Summary
Fluoride levels in Fiji
Area of Science:
- Environmental Science
- Public Health
- Analytical Chemistry
Background:
- The National Oral Health Survey (NOHS) in Fiji aims to assess oral health.
- Understanding fluoride content in drinking water is crucial for public health strategies.
- Fiji currently lacks a public water fluoridation program.
Purpose of the Study:
- To determine fluoride concentrations in drinking water sources across Fiji's divisions.
- To establish a baseline for potential water fluoridation initiatives.
- To inform caries prevention strategies.
Main Methods:
- Collected 223 drinking water samples from diverse sources (taps, wells, rivers, etc.) across Fiji.
- Analyzed fluoride content using a colorimetric assay with Zirconyl-SPADNS Reagent.
- Pre-treated samples with sodium arsenite to remove chlorine interference.
Main Results:
- All sampled drinking water had fluoride levels below the optimal 0.7 ppm for caries prevention.
- Mean fluoride concentration was 0.03 ± 0.04 ppm, with a range of 0.01–0.35 ppm.
- The Western Division showed the highest fluoride levels; Central Division's rural areas had the lowest.
Conclusions:
- Fiji's drinking water sources have insufficient fluoride for dental caries prevention.
- The findings provide essential baseline data for implementing water fluoridation in Fiji.
- This research supports the development and evaluation of public health interventions for oral health.

25.9K
A concentration cell is a type of a voltaic cell constructed by connecting two almost identical half-cells, both based on the same half-reaction and using the same electrode, differing only in the concentration of one redox species. A concentration cell's potential, therefore, is determined only by the concentration difference of the particular redox species.
Consider the following voltaic cell:

02:59Solution Concentration and Dilution
135.2K
The relative amount of a given solution component is known as its concentration. Often, though not always, a solution contains one component with a concentration that is significantly greater than that of all other components. This component is called the solvent and may be viewed as the medium in which the other components are dispersed or dissolved. Solutions in which water is the solvent are, of course, very common on our planet. A solution in which water is the solvent is called an aqueous...

01:23States of Water

Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

02:48Expressing Solution Concentration
69.2K
A solute is a component of a solution that is typically present at a much lower concentration than the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
Concentrations may be quantitatively assessed using a wide variety of measurement units, each convenient for particular applications. Molarity (M) is a useful concentration unit for many applications in chemistry.

01:13Stress Concentrations

The concept of stress concentration is crucial for understanding how materials respond under bending stresses, particularly when there are irregularities or discontinuities in the material's geometry. Normally, stress in a symmetric member subjected to pure bending is assumed to be uniformly distributed across the entire cross-section. However, this assumption does not hold when there are variations in the cross-sectional geometry or the presence of notches and holes.

Stress concentration is when stress intensifies near discontinuities such as holes or abrupt cross-sectional changes in a structural member. This localized stress can often surpass the average stress within the member. The stress distribution in flat bars, either with a circular hole or varying widths connected by fillets, can be determined experimentally using a photoelastic method. The results are based on ratios of geometric parameters like the ratio of the hole's radius to the smaller...
