A pseudo-outbreak of bronchoscopy-associated and was traced to contaminated ice machine water and ice. A nonsterile ice bath was used to cool uncapped, sterile, saline syringes used to slow procedural bleeding. Joining the growing evidence of bronchoscopy pseudo-outbreaks, our investigation describes several lessons for future prevention.

Background: Human consumption of dairy products contaminated with aflatoxin (AF) M1 can lead to severe health issues. This AF's significance and impact on health necessitate a thorough investigation of its prevalence in dairy products.
Objectives: This study aims to determine the prevalence of AFM1 in dairy products through a systematic review and meta-analysis, focusing on data from Middle Eastern countries.

Mercury (Hg) contamination poses a persistent threat to the remote Arctic ecosystem, yet the mechanisms driving the pronounced summer rebound of atmospheric gaseous elemental Hg (Hg) and its subsequent fate remain unclear due to limitations in large-scale seasonal studies. Here, we use an integrated atmosphere-land-sea-ice-ocean model to simulate Hg cycling in the Arctic comprehensively. Our results indicate that oceanic evasion is the dominant source (~80%) of the summer Hg rebound, particularly driven by seawater Hg release facilitated by seasonal ice melt (~42%), with further contributions from anthropogenic deposition and terrestrial re-emissions.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of emerging contaminants that have been in use industrially since the 1940s. Their long-term and extensive commercial use has led to their ubiquitous presence in the environment. The ability to measure the bioconcentration and distribution of PFAS in the tissue of aquatic organisms helps elucidate the persistence of PFAS as well as environmental impacts.

High-energy electron beam exposure is generally recognized as the standard for achieving high-precision nanofabrication. Low-energy electron beam exposure techniques offer advantages in 3D manufacturing; however, they have received limited attention in traditional processes due to precision limitations and insufficient exposure, leading to an underestimation of their potential. In this article, we introduce a nanofabrication strategy using low-energy electrons in ice-assisted electron-beam lithography (iEBL) alleviating the compatibility issue between resolution and quasi-3D manufacturing.
