Early studies of the rate of opal dissolution in the laboratory indicated that the dissolution rate of acid-cleaned planktonic diatoms varied as a linear function of the degree of undersaturation (e.g., Hurd, 1973 Lawson et al., 1978).

Domoic acid is a naturally occurring excitatory amino acid that was identified as the toxin responsible for an outbreak of amnesic shellfish poisoning that occurred in Canada in 1987 following consumption of contaminated blue mussels (Mytilus edulis) [1] as well as numerous other outbreaks worldwide. The parent compound is a tricarboxylic amino acid produced by certain marine organisms, the best characterized of which are the red alga Chondria armata and the planktonic diatom Nitzschia pungens, although other species are also known to produce domoic acid (for review, see Reference 2). 

Planktonic diatoms are abundant in ECS, with Pseudo-nitzschia deli-catissma, P. pungens, and Melosira sulcata being the dominant species (Gao et al., 2003). Phytoplankton abundance was low (<5x10 cells/L) in the coastal areas, where the SPM was high (>100 mg/L), and the dominant species are...

In seawater silicon occurs predominantly as reactive silicate, the dissolved ions of orthosi-licic acid, but also as inorganic and organic fractions of suspended material, particularly originating in plankton diatoms (see Section 10.1). Die concentration of suspended silicon is very small, usually not exceeding a few /imol/L. Deating with an alkaline persulphate solution will break down these silicon complexes and convert them into reactive silicate. Only when large amounts of clay material are present a carbonate fusion is needed.
