Abstract

Inhibition of germination of zygotes of the fucoid macroalgae Hormosira
banksii and Phyllospora comosa and zoospores of the laminarian
Macrocystis angustifolia was used as an end-point to assess the toxicity
of three sewage effluents of differing quality. For each species,
between-assay variation was low and results of tests with the reference
toxicant 2,4-dichlorophenoxyacetic acid suggested that results are
reproducible, especially in P. comosa. Each species showed a greater
sensitivity to primary-treated effluent than to secondary-treated
effluent, and higher variability in response to the primary effluent.
High variation in response for each species when exposed to the primary
effluent (compared with that for the secondary effluent) is presumably
indicative of variation in quality of the primary effluent. The capacity
to reproduce these assays, the sensitivity of species employed, and the
ecological relevance of germination as a toxicological end-point suggest
that germination tests of this nature may be useful in biological
testing of effluent quality at discharge sites in south-eastern
Australia.
