Alongside being used as the album's title, the phrase "mercury falling" appears as the first and last lyrics heard on the album. The lyric was the first written for the album (for "The Hounds of Winter"), and Sting later felt the phrase evoked the mood of the record and its variety of styles: "there are so many styles on this record and it darts around from genre to genre and back again. It's a very mercurial record, and it seemed to be the right thing to call the record."[11]
MEET Filipino gold miner Leoncio Na-Oy. For almost a decade, Na-Oy has been working with international NGO Pure Earth to test and teach a century-old, traditional method of mercury-free gold mining that local miners practised in his hometown of Benguet in the Philippines.
Na-Oy turned to gold mining 33 years ago when he could not find a job after graduating with a history degree. He began practising the local, traditional technique used by miners in his village, but he also saw miners using mercury that was introduced by large-scale mining concerns in the 1960s and 70s.
Even in small amounts, mercury may cause serious health problems, and is a particular threat to the development of infants in utero and in early life. Mercury disrupts the physiological and neurological development of children, attacks the central nervous and immune systems, targets organs, and in higher doses, it can kill.
While gold miners and their families and community are most directly impacted by their use of mercury, the toxin also has the ability to travel far and wide, dropping into rivers and oceans, where it accumulates in fish and shellfish that is consumed worldwide. This is one reason why pregnant women everywhere are often warned against eating fish.
As a vocal proponent of the mercury-free method, Na-Oy has worked to adjust and update the traditional Benguet method over the years in order to make it more efficient, adaptable, and therefore attractive to gold miners worldwide.
The steps to extracting gold are similar the world over but with variations, depending on the terrain, the quality of ore, and other factors. But it almost always involves using mercury to bind small grains of gold into an amalgam, which is then burned off, releasing vaporized mercury into the environment and atmosphere, leaving behind the gold.
Because different methods are viable in different mining locations, Pure Earth is exploring a variety of techniques to reduce mercury, offering a range of solutions to miners around the world. Na-Oy and his team help by testing and adjusting their mercury-free method to suit each mining community. Here is what going mercury-free looks like in the mountains and rainforest of Peru.
In 2016, Peru declared a state of emergency in Laberinto and other districts of Madre de Dios, due to widespread mercury pollution caused by artisanal and small-scale gold mining activities in the Peruvian Amazon.
Instead of mixing the gold-rich alluvium with mercury, Na-Oy instructs the miners in Laberinto to add water to the alluvium and pan. Na-Oy demonstrates to the miners that what he gets with panning is a more concentrated gold mixture, which he then burns off with non-toxic borax, rather than mercury.
In areas like these, where mercury is being extracted from soft alluvium, the mercury-free technique does not require much investment in new equipment, which makes it easier for miners to adopt. All miners need to do is purchase a pan and practise panning.
The crushed ore is then placed under large boulders along with elemental or quicksilver mercury. A man (sometimes a child) is tasked with standing on the boulder, rocking it back and forth, sometimes for hours. This force helps to bind the mercury to the gold, creating an amalgam.
During this process, mercury is released into the air and water. In such close proximity, the miners are all exposed to danger. They wear no protective gear except hard hats, and use their bare hands to sift through the water and handle mercury.
Instead of using mercury, Na-Oy teaches the miners in Ollachea to separate gold from the crushed ore by sluicing. This is done in a sluice that he shows them how to build using simple materials. When complete, the sluice box has several chutes that fit together like a water slide.
If all miners worldwide could be convinced to switch to a mercury-free method, it would not only radically lower the amount of mercury released into the atmosphere globally, but it will also improve the health of millions who live near and far from gold mining activity worldwide.
Over the last year, we've watched Ford officials desperately plugging the fruits of their 'reinvigorated' Mercury brand. The Blue Oval's trumpeted reinvestment into the fallen badge can be summed-up thusly: more reheated Fords in shinier tins. The main difference from previous attempts to keep the former purveyor of flatheads from flat-lining lies in Ford's willingness to tarnish old monikers like Monterey, Montego and Marauder to sell a few extra units. What's old is new again, and vice-versa.
Locate visible mercury beads. Use a squeegee or cardboard to gather mercury beads into small mercury balls. Use slow sweeping motions to keep mercury from becoming uncontrollable. Take a flashlight, hold it at a low angle close to the floor in a darkened room and look for additional glistening beads of mercury that may be sticking to the surface or in small cracked areas of the surface.
Use the eyedropper to collect or draw up the mercury beads. Slowly and carefully squeeze mercury onto a damp paper towel. Alternatively, use two pieces of cardboard paper to roll the mercury beads onto the paper towel or into the bag. Place the paper towel in a zip locking bag and secure. Make sure to label the bag as directed by your local health or fire department.
After you remove larger beads, put shaving cream on top of small paint brush and gently "dot" the affected area to pick up smaller hard-to-see beads. Alternatively, use sticky tape, such as duct tape, to pick up any remaining small glass fragments (peel the tape very slowly from the floor to keep the mercury beads stuck to the tape). Place the paint brush or duct tape in a zip locking bag and secure. Make sure to label the bag as directed by your local health or fire department.
Place all materials used with the cleanup, including gloves, in a trash bag. Place all mercury beads and objects into the trash bag. Place the trash bag outside in a secured area and label it as directed by your local health or fire department.
Remember to keep the area well ventilated to the outside (i.e., windows open and fans in exterior windows running) for at least 24 hours after your successful cleanup. You may want to request the services of a contractor who has monitoring equipment to screen for mercury vapors. Consult your local environmental or health agency to inquire about contractors in your area.
If sickness occurs, seek medical attention immediately. View information on health effects related to exposures to vapors from metallic mercury. For additional information on health effects, the Agency for Toxic Substances and Disease Registry (ATSDR) provides a Public Health Statement on Mercury that also presents information on health effects related to exposures to vapors from metallic mercury.
FEMC conducts year-round sampling of precipitation chemistry at the air quality monitoring site at the Proctor Maple Research Center in Underhill, Vermont. Weekly composites of precipitation are gathered in an automated wet-only precipitation collector at the site. The collector opens automatically when rain or snow is detected, capturing precipitation through a funnel and tube sampling train into a bottle charged with hydrochloric acid (to preserve the sample). The collector is heated in the winter and vented in the summer as needed. Samples are collected every Tuesday and shipped to the Mercury Analytical Laboratory at Eurofins Frontier Global Science, Inc. in Bothell, WA for analysis of mercury concentration and cleaning of the sampling train. Data are submitted to NADP for quality control and posted on the NADP/MDN website ( ).
Mercury monitoring at FEMC's air quality site (VT99) for 2016 shows slightly lower deposition than average for the 11-year record, higher than 2015 and roughly equal to 2014 (Table 2). Over the entire record for VT99, total mercury deposition fluctuated from a high of 11.6 µg/m2 in 2007 to a low of 6.1 µg/m2 in 2012 and 2015. Similarly, the precipitation-weighted mean mercury concentration and the maximum mercury concentrations measured at VT99 are quite variable. In 2016, precipitation-weighted mean concentration was roughly average for the record, while the maximum recorded concentration in a single sample was well below historical average. In 2016, Vermont registered lower concentration and deposition averages that most sites elsewhere in the United States (Figure 12).
Over 10 years of monitoring at VT99 prior to the current year, mean annual deposition was higher than 41% of national MDN sites (Table 3). The VT99 monitoring station has fallen from the high end of measured values (2007, with higher total Hg deposition than 85% of other MDN sites) and climbed from the low end of measured values (2012, with higher total Hg deposition than only 14% of other MDN sites). During most years of monitoring, the VT99 site typically falls in the middle of reported Hg deposition values across the Mercury Deposition Network.
Indeed, a recent regional trends analysis using NADP MDN data (Figure 14) provides further signs of regional differences for VT99. Different periods were analyzed, including the years 1997-2013 as well as several shorter portions of the record. The shorter time period analyses were a way to incorporate the changing spatial pattern into the trends analysis as the MDN network expanded. This period from 2008 to 2013 shows VT99 having a statistically significant positive slope in increased mercury concentrations. Five years is too short for a definitive trend, but it might suggest that VT99 is more influenced by global sources than are surrounding lower altitude MDN sites due to its relatively high altitude and the absence of nearby coal utility boilers (Weiss-Penzias et al. 2016).
