"Soluble inorganic arsenic (found in rocks and soil or dissolved in water) can have immediate and long-term toxic effects,” says Akanksha Mishra, a nutrition and wellness expert associated with myUpchar. “Among immediate effects, you can see gastrointestinal symptoms such as severe vomiting, abdominal pain, diarrhoea and disruption in blood circulation. Long-term exposure to arsenic from different sources can cause cancer, skin lesions, dementia, cardiovascular disease and diabetes. In early childhood, exposure has been linked to negative impacts on brain development,” adds Mishra.
