DNA adducts in biomonitoring

Toxicology Letters, 1995
The types of occupational groups studied by postlabelling include foundry, coke oven and aluminium workers, roofers, garage and terminal workers, car mechanics and chimney sweeps. There does not seem to be a direct relationship between the exposure and adduct levels.

Biomonitoring Equivalents for glyphosate

Regulatory Toxicology and Pharmacology, 2023
One of the most widely used herbicides worldwide, glyphosate is registered for use in many agricultural and non-agricultural settings. Accordingly, regulatory authorities develop toxicology reference values (TRVs) to conduct risk assessments for potential exposures. Exposures to glyphosate are typically biomonitored via measures of glyphosate in urine.

Biomonitoring Equivalents for deltamethrin

Regulatory Toxicology and Pharmacology, 2011
Measured concentrations of chemicals in blood or urine in biomonitoring studies provide an integrated reflection of exposures to chemicals via multiple routes and pathways. The potential significance of the measured concentrations of chemicals in the context of existing toxicology data and risk assessments can be assessed if chemical-specific ...

Human biomonitoring of antimony

International Archives of Occupational and Environmental Health, 1998
The aim of the study was to test the suitability of 24-h urine, blood, and scalp-hair samples as surrogates for the determination of internal exposure to antimony in case of a strongly elevated soil contamination with antimony.The bio-monitoring was performed using graphite-furnace atomic absorption spectrometry.

Biomonitoring Equivalents for cyanide

Regulatory Toxicology and Pharmacology, 2018
Exposure to cyanide is widespread in human populations due to a variety of natural and anthropogenic sources. The potential health risks of excess cyanide exposure are dose-dependent and include effects on the thyroid, the male reproductive system, developmental effects, neuropathies and death.

Biomonitoring Equivalents for benzene

Regulatory Toxicology and Pharmacology, 2012
Biomonitoring Equivalents (BEs) are defined as the concentration or range of concentrations of a chemical or its metabolite in a biological medium (blood, urine, or other medium) that is consistent with an existing health-based exposure guideline such as a reference dose (RfD) or tolerable daily intake (TDI).

Biomonitoring Equivalents for selenium

Regulatory Toxicology and Pharmacology, 2014
Selenium is an essential nutrient for human health with a narrow range between essentiality and toxicity. Selenium is incorporated into several proteins that perform important functions in the body. With insufficient selenium intake, the most notable effect is Keshan disease, an endemic cardiomyopathy in children.

Biomonitoring Equivalents for triclosan

Regulatory Toxicology and Pharmacology, 2010
Recent efforts worldwide have resulted in a growing database of measured concentrations of chemicals in blood and urine samples taken from the general population. However, few tools exist to assist in the interpretation of the measured values in a health risk context.

Biomonitoring of arylamines and nitroarenes

Biomarkers, 2002
Arylamines and nitroarenes are very important intermediates in the industrial manufacture of dyes, pesticides and plastics, and are significant environmental pollutants. The metabolic steps of N-oxidation and nitroreduction to yield N-hydroxyarylamines are crucial for the toxic properties of arylamines and nitroarenes.

Biomonitoring

2023
Biomonitoring refers to the systematic measurement of compounds and/or detection of cell or cell molecules alterations in living organisms with the purpose of identifying or assessing potential hazardous exposure and effects to chemicals or other hazardous agents.
