“…With the EC50 values (with 95% CI) of 0.076 (0.049-0.094) mg l -1 to diuron, the end-point used in this study is less sensitive than that reported previously with U. intestinalis (0.003 mg l -1 for germling growth) and U. pertusa (0.010 mg l -1 for motility of spores) [17,18]. EC50 values (with 95% CI) of atrazine toxicity were 0.180 (0.165-0.195) mg l -1 for the new method.…”

“…In a study on the green macroalga U. intestinalis, EC50 values (with 95% CI) derived from inhibition of growth and Fv/Fm were 0.143 and 0.650 mg l -1 , respectively [18]. In the case of the DMSO, which is increasingly used in industrial areas, the toxic effects in marine macroalgae are not well studied.…”

“…Two other triazine herbicides with similar structures (not registered as booster biocides yet), atrazine (13), and prometryn ( 14), significantly depressed the photosynthesis efficiency of U. pertusa (Gao et al, 2017). Diuron was proven effective on settlement inhibition on U. pertusa spores, with EC 50 of 21 µM (Shin et al, 2015). Triazine herbicides and diuron are difficult to degrade in seawater and sediment (Voulvoulis et al, 1999;Thomas and Brooks, 2010), thus they can be accumulated by marine organisms such as sea cucumbers (Tian et al, 2013;Ren et al, 2014), and eventually threaten human health.…”

“…According to the thesis of Wendt (2013), the EC 50 values to U. lactuca germination inhibition were 38 and 47 nM, respectively, which were both more effective than DCOIT, tolylfluanid and TPBP mentioned above. Shin et al (2015) reported the inhibition effects of CuPT and ZnPT on the spore motility and germination of U. pertusa. Another zinc complex fungicide, zinc dimethyldithiocarbamate (ziram) (20), has an inhibitory effect on the germination of U. pertusa spores (Shin et al, 2015), with the half-life less than 1 day (Konstantinou, 2006).…”

The green algae, Ulva spp., have been causing environmental problems worldwide, e.g., green tides and biofoulings. Green tides resulted from bloom floating Ulva have caused substantial economic losses. Ulva foulings increase the maintenance cost of marine facilities and contribute to the biomass of floating algae. Chemical methods are generally very inexpensive and convenient for suppression of Ulva spp. during their early life stages, thus solving the green tide and fouling problem at the source. In this paper, classical chemical methods that have been or are in use and emerging chemical methods under research are systematically reviewed. The advantages, disadvantages, mechanisms, and applications of these methods are also summarized. Highly toxic reagents are used in classical chemical methods, including oxidants, acids, heavy metal compounds, and synthetic biocides directly used or applied in antifouling coatings to kill or inhibit Ulva effectively. However, these toxic reagents have a high risk of resulting in secondary environmental problems. In order to minimize other environmental impacts while solving the current problem, emerging, and environmentally friendly chemical methods have been developed, such as the utilization of degradable natural products (mainly allelochemicals) and semi-natural products for Ulva inhibition and fouling control, and the use of flocculating agents to prevent microscopic propagules from germinating. All these chemical methods provide a promising direction for the prevention and control of Ulva.
