Novel approaches in macroinvertebrate biomonitoring
The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of how community measures are influenced by seasonal variability. Two separate …

Biomonitoring polybrominated diphenyl ethers in lactating women
… milk is a valuable biological specimen for biomonitoring lipid-soluble polybrominated diphenyl ethers (PBDEs). The goal of this project was to determine the levels of PBDEs in breast milk of lactating women from the Seacoast region of New Hampshire and to examine potential relationships …

Bilanzierung und Biomonitoring von Trifluoracetat und anderen Halogenacetaten
FCKW-Ersatzstoffe wie HFC 134a und die HCFC´s 123 und 124 sind teilhalogenierte Ethane. HFC 134a (1,1,1,2-Tetrafluorethan), zum Beispiel, hat eine atmosphärische Lebensdauer von etwa 15 Jahren. Es wird überwiegend in der Troposphäre bis zu 30% zu TFA abgebaut. TFA ist ökotoxikologisch von …

Biomonitoring an Impacted Stream Using Benthic Macroinvertebrates and Bioassays
… used a combination of benthic macroinvertebrate biomonitoring and single-species bioassays to monitor water quality in Wilson's Creek, Springfield, MO, for the 2-year period January 1993-December 1994. Wilson's Creek was potentially impacted by increased urbanization, agricultural run-off, and …

Hydrogeomorphic characterization and classification of Pacific Northwest mountain streams for biomonitoring
Biomonitoring using benthic macroinvertebrates has become the prevailing technique for assessing stream health in the United States. Because pre-disturbance biological conditions are rarely known, a reference site approach is often used to determine the extent of stream degradation. Ecoregions are …

Development and Application of Vegetation-Based Biomonitoring Criteria for Floodplain Wetlands
The condition and viability of floodplain wetlands in the Garrison Reach of the upper Missouri River is largely unknown. Due to the transitory nature of temporary and seasonal wetlands, wetland research in the region has focused primarily on semipermanent and permanent wetlands. As part of a …

Smart landscapes: revealing air pollution induced stress through in-situ biomonitoring
… the methodologies to build an on-site biomonitoring system that emphasizes the design intervention of landscape architecture to make the system widely practicable. This framework aims to supply the idea of the way landscape architects scientifically interpret urban dynamics and support …

Health Assessment of Artisanal Metal Work: Injury Patterns, Aerosol Exposures, and Biomonitoring
… environmental exposure assessment, and biomonitoring. Aim 1 analyzed First Reports of Injury (FROI) submitted to the Illinois Workers’ Compensation Commission from 2019 to 2023. Because sculptors lack a dedicated occupational classification, a surrogate group was identified using …

Development, Validation, and Evaluation of a Continuous, Real-time, Bivalve Biomonitoring System
… techniques was the foundation of the bivalve biomonitoring system. Current technology was used in developing the system to provide bivalve gape state data in a continuous real-time manner. A laboratory version of the system, including data collection and analysis hardware and software, was …

Studies of Benthic Macroinvertebrate Use for Biomonitoring of Mid-Atlantic Highland Streams
Research was conducted in three areas of water quality assessment. Long term ecological monitoring data from Shenandoah National Park (SNP) were analyzed and a protocol for data analysis was presented. Streams in SNP were found to be comparable to the best that can be found in the Blue Ridge …

Evaluating the Hazard of Land Applying Composted Diazinon Waste Using Earthworm Biomonitoring
A process for disposing of pesticide rinsewater generated from the rinsing of application equipment is being developed at Virginia Polytechnic Institute and State University. This process involves the sorption of pesticides onto an organic matrix followed by degradation in a composting environment. …

Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) as a Biomonitoring Tool
… that hair may serve as a safe and effective biomonitoring tissue for patients who receive GBCA injections. A mouse animal model was used to evaluate LA-ICP-MS as a biomonitoring tool in assessing cadmium exposure. Hair samples from mice that were part of a mechanistic toxicology study at the …

Biomonitoring of Stream Water Quality: Comparative Sensitivities of Macroinvertebrate Indices and Leaf Decomposition Rates
This study compared macroinvertebrate diversity indices with leaf decomposition rates in order to determine if both measures are sensitive to variation in water quality. Eight sites in the James River and its tributaries in southwest Missouri were sampled during summer 2001 and spring 2002 and …

Macroinvertebrate Biomonitoring Criteria and Community Composition in Seasonal Floodplain Wetlands of the Upper Missouri River
… macroinvertebrates were sampled to develop biomonitoring criteria for seasonal floodplain wetlands in the Garrison Reach of the Missouri River. Twenty-six seasonal wetlands were sampled in the summers of 2000-2001. Wetlands were designated as reference (n=6) or impaired (n=5) based on …
