**Austin Air: Texas Sunscreen Hiding Baby Harm?**
By Franklin Everett ShawThe carefree days of summer in Austin, Texas, often involve splashing in Barton Springs or enjoying Zilker Park. But beneath the surface of sun-drenched fun, a potential concern lurks, especially for parents of infants and young children living near Mopac, I-35, or Highway 183: the potential impact of sunscreen chemicals on our water supply and, consequently, on developmental health. It’s time to ditch the blissful ignorance and dive into the science, the risks, and, most importantly, the solutions.
Oxybenzone, a common ingredient in chemical sunscreens, is an endocrine disruptor. This means it can interfere with the body’s hormones, potentially leading to developmental problems, especially in young children. Studies have linked oxybenzone exposure to altered birth weights and other adverse health effects. The problem? When we shower after applying sunscreen, or when kids play in the water, these chemicals wash off and enter our wastewater system. While Austin’s water treatment plants do a decent job, they aren’t designed to completely remove these emerging contaminants.
So, what happens to that oxybenzone? It can end up in our rivers and lakes, and potentially even leach into the groundwater, impacting the very water we drink and use for recreation. This is particularly concerning for families living near major roadways. Runoff from these areas, already burdened with pollutants, can exacerbate the problem, carrying sunscreen chemicals directly into nearby waterways during rain events. Think about the runoff from a summer downpour near the intersection of Mopac and Bee Caves Road – that water is heading somewhere, and it could be carrying oxybenzone with it.
The challenge is that current water quality monitoring in Austin doesn’t routinely test for oxybenzone and similar sunscreen chemicals. We’re essentially flying blind, unaware of the true extent of the problem. This lack of data makes it difficult to assess the actual risk to public health, particularly for vulnerable populations like infants and young children.
But don’t despair! There are actionable steps we can take, starting today.
First, choose safer sunscreen alternatives. Look for mineral-based sunscreens containing zinc oxide or titanium dioxide. These ingredients are considered safer for both human health and the environment. They work by creating a physical barrier on the skin, rather than being absorbed like chemical sunscreens.
- Read labels carefully. Don’t be fooled by marketing claims. Look for “zinc oxide” or “titanium dioxide” as the active ingredients.
- Check for “non-nano” particles. Nano-sized particles can potentially penetrate the skin and cause harm.
- Consider brands readily available in Austin pharmacies. Badger Balm, Thinkbaby, and Blue Lizard are generally good choices and can be found at stores like Wheatsville Co-op, Central Market, and even some HEB locations.
Second, reduce your sunscreen usage when possible. Seek shade, wear protective clothing, and avoid peak sun hours (10 AM to 4 PM). This is especially important for infants, who should be kept out of direct sunlight as much as possible.
Third, advocate for improved water quality monitoring. Contact your Austin City Council member and urge them to support initiatives to test for oxybenzone and other emerging contaminants in our water supply. Demand transparency and public access to this data. The city needs to understand the scope of the problem before it can effectively address it.
Fourth, be mindful of where you apply and rinse off sunscreen. Avoid applying sunscreen directly near storm drains or waterways. When showering, consider using a drain filter to capture some of the sunscreen residue. While not a perfect solution, it’s a small step that can make a difference.
Fifth, educate others. Share this information with your friends, family, and neighbors. The more people who are aware of the issue, the more likely we are to see meaningful change. Talk to your pediatrician about safer sunscreen options for your children.
A common pitfall is assuming that all sunscreens are created equal. They are not. Many popular brands contain harmful chemicals that can pose risks to your health and the environment. Another mistake is relying solely on sunscreen for sun protection. Sunscreen should be used as a last resort, after seeking shade and wearing protective clothing.
Another challenge is the lack of clear and consistent labeling on sunscreen products. It can be difficult to decipher the ingredients and understand the potential risks. This is where consumer education and advocacy come in. We need to demand better labeling and more transparency from sunscreen manufacturers.
Let’s be honest, switching to mineral-based sunscreens can be a bit of an adjustment. They can sometimes be thicker and leave a white cast on the skin. However, the benefits far outweigh the inconvenience. There are now many mineral sunscreens that are lightweight, easy to apply, and don’t leave a noticeable residue. Experiment with different brands to find one that works for you.
This isn’t about fear-mongering; it’s about informed decision-making. As residents of Austin, particularly those raising young families near busy roadways, we have a responsibility to protect our water supply and the health of our children. By choosing safer sunscreens, reducing our usage, and advocating for improved water quality monitoring, we can make a real difference. Let’s work together to ensure that our city remains a healthy and vibrant place for generations to come. The future of our children, and the health of our environment, depends on it.
