Shaandheeye qiime jaban oo hawada wasakhowga ka nadiifiya qaybo yaryar

Arinta wasakhowga deegaanku waxay noqotay arin aad looga hadal hayo aduunka maanta.Wasakhowga deegaanka, oo ay badanaa keenaan kiimikooyinka sunta ah, waxaa ka mid ah hawada, biyaha, iyo wasakhowga ciidda.Wasakhowgani ma keeno oo kaliya burburinta noolaha, laakiin sidoo kale hoos u dhaca caafimaadka aadanaha.Heerarka wasakhaysan ee maalinba maalinta ka dambaysa sii kordhaya waxay u baahan yihiin horumar ka wanaagsan ama daahfurka tignoolajiyada isla markiiba.Nanotechnology waxay bixisaa faa'iidooyin badan si loo hagaajiyo tignoolajiyada deegaanka ee jira oo loo abuuro tignoolajiyad cusub oo ka wanaagsan tignoolajiyada hadda jirta.Dareenkan, nanotechnology waxay leedahay saddex awoodood oo waaweyn oo lagu dabaqi karo dhinacyada deegaanka, oo ay ku jiraan nadiifinta (dib u hagaajinta) iyo nadiifinta, ogaanshaha wasakhowga (dareemada iyo ogaanshaha), iyo ka hortagga wasakhowga.

Dunida maanta ee warshadaha la casriyeeyay, horumarna laga sameeyay, deegaankeena waxaa ka buuxa noocyo kala duwan oo wasakh ah oo ka soo baxa hawlaha bani'aadamka ama hababka warshadaha.Tusaalooyinka wasakhooyinkan waxaa ka mid ah carbon monoxide (CO), chlorofluorocarbons (CFCs), biraha culus (arsenic, chromium, lead, cadmium, mercury iyo zinc), hydrocarbons, nitrogen oxides, xeryahooda organic ( xeryahooda organic kacsan iyo dioxins), sulfur dioxide iyo qaybiya.Dhaqdhaqaaqyada bini'aadamka, sida saliidda, dhuxusha iyo gubashada gaaska, waxay leeyihiin awood weyn oo ay ku beddelaan qiiqa ka imanaya ilaha dabiiciga ah.Wasakhowga hawada ka sokow, waxa kale oo jira wasakhowga biyaha oo ay sababaan arrimo kala duwan, oo ay ka mid yihiin qashin-qubka, daadinta saliidda, daadinta bacriminta, dhirta iyo sunta cayayaanka, waxyaabaha ka soo baxa hababka warshadaha iyo gubashada iyo soo saarista shidaalka fosil.

Wasakhowga waxaa inta badan laga helaa isku qasan hawada, biyaha iyo ciidda.Haddaba, waxaan u baahanahay tignoolajiyad awood u leh in ay la socoto, ogaato oo, haddii ay suurtagal tahay, ka nadiifiso wasakhda hawada, biyaha iyo ciidda.Xaaladdan oo kale, nanotechnology waxay bixisaa awoodo iyo teknoolojiyad ballaaran si loo horumariyo tayada deegaanka jira.

Nanotechnology waxay bixisaa awoodda lagu xakameynayo walxaha nanoscale iyo abuurista alaab leh sifooyin gaar ah oo leh shaqo gaar ah.Sahannada laga soo xulay warbaahinta Midowga Yurub (EU) ayaa muujinaya rajo aad u sarreeya marka loo eego fursadaha/ saamiga khatarta ah ee la xidhiidha nanotechnology, halkaas oo intooda badan loo nisbeeyay rajada horumarinta tayada nolosha iyo caafimaadka.

Jaantus 1. Natiijada sahanka dadka ee Midowga Yurub (EU): (a) isu dheelli tirka fursadaha garashada iyo khatarta nanotechnology-ga iyo (b) khataraha mala awaalka ah ee horumarinta nanotechnology.
