Summary: This study focused on the concentrations and sources of metals in two important rivers in the Eastern Cape, South Africa. Most of the essential metals were within the guidelines for domestic water use, except for selenium and iron. Cadmium and lead concentrations exceeded the South African Water Quality Guidelines and World Health Organization limits. The wastewater treatment plant effluent and municipal dumpsite leachates were found to affect metal ion concentrations in the rivers.

Summary: The consumption of aphrodisiacs is common in South Africa, and determining the levels of trace metals in these products is important for protecting consumers' health. A study was conducted to assess the health risks posed by metals in aphrodisiacs collected from herbal markets in Johannesburg and Durban. The study found that while common metals were within safe limits, trace metals exceeded the limits, possibly due to tap water collected from dilapidated buildings. However, the overall health risk assessment showed minimal risks, indicating that these aphrodisiacs can be consumed without fear of metal contamination.

Summary: Biochar derived from macadamia nut shells (MHP) embedded with iron sulfide (FeS) nanoparticles was found to effectively adsorb and reduce Cr(VI) to Cr(III). The FeS nanoparticles were irregular in shape, as shown by scanning electron microscopy, and contained Fe, S, O, and C atoms. The maximum adsorption capacity for Cr(VI) was 4.95 mg/g at pH 3, 60 min, and 25°C, and the adsorption process followed the Langmuir and pseudo-second-order models. Thermodynamic calculations indicated that the remediation process was spontaneous and endothermic. With further optimization, this material could be a promising adsorbent and reductant for Cr(VI) in water.

Summary: In this study, supercritical fluid extraction (SFE) and CO2-expanded liquid extraction (CXLE) were used to extract lignin from softwood and hardwood chips. Ethanol, acetone, and ethyl lactate were investigated as green organic co-solvents in the extractions. The optimized method using liquid CO2/acetone/water (10/72/18, v/v/v), at 60°C, 350 bar, 30 min, and 2 mL/min flow rate, successfully detected 13 lignin monomers and 6 lignin dimers from the hardwood chips. These results demonstrate the potential of supercritical fluids and green solvents in the mild and benign extraction of lignin from wood.

Summary: Extreme changes in climate, especially temperature, can affect herbal plants globally. This study investigated the impact of high temperatures and exposure duration on the essential oil yield and trichome characteristics of Lippia javanica leaves. The results showed that increasing temperatures led to higher oil yield, longer trichomes, and larger trichome diameters. The study also identified significant chemical differences between the essential oils of control and treated samples, indicating that L. javanica has coping mechanisms against high temperatures.

Summary: A novel method for universal quantification of lignin dimers based on supercritical fluid chromatography with charged aerosol detection (CAD) was developed and applied to quantify lignin dimers in an oil obtained by reductive catalytic fractionation (RCF) of birch sawdust. The applicability of linear regression and quadratic calibration curves for quantification was evaluated and found to be equally appropriate. The response factors of lignin dimers were compared and showed little variation, enabling the use of a single calibrant for these compounds. The importance of chromatographic peak resolution in CAD was stressed and addressed using a digital peak sharpening technique.

Summary: Membrane protected extraction is an innovative technique for isolating and pre-concentrating analytes from complex samples. It allows for sample clean-up, extraction, and pre-treatment to occur in a single step, with the inclusion of solid sorbents ensuring selective double extraction. This approach eliminates the need for additional clean-up steps and provides advantages in terms of selectivity.
