The presence of organic compounds in drinking water is well recognized in many developing countries; however, the occurrence of organic contaminants in the groundwater of Saudi Arabia, which is the main source of drinking water in the country, is not well documented. A national comprehensive study was carried out to assess the occurrence of organic compounds in groundwater wells used for drinking water purpose, in different regions of Saudi Arabia. A total of 993 well water samples were collected from all 13 administrative regions of the kingdom. Samples were analyzed for a total of 131 organic compounds using the standard methods. The results indicated that total organic carbon values were in the range of 0.01 to 84.13 mg/L with an average weighted value of 12.61 mg/L. Organic compounds were detected in only 9 regions, with 19.84% of the samples containing organic compounds. Only 96 wells (9.67%) showed contents of organic compounds above the safe limits. Pesticides were not detected in any of the well water samples. Overall, organic compounds were found in only 197 out of 993 wells (19.84%) in the whole country. Most of the wells containing organic compounds were located in residential, industrial, and agriculture areas. Riyadh region and Eastern Province were found to have the most affected wells as compared to other regions. Several regions did not show any organic compounds in the well waters. It can be said that the problem of groundwater contamination with organic compounds in Saudi Arabia is not acute and is manageable at present. It is, however, recommended that a regular monitoring of drinking water wells of all regions should be carried out by the competent authorities for organic compounds to know any contamination if and when it happens. Preventing such contaminants from reaching drinking water sources and protecting drinking water well heads from such contaminants remains a priority.

The Suzuki-Miyaura cross-coupling reaction is an effective process for C-C bond formation in organic synthesis. Herein, we report a NiO nanodot-decorated Pd/SiC catalyst, synthesized by atomic layer deposition, which shows high photocatalytic activity for the Suzuki-Miyaura coupling of both aryl bromides and chlorides with phenylboronic acid at 30 degrees C in air. The Mott-Schottky contact in SiC/Pd enhances the rapid transfer of the photogenerated electrons from SiC to Pd nanoparticles. Moreover, the energy different between the highest occupied molecular orbital of the ultrafine NiO nanodots and the Fermi level of Pd forces a spontaneous electron transfer from NiO to Pd. As a result, the concentrated electrons in the Pd nanoparticles can facilitate the cleavage of C-Br or C-Cl bonds, which normally requires rather high temperatures in thermal processes. The holes left on the SiC support can assist the cleavage of the C-B bond. (C) 2020 Elsevier Inc. All rights reserved.

A series of allyl (1-3) and cinnamyl (4-6) palladium(II) complexes supported by hydroxyl functionalized triazolylidenes have been prepared. All new compounds were fully characterized by means of H-1 and C-13 NMR spectroscopy, FT-IR and elemental analyses. The new triazolylidene palladium complexes were tested as precatalysts in the coupling of aryl chlorides with boronic acids and the coupling of esters with amines to produce biphenyls and amides, respectively. According to the overall results, complexes 4 and 5 displayed the highest catalytic activity in both coupling processes, providing good to excellent yields under mild reaction conditions and using a wide range of substrates.

Ylide-functionalized phosphine (YPhos) ligands allow the palladium-catalyzed alpha-arylation of alkyl ketones with aryl chlorides with record setting activity. Using a cyclohexyl-substituted YPhos ligand, a wide range of challenging ketone substrates was efficiently and selectively monoarylated under mild conditions. A newly designed YPhos ligand bearing tert-butyl groups on the coordinating phosphorus atom is already active at room temperature. The synthetic potential was demonstrated by gram-scale reactions and the succinct synthesis of epsilon-caprolactone derivatives.

Most microplastics (MPs) have undergone extensive aging in the environment. Aged MPs exhibit different physical and chemical properties from unaged ones. Here, we studied the effects of accelerated aging on the characteristics and pyrolysis of commercial pigmented MPs, as well as pigments leaching and their interactions in simulated gastric and intestinal fluids of mammals. We report that the carbonyl index, surface area, and color change of MPs increased after aging treatment. Cracks and fragmentation of MPs facilitated the accessibility of light and oxygen to internal layer and therefore accelerated the aging process. TGA/GC-MS analysis showed that the high temperature resistance of MN decreased after aging. Thermal decomposition of pigments and polyethylene occurred in temperature ranges of 340-406 degrees C and 406-550 degrees C, respectively. Mono (di)-alkenes and saturated alkanes were the thermal decomposition products of polyethylene. Aging of MPs also caused an increased release of pigments and prolonged aging time led to more release in simulated fluids. Pigments would result in fluorescence quenching of the enzymes through binding interactions once they were released from MPs into simulated fluids. Charge neutralization and polymer bridging accounted for the formation of pigment-enzyme complexes and flocs. These novel findings will allow us to better assess how aging process affects the characteristics, leaching, and toxicity of MPs. (C) 2020 Published by Elsevier B.V.

The resolution of samples containing unknown compounds of different nature, or without standards available, as is the case of chromatographic fingerprints, is still a challenge. Possibly, the most problematic aspect that prevents systematic method development is finding models that describe without bias the retention behaviour of the compounds in the samples. In this work, the use of global models (able to describe the whole sample) is proposed as an alternative to the use of individual models for each solute. Global models contain parameters that are specific for each solute, while other parameters -related to the column and solvent- are common for all solutes. A special regression procedure is presented for the construction of global models, which are applied to predict highly complex chromatograms, such as chromatographic fingerprints, for diverse experimental conditions in isocratic and gradient elution. Another interesting application is the prediction of molecular properties, such as log P-o/w from the specific solute parameters of the global models. The examined adapted models are based on the equations proposed by Snyder, Schoenmakers, Neue and Kuss, Jandera, and Bosch Roses to describe the retention. In all cases, the predictive capability was very satisfactory. Two cases of study were considered: chromatograms of camomile extracts analysed using acetonitrile gradients, and a set of 145 known compounds in a wide range of structures and functionalities, eluted isocratically with acetonitrile/water mobile phases.

The adsorption behaviors of Cu(II) and tetracycline (TC) on polyethylene microplastics that were exposed to air (A-PE-MPs), water (W-PE-MPs) and soil (S-PE-MPs) environments for a long time were investigated with batch experiments in this study. FT-IR and GC-MS analysis confirmed that phthalates (PAEs) were released from PE microplastics after exposure to UV light. When exposed to water and soil environments, PE microplastics were colonized by microorganisms and biofilms were formed on their surface. Compared with virgin microplastics (V-PE-MPs), the environment-exposed microplastics possessed higher adsorption and stabilization capacity for Cu (II) and TC. The adsorption isotherm data of V-PE-MPs and A-PE-MPs were well fitted by Freundlich model, whilst the adsorption by W-PE-MPs and S-PE-MPs were better described by Langmuir model. The Boyd equation used in kinetic experiments revealed that V-PE-MPs and A-PE-MPs were additionally affected by intra-particle diffusion compared with W-PE-MPs and S-PE-MPs. The glycosyl composition analysis suggested that the higher adsorption capacities of S-PE-MPs than W-PE-MPs could relate to the different components of extracellular polysaccharides in biofilms. Moreover, density functional theory further verified that Cu(II) and PAE adsorption on microplastics could be enhanced by the generation of Cu-PAE and Cu-PAE-TC complexes. In addition dissolved organic matter exerted opposite effects on the adsorption onto A-PE-MPs and S-PE-MPs due to their different affinity for Cu(II), TC and DOM. This study demonstrated that the contribution of microplastics to heavy metal and antibiotic migration could be affected by the way they exposed to environments.
