Flea treatment chemicals fipronil and imidacloprid also implicated in lower cognitive scores in children with autismToxic chemicals found in pet flea treatment are devastating wildlife in rivers, parks and special conservation areas and the government should take urgent action to limit their use, according to a study.Chemicals that are banned for use as pesticides but still used in flea treatments are causing potentially irreversible harm to aquatic life as well as decimating birds and pollinators, according to the study published on Thursday.

Study of Channel finds levels of toxic Pfas in Solent at 13 times safe limits in some places, with much coming from treated sewageScientists have found high levels of toxic Pfas, or “forever chemicals”, in soil, water and throughout the marine food chain in the UK’s Solent strait, including at protected environmental sites, according to a new study.In some samples, pollution was 13 times the safe threshold for coastal waters. Others, which were below legal limits for individual chemicals, failed tests for combined toxicity. Continue reading...

EPA outlines effort to kill Biden-era rules as critics condemn RFK Jr and Lee Zeldin’s ‘hocus pocus’The Trump administration has announced a plan to kill Biden-era drinking water limits on four Pfas “forever chemicals”, and to delay the implementation of standards for two other compounds.The Environmental Protection Agency is proposing two separate rules to delay and rescind the limits. The rules must go through an approval process that can take several years, and almost certainly will be challenged in court. Continue reading...

Levels of Pfas in northern gannet eggs in Canada fell up to 74% over 55-year period of studyLevels of some of the most dangerous Pfas compounds have dramatically fallen in Canadian seabird eggs, which the authors of a new peer-reviewed study say illustrates how regulations are effective.Researchers looked at Pfas levels in the eggs of northern gannets in the St Lawrence Seaway basin over a 55-year period. Pfas levels shot up from the 1960s through the peak of the chemicals’ use in the late 1990s and early aughts, then fell. Continue reading...

NHS chiefs fear rising costs and healthcare shortages due to the shipping standstill in the GulfThe war in Iran has put the NHS on high alert amid fears about looming shortages and rising costs for medicines and medical products such as syringes, intravenous bags and gloves.Much of modern healthcare is dependent on the petrochemicals now held up by the Gulf shipping standstill – whether for active pharmaceutical ingredients or to produce the millions of sterile single-use items, ranging from personal protective equipment (PPE) to catheters and diagnostic-device casings.

Green groups say European Commission is ‘chief roadblock’ to its own plans, as report finds poor progress four years onHarmful compounds in children’s nappies and toxic “forever chemicals” in everyday products are among 14 hazardous substance groups hit by lengthy delays to EU pollution controls, according to report findings described by scientists as “extremely frustrating”.The European Commission sought to push broad categories of dangerous substances off the market with a “restrictions roadmap” in April 2022 that was hailed at the time as the largest-ever ban of toxic chemicals.

• The Biden administration announced comprehensive sanctions targeting Russian entities involved in chemical weapons production and deployment, following reports of their use against Ukrainian forces in recent weeks. • The Treasury Department froze assets of 12 Russian companies and individuals, with officials stating the measures aim to deter further violations of the Chemical Weapons Convention. • Security analysts warn that chemical weapons escalation signals Russia's desperation as its conventional military capabilities face sustained Ukrainian resistance.

• UL Research Institutes’ Chemical Insights scientists deliver over 16 presentations at the Society of Toxicology’s 65th Annual Meeting and ToxExpo in San Diego starting March 23, 2026. • Key posters cover topics like PFAS exposure disrupting melanin synthesis in melanocytes, inhalation risks from 3D printing resins in dentistry, and thyroid hormone disruption using new approach methodologies. • Findings aim to provide decision-ready evidence on chemical health risks, as stated by VP Russell Thomas: 'Generating practical, decision-ready evidence about chemical exposures and health risks.'

• Common PFAS 'forever chemicals' exposure linked to reduced bone density in children, potentially causing lifelong skeletal weakness. • Peer-reviewed study from The Endocrine Society shows early-life contamination disrupts bone development before adulthood. • Prevalent in U.S. water supplies and consumer products, PFAS affect 99% of Americans, raising public health alarms per CDC data.

Exclusive: Testing in Bentham, home to UK’s highest recorded Pfas levels, finds one in four have blood levels in greatest risk categoryAlarming levels of toxic forever chemicals have been found in the blood of people living in a town previously revealed to be contaminated with the UK’s highest recorded level of Pfas.Pfas, short for per- and polyfluoroalkyl substances and commonly known as forever chemicals because of their persistence in the environment, have been linked to a wide range of serious illnesses, including some cancers. They are used in a variety of consumer products but one of their most prolific uses is in firefighting foam. Continue reading...

• The EPA issued a final rule on February 27, 2026, adding sodium perfluorohexanesulfonate (PFHxS-Na) to the list of chemicals subject to toxic chemical release reporting under the Emergency Planning and Community Right-to-Know Act. • The rule implements a mandate from the National Defense Authorization Act for Fiscal Year 2020 and requires reporting for chemicals subject to the Pollution Prevention Act beginning with reporting year 2026. • The final rule becomes effective March 30, 2026, and the EPA determined notice-and-comment rulemaking was unnecessary as the action conforms regulations to Congressional legislative mandate.

• A new study finds that exposure to PFAS (per- and polyfluoroalkyl substances)—chemicals used in non-stick coatings and water-resistant products—is linked to low bone density in teenagers. • The research, announced by the Endocrine Society, involved collaboration between the CDC, University of Cincinnati College of Medicine, University of Pennsylvania, Simon Fraser University, and George Washington University. • The finding adds to growing evidence that PFAS contamination poses significant health risks, particularly during critical periods of skeletal development in adolescence.

If costs stay high for the next three months, US owner Peter Huntsman says he will close the site on TeessideThe American owner of one of Britain’s last major chemicals plants has said he will close the site if energy prices remain at their current levels for the next three months.Peter Huntsman, whose family built Huntsman Corporation into a global chemicals empire, said the recent jump in gas prices fuelled by the Iran conflict was “another nail in the coffin” for European heavy industry.

US test of 120 umbilical blood cord samples identified 42 Pfas compounds, which do not naturally break downSign up for the Breaking News US email to get newsletter alerts in your inboxNew peer-reviewed research shows fetuses likely have much higher levels of Pfas “forever chemicals” in their blood than previously thought.Testing of umbilical cord blood typically looks for a small number of common Pfas compounds, like Pfoa and Pfos. However, thousands of Pfas exist, and a new Mount Sinai study tested 120 umbilical blood cord samples that were previously found to contain up to four compounds. Continue reading...
