Contamination Assessment Reports (CARs) are typically developed from the results of sampling and chemical analysis of physical parameters (e.g., soil, groundwater, surface water, sediments, free product), an evaluation of the spatial extent of contamination, and model predictions of potential temporal changes from the current condition.  Rarely are the bioaccessibility or bioavailability of so-called contaminants-of-potential-concern (COPCs) considered; yet, without this information, site assessments are, at best, incomplete, or limited in their capacity to interpret potential human or ecosystem impacts.  More importantly, a lack of information on biotic response to COPC exposures can result in either false positive or false negative conclusions of site condition and ultimate risk characterization.  Sampling physical factors alone assumes we know the cause and effect relationship, understand possible synergistic (or antagonistic) effects of more than one physical factor and generally assumes continuous exposure.  Although adverse effects due to synergistic interactions of multiple stressors can be missed (false negatives), more often the common practice of comparing discrete physical parameters to regulatory "bright lines" leads to the overprediction of site hazards (false positives).

The time and cost of using conventional analytical approaches can significantly restrict the number of samples analyzed for environmental assessment and monitoring. Because the quality of environmental management decisions depends upon the accuracy of monitoring approaches employed, the Environmental Protection Agency (EPA) is seeking effective and cost-efficient techniques to assess the impact of environmental stressors on the human health and the ecosystem, and to monitor the effect of remedial activities. The use of biosensors emerges as a powerful new approach for environmental monitoring. In addition to an internal research and development program, EPA supports the advancement of biosensor-related science and technology through Science To Achieve Results (STAR), a competitive extramural research grants program. Through the STAR program, EPA is funding research on the application of biosensors for the assessment of exposure and toxicity in humans and ecosystem, and for environmental monitoring of remedial technologies. Biosensors and biomarkers STAR research results will be presented and EPA research priorities in this emerging area will be discussed. Presentation will focus on the development of biosensors for site characterization and monitoring, biomarkers for the assessment of exposure and toxicity, and ecological indicators.

Serotoninergic system activity is shown to be highly vulnerable to the impact of environmental pollution (Garcia et al., 2001). The importance of these studies is due to the fact that serotonin is involved in regulation of cell proliferation and differentiation (Couper et al., 1996; Mercer et al., 1996), so significant changes in serotonin turnover might bring to such severe pathologies as inborn abnormalities and cancerogenesis both in animals and humans. The serotonin-modulating anticonsolidation protein (SMAP) was identified and purified from the rat brains and appear to consist of two subunits of 126 and 60 kDa (Mekhtiev, 2000). This protein presents linear correlations with the serotonin content in the rat brain. Determination of the SMAP content in the fish liver by the ELISA-test with application of the anti-SMAP immunoglobulins was used to evaluate the serotoninergic system activity on the postsynaptic level. The mutagenesis level in fishes was evaluated by micronucleus test by counting the micronuclei amount per each 1000 erythrocytes. It was shown that goldfish (Carassius auratus) exposure to the crude oil polluted water at concentrations of 0,1 and 0,5 ppt for 5 days leads to increase of the SMAP content in the goldfish liver relatively to the intact fishes (p<0,001). The micronucleus test showed no differences between groups under 0,1 ppt concentration, and increase in the micronuclei amount under 0,5 ppt concentration. Besides, the SMAP content was evaluated in the liver of the gobies (Neogobius fluviotilis) dwelling in the Caspian Sea. The gobies were caught in one clean and two polluted littoral zones of the sea with increasing level of contamination. The analysis showed that the SMAP contents in the tissues of the fishes dwelling in the polluted zones were significantly lower (p<0,01) than in the specimens from the clean one. However, the micronucleus test didn't reveal significant differences between the fishes from both zones. So, determination of the SMAP content in animal tissues may be used as a sensitive and reliable indicator of the environmental pollution.

The Effect of Mountain Forest Decline on Staphylinid Beetles in Central Europe

Staphylinid beetles belong to one of the most numerous group of invertebrates living in the soil and on soil surface. In Central Europe they occur in mountain forests which were negatively impacted by air pollution, particularly by sulphur dioxide, in the last fifty years. The long term changes of staphylinid communities (1983-2003) were indicated in sensitive mountain ecosystems. The main factors influencing the beetle communities (habitat and soil characteristics) are described. The characteristics of invasive species, which colonize declining forests are provided.  The critical stage of staphylinid communities is determined in impacted mountain environment. There is discussed the  potential possibility to restore beetle communities after the ten last years, when the  decreasing of air pollution was found.

Development and Use of Animals as Air Pollution Biomarkers and Bioindicators in Central Europe: History and Status

Since the late 1960s, there has been a formal interest and research into the development and use of biomarkers and bioindicators of air pollution. The development and use of markers and indicators resulted from a political prohibition of being able to study the effects of air pollutants on human health.  Central Europe from the 1950s through the 1980s was the scene of acute and chronic air pollution from industrialization. Researchers from different institutes and universities conducted extensive studies on biomarkers and bioindicators of air pollution.  Biomarkers included such responses as changes in the chemical composition of lens and changes in the blood chemistry of wild hares.  Bioindicator organisms included urban birds whose nesting is sensitive to different levels of air quality and pheasants which exhibited different levels of nematode infection in urban and industrial regions compared to agricultural regions.  These and other biomarkers and bioindicators were incorporated into monitoring programs.  This paper will review the types and application of air pollution biomarkers and indicator developed and used in Central Europe.  The present status of biomarkers and bioindicators will be presented.

Neurological Effects of TCE in Groundwater and Soil in Lisle, Illinois

Twelve residents living adjacent to a site of TCE contamination of the groundwater (68,000 ppb) and soil (680,000 ppb) were evaluated as to the presence of TCE-induced neurologic dysfunction with history, neurologic examination, and nerve threshold measurements and olfactory testing.  Where clinically appropriate, additional testing was performed with somatosensory evoked responses, nerve conduction velocities, electroencephalogram, visual evoked responses, brainstem auditory evoked responses, P300 responses, Millon Clinical Multiaxial Inventory-III, Minnesota Multiphasic Personality Inventory-2, Beck Depression Inventory, Zung Depression Scale, Paulhaus Deception Scale, TOMM, Validity Profile Indicator, Strub and Black Mental Status Examination, Mini Mental State Exam, Poppelreuter Task Test, Trail-Making Subtest of the Halstead Reitan Battery, and a series of olfactory and gustatory testings.  On sensory nerve threshold measurements, 11 (91%) demonstrated bilateral abnormalities.  Five (41%) demonstrated preferential trigeminal nerve involvement, a marker for TCE-induced neurologic damage.  Diagnosis in these five included TCE-induced:  polyneuropathy (4), cephalgia (3), limbic encephalopathy (2), encephalopathy (1), subclinical encephalopathy (1), subclinical hyposmia (1), subclinical polyneuropathy (1), optic neuropathy (1), and anosmia (1). 

In the presence of substantial TCE in soil and ground water, trigeminal nerve threshold measurements may be useful as a biologic marker for TCE exposure.
