Passive Sampling of Organic Contaminants as a Novel Approach to Monitor Seawater Quality in Aquarium Ocean Tanks

The determination of trace pollutants in seawater is challenging, and sampling is a crucial step in the entire analytical process. Passive samplers combine in situ sampling and preconcentration, thus limiting the tedious treatment steps of the conventional sampling methods. Their use to monitor water quality in confined marine environment could bring several advantages. In this work, the presence of organic contaminants at trace and ultra-trace levels was assessed in the Genoa Aquarium supply-and-treated water using Polar Organic Integrative Samplers (POCIS). Both untargeted gas chromatography-mass spectrometry and targeted liquid chromatography-tandem mass spectrometry were employed. The untargeted approach showed the presence of hydrocarbons, diphenyl sulfone and 2,4-di-tert-butyl-phenol. Only hydrocarbons were detected in all the samples. Nineteen emerging contaminants, belonging to different classes (pharmaceuticals, UV-filters, hormones and perfluorinated compounds), were selected for the target analysis. Thirteen analytes were detected, mainly in supply water, even though the majority of them were below the quantitation limit. It is worthy to note that two of the detected UV-filters had never been reported in seawater using the POCIS samplers. The comparison of the analytes detected in supply and treated water indicated a good performance of the Aquarium water treatment system in the abatement of seawater contaminants.

“…The origin of the plume is near the area of former distillation and storage facilities of crude benzene during World War I (28,29). We have previously reported that this benzene is presently discharging to the HBHA at about 30 kg/year (27). The lake is stratified year round with bottom waters always anoxic and sulfate-rich, while the epilimnetic waters are always oxic.…”

“…The HBHA receives benzene-contaminated groundwater input from an adjacent Superfund site (Industri-Plex). On Industri-Plex, large amounts of crude benzene (approximately 8000-21000 metric tons (27)) were converted to phenol during World War I. The groundwater just north of the lake contains a large benzene plume with peak concentrations near 60 µM (ca.…”

Predicting the fate of benzene in aquatic environments, and estimating corresponding human exposures, is critically dependent on knowledge of this carcinogen's biodegradation rate under the site-specific conditions. We used three approaches for quantifying this key fate process: (1) shortterm (hours) observations of benzene loss in laboratory incubations of representative water samples, (2) wholelake benzene mass balance studies, and (3) modeling of the temporal evolution of benzene vertical profiles in the lake. Our field site, the Halls Brook Holding Area (HBHA), continuously receives benzene input (about 20 µM or 1.5 ppm) into its anoxic hypolimnion via discharge of saline groundwater from an adjacent Superfund site (Industri-Plex in Eastern Massachusetts.) Using summertime, lake water samples in the laboratory, we found benzene was degraded in three metalimnion samples at rates between 1 and 2.5 d -1 . An epilimnion sample yielded a similar result, but no degradation was observed in another epilimnion sample. Losses were e0.04 d -1 in a sulfate-rich hypolimnion sample. Since benzene loss could be inhibited by filtration or with a mixture of poisons and antibiotics, it was apparently being biodegraded. In the whole-lake mass balance studies of benzene, it was found that approximately 80% of the benzene entering the lake was degraded during the water's residence in the lake. Vertical distributions of benzene in the HBHA water column indicated that the chief sink of benzene was located in the metalimnion. A twomonth progression of summertime profiles of benzene concentration vs depth was fitted well using a dynamic model, CHEMSEE, and assuming that the only sinks were epilimnetic flushing, water-to-air exchange, and biodegradation in a 0.4 m-thick metalimnetic layer at 2 d -1 . The biodegradation rate derived from such whole-system study appears more dependable than rates deduced from grab samples, and we suggest that we must learn to predict these intact-system rates.
