Lead-safety Message: Don’t let lead wheel weights or bullets or fishing sinkers or lead paint or lead oxide powder from vehicle lead acid batteries go from the city to the surf then settle in the sediments. Lead harms marine life.

Reference for Lead-Safety Message: Lead in the Environment – US Geological Survey Professional Paper 957: Abundance of Lead in Rocks, Sediments, Fossil Fuels, and Minerals (1970) – includes that 15 parts per million (ppm) is the average lead concentration in the earth’s crust, but 60 ppm is the average found in deep sea muds.
