New Research Finds Heavy Metals Linked to Heart Disease & Stroke

According to research published in the British Medical Journal, exposure to heavy metals like lead, arsenic, cadmium and copper may lead to an increased risk of heart disease and stroke. Researchers performed a meta-analysis of 37 unique studies comprised of nearly 350,000 participants from different parts of the world.  The study found that the greater [...]

Lead Poisoning on U.S. Army Bases Reported

A recent investigative report by Reuters claims that at least 31 children who lived in on-post housing at the Army’s Fort Benning in Georgia tested high for lead.  Additionally, at least 77 more children tested high for lead at Fort Polk in Louisiana, Fort Riley in Kansas, and Fort Hood & Fort Bliss in Texas.  [...]

Tropical Plant Removes Toxic Heavy Metals from Britain’s Rivers

A new study has found that the water hyacinth plant is successful in removing toxic heavy metals from the River Tawes, south of Wales.  The invasive tropical plant removes pollutants using a process known as phytoremediation.  Using living plants to clean contaminated water is cheaper and more environmentally friendly than other conventional methods.  The water [...]

Paper Water Filters Developed to Remove Pollutants, Including Toxic Heavy Metals

Scientist Liangjie Dong from the University of Hawaii has created an easy-to-use paper water filter called Mesopaper. The filter uses three layers of paper made from bamboo fiber with ceramic granules manufactured from clay sandwiched in between.  The granule’s pores are tiny enough to trap heavy metals like arsenic, lead or mercury, while at [...]

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.
In [...]

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 [...]


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 [...]


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.  [...]


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 [...]
