研究發現，棲息在沿海地區霧帶內的聖克魯斯山美洲獅，體內的汞(俗稱水銀)含量比生活在霧區外的美洲獅高三倍。霧氣中的污染物被地衣吸收，進入草食性的鹿體內，再帶到像美洲獅等捕食者，影響這些陸生動物的繁殖能力及生存。汞是全球性的污染物質，已以不同形式進入生態系統及食物鏈。

in Santa Cruz Mountains, the mercury levels in pumas that live in the fog zone are three times higher than pumas that live outside. Lichen absorbs mercury in marine fog, then the mercury makes it way up to deers and then the predators, affecting these terrestrial animals’ survival and reproduction rates. Mercury is a global pollutant and has entered eco systems and food chain in different ways.
