“…In a paper focusing on the measurement of oxidants in ozonated sea water, Crecelius (1979) quoted a 48-h EC 50 of 30 mg BrO − 3 liter −1 based on the development of larvae of the Pacific oyster, C. gigas (no corresponding NOEC value was reported). In contrast, Stewart et al (1979) Effects on fish. All of the reported data on the effects of BrO − 3 on fish relate to estuarine or marine species (Table 3).…”

“…As a result of the literature review identifying widely differing values in the toxicity of bromate to oyster embryos, together with uncertainty over the experimental methods and analytical purity of the test samples used for previous published studies (Stewart et al, 1979;Crecelius, 1979), it was considered necessary to reevaluate these data using the more comprehensive regulatory oyster embryo development assay protocol. A total of two studies were therefore undertaken at this laboratory to assess the effect of bromate on the embryo development of the Pacific oyster (C. gigas).…”

“…Its effect occurs by oxidization of organic molecules in the microorganism's membranes, directly by O 3 or by its highly reactive degradation product, HO (hydroxide). As a result, the membrane is disrupted and the microorganism dies (Doroszkiewicz et al 1994;Stewart et al 1979;You et al 2000).…”

Ozone gas diluted in water has been shown to produce significant results in terms of the elimination of microorganisms. Streptococcus mutans is the etiologic agent of dental caries. Methods using water containing ozone and an ultrasonic cleaner were employed for the disinfection of a curette. Streptococcus mutans was grown in a selective medium. The curette was submitted to disinfection by water containing ozone, by ultrasound, and then both techniques were combined. The results show that either method produced a significant microbial reduction, but the efficacy of both methods combined was greater. This method of disinfection proved to be both viable and cheap.

“…Oxygen consumption (>L 02/g/hr) was measured in crabs before and after acute (96-hr) exposure to CPO (0.13, 1.65, and 4.00 mg/L), phenol (1,16, and 32 mg/ L), and the CPO-phenol mixture (2,20, and 80 mg/L TTU). Following exposure, crabs were depurated in uncontaminated seawater (25°C and 25 ppt salinity) for 96 hr, and respiration measurements were repeated.…”

“…Although numerous studies have documented the adverse individual effects of CPO and phenols on aquatic organisms (15)(16)(17)(18)(19)(20), very few studies have examined and compared the adverse effects of halogenated phenolic mixtures. The purpose of this study was to compare the lethal (LC50) and sublethal (respiration and phenol uptake) effects of acute exposure to CPO, phenol, and a CPO-phenol mixture on the estuarine mud crab, Panopeus herbstii.…”

The mud crab, Panopeus herbstii, was acutely exposed (96-hr) to chlorine-produced oxidants (CPO), phenol, and a CPO-phenolic mixture (1:1) to determine lethal and sublethal effects. The 96-hr (LCro) values were determined for each individual compound and mixture. Additionally, whole-animal respiration rates were measured following acute exposure to sublethal concentrations of each compound or mixture. Phenol uptake/depuration rates were measured in the phenol and CPO-phenol mixture concentrations. Sublethal studies indicated that only acute exposure to sublethal concentrations of CPO caused altered respiration rates. After 96-hr depuration, metabolic rates in all CPO-exposure crabs generally returned to control rates. Uptake/depuration rate studies indicated significantly lower phenol uptake rates in crabs exposed to the CPO-phenol mixture. These findings suggest that the less-than-additive toxicity of the CPO-phenol mixture may result from lowered uptake/depuration rate kinetics and indicate that the discharge of chlorinated-phenolic waste may not result in additive and/or synergistic interactions, but rather in less-than-additive effects on decapod aquatic species.
