Kungenzeka ukuthi uke wezwa ngama-red tide, kepha ngabe uyawazi umthelela wabo kubantu nasemvelweni?

Amagagasi abomvu angaba nomthelela osabalele empilweni yasolwandle, futhi angakuthinta uma ubhukuda emanzini noma udla ukudla kwasolwandle okungcolile.

Ake sibheke ukuthi yini ebangela i-red tide, ukuthi iyithinta kanjani imvelo, nokuthi yini ongayenza ukuze unciphise ukuvezwa kwakho ubuthi bayo.

Yini ebangela i-red tide?

I-red tide kwesinye isikhathi ibizwa ngokuthi yi-algae bloom eyingozi (i-HAB). Yenziwe ulwelwe oluncane noma i-phytoplankton, ebalulekile empilweni yasolwandle.

Lapho laba balwelwe bethola izakhamzimba ezedlulele, bangaphindaphindeka ngokungalawuleki, babe isisindo esikhulu esiklinya impilo yasolwandle eseduze. Ezinye izinhlobo ze-algae, njenge UKarenia brevis, inganikeza ulwandle umbala obomvu, yingakho igama, i-red tide.

Nokho, akuwona wonke amagagasi abomvu afaka umbala olwandle. Kwezinye izimo, ama-HAB awanele ngokwanele ukunikeza ulwandle i-hue ethile. Umphumela wazo ogqame kakhulu uvame ukubonakala ku-ecosystem ezungezile.

Ubuthi be-HAB buyingozi ezilwaneni ezincelisayo zasolwandle, izinyoni nezimfudu ezihlala emanzini. Zingaba nethonya nasezilwaneni zasendle ezondla izilwane ezivezwa yi-red tide.

Ingabe i-red tide iyingozi kubantu?

Izinhlobo eziningi ze-phytoplankton azilimazi kubantu, kepha inani elincane lezinhlobo laziwa ngokukhiqiza ama-neurotoxin anamandla. Lawa ma-toxin angadluliselwa ezansi kochungechunge lokudla, athinte abantu ababafaka ngengozi.

Ukusetshenziswa kwe-shellfish, njengezimbaza noma izimbaza, kungenye yezindlela ezivame kakhulu ukuthi abantu bathintwe yi-red tide.

Ziyini izimpawu zobuthi begazi elibomvu?

Ukufaka ukudla kwasolwandle okunobuthi

I-Paralytic shellfish poisoning (PSP) yisifo abantu abangasithuthukisa uma bedla ukudla kwasolwandle okungcoliswe umoya obomvu.

I-PSP ingasongela impilo futhi ivame ukuzibonakalisa kungakapheli amahora amabili wokudla. Izimpawu zifaka:

• ukuncinza
• evuthayo
• ukuba ndikindiki
• ukozela
• ukukhubazeka kokuphefumula

Ezimweni ezingabulali, lezi zimo zingavela ngokuhamba kwezinsuku ezimbalwa. Ezimweni ezinzima, abantu bangathola ukuboshwa kokuphefumula kungakapheli amahora angama-24 ukusetshenziswa.

Amanye ama-syndromes anobuthi be-shellfish afaka:

• I-Amnesic shellfish poisoning (ASP). Izimpawu ze-ASP zifaka phakathi isicanucanu, ukuhlanza, nohudo. Uma ishiywe ingalashwa, ingaholela ekulimaleni unomphela kohlelo lwemizwa oluphakathi.
• Uhudo lwe-shellfish poisoning (DSP). I-DSP ingadala isicanucanu, ukuhlanza, kanye nezilonda zesisu, futhi abantu bathambekele ekubeni baphelelwe amanzi emzimbeni ngokweqile.
• Ubuthi be-Neurotoxic shellfish (NSP). I-NSP ingadala ukuhlanza, isicanucanu, nezinye izimpawu zezinzwa.

Ukuhlangana namanzi anobuthi

Ukuthintana ngokomzimba ne-red tide kungaholela ezinkingeni zokuphefumula, ngisho nakubantu abangenazo izinkinga zokuphefumula zangaphambilini.

Ukusabela kumathambo abomvu kungaba kubi kakhulu kubantu abane-asthma, emphysema, noma esinye isifo samaphaphu esingapheliyo.

Ubuthi obuhambisana ne-red tide bungadala ukucasuka kwesikhumba, ukuqubuka, namehlo avuthayo noma abuhlungu.

Ubuthi be-red tide ezinjeni

Izinja, ikakhulukazi, zingahle zithambekele emiphumeleni emibi emibi ye-red tide uma ihlangana namanzi angcolile. Kwezinye izimo, ubuthi be-red tide bungadala izimpawu zezinzwa ezinjeni.

Funa ukunakekelwa kwezilwane ngokushesha uma isilwane sakho:

• isebenza ngokuhlukile
• uhlangabezana nokuquleka
• kuyaxaka
• uyaqhaqhazela noma ulahlekelwe ibhalansi
• unesifo sohudo

Ngabe i-red tide iphathwa kanjani kubantu?

Ayikho ikhambi elaziwayo lezimo ezibangelwa i-red tide, njenge-PSP. Izimo ezinzima zingaphathwa ngokusetshenziswa kwezinhlelo zokusekela impilo, njenge-mechanical respirator kanye ne-oxygen kuze kube yilapho ubuthi budlula ngokuphelele ohlelweni lwakho.

Ungakuvimbela kanjani ukuthi ubuthi begagasi elibomvu

Kunezindlela ezimbalwa zokuvimbela ukuthi ubuthi bama-red tide bungavinjelwa:

• Gwema ukungena emizimbeni yamanzi anephunga elibi elehlukile, avele agqamile, noma anogwebu, isikhunta, noma amacansi e-algal (ukunqwabelana okufana noshidi kwe-algae eluhlaza okwesibhakabhaka) ebusweni.
• Landela ukuholwa kwendawo noma kombuso mayelana nokuphepha kwamanzi.
• Bheka amawebhusayithi ezemvelo noma wombuso ngamabhishi endawo noma ukuvalwa kwechibi ngaphambi kokuvakashela.
• Ungaphuzi ngqo emachibini, emifuleni, noma emachibini.
• Musa ukudoba, ukubhukuda, isikebhe, noma ukubamba iqhaza kwezemidlalo yamanzi ezindaweni ezihlangabezana nomsinga obomvu.
• Hlanza izilwane ezifuywayo ngamanzi ahlanzekile ngemuva kokungena echibini, echibini, noma olwandle. Ungabavumeli ukuthi bakhothe uboya babo baze bagezwe.
• Landela ukuholwa kwendawo lapho usebenzisa inhlanzi noma i-shellfish evuniwe.
• Gwema ukudla izinhlanzi ezinkulu zamakhorali.

Ama-shellfish athengwe ezitolo nasezitolo zokudlela ngokuvamile aphephile ukuthi angadliwa ngesikhathi sokuhamba okubomvu ngoba imboni ye-shellfish ibhekwe kakhulu yizikhungo zombuso zokuphepha kwe-shellfish.

Ama-shellfish atholakala ezentengisweni kaningi awavunwa endaweni futhi, uma evunwa endaweni, ahlolwe ubuthi ngaphambi kokuthengiselwa umphakathi.

Iningi labantu liyakwazi ukubhukuda ngesikhathi segagasi elibomvu ngaphandle kwezingozi ezinkulu, kepha kungadala izimpawu ezinjengokucasuka kwesikhumba nokuzwa okushisayo emehlweni.

Ukuthatha ukhiye

I-red tide kungenzeka ingabi yingozi kubantu abangavezwa ubuthi bayo, kodwa ingaba nomthelela omubi empilweni yasolwandle.

Uma udla ukudla kwasolwandle okungcoliswe ubuthi, izimpawu zemizwa kungenzeka futhi zibe zimbi. Ayikho i-antidote yama-syndromes afana ne-PSP, kepha izinhlelo zokusekela impilo, njenge-mechanical respirator kanye ne-oxygen, zingakusiza wenze ukululama okugcwele.

Bheka udokotela uma ucabanga ukuthi kungenzeka ukuthi udle izinhlanzi zasolwandle ezingcolile.

Ungazigwema lezi zinhlobo zama-syndromes nokucasuka ngokomzimba kusuka kugagasi elibomvu ngokuthatha izinyathelo zokuqapha ngaphambi kokuya echibini, echibini noma olwandle.
