The concern of potential toxic elements (PTEs) contamination in the river ecosystem is growing due to anthropological activity. The contents of seven PTEs in sediments from the Balu River channel were analyzed using atomic absorption spectroscopy (AAS) and an environmental risk model. Several PTEs were found in the sediment at high levels, including zinc (Zn), copper (Cu), arsenic (As), lead (Pb), cadmium (Cd), nickel (Ni), and mercury (Hg), that might pose a risk to human and ecological health.

Prenatal exposure to heavy metals poses risks to fetal brain development, yet the joint effects of these metals remain unclear, with inconsistent findings across statistical models. This study investigates the joint effect of prenatal exposure to cadmium (Cd), nickel (Ni), mercury (Hg), and lead (Pb) on infant neurodevelopment using various statistical approaches. The study included 400 mother-infant pairs.

Emerging mercury-free ultraviolet (UV) sources, such as krypton chloride excimer (KrCl*) lamps and UV light emitting diodes (UV-LEDs), emit diverse wavelengths with distinct inactivation mechanisms. The combined application has the potential to improve disinfection effectiveness through synergism. In this study, a mini-fluidic photoreaction system equipped with a KrCl* lamp (222 nm) and a strip of UV-LEDs (275 nm) was developed, which could individually/simultaneously deliver accurate UV radiation(s) at 222 nm (0.

In marine ecosystems, arsenic (As) and total mercury (T-Hg) represent two of the major pollutants, particularly in fish due to their ecology and the affinity of these metal(loid)s with biological cycles. This study assessed the influence of total length, total weight, relative condition factor, and trophic levels of ten marine fish species from the Colombian Caribbean on As and T-Hg accumulation in muscle tissue, as well as the differentiation in accumulated amounts based on fish habitat type. In this context, Balistes capriscus exhibited the highest As median (7949.

Purpose: Heavy metals, which are persistent in the environment and toxic, can accumulate in the body and cause organ damage, which may further negatively affect perinatal women and their fetuses. Therefore, this systematic review was conducted to evaluate the effectiveness of dietary interventions to reduce heavy metal exposure in antepartum and postpartum women.
Methods: We searched five databases (PubMed, Embase, Scopus, Web of Science, and Cochrane Library) for randomized controlled trials that provided dietary interventions for antepartum and postpartum women.
