Summary: This study presents two complementary approaches to account for shading in algal growth inhibition tests of engineered nanomaterials (ENMs) and colored substances. The first approach distinguishes between shading effects and toxicity, while the second approach addresses shading at the cellular level. The results indicate that toxicity rather than cellular shading dominates the response of algae exposed to ENMs.

Summary: A sulfur dioxide concentration detector for daylily food safety applications is proposed in this study. The detector converts sulfur dioxide concentration in daylily solution into output time period in a linear manner. It is capable of quickly and conveniently measuring the sulfur dioxide concentration in daylily solution. Experimental results demonstrate that the proposed detector functions normally for daylily food safety applications.

Summary: Edible films made from carboxymethyl cellulose (CMC)/starch incorporated with titanium dioxide (TiO2) nanoparticles were developed and characterized in terms of various properties. The results showed that the irradiation dose and TiO2 content affected the thermal stability, mechanical properties, and antimicrobial activity of the films. The irradiated CMC/starch/TiO2 film demonstrated prolonged shelf life for strawberries. These edible films have the potential for application in active food packaging.

Summary: Food waste is increasingly scrutinized due to the projected need to feed nine billion people in 2050. Food recovery, as a practice to prevent surplus food from being landfill disposed, faces challenges in terms of food safety and technical regulation. More research is needed to address the barriers to implementing innovative food recovery practices in US foodservice settings, including insufficient data and unclear regulatory guidelines.

Summary: Packaging plays a vital role in preserving the properties of food and preventing food spoilage caused by microorganisms. Combining chitosan and metallic nanoparticles can be a practical approach in antimicrobial packaging systems, offering benefits such as thermal stability and extended shelf life of food products.

Summary: This study analyzed the concentration of potentially toxic elements in farmed fallow deer antlers and found that the position in the antler and age of the animal influenced the element concentration. The age of the animal was positively correlated with the accumulation of certain elements, while body mass and antler mass were negatively correlated with other elements. Additionally, the concentration of toxic elements in the feed varied with the season.

Summary: This article presents the history of titanium dioxide usage, discusses health concerns regarding its use as a food additive, and explores the evolution of regulations related to TiO2 in different periods. The specific roles played by stakeholders are highlighted, along with the shift in regulatory approaches towards nanotechnology in the context of food safety governance. Academic research signaling, along with civil society advocacy for precautionary principles, are seen as influential factors in regulatory decision-making.

Summary: PI fine particles encapsulating a large number of TiO2 nanoparticles were successfully fabricated using the emulsion re-precipitation method in a multistep flow synthetic system. The fabricated material had a spherical structure with TiO2 nanoparticles disproportionately embedded near the surface, showing high UV shielding efficiency according to UV-vis transmission spectra.

Summary: This study isolated microplastics from soils collected from the Kavir and Lut Deserts on the Iranian plateau, with most of them having a fibrous nature and being composed of polyethylene terephthalate and Nylon. The majority of microplastics are likely brought into these desert environments from distant sources via wind, undergoing rapid transport, internal recycling, as well as significant photo-oxidation and mechanical weathering.

Summary: Plastics from beaches of different lakes in Switzerland were found to contain potentially hazardous chemical elements. These elements mainly exist as additives, including pigments, stabilizers, and flame retardants. Comparing data from different lakes helps to understand the persistence of plastics in lakes and propose effective management schemes.

Summary: This study investigates the tissue-specific bioaccumulation, release, and genotoxic response of tritiated stainless steel particles in marine mussels. The study finds that the particles rapidly accumulate in the mussel tissues, especially in the digestive gland, but are readily rejected and expelled over longer periods of time. The absence of genotoxicity suggests that the rapid processing of the particles and limited dissolution of steel components prevent chemical toxicity effects.

Summary: Abandoned boats are a growing problem in the coastal zone and have received limited attention. This study utilized Google Earth to remotely identify and gather information on abandoned boats in southern England. The survey revealed the presence of 266 abandoned boats mainly located in intertidal zones. The majority of these boats were made of timber and showed signs of damage and water-sediment ingression. The environmental impacts are expected to be significant, especially where clustered on protected mudflats.

Summary: This study investigated the presence and concentrations of lead (Pb) and chromium (Cr) in road paints from 236 samples collected from various locations in eleven European countries. The results showed high concentrations of Pb and Cr, with the presence of other lead-based pigments in some paints. Despite significant international differences, road paints containing Pb and Cr remain a pervasive environmental problem and potential health risk in European countries.
