<![CDATA[This study aims to review the occurrence of microplastics in some commercial aquatic organisms. Microplastics are small plastic particles with a diameter of less than 5 mm. Effluent, stormwater, agricultural, and surface runoff introduce microplastic to freshwater basins. Hydrodynamics and hydrology encompass microplastics. River flow speed can cause turbulence and riverbed instability, increasing microplastic concentrations. Fish, shellfish, and crustaceans ingest microplastics in proportion to their quantity in freshwater and marine environments. Human activities cause variations in the form, color, and size of microplastics in the biota. Animals absorb microplastics through trophic transfer. Increased microplastic residence time before ingestion promotes trophic transmission. Lower food concentration and aggregation enhance microplastic retention in zooplankton guts, increasing transmission to higher-trophic-level species. Most studies show that microplastics in biota are discovered in fish and crustacean intestines and bivalve tissues. Microplastic buildup can disrupt live organisms' growth and reproduction, induce oxidative stress, obstruct the digestive system, and damage the intestine. Microplastics may harm people's health if they eat contaminated seafood that contains them, but more research is needed. ]]>

<![CDATA[According to the World Health Organization, particulate matter (2.5 m) is responsible for more than 4 million deaths worldwide. In real-time, low-cost sensors have assisted in the measurement of PM indoors. SentiAir, a low-cost instrument used in this study, monitors particulate matter (1, 2.5, and 10), as well as nitrogen dioxide, sulphur dioxide, carbon dioxide, ozone, temperature, and relative humidity. The goal of this study was to place the sensor in a typical household indoor space and evaluate all variables for 30 days as an initial investigation assessment. The sensor's proper procedure was strictly observed. PM1 (17.80 μg/m3), PM2.5 (25.21 μg/m3), PM10 (27.61 μg/m3), CO2 (419.7 ppm), O3 (24.75 ppb), NO2 (66.52 ppb), SO2 (48.04 ppb), temperature (34.1 °C), and humidity were the results (mean) (64%). Once those findings were compared to those of the WHO, it was discovered that PM2.5 and PM10 were well within the 24-hour guideline values of 25 and 50 μg/m3, respectively. However, PM2.5 may pose a risk. Temperature and humidity had a significant impact on the PM and gases. Cooking, especially frying and baking, produced a great increment in PM indoors.]]>

<![CDATA[The effects of crude oil pollution on soil physicochemical properties, microflora, and ecotoxicity were evaluated. Soil samples were contaminated with crude oil, and the effects of contamination on the physicochemical parameters, microflora, and growth index of bean (Phaseolus vulgaris) seeds were studied over a 6-month period. The heterotrophic bacteria isolated from the uncontaminated soil were Micrococcus, Klebsiella, Flavobacterium, Bacillus, Pseudomonas, and Serratia species, and the moulds included microbes such as Aspergillus niger, Fusarium, and Mucor sp. Petroleum contamination increased the pH of the soils to alkaline values while increasing the total nitrogen, organic carbon, and phosphorus contents. Electrical conductivity, nitrogen content, and phosphorus content were significantly reduced after petroleum contamination (p ˂ 0.05). The heavy metal contents of the contaminated soils decreased with increasing remediation time. Zinc, total nitrogen, total organic carbon, and electrical conductivity contents were statistically significantly different among samples throughout the bioremediation period (p ˂ 0.05). The ability of isolates to utilise hydrocarbons was highest for Pseudomonas and Bacillus species and lowest for Klebsiella and Serratia species. After a germination period of 12 days, a germination test showed that the bioattenuated polluted soil improved germination of bean seeds. Bioattenuation methods should be used and improved as a means of remediating petroleum-polluted sites because they are cost-effective and environmentally friendly.]]>

<![CDATA[While microplastics have been detected in various spheres of the environment, there are few studies examining their abundance in higher education institutions, where their exposure to students and staff could raise concern. This study aims to quantify and characterise the microplastics in the soil of a higher education institution in China. Surface soil samples were collected in triplicate from nine sampling sites distributed evenly across teaching, recreational, and residential areas on campus. The soil samples were sieved with a 5 mm screen, and the fractions passing through the sieve were digested with 30% hydrogen peroxide. Microplastics were density-separated from the digested soil and observed under the microscope. ATR-FTIR was used to determine their compositions. This study reveals a higher abundance of microplastics in teaching and residential areas (150–700 items/kg and 50–650 items/kg, respectively) as compared to recreational areas (0–450 items/kg), with the highest mean abundance (516.7 items/kg) recorded for residential areas. Fibrous and fragment microplastics (31.5% and 33.3%, respectively) were most common in the soil samples, with the former more prevalent in residential areas. There were more black microplastics (36.4%) and white microplastics (29.1%) than those of other colors. Microplastics 0.5 mm constituted the largest fraction (64.3%) of total microplastics recovered and polyethylene microplastics were most abundant (35.2%). This study contributes to a better understanding of microplastic pollution in the compounds of higher education institutions, which could be positively linked to the human activities within those institutions.]]>

<![CDATA[The rapid increase in population, urbanization, industrialization, and changes in consumption patterns have given rise to many environmental problems, which mainly include air, land, and water pollution. In Khartoum North, Khartoum State, Sudan, there was a lack of a compatible solid waste management system. These resulted in a decline in environmental health, and the majority of the yards were turned into dumps (kusha). The current study focused on the effects of uncontrolled dumping of municipal solid waste on groundwater, as well as assessing the risk of physiochemical concentrations in the water around the dumpsite and comparing the differences between the dry and rainy seasons in water samples at Wadafiea Dumpsite, Khartoum North, Sudan. Water parameters such as TSS, Cl, TDS, Ca, Mg, SAR, and Na exceeded the controlled 1 (1.333) and 2 (1.332) levels of water and was within the Sudanese Maximum Values, the bounds of Canadian Guideline Values, and WHO Values.]]>

<![CDATA[Ikorodu Lighter Terminal is an important lagoon port in Lagos, Nigeria. However, the intense anthropogenic activities that take place around the port could potentially pollute the water. This study assessed the safety of human exposure to the water around the port. Samples of the water were assayed for physicochemical parameters, namely: electrical conductivity, biochemical oxygen demand (BOD), total suspended solids (TSS), total dissolved solids (TDS), pH, turbidity, hardness, calcium, chloride, sulphate, nitrite, and phosphate. Moreover, heavy metals, including lead, manganese, copper, cadmium, nickel, and chromium, were analyzed, and their values were used to estimate potential health risks. Also assayed was the presence of microorganisms. The water samples had non-permissible levels of nitrite, oil and grease, and BOD. The concentrations of the heavy metals as well as their average daily ingestion and average daily dermal exposure were within the tolerable limits, except Ni. However, their hazard quotient and carcinogenic risk via ingestion and dermal contact exceeded the tolerable limits. Safe levels of bacteria, coliforms, and fungi were detected in the water. Based on these results, the water may expose users to health hazards. There is a need for policies geared towards the safety of human exposure to the water.]]>

<![CDATA[Waste generation and disposal, particularly of plastics, have grown significantly over time due to the rapid expansion of urban development. Aquatic species are especially threatened by plastic pollution because the aquatic ecosystem serves as a sink for all contaminants. The capacity for regular development and reproduction is crucial for both human and wildlife health. The endocrine system, which comprises numerous glands that emit hormones to control blood sugar, growth, reproduction, metabolism, and the development of the brain, normally controls these functions. The majority of the synthetic organic chemicals used in plastics come from petroleum. It is well known that their effects cause the endocrine system's regular operation to be disrupted. Plastics are produced at a low cost, and their light weight and adaptability make them candidates for a wide range of uses in all facets of daily life. Plastic waste can enter the ecosystem through waste discharges from oil and gas platforms, aquaculture, and landfills, as well as through litter such as bags and plastic bits used as abrasives. Because they include indigestible particles that fill the stomach and lessen appetite, plastics have been implicated in harming the health of a variety of creatures. They were also discovered in the gastrointestinal tract of individual fish after one week, which disrupted the food's flow to the intestinal mucosa and had an impact on the fish's growth and physical condition. Additionally, fish exposed to plastics have been shown to exhibit changed behavior, decreased sperm motility, and increased thyroid hormone production. Therefore, exposure to varied amounts of polyethylene impairs an organism's normal physiological functioning and has the potential to impact negatively on both the health of the organism and its offspring. This review was aimed at highlighting the risks of plastic exposure to fish and people through the food chain.]]>

<![CDATA[A study was conducted at the Wadafiea landfill in Al Khartoum Bahri (North), Sudan, to determine the level of microbial contamination in water samples collected from nearby areas around the landfill. The purpose of this study was to evaluate the impact of solid waste disposal in open dumps and assess the associated risks to water. The study tested for coliform bacteria (E.coli) and compared the seasonal differences between the samples collected during the dry and rainy seasons. The results indicated higher levels of E.coli contamination in each season, with the rainy season samples showing particularly high levels (66.03 × 10⁴ cfu/ml) compared to the dry season (31.93 × 10⁴ cfu/ml). It was concluded that the groundwater was highly polluted due to the current landfill location. The local authorities and the department of solid waste management were advised to close this landfill and relocate it to the outskirts of Al Khartoum Bahri (North) city. Additionally, it was recommended that international regulations for standard landfills should be maintained and implemented.]]>

<![CDATA[This study aimed to determine the efficiency of media pollutant removal from municipal wastewater with high concentrations of ammonia and phosphorus in constructed wetlands (CWs). The study utilized secondary data from previous studies that were published in credible sources. The removal efficiencies of the five media used in the constructed wetland, namely, peat-cattails, cattails, peat, Viteveria zizanioides, and Phragmite karka, were compared. The results showed that CWs with Viteveria zizaniode exhibited the best performance on average, removing 84% nitrogen and 86% phosphorus. Peat was also effective in attenuating pH. Humic and fulvic acids in peat moss can be released quickly in an aqueous environment under alkaline conditions, effectively lowering the pH value. The combination of Viteveria zizaniode and peat significantly improved pollutant removal efficiency in municipal wastewater with high concentrations of ammonia and phosphorus.]]>

<![CDATA[As a result of urbanization and industrialization, emerging pollutants have become a global concern due to contamination and their potential adverse effects on the ecosystem and human health. However, the characteristics and environmental fate of emerging pollutants remain unclear due to the limitations of current technologies. Emerging pollutants are predominantly released into the environment through anthropogenic activities and accumulate in water, soil, air, and dust. Despite their typically low concentrations in the environment, exposure to these pollutants can result in endocrine disruption and other health impacts on the human body, as well as oxidative stress in organisms. Phytoremediation is a green biotechnology that utilizes plants in association with microorganisms to mitigate pollutants in contaminated areas through various mechanisms. It represents a cost-effective and environmentally friendly approach, although its efficacy can be hindered by both the biological condition of plants and ecological factors. Moreover, phytoremediation generally requires a longer remediation timeframe compared to alternative technologies. The remediation of emerging pollutants aligns with the "green liver model" theory, which encompasses translocation, internal transformation and conjugation, and sequestration as classification categories. Presently, several challenges are being encountered in this field, including a lack of information regarding emerging pollutants and their metabolism in plants, the absence of a modeling framework and standardized monitoring practices, limitations in sampling and analysis technologies, as well as phytoremediation technologies. Therefore, further research is warranted to delve into the behavior of emerging pollutants and their interactions with plants, aiming to develop or enhance existing technologies. Additionally, the concept of phytomanagement should be considered, as it offers a sustainable approach to environmental remediation.]]>
