Occurrence and Formation of Trihalomethanes in Marine Aquaria Studied Using Solid-Phase Microextraction Gas Chromatography‐Mass Spectrometry
The occurrence and formation of chlorinated and brominated trihalomethanes (THMs) were studied in artificial saltwater and natural seawater marine aquaria as well as in groundwater and surface waters. A new headspace solid-phase microextraction method was used, which included gas chromatography‐mass spectrometry and provided method detection limits of less than 0.1 µg/L, with a signal-to-noise ratio of 3 to 5. The results showed that disinfection by using either chlorine or ozone caused a significant formation of THMs in situ. Speciation of the THMs was a strong function of the water matrix, with initial bromide concentrations playing a pivotal role. These results provide a tool for understanding and monitoring the formation of key disinfection byproducts in marine aquaria that may cause respiratory, eye irritation, or other health concerns.
