This project focuses on tracking heavy metal life cycle pathways using input-output methods. Researchers and students, including faculty from Economics and Civil Engineering fields, are updating heavy metal estimates and understanding product and sector flows throughout multiple life cycles. Key papers address significant issues like lead management in automobile batteries and cadmium material cycles in the U.S. The project also includes outreach initiatives and educational resources aimed at raising awareness about heavy metals and their environmental implications.

Progress to Date • Updated www.eiolca.net to include 1997 benchmark. • Initial heavy metal estimates of product and sector flows over multiple life cycles. • Comparison of metal emissions databases and ambient air quality. • Papers: • Lead Management Issues and Automobile Batteries • Closing the Loop on Cadmium: An Assessment of the Material Cycles of Zinc and Cadmium in the U.S.
Broader Impacts • www.eiolca.net still receiving heavy use. • Continuing public concern for heavy metals in the environment. • Apprenticeship secondary school outreach program on life cycle assessment. • Design work for kid.eiolca.net.
