Ukungcola kwe-mercury kubi impela, ikakhulukazi uma le nsimbi esindayo itholakala ekugxileni okukhulu emzimbeni. IMercury inganqwabelana emzimbeni futhi ithinte izitho eziningana, ikakhulukazi izinso, isibindi, uhlelo lokugaya ukudla nohlelo lwezinzwa, okuphazamisa ukusebenza komzimba nokudinga ukuqashwa kwezempilo impilo yonke.

Ubuthi obubangelwa i-mercury buthule futhi kungathatha izinyanga noma iminyaka ukuzibonakalisa ngezibonakaliso ezinjenge:

• Ubuthakathaka, ukukhathala njalo;
• Ukwehla kwesifiso sokudla nokulahlekelwa isisindo okulandelayo;
• Isilonda esiswini noma i-duodenum;
• Ukuguqulwa kokusebenza kwezinso;
• Amazinyo abuthakathaka futhi aqhekekile, anokuthambekela kokuwa;
• Ukucasula nokuvuvukala kwesikhumba lapho kuthintana ngqo ne-mercury.

Lapho inani elikhulu le-mercury linqwabelana ohlelweni lwezinzwa, i-neurotoxicity ibonakala, engabonakala ngezinye izimpawu nezimpawu, okuyizona eziyinhloko:

• Ukushintsha okungazelelwe nokuvamile kwemizwa;
• Ukwesaba, ukukhathazeka nokucasula;
• Izinkinga zokulala, njengokuqwasha kanye namaphupho amabi kaningi;
• Izinkinga zememori;
• Ikhanda kanye ne-migraine;
• Isiyezi kanye ne-labyrinthitis;
• Ukudukelana kanye nemibono.

Zonke lezi zinguquko zingenzeka uma kunokuchayeka kokugxila okuphezulu kwe-mercury, okungaphezu kwama-micrograms angama-20 ngemitha ngayinye, engatholwa ngokuhamba kwesikhathi ngesikhathi somsebenzi noma ngokudla.

IMethylmercury uhlobo lwe-mercury olungaholela ekudakweni kalula kubantu, ngoba lwenziwa ngamagciwane akhona endaweni yasemanzini, aqoqelwa ezilwaneni ezikhona emanzini, ikakhulukazi izinhlanzi. Ngakho-ke, ukungcoliswa kwenzeka ngokungeniswa kwezinhlanzi ezingcoliswe yi-mercury. Ukungcola nge-methylmercury kubi kakhulu ngesikhathi sokukhulelwa ngoba le nsimbi ingathinta ukukhula kwengqondo yomntwana nezinye izinguquko ezihlala njalo, noma ngabe kungcoliswa ukwelashwa.

Ukungcola kungenzeka kanjani

Ukungcoliswa yi-mercury noma i-methylmercury kungenzeka ngezindlela ezintathu eziyinhloko:

1. Umsebenzi wobungcweti, kunengozi enkulu yokungcola kubantu abasebenza ezimbonini zezimayini, ezimayini zegolide noma ezimbonini ze-chlor-sora, lapho kwenziwa amalambu we-fluorescent, ama-thermometer, udayi namabhethri, ngoba kulula ukuvezwa kwi-mercury. Ukungcola nge-mercury ngenxa yomsebenzi wobungcweti kuvame ukwenzeka ngokuhogela, ngokuqongelela le nsimbi emaphashini nokuholela ezinkingeni zokuphefumula;
2. Ngokusebenzisa ukwelashwa kwamazinyo, yize kungavamile kakhulu futhi kungavamile ukuholela ezinkingeni ezinkulu zempilo, kunengozi yokungcola kwe-mercury. Lolu hlobo lokungcola luthinta ngqo igazi, lubangele ukulimala ohlelweni lokugaya ukudla kanye nokulimala unomphela kwezinzwa;
3. Ngokusebenzisa imvelo, ngokusebenzisa amanzi noma inhlanzi engcolisiwe. Lolu hlobo lokungcola luvame kakhulu ezindaweni ezisemfuleni, njengoba kwenzeka e-Amazon, ezindaweni zezimayini zegolide nasezindaweni ezisetshenziswa kakhulu i-mercury, kodwa futhi kungathinta noma ngubani odla amanzi noma ukudla okungcoliswe yile nsimbi, uma kwenzeka izingozi zemvelo.

Inhlanzi equkethe i-mercury

Ezinye izinhlanzi zamanzi ahlanzekile namanzi anosawoti ziyimithombo yemvelo ye-mercury, kepha lezi zinamanani amancane ngokuvamile angenabungozi empilweni. Izinhlanzi ezinengcuphe ephansi yokungcoliswa yile nsimbi yilezi:

• Tambaqui, jatuarana, pirapitinga kanye ne-pacu, ezondla imbewu nezithelo, ezingaqukatha i-mercury;
• IBodo, i-jaraqui, i-curimata ne-branquinha, ngoba zondla odakeni olukhona ezansi nemifula nezilwanyana ezincane ezibhekele ukuhlanganiswa kwe-methylmercury;
• I-Arowana, i-pirarara, i-yam, i-mandi, i-matrinchã ne-cuiu-cuiu, ezondla izinambuzane nama-plankton.
• Dourada, cub, piranha, peacock bass, surubim, hake nepende, ngoba zondla ezinye izinhlanzi ezincane, zithola inani elikhulu le-mercury.

Kodwa-ke, ezimweni zezingozi zemvelo, lapho kukhona ukungcoliswa nge-mercury esifundeni esithile, zonke izinhlanzi ezivela ezindaweni ezithintekile akufanele zidliwe ngoba zingaba nemithamo ephezulu ye-mercury enyameni yazo, engadala ubuthi kubantu.

Okufanele ukwenze uma usola ukuthi unegciwane

Uma kwenzeka kungcoliswa okusolwayo, kufanele kuboniswe ukwelashwa bese waziswa ngokusola kwakho, futhi udokotela kufanele ayalele ukuhlolwa ukuze kuhlolwe inani le-mercury egazini.

Ukungcola kungaqinisekiswa ukuhlolwa kwegazi okulinganisa inani leMercury egazini noma ngokulinganisa inani elisezinweleni. Ngokwe-World Health Organisation (WHO) isilinganiso esikhulu se-mercury ezinweleni kufanele sibe ngaphansi kuka-7 µg / g. Okunye ukuhlolwa kungadingeka futhi ukukala imiphumela yezempilo ye-mercury, njenge-MRI, i-electroencephalogram, ukuhlolwa kwamahomoni nokuhlolwa okuthile kwesitho ngasinye, kuya ngezicubu ezithintekile.

Ukwelashwa kokungcola kwe-mercury

Ukwelashwa kungenziwa ngokusetshenziswa kwezidakamizwa ezikhohlisayo ezenza kube lula ukuqeda i-mercury, okumele ikhonjiswe ngudokotela. Ngaphezu kwalokho, kungadingeka ukuthatha imithi yokulwa nokukhathazeka nokudangala, uma kwenzeka ngenxa yokungcola, kanye nokwengeza i-vitamin C, E ne-selenium. Ukuhambisana nodokotela wezengqondo noma udokotela wezifo zengqondo kungaba usizo olubalulekile ekuqedeni ukwelashwa, kuthuthukise izinga lomuntu lokuphila. Bona ukuthi ungakugwema kanjani ukungcoliswa kwe-mercury.
