Amsar ita ce a'a, ƙananan hayaƙin sifilin halogen na USB ba ya dace da muhalli.Dalilan su ne:
(1) abin da ake kira kebul na haɗin gwiwar muhalli, yana nufin rashin gubar, cadmium, chromium hexavalent, mercury da sauran ƙarfe masu nauyi, ba ya ƙunshi ɓarnawar wuta ta SGS waɗanda aka gane ƙungiyoyin gwaji akan gwajin aikin muhalli, daidai da EU.

(2) low-shan hayaki halogen-free na USB kube da aka yi da ƙananan hayaki lokacin da mai tsanani, kuma kanta ba ya ƙunshi halogen thermoplastic ko thermosetting abun da ke ciki, inda halogen darajar ≤ 50PPM, hydrogen halide abun ciki a cikin konewa na gas <100PPM, bayan Kona iskar hydrogen halide wanda aka narkar da shi a cikin ruwa PH darajar 24.3 (rauni acidity), samfurin yana ƙone a cikin rufaffiyar akwati ta hanyar hasken haskensa na 260%.

A takaice dai, abin da ke sama shine ko ƙananan hayaki maras halogen na USB yana da alaƙa da abun ciki na USB.Daga abin da ke sama za mu iya sanin cewa akwai alaƙa da yawa da bambance-bambance tsakanin ƙananan igiyoyi marasa amfani da hayaƙin halogen da igiyoyi masu dacewa da muhalli.Low hayaki mara halogen na USB ba lallai ba ne waya da kebul na abokantaka na muhalli, amma waya da kebul ɗin da ba ta dace da muhalli ba dole ne ta zama ƙaramin hayaƙi mara kebul na halogen.Domin inganta amincin da'ira a gida, Sunua Advanced Material yana ba da shawarar yin amfani da ƙananan hayaki da kebul na hana harshen wuta mara halogen azaman wayar lantarki ta gida.
