“…[41,46] The concentrations of PCs obtained in African countries are lower than a study done in Hungary (nd to 2910 μg kg −1 ) by Faludi et al and in China at Weihe River (3.54 × 10 3 to 34.09 × 10 3 μg kg −1 ) by Chen et al, but higher than those reported in China (0.0963-0.448 μg kg −1 ) at Yinma River Basin by Zhou and Sun. [44] In sludge samples, the concentrations obtained in this work (0.86-310 μg kg −1 ) were lower than those reported in Japan (0.003-3600 μg kg −1 ), but higher than those reported in Taiwan (2.72-6.35 μg kg −1 ). [25,47] The difference in concentrations in the various matrices from different countries could be due to the increase in industrialization, which continues to cause pollution which has a direct negative impact on the ecosystem.…”

“…[14,41] The concentration obtained in African countries (nd to 98 μg L −1 ) were higher than countries overseas with concentrations ranging from 0.0065 to 0.0308 μg L −1 in Hungary, Danube River, [42] 0.06 to 14.1 μg L −1 in Northwest China, Weihe River, [43] and 0.053 to 0.339 μg L −1 in China, Yinma River Basin. [44] However, a study done by Faludi et al in Hungary (Lake Balaton) revealed higher concentrations of 20.6-888.0 μg L −1 compared to African countries. [45] In wastewater, the concentrations observed in this study (4.12-83.30 μg L −1 ) were higher compared with other South African provinces like Eastern Cape (nd to 2.20 μg L −1 ) as reported by Farounbi and Ngqwala.…”

Ten phenolic compounds (PC) concentration levels were determined in river water, wastewater, sediments and sludge using solid phase extraction (SPE) microwave assisted extraction (MAE) and ultrasonic extraction (UE), and their ecological risk was evaluated. All the extraction methods showed good sensitivity with limit of detection and limit of quantification values at 0.01–2.00 and 0.02–6.07 µg L−1 for SPE, 0.05–1.20 and 0.17–3.17 µg kg−1 for MAE and 0.09–1.33 and 0.26–3.54 µg kg−1 for UE, correspondingly. Recovery ranges of 75.2–112% (SPE), 80.9–110% (MAE) and 79.3–119% (UE) were obtained. The PC concentrations in wastewater matrix were within the maximum allowable limit except for 2,4‐dichlorophenol at sampling point wdv4. In river water, at Camps Drift the highest concentrations compared to other sampling points was measured, however, all were within the acceptable limits. The risk quotient values exhibited high ecological risk in majority of the sites, with effects range median values indicating toxic effects to the surroundings likely to occur frequently. The probable carcinogenic risk potential was notably found to be high for adults with increment life cancer risk through dermal exposure (ILCRderm) values of 5.34 × 10−2 and 5.92 × 10−2 compared to that for children at 1.26 × 10−2 and 1.39 × 10−2 for both sludge and sediment samples.

Lead (Pb) is a heavy metal that negatively affects human health. Many studies have shown the relationship between lead exposure and various human activities, of which automobile service stations with gasoline emissions are considered the main cause. However, a limited number of studies have specifically considered lead exposure from automobile stations in Vietnam, as well as its impact on human activities and the surrounding natural resources. The objective of this study was to assess the possible risks of lead exposure to the surrounding agricultural and non-agricultural farms of a bus station located in the center of Dalat city, Lamdong province, Vietnam. To address this objective, 45 samples were collected from the soil, irrigated water resources, and vegetable crops of areas both close to and far away from the bus station. These samples were tested using the atomic absorption spectrometry technique. Our findings demonstrated higher lead concentration levels from all three types of samples collected from areas near the bus station. Of which, soil and water samples showed higher than normal exposure values of lead, but these were still under the allowed limits established by the Vietnam standard. Different from the soil and water, vegetable samples surrounding the bus station presented greater lead contamination than the permitted limit. High risk quotient (RQ) indexes were detected to point out that accumulative consumption of leaded vegetables over time could cause lead poisoning and harm human health. This study not only provides significant inferential evidence of the risk of lead exposure to agricultural activities and human health in Vietnam, but also delivers a real-life example for a real-world context.

“…At the same time, they are also a kind of important organic raw materials in the field of agricultural production and are widely used in the manufacture of pesticides, insecticides, and herbicides [ 197 , 198 , 199 ]. Their wide use in industry and agriculture makes them a large number of residues in the environment and a common organic pollutant in water, which have potential carcinogenicity, teratogenicity, and mutagenicity, with wide source, great harm and refractory degradation [ 200 , 201 , 202 ]. Among them, phenol and its derivatives (such as bisphenol A, chlorophenol, nitrophenol, etc.)…”

Water pollution is one of the most important problems in the field of environmental protection in the whole world, and organic pollution is a critical one for wastewater pollution problems. How to solve the problem effectively has triggered a common concern in the area of environmental protection nowadays. Around this problem, scientists have carried out a lot of research; due to the advantages of high efficiency, a lack of secondary pollution, and low cost, photocatalytic technology has attracted more and more attention. In the past, MnO2 was seldom used in the field of water pollution treatment due to its easy agglomeration and low catalytic activity at low temperatures. With the development of carbon materials, it was found that the composite of carbon materials and MnO2 could overcome the above defects, and the composite had good photocatalytic performance, and the research on the photocatalytic performance of MnO2-carbon materials has gradually become a research hotspot in recent years. This review covers recent progress on MnO2-carbon materials for photocatalytic water treatment. We focus on the preparation methods of MnO2 and different kinds of carbon material composites and the application of composite materials in the removal of phenolic compounds, antibiotics, organic dyes, and heavy metal ions in water. Finally, we present our perspective on the challenges and future research directions of MnO2-carbon materials in the field of environmental applications.
