Summary: This study investigated the contamination behavior of stainless steel 304L under the exposure of simulated high-level liquid waste (SHLLW). It was found that passivation occurred on the stainless steel surface during exposure, and the deposition of certain elements was also observed. These findings are important for designing corrosion inhibitors, decontamination agents, and improved reactor materials.

Summary: The occurrence of PAHs in agri-food commodities has raised safety concerns, especially as evidence suggests that edible oil-yielding seeds are often contaminated. PAHs, which can enter the human food chain through edible oils, are currently controlled primarily through production process optimization but with limited specificity. The levels of PAH contamination vary in different edible oils depending on their type, production process, and storage conditions. This overview provides a comprehensive assessment of PAH incidence, sources, and decontamination methods in edible oils, aiming to bridge information gaps and promote a green and sustainable approach to remediate PAH-contaminated plant-based oils.

Summary: The study found that the type of smear media used affects tritium collection efficiency, with porous smear materials leading to an increase in measured tritium activity over time. Both water-wetted cotton swabs and paper smears showed significant time dependence in measured activity, with cotton swabs also exhibiting reduced collection efficiency.

Summary: This study utilizes Computational Fluid Dynamics (CFD) modeling to investigate the physical decontamination methods of contaminated pipes in nuclear power plants, focusing on the mechanisms of abrasion and erosion. The study examines the effects of fluid and solid particle properties, particle size, and velocity on erosion, and compares the obtained results for a particular pipe diameter and size based on maximum erosion rate values.

Summary: A decontamination study was conducted on iodine-131 contamination using Ce (IV)/HNO3 as a decontamination agent for metal surfaces. The study examined the effects of nitric acid concentration, Ce (IV) concentration, temperature, and decontamination time on the decontamination factors of brass and aluminum. The maximum decontamination factor observed was 5.80 for brass, with temperature having a greater influence than Ce (IV) concentration, decontamination time, and nitric acid concentration. For aluminum, the maximum decontamination factor was 319.49, with Ce (IV) concentration having a greater influence than decontamination time, nitric acid concentration, and temperature.

Summary: Pig hair, modified using ammonium thioglycolate, shows increased capacity to capture Hg(II) and selectively sequester it from water with coexisting metal ions. Moreover, the modified pig hair reduces the phytotoxicity of mercury in water spinach, providing a sustainable solution for waste utilization.

Summary: This paper reviews the contamination of aflatoxins, zearalenone, deoxynivalenol, fumonisins, and ochratoxin A in major cereals (rice, wheat, and maize) in China. Based on 8700 samples from 30 provincial areas, previous research suggests that the temperature and humidity in the highly contaminated Chinese cereal-growing regions match the growth conditions of potential antagonists. Therefore, the paper summarizes the methods of microbial detoxification, microbial active substance detoxification, and other microbial inhibition methods for treating contaminated cereals, and proposes strategies for combining these methods with the treatment of contaminated cereals in China.

Summary: Hair cortisol concentration (HCC) is used as an indicator of long-term stress or pathologies. However, contamination can lead to the incorporation of external cortisol, affecting the HCC results. This study investigated the effects of urine contamination on HCC in different hair segments of pigs and cattle, and found that contamination generally increased HCCs, with a greater impact on distal hair segments. Therefore, it is important to avoid contamination when collecting hair samples for HCC analysis, and preferably use proximal hair segments.

Summary: Beach sand can harbor potential human pathogens, posing a threat to public health. However, the monitoring of sand microbiome is rarely conducted to assess beach quality. This study analyzed the microbial population of a Northern Adriatic Sea beach sand, finding the presence of drug-resistant strains and suggesting quicklime as a possible method to decontaminate sand.

Summary: The study aimed to compare the effectiveness of conventional (chlorinated alkaline) and alternative (chlorinated alkaline plus enzymatic) treatments in eliminating biofilms from different strains of L. monocytogenes. It also evaluated the cross-contamination to chicken broth from non-treated and treated biofilms on stainless steel surfaces. The results showed that changing to more intense cleaning treatments, such as the alternative treatment, can reduce the risk of cross-contamination.

Summary: In the last decade, fresh-cut plants have become a popular food flavoring additive. This study evaluated the effectiveness of ozonated water in improving the microbial safety of fresh-cut parsley leaves. The results showed that ozone treatment can effectively enhance the microbiological safety of parsley leaves.

Summary: This study developed a Python-based pipeline named CleanSeq, which automatically detects and removes contaminated reads, and analyzes possible genome variants with proper verifications via local re-alignments. The application and reproducibility of CleanSeq were demonstrated in simulated and experimental evolution genome sequencing data.
