A radon in drinking water interlaboratory comparison (ILC) was conducted between eight laboratories in Europe. The majority of the measurement results submitted were in agreement with the assigned value, with a single result deemed questionable. The questionable result does not deviate significantly from the assigned value but the measurement uncertainties associated with this result could be too small. The results from this ILC indicate that there is good agreement between participating laboratories for radon in water measurements.

Human Aichi virus 1 (AiV-1) is a water- and food-borne infection-associated picornavirus that causes gastroenteritis in humans. Recent studies on environmental waters showed a high frequency and abundance of AiV-1, suggesting that it might be an appropriate indicator of fecal contamination. We screened 450 surface and drinking water samples from a Tunisian drinking water treatment plant (DWTP) and the Sidi Salem dam for AiV-1 by real time reverse transcriptase PCR (RT-qPCR).

Alum shale formations in Scandinavia are generally enriched in uranium (U) and, when exposed to air and water, may produce acidic rock drainage (ARD), releasing potentially harmful elements into the environment. Taraldrud is a legacy site in southeast Norway where approx. 51 000 m of alum shale was deposited in the 1980s-1990s.

Dichloroacetic acid (DCAA), trichloroacetic acid (TCAA), and bromate (BrO) are disinfection byproducts (DBPs) formed during drinking water treatment and pose health risks. Rapid and reliable detection of these DBPs is essential for ensuring water safety. Non-suppressed ion chromatography (IC)-electrospray ionization mass spectrometry (IC-ESI-MS/MS) offers a promising approach for simultaneous analysis of organic haloacetic acids (HAAs) and inorganic oxyhalides, but previous methods using toxic methylamine can pose health risks.

Behavioral copying is a key process in group actions, but it is challenging for individuals with autism spectrum disorder (ASD). We investigated behavioral contagion, or instinctual replication of behaviors, in Krushinky-Molodkina (KM) rats ( = 16), a new potential rodent model for ASD, compared to control Wistar rats ( = 15). A randomly chosen healthy Wistar male ("demonstrator rat") was introduced to the homecage of experimental rats ("observers") 10-14 days before the experiments to become a member of the group.

Background: Given the lack of models for carotid artery dissections (CAD), we aim to investigate effects of beta-aminopropionitrile (BAPN) combined with physical damage on the arterial walls of rats, and to establish a high-incidence and low-mortality CAD model.
Methods: Sixteen SPF SD rats (3-week-old) were divided into two groups. Group B was given 0.
