Iziselo ezibandayo ziye zaba yeyona nto iphambili ekusetyenzisweni kwabantu imihla ngemihla.Nangona kunjalo, ngenxa yotshintsho lwengqiqo yokusetyenziswa kwabantu ngokubhekiselele kwimpilo nokhuseleko kunye nemigangatho engqongqo yolawulo lweshishini leziselo eziphunyeziweyo ngurhulumente, uhlengahlengiso lwemveliso kunye nokuphuculwa kwezixhobo zokusebenza kusemnyango.Izisombululo ze-Dongguan Kinda zokuhluza kunye neemveliso zigubungela umgangatho ofunekayo wokuhluza kunye nokwahlula iziselo ezithambileyo ukunceda abathengi baqinisekise ukuthotyelwa kwemveliso, ubuhle bezondlo kunye nokugcina incasa eyodwa.
Ezona mathiriyeli ziphambili zeziselo ezithambileyo ngamanzi okusela, iingcambu zeengcambu, iziqu, amagqabi, iintyatyambo kunye neziqhamo zezityalo, ulwelo oluxutyiweyo, izongezo zokutya ezibandakanya izimuncumuncu, izinto ezimuncu, iziqholo, iziqholo, iziqinisekiso zemibala yokutya kunye nezigcinakaliso, kwaye ezinye zongeza ezithile. iigesi (nitrogen, carbon dioxide, etc) ukutyebisa incasa kunye namava imveliso.Kwinkqubo yokuvelisa, i-sterlization, i-particle kunye ne-interception yokungcola, ukucaciswa ngokuchanekileyo, njl.
