"What surprised me is we are still seeing so many visits to emergency departments associated with very common household cleaning products," Lara McKenzie, Ph.D., stated, emphasizing the ongoing issue despite safety advancements.

In 2019, scientists found that balloons eaten by seabirds are more likely to kill them than other kinds of plastic yet they do not seem to have been earmarked in the same way as, for example, plastic straws.

We were $16,000 out of pocket, with weekly blood work, invasive ultrasounds, sperm quality testing, genetic testing, eating well, exercising, daily cold plunging, expensive vitamins, excessive pregnancy testing and more tears than I would like to remember. We were at a loss, with an official diagnosis of unexplained infertility.

Plasticizers are a general term for a whole range of chemicals added to materials, typically plastic and rubber, to make them softer and more pliable. They're found in countless everyday items like plastic shower curtains, shrink-wrap, PVC raincoats or flexible tubing and wire insulation for homes. Plasticizers, sometimes called phthalates, are also found in cosmetics, like nail polishes, lotions and shampoos.

Environmental monitoring has traditionally relied on snapshots of exposure from a water sample collected on a single day, a blood sample drawn at one point in time, or soil tested from a specific location. But exposure unfolds gradually as people move through different environments and come into contact with air, dust, and surfaces throughout the day.

Crude oil is a complex mixture of hydrocarbons - molecules made mainly of carbon and hydrogen. Refineries and chemical plants separate and transform these molecules into smaller chemical building blocks known as petrochemicals. Some of the most important petrochemical building blocks include chemicals such as ethylene, propylene and benzene.

Exposure to a fungicide induced changes to gene expression in rats that persisted for at least 20 generations. It also increased the chance of offspring developing kidney disease, obesity or experiencing complications when giving birth, according to the longest-running study of 'epigenetic' changes in mammals.

Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures. It found global heating accelerated from a steady rate of less than 0.2C per decade between 1970 and 2015 to about 0.35C per decade over the past 10 years.

Never place batteries of any type in your curbside recycling bin. Batteries can damage recycling equipment and, if lithium batteries are mixed in, cause fires. Always use designated battery collection programs.

This corn-based construction material was made by Manufactura, a Mexican sustainable materials company, and it imagines a second life for waste from the most widely produced grain in the world. The project started as an invitation by chef Jorge Armando, the founder of catering brand Taco Kween Berlin, to find ways he could reintegrate waste generated by his taqueria into architecture. A team led by designer Dinorah Schulte created corncretl during a residency last year in Massa Lombarda, Italy.

Your eyes don't deceive you. The use of polyester has ballooned with time, according to Henry Navarro Delgado, an associate professor at Toronto Metropolitan University's school of fashion. It's partly because polyester can be quite useful, he said. It is a type of plastic made from petroleum compounds that are cooled and stretched into yarn, according to Michael Palladino, a fashion industry veteran and lecturer at Kingsborough Community College's business of fashion program in New York.

In 2021, amid the COVID‑19 pandemic, Kristin Wall became pregnant with her second child. Her physician told her that little was known about the COVID-19 vaccine's safety and effectiveness in pregnant people. Observational data - collected from those vaccinated before they knew that they were pregnant - suggested that the vaccine was safe, so she could have it. Still, she'd have to weigh up the risks and benefits herself.

More research is needed, however, for government agencies to determine whether the chemical levels found in these products requires greater regulation, the study authors say. The hazardous chemicals we identified each carry their own risks, says Elissia T. Franklin, lead author of the new paper and a research scientist at the nonprofit research organization Silent Spring Institute. Our findings showed that these products can expose [people] to multiple chemicals over time, and through repeated use, these combined exposures add up.

Many human activities - from improper disposal of waste to the degradation of car tyres - release small plastic particles, which have infiltrated the atmosphere, oceans and other ecosystems. These include nanoplastics - particles measuring less than 1 micrometre across - and microplastics, which range from 1 micrometre to around 5 millimetres. They've entered our bodies and brains, and scientists are still working to understand their effects on people's health.

The household burning of plastic for heating and cooking is widespread in developing countries, suggests a global study that raises concerns about its health and environmental impacts. The research, published in the journal Nature Communications, surveyed more than 1,000 respondents across 26 countries. One in three people reported being aware of households burning plastic, while 16% said they had burned plastic themselves.

Black plastic gets its color from carbon black pigment and is commonly used in food containers, such as meat or produce trays and take-out containers, as well as disposable coffee lids, plastic bags, and hard plastic items like DVD cases and planters. While plastic is one of the categories of things that we are encouraged to recycle - when we can't reuse or repurpose it - not all black plastic items can be recycled.

They write, 'through clever processing changes, this material is now stronger, more beautiful, and available in higher volumes at a lower price point.' The design remains the same with the frosted look, and this time, it can carry loads better but still lasts only as long as it's needed. After use, the bags can be placed in home compost or industrial compost systems, where they break down into healthy soil.

Europe's supermarket shelves are packed with brands billing their plastic packaging as sustainable, but often only a fraction of the materials are truly recovered from waste, with the rest made from petroleum. Brands using plastic packaging from Kraft's Heinz Beanz to Mondelez's Philadelphia use materials made by the plastic manufacturing arm of the oil company Saudi Aramco. The Saudi state-owned holding opposes production cuts under the UN plastic treaty and is the world's largest corporate greenhouse-gas emitter (over 70m tonnes up to 2023).

According to research by the World Economic Forum and United Nations Development Programme, the circular economy could unlock $4.5 trillion in new global value by 2030, and investors are racing to capture part of that opportunity. Meet Elizabeth Blankenship-Singh, Director of Innovation at Overlay Capital, an Atlanta-based alternative investment firm whose Waste and Materials Fund is backing both early-stage materials innovators and later-stage recycling operations with established infrastructure.
