At Reliable Testing Laboratory, we understand the importance of safe, clean water for your health and well-being. While water is essential for life, it can also be a hidden source of contamination—particularly from harmful heavy metals like lead, mercury, arsenic, and cadmium. These metals, often invisible to the naked eye, can pose serious long-term health risks when present in drinking water.
As a material testing laboratory in Dubai, we specialize in identifying these hidden contaminants to ensure the water you consume is safe and free from harmful substances.
Top 5 Heavy Metals That Typically Exist in Water
Heavy metals are naturally occurring elements that can find their way into water sources through various environmental and industrial processes. Some metals are present in trace amounts in natural water, while others are introduced through pollution. Below are some of the most common heavy metals found in water:
Lead (Pb)
Lead is one of the most concerning heavy metals in drinking water. It often enters water through the corrosion of old plumbing systems, particularly in homes with lead pipes or fixtures. Even small amounts of lead can be harmful, especially to children, affecting their nervous system and development.
Mercury (Hg)
Mercury can contaminate water through industrial discharges, mining activities, and the improper disposal of mercury-containing products. It can accumulate in fish and other aquatic organisms, posing risks to humans when consumed. Mercury exposure can lead to neurological damage, kidney issues, and developmental problems.
Arsenic (As)
Arsenic naturally occurs in the Earth’s crust and can leach into groundwater, especially in areas with high geological arsenic concentrations. It can also come from industrial activities such as mining and the use of pesticides. Long-term exposure to arsenic is linked to skin, lung, and bladder cancer, as well as cardiovascular and respiratory problems.
Cadmium (Cd)
Cadmium is often released into water through industrial processes such as metal plating, mining, and the burning of fossil fuels. It can also enter water through agricultural runoff from fertilizers and pesticides. Chronic exposure to cadmium can lead to kidney damage, weakened bones, and high blood pressure.
Chromium (Cr)
Chromium, particularly hexavalent chromium (Cr VI), is a highly toxic form that can enter water through industrial activities such as steel production, leather tanning, and the disposal of waste. It can cause skin ulcers and respiratory problems and is classified as a carcinogen, increasing the risk of lung cancer.
Copper (Cu)
Copper is an essential trace element but can be harmful in higher concentrations. It typically enters water through corrosion of copper pipes and plumbing fixtures, especially in areas with acidic or soft water. High levels of copper can cause gastrointestinal distress, liver damage, and, in extreme cases, kidney failure.

How to Test for Heavy Metals in Water
At Reliable Testing Laboratory, we have introduced effective methods for heavy metal analysis. Inductively Coupled Plasma (ICP) testing is a highly effective and precise method for detecting and quantifying trace levels of heavy metals in various environmental and industrial samples, including water, soil, air, food, and industrial materials.
The process involves introducing the sample into a high-temperature plasma, where it is atomized and ionized. The resulting ions are then analyzed using optical emission spectroscopy (OES) or mass spectrometry (MS) to identify and measure the concentrations of heavy metals such as mercury, lead, chromium, cadmium, arsenic, copper, nickel, and zinc. This method is particularly valuable due to its ability to detect even the smallest concentrations of metals, which is crucial for assessing health risks and environmental contamination.
ICP testing plays a critical role in ensuring safe drinking water, maintaining industrial quality control, and supporting environmental research and monitoring. It also provides valuable data for developing effective remediation strategies and complying with safety regulations, making it an essential tool in protecting public health and the environment.
Understanding the Harmful Effects of Heavy Metals on Human Health
Heavy metals can have severe harmful effects on the human body, even at low concentrations. These metals, including lead, mercury, arsenic, cadmium, and chromium, can accumulate over time, leading to both acute and chronic toxicity. They disrupt normal cellular functions by displacing essential metals from their natural binding sites, causing cellular malfunction and damage.
For example, lead exposure can affect the nervous system, leading to developmental issues in children and cognitive decline in adults. Mercury can damage the kidneys and nervous system, while arsenic exposure is linked to skin lesions, lung cancer, and cardiovascular diseases.
Cadmium is toxic to the kidneys and bones, and chromium, particularly hexavalent chromium, is a known carcinogen that can cause lung cancer. Prolonged exposure to these heavy metals can result in organ damage, immune system dysfunction, and increased susceptibility to various chronic diseases, highlighting the importance of monitoring and controlling heavy metal levels in our environment and food.

FAQ
1. Does boiling water remove heavy metals?
No, boiling water does not remove heavy metals. While boiling can eliminate certain bacteria and pathogens, it cannot reduce or eliminate heavy metals such as lead, mercury, arsenic, or cadmium. In fact, boiling may concentrate these metals if they are present, as water evaporates during the process. To remove heavy metals, advanced filtration systems like reverse osmosis or ion exchange are recommended.
2. How does someone get heavy metal poisoning?
Heavy metal poisoning can occur through various sources, including contaminated drinking water, polluted air, and exposure to industrial or agricultural materials. Consuming foods grown in contaminated soil or seafood with high levels of mercury is another common cause. Additionally, occupational exposure in industries such as mining, construction, or manufacturing can increase the risk of heavy metal poisoning.
3. What are the symptoms of heavy metal poisoning?
The symptoms of heavy metal poisoning vary depending on the type and level of exposure. Common symptoms include:
- Neurological issues such as memory loss, confusion, and headaches.
- Fatigue, weakness, and muscle pain.
- Digestive problems, including nausea, vomiting, and abdominal pain.
- Kidney damage and abnormal urinary output.
- Skin changes, such as discoloration or lesions.
- Long-term exposure may lead to chronic conditions like cancer, organ damage, or developmental issues in children.
4. How can I reduce my risk of heavy metal poisoning?
Test soil and water regularly, especially if you grow food or rely on a private water source.
