Mercury from the ocean through fog? A conceptual diagram

This is a figure that was made for the recent paper of mine. It shows how we believe that coastal fog is enriched in methylmercury (the most toxic kind of mercury). Rainwater originates high in the atmosphere and is not enriched in methylmercury. The forests that intercept the fog water then receive fog drip containing methylmercury, which is effectively taken up by lichen and maybe other plants. The deer eat the lichen and the mountain lions eat the deer. What is the risk to humans from this process? That is what we hope to find out.
