Effects of Halogenated Hydrocarbon Aquatic Organisms

Abstract

This research dealt with several experiments evaluating the response of different algal species towards selected halogenated hydrocarbons. Two groups of algal species were assayed. The response of the algal species towards the chemical was evaluated under various growth medium composition. With respect to changes in the growth medium composition it was clear in this work that depletion of nutrients nitrogen or phosphate in case of green algal species or silicate in the case of diatoms lowers the percentage of survival of the organism. Green algal species were more or less tolerant to changing growth media composition than diatoms. In conclusion, when bioassaying the halogenated hydrocarbons, various algal species as well as growth medium composition should be considered.
