ANALISIS KONSENTRASI TIMBAL PADA TANAMAN KUBIS (Brassica oleraceae L) DI KOTA TOMOHON

Abstract

ABSTRACT This study aims to determine the concentration of lead in cabbge plants in Tomohon city.  The results of this study are expected  to provide information to the  public about the amount of lead metal content in cabbage vegetables in Tomohon city. This research was conducted for 3 (three) months, from June to September 2018, the location of sampling in Tomohon City and then analyzed at the Baristand Laboratory.
