Fishing sinker
Seabed of Bosphorus full of toxic sinkers: Marine biologist
The seabed of the Bosphorus is full of sinkers that have fallen off from fishing rods, causing massive risk to human lives and the ecosystem, a marine biologist has warned.
"Those sinkers are made of lead that can dissolve in time in salty waters," Gülşen Altuğ from Istanbul University told Demirören News Agency on March 16.
