Abstract
Copepods are tiny (~1 mm) crustaceans belonging to zooplankton which is a major trophic link in the aquatic food web. Their biomonitoring is ecologically relevant since their biological process and demoecological impairment must be read as early signs of hazard occurring in the environment, before higher levels organisms are concerned.
Highlights
-
Water quality assessment is more efficient when it relays on early warning systems
-
Copepods, occupying lower trophic levels, are considered as environmental sentinels in aquatic ecosystems
-
Digestive gut of animals exposed to either essential or non-essential metals gave evidence of a dose-dependent cell apoptosis, even at environmentally exposure concentration
-
Copepod cell sensitivity to metals may open up a horizon to explore cell-based biosensing techniques for water quality assesment
