New research has reported a link between elevated blood levels of perfluooctane sulfate (PFOS) and increased risk of liver cancer. The study is the first to directly associate exposure from this “forever chemical” to liver cancer in humans.

A striking new article argues the global spread of certain hazardous chemicals is so pervasive that unsafe levels of PFAS chemicals can be found in rainwater all over the world, including remote areas such as Antarctica and the Tibetan Plateau.

Researchers have found strong evidence exposure to a common group of household chemicals can be associated with 13 different health conditions. The related economic costs have been estimated at between US$5 billion and $60 billion annually in the US.

A new report has estimated more than 10 percent of all cancer cases in Europe are likely caused by environmental and occupational exposure to pollution. The report indicates most of these cases could be prevented by improving environmental protections.

A world-first clinical trial has found blood or plasma donations can reduce levels of toxic PFAS chemicals by up to 30 percent. The trial is the first to find an effective intervention that reduces blood levels of substances known as “forever chemicals”.

Striking new research estimates lead exposure, primarily from car exhaust in the 1960s and 1970s, has negatively affected the IQ of more than half the population of the US, and resulted in the loss of up to six IQ points in some people.

A study is outlining strategies that should be employed by cannabis growers to mitigate the plant’s ability to absorb heavy metals from soil. The study indicates it is possible cannabis contaminated with heavy metals could lead to chronic diseases.

A new study is reporting half of US children under the age of six have detectable levels of lead in their blood. The study tracked data from over a million children and is the first of this scale to analyze small traces of lead in blood samples.

A striking new study testing a number of over-the-counter weight loss and sports supplements has found they contain many combinations of stimulants that have either previously been prohibited by the FDA or never approved for human consumption.

Although there already are devices that can detect harmful gases, most of them aren't particularly portable or simple to use. An experimental new tool, however, is about the size of a hypodermic needle – and it could be utilized by anyone, anywhere.

The ingenuity of bacteria keeps surprising scientists. The latest example is a species called Geobacter sulfurreducens, which has now been found to survive exposure to toxic cobalt by building a metal “suit” like a tiny little Iron Man.

Often made from plants, recycled material and various forms of organic matter, bioplastics promise a number of advantages over conventional plastics produced through fossil fuels, but a new study suggests that safety may not be one of them.
