Abstract: The sensitivity of sea urchin egg fertilization was tested in waters of various degrees chlorinated and unchlorinated domestic sewage. Chlorine in sewage, especially diluted sewage, was found to strongly inhibit sea urchin fertilization. Removal of chlorine suggested that there were other pollutants present in sewage effluent. The sea urchin fertilization bioassay may be useful in indicating pollution though it cannot act a the sole indicator of water quality.
