Data from the literature were used to assign statistical distributions to swimming pool chloroform concentrations, frequency and duration of swimming, showering and bathing, and average tap water consumption.
Both Durda and Preziosi [11] and Schneider et al. [13] consider administrated concentrations, administration route, frequency and duration of exposure as "must" criteria.
Administrated concentrations, concentration control analysis, administration route, frequency and duration of exposure, and information of the dosing type are aspects related to the "dosing system" that the four evaluation methods all together consider as important.
Although the presence of trace levels of these pesticides in food is considered as an indication that contamination has occurred, the risk of adverse health effects also depends on their concentration, frequency of contact and duration of exposure (Jiang et al., 2005).
There is a general understanding that the fluoride compound, concentration, frequency of use, duration of exposure, and method of delivery can influence fluoride efficacy.
Hazard assurance that a chemical or nanoparticle can show up in the tissue of the host and any other living organism is usually dependent upon the frequency, concentration, and duration of exposure of the materials due to factors including the magnitude, extent, and duration to cause toxic side effects.
Additional factors related to potential respiratory symptoms are the frequency and duration of exposure, the concentration of ash in the air and the respirable ash fraction; the proportion of ash with less than 10 µm diameter, known as PM10.
The effects of potential range, frequency and duration time of SWPPs and H2SO4 concentration on the construction of DG were systematically investigated.
The amount of PCE contributed by inhalation is a function of the temperature, frequency and duration of baths and showers, and the concentration of PCE in the bathtub/shower stall air.
In Siamese fighting fish (Betta splendens), the SSRI fluoxetine has been demonstrated to reduce both frequency and duration of aggressive displays across a variety of concentration exposure procedures.
