Invasive silver carp () threaten Mississippi River basin ecosystems due to their ability to outcompete native species. Stable carbon (δC) and nitrogen (δN) isotope analysis has been used to study how silver carp impact native ecosystems, but lipids in fish tissues commonly bias their δC values. Chemical lipid extraction and mathematical equations that normalise δC values for lipid content can account for this bias, but have not been assessed for silver carp.

The contamination of Alternaria toxins poses a potential risk to human health. This study developed a rapid, efficient, and environmentally friendly method for the simultaneous determination of five types of Alternaria toxins in wheat using high-precision and stable isotope liquid chromatography tandem mass spectrometry. The comparison between dilution method and solid-phase extraction method shows that the former achieves satisfactory results with a simple and convenient sample purification method.

Introduction: Mineral trioxide aggregate (MTA) is a calcium silicate-based cement that has changed conventional dental therapeutic approaches. This study aimed to evaluate physical, chemical and biological properties of novel AGM MTA, in comparison with MTA Angelus.
Methods: The samples were prepared according to the manufacturer's instructions.
Fuzzy logic modelling of the pollution pattern of potentially toxic elements and naturally occurring radionuclide materials in quarry sites in Ogun State, Nigeria.

The accumulation pattern of some inorganic pollutants in quarry sites around Ogun State was modeled using a Fuzzy comprehensive assessment (FCA). Potentially toxic elements (PTEs) and naturally occurring radionuclides materials (NORMs) were assessed from soil samples collected from ten quarry sites in three districts (Odeda, Ajebo, and Ijebu Ode) in Ogun State. Three (3) NORMs ( K, U, Th) were assessed using gamma spectrometer with a NaI detector while ten (10) PTEs (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were determined by digestion method using Inductively coupled plasma optical emission spectrophotometer.

Understanding cadmium (Cd) pathways in cacao trees is critical for developing Cd mitigation strategies. This study investigates whether Cd uptake and translocation mechanisms differ between a low and a high Cd-accumulating cacao cultivar. We sampled three replicate trees of each cultivar, and a grafted cultivar that shared the same scion as the low Cd accumulator but had a different rootstock.
