Tasirin muhalli na nanoparticles na azurfa

A cikin shekara ta 2015, an sayar da bututun hakora miliyan 251 a Amurka. Wani bututu guda yana riƙe da kusan 170 grams na maganin hakora, don haka kimanin 43 kilotonnes na maganin hakori ana wanke su cikin tsarin ruwa a kowace shekara. Toothpaste ya ƙunshi Nanoparticles na azurfa, wanda aka fi sani da nanosilver ko AgNPs, a tsakanin sauran mahadi.

Kowane bututun maganin hakora ya ƙunshi kusan 91 MG na nanoparticles na azurfa, tare da kusan tan 3.9 na nanoparticle na azurfur da ke shiga cikin muhalli a kowace shekara. Nanoparticles na azurfa ba a share su gaba ɗaya daga ruwa ba yayin tsarin kula da ruwa mai guba, mai yiwuwa yana haifar da mummunar tasirin muhalli.

Nanoparticles na azurfa suna da halaye daban-daban na physicochemical daga ion na azurfar kyauta, Ag + kuma suna da ƙarin kayan gani, electromagnetic, da catalytic. Kwayoyin da ke da girman 100 nm ko ƙasa da haka na iya samar da nau'in iskar oxygen. Ƙananan barbashi ƙasa da 10 nm na iya wucewa ta cikin membranes na salula kuma su tara a cikin tantanin halitta. An kuma gano nanoparticles na azurfa don haɗewa da membranes na salula, a ƙarshe ya watsar da ƙarfin motsi na proton, wanda ke haifar da mutuwar sel

Nanoparticles na azurfa waɗanda suka fi girma fiye da buɗewar furotin na tashar membrane na iya sauƙaƙa tashoshi, wanda ke haifar da rushewar membrane permeability da sufuri. Koyaya, an nuna tasirin antimicrobial na nanoparticles na azurfa don raguwa lokacin da aka narke a cikin kafofin watsa labarai na ruwa.

Ion na azurfa kyauta na iya zama mai guba ga ƙwayoyin cuta da nau'in planktonic a cikin ruwa.  Ion azurfar da aka caje da kyau kuma na iya haɗawa da ganuwar ƙwayoyin ƙwayoyin cuta da ba ta dace ba, wanda ke haifar da kashe enzymes na salula, rushewar ƙwayar cuta, kuma a ƙarshe, sel lysis da mutuwa.  Duk da haka, ba a lura da gubarsa ga ƙananan ƙwayoyin cuta ba tun lokacin da ion azurfa kyauta yana samuwa a cikin ƙananan ƙididdiga a cikin tsarin kula da ruwa da kuma yanayin yanayi saboda kamanninsa tare da ligands irin su chloride, sulfide, da thiosulfate .
