Fluoride Pollution in Groundwater:

1. Prolonged fluoride consumption:
- Prolonged fluoride consumption in higher concentrations in drinking water can immediately cause diarrhea and impaired nerve function. This is a serious health concern, especially in areas where fluoride pollution in groundwater is prevalent.

2. Biochar-mediated sand columns for defluoridation:
- Biochar-mediated sand columns can be used for defluoridation in hand pumps and tube wells. This method involves using biochar, which is a type of charcoal produced from organic materials, to remove fluoride from water. The biochar helps to adsorb fluoride ions, thereby reducing the fluoride concentration in the water.
Therefore, both statements are correct. Prolonged consumption of high concentrations of fluoride in drinking water can have immediate health effects, and biochar-mediated sand columns can be an effective method for defluoridation in groundwater sources such as hand pumps and tube wells.

  • Fluoride Remediation: A new study shows rice husk biochar removes fluoride from groundwater and reduces fluorosis. Fluoride is one of the pollutants in groundwater.
  • It is primarily caused by geological processes but is also contributed by anthropogenic activities across India. A team from Nalanda University investigated the potential of renewable biochar produced from rice husk biomass to absorb fluoride pollutants from groundwater.
  • Fluoride remediation using biochars showed significant removal at neutral pH. Biochar-mediated sand columns can be used for defluoridation in hand pumps and tube wells. Hence, statement 2 is correct.
    • Fluorosis: 9 It results from excessive fluoride intake from various sources, including food, water, air, and excessive use of toothpaste. 9 Prolonged fluoride consumption in higher concentrations in drinking water can cause dental fluorosis, skeletal fluorosis, kidney diseases, and arthritis. Hence, statement 1 is correct. 9 Dental fluorosis, or brown stains on the teeth caused by weakened enamel, is one of the most noticeable symptoms due to fluorosis.
