What is a biomarker?
A biomarker (short for biological marker) is an objective measure that captures what is happening in a cell or an organism at a given moment. Biomarkers can serve as early warning systems for your health.
How to determine the technical description of a borehole?
in situ parameters that cannot be derived from highly disturbed drilling samples. A suite of geophysical log data, including deep-penetration methods, will more or less complete the technical description of a borehole, but geophysical logging is a specialized field best left to geophysical contractors or hydrogeological consultants.
What is a good borehole camera system?
The GeoVISION Deluxe (Product reference 6, Annex 7) is an example of a good borehole camera system. And if the water in a borehole is very turbid, back-scattering from the lighting system can swamp an image.
How can biomarkers be used in conjunction with environmental exposure modeling?
These are both examples of how biomarkers can be used in conjunction with environmental exposure modeling (questionnaire) to define dose response curves (correlating exposure (questionnaires) to internal dose (maternal and cord blood) and abnormal effect (decreased birth weight and birth length)).
