What is Arsenic? Arsenic Poisoning and Its Harms

Arsenic (As)

What is Arsenic?

Arsenic is a chemical element found in group 15 of the periodic table. Its symbol is "As," and its atomic number is 33. Naturally occurring, arsenic is typically found in various compounds and is often present in groundwater sources. It exists in both metallic and non-metallic forms and is commonly associated with the mineral arsenopyrite. In addition to natural occurrences, arsenic can also result from human activities such as agricultural pesticides, wood preservatives, and industrial waste. This versatile element has significant impacts on both human health and the environment.

Harmful Effects of Arsenic

Arsenic can accumulate in dangerous levels in water sources and certain foods, causing severe health issues with long-term exposure. Key harmful effects include:

• Cancer Risk: Increases the risk of skin, lung, and bladder cancer.
• Skin Disorders: Causes pigmentation changes and skin lesions.
• Respiratory Problems: Negatively affects lung health.
• Cardiovascular Diseases: Poses risks to the heart and blood vessels.
• Nervous System Disorders: Leads to memory loss and impaired nervous system functions.
• Reproductive Issues: Disrupts hormonal balance and can cause fertility problems.

To minimize these risks, it is essential to avoid consuming arsenic-contaminated water and food and to test water sources regularly.

Arsenic Poisoning

What is Arsenic Poisoning?
Arsenic poisoning occurs when excessive amounts of arsenic are ingested, leading to serious health complications. Symptoms include:

• Abdominal pain, nausea, and vomiting.
• Headaches and dizziness.
• Shortness of breath and coughing.
• Skin rashes and swelling.

Treatment Methods:

• Chelation Therapy: Uses specific drugs to remove arsenic from the body.
• Supportive Treatment: Manages symptoms and restores electrolyte balance.
• Hemodialysis: Removes arsenic in cases of impaired kidney function.

Forms of Arsenic

Arsenic exists in two primary forms:

• Inorganic Arsenic: Comes from natural sources and is commonly found in groundwater.
• Organic Arsenic: Absorbed through plants and animals.

Inorganic arsenic is more prevalent in environmental sources like soil and water and is significantly more toxic.

Preventative Measures Against Arsenic

• Water Quality Testing: Drinking water sources should be tested regularly.
• Agricultural Practices: Monitor the use of arsenic in pesticides and fertilizers.
• Public Awareness: Conduct campaigns to educate communities about the dangers of arsenic.
