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.

Make Earth Day 2026 the next step in your response to the environmental damage inflicted by recent U.S. policy reversals that have gutted decades of effort to preserve the climate our species—and all of nature—depends on. EarthDay.org has declared this year’s mission, to make “Our Power, Our Planet” the basis of celebrations on April 18th, a day of action, and April 22nd, the traditional date for Earth Day. Don’t just sit and savor nature, step up to the resist the forces dismantling the environmental protections that followed from the first Earth Day in 1970, which led to the creation of the Environmental Protection Agency, Clean Water Act, and Clean Air Act, among so many important national efforts.

The global market for natural health products now exceeds $300 billion, and parents are leading the charge — looking for gentler, plant-based alternatives to synthetic medicines for their kids. Some natural remedies have centuries of traditional use behind them. Others have meaningful clinical support. And a few carry real safety caveats that are easy to miss when you’re shopping for a more natural medicine cabinet.
Four ingredients cover a lot of ground: coconut oil, essential oils, honey, and apple cider vinegar. Here’s what the evidence says about each, including what to watch out for, especially with younger children.

1. Coconut Oil
Coconut oil earns its place in a natural medicine cabinet through sheer versatility. Applied topically, it works well as a balm for chapped cheeks, a diaper rash treatment for babies, a soothing after-bath moisturizer for dry skin, and as a carrier oil when diluting essential oils for topical use. It’s also a perfectly serviceable cooking oil — just keep separate containers to avoid cross-contamination between cosmetic and kitchen uses.
Look for unrefined, virgin coconut oil — it retains more of the naturally occurring medium-chain fatty acids (including lauric acid, which has demonstrated antimicrobial properties in lab studies) compared to refined versions. Nutiva Organic Virgin Coconut Oil is a consistently available option.
2. Essential Oils: Effective, But Use With Care
Essential oils are concentrated plant extracts potent enough to have real therapeutic effects, and potent enough to cause real harm if misused. For kids, the most useful are:
- Lavender oil soothes minor skin irritation, helps with relaxation, and has mild antiseptic properties. It’s one of the gentler oils for children. Plant Therapy Lavender Essential Oil is a reputable, widely available option.
- Tea tree oil (melaleuca) is a well-documented antiseptic useful for skin rashes and has shown effectiveness against head lice. NOW Tea Tree Oil is a reliable choice.
- Eucalyptus oil supports respiratory comfort when diffused and can be used in a natural chest rub for older children. Plant Therapy Eucalyptus Globulus is a good starting point. For children under 2, eucalyptus in any form should be avoided. For children ages 2–4, use only with extra caution and well-diluted.
Eucalyptus age limits: Eucalyptus age limits: The blanket warning “never use on children under 10” guidance circulating online is an overstatement. The European Medicines Agency concludes that eucalyptus used by inhalation, topically, or as a bath additive is appropriate from age 4, and that oral use is restricted to age 12 and up. Do not apply near the nose, mouth, or face of any young child. Robert Tisserand and Rodney Young’s Essential Oil Safety (2nd ed., 2014), the field’s standard reference, supports this more nuanced reading.
Lavender and tea tree and hormonal concerns with boys: Research published in the New England Journal of Medicine found a link between topical use of lavender and tea tree oils and hormonal disruption in prepubescent boys. Aromatherapy (diffusing) is the lower-risk alternative for this age group.
Always dilute essential oils. Undiluted oils should never be applied to a child’s skin. For children under 2, use a 0.5–1% dilution in a carrier oil (like coconut or almond oil). For ages 2–6, 1–2% is appropriate.
No peppermint for children under 30 months. Peppermint oil can increase seizure risk in very young children and should be avoided.
For a comprehensive reference, Johns Hopkins Medicine’s essential oil safety guide for children is a solid starting point. And check with your pediatrician before introducing new oils, especially for children with respiratory conditions.
3. Honey: Powerful Medicine — With A Critical Exception
Raw honey does considerably more than sweeten tea. Applied topically, it’s an effective treatment for acne, particularly raw honey, which retains more antimicrobial compounds. Manuka honey from bees that pollinate the New Zealand mānuka bush has demonstrated well-documented antibacterial properties and is worth keeping on hand for wound care and throat soothing.
For throat relief, a spoonful of honey dissolved in warm water with lemon is effective for children over 1 year old. Look for raw Manuka honey rather than processed honey in a plastic squeeze bottle, which has been heated and filtered to the point of losing most of its beneficial properties.
| Critical Safety Warning — Honey and Infants: The FDA, CDC, and American Academy of Pediatrics all recommend that honey never be given to children under 12 months of age — in any form, including baked goods, cereals, or foods that contain honey as an ingredient. Honey can harbor Clostridium botulinum spores, which can cause infant botulism, a serious and potentially fatal illness. Infants’ digestive systems are not mature enough to neutralize the spores. This restriction applies to raw honey, pasteurized honey, and honey in cooked or processed foods. After age 1, honey is safe. |
4. Apple Cider Vinegar
Apple cider vinegar’s acidic properties make it useful for a handful of topical applications. Two cups diluted in bathwater can help soothe eczema flares; diluted 50/50 with water, it’s effective for sunburn relief and itchy skin.
Its strong taste makes internal use a tough sell for kids, but they can still benefit from external applications. As with honey, quality matters: get an unfiltered, unpasteurized brand that retains “the mother” — the strand-like protein-enzyme matrix that forms during fermentation. Bragg Organic Raw Apple Cider Vinegar is the go-to product and is widely available.
A note on internal use for older kids and adults: ACV is acidic enough to erode tooth enamel if taken undiluted or frequently. Always dilute in water and consult a healthcare provider before making it a regular supplement.
These four ingredients are a good starting point for your own natural healing remedies. Simple and straightforward, most will be readily available at your local health food store and are a cinch to apply or administer.
Building Your Natural Medicine Cabinet
These four ingredients give you solid coverage for common minor ailments — skin irritation, dryness, colds, scrapes, and more. Most are available at natural grocery stores; the essential oils are easy to find online from reputable brands like Plant Therapy, NOW, and Edens Garden, all of which publish third-party testing data.
Start simple, read the labels carefully (especially age guidance on essential oils), and keep products stored out of reach of young children. When in doubt, your pediatrician is the right call.

Spring is officially here, inspiring gardening plans as well as dread of lawn chores. Before you immerse yourself in another year of yard maintenance, we have a question for you: When was the last time you reevaluated your yard maintenance tactics and outdoor plant selections? An environmentally friendly approach to a low-maintenance yard can save you money, time, and effort while it benefits the local ecosystem.
By carefully selecting the right plants, including natives and perennials, you can minimize watering and yearly plantings — resulting in less work for you and a lower water bill. And by employing natural gardening techniques, such as composting and companion planting, you can keep your soil healthy and keep pests away — without chemicals.
Naturally, a healthy and biodiverse yard looks different depending on your climate and region. Are you familiar with the plants that are native to your region? It’s exciting to choose the optimal plants for your garden because you know you’re giving them the best chance of success — plus, you’re helping the surrounding ecosystem.
Before selecting your plants, be sure to check the noxious weed lists or your county extension office to make sure you don’t pick invasive plant species. Some low-maintenance plants may be invasive in your region. For example, English Ivy, an attractive, low-maintenance vine, is an aggressive invader and on the noxious weed of the United States list.
With careful plant selection and eco-friendly gardening strategies, you’ll enjoy a low-maintenance yard, save money, and benefit Mother Earth too! Check out the tips and plant recommendations in the following infographic from HomeAdvisor.
