Polychlorinated biphenyls (PCBs) are toxic chemicals once widely used in industrial products. They were later banned because they cause serious environmental and health harm. While most research has focused on these “legacy” PCBs, this study highlights by-product PCBs that form unintentionally during modern manufacturing. The authors estimate that current U.S. regulations allow the production of even more of these by-product PCBs than during peak use in the 1970s. These PCBs are not routinely monitored, so they may go largely undetected in the environment. The findings suggest that PCBs should be seen as an ongoing and potentially growing environmental concern.
Is Current Generation of Polychlorinated Biphenyls Exceeding Peak Production of the 1970s?
This article from MADE SAFE explores the hidden environmental impacts of so-called “disappearing plastics.” Products such as laundry and detergent pods often use a material called polyvinyl alcohol, which is designed to dissolve in water. However, the article explains that dissolving does not necessarily mean the material disappears completely. It examines what happens to these plastics after use and discusses concerns about their potential contribution to microplastic pollution. The article encourages readers to take a closer look at everyday convenience products and consider their long-term environmental impacts.
Plastic pollution continues to accumulate in the world’s oceans, but scientists are still learning where it gathers and why. In this study by Environmental Science and Technology, researchers collected plastic debris from the North Pacific Ocean. They found high concentrations not only in the well-known North Pacific Garbage Patch but also in a second unexpected hotspot. Most of the plastic consisted of polyethylene and polypropylene, two of the most common plastics used in everyday products. The findings suggest that ocean currents alone cannot explain how plastic accumulates at sea and highlight the need for further research to better understand marine plastic pollution.
New research from CSIRO, an Australian national science agency, and the University of Toronto estimate that up to 11 million tonnes of plastic pollution are sitting on the ocean floor. They discovered that the ocean floor has become a resting place, or reservoir for plastic debris. With plastic use predicted to double by 2040, understanding how and where it travels is crucial to protecting marine ecosystems and wildlife.
This article examines the challenges of managing waste after the devastating February 2023 earthquakes in Turkey. Collapsed and damaged buildings produced large amounts of debris that can contain hazardous materials such as asbestos and heavy metals. If not handled safely, this debris can harm both human health and the environment. In many cases, waste management after the disaster was poorly coordinated, with waste transported and stored close to communities and sensitive ecosystems. This highlights the need for safer and more organized systems to reduce environmental damage and protect public health during recovery.
Synthetic textiles release a type of microplastic called microfibers throughout their lifetime, contributing to environmental pollution and potential health risks. This review examines where microfibers come from, how they are released and how they spread through air and water systems. These fibres can also carry other pollutants that have been linked to harmful biological effects. Microfibers have been found in humans and natural ecosystems, raising concerns about how widespread exposure may be. The study highlights that reducing microfiber pollution will require a combined approach, including improved wastewater treatment, changes in textile production and stronger policies.
