Abstract

Porphyrin derivatives (geoporphyrins or petroporphyrins) are naturally occurring compounds found in petroleum. They are structurally similar to chlorophyll and hemoglobin, and their presence in crude oil provides evidence for the biological origins of petroleum. These compounds, often complexed with metals like nickel and vanadium, are crucial for understanding petroleum’s formation and maturation processes. The goal is to use the U.S. Environmental Protection Agency’s CompTox Chemicals Dashboard to calculate and analyze properties of porphyrin derivatives from petroleum to understand their environmental fate. This involves using the dashboard’s publicly available data on chemical properties, environmental fate and transport, and toxicity to predict how these petroleum-derived porphyrins will behave in the environment.
