Industry:Biology; Chemistry
Type of environmental monitoring in which an individual's exposure to a substance is measured and evaluated.
Note: This is normally carried out using a personal sampler.
Industry:Biology; Chemistry
unit used to measure scent emission of people and objects; one olf is defined as the scent emission of an “average person”, a sitting adult that takes an average of 0.7 baths per day and whose skin has a total area of 1.8 m2; the scent emission of an object or person is measured by specially trained personnel comparing it to normed scents.
Note: The olf should not be confused with the of unit of scent immission (as opposed to emission), the decipol which also takes into account the ventilation system’s air volume flow.
Industry:Biology; Chemistry
Uptake of material into a cell by invagination of the plasma membrane and its internalization in a membrane-bounded vesicle.
Industry:Biology; Chemistry
US OSHA standard requiring all employers to inform employees of the hazard of substances in the workplace and the steps necessary to avoid harm.
Industry:Biology; Chemistry
Use of an artificial kidney to remove toxic compounds from the blood by passing it through a tube of semipermeable membrane.
Note: The tube is bathed in a dialysing solution to restore the normal chemical composition of the blood while permitting diffusion of toxic substances from the blood.
Industry:Biology; Chemistry
Variation of a quantity according to the law
A = Ae<sup>– λt</sup>
where A and A<sub>0</sub>are the values of the quantity being considered at time t and zero respectively, and λ is an appropriate constant.
Industry:Biology; Chemistry
Volume of fluid outside the cells but within the outer surface of an organism.
Industry:Biology; Chemistry
Volume of plasma or blood from which a substance is completely removed in a period of time under unstressed conditions.
