“…Fluoride's effects on human health, however, are not immediate but chronic, so long-term exposures to high doses of fluoride are obligatory (Jia et al 2019). The key routes of human ingestion of fluoride are fluoride-containing groundwater used for drinking purposes, food compounds, and toothpaste (Das et al 2020). Fluoride can be absorbed from the gastrointestinal tract after ingestion, following inhalation, and through the skin.…”

Groundwater fluoride contamination in some parts of the study region was long recognized as a water quality issue. The results of WQI showed that 85% and 15% of sampling sites fall within the class of “good” and “poor” quality, respectively. Non-carcinogenic health risk (NCHR) assessment (using Hazard quotient (HQ)), and sensitivity analysis for three age groups were also carried out using the Monte Carlo simulation technique. The estimated levels of HQoral were greater in magnitude than those estimated from HQdermal, thus the main source for fluoride toxicity is oral ingestion. Amongst the three age groups studied, children >female >male were found to be more prone to NCHR with HQoral ranging from (0.13-5.45), (0.07-2.97), and (0.06-2.51), respectively. Sensitivity analyses indicated that fluoride concentration, ingestion rate, shower exposure time, and fractional skin contact with water were the most relevant variables in the model to reduce the potential health effect.
