Arsenic

What is Arsenic?

Arsenic is a naturally occurring element found in soil, rocks, groundwater, and some foods. It exists in two main forms:

• Inorganic arsenic – the more toxic form, found in polluted groundwater, old pesticides, wood preservatives, and certain industrial processes.

• Organic arsenic – less toxic, mainly found in seafood like shellfish and seaweed.

Most people encounter small amounts of arsenic daily through food and water. But when exposure is elevated or prolonged, arsenic can become harmful. The urine arsenic test (µg/g creatinine) is a reliable way to assess recent arsenic exposure.

Common Sources of Exposure

• Water: wells or groundwater contaminated with inorganic arsenic

• Food: rice, grains, leafy vegetables, and seafood (especially shellfish and seaweed)

• Workplace: mining, smelting, glassmaking, or pesticide use

• Environment: regions with naturally high arsenic in soil or water

• Household: older pesticides or pressure-treated wood

Why Arsenic Exposure Matters

Arsenic is a toxic heavy metal that can affect nearly every organ system. Risks increase with long-term or high-level exposure:

• Skin problems: rashes, pigmentation changes, thickened skin

• Digestive upset: nausea, vomiting, abdominal pain, diarrhea

• Neurological symptoms: fatigue, brain fog, tingling in hands/feet, headaches

• Immune suppression: more frequent infections, slower recovery

• Organ stress: kidney and liver damage

• Cardiovascular harm: high blood pressure, vascular damage, heart disease

• Cancer: strong links to skin, bladder, and lung cancers from chronic inorganic arsenic exposure

Vulnerable groups include children, pregnant women, and individuals with impaired detoxification capacity.

Health Effects by Exposure

• Short-term (acute) exposure: nausea, vomiting, diarrhea, abdominal cramps, confusion, seizures (in severe cases)

• Chronic (long-term) exposure: skin lesions, anemia, immune dysfunction, cardiovascular disease, diabetes, developmental delays, and cancer risk

Because arsenic can accumulate in the body over time, even moderate exposure may contribute to long-term health problems.

Why Test for Arsenic?

A urine arsenic test is especially important if you:

• Live in an area with known arsenic contamination or rely on well water

• Eat diets high in rice, seafood, or grains

• Work in industries with metals, pesticides, or glass manufacturing

• Have chronic symptoms such as fatigue, brain fog, digestive issues, or skin changes

• Are undergoing a Heavy Metals or Total Tox Burden panel

• Want to track detox progress after reducing exposure

Key Takeaway & How to Lower Risk

Elevated arsenic in urine means recent or ongoing exposure—usually from contaminated water, food, or workplace contact. While low-level exposure is common, high or chronic exposure increases risks of immune dysfunction, organ stress, and cancer.

Steps to lower your risk:

• Drink filtered water (reverse osmosis or activated alumina systems are effective)

• Choose low-arsenic rice and limit seaweed or shellfish from unverified sources

• Avoid contact with arsenic-treated wood or old pesticides

• Support detox with hydration, a nutrient-rich diet, and medical guidance

If your test shows elevated arsenic, consult a healthcare provider experienced in environmental or heavy metal medicine for next steps.
