    \n
  • Short-term effects<\/b>: Coughing, sneezing, and wheezing are common in polluted areas.<\/span><\/li>\n
  • Long-term effects<\/b>: Continuous exposure leads to serious conditions like asthma, bronchitis, and lung cancer.<\/span><\/li>\n
  • Example<\/b>: Residents of industrial towns like Kanpur report high rates of asthma.<\/span><\/li>\n<\/ul>\n

    2. Cardiovascular Diseases<\/b><\/h3>\n
      \n
    • Polluted air increases blood pressure and causes inflammation in blood vessels.<\/span><\/li>\n
    • Long-term exposure raises the risk of heart attacks and strokes.<\/span><\/li>\n
    • Example<\/b>: Urban workers exposed to heavy traffic pollution show a higher incidence of heart disease.<\/span><\/li>\n<\/ul>\n\n\n\n\n\n

      Waterborne Diseases Due to Contaminated Water: UGC NET Key Points<\/b><\/h2>\n

      Water pollution occurs when harmful substances mix with water, making it unsafe for drinking, cooking, or bathing.<\/span><\/p>\n

      1. Stomach and Digestive Issues<\/b><\/h3>\n
        \n
      • Contaminated water often contains bacteria, viruses, and parasites.<\/span><\/li>\n
      • It can cause diarrhea, vomiting, and severe stomach pain.<\/span><\/li>\n
      • Example<\/b>: Villages near industrial areas face frequent outbreaks of waterborne illnesses.<\/span><\/li>\n<\/ul>\n

        2. <\/span>Skin Infections<\/b><\/h3>\n
          \n
        • Polluted water irritates the skin, leading to rashes and infections.<\/span><\/li>\n
        • Chemicals from industrial waste can worsen these conditions.<\/span><\/li>\n
        • Example<\/b>: Swimmers in polluted rivers often report itchy skin or fungal infections.<\/span><\/li>\n<\/ul>\n\n\n\n\n\n

          Neurological and Developmental Disorders from Toxic Waste: UGC NET<\/b><\/h2>\n

          Toxic waste from industries contains dangerous chemicals like lead, mercury, and pesticides, which harm the brain and nervous system.<\/span><\/p>\n

          1. <\/span>Neurological Disorders<\/b><\/h3>\n
            \n
          • Exposure to heavy metals can cause memory loss, tremors, and even brain damage.<\/span><\/li>\n
          • Pregnant women exposed to these pollutants risk developmental issues in their babies.<\/span><\/li>\n
          • Example<\/b>: Mercury poisoning in fish-eating communities has led to neurological disorders.<\/span><\/li>\n<\/ul>\n

            2.<\/span> Developmental Issues<\/b><\/h3>\n
              \n
            • Children exposed to polluted environments show slower cognitive development.<\/span><\/li>\n
            • Toxic waste can affect the mental and physical growth of kids.<\/span><\/li>\n
            • Example<\/b>: Areas near pesticide-heavy farms report developmental delays in children.<\/span><\/li>\n<\/ul>\n

              Hearing Impairment Caused by Noise Pollution: UGC NET Explained<\/b><\/h2>\n
