- NIVA-rapport 
Analyses of various chemical properties in sediments collected in various projects during the period 1984 - 93 was reviewed to establish characteristic environmental gradients at fish farm locations. The multiple property gradient was used to assess the effects of farming activities at five locations along the coast of Norway north of 63N. In addition to separate evaluations of each property, integrated pollution indexes derived from electrode measurements of Ph, pE and pS were calculated and compared to pollution indexes from the concentrations of N, P, Zn and Cu in the top layer of the sediments.
