The study of the exposome requires a multi-disciplinary approach that combines advances in exposure assessment, bioinformatics, and systems biology. As such, researchers have developed a range of key methodologies to measure and analyze the exposome – from exposure assessment techniques, analytical tools, to computational approaches.
Exposure science is the study of the contact between humans (and other organisms) and harmful agents within their environment – whether it be chemical, physical, biological, behavioural or mental stressors – with the aim of identifying the causes and preventions of the adverse health effects they result in. [1] [2] This can include exposure within the home, workplace, outdoors or any other ...
Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. [1] It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. [ 1 ]
A very low dose of a chemical agent may trigger from an organism the opposite response to a very high dose.. Radiation hormesis proposes that radiation exposure comparable to and just above the natural background level of radiation is not harmful but beneficial, while accepting that much higher levels of radiation are hazardous.
According to the health department, one of the biggest sources of lead exposure for New York City children is lead paint, which can flake and crumble onto floors, especially at friction points like door and window frames. It’s an issue in many cities and towns with older housing stock.
Inhalation is a major route of exposure that occurs when an individual breathes in polluted air which enters the respiratory tract. Identification of the pollutant uptake by the respiratory system can determine how the resulting exposure contributes to the dose. In this way, the mechanism of pollutant uptake by the respiratory system can be ...
Few things will put a damper on your vacation or holiday faster than food poisoning. The intense stomach pain, rushing to the toilet and feeling relegated to bed keeps just about everyone out of ...
In the U.S., the biggest polluters are often concentrated in underserved, mostly minority communities.
