Pressure from trade agreements can clean up sources of environmental harm, leading to cleaner rivers in the case of Mexico’s much-loved avocados.
When you breathe in wildfire smoke, harmful particles can travel deep into your body.
As the national conversation shifts to political finger-pointing, an important environmental question deserves careful scrutiny: What is the best approach to maintain urban water quality?
Mice numbers are likely to drop as winter sets in – an expert explains.
The risk to firefighters isn’t just from breathing wildfire smoke – it’s also in the chemicals that get on their clothes and filter through to their skin.
New research offers a cautionary tale about the difficulty of removing ‘forever chemicals’ from the environment.
The move reshapes how future assessments of chemical dangers will be carried out, and if they’ll be ignored, delayed or understated to benefit industry.
Cancer-linked chemicals can remain hidden in drinking water supplies for decades.
Petrochemicals derived from oil and fossil fuels underlie the production of many consumer goods − and many you wouldn’t know from looking at the final product.
Farming areas that use lots of fertilizers and pesticides stood out for the swift and accelerating decline of their bird populations.
A whistleblower has raised safety concerns about working inside Porton Down, which has a long history of conducting dangerous biochemical research.
Some of these ‘forever chemicals’ are toxic at very low levels. They can get into water systems and bioaccumulate in fish, ultimately posing risks to people.
An atmospheric chemist offers quick, easy and inexpensive suggestions to reduce indoor air pollution.
When cities burn, plastics, electronics, cleaning chemicals and much more create a toxic brew. Studies launched during the LA fires a year ago show exposure is often strongest inside homes.
An innovative study mapped preterm births, low birth weights and infant mortality to municipal water wells downstream from PFAS-contaminated sites. The results show the high cost of PFAS harm.
A recent survey of environmental toxicologists has revealed that they believe that chemical pollution can and is affecting the health of humans and wildlife.
Because of the federal government shutdown and proposed budget, key federal investigations may stop, including into what happened at a Chevron refinery in California in October 2025.
When a corpse flower bloomed on campus, atmospheric scientists got to work. What they discovered provides new evidence about the unique pollination strategies of a very unusual flower.
PFAS exposure can vary significantly from one community to the next. A close-up view of three Great Lakes states offers some insights for everyone.
