“…This fact corroborates Camani and co‐workers, who reported that lower CA values represent a hydrophilic characteristic and favor the interaction of membranes with aqueous systems 92 . If applied to treat water contaminated with PTEs, the hydrophilicity of the membranes containing C20A and the appliance of the EIPS/NIPS method may favor the flow of the contaminant solution and reduce encrustations, improving the treatment and removal of contaminants, in dependence on the chemical nature of the contaminant 99 …”

The method employed for membrane preparation and nanoparticle incorporation in membrane systems can affect their properties. This work aims to compare the better strategy to obtain membranes from the preparation of PBAT [Poly(butylene adipate co‐terephthalate)] containing nanoclay Cloisite® 20A (C20A) (0, 0.5, and 1 wt.%) by combined Evaporation/Non‐solvent Induced Phase Separation (EIPS/NIPS) or dip coating methods. The SEM, TGA, contact angle measurements, FTIR, XRD, mechanical testing, and cost analysis characterized EIPS/NIPS to dip coating membranes. EIPS/NIPS membranes had smaller pores (0.3–0.5 μm), with a more homogeneous pore diameter distribution due to C20A nanoclay insertion. PBAT/0.5% C20AEIPS/NIPS was the more hydrophilic membrane (37°) with better mechanical properties proven by statistical analysis. The cost analysis showed that EIPS/NIPS membranes production cost per square meter (m2) was lower (US$ 73.4–73.8) than dip coating (US$ 89.0–99.2). The EIPS/NIPS method was the most economically and statistically advantageous, and its properties can favor future applications for PTEs removal in aqueous media.

“…Arsenic is an environmental chemical substance of great significance to animal health ( 11 , 134 ). Sodium arsenate, sodium and arsenic pentoxide, and disodium or monosodium acid are all deadly forms of As ( 107 , 135 ), and their environmental contamination poses a serious health risk. Arsenic is a harmful element that is found everywhere and has become more concentrated in water and soil as shown in Figure 3 ( 136 , 137 ).…”

Toxicity with heavy metals has proven to be a significant hazard with several health problems linked to it. Heavy metals bioaccumulate in living organisms, pollute the food chain, and possibly threaten the health of animals. Many industries, fertilizers, traffic, automobile, paint, groundwater, and animal feed are sources of contamination of heavy metals. Few metals, such as aluminum (Al), may be eliminated by the elimination processes, but other metals like lead (Pb), arsenic (As), and cadmium (Ca) accumulate in the body and food chain, leading to chronic toxicity in animals. Even if these metals have no biological purpose, their toxic effects are still present in some form that is damaging to the animal body and its appropriate functioning. Cadmium (Cd) and Pb have negative impacts on a number of physiological and biochemical processes when exposed to sub-lethal doses. The nephrotoxic effects of Pb, As, and Cd are well known, and high amounts of naturally occurring environmental metals as well as occupational populations with high exposures have an adverse relationship between kidney damage and toxic metal exposure. Metal toxicity is determined by the absorbed dosage, the route of exposure, and the duration of exposure, whether acute or chronic. This can lead to numerous disorders and can also result in excessive damage due to oxidative stress generated by free radical production. Heavy metals concentration can be decreased through various procedures including bioremediation, pyrolysis, phytoremediation, rhizofiltration, biochar, and thermal process. This review discusses few heavy metals, their toxicity mechanisms, and their health impacts on cattle with special emphasis on the kidneys.

“…To perform the task of As removal from water, numerous techniques have been applied, including chemical precipitation (Oshima et al, 2022; Vega‐Hernandez et al, 2019), membrane filtration (Algieri et al, 2022), ion exchange techniques (Karakurt et al, 2019), adsorptive flotation (Zhu et al, 2023), and the use of adsorbents (Najib & Christodoulatos, 2019). Among these methods, the adsorption method for As is the most popular technique, effectively concentrating the substance onto an adsorbent material that can be easily removed from the pollution source to aid in the treatment of the solid adsorbent material.…”

This research introduces an enhanced limonite‐based composite fiber adsorbent for arsenic (As) removal. The modification involves creating polyethersulfone (PES)–limonite composite fibers loaded with 60 wt% limonite powders, designed to be applicable in water flow environments. The fibers were prepared using a wet‐spinning process based on phase inversion, with varying concentrations (10, 20, and 30 wt%) of PES in NMP solution. The composite fiber with 10 wt% NMP exhibited a porous structure and demonstrated efficient absorption of both As(III) and As(V). Adsorption followed the Langmuir model, with qm values of 1.5 mg/g for As(III) and 3.2 mg/g for As(V) at pH 6. In column experiments, As removal rates increased with contact time, attributed to decreased flow rates (1 mL/min). Moreover, increasing fiber column height led to enhanced removal rates, as indicated by the Adams–Bohart model. The mechanism for As(V) removal involved the formation of an inner‐sphere complex through ion exchange between α‐FeOOH and HAsO4− and H2AsO42− in an aqueous solution at pH 6.8.Practitioner Points Changing the polyethersulfone ratio in the composite leads to variations in the appearance of limonite within each composite fiber. Limonite composite fibers effectively remove As(III) and As(V) at neutral pH. The adsorption behavior follows Langmuir kinetic model, the qm of 1.5 mg/g for As(III) and 3.2 mg/g for As(V). Longer columns and contact times enhance arsenic (As) removal in practical water treatment systems. Adam–Bohart model aids in predicting breakthrough and saturation time in As adsorption column design.
