Hexavalent chromium in water and effects
Hexavalent chromium (Cr(VI)), also known as chromic acid, is one of the most dangerous pollutants in water. It is widely used in industrial processes such as metallurgy, textile dyeing, and the production of paints and dyes. However, its presence in drinking water causes serious diseases due to its known toxic effects on health.
Chemical Characteristics and Sources
Chromium is a natural metal that occurs in many forms, the two most common being trivalent chromium (Cr(III)) and hexavalent chromium (Cr(VI)). Cr(III) is an essential trace element required in small amounts for the human body, while Cr(VI) is highly toxic and carcinogenic.
The main sources of hexavalent chromium in the environment come from industrial activities such as steel production, leather processing and the paint industry. The diffusion of these pollutants into the environment can occur through the discharge of industrial waste or leakage from landfills.
Impact on Health
The presence of hexavalent chromium in drinking water is extremely dangerous for human health. The main effects include:
- Cancer: Cr(VI) has been recognized as carcinogenic to humans by several health organizations, including the International Agency for Research on Cancer (IARC). Ingestion of water containing Cr(VI) has been linked to an increased risk of developing stomach and liver cancer.
- Skin Problems: Contact with Cr(VI) can cause dermatitis and skin ulcers. Workers exposed to high concentrations through their occupational activity are particularly susceptible to these conditions.
- Respiratory Problems: Inhaling particles containing hexavalent chromium can cause serious respiratory problems, such as asthma and respiratory infections.
- Genetic Effects: It has been shown that Cr(VI) can cause genetic damage, such as mutations in DNA, which can lead to serious health problems.
Environmental Impacts
Hexavalent chromium not only affects human health, but also has serious environmental impacts. Contamination of water with Cr(VI) can affect the fauna and flora of aquatic systems, as well as disrupt ecosystems.
Remediation and Cleaning Technologies
Addressing hexavalent chromium contamination is critical to protect public health and the environment. One of the most effective means of response is the use of advanced water filtration systems.
Camelot®, a pioneer in water purity, has developed specialised filters designed to remove hexavalent chromium from drinking water. Camelot® filters use technologies such as distillation and mineral enrichment, and are the Columbia D and Aqua Vie.
Conclusion
Water contamination with hexavalent chromium poses a serious threat to health and the environment. Its effects are widely recognized and include serious diseases, such as cancer and genetic damage. It is critical to take action to address this contamination, and Camelot’s® filtration technologies offer reliable solutions to remove hexavalent chromium from drinking water. By using Camelot’s® advanced water purification systems, we can ensure that the water we consume is clean and safe, thus protecting our health and the environment.
