A Tale of Fish and Stones

Hank Hogan

For Vincent P. Palace, head of the Environmental Center for Research on Pesticides at Freshwater Institute in Winnipeg, Manitoba, Canada, success is not a fish tale. Instead, it is a fish otolith — a stonelike structure in the ear composed of calcium carbonate and a protein matrix. Examining otoliths using laser ablation inductively coupled plasma mass spectrometry is helping Palace and his colleagues there and at the University of Manitoba in Winnipeg and at Alberta Sustainable Resource Development in Edson, Canada, settle a pollution question. Researchers used otoliths from rainbow...Read full article

    laser ablation
    Laser ablation is a process that involves the removal or erosion of material from a target surface using laser energy. This technique is widely used in various scientific, industrial, and medical applications. The intense energy from the laser beam interacts with the material, causing it to undergo physical and chemical changes, ultimately leading to its removal. Key features of laser ablation include: Laser energy: A high-energy laser beam is directed onto the surface of a material. The...
