This research identified quantified and scaled toxic metals and compounds in residual ash after burning electronic waste (e-Waste). Research used cell phone components divided into four categories: batteries, screens, circuit boards and plastics. Results of identified toxicants were then applied to the US EPA's chemical life-cycle assessment model 'tools for the reduction and assessment of chemical and other environmental impacts' (TRACI). TRACI analysis assisted in scaling identified toxicants into order of potential impact on ecotoxicity, and human health (cancerous and non-cancerous). Applying TRACI's model to results, allowed for designation of which sources of exposure offer greater impact among urban air, rural air, freshwater, sea water, agricultural soil, and natural soil for specific metals and compounds. Antimony, arsenic, barium, beryllium, cadmium, chromium, copper, lead, mercury, molybdenum, nickel, silver, thallium, vanadium, zinc, benzene, chloroform, TCDD, and TCDF were identified, quantified and scaled for ecotoxicity, cancerous and non-cancerous potential impacts.
