The profile of contamination with alkylphenol ethoxylates of some Israeli watercourse rivers and their sediment layers

The ‘hard’ non-biodegradable alkylphenol ethoxylates (APEOs) nonionic surfactants are environmentally persistent and widely used worldwide. The aim of this work is to determine the total concentration and the homological distribution in rivers and there sediments, in central Israel. The concentratio...

The aim of this work is to determine the total concentration and the homological distribution in rivers and there sediments, in central Israel.
