Data on assessing fluoride risk in bottled waters in Iran

The general goal of this data was to determine the concentration of fluoride and assess its risk in waters bottled in Iran. Seventy-one samples of different brands of bottled water were collected. Then, the fluoride concentration was measured through standard method for water and wastewater experiments. The non-carcinogenicity risk of fluoride for different groups of infants, children, teenagers, and adults was calculated by proper formula. The data presented here indicated that the mean concentration of fluoride in bottled waters was 0.272 mg/L, which is lower than the minimum world health organization (WHO) guideline. Further, the mean hazard quotient (HQ) values for fluoride across the groups of infants, children, teenagers, and adults with respective values of 0.0363, 0.2568, 0.1813, and 0.1452 were observed in 0, 1, 1, and 0 cases of HQ>1. Generally, in most of the tested brands, HQ value was less than 1, and this value was above 1 in only one brand of bottled water.


Specifications
Bottled water quality and risk assessment More specific subject area Bottled water fluoride Type of data Tables  How data was acquired Bottled water brands tested were obtained from the Iranian Bottled water association. The fluoride concentration of the samples was measured using an Ion Chromatography No. 4110 in accordance with the method described in "Standard methods: For the examination water and wastewater, 22nd edn" [1][2][3][4][5][6][7][8]. Data format Raw, Analyzed Experimental factors 71 different brands of high-consumption bottled water in Iran were randomly selected Experimental features Determine the concentration level of fluoride Data source location Iran Data accessibility The data are available with this article

Value of the data
The data analysis indicated that HQ value was less than one in many of the studied brands.
Therefore, the possibility of incidence of non-carcinogenicity effects resulting from fluoride consumption in bottled waters was very low, and presence of fluoride in the bottled waters does not pose any risk to the consumers.
This data can be useful to consumers of bottled water in terms of quality of bottled water help to consumers in areas with low concentrations of fluoride in drinking water, food and beverages with high levels of fluoride use.
Since water deficit exists in some regions of Iran, thus people use bottled waters. As the mean concentration of fluoride is lower than the standard value in many of the measured water samples, thus it is suggested that fluoride-containing toothpastes be used in these regions.
This data can be used by researchers and managers of bottled waters production industries to evaluate the effects of fluoride in bottled waters and improve the quality of bottled waters.

Data
The parameters used in calculation of fluoride risk assessment in the consumed bottled waters are provided in Table 1. Fluoride concentration and fluoride estimated daily intake (EDI) and the values of hazard quotient (HQ) for the four population groups consuming bottled waters are shown in Table 2. Table 1 Parameters used in the present study data for health exposure assessment in drinking water [35].

Measuring the fluoride concentration in bottled waters
Seventy one samples of different brands of bottled waters were chosen randomly, and then the fluoride concentration of water samples was determined by Ion Chromatography No. 4110 based on the method mentioned in the book of standard methods for water and wastewater experiments .

Assessing fluoride risk
In this data, the non-carcinogenicity risk of fluoride resulting from consuming bottled waters was calculated across different age groups. First, the parameters of classification of age groups, body weight, and amount of water consumption were chosen based on the study by Yousefi et al., such that the age groups were categorized into the groups of infants (younger than two years old), children (2-6 years old), teenagers (6-16 years old) and adults (above 16 years of age), and the mean water consumption across the age groups was selected as 0.08, 0.85, 2, and 2.5 L/day, respectively [25]. The body weight across the different age groups of newborns, children, teenagers, and adults was chosen as 10, 15, 50, and 75 kg, respectively.
Then, estimation of data consumption of fluoride across the different brands of bottled waters was performed by Eq. (1) [25,[30][31][32][33][34]: EDI: Estimated daily intake of fluoride (mg/kg d), C f : The fluoride concentration in the bottled waters (mg/kg), C d : The mean daily consumption of drinking water (L/d), B w : Body weight (kg). Furthermore, the hazard quotient (HQ) was calculated by Eq. (2) to predict the non-carcinogenicity risk of exposure to fluoride: In this equation, HQ represents the hazard quotient (to show the non-carcinogenicity effects), CDI is the chronic daily intake (mg/kg d), and RFD is the reference dose (mg/kg.d). The reference dose for fluoride is 0.06 mg/kg d.
HQ value larger than 1 suggests probability of incidence of non-carcinogenicity effects in the exposed population. On the other hand, HQ o1 shows absence of probability of incidence of noncarcinogenicity effects in the exposed population.
