The article presents a study which investigates the distribution of bioaccumulated metals in the marine copepod Tigriopus brevicornis and its subsequent transfer implications in the food web in Brittany, France. It says that samples of copepods were collected and exposed to Copper (Cu), Zinc (Zn), Nickel (Ni), Cadmium (Cd), Silver (Ag) and Mercury (Hg) in water for 1-14 days. It states that three concentrations were tested for each mental, and desorption tests were conducted to evaluate the fraction of metals desorbed from the exoskeleton. The study found a high variability in bioaccumulation ability and that metals bound onto the exoskeleton were desorbed to different extent. It adds that metals such as Cd, Ni, and Zn are more likely to be transferred along a food chain. |
