Abstract

This paper describes the result of a toxicity test by means of a shaking culture on municipal sewage effluents using seaweed as a test living organism. Dead cells of porphyra yezoensis (nori) have emerged more specifically with the addition of non-disinfected secondary treated water at about 1% and with the lower the salt content. This phenomenon is thought to be an antagonism among growth accelerating substances for porphyra thallus, growth inhibiting substances, and salt content, one of the important characteristics of non-disinfected treated water. As a result of culture test on ripe seawater added with chlorine-disinfected secondary treated water, it was found that the growth of porphyra yezoensis (nori) is governed completely by concentrations of free chlorine added to the treated water, but very little by the treated water addition factor. Substances with very strong growth inhibition power, including NH4Cl, are generated in the chlorine-disinfected secondary treated water. It was disclosed that growth ratios of giant kelps at different factors of addition of non-disinfected secondary treated water change with the sampling time; water quality of the treated sewage water changes from one hour to another; and there are two time bands that show the growth ratio of about the same  More>>
