Application of the Ulva pertusa bioassay for a toxicity identification evaluation and reduction of effluent from a wastewater treatment plant

Abstract: A toxicity identification evaluation (TIE) based on Ulva pertusa spore release was conducted in 3 phases for the identification of the major toxicants in effluent from a wastewater treatment plant (WTP) and the receiving water in an adjacent stream. The toxicity of the final effluent (FE), as compared with raw wastewater, and primary and secondary effluent, showed a greater change over 12-monthly sampling events and appeared to have impacts on the toxicity of the downstream water with a significant correlation… Show more

“…This species can undergo a sudden and uncontrolled proliferation in response to environmental stress, such as climate change or water eutrophication [44], covering the water surface and decreasing biodiversity, even for other algae species [45]. Therefore, Ulva species are good candidates for ecotoxicology studies leading to the development of many bioassays, such as the UlvaTox bioassay which have been used in the biomonitoring of metals (e.g., silver, arsenic, cadmium, cobalt, chromium, copper, iron, mercury, manganese, nickel, lead, and zinc), formalin, diesel fuel, tributyltin oxide, and thiazolidinediones in municipal wastewater and industrial effluents [46][47][48][49][50][51]. The cell wall of U. lactuca is composed of a highly charged mucopolysaccharide, named ulvan, allowing the adsorption of those pollutants, such as GBHs [44,52].…”

“…This technology is now called IMTA and is based upon nutrient bioextraction, which provides important ecosystem services. Although a great deal of potential was shown in some studies (Kim et al 2015;Park et al 2018;Wang et al 2018), seaweed usage in these industries is either minimal or remains at the R&D stage. Therefore, it is important to diversify the application of seaweed resources in Korea.…”

“…Lemnatox determines the growth and pigmentation of the aquatic angiosperm Lemna [30] and the recently developed Ulvatox determines the release of zoospores from the marginal cells of the marine chlorophyte Ulva pertusa which is delayed under the infl uence of e.g. municipal or industrial wastewater monitored during a 96-h period [31,32]. Another approach is based on the real time image analysis of motile photosynthetic microorganisms monitoring motility, orientation with respect to light or gravity as well as cell shape [33,34].…”
