Comparison of two carbonaceous supported Fe-rich adsorbents for arsenate removal: A functionalisation and mechanistic study with applicability to groundwater treatment
In this study, two iron-rich carbonous adsorbents were compared for the removal of arsenate (As(V)) from groundwater. Biochars (FeO-biochar and FeO-pyrochar) derived from biomass waste were functionalised in two different ways with iron chloride for comparation. Batch and dynamic parameters were optimised to achieve >99% As(V) removal efficiency. Experimental data best described by the pseudo-second order kinetic model, while multi-stage diffusion appeared to limit mass transfer of As(V). Among the isotherm models evaluated, the Freundlich model best described the experimental results with high correlation coefficients ...

Interactions between methyl octabromo ether flame retardant and expandable polystyrene microplastics in the photoaging process
In this study, we simulated the photoaging process of flame retardant-added EPS (FR-EPS) and common original EPS (OR-EPS) microplastic (MP) particles with and without methyl octabromoether flame retardant (MOBE) in the laboratory to explore the effect of MOBE on the photodegradation of EPS. Results showed that MOBE accelerated size reduction and surface hole formation on the particles, hastening the shedding and replacement of particle surfaces. FR-EPS particles exhibited a weight loss exceeding that of OR-EPS, reaching 40.85 ± 3.72% after 36 days of irradiation. Moreover, rapid physical peeling of the FR-EPS surface was ...

Exposure to UV-B filter octylmethoxycinnamate and human health effects: focus on endocrine disruptor actions
This article aims to provide an overview of the UV filters' photoprotection, emphasizing the OMC and the possible negative effects it may have on the public health. Moreover, the current legislation will be addressed. In summary, the recommendations should be rethought to assess their risk-benefit, since the existing literature warns us to endocrine-disrupting effects of OMC. Further studies should be focus on the toxicity of OMC alone, in mixture and should consider its degradation products, to improve the knowledge of its risk assessment as EDC.PMID:38704047 | DOI:10.1016/j.chemosphere.2024.142218 (Source: Chemosphere)

Application of machine learning for antibiotic resistance in water and wastewater: A systematic review
Chemosphere. 2024 May 2:142223. doi: 10.1016/j.chemosphere.2024.142223. Online ahead of print.ABSTRACTAntibiotic resistance (AR) is considered one of the greatest global threats in the current century, which can only be overcome if all interconnected areas of humans, animals and the environment are taken into account as part of the One Health concept proposed by the World Health Organization (WHO). Water and wastewater are among the most important environmental media of AR sources, where the phenomena are generally non-linear. Therefore, the aim of this study was to investigate the application of machine learning-based met...

Chemosphere. 2024 May 2:142217. doi: 10.1016/j.chemosphere.2024.142217. Online ahead of print.ABSTRACTLong-term exposure to environmental chemicals can detrimentally impact human health, and understanding the relationship between age distribution and levels of external and internal exposure is crucial. Nonetheless, existing methods for assessing population-wide exposure across age groups are limited. To bridge this research gap, we introduced a modeling approach designed to assess both chronic external and internal exposure to chemicals at the population level. The external and internal exposure assessments were quantified...

Glyphosate-environmental variables interaction: how does it affect the parasite Chordodes nobilii?
This study is the first to report the combined effects of glyphosate, temperature, pH and time on a freshwater animal. It demonstrates that a specific combination of factors determines the effect of glyphosate on a non-target organism. The potential use of C. nobilli as a bioindicator is discussed. In the context of global warming and considering that the behavioral manipulation of terrestrial hosts by gordiids can shape community structure and the energy flow through food webs, our results raise concerns about possible negative effects of climate change on host-parasite dynamics.PMID:38704040 | DOI:10.1016/j.chemosphere.2...

Optimizing removal of antiretroviral drugs from tertiary wastewater using chlorination and AI-based prediction with response surface methodology
Sci Total Environ. 2024 May 2:172931. doi: 10.1016/j.scitotenv.2024.172931. Online ahead of print.ABSTRACTChemical and pharmaceutical chemicals found in water sources create substantial risks to human health and the environment. The presence of pharmaceutical contaminants in water can cause antibiotic resistance development, toxicity to aquatic organisms, and endocrine disruption. Hence, the elimination of chemicals and other contaminants from wastewater prior to its release is a burgeoning concern in the domains of engineering and science. The use of treatment technologies in wastewater treatment plants can remove pharmac...

Association of cigarette smoking with changes in macroeconomic conditions
This study uses data from the 1987-2022 Behavioral Risk Factor Surveillance System and state-level employment rates from the US Bureau of Labor Statistics to estimate the association between macroeconomic conditions and cigarette smoking. Our finding suggests a positive association, which constantly declined with time after the 2001 recession. We find that a one percentage point increase in the employment rate is associated with a 1.4% higher likelihood of smoking cigarettes in the overall sample but declined to 0.4% among cohorts surveyed from 2011 to 2022. We also find strong positive and heterogeneous associations among...
