Abstract: An embodiment of the invention provides a system for toxicity identification in water. The system includes a cell maintenance device having a cooling component that maintains an internal storage area of the cell maintenance device within a temperature range of 4 degrees Celsius to 25 degrees Celsius. Fluidic biochips in the cell maintenance device include one or more testing components for receiving living poikilothermic cells and at least one water test sample. A test unit receives the fluidic biochips and monitors a response to exposure of the poikilothermic cells to the water test sample. In at least one embodiment, the test unit is able to identify the degree of toxicity of the water sample within 60 minutes of receiving the fluidic biochip.
