In recent times, there have been claims circulating about the safety of rainwater for drinking purposes. To ensure accurate information and curb misinformation, Prime 9ja Online conducted a fact-check to address two related claims: the belief that rainwater is too polluted for drinking and the notion that rainwater causes cough. Let's examine these claims individually.
CLAIM 1: Rainwater is now too polluted for drinking purposes due to the presence of per- and poly-fluoroalkyl substances (PFAS), according to a study by researchers from ETH Zurich and Stockholm University.
VERDICT: Partially true, but requires clarification.
ANALYSIS:
A recent study by researchers from ETH Zurich and Stockholm University has raised concerns about the presence of per- and poly-fluoroalkyl substances (PFAS) in rainwater and its potential impact on drinking water safety. However, the claim that rainwater is universally too polluted for drinking purposes requires further clarification.
According to the study highlighted in the press release from ETH Zurich, PFAS are human-made chemicals commonly used in the manufacturing of various consumer and industrial products. These substances, also known as "forever chemicals," have the ability to persist in the environment without decomposing. As a result of their widespread use, PFAS can be found in rainwater and snow, even in remote and isolated areas.
While it is true that PFAS has been associated with health risks and that guideline values for PFAS in drinking water and surface waterways have been lowered due to increased toxicity, it is important to note that the presence of PFAS in rainwater does not automatically render it unsafe for consumption in all situations.
The U.S. Centers for Disease Control and Prevention (CDC) acknowledges the potential health risks of PFAS, including liver damage, cancer, fertility issues, thyroid disease, and a higher risk of asthma. However, the health risks associated with PFAS exposure primarily stem from long-term ingestion of water or food contaminated with high levels of PFAS, rather than occasional exposure through rainwater consumption.
It is crucial to highlight that the quality of rainwater can vary depending on factors such as location, industrial activities, and environmental conditions. While rainwater collected in urban areas or regions with significant industrial pollution may carry a higher risk of contamination, rainwater collected in less polluted environments can still be suitable for certain non-potable uses, such as watering plants or household cleaning.
CLAIM 2: Rainwater causes cough.
VERDICT: False.
ANALYSIS:
There is no scientific evidence to support the claim that rainwater causes cough. Coughing can be caused by various factors such as respiratory infections, allergies, or irritants present in the environment. Rainwater itself does not possess properties that directly lead to coughing. However, if rainwater is contaminated with pollutants or allergens, it may indirectly contribute to respiratory issues in susceptible individuals. It is essential to focus on the quality of rainwater and potential contaminants rather than assuming a direct link between rainwater and coughing.
In our commitment to delivering factual news, it is crucial to rely on credible sources. For the fact-check, we referenced reputable sources such as ETH Zurich, the Centers for Disease Control and Prevention (CDC), and the Environmental Protection Agency (EPA). These sources provide valuable insights into the presence of PFAS in rainwater and their potential health risks.
It is important to stay informed and make decisions based on reliable information. While the presence of PFAS in rainwater is a valid concern, it does not automatically render all rainwater unsafe for consumption. The safety of rainwater depends on various factors, and individuals should refer to local guidelines and consult experts for accurate information regarding rainwater use.
