“…A Sediment Bioassay Group performed a wide variety of bioassays on sediment samples from these transects. Both solid phase and elutriate techniques were used for sediment testing (Chapman et al 1992 European infaunal amphipod species when exposed to identical sediment samples. The amphipod bioassays were performed at 4 laboratories: the U.S. Environmental Protection Agency Research Laboratory, Newport, Oregon, USA (EPA), the EVS Consultants Laboratory, North Vancouver, BC, Canada (EVS), the Water Research Centre, Medmenham, UK (WRC) and the Rijkswaterstaat Tidal Waters Division laboratory, Middelburg, The Netherlands (TWD).…”

During the Bremerhaven Workshop, sediment samples from 2 pollution gradients in the North Sea were tested in a 10 d static bioassay with infaunal amphipods. One gradient was downstream from a former drilling site, the second was offshore of the Elbe-Weser plume in the German Bight. Four participating laboratories used basically the same technique to test sediment toxicity with 1 of 3 different amphipod specles: Rhepoxynius abronius, Corophium volutator or Bathyporeia sarsi. The measured endpoints were mortality and sublethal effects, including the inability to reburrow after exposure, avoidance and immobilisation. Results show that sediment samples from the stations on each gradient closest to contaminant sources were toxic to nearly all test species. Samples from other stations only caused mortality in the tests with C. volutator.

“…These tests were conducted on shipboard during a cruise 1 wk earlier than all other sediment tests (Butler et al 1992). Some of the toxicity tests, which did not follow the contamination-toxicity trend, experienced difficulties in meeting quality assurance/quality control (QA/QC) requirements (Chapman et al 1992b). All tests showing the contamination-toxicity trend met the QMQC requirements.…”

ABSTRACT. This paper describes the pollution status of North Sea sediments, and is based on results of sediment testing conducted during the Bremerhaven Workshop designed to test various methods (chemical and biological) for assessing the status of North Sea waters, sediments and biota. Testing comprised 2 transects, one down current from an abandoned drilling site, and the other across the German Bight from the mouth of the Elbe northwest. Sediment methods focused on tox~clty testing, chemical analyses, and measures of in sltu benthic community structure Together these 3 methods comprise the Sediment Quality Triad. Using the Triad In a burden-of-evidence approach, ~t was determined that sediments nearest the Elbe are moderately polluted (pollution is defined as contamination. toxicity and benthic community alteration), and that sediments offshore and at Dogger Bank are unpolluted. Sediments nearest the drilllng site show evidence of relatively low level toxicity and benthic community alteration. Limited chemical measurements did not indicate contamination. Observed laboratory toxicity and alterations in benthic infauna community structure may be due to unmeasured toxic chemicals. Anticipated effects due to drilling were not observed and appear to have been amellorated by natural deposition of clean sediment. North Sea sediments away from point sources of pollution (e.g. coastal areas, drilling platforms) are expected to be unpolluted. Lesions in bottom fish in such offshore areas (e.g, the Dogger Bank) cannot be attributed to sediment pollution in these areas, but if they are truly indicative of anthropogenic pollution, could be due to other factorjs) such as exposure of plankton~c larvae to sea surface microlayer chemical contamination and toxicity. Integrative assessments such as the Triad are essential for adequately assessing the status of European marine ecosystems. Although relatively expensive, such complete studies determine and prioritise problem areas such that managers, regulators and the public have access to the best possible information for decisionmaking and resource allocation.

“…In addition, easy, inexpensive bacterial toxicity assays such as acute Microtox  tests, conducted on eluates from PSD resins after soil exposure could further indicate effects of bioavailable contaminants. Microtox  tests that evaluate acute toxicity by measuring a reduction in bioluminescence in a marine bacterium, have been used successfully as screening tests to determine the presence of contaminants available to elicit a toxic response (Tung et al 1991, Chapman et al 1992, Ross 1993, Ringwood et al 1997). GTI's principal toxicologist has extensive experience in conducting bioassays with invertebrates and microbes for both acute toxicity studies and bioaccumulation assays (Harkey 1993, Harkey et al 1994a,b,c, 1995, 1997a, KaneDriscoll et al 1997).…”

PUBLIC ABSTRACTThe drilling and operation of gas/petroleum exploratory wells and the operations of natural gas and petroleum production wells generate a number of waste materials that are usually stored and/or processed at the drilling/operations site. Contaminated soils result from drilling operations, production operations, and pipeline breaks or leaks where crude oil and petroleum products are released into the surrounding soil or sediments. In many cases, intrinsic biochemical remediation of these contaminated soils is either not effective or is too slow to be an acceptable approach. This project targeted petroleum-impacted soil and other wastes, such as soil contaminated by: accidental release of petroleum and natural gas-associated organic wastes from pipelines or during transport of crude oil or natural gas; production wastes (such as produced waters, and/or fuels or product gas). Our research evaluated the process designated Chemically-Accelerated Biotreatment (CAB) that can be applied to remediate contaminated matrices, either on-site or in situ. The Gas Technology Institute (GTI) had previously developed a form of CAB for the remediation of hydrocarbons and metals at Manufactured Gas Plant (MGP) sites and this research project expanded its application into Exploration and Production (E&P) sites. The CAB treatment was developed in this project using risk-based endpoints, a.k.a. environmentally acceptable endpoints (EAE) as the treatment goal. This goal was evaluated, compared, and correlated to traditional analytical methods (Gas Chromatography (GC), High Precision Liquid Chromatography (HPLC), or Gas Chromatography-Mass Spectrometry (CG-MS)). This project proved that CAB can be applied to remediate E&P contaminated soils to EAE, i.e. those concentrations of chemical contaminants in soil below which there is no adverse affect to human health or the environment. Conventional approaches to risk assessment to determine "how clean is clean" for soils undergoing remediation have been based on total contaminant concentrations in soil, as determined by laboratory extraction methods that use vigorous physical and chemical procedures. Numerous data collected from bioavailability studies in this study and others carried out by GTI and other organizations conducted on contaminated soils and sediments continue to show that not all contaminants are available to environmental receptors including man or ecologically forms. In short, there exist fractions of contaminants in soil that cannot be released from the soil matrix by normal means. These sequestered contaminant fractions should not be considered a risk to human health or the ii environment. This project focused on CAB technology to treat soil contaminants to these acceptable levels. Therefore, the primary objective of this project was to determine what these contaminant levels are and to reach or exceed cleanup standards using CAB. These determinations were demonstrated and verified using toxicity and chemical mobility tests. Based on GTI's experience with a fo...
