@article{Hiroyuki Ii_2017, title={AS, SR, ZN, FE, MN, PB AND CU CONCENTRATIONS OF SEAWEED AT THE KII PENINSULA, JAPAN}, volume={10}, url={https://geomatejournal.com/geomate/article/view/1999}, abstractNote={<p>Seaweed from locations ranging from Osaka Bay facing the metropolis to the southern top of<br>the Kii Peninsula facing the Kuroshio Current at the Kii Peninsula were measured for concentrations of arsenic<br>(As), strontium (Sr), zinc (Zn), iron (Fe), manganese (Mn), lead (Pb) and copper (Cu). Except for one location<br>at Kanayama neighboring a closed Pb mine, metal concentrations in seaweed were variable but their average<br>values agreed with the world data. Therefore the influence of the Kuroshio Current water and Osaka Bay water<br>on metal concentration in seaweed was found to be small. As and Sr concentrations in brown seaweed were<br>higher than those in red and green seaweed at the Kii peninsula except at Kanayama, Fe concentrations in<br>green seaweed were higher than those in brown and red seaweed and Zn, Mn, Pb and Cu concentrations in<br>brown, red and green seaweed were all the same. Total Fe, Zn, Mn, Pb and Cu loads of mine waste water from<br>the closed mine into the Kanayama Bay were 4,000 to 6,000, 3,000 to 5,000, 180, 20 and several kg per year.<br>Zn and Fe concentrations in seaweed at Kanayama were remarkably high being 10 to 100 times that of the<br>world value. Mn and Pb concentrations in seaweed at Kanayama were 10 times higher than the world values.<br>Cu concentrations of red and green seaweeds at Kanayama were little higher than the world values.<br><br></p>}, number={22}, journal={GEOMATE Journal}, author={Hiroyuki Ii}, year={2017}, month={Feb.}, pages={2036–2042} }
