Although the air we breathe is necessary for life, certain factors may make this same air detrimental to our health. For instance, a seemingly endless list of compounds can be toxic at certain concentrations, and inhaling such compounds may lead to damage in different parts of the body. To investigate the particular effects of inhaled toxicants, the NIEHS developed the Respiratory Toxicology Gr...

For many reasons, forensic toxicologists are being asked to determine and report their measurement uncertainty in blood alcohol analysis. While understood conceptually, the elements and computations involved in determining measurement uncertainty are generally foreign to most forensic toxicologists. Several established and well-documented methods are available to determine and report the uncert...

To analyze the implications for human health, the toxicologist requires four sets of data: the results of toxicity and other studies in animals; quantitative data on actual or potential human exposure; whatever information is available on effects of exposure in man; and the statistical extrapolations from the dose-response relationships in animals to the (usually) much lower levels of human exp...

Operant conditioning can contribute to the development of behavioral toxicology in many ways. Its techniques are useful in training animals in the various behaviors the toxicologist may wish to study. They make possible the sophisticated assessment of sensory functioning. Operant conditioners excel at using schedules of intermittent reinforcement to create the type of stable animal performance ...

The nasal cavity is susceptible to chemically induced injury as a result of exposure to inhaled irritants. Some responses of the nasal mucosa to inhaled toxicants are species specific. These species-related differences in response may be due to variations in structural, physiologic, and biochemical factors, such as gross nasal cavity structure, distribution of luminal epithelial cell population...
