Are Microplastics Present in Distilled Water Collected in a Glass Container?
When performing the process of distillation, distilled water is commonly considered to be a highly pure form of water, free from contaminants such as minerals and impurities. However, the question often arises regarding the presence of microplastics, particularly in cases where the distilled water is collected in a glass container and filtered using a charcoal filter. This article explores the likelihood of microplastics in distilled water and the steps to ensure purity.
Understanding Distillation as a Purification Method
Distilled Water is described as condensed steam from boiling water that has been filtered to remove impurities. The process involves boiling water to produce steam, which is then condensed back into liquid form, yielding water that is free from minerals, impurities, and other substances.
However, it is important to consider that while this process is effectual, there are subtleties to the practical application of distillation that can introduce contaminants such as microplastics into the water.
Risk Factors in Collecting Distilled Water in a Glass Container
Collecting distilled water in a glass container is a good practice as glass is an inert material that does not leach contaminants into the liquid. Nevertheless, other factors can influence the purity of the distilled water, especially when handling the equipment and the filters used.
The main risk of microplastics comes from the potential contamination introduced during the distillation process and subsequent storage. Here are a few scenarios to consider:
Container Material and Microplastics
Using glass containers significantly reduces the risk of microplastics, as glass does not interact with water in a way that could introduce harmful materials. However, microplastics can still enter the distilled water if any part of the system, such as the cleaning materials for equipment, is made of plastic.
Stainless Steel Equipment should be cleaned with non-plastic brushes or scrubbers to avoid introducing microplastics. Even the charcoal filter, if made of plastic, can potentially introduce contaminants into the water. Opting for ceramic or glass filters would be a safer choice in this scenario.
Charcoal Filter and Its Limitations
A charcoal filter is effective at removing chlorine and certain contaminants but is not designed to filter out microplastics. Charcoal filters themselves can be made from plastic or other materials that can introduce microplastics. Additionally, the filter's bag or sieve can also contain particles that could contaminate the water.
Environmental Contamination
Microplastics are present in the environment, and they can enter the distilled water through various means, including airborne particles or contamination from surfaces during handling. This is a significant source of potential contamination, even if all other measures are taken to ensure a clean system.
Ensuring the Absence of Microplastics
If you are concerned about the presence of microplastics in your distilled water, conducting specific tests is the most reliable method. These tests can involve:
Filtration using microfilter membranes to remove larger particles including microplastics.
Microscopy to visually inspect the water for the presence of microplastics.
Use of advanced analytical techniques such as infrared spectroscopy to identify the material composition of any particles found.
These tests should be performed by professionals to ensure accurate results.
Conclusion
While it is reasonable to believe that distilled water collected in a glass container with a proper charcoal filter should be free of impurities, including microplastics, the possibility of contamination cannot be entirely eliminated. Ensuring the purity of the water requires careful attention to the materials used in the distillation process and subsequent storage. Conducting specific tests for microplastics can provide peace of mind and ensure the quality of the water you consume.
