Ffenna twagala nnyo langi ennungi, si bwe kiri? Kiba kya kitalo nga langi ennungi eyongezeddwa ku bisenge by’awaka waffe, engoye ze twambala n’ebintu bye tukozesa. Naye teebereza, watya singa ddala langi ennungi gy’oyagala okukozesa efuuka obutwa obutta? Leero ngenda kwogera naawe ku mboozi ewunyiriza, entuufu. Eno mboozi ekwata ku langi ya kiragala omutangaavu eyali ewamba Bungereza yonna, naye mu kiseera kye kimu n’etta abantu mu kasirise.
Langi eyo eya kiragala etta eyali buli wamu
Emboozi eno etandikira mu Bungereza mu kyasa eky’ekkumi n’omwenda. Mu kiseera ekyo, olw’enkyukakyuka mu by’amakolero, amakolero buli wamu, n’eggulu nga lijjudde omukka, abantu baali baagala nnyo langi ya kiragala ey’obutonde. Mu kiseera ekyo, langi esikiriza ennyo, eya kiragala omutangaavu yajja mu maaso. Yali eyitibwa ‘Scheele’s Green’. Langi eno yatuumibwa erinnya ly’omukugu mu by’eddagala Omusweden eyagizuula mu 1778. Langi eno yafuuka ya ttutumu nnyo ne kiba nti yakozesebwa ku buli kimu okuva ku bbugwe w’olubiri lwa Buckingham okutuuka ku bibikka ebitabo, engoye, eby’okuzannyisa, eby’okuyooyoota keeki, ne ssweeta. Yali langi ya "it" mu kiseera ekyo, kwe kugamba, langi esinga okwettanirwa.
Naye emabega w’obulungi buno mwalimu ekyama ekitta. Langi eno yakolebwa nga batabula ekikomo ne okisigyeni n'ekirungo eky'obutwa ennyo ekiyitibwa arsenic .
Mu ngeri ennyangu, abantu mu kiseera ekyo baali basiiga obutwa buno obutta mu maka gaabwe ne mu mibiri gyabwe mu butamanya.
Ddala arsenic kye ki?
Arsenic elementi esobola okusangibwa mu butonde mu nsi yaffe ne mu mazzi agali wansi w’ettaka. Mu kiseera ekyo, abasawo era baakozesanga arsenic mu bungi obutono okujjanjaba endwadde ng’omusujja, asima,
n’enkwaso . Ekyewuunyisa, ne leero, ekirungo ekiyitibwa arsenic trioxide kikozesebwa bulungi ng’eddagala eriweweeza ku bulwadde bw’omusaayi okujjanjaba ekika kya leukemia eky’amaanyi ennyo, Acute Promyelocytic Leukemia. Naye mu kiseera kye kimu, abantu bamaze ebyasa bingi nga bakimanyi nti arsenic butwa bwa ntiisa. Mu byafaayo, era kyayitibwanga "kabaka w'obutwa" kubanga kyakozesebwanga okutta abalabe ba bakabaka mu nkukutu. Olw’okuba tegulina kawoowo wadde obuwoomi, kyangu okugutabula mu mmere n’ebyokunywa. Ate era, olw’okuba obubonero obusooka obw’obutwa bwa arsenic, gamba
ng’okuziyira ,
okusiiyibwa , n’okuzimba
olubuto , bwe bufaananako n’obubonero bw’endwadde nga kkolera, ezaali zitera okulabika mu kiseera ekyo, tewali yali ateebereza nti butemu.
Akabenje kazuuse
Nga mu 1839, omukugu mu by’eddagala Omugirimaani yalabula ku nsonga eno. Yagambye nti singa Scheele’s Green ewanirirwa mu bisenge ebinyogovu, eyinza okufulumya omukka ogw’obutwa. Nga wayise ekiseera kitono nga lipoota eyo efulumiziddwa, abaana bana mu London baafa olw’okulemererwa okussa. Ebisenge byabwe byali byakawanikibwako wallpaper eno eya kiragala. Oluvannyuma wallpaper eno bwe yakeberebwa, kyazuulibwa nti buli square foot yalimu ekirungo kya arsenic ekitta. Okufa n’endwadde endala nazo zaava ku langi eno eya kiragala. Omusawo omu yazuula ekirungo kya arsenic mu bisenge bino bwe yanoonyereza ku nsonga nti buli kiro yava mu kisenge kye ekyalimu bbugwe wa kiragala ng’olubuto lumuluma, ng’aziyira, era ng’ayagala nnyo okusesema. Yagambye nti, "Abantu bangi mu Bungereza bagenda baweebwa obutwa mpola."
Kiki ekibaawo nga arsenic ayingidde mu mubiri?
Obulabe arsenic bw’akola ku mubiri okusinga businziira ku bungi (dose) gy’amira. Ka tulabe ebivaamu.
| Obutonde bw’obutwa | Obubonero n’ebivaamu |
|---|
| Acute Poisoning ( okumira obungi omulundi gumu) . | - Ekisooka, obuzibu mu nkola y’okugaaya emmere (okuziyira, okusiiyibwa, obulumi obw’amaanyi mu lubuto , ekiddukano ) bubaawo.
- Puleesa ekka mangu.
- Obutabeera bulungi mu nnyimba z’omutima (arrhythmias) bubaawo.
- Okufiirwa amazzi amangi okuva mu mubiri kiyinza okuvaako okuwuniikirira, okugwa kw’emisuwa gy’omutima , n’okufa n’okufa mu ssaawa ntono.
- Singa obulamu buwona, omuwendo gw’obutoffaali obweru n’obumyufu gujja kukendeera nnyo mu nnaku ntono. Kino olwo kiyinza okuvaako obulwadde bw’obusimu obuyitibwa peripheral neuropathy mu ngalo n’ebigere, ekivaako okuzimba, okuzirika, n’okukkakkana ng’afa.

| Obutwa obutawona (okumira okumala ebbanga eddene) . | - Kyongera obulabe bwa kookolo w’olususu, kookolo w’amawuggwe ne kookolo w’ekibumba. Era kiyinza okuvaako kookolo w’ekibumba n’ensigo.
- Kireeta ebizibu bingi ebitali bya kookolo. Kikwatagana ne puleesa, ssukaali n’obulwadde bw’emisuwa gy’obwongo.
- Obujulizi obupya bulaga nti kiyinza okukosa obubi obulamu bw’okuzaala n’okukosa enkula y’abaana ey’obusimu.

Mu kiseera ekyo, abantu baali tebategeera bulungi bikolwa bya arsenic okumala ebbanga eddene. Naye baalaba ebimu ku byo. Baatuuka n’okukiraga mu bitabo by’ebyobujjanjabi ne katuni mu mpapula z’amawulire, gamba ng’okufuuka langi esukkiridde n’okukendeera olw’okussa oba okumira arsenic.
Enkomerero ya langi n’essomo gye tuli
Wadde nga waliwo okulabula kuno, green wallpaper yali bizinensi nnene mu kiseera ekyo. Ne William Morris, omukubi w’ebifaananyi omututumufu, yakozesa langi eyo. Teyakoma awo, era yali nnannyini migabo mu kkampuni ya arsenic esinga obunene mu kiseera ekyo. Yasekeredde okutya kwa arsenic ng’agamba nti, “Kifaananako okutya abasamize.” Kyokka mu 1879, omugenyi ow’obwakabaka mu Lubiri lw’e Buckingham yalwala oluvannyuma lw’okusula mu kisenge ekyali ku bbugwe eya kiragala. Oluvannyuma lw’ekintu kino, Kkwiini Victoria yalagira
ebipande byonna ebya kiragala mu lubiri luno biggyibwewo . Mpola mpola, okumanyisa abantu kwasaasaana nga bayita mu lipoota z’amawulire. Gavumenti nga tennassaawo mateeka, abantu bennyini baatandika okugaana ebintu ebirimu ekirungo kya arsenic. Kino kyawaliriza abakola langi okukola langi ezisingako obukuumi.
Ekisinga obukulu kye tutegeera okuva mu mboozi eno kiri nti si kirungi okulimbibwa obulungi obw’ebweru obw’ekintu. Era kiraga engeri okumanyisa abantu gye kulina amaanyi bwe kituuka ku bulamu bw’abantu.
Ne leero, kizibu okuddamu okutonda langi ya kiragala ey’obutonde. N’ezimu ku langi za kiragala ezikozesebwa ennaku zino tezitta nnyo butonde. Okugezaako kw’abantu okukoppa obutonde kukyali kwa kabi.
Obubaka Obutwala Awaka
- Oluusi wayinza okubaawo obulabe obukwekebwa emabega w’ebintu ebirabika ng’ebirabika obulungi, n’olwekyo weegendereze naddala ku bintu ebirimu eddagala.
- Arsenic butwa butta abantu nga buyinza okutta omuntu singa omira mu bungi omulundi gumu, era buyinza okuvaako kookolo n’endwadde endala ez’amaanyi singa omira mpola.
- Bw’oba ggwe oba omuntu gw’omanyi ateebereza obutwa obw’engeri yonna, laba omusawo mu bwangu oba tuukirira ekitongole kya National Poisons Information Center mu ddwaaliro lya Colombo National Hospital.Kuba ku ssimu ya National Poisons Information Centre.
- Okumanyisa abantu ku by’obulamu kuyinza okuba okw’amaanyi nga, oba n’okusinga, amateeka n’ebiragiro bya gavumenti.
