Distilled water is a type of purified water that has been boiled to remove impurities. While this sounds beneficial, the distillation process also removes essential minerals from the water. As a result, distilled water is not recommended for drinking, and it may even have negative health impacts. One concern is that distilled water is highly aggressive and can leach undesirable compounds from the materials it contacts, including plastics, metals, and some organic substances. Therefore, it is recommended that distilled water be stored in glass containers to avoid consuming any leached compounds. However, some people choose to store distilled water in plastic containers, and the potential health risks of doing so are not yet fully understood.

What You'll Learn
Plastic fumes and health concerns
Plastic fumes are a health concern that can cause a range of issues, from short-lived irritation to long-term respiratory problems and even chronic illnesses like cancer. The health effects of inhaling plastic fumes vary depending on the length of exposure, type of plastic, type of gas released, and the process by which the fumes are produced. However, it is important to note that the combustion or burning of plastic releases a cocktail of chemicals, which are mostly toxic to humans.
The most common health symptoms from inhaling plastic fumes include irritation to the nose, throat, skin, and eyes. More severe symptoms can include neurological issues such as dizziness and confusion, which can be caused by exposure to styrene, butadiene, and acetone. Inhalation of plastic fumes can also lead to respiratory issues, with chemicals such as toluene causing respiratory problems and damaging the nervous system. Prolonged exposure to plastic fumes can also increase the risk of heart disease, aggravated asthma, skin irritations, headaches, nervous system damage, and organ damage, including to the kidneys and liver.
The burning of plastics releases toxic gases such as dioxins, furans, mercury, and polychlorinated biphenyls (BCPs) into the atmosphere. These toxins are harmful to humans and animals and can cause a range of health issues. For example, dioxins are potentially lethal persistent organic pollutants that can cause cancer, disrupt thyroid function, and cause respiratory issues. Phthalates in plastics are associated with fertility issues, neonatal impacts, allergies, and asthma.
To prevent health issues from inhaling plastic fumes, it is important to avoid burning plastic whenever possible. If plastic must be burned, it should be done in a well-ventilated area, and a mask or respirator should be worn to avoid inhaling the fumes. Employers should also monitor workplace air quality and implement safety controls to prevent exposure to plastic fumes. Additionally, plastic should be melted at the lowest possible temperature for the shortest amount of time, and residues from cleaning products should be avoided as they can create harmful fumes.

Plastic's impact on distilled water taste
Distilled water is a type of purified water that has been boiled to the point of evaporation and then condensed back into liquid form, leaving it devoid of impurities. While this may sound ideal, the term "impurities" covers a wide range of solids, including both contaminants and beneficial minerals. As a result, some argue that distilled water is not ideal for regular consumption.
The World Health Organization (WHO) claims that distilled water "might not be fully appropriate for consumption" as it can cause metals and other materials to leach from pipes and storage containers. This raises concerns about the potential impact of plastic storage containers on distilled water taste and safety.
Some people have expressed worries about the potential leaching of chemicals from plastic into distilled water, especially when heated or over time. These concerns are not unfounded, as certain plastics are known to leach harmful compounds. For example, plasticizers can leech from gaskets at high temperatures, imparting an unpleasant taste and aroma to the water.
However, others argue that food-grade plastic is generally safe for storing distilled water, and there are mixed reports of people noticing a plastic taste in their distilled water stored in plastic containers. Some recommend transferring distilled water to glass containers if there are concerns about plastic leaching, especially if the water is intended for use in a chemistry lab.
To conclude, while the impact of plastics on distilled water taste may vary depending on individual circumstances, it is advisable to exercise caution. Those concerned about potential plastic leaching can opt for alternative storage options such as glass or stainless steel containers, particularly if the distilled water is for regular consumption or sensitive applications.

Plastic's contamination of distilled water
Plastic contamination of water is a significant environmental concern today. Microplastics, or plastic debris smaller than 5mm and larger than 100 nanometers, have been found in over 90% of bottled water samples, with an average of 325 plastic particles per litre of water. One bottle of Nestle Pure Life contained levels as high as 10,000 particles per litre.
Distilled water is a type of purified water that has been boiled until it evaporates, and then condensed back into a liquid, leaving it devoid of impurities. However, this process also strips the water of beneficial minerals, and it does not discriminate between removing unwanted contaminants and beneficial minerals. Distilled water is also "highly aggressive" and can leach undesirable compounds from any material it comes into contact with, including plastics, metals, and some organic substances from pipes, coatings, storage tanks, and containers. This means that if you store distilled water in plastic containers, you may be at risk of consuming microplastics.
To avoid this, it is recommended to store distilled water in glass containers. Additionally, water filtration systems, such as reverse osmosis and ultrafiltration, can effectively remove microplastics from drinking water. These systems have micron ratings capable of filtering out contaminants smaller than 100 nanometers, ensuring that your drinking water is free of harmful microplastics.
While distilled water can help reduce plastic contamination compared to bottled water, it is not necessarily better than regular tap water, which may contain beneficial minerals. It is important to consider the source and quality of your tap water before opting for distilled water. In some cases, tap water may be a safer choice if it is known to be of good quality.

Plastic's degradation over time
Plastic degradation over time is a complex process that depends on various factors, including the type of plastic, environmental conditions, and the presence of microorganisms or enzymes. While plastic is known for its durability and longevity, its persistence in the environment has become a significant global concern.
The degradation of plastics can occur through physical or chemical processes. Physical degradation refers to changes in the bulk structure of plastics, such as cracking, embrittlement, and flaking. On the other hand, chemical degradation involves alterations at the molecular level, including bond cleavage and modifications in chemical groups. One critical aspect of plastic degradation is the role of microorganisms and enzymes. Certain microorganisms, such as bacteria and fungi, have the ability to break down plastics through enzymatic activities. For example, the bacterium Ideonella sakaiensis 201-F can efficiently degrade plastics like PET (polyethylene terephthalate) by secreting enzymes PETase and MHETase. These enzymes act synergistically to hydrolyze PET into its monomeric components, ethylene glycol (EG), and terephthalic acid (TPA).
The environmental conditions also play a crucial role in plastic degradation. Exposure to sunlight, temperature fluctuations, and physical stress can influence the degradation rate. For instance, a recent study found that polystyrene exposed to sunlight degrades much faster than previously estimated, highlighting the impact of UV radiation. Similarly, the estimated half-lives of common single-use plastics, such as LDPE plastic bags and HDPE milk bottles, vary significantly between landfill/compost/soil conditions and marine environments. In landfill/compost/soil, these plastics have estimated half-lives of 5 and 250 years, respectively, while in the marine environment, the half-lives shorten to 3.4 and 58 years, respectively.
Despite these degradation processes, plastic pollution remains a pressing issue. Plastic waste can persist in the environment for extended periods, breaking down into smaller and smaller pieces, known as microplastics and nanoplastics. These microscopic fragments can find their way into various ecosystems, from the peaks of mountains to the deepest oceans, impacting both ecological and human health. The presence of plastic in our water systems and food chains has raised concerns about its potential health risks, with estimates suggesting that humans ingest a credit card's worth of plastic per week.
To address the challenges posed by plastic degradation, global initiatives, such as the Basel Convention's Plastic Waste Partnership, aim to prevent, minimize, and manage plastic waste effectively. By uniting stakeholders from various sectors, the goal is to find sustainable solutions to reduce the leakage of plastic waste into the environment and reshape our relationship with this ubiquitous material.

Plastic's environmental impact
Plastic pollution has become ubiquitous, raising concerns about potential harm to humans and nature. Plastics do not break down in the environment, allowing them to accumulate in air, water, soil, and oceans. Research shows that plastic pollution may take between 100 to 1,000 years or more to decompose, depending on environmental conditions.
Once in the environment, plastic pollution can fragment into smaller pieces known as microplastics and nanoplastics. These microplastics have been found in every ecosystem on the planet, from the Antarctic tundra to tropical coral reefs. They have also been detected in all sources of water, types of food, placentas of pregnant people, and human stool ever tested. The ingestion or inhalation of microplastics and hazardous additives leaching out of plastic products can severely impact human health. Research indicates that more than 1,500 species in marine and terrestrial environments are known to ingest plastics, putting them at risk of suffocation or entanglement.
The production, use, and disposal of plastics have environmental and health effects at every stage of their lifecycle. Plastics are derived from fossil fuels, and the extraction process can release hundreds of toxins, causing damage to sensory organs, the respiratory system, nervous system, and gastrointestinal system. It can also impair organs, increase the likelihood of cancer, and cause neurological, reproductive, and developmental toxicity.
The use of plastic consumer goods exposes people to the toxic impacts of microplastics and chemicals. Only a small fraction of plastic waste is economically or technically viable to recycle, representing a mere 9% of all the plastic ever produced. As a result, plastic pollution poses a significant threat to the environment and human health, with potential impacts on ecosystems, food and water supplies, and human well-being.
