Coal combustion by-products (CCPs) (i.e. fly (FA) and bottom (BA) ashes) generated by power plants contain heavy metals. This research presents leaching properties of coal ashes (FA and BA) collected from Jimah coal-fired power station, Port Dickson, Negeri Sembilan using USEPA standard methods namely toxicity characteristic leaching procedure (TCLP), and synthetic precipitation leaching procedure (SPLP). Heavy metals like lead (Pb), zinc (Zn), copper (Cu) and arsenic (As) were quantified using atomic absorption spectrometer (AAS). The leached of heavy metals fluxes were Cu < Zn < Pb < As. As leached the most whilst indicating of possible contamination from As. Overall, the ranges of leached concentration were adhered to permissible limits of hazardous waste criteria for metal (Pb and As) and industrial effluent (Zn and Cu). The presented data has potential reuse as reference for the coal ash concrete mixed design application in construction industries.

In this study, we evaluated the antibacterial activities of plant essential oils (EOs) from the Lamiaceae family against Agrobacterium tumefaciens to find new eco-friendly antimicrobials. Thymus vulgaris L. (thyme white) EO demonstrated the most potent fumigant antibacterial activity among these.

As key pollinators, bees are increasingly threatened by environmental stressors such as heavy metals, pesticides, and temperature fluctuations, which can cause oxidative stress and disrupt cellular homeostasis. Glutathione S-transferases (GSTs) play crucial roles in antioxidant defense and detoxification, yet systematic studies on bee GST families remain limited. Here, we conducted a genome-wide analysis of cytosolic GST genes in 13 bee species, identifying 146 genes in total.

Background: Zinc (Zn) and cadmium (Cd) ions are ubiquitous in industrial and daily life. Despite their critical impact on food safety and human health, current probes face significant limitations in simultaneously detecting both ions in complex food matrices.
Results: Herein, we successfully developed a pyrene-based FRET ratiometric fluorescent probe QP for the highly selective detection of Zn and Cd.

Background: Previous studies involving cleanup via conventional solid-phase extraction (SPE) materials to overcome matrix effects for the polar organophosphonate and -phosphinate pesticides glyphosate, glufosinate, ethephon, fosetyl, and their various metabolites often showed limitations due to the existence of various matrix compounds in plant commodities with similar polarity. To overcome existing drawbacks, we utilized the unique selectivity provided by metal oxides as SPE materials. These were exploited in a novel automated online SPE-LC-MS/MS method which allowed analyte-specific trapping in the presence of excessive amounts of matrix compounds as typically contained in extracts of the Quick Polar Pesticides (QuPPe) method.
