Use of anesthetic conserving devices (ACD) for inhalational isoflurane sedation in Intensive Care Units (ICU) has grown in recent years, and healthcare professionals are concerned about isoflurane pollution and exposure-related health risks. Real-time measurements to determine isoflurane exposure in ICU personnel during short-term patient care procedures and ACD handling have not yet been performed.Isoflurane concentrations in the breathing zones of ICU staff (25 cm around the nose and mouth) were ...

Background MIRUS™ is a device for target‐controlled inhalational sedation in the ICU in combination with use of isoflurane, or sevoflurane, or desflurane. The feasibility of this device has recently been proven; however, ICU staff exposure may restrict its application. We investigated ICU ambient room pollution during daily work to estimate ICU personnel exposure while using MIRUS ™. Methods This observational study assessed pollution levels around 15 adult surgical patients who received volatile anaesthetics‐ ...

With the application of plate count methods and of the KOH-flexirubin test, bacteria belonging to the Cytophaga group were proved to occur regularly in samples from biological sewage treatment facilities. Generally, the percentage of Cytophaga colonies of the total heterotrophic colonies was lowest in the inflow sewage water as compared with the values found in activated sludge, trickling filter, and effluent samples. During an observation period of 16 months, the highest percentages of cytophagas ...

The assimilation and metabolism of CO 2 and acetate by Beggiatoa alba strain B18LD was investigated. Although B. alba was shown to require CO 2 for growth, the addition of excess CO 2 (as NaHCO 3 ) to the medium in a closed system did not stimulate growth. Approximately 24 to 31% of the methyl-labeled acetate and 38 to 46% of the carboxyl-labeled acetate were oxidized to 14 CO 2 by B. alba . The apparent V max values for combined assimilation and oxidation of [2- 14 C]acetate by B. alba were 126 to 202 ...

As has been pointed out in Chapter 1, the planktonic community is especially suitable for testing general ecological theories. Its spatial structure is relatively simple, and many species can be easily cultured and have short generation times. An experimental approach can be effective, particularly with those plankton showing the highest potential growth rates: the bacteria. Indeed, many important biotic interactions such as competition, commensalism, mutualism, predation, and parasitism have been ...

Abstract Flagellates were counted in five lakes by three different methods: live, epifluorescence, and MPN (Most Probable Number) counts. Live and epifluorescence counts always gave similar numbers. Epifluorescence counts provide the best estimate of total flagellate abundance and live counts are useful because they give a quick and easy estimate. MPN counts always gave lower numbers than the other methods. MPN, however, are interesting because they give an indication of the physiological status ...

The paradigm of the 'microbial loop' has became increasingly important for understanding the structure and function of aquatic ecosystems.Most of the microbial loop studies have focused on energy flow and nutrient cycling.Much less is known, however, about the importance of grazing as a force shaping the structure and community composition of planktonic bacteria.Theoretical considerations of predator-prey interactions suggest that predator evasion mechanisms should have evolved for bactena in the ...

In a series of grazer‐gradient and dilution microcosm experiments, we compared grazing and nutrient mineralization by naturally co‐existing crustacean and microzooplankton assemblages from mesoeutrophic Lake Kinneret. Across two distinct seasonal plankton assemblages, microzooplankton dominated both phytoplankton and bacteria grazing and nitrogen (N) and phosphorus (P) mineralization. Mass‐specific ingestion rates by microzooplankton were ~20 times higher than ingestion rates of crustaceans. Although ...

Soft sediments are often highly polluted as many of the toxic chemicals introduced into surface waters bind to settling particles. The resulting accumulation of pollutants in the sediments poses a risk for benthic communities. However, pollution induced changes in benthic communities have been difficult to determine when using macro-invertebrates as bioindicators, as these organisms are often absent in soft sediment. The present study therefore examined the ability of meiofaunal organisms, specifically, ...

In order to obtain a first insight into the characteristics of pelagic, littoral and profundal bacterial communities and their potential role for the degradation of organic matter in the deep prealpine Lake Constance, we compared the seasonal dynamics of bacterial abundances and activities during the annual cycle in the epilim- netic water of a central station as well as in surface layers of sediments at a central pro- fundal and a littoral site. For this purpose, bacterial abundances (DAPI counts), ...

Shells from adult specimen of the benthic ostracodes Limnocytherina sanctipatricii and Leucocythere mirabilis selected from a 8.7 m long piston core provide continuous stable oxygen and carbon records for the past approximately 16 ka. Oxygen isotopes from both species show identical values and track the general North Atlantic and European temperature history since deglaciation in great detail. Values of ostracode δ18O values suggest that about 16 cal ka the average annual air temperatures were about ...

Between February and April 2004, 48 sites in Lake Constance (Germany) were investigated to determine the distribution of the meiobenthic community, including 16 sites from the sub-littoral (13 -30 m water depth), 16 sites from the profundal (31-99 m) and 16 sites from the deep profundal (100-250 m). Lake-wide analysis showed no simple distribution pattern, but rather a heterogenic meiobenthic community composition, with nematodes representing the dominant group (48.7 %), followed by rotifers (27.7 %), harpacticoids ( ...

Previous studies analysing the chemical composition of profundal sediments of Lake Constance suggest a overall large contribution of allochthonous material to total sedimentation but also a large spatial variability in the relative importance of allochthonous versus autochthonous sedimentation. Here we analyse sedimenting particulate organic matter (POMsed) during an annual cycle at two sites differing in their position relative to the major inflow and thus in their proposed contribution of allochthonous ...

One of the largest fluxes of carbon in most of the ecosystems is that from the detritus to microorganisms. Microbial ectoenzymes play a basic role in the degradation of detritus. However, the role of ectoenzymes in dependence of the detritus composition has not been studied. In a microcosm experiment we have followed the development of nine ectoenzymatic activities and hydrolytic bacteria during the degradation of four sources of detritus (macrophytes, algae, leaves and chitin). Throughout the degradation ...

Combined sewer systems collect surface runoff as well as wastewater of industrial and domestic origin. During periods of heavy rainfall the capacity of the sewer system is exceeded and the overflow is discharged into receiving waters without any treatment. Consequently, combined sewer overflow (CSO) is considered as a major source of water pollution. This study investigates the effectiveness of a retention soil filter (RSF) for the removal of micropollutants as well as facultative pathogenic and antibiotic ...

It determines chironomid and oligochaete abundances and carbon sources at two sampling sites with different allochthonous contributions in the deep oligotrophic waters of Lake Constance.

The project focuses on the efficiency of combined technologies to reduce the release of micropollutants and bacteria into surface waters via sewage treatment plants of different size and via stormwater overflow basins of different types. As a model river in a highly populated catchment area, the river Schussen and, as a control, the river Argen, two tributaries of Lake Constance, Southern Germany, are under investigation in this project. The efficiency of the different cleaning technologies is monitored ...

During summer, methane concentrations measured in the surface water layers of Lake Constance were oversaturated by as much as forty times. Although methane concentrations were less than saturated in the upper water column during the winter of 1994/95, the concentrations increased to more than 2000 nl/l (90 nM) in July. The observed spatiotemporal distribution patterns strongly suggest biogenic production of methane in oxic epilimnetic water layers whereas advective transport from the littoral to ...
