Shuruudaha ilaalinta deegaanka ee baakadaha ayaa la hagaajiyay, iyo codsiga baakadaha waraaqaha ee meelo badan mustaqbalka waa mid aad iyo aad u ballaaran.
1. Warshada waraaqaha waa dib loo warshadayn karaa.
Warshadaha baakadaha waraaqaha ayaa loo arkaa inay tahay warshad waara sababta oo ah warqad dib loo warshadayn karo.
Maalmahan, baakadaha ayaa laga arki karaa meel kasta oo nolosheenna ah.Dhammaan noocyada alaabadu waa midabyo iyo qaabab kala duwan.Waxa ugu horreeya ee soo jiita indhaha macaamiisha waa baakadaha alaabta.Habka horumarinta ee warshadaha baakadaha oo dhan, baakadaha waraaqaha, sida alaabta baakadaha caadiga ah, ayaa si ballaaran loo isticmaalaa wax soo saarka iyo nolol maalmeedka.Iyadoo "xakamaynta balaastikada" si joogto ah loo baahan yahay, baakadaha waraaqaha ayaa la odhan karaa waa walxaha ugu badan ee deegaanka.
2.Waa maxay sababta aan ugu baahanahay isticmaalka baakadaha waraaqaha?
Warbixin uu soo saaray Bangiga Adduunka ayaa lagu sheegay in Shiinaha uu yahay dalka ugu badan ee soo saara qashinka.Sannadkii 2010, marka loo eego tirakoobka Ururka Fayadhowrka Deegaanka Magaalooyinka ee Shiinaha, Shiinuhu wuxuu soo saaraa ku dhawaad 1 bilyan oo qashin sanad walba, oo ay ku jiraan 400 milyan oo tan oo qashinka gudaha ah iyo 500 milyan oo tan oo qashinka dhismaha ah.
Hadda ku dhawaad dhammaan noocyada badda waxay leeyihiin wasakh caag ah oo jidhkooda ku jira.Xataa gudaha Mariana Trench, PCB-yada ceeriin kiimikaad ah ayaa laga helay (polychlorinated biphenyls).
Isticmaalka ballaaran ee PCB-yada ee warshadaha ayaa sababay dhibaatada deegaanka ee caalamiga ah. Polychlorinated biphenyls (PCBs) waa kansar, kuwaas oo si sahlan loogu ururin karo unugyada adipose, oo keena cudurrada maskaxda, maqaarka iyo visceral, oo saameeya habdhiska dareenka, taranka iyo difaaca.PCB-yada waxay sababi karaan in ka badan tobanaan cudur oo bini'aadmi ah, waxayna u gudbin karaan uurjiifka iyada oo loo marayo mandheerta hooyada ama nuujinta.Tobannaan sano ka dib, badi dhibbanayaasha ayaa weli leh sun aan la soo saari karin.
Qashinkan balaastikada ah ayaa dib ugu soo noqda silsiladda cuntada qaab aan la arki karin.Balaastiggani waxay inta badan ka kooban yihiin kansar iyo kiimikooyin kale, kuwaas oo ay fududahay in ay saameyn xun ku yeeshaan caafimaadka aadanaha.Marka laga soo tago in loo beddelo kiimiko, balaastiiggu waxay jidhkaaga u geli doonaan qaab kale oo waxay sii wadi doonaan inay khatar geliyaan caafimaadkaaga.
Baakadaha warqadda waxaa iska leh baakad "cagaaran".Waa deegaan oo dib loo warshadayn karo.Iyadoo fiiro gaar ah loo leeyahay ilaalinta deegaanka, sanduuqyada kartoonada ayaa aad u doorbidi doona macaamiisha.
