UV absorbents and industrial antioxidants can reach aquatic environments through the degradation of plastics, or via wastewater treatment plant effluents.

UV absorbents and industrial antioxidants are used in many household goods to protect them from UV radiation. They can have an adverse impact on ecosystems.
How long do we really need chemicals to last?

PFAS can be filtered, but getting rid of the chemicals is a monumental challenge. A new breakthrough offers some hope.
Maywood Riverfront Park was built on the site of eight former industrial properties in Los Angeles County.

Climate change is colliding with old factory sites where soil or water contamination still exist, and the most vulnerable populations are particularly at risk.
PFAS, often used in water-resistant gear, also find their way into drinking water and human bodies.

The federal government has new advisories on PFAS, which can put human health at risk in a list of ways, but so far only states are regulating the chemicals.
Stain-resistance can mean questionable chemicals in children’s clothes.

Tests found PFAS in school uniforms, pillows, upholstered furniture and several other items that are often next to children’s skin and near their noses and mouths.

Farmers are stuck in a chemical war against weeds, which have developed resistance to many widely used herbicides. Seed companies’ answer – using more varied herbicides – is causing new problems.
Scientist Michelle Murphy says we should ‘value wastelands …and injured life.’ Here, collected plastic from the shoreline of Hamilton, Ontario is sorted by colour.
In this episode, two Indigenous scientists running collaborative labs to address our climate crisis offer some ideas for environmental justice, including a redefinition of pollution.
Chlorpyrifos is widely used on crops, including fruits, vegetables, nuts, corn and soybeans.

What kind of evidence does it require to get a widely used chemical banned? A professor of medicine and former state regulator explains how the case for chlorpyrifos as a threat to public health developed.

We can fine-tune bacteria using algorithms to help them produce the things we need, from antibiotics to methane.
Paraquat’s potentially lethal effects on humans are well known. But our research has found it also causes serious environmental damage.
Phthalates can be found in many common products and types of plastic packaging.

Scientists issued an urgent call for better federal regulation of these endocrine-disrupting chemicals. Here’s what you can do to reduce your family’s risk.

Small, practical messaging campaigns on pesticide toxicity can lead farmers to choose safer, less-toxic pesticides.

To understand the risks of wildfire smoke, it helps to understand the chemicals people are breathing.

Two environmental engineers say governments need to do more to protect people from possible water contamination after wildfires.
The same chronic illnesses associated with exposure to endocrine-disrupting compounds also increase risk of developing severe COVID-19.

Endocrine-disrupting compounds are pervasive in modern life, from food packaging to shampoo. Research is connecting their effects on humans to risk of severe illness or death from the coronavirus.

A storm-driven chlorine gas release in a vulnerable community is the type of worst-case scenario that scientists and engineers have warned about for decades.
For combustion to occur, oxygen must be present. Ammonium nitrate prills provide a much more concentrated supply of oxygen than the air around us.
The 2018 Camp Fire north of Sacramento burned everything in its path: cars, power lines, and buildings – and contaminated local drinking water.

Buildings aren’t the only things at risk in wildfires. Recent disasters in California have left local water system contaminated with toxic chemicals afterward, slowing return and recovery.
Pepper spray uses a chemical called capsaicin. It’s the same compound that makes chillies hot, but in a more intense, weaponised form.
Phosphorus was first discovered by boiling down thousands of litres of urine.
We need phosphorus for life, as well as for fertiliser to help plants grow, but raw supplies are limited.
