Evaluation of the effect of Sidoarjo mud on aquatic life using chromatophores and the microstructure of fish scales

The Sidoarjo mud is the first visible phenomenon of a mud volcano that occurs in a human settlement and which is subsequently channelled into a river. Clay, aluminium and iron were reported to be the dominant contaminants that could possibly come into contact with and accumulate on the surface of lo...
