ABSTRACT This study aimed to determine aflatoxin M1 (AFM1) in dairy sheep, goats, and camel milk in Hail, Saudi Arabia, and evaluate methods for reducing AFM1. A total of 67 milk samples were collected from Ghazala and Al-Shweimis villages, Hail. AFM1 in milk samples was analyzed using enzyme-linked immunosorbent assay (ELISA) and high-performance liquid chromatography (HPLC) with fluorescence detection. Results revealed concentration of AFM1 in goat and camel milk samples from Ghazala was higher than that in goat and camel milk samples from Al-Shweimis with a significant difference (p<0.05) using both ELISA and HPLC methods. The mean AFM1 concentration using ELISA for goat milk was (12.96 ± 2.23 ng/l), while the AFM1 concentration for camel milk was (1.54 ± 0.29 ng/l). Microwave heating and boiling are effective methods to reduce the AFM1 in milk. The highest AFM1 removal percent was 42.96% by microwave and 12.32 % by boiling milk samples.

This study aimed to investigate the effects of fresh water and seawater flooding on phosphorous (P) and nitrogen (N) dynamics in two calcareous soils (Biscayne and Krome) of South Florida using a 28-day greenhouse flooding experiment. Porewater samples were collected at three depths over four periods (1, 7, 14, and 28 days) of flooding and analyzed for selected water quality parameters. Results showed that seawater-flooded Biscayne soil had a 4.4 fold higher porewater soluble reactive phosphorus (SRP) concentration than freshwater. Additionally, porewater SRP concentration and total phosphorus (TP) in Biscayne soil increased with prolonged flooding duration and column depth. Furthermore, both freshwater and seawater flooding increased porewater NH4+ - N concentration; however, the increase was more pronounced in seawater flooded samples. NH4+ - N concentration also increased with flooding duration. Overall, the study highlights the risks of nutrient leaching from seawater flooded coastal soils that could contribute to the deterioration of surface and groundwater quality.

Discrimination of the catalytic ability of heterogeneous biochar components is often challenging. Herein, a sewage sludge-derived biochar (SDBC) was prepared to activate peroxydisulfate (PDS) for tetracycline (TC) degradation. To verify the contribution of different carbon components, SDBC was bleached with NaClO2 and CH3COOH to remove noncondensed aromatic carbon (NAC) contained in biochar, which was confirmed by 13C Nuclear Magnetic Resonance. The batch degradation experiment revealed that NAC removal decreased TC degradation by SDBC from 84.1% to 33.2% within 2 h, indicating its significant role in PDS activation. The quenching and electron paramagnetic resonance experiments suggested a very minor contribution of radical pathway in TC degradation. Instead, the electron transfer pathway predominated TC degradation mechanism as inferred by electrochemical tests. This is likely ascribed to formation of a biochar-PDS metastable complex, facilitating electron transfer from tetracycline-like compounds. An X-ray photoelectron spectroscopy confirmed that the percent of graphitic N in SDBC decreased after the degradation reaction, which suggested graphitic N is an important active site in biochar. Besides, acid-washed SDBC did not change TC degradation behavior excluding significant contribution of minerals in SDBC to PDS activation. Thus, the roles of biochar components in catalyzing PDS were quantified for the first time, proving insight for selection and manipulation of biochar in catalyzing PDS in environmental application.

Meadow soils are one of the important agricultural soil types, biochar is a good soil amendment, whereas the studies on the effects of biochar additions on carbon and nitrogen contents, as well as bacterial communities of meadow soils, were seldom carried out. The effects of one nitrogen addition rates (no addition, 0.2% addition) and two biochar addition patterns (no addition, 1% addition, 3% addition) on the carbon and nitrogen contents, as well as bacterial communities of meadow soils, were investigated by conducting a one-year indoor incubation experiment. Biochar addition increased the relative abundance of Proteobacteria, Chloroflexi and Bacteroidota. The combination of biochar and nitrogen source significantly increased the total organic carbon, ammonium nitrogen, nitrate nitrogen and total nitrogen content of the meadow soil. Therefore, the addition of moderate amounts of biochar to meadow soils can contribute to sustainable ecological agriculture as a form of soil improvement.

In this work, column experiments were applied to investigate the transport of four kinds of microplastics (MPs) under a series of ionic strength (IS) conditions. Under 0.1 mM IS, PMMA MPs showed the highest mobility, as well as the PET MPs showed the lowest mobility. With the IS increased, the transport of all kinds of MPs in porous media was generally reduced to the minimum. The transport reducing efficiency of PMMA MPs and PET MPs was lower than that of the PVC MPs and PP MPs. It was found that both the hydro-chemical conditions and basic properties showed combined effect on MPs transport in porous media. The DLVO results were well used to describe the deposition of MPs onto sand surface and excavate the transport behaviors of MPs. The one-site kinetic deposition model was successfully conducted to fit the observed breakthrough curves. Findings from this study elucidated the key factors controlling the MPs transport in porous media, contributing to the prediction and assessment of the environmental risks of MPs.
在本工作中，采用柱实验研究了四种微塑料(MPs)在一系列离子强度(IS)条件下的传输。在0.1 mM IS下，PMMA MPs的迁移率最高，PET MPs的迁移率最低。随着IS的增大，各种MPs在多孔介质中的输运通常减小到最小。PMMA MPs和PET MPs的输运降低效率低于PVC MPs和PP MPs。发现水化学条件和基本性质对MPs在多孔介质中的输运有共同影响。DLVO结果很好地描述了MPs在沙面上的沉积，并揭示了MPs的输运行为。单点动力学沉积模型成功地拟合了观测到的突破曲线。本研究结果阐明了多磺酸盐在多孔介质中运移的关键控制因素，有助于多磺酸盐环境风险的预测和评估。

The properties of metal(loid)s in the environment are mainly determined by their chemical forms. The chemical forms of metal(loid)s affect their possible chemical and biochemical reactions, toxicity, mobility, and bioavailability in the environment. Sequential chemical extraction (SCE) has been successfully used to clarify the chemical forms of soil metal(loid)s. However, quite a few SCE procedures have been applied for speciation analysis of plant samples; there is no systematic discussion in such a field. The current review deals with the SCE of plant metal(loid)s, and compares the extraction procedures and the extractants in different SCE methods. It has been found that some chemical forms are unreliable for plant SCE analyses. The forms can be the phosphates or oxalates of some specific metals in plants, such as gadolinium or chromium, which cannot be fully extracted by the designated extractants, 2% acetic acid, or 0.6 M/L HCl. Therefore, SCE methods for the non-bivalent metal(loid)s have been emphasized in this work. Moreover, the application status, development trends, limitations, and future directions for SCE methods of plant metal(loid)s have been discussed.
