Either DDT or polychlorinated biphenyls were added to mixed cultures containing a marine diatom and a marine green alga that were sensitive and resistant, respectively, to these organochlorine compounds. The diatom grew faster and was therefore dominant in control cultures, but its dominance diminished in treated cultures, even at concentrations of chlorinated hydrocarbons that had no apparent effect in pure cultures. Such stable pollutants could disrupt the species composition of phytoplankton communities, thereby affecting whole eco-systems.
滴滴涕（DDT）或多氯联苯被添加到含有一种海洋硅藻和一种海洋绿藻的混合培养物中，这两种藻类分别对这些有机氯化合物敏感和具有抗性。硅藻生长得更快，因此在对照培养物中占主导地位，但在经过处理的培养物中其优势地位减弱，即使在对纯培养物没有明显影响的氯代烃浓度下也是如此。这类持久性污染物会扰乱浮游植物群落的物种组成，从而影响整个生态系统。
