Penobscot Bay Aquaculture and Heavy Metal bioaccumulation

Sugar Kelp  and heavy metals

Excerpt: "Here, we present baseline information about concentrations of arsenic, cadmium, lead, and mercury, in both wild and farmed sugar kelp from the New England region. 

We interpret our findings based on proximity to potential sources of contamination, location on blade, and available heavy metals standards. 

Contrary to our expectations, high concentrations were widespread in both wild and farmed populations, regardless of proximity to contamination. 

We find, like others, that cadmium and arsenic consistently reach levels of regulatory concern, and that dried seaweeds could harbor higher concentrations compared to raw products. 

We also share unique findings that suggest some toxins concentrate at the base of kelp blades. "
