Biomonitoring Equivalents can be used for evaluation of biomonitoring data in a risk assessment context. Comparing biomonitoring data for a chemical with its Biomonitoring Equivalent provides a means for assessing whether population exposures to chemicals are within or above the levels considered safe by regulatory agencies.

A wide array of methods and instrumentation are used in workplace exposure monitoring. Direct-read instruments give immediate data, and include colorimetric indicators such as gas detector tubes, and electronic devices such as gas monitors and aerosol particle counters. In addition, samples may be collected and sent to a laboratory for slower ...
1,2-Cyclohexane dicarboxylic acid diisononyl ester (DINCH) is a mixture of organic compounds with the formula C 6 H 10 (CO 2 C 9 H 19) 2.DINCH is colorless oil. It is used as a plasticizer for the manufacture of flexible plastic articles in sensitive application areas such as toys, medical devices, and food packaging.
Aquatic biomonitoring is the science of inferring the ecological condition of rivers, lakes, streams, and wetlands by examining the organisms (fish, invertebrates, insects, plants, and algae) that live there. While aquatic biomonitoring is the most common form of biomonitoring, any ecosystem can be studied in this manner.
They are conducted according to published procedures to ensure consistency in data collection and analysis, and to compare findings to established metrics. Biosurveys typically use metrics such as species composition and richness (e.g. number of species, extent of pollution-tolerant species), and ecological factors (number of individuals ...
RIVPACS (River Invertebrate Prediction and Classification System) is an aquatic biomonitoring system for assessing water quality in freshwater rivers in the United Kingdom. It is based on the macroinvertebrate species (such as freshwater shrimp , freshwater sponges , worms, crayfish , aquatic snails , freshwater mussels , insects , and many ...
For example, hearing tests will be helpful when noise exposures are present, while tests assessing lung function or biomonitoring may be useful when airborne agents are present. It is also important to distinguish between tools using medical surveillance (measuring health effects) and hazard surveillance/exposure assessment (physical ...
In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues [1] to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention.
