In this list, “metals” denotes arsenic, cadmium, copper, chromium, iron, mercury or lead; “organic contaminants” were chloropyrifos, naphthalene, DDT and polycyclic aromatic hydrocarbons (PAHs); and “water quality parameters” were extremes of temperature, salinity, pH, turbidity, dissolved oxygen, chlorophyll a, and ammonia. Abbreviations: MA, microarray; SSH, suppression subtractive hybridization.
