Kunyange zvazvo maPCB ane mativi matanhatu achidhura zvakanyanya pane mamwe maPCB ane mativi maviri uye mana, mari iyi inopa pundutso inooneka kuburikidza nekuvimbika kwakawedzerwa, kunaka kwemasaini, kuomarara kwemasisitimu, uye hukuru hushoma hwemabhodhi nekuda kwekuwedzera kwehuwandu hwemarongero.
Takagadzirira kutanga?
udza mashoko Wonderful PCB nhasi kuti muwane mutengo, ongororo yeDFM, kana kubvunzana nehunyanzvi. Isa mafaira enyu ekugadzira kuhurongwa hwedu hwepamhepo kuti muwane mitengo ipapo ipapo kana kuti taurai nechikwata chedu cheinjiniya kuti mukurukure zvamunoda.
