinkampani zezimonyo kuqhubeka nokwanda, lokhu kusho ukuthi umthwalo womsebenzi welebhu nawo uzokhula.

Kodwa-ke, kungakhathaliseki ukuthi ilabhorethri yenkampani yezimonyo, ilabhorethri yomnyango kahulumeni, noma ilabhorethri yokuhlola evela eceleni, umsebenzi wokuhlola izimonyo unzima kakhulu, futhi akunakugwenywa ukwandisa inani lemishini yokuhlola ukuze kuthuthukiswe ukusebenza kahle. Ikakhulukazi ukuqinisekisa ukunemba kwemiphumela yokuhlolwa, ukuhlanzeka kwezingilazi ezisetshenziswe ekuhlolweni kumele kuxazululwe kuqala. Njengoba sibhekene nale nselele, indima yeumshini wokuwasha ingilazi webhubhoratrisekube yinto ebaluleke kakhulu. Ngobaumshini wokuwasha izingilazi ozenzakalelayoayikwazi nje kuphela ukuhlinzeka ngokuhlanza okukhulu, okuhlakaniphile nokuphelele kwezinto ezingcolisayo zezingilazi zelebhu, kodwa futhi iphephile futhi inobungani nemvelo ngesikhathi sokusetshenziswa. Idatha efanele eqoshiwe ingasiza ekuhlinzekeni ireferensi ephumelelayo lapho kuhlolwa ikhwalithi yezimonyo.

Ungavumeli ukutotosa kukulimaze. Susa ukwengezwa okungekho emthethweni kwezinto ezingavunyelwe nezivinjelwe, futhi uqinisekise ukuthi imikhiqizo yezimonyo iyasebenza ngokwesayensi, ukuzinza kanye nokusebenza kahle. Lokhu kuphathelene namalungelo nokuphepha kwabathengi, futhi yilapho abakhiqizi nabalawuli begcwalisa khona izibopho zabo kanye nemithwalo yemfanelo. Isihluthulelo sokuphepha kwezimonyo sincike ekunembeni kwemiphumela yokuhlolwa kwelebhu. Kungokuthola ukuhlaziywa kwangempela kwezivivinyo kanye neziphetho lapho singaba nezwi langempela khona.
