Summary: Air pollution in West and Central Africa, like in other parts of the world, has significant impacts on health and meteorology. This study demonstrates the potential of magnetic methods to monitor air quality at street level in the medium-sized city of Maroua by analyzing magnetic particles in Neem tree bark and leaves. The results show that the magnetic particles primarily originate from particulate emissions due to urban activities such as traffic and wood burning.

Summary: Equations have been developed to predict the partitioning of gas/particle and dust/gas in indoor environments, and these equations have been verified by global monitoring data. The assumption of instantaneous equilibrium for compounds with high partition coefficients may not be valid. The newly developed equations provide a tool for accurate assessment of human exposure to SVOCs in the indoor environment.

Summary: Occupational exposure during waste sorting is associated with various health outcomes. This study compared the impact of work in fully automated waste sorting plants (AWSP) versus manual waste sorting plants (MWSP) on personal exposure to bioaerosols and related health effects. The results showed that workers at AWSP had lower exposure levels to inhalable dust, thoracic dust, and endotoxins compared to MWSP, but higher levels of fungal fragments, fungal spores, and actinobacterial spores. Microbial DNA exposure varied within and between types of waste sorting plants. Exposed workers also reported more common health symptoms compared to the unexposed control group.

Summary: This study aimed to determine the effects of radon on respiratory inflammation, asthma symptoms, and lung function in inner-city asthmatic school children. The results showed that the high radon exposure group had a greater change in fractional exhaled nitric oxide (FENO) between warm and cold seasons, and radon concentration was associated with the frequency of asthma symptoms. Therefore, radon may be a modifiable environmental risk factor for increased asthma morbidity.

Summary: Six phthalates were measured in settled dust on different indoor surfaces in 30 university dormitories. The detection frequencies for most of the phthalates were high, except for one. The study found that phthalate levels were higher in bedside dust than on table surfaces, suggesting a nonuniform distribution in the sleep environment. The simulation showed that the daily intake of one phthalate was the highest among the targeted compounds, and the contributions of daytime and sleeping time exposures to total phthalate exposure were roughly equal.

Summary: This study found that HIV infection is associated with impaired pulmonary gas exchange, independent of emphysema severity. Even in individuals without chronic obstructive pulmonary disease (COPD), HIV infection leads to lower lung diffusing capacity for carbon monoxide (DLCO). The joint influence of HIV and COPD further exacerbates the impairment in DLCO. Further research should investigate other factors, such as pulmonary vascular disease, that may contribute to DLCO impairment in individuals living with HIV.

Summary: Environmental justice refers to the right of all people to live in a healthy environment, be protected against environmental hazards, and participate in decisions that impact their communities. Disproportionate exposure to hazards associated with allergic diseases in communities of color and low-income populations has resulted in health disparities, fueled by systemic racism and discriminatory practices. Achieving environmental justice requires investing in at-risk communities to improve access to safe housing, clean air and water, employment opportunities, education, nutrition, and healthcare, ultimately leading to greater health equity in allergic diseases.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.
