| Use of compost manure for lawn gardens has become increasingly attractive since it is inexpensive and has the added advantage of recycling a large waste. Compost is however believed to contain heavy metals such as lead, cadmium, and chromium among others, emanating from their use in various manufacturing industries and household commodities. Depending on the origin of the compost, heavy metal concentrations and types present may vary. Furthermore, the possible mobilization and leaching of the metals may depend on the organic content of the compost. In most cases, the levels of these heavy metals and their possible mobilization under normal or severe weather conditions are rarely addressed. This study investigates the levels of heavy metals such as Pb, Cr, and Cd in compost used for lawn gardens in Northeastern Alabama and their possible mobilization by weathering activities. Results depicting the metal concentrations and their possible mobilization will be presented. |
