Metal Content in Lip Products

Beginning in 2007, the U.S. Food & Drug Administration (FDA) began researching lead in lipstick based on findings by consumer watchdog group Campaign for Safe Cosmetics.  Lip products in particular are a concern based on their higher risk of ingestion.  In 2010, expanded research revealed lead in over 400 different lipsticks by various brands.

Using Hemp to Extract Heavy Metals

Using Hemp to Extract Heavy Metals
Scientists at Colorado State University (CSU) are researching how hemp can naturally clean contaminated soil.  This natural process is known as “phytoremediation”.  It involves using living plants, in this case hemp, to detoxify the soil through natural, biological, chemical or physical activities and processes of the plant.  The CSU scientists [...]

LEVITATING DROPLETS OF WATER TO DETECT HEAVY METALS

Scientists in Mexico have discovered how to detect heavy metals in water by using sound waves to levitate and analyze droplets in mid air. Isolating the droplet by this method allows the water to evaporate in a controlled position, which increases the mass concentration of contaminants.  This also makes it easier to perform a [...]

FDA PROTECTING US FROM TOXIC METALS IN OUR FOOD

The US Food and Drug Administration (FDA) recently released an interview with Conrad Choiniere, the chair of the Toxic Elements Working Group.  This workgroup of food safety experts was established about a year ago with the purpose of helping to shape what the FDA will do to protect consumers from toxic metals found in foods.  [...]

PEAT MOSS USED TO FILTER OUT HEAVY METALS

Yet another new procedure is being reported to combat heavy metal polluted water. A northern Minnesota company is touting a pollution-fighting peat!  American Peat Technology processes enormous amounts of peat from the bed of an ancient lake in Aitkin, Minnesota.  The peat has been decomposing for thousands of years and has the natural ability [...]

Treating Toxic Wastewater with Seaweed?

Wastewater containing toxic heavy metals & industrial dyes is a serious environmental dilemma.  Scientists in India have developed a nanomaterial drawn from seaweed to effectively treat toxic wastewater. Membrane-based filtration generally can’t filter out heavy metal pollutants, but researchers have synthesized a carbon based nanocomposite derived from seaweed which has shown a strong absorption capacity [...]

SCIENTISTS ABLE TO EXTRACT LEAD & MERCURY FROM WATER IN SECONDS!

Scientists from EPFL (A research institute & university in Switzerland) along with colleagues at UC-Berkeley & Lawrence Berkeley National Laboratory have developed a way to remove toxic heavy metals from water in a matter of seconds, making it drinkable. The solution uses metal organic frameworks (MOFs), which are materials made up of metal nodes [...]

Toxic Heavy Metals Found in E-Cigarette Aerosols

Researchers have discovered an alarming amount of toxic heavy metals in e-cigarette aerosols. The aerosol which a smoker inhales is created from an e-liquid which is heated by a metallic coil in the smoking device.  56 of these devices were analyzed and many had toxic levels of chromium, nickel, and lead.  Heavy metals manganese [...]

THERE’S GOLD IN THEM THAR BACTERIA!

Usually, to extract gold from ores, you must boil the ores in liquid mercury until only the gold remains.  This is a dangerous process since mercury is one of the most toxic of all heavy metals.  It’s also an environmental concern, due to the eventual disposal of the leftover mercury.  Enter a microscopic, soil-living bacterium [...]

Massive Amounts of Mercury Found in Thawing Alaskan Permafrost

Scientists estimate that more than 15 million gallons of mercury are contained in the frozen permafrost regions of Alaska.  When including the non-frozen soils of these regions, the amount more than doubles making it the largest concentration of natural mercury on Earth!  Increasing temperatures have the potential to thaw permafrost in the northern hemisphere, which [...]
