Bepa risina carbonrinoshandiswa sezvinyorwa zvebhizimisi zvinoda kopi imwe kana akawanda epakutanga, akadai semarisiti uye marisiti.Makopi acho aiwanzova mapepa ane mavara akasiyana.
Vanhu vazhinji vanofunga kudarocarbonless copy paperzvichakanganisa hutano hwevanhu.PCB(polychlorinated biphenyl) mubepa risina kabhoni zvakarambidzwa kuma1970 nekuda kwehutano.Ongororo inoratidza kutipepa risina carboninogadzirwa mushure me2000 haizokonzeri maitiro akashata kumuviri wemunhu.Nekuda kwekukurumidza kukura kweindasitiri, bepa risina kabhoni rinogadzirwa rinowedzera kushamwaridzana uye rine hutano.
Kazhinji, bepa risina kabhoni remhando yakashata rine BPA, BPA inogona kukanganisa hutano hwako. Ikozvino, bepa remhando yepamusoro kabhoni ndere BPA mahara. Nekuwedzera kuri kuita kuwanikwa kwemainkjet nemaprinta asingadhure, kushandiswa kwemhando dzakasiyana siyana kwadzikira. mabhizinesi nekuti zviri nyore kugadzira makopi ezvinyorwa.
Fekitari yeduane makore akawanda eruzivo mukugadzira mapepa asina kabhoni.Uye bepa risina kabhoni harina BPA nePCB.Fekitari yedu inogara ichitevedzera kuchengetedza kwezvakatipoteredza uye hutano.
