DYEING, PRINTING & FINISHING: PFAS – A Textile Perspective

May 19, 2021 (Courtesy of Consumer Reports) Despite the textile industry’s limited use of PFAS materials, future regulation may impact producers of performance fabrics. By Hardy Sullivan Given the wide array of end uses for per- and polyfluoroalkyl substances (PFAS), producers of performance fabrics, including personal protective equipment (PPE) gowns with superior blood repellency, workwear with oily stain release properties, and high-use upholstery needing resistance to oily foods and stains, might think the press’ portrayal of the textile industry misses the mark. Why focus on fabric but ignore phones? As an end-user of PFAS materials, textiles make up only a tiny fraction of PFAS consumption. And as a percentage by weight of fabric, a little goes a long way. Yet stain-resistant fabric gets top billing as a PFAS source in consumer-facing news articles. In turn, some state regulators have targeted PFAS-containing carpet and upholstery, detracting attention from primary pol

Shipping rule cleans the air but dirties the water

Share Some ships, such as this ferry off Corsica, keep their engines running in port, releasing both air and water pollutants.

A 2020 regulation aimed at cutting sulfur emissions from ship exhaust is prompting many owners to install scrubbing systems that capture pollutants in water and then dump some or all of the waste into the sea.

Earthworms could help reduce antibiotic resistance genes in soil

 E-Mail Earthworms improve the soil by aerating it, breaking down organic matter and mineralizing nutrients. Now, researchers reporting in ACS Environmental Science & Technology have dug up another possible role: reducing the number and relative abundance of antibiotic-resistance genes (ARGs) in soils from diverse ecosystems. These results imply that earthworms could be a natural, sustainable solution to addressing the global issue of antibiotic resistance, the researchers say. The overuse of antibiotics in humans and animals has caused ARGs to accumulate in soils, which could contribute to the rise in antibiotic-resistant infections. Earthworms consume tons of soil per year worldwide, and their guts have a unique combination of low-oxygen conditions, neutral pH and native microbial inhabitants that could have an effect on ARGs. However, the role of earthworms in the spread of antibiotic resistance has been controversial. Some studies in controlled settings suggest that their g
