Imisebenzi yezimayini idlala indima ebalulekile ekuthuthukisweni komnotho ngokuhlinzeka ngezinto zokusetshenziswa zezimboni ezahlukene, ukudala imisebenzi, kanye nokwandisa imali engenayo yesifunda neyesizwe. Kodwa-ke, naphezu kwale minikelo, ukumbiwa kwezimayini kunemiphumela emibi kakhulu emvelweni nasempilweni yomphakathi, ikakhulukazi kubahlali abahlala eduze kwezindawo zezimayini. Le miphumela yezempilo ingenzeka ngezindlela ezahlukene, okuhlanganisa ukungcola komoya, amanzi, kanye nomhlabathi, izinguquko zemvelo, kanye nezingcindezi zenhlalo-zomnotho ezihambisana nokuba khona kwezimboni zokukhipha izinto. Lesi sihloko sihlola umthelela wemisebenzi yezimayini empilweni yomphakathi, siqokomisa izinhlobo zemiphumela, amaqembu asengozini, kanye nezinyathelo zokunciphisa ezingaba khona.
1. Izindlela Zokuchayeka: Kungani Ukumba Kuyingozi Yempilo?
Imiphumela yezempilo yokumba ayiveli ngaso sonke isikhathi ngokushesha noma ngokuqondile. Amacala amaningi avela ekuchayekeni isikhathi eside ezintweni ezingcolisayo. Izindlela eziyinhloko zokuchayeka ngokuvamile zifaka:
1. Umoya: Uthuli lwezimayini, ukukhishwa kwemishini esindayo, ukushisa, kanye nezinqubo zokucubungula amaminerali kungakhiqiza izinhlayiya ezincane (PM2,5 kanye ne-PM10), amagesi ayingozi (SO₂, NOx), kanye nomhwamuko othile wensimbi.
2. Amanzi: Imfucuza yezimayini ingangena emifuleni, emachibini, noma emithonjeni yezakhamuzi ngokusebenzisa amanzi emvula noma ukuvuza okuvela emachibini asezindaweni ezimanzi.
3. Uchungechunge Lomhlabathi Nokudla: Izinsimbi ezisindayo zingahlala enhlabathini futhi zimuncwe yizitshalo, bese zingena ochungechungeni lokudla kwabantu ngemifino, izinhlanzi noma imfuyo.
4. Umsindo nokudlidliza: Imisebenzi yokubhoboza nokuqhuma ingabangela ukucindezeleka, ukuphazamiseka kokulala, kanye nengozi yezingozi.
5. Ezenhlalo kanye nokuziphatha: Ukufuduka kwabasebenzi, izinguquko endleleni yokuphila, kanye nezingxabano zomhlaba kungabangela izinkinga zempilo yengqondo kanye nezifo ezithelelanayo.
2. Umthelela Empilweni Yokuphefumula
Omunye wemiphumela evame kakhulu yezimayini izinkinga zokuphefumula. Uthuli oluvela ekuhlanzeni umhlaba, ukuthuthwa kwezinto, ukuchotshozwa kwamatshe, kanye nokuhamba kwezimoto ezisindayo kungandisa amazinga ezinhlayiya emoyeni. Ukuchayeka othulini isikhathi eside kuhlotshaniswa nalokhu:
– ISPA (Acute Respiratory Tract Infection), ikakhulukazi ezinganeni nakubantu asebekhulile.
– Isifuba somoya kanye ne-bronchitis engapheli, okungaba kubi kakhulu ngenxa yokungcola komoya.
– I-Pneumoconiosis, njenge-silicosis kubasebenzi bezimayini abachayeke kakhulu ku-silica.
– Ukungasebenzi kahle kwamaphaphu, okuvame ukunganakwa kuze kube yilapho isimo siba sibi kakhulu.
Le miphumela ivame ukwanda lapho ukulawulwa kothuli kuncane, isibonelo akukho ukuchelela emigwaqweni yezimayini, akukho ukuqapha ikhwalithi yomoya , noma izindawo zokuhlala ziseduze kakhulu nendawo yokusebenza.
3. Ukungcoliswa Kwamanzi Nezifo Ezilandelayo
Amanzi ahlanzekile ayisidingo esiyisisekelo. Lapho ikhwalithi yamanzi yehla ngenxa yemisebenzi yezimayini, impilo yomphakathi nayo iyasongelwa. Inkinga eyodwa ebalulekile ukugeleza kwamanzi emayini ene-asidi, okungamanzi aba ne-asidi kakhulu ngenxa yokusabela kwamakhemikhali kwamaminerali e-sulfide emoyeni namanzi. Ukugeleza kwamanzi emayini ene-asidi kungancibilikisa izinsimbi ezisindayo futhi kungcolise imifula namanzi angaphansi komhlaba.
Ngenxa yokungcoliswa kwamanzi, abantu bangabhekana nalokhu okulandelayo:
– Uhudo, uhudo, kanye nezifo zokugaya ukudla ezibangelwa amanzi okuphuza angcolile.
– Izifo zesikhumba ezifana nokulunywa, i-dermatitis, kanye nokucasuka okubangelwa ukuthintana ngqo lapho ugeza noma ugeza.
– Ubuthi bensimbi buyenzeka lapho izinsimbi ezisindayo ezifana ne-mercury (Hg), i-lead (Pb), i-arsenic (As), kanye ne-cadmium (Cd) zingena emzimbeni ngamanzi noma enhlanzini.
Kwezinye izindawo, ukumbiwa kwegolide elincane kusebenzisa ne-mercury enqubweni yokuhlanganisa. Uma ishiywa ingalawulwa, i-mercury ingangcolisa amanzi futhi iphele emoyeni, okwandisa ingozi yezinkinga zezinzwa, ikakhulukazi ezinganeni ezisanda kuzalwa nasezinganeni.
4. Izinsimbi Ezisindayo Nemiphumela Engapheli Yesikhathi Eside
Imiphumela ekhathaza kakhulu ivame ukuba yesikhathi eside, ikhula kancane, futhi kunzima ukuyibona ngaphandle kokuhlolwa kwezempilo okukhethekile. Izinsimbi ezisindayo namakhemikhali okumbiwa phansi angabangela:
– Izinkinga zemizwa kanye nokukhula ezinganeni, isibonelo ngenxa yokuchayeka ku-lead noma i-mercury. Izingane zingaba nenkinga yokufunda enciphile, ukuphazamiseka kokuziphatha, kanye nokubambezeleka kokukhula.
– Izinkinga zezinso nesibindi, ngoba lezi zitho zisebenza ukuhlunga ubuthi emzimbeni.
– Izinkinga zokuzala, okuhlanganisa nezinkinga zokukhulelwa kanye nengozi yokuzalwa kwezingane ezinesisindo esiphansi.
– Ingozi yomdlavuza, ikakhulukazi uma ivezwa ku-arsenic noma ezinye izinto ezibangela umdlavuza isikhathi eside.
Ngenxa yokuthi izimpawu zokuqala zingaba ezingaqondile (ukukhathala, isiyezi, isicanucanu), izimo eziningi zelashwa sekwephuzile. Ngakho-ke, ukuqapha impilo njalo kanye nokuhlolwa kwe-biomarker (isib. amazinga e-metal egazini noma emchameni) kubalulekile ezindaweni ezinobungozi obukhulu.
5. Impilo Yengqondo kanye Nomthelela Wezenhlalo
Ngaphezu kokungcola, ukumba izimayini kuvame ukubangela izinguquko ezinkulu emphakathini emiphakathini ezungezile. Lezi zinguquko zingathinta impilo yengqondo, isibonelo:
– Ukucindezeleka okubangelwa izingxabano zomhlaba kanye nokufinyelela ezinsizeni, okuhlanganisa umhlaba wezolimo, amahlathi kanye namanzi.
– Ukukhathazeka ngekusasa, lapho izindlela zokuphila zendabuko ziphazanyiswa ukwehla kwekhwalithi yenhlabathi namanzi.
– Ukuphazamiseka kokulala okubangelwa umsindo kanye nomsebenzi wamahora angama-24 kwezinye izimayini.
– Izinkinga zomphakathi ezikhulayo njengokusebenzisa kabi utshwala noma izidakamizwa ezindaweni ezibhekene nokuthutheleka kwabantu abavela kwamanye amazwe kanye nezinguquko zomnotho ezizumayo.
Impilo yomphakathi ayikona nje ukungabikho kokugula ngokomzimba; ihlanganisa nenhlalakahle yengqondo kanye nokuzwana komphakathi. Lapho izakhiwo zomphakathi zinyakaziswa, imiphumela ingadlulela ebudloveni basekhaya, ekuyekeni isikole, kanye nobugebengu.
6. Amaqembu Asengozini Kakhulu
Imiphumela yezimayini ayisakazwanga ngokulinganayo; amanye amaqembu asengozini enkulu, okuhlanganisa:
– Izingane, ngoba izitho zazo zomzimba zisakhula futhi zizwela kakhulu ubuthi.
– Abesifazane abakhulelwe, ngoba ukuchayeka ezintweni ezisindayo kungathinta ingane esanda kuzalwa.
– Asebekhulile kanye nabantu abanezifo ezingamahlalakhona, abasengozini enkulu yezinkinga ngenxa yokungcola komoya namanzi.
– Izisebenzi zasezimayini, ikakhulukazi uma zingatholi imishini yokuzivikela eyanele (i-PPE) noma zisebenza amahora amaningi kakhulu.
– Imiphakathi ehola kancane, evame ukuba nobunzima bokuthola amanzi ahlanzekile, izinsizakalo zezempilo, kanye nolwazi oluphathelene nezingozi.
7. Imizamo Yokuvimbela Nokunciphisa Ubunzima
Ukunciphisa umthelela wezimayini empilweni yomphakathi kudinga ukubambisana phakathi kohulumeni, izinkampani kanye nezakhamuzi. Ezinye zezinyathelo ezibalulekile zifaka:
1. Ukuphoqelelwa kwe-AMAL kanye ukuqapha imvelo
Uhulumeni udinga ukuqinisekisa ukuthi yonke imisebenzi yezimayini ihlangabezana nezindinganiso zokuhlaziywa komthelela wemvelo (i-AMDAL), okuhlanganisa nokuqapha okusobala kwekhwalithi yomoya, amanzi kanye nomhlabathi.
2. Ukuphathwa kwemfucuza kanye nezindawo zokulahla indle eziphephile
Amachibi okudonsa amanzi kumele aklanywe ngokwezindinganiso, aqashwe ngokucophelela, futhi abe nezinhlelo eziphuthumayo zokuvimbela ukuvuza noma ukuqhekeka.
3. Ukulawulwa kothuli nokukhishwa komoya
Ukunisela imigwaqo yezimayini, ukusebenzisa izembozo zomthwalo, ukulungiswa kwezimoto, kanye nezindawo zokuvikela ukungcola kunganciphisa ukungcola kothuli.
4. Ukuhlinzekwa kwamanzi ahlanzekile kanye nokuhlanzeka
Uma imithombo yamanzi yezakhamuzi ithinteka, izinkampani kanye nohulumeni baphoqelekile ukuhlinzeka ngezinye izindlela zamanzi ahlanzekile eziqhubekayo, hhayi nje usizo lwesikhashana.
5. Ukuqapha impilo kanye nokufinyelela izinsizakalo zezokwelapha
Kudingeka kwenziwe izinhlelo zokuhlola njalo, okuhlanganisa ukuhlolwa kwezifo zokuphefumula, ukuhlolwa ikhwalithi yamanzi ekhaya, kanye nokuhlolwa kokuchayeka ensimbini esindayo uma kudingeka.
6. Imfundo yomphakathi kanye nokubandakanyeka kwezakhamuzi
Ukuhlanganyela komphakathi ekuqapheni imvelo kubalulekile ekwandiseni ukuzibophezela. Izakhamuzi zidinga ulwazi oluqondakala kalula mayelana nezingozi kanye nezinyathelo zokuvimbela.
7. Ukubuyiselwa kwemisebenzi ngemva kokumba
Ukubuyiselwa komhlaba, ukuvuselelwa kwezitshalo, kanye nokuphathwa kwemigodi yangaphambili yezimayini kubalulekile ukuvimbela izikhukhula eziyingozi, ukudilika komhlaba, kanye nokungcola okuqhubekayo.
Isiphetho
Imisebenzi yezimayini ingaletha izinzuzo zomnotho, kodwa futhi inamandla okubangela imiphumela ebanzi yezempilo emiphakathini ezungezile, kusukela ezinkingeni zokuphefumula nezifo ezibangelwa ukungcola kwamanzi kanye nokuchayeka ezintweni ezisindayo kuya ezinkingeni zempilo yengqondo nezenhlalo. Le miphumela ivame ukuzwakala kakhulu ngamaqembu asengozini njengezingane, abesifazane abakhulelwe, asebekhulile, nabampofu.
