In marine systems, silver is regarded as being one of the most toxic and readily accumulated metals, and is known to be taken up and accumulate within marine invertebrates, fish, phytoplankton and seaweeds. Reported open ocean concentrations of silver range from 0.1 – 2 ng L-1 while silver concentrations in coastal waters are typically 5 to 10 times higher than open ocean values (0.1 - 50 ng L-1). The determination of silver in marine and coastal waters presents several challenges including low concentrations and matrix complexity of seawater, which creates interferences and other challenges for many instrumental techniques creating a …
