A fern species that flourishes in the mossy slopes of an open pit copper mining site in Surigao del Norte, a province in Mindanao. Teresita Perez / Mongabay<p>"We are interested in metallophytes … plants that grow on mining areas," Claveria says. "While analyzing all these plants, we decided that fern is the most suitable for our study because they have higher amounts of absorbed copper and arsenic and other metals."</p><p>The decision to narrow down to ferns came with scholarly backing: the <em>Pteris</em> genus, which includes around 300 species of ferns, feature other popular metallophytes that absorb arsenic. But unlike other widely researched species, <em>P. melanocaulon</em> was mostly unknown, in part due to the scarcity of research journals on the plant. Existing surveys conducted by the team across various large- and small-scale mining sites showed that it only proliferates in two areas in the Philippines.</p><p>"When we focused on ferns, there was one that stood out: the <em>P. melanocaulon</em>, which we didn't see in any other mining sites we surveyed," Claveria says. "We found it in Surigao [del Norte] and later on, in Carmen [in Cebu province] … and this fern happens to grow in areas [within these sites] that are supposedly barren."</p><p>The mossy open slopes left behind by open pit mines, notorious for their high levels of arsenic and copper concentrates, were the perfect breeding grounds for <em>P. melanocaulon</em>, which thrive in lush clusters that overpower the other plants in the Surigao del Norte mining site, Claveria says. Curious about the fern, they recovered samples and conducted initial tests to measure its copper absorption capabilities in 2014.</p><p>The results showed that the plant's roots have "anomalously high" concentrations of copper, Claveria says. After publishing their findings in the <em>International Journal of Phythoremediation</em> in 2015, the team expanded their research on the plant and threw arsenic into the mix.</p>
Rene Claveria and Teresita Perez examining plants in Surigao del Norte. Teresita Perez / Mongabay<p>The logic was since the fern survives alongside other species that are known arsenic metallophytes, maybe it could also absorb arsenic.</p><p>After collecting another set of samples, they conducted a series of tests that verified their hypothesis: the fern does indeed absorb the toxic mineral and stores it in its stems and leaves. They took the research a little further and funded a greenhouse to propagate spores of <em>P. melanocaulon</em> at Xavier University in Cagayan de Oro province, where they experimented with the potted plants.</p><p>They added different concentrations and solutions of arsenic to uncontaminated soil in a series of experiments that lasted for six weeks. The plant's ability to absorb arsenic varied, adjusting to the concentration of the element in the soil, much to the researchers' surprise. The team noted two important observations: that the fern contained more arsenic concentrate than the soil it was planted on, and that despite exposure to high levels of arsenic, it showed no symptoms of toxicity.</p>
Rene Claveria collecting soil samples in Surigao del Norte. Teresita Perez / Mongabay<p>"If you use the ferns to clean up arsenic, which is very toxic, there could be colonization or succession of plants," Perez says. "Eventually, a year after or after one and a half years, you can already plant some high value crops in the area."</p><p>With the protocol in the propagation of the fern species in the books, Perez says the possibility of using the fern to rehabilitate mining soil on a large-scale project is possible. But first, she says, decision-makers should be aware of metallophytes — and that there are indigenous plants that can be used as natural remedies to alleviate mineral-heavy soils.</p><p>"We have to recommend to our policymakers the use of indigenous plant materials to actually clean up arsenic-contaminated areas," Perez says. "In the past, rehabilitating mining sites involved planting invasive species — that was really a wrong move. But now, we're propagating the idea of indigenous and endemic species so these areas can develop new ecosystems."</p>

Arica is a dusty, windswept port city in northern Chile. Tourists wander the city's long seafront under the shadow of a dramatic buff-colored cliff called El Morro. But the bracing sea air belies a toxic controversy that has bounced from court to court, from Chile to Sweden, in vain search of resolution.
Today, the waste is walled off but still exposed to the elements, just five minutes' walk from the nearest social housing.
The waste is now just outside the impoverished Cerro Chuno neighborhood of Arica, where most residents are migrants.

Heavy metals that may damage a developing brain are present in 95 percent of baby foods on the market, according to new research from the advocacy organization Healthy Babies Bright Futures (HBBF), which bills itself as an alliance of scientists, nonprofit organizations and donors trying to reduce exposures to neurotoxic chemicals during the first three years of development.

World War I ended 100 years ago on Sunday, but 42,000 acres in northeast France serve as a living memorial to the human and environmental costs of war.
The battle of Verdun was the longest continuous conflict in the Great War, and it so devastated the land it took place on that, after the war, the government cordoned it off-limits to human habitation. What was once farmland became the Zone Rouge, or Red Zone, as National Geographic reported.

What keeps you up at night? Sick kids, restless pets, the latest tragedy on the evening news, politics, wars, earthquakes, hurricanes, fires, money troubles, job stress, and family health and wellbeing? There is no shortage of concerns that make us all toss and turn.

Arsenic, lead, and cadmium are chemicals you'd expect to find in rat poison and batteries—not baby formula.
But on Wednesday, the Clean Label Project, an initiative that tests products for industrial and environmental contaminants and rates them, said it found arsenic in 80 percent of infant formulas, according to USA Today. In fact, the study—which has not been published in a peer-reviewed journal—found that certified some organic baby food products had more than twice the amount of arsenic found in the conventional baby foods it tested.
For decades all across America, coal-fired power plants have dumped tons of toxic pollutants into public rivers, lakes, streams and coastal waters. On a toxicity-weighted scale, discharges from coal-fired power plants account for over one half of all toxic water pollution in the U.S. The pollutants dumped by coal-fired power plants are among the most toxic heavy metals listed by the U.S. Department of Health’s Agency for Toxic Substances and Disease Registry, including arsenic, cadmium, chromium, lead, mercury and selenium.
The Sutton coal-fired power plant in Wilmington, NC, is a prime example of a coal-fired power plant with a long history of groundwater pollution, surface water contamination and government failure to prevent harm to public waterways.
Underneath the sand and pine trees that surround Sutton, an unseen plume of toxic heavy metals has migrated out of the unlined ash ponds into groundwater. Monitoring well data from the site show the ash ponds have caused numerous pollutants to exceed their respective standards, including:
- Arsenic at 34 times the standard
- Manganese at 47 times the standard
- Iron at 27 times the standard
- Boron at four times the standard
- Sulfate more than three times the standard
- Thallium at three times the standard
- Selenium at more than twice the standard
- Total Dissolved Solids at twice the standard
Unbeknownst to most of the people living in Wilmington, NC, this hidden toxic witches brew of contamination is flowing towards public water supplies that provide drinking water to the community of Flemington. These wells are operated by the Cape Fear Public Utility Authority and are located less than a mile from the leaking Sutton coal ash ponds.

Groundwater assessments prepared by Progress Energy and submitted to the North Carolina Department of Environment and Natural Resources (DENR) have found that the contaminated groundwater flows in the direction of the Flemington community wells at a rate of between 109 to 339 feet per year. In 1994, DENR’s Division of Environmental Management Groundwater Section explained that the groundwater flow at the Sutton site is “substantially influenced by the pumping activities of the New Hanover Co. well field [i.e., the Flemington wells]” and that “[t]hese pumping activities may result in a groundwater flow pattern that moves from the lake and ash ponds toward the well field.”
Indeed, a recent report prepared by the North Carolina Division of Environmental Health, Public Water Supply Section for the water system served by the Flemington wells assigned their “Inherent Vulnerability Rating,” “Contaminant Rating” and “Susceptibility Rating” the highest risk rating and listed the Sutton facility numerous times as a “Potential Contaminant Source” for the wells. The report also confirms that many of the highly contaminated groundwater wells at Sutton are within the area that contributes groundwater to the Flemington wells.
This situation also raises an environmental justice issue. Achieving environmental justice involves identifying and addressing disproportionately high and adverse human health or environmental effects of federal programs, policies and activities on minority and low-income populations. Here, failure to enforce provisions of the Clean Water Act, to the detriment of the low-income Flemington community, is an environmental justice concern.
The other huge problem caused by decades of untreated coal ash waste being dumped into Sutton Lake is the accumulation of selenium in fish. Decades of sampling reveals that selenium concentrations have increased dramatically over time, such that in recent years the selenium concentrations in the surface water reached levels that cause reproductive failure of fish and waterfowl and have far exceeded those levels in the lake sediments and in fish tissue itself. The North Carolina Wildlife Resources Commission (WRC) determined that the sediment and fish tissue concentrations represent a “High” hazard. Unsurprisingly, the most recent published assessment of the lake by WRC noted that largemouth bass in Sutton Lake were in poor condition, and that from 2008 to 2010, the abundance and size of the largemouth bass population declined by 50 percent.
Sutton Lake is an extremely popular fishing location. It is frequented both by sport fishermen and by subsistence fishermen, who catch fish that are eaten by themselves and their families. Despite the fact that untreated coal ash sluice water, coal pile runoff, chemical metal cleaning wastes and other wastewater is discharged directly into the public waters of Sutton Lake, the public is encouraged to fish there. As selenium levels rose in fish in recent years, the state of North Carolina could have informed the public that the fish in Sutton Lake are in poor health. But in actuality boat ramps and fishing piers were recently improved to provide even greater public access and allow more people to catch and eat the fish out of Sutton Lake.
