Direct, rapid, non-destructive and 'white' multielemental toxicological analysis of hazardous elements with health risk assessment in candies and wrappers from Polish flea markets using portable XRF spectroscopy.

Elemental analysis of solid candy and wrapper samples from Polish flea markets was conducted using portable X-ray fluorescence (pXRF), a fast, cost-effective, and non-destructive technique. Hazardous elements were detected in candies, including Ni (5.20 ± 0.

Carbon Nanotubes in Cement-A New Approach for Building Composites and Its Influence on Environmental Effect of Material.

An addition of carbon nanostructures to cement paste is problematic due to the difficulties in obtaining homogenous mixtures. The paper reports on a more effective way of mixing carboxylated multi-walled carbon nanotubes (MWCNT-COOH) in cement pastes. The additional biological impact of the studied nanomodified cement was analyzed in the case of two moss species' vitality.

Prediction of key toxicity endpoints of AP-238 a new psychoactive substance for clinical toxicology and forensic purposes using in silico methods.

This study performed advanced toxicological assessments of the new substance AP-238 using nine 'green' in silico methods, focusing on acute toxicity, organ-specific effects, skin and eye irritation, genetic toxicity, and cardiotoxicity. A quantitative assessment of AP-238's acute toxicity (AT) was performed by predicting theoretical LD values for both rats and mice across different administration routes using various in silico methods. Results indicated the highest toxicity via intravenous administration in mice, with a t-LD of 53 mg/kg, while oral administration in rats exhibited a lower toxicity range, with t-LD values between 666.

Antioxidant activity of new strawberry clones: June-bearing and ever-bearing.

Strawberry is one of the most commonly eaten berries. Breeding procedures led to the separation of two types of strawberries: June - bearing and Ever-bearing strawberries fruit for about a month and Ever - bearing throughout the growing season. The aim of the project is to compare the antioxidant parameters between both types of strawberries with those of two other dicots (blackberry and red raspberry).

The toxicological analysis of problematic and sophisticated elements (Ni, Cr, and Se) in Food for Special Medical Purposes (FSMP) using in pharmacotherapy and clinical nutrition for oncological patients available in Polish pharmacies.

This study focuses on FSMPs for oncologic patients, specifically analyzing the toxicological profiles of nickel (Ni), chromium (Cr), and selenium (Se) within these products available in Polish pharmacies. The presence of these elements was quantified using inductively coupled plasma mass spectrometry (ICP-MS). Results indicated variations in the concentrations of Ni, Cr, and Se across different FSMP samples, with some products exceeding the acceptable limits set by regulatory guidelines.
