Variation in some element contents of water hyacinth due to cadmium or nickel treatment with or without anionic surface active agents

Abstract
The changes in some metal components of water hyacinth by exposure to cadmium, nickel with or without surface‐active agents are determined. Metal contents of Cd, Ni, Al, Ca, Si, Mn in tops and roots were changed in relatively short time by treatment with Cd or Ni. The values of concentration factors are reduced in both tops and roots under the presence of the anionic surface‐active agents.
