Arsenic

A toxic element found naturally in soil and water, and also from industrial and agricultural sources.

Can cause skin, bladder, lung, and kidney cancer. It may also affect the cardiovascular and nervous systems with long-term exposure.

Barium

A naturally occurring element often derived from industrial discharges and natural deposits.

Can lead to increased blood pressure, heart and nervous system problems, and long- term exposure may cause kidney damage.

Cobalt

A naturally occurring metal used in industrial processes, sometimes found in water due to mining runoff.

Long-term exposure can lead to heart problems, lung disease, and thyroid issues. It may also affect fertility and increase cancer risks.

Chromium

A metal found in water from industrial waste, especially from metal plating and textile production.

Can cause skin irritation and damage to the liver and kidneys. Long-term exposure is linked to lung and nasal cancer.

Lithium

Naturally occurring element used in batteries and medications.

In high doses, may affect kidney function and thyroid regulation.

Nitrate

Commonly found in water due to agricultural runoff, sewage, and industrial waste.

Can cause methemoglobinemia, or "blue baby syndrome," in infants and may increase the risk of cancer and thyroid problems with prolonged exposure.

Selenium

An essential trace element that can become toxic in high concentrations.

High exposure can cause hair loss, gastrointestinal issues, and nervous system problems.

Sulfate

A naturally occurring mineral found in water from soil leaching, rocks, and industrial processes.

High sulfate levels can cause gastrointestinal discomfort, including diarrhea, especially in infants and sensitive populations.

Toluene

A solvent used in chemical manufacturing and found in water through industrial discharge.

Uranium

A radioactive element naturally present in soil and groundwater.

Can increase the risk of kidney damage and cancer, especially when ingested over time.
