摘要：Abstract Environmental effects of open wastes disposal continue to receive global attention. This study determined the heavy metals pollution status of pasture grass around Katima Mulilo municipal solid wastes dumpsite, Namibia. Samples of the pasture grass were collected from grassland around the wastes dumpsite and a control site and then analyzed for levels of the heavy metals: Pb, Cr, Cd, As, Ni, Co, Cu and Mn using standard analytical procedures. The results obtained revealed that Mn recorded the highest mean concentration of 102.50mg/kg while Co recorded the lowest level (0.13mg/kg). Generally, the present levels of the heavy metals were below their health regulatory limits. However, the degree of contamination of the pasture grass was significantly higher (paired sample mean t-test, p .
