Shellfish poisonings have posed severe risks to human health globally. The Canadian Sanitation Program was established in 1948 monitor the toxin levels at shellfish harvesting sites along coast of six provinces Canada. Domoic acid has been a causal for amnesic poisoning, and macro-scale analysis temporal spatial variation domoic Canada's conducted this study. We aggregated by week blue mussel (Mytilus edulis) soft-shell clam (Mya arenaria) samples, respectively, over one-year scale. subsequent application Functional Principal Component Analysis unveiled that magnitudes seasonal peaked DA around early summer, spring, or mid-fall formed largest mussels coastlines British Columbia Prince Edward Island calms those New Brunswick Nova Scotia.

Downstream correlation analyses further discovered that, most sites, strongest correlations negative between precipitation as well inorganic nutrients (including nitrate, nitrite, phosphate, silicate) on one side few weeks afterward other. These findings indicated associations poisoning environmental stresses.
