Phytotoxicity Assessment of Ashes Generated From Household Combustion of Conventional Fuels, Mixed Fuels, and Municipal Waste

Land Degradation &Development, EarlyView.
ABSTRACT The main aim of the study was to assess the toxicity of ash generated in household furnaces through the combustion of materials most commonly burned in individual households. The toxicity tests were conducted using plant bioassays with cress (Lepidium sativum), mustard (Sinapis) and sorghum (Sorghum) seeds.
