Sample series composed same season similar size/age intended avoid biological biases.

Conversely, time their ratios indicate a constant proportion natural sources since 1980s. In contrast, progressively developing locales (urbanization recreational boating) Arcachon Vilaine bays shift positively time, along increasing concentrations. finding suggests gradual augmentation bioaccumulation time.
