Arsenic is a naturally occurring element widely distributed in the earth’s crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.
Breathing high levels of inorganic arsenic can give you a sore throat or irritated lungs.
Ingesting very high levels of arsenic can result in death. Exposure to lower levels can cause nausea and vomiting, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels, and a sensation of “pins and needles” in hands and feet.
Ingesting or breathing low levels of inorganic arsenic for a long time can cause a darkening of the skin and the appearance of small “corns” or “warts” on the palms, soles, and torso.
While metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with obesity, the cause of its rapidly rising prevalence is not well understood. In this study, we aimed to examine the association between arsenic exposure and MASLD in humans.
Spina bifida is among the most common and debilitating neural tube defects, affecting approximately 1 in every 2,875 newborns in the United States.
Research led by the University of Arizona Health Sciences found a potential link between growth problems among infants and high levels of toxic metals and other elements in the breast milk of Mayan women in Guatemala's Lake Atitlán watershed region.
Researchers found that most fish sampled from Ghana’s Keta Lagoon had arsenic and mercury levels exceeding World Health Organization limits. Health risk assessments show these contaminants pose significant cancer and non-cancer risks, especially for children.
Drinking water treatment that pursues a multi-contaminant approach, tackling several pollutants at once, could prevent more than 50,000 lifetime cancer cases in the U.S., finds a new peer-reviewed study by the Environmental Working Group.
Researchers at Zhejiang University School of Medicine have identified a single point mutation in the normal PML gene that can block the effect of arsenic trioxide, a frontline drug for acute promyelocytic leukemia.
In a recent publication released by PubMed, American scientist Dr. Renee Dufault at the Food Ingredient and Health Research Institute, provides a peer-reviewed protocol for determining the role ultra-processed foods play in prenatal heavy metal exposures and changes in the expression of the zinc dependent MT-1 (metallothionein) gene that impact child neurodevelopment.
Babies born to mothers potentially exposed to low levels of arsenic in public drinking water-even at levels below the federal safety standard-were more likely to be born preterm, with lower birthweight, or be smaller than expected, according to a study at Columbia University Mailman School of Public Health and funded by the National Institutes of Health's Environmental influences on Child Health Outcomes (ECHO) Program.
Esther Bejarano's son was 11 months old when asthma landed him inhh the hospital. She didn't know what had triggered his symptoms — neither she nor her husband had asthma — but she suspected it was the pesticides sprayed on the agricultural fields near her family's home.
Prenatal exposure to trace elements like selenium, copper, and arsenic can significantly alter the infant gut microbiome, metabolism, and antibiotic resistance gene patterns. These changes appear as early as three months and evolve during the first year of life.
A study by scientists at the University of California, Riverside shows ultrasonic cigarettes, or u-cigarettes, marketed as a less harmful alternative to traditional e-cigarettes, may pose significant health risks due to the presence of harmful metals in their liquids and aerosols.
Carrying eagle feathers and chanting prayers, Western Apache runners hit the road on a roughly 80-mile journey this month to try to save their sacred land from being fast-tracked by President Donald Trump into a copper mine.
The influenza virus manipulates the body's gene regulation system to accelerate its own spread, according to researchers at the University of Gothenburg.
People with plaque in the blood vessels of their neck have a higher amount of tiny plastic particles in those vessels compared to people with healthy arteries.
Brown rice contains more nutrients than white rice, but also higher levels of inorganic arsenic, a known health risk. A US population-level study reveals that young children consuming brown rice may exceed safe arsenic intake levels.
A Ludwig Cancer Research study has identified a novel strategy for treating acute myelogenous leukemia (AML), an aggressive blood cancer for which the median survival time following diagnosis remains just 8.5 months.
Bacteria can be engineered to sense a variety of molecules, such as pollutants or soil nutrients. In most cases, however, these signals can only be detected by looking at the cells under a microscope or similarly sensitive lab equipment, making them impractical for large-scale use.
Chemicals used as food preservatives, flavoring agents, dyes, pesticides, cosmetics, cleaners, and other industrial materials are being increasingly recognized as a health hazard.
A new study in Atherosclerosis shows that soil and water pollution, including microplastics and toxic chemicals, significantly raise cardiovascular disease risks. The research highlights how emerging contaminants and poor environmental practices drive global health threats.
Microplastics and nanoplastics, two of the smallest and most invisible forms of plastic pollution, may pose risks to human health.
