Analysis of mutated fern spores sheds light on link between mercury and mass extinction
A study published in the journal Science Advances found that increased mercury levels in the environment may have contributed to the mass extinction more than 200 million years ago. An international team of researchers analyzed mutated fern spores from core samples dating to that period and found a strong link between mercury and the mass extinction event. “By looking […]

Animal study reveals cadmium exposure and Alzheimer’s risk gene may be linked to cognitive impairment
Researchers at the University of Washington found that cadmium exposure, combined with a genetic predisposition to Alzheimer’s disease, might accelerate cognitive decline. The researchers arrived at this finding after exposing mice with an Alzheimer’s risk gene to cadmium. They detailed their findings in a paper published in the journal Toxicological Sciences. The effects of cadmium plus an Alzheimer’s risk gene The […]

Lifetime exposure to lead linked to greater dementia risk
A study published in the Journal of Alzheimer’s Disease suggests that lead might play a role in the development of dementia. Researchers from the University of Toronto (U of T) reported this after finding a link between lifetime lead exposure and greater dementia risk. In particular, they found that dementia cases decreased as the use of lead declined over […]

Unsafe levels of strontium found in drinking water of 2.3 million Americans – study
A study from the U.S. Geological Survey (USGS) shows that the drinking water of 2.3 million Americans contains unsafe levels of naturally occurring strontium, a metal that can negatively impact bone health in children. MaryLynn Musgrove, a scientist at the USGS’s Oklahoma-Texas Water Science Center and the author of the study, found that more than two percent of water […]

Turmeric from Bangladesh sometimes contains lead-laced chemical compounds, study finds
American and Bangladeshi researchers found that turmeric is occasionally laced with lead in Bangladesh, one of the world’s leading turmeric-growing regions. In a study published in the journal Environmental Research, the team revealed that most of the surveyed districts added lead to turmeric to make them look more yellow. Turmeric producers add lead for color Previous studies implicated turmeric […]

Chemical reaction between pipe alloy and water disinfectants produce cancer-causing chromium in drinking water
Researchers from the University of California, Riverside have found that pipe alloy can react with residual water disinfectants to produce cancer-causing chromium that gets mixed in drinking water. In a study published in the journal Environmental Science & Technology, the researchers said that chemical reactions can change chromium in water pipes into a form that creates genetic mutations in cells. […]

Scientists develop an electrochemical process that removes toxic mercury from contaminated water
Researchers from the Chalmers University of Technology in Sweden developed a method that can remove nearly 100 percent of toxic mercury from contaminated water. In a study published in the journal Nature Communications, the researchers said that the electrochemical process works by encouraging mercury ions to form an alloy with another metal. This effectively draws the heavy metal out […]

Potential threats to child brain health: Daily exposure to heavy metals in baby food could build up over time, warns experts
Baby foods are laced with trace amounts of toxic heavy metals that can build up over time through daily exposure and impair children’s brain health, reported the consumer advocacy group Healthy Babies Bright Futures (HBBF). The organization found that 95 percent of nearly 170 commercial baby foods contained lead, arsenic, mercury and cadmium, with one in four products […]

Science explains why your tap water isn’t safe
Many Americans rely on tap water for their drinking water. Modern sanitation technologies made it possible to eliminate biological contaminants from public water systems, making tap water clean drinking. But another threat to safe water has emerged in the past years. Research found that domestic water systems in the United States are exposed to a lot of […]

Tattoos can leak dangerous heavy metals into your lymph nodes, study finds
A recent study published in the journal Particle and Fibre Toxicology found that tattoos can leak dangerous metals into the lymph nodes and trigger an allergic reaction. The culprit is an abrasive chemical called titanium dioxide that erodes the ink needle and sheds the metals. The European researchers initially attributed the presence of metal nanoparticles in tattooed people’s […]
