A team of researchers from the Desert Research Institute, U.S. Geological Survey (USGS), the University of Nevada, Reno and Portland State University has discovered contamination in the snow across the Rocky Mountains.
The researchers analyzed seasonal snowpack samples from 2018 that were collected across 49 sites around the Rocky Mountains to determine levels of metals such as mercury, zinc, cadmium and antimony.
As part of the study, the team looked at metals found in natural dust as well as metals found in dust from human activities, such as mining. By investigating the metal contaminant levels in both natural dust and human-caused dust, the researchers connected particular metal contamination levels to human activities.
The study, published in the journal Environmental Pollution, revealed higher metal contamination levels in snow of the northern Rocky Mountains and sites in Montana, Idaho and northern Wyoming.
They then compared and confirmed their findings using the data from the National Atmospheric Deposition Program, which monitored the levels of mercury and calcium in precipitation from 2009 to 2018.

“The snow samples showed us that contamination is higher in the northern Rockies, and that was really interesting,” Monica Arienzo, associate research professor of hydrology at Desert Research Institute, said in a statement. “Looking at mercury contamination over time helped us say that 2018 is not just a fluke. When you start to see these trends that are consistent between different records, it makes you feel more confident that something’s really happening here.”
The study determined that the cadmium, mercury, antimony and zinc found at higher levels in the northern sites were likely from human activity, particularly mining and smelting.
“Our idea is that the dust from current and historical mining sites gets carried up into the mountains and deposited across our study sites,” Arienzo said. “This study shows the importance of continued scientific monitoring efforts, like the long-term USGS datasets we used here, as well as mitigation of current and historical mining sites.”
Based on the results of this research, the study authors recommended that officials and industry experts should focus on monitoring and mitigating contamination from active mining and smelting sites, while former sites should be remediated for contamination. Limiting further contamination and cleaning up existing pollution is especially important, as more than 60 million people rely on the water runoff from Rocky Mountain snow, the study authors wrote.
Moving forward, the research team will compare these results to ongoing tree ring research in the area to get a more comprehensive look at how pollutants like mercury can spread and affect the environment.

Have you ever seen those ‘everything shower’ videos trying to convince you to use 12+ products on your skin and hair? Including plastic poufs destined for landfill in 2 months time?
All you really need is a bar of soap, shampoo/conditioner, safety razor, and something natural to lather with. Enter Casamera, a sustainable brand who creates konjac sponges for face and body (aka all-natural shower sponges).
But what exactly is a konjac sponge? And are they all created equal? Here’s everything you need to know so you can ditch plastic poufs for good.
What Is a Konjac Sponge?
A konjac sponge is a natural skin exfoliant made from the konjac plant, a root vegetable. To make konjac sponges, the konjac tubers are harvested and fiber (glucomannan) is extracted from the root.
The fiber is mixed with water and various other natural ingredients to form a gel-like mixture. This mixture is poured into molds to create the desired shape and size. It’s then steamed to solidify and stabilize the structure.
Casamera makes all-natural shower sponges that include konjac powder as one of the four natural ingredients it takes to make one. Their scrubbers come in a variety of infusions, such as charcoal (best for oily/acne-prone skin), matcha, volcanic mud, peppermint, and walnut.
But not all konjac sponges are the same: Casamera’s dual-sided design has one soft side and one exfoliating side (powered by natural walnut shells), making it suitable for both face and body.
Most conventional konjac sponges are for facial skincare only, making Casamera’s a perfect replacement for plastic poufs. The ergonomic handle fits perfectly in your hand, and you can easily hang it up to dry after use.
Konjac Sponge Benefits
The best known benefits of using a konjac sponge are cleansing and gently exfoliating skin. It’s extremely gentle, so it can help unclog pores, especially helpful to those with oily or acne-prone skin.
Casamera’s sponges are also 100% compostable, unlike plastic poufs destined for landfills. It’s also dual sided: The honeycomb side is perfect for washing up whereas the other side exfoliates for deep cleaning.
Plastic poufs can also smell moldy after just a week. Casamera’s scrubbers don’t have that problem because they’re antimicrobial and fast-drying. Which means less replacements and more money saving!
You’re also not scrubbing microplastics onto your body and down the drain. Casamera’s sponges are plastic-free, even down to their low-waste shipping materials. Plus they plant trees to offset their carbon footprint from manufacturing and shipping!
There’s three different sizes: The OG, the XL and the mini. The mini is great for the face, OG works as an ideal body scrubber, and XL is perfect for smothering your body (and backside) in soapy suds.
How to Use a Konjac Sponge (Step-by-Step)
To use Casamera’s scrubbers, here’s a simple step by step routine that’s easy to remember:
- Presoak the scrubber with water
- Apply body wash to it (I love Plaine Products refillable body wash)
- Scrub away!
- Rinse it out (make sure there’s no suds or water left)
- Hang it dry (ideally in a well-ventilated area)
How Long Do Konjac Sponges Last?
If properly maintained, a konjac sponge can last 2-3 months or longer depending on use. To sanitize it, once a week, add the sponge to a bowl of boiling water for a couple of minutes.
If you’re using the sponge daily, be mindful it may deteriorate faster. If you see a difference in color, texture, or a strange smell, replace it.
Getting the scrubber pack is ideal because you’ll get three sponges in one pack, enough to last months!
Konjac Sponge vs Face Wipes
While makeup wipes may be considered easy and convenient, they also tend to be saturated in harsh chemicals that can irritate your skin (some may even contain PFAs).
Plus face wipes are single-use, meaning they’ll end up in a landfill somewhere or worse – fatbergs. Fatbergs are massive, solidified blockages in sewer systems made up of oils, grease, fats, and non-biodegradable items (like wet wipes).
Whatever you choose to use, never flush face wipes down the toilet – even if it says flushable.
Konjac sponges are reusable and capable of removing your makeup without the use of questionable ingredients. Just soak it in water, add your favorite cleanser, and watch the grime and makeup come right off!
And when they’re at the end of their life, they can be composted, instead of polluting our sewers.
Is a Konjac Sponge Worth It?
Yes, a konjac sponge is worth it (specifically Casamera’s) and here’s a quick recap as to why:
- Made using 4 clean ingredients (konjac powder, water, walnut shells, + infusion)
- Gently exfoliates + washes skin
- 100% compostable, doesn’t shed microplastics
- Easy to use in 5 steps
- Comes in a variety of infusions for every skin type
- Will last 2–3 months or longer depending on use
- Ships plastic-free

Best of Sustainability In Your Ear: Carbon Direct Chief Scientist Julio Friedmann on the Path to Carbon Removal
The scale of our climate challenge is staggering: humans have pumped 1.6 trillion tonnes of carbon dioxide into the air and oceans since 1750, and we’re adding another 40 billion tonnes every year. Even with dramatic emissions reductions, we’re still on track to blow past 1.5 degrees of warming, the Paris Accord target first breached in 2024. Tune in to a conversation with Dr. Julio Friedmann, Chief Scientist at Carbon Direct. This carbon management company partners with Fortune 500 companies such as Microsoft, JPMorgan Chase, and American Express to transform net-zero commitments into science-backed action plans. After a career that began as a researcher at ExxonMobil and included service at Lawrence Livermore National Laboratory, Columbia University’s energy policy center, and running advanced energy programs in the Obama administration’s Department of Energy, Julio brings unique expertise to the intersection of massive climate challenges and current technological capabilities.
As companies work toward 2030 and 2050 carbon goals, the question isn’t whether we’ll need massive carbon removal—it’s whether we can deploy it fast enough and fairly enough to matter. The recent $100 million XPRIZE Carbon Removal awards highlighted the diversity of approaches being pursued, with natural solutions like enhanced rock weathering using basalt and azomite soil, and biochar applications to farmland dominating the winners. But how do these technologies stack up against the hype? Friedmann provides a realistic assessment of where Direct Air Capture, ocean alkalinity enhancement, and other carbon removal approaches stand today. Carbon Direct’s team of 70+ scientists changes the conversation with corporate clients about their carbon strategies, providing the scientific firepower to offer hard feedback about what’s needed to preserve the markets, supply chains, and revenue streams companies depend on.
