Abstract
The primary source of 2,4,5-trichlorophenol (2,4,5-TCP) contamination in the environment is
industrial effluents. The compound itself is used as a germicide and also as a reagent in the
synthesis of certain herbicides, disinfectants, and insecticides. In addition, 2,4,5-TCP is also
formed as a by-product of the chlorination processes used by paper mills, and thus is present in
paper mill effluents.
The purpose of this study is to determine and report the toxicities of 2,4,5-TCP to several
freshwater organisms. The organisms used were an annelid (Lumbriculus variegatus (Muller)), a
coelenterate (Hydra sp.), an. amphipod (Gammarus pseudolimnaeus), and a mayfly nymph (Leptophlebia
sp.).
