“…These changes were attributed to interactions of cellular components with the metal ion, which could be described as follows. (1) The carbonyl groups (C=O) of amides likely present in the cell membrane decreased considerably [54]. (2) The band located at 1543 cm −1 , which corresponds to the carboxylates (COO-), exhibited a decrease in intensity, possibly due to the biosorption of the metal ion [54].…”

“…Metal ions reach ecosystems through various natural processes and anthropogenic activities [1]. The leading causes of their natural release from the lithosphere and subsequent accumulation in ecosystems include erosion, volcanic activity, and forest fires, from which these metals undergo accumulation cycles without causing adverse effects on the environment [2].…”

“…On the other hand, several human activities extensively use metals such as lead, cadmium, molybdenum, vanadium, and chromium to manufacture multiple products, including batteries [3], plastic [4], projectile lubricants, insecticides, ceramics, paint and glass pigments [5], photography [6], welding, wood conservation agents, and tanning agents, and in the chemical industry as a whole [7]. The frequent use of metals in industrial settings is closely linked to environmental pollution due to inadequate residue management that accelerates metal accumulation in sediments and water-receiving bodies [1].…”

In this study, 338 microorganisms, comprising 271 bacteria and 67 fungi, were isolated from sediment samples collected from underexplored Pacific and Caribbean regions of Colombia. Screening trials were conducted on selected strains (n = 276) to assess their tolerance to cadmium (Cd2+), lead (Pb2+), and zinc (Zn2+), leading to the identification of six bacteria capable of withstanding 750 mg·L−1 of each heavy metal ion. Three promising microorganisms, identified as Enterobacter sp. INV PRT213, Pseudomonas sp. INV PRT215, and Stenotrophomonas sp. INV PRT216 were selected for lead removal experiments using LB broth medium supplemented with 400 mg·L−1 Pb2+. Among these, Pseudomonas sp. INV PRT215 exhibited significant potential, removing 49% of initial Pb2+ after 240 min of exposure (16.7 g wet biomass·L−1, pH 5, 30 °C). Infrared spectra of Pb-exposed biomass showed changes in functional groups, including carbonyl groups of amides, carboxylate, phosphate, hydroxyl, and amine groups, compared to the not-exposed control. These changes suggested interactions between the metal and functional groups in the biomass. The findings of this study highlight the potential of microorganisms derived from coastal marine environments as promising candidates for future applications in bioremediation of polluted environments contaminated with heavy metals.

“…Metal pollution, such as lead (Pb) and arsenic (As), poses a significant threat to ecosystems due to its toxic, non-biodegradable, and persistent nature. Heavy metals easily accumulate in soil, water, and sediment, leading to substantial environmental hazards (Prasad Ahirvar et al, 2023). Mohamed et al developed a cost-effective, sustainable adsorbent for the efficient removal of Pb(II) from water.…”

“…The presence of metal pollution, such as arsenic (As), has a harmful impact on the ecosystem because of its toxic, non-biodegradable, and persistent characteristics. Arsenic rapidly accumulates in the soil, water, and sediment, posing a threat to the environment (Prasad Ahirvar et al, 2023). The presence of As in the water is a result of weathering processes that occur in rocks and sulfidic minerals.…”

The presence of arsenic in water bodies poses a significant risk to both human health and the environment. Arsenic (As) contamination in water sources is a global environmental concern caused by both natural processes and human activities. Due to its toxic and persistent nature, arsenic has detrimental effects on ecosystems and human wellbeing. This study aimed to elucidate the mechanisms behind arsenic accumulation in water bodies. In aquatic environments, arsenic concentrations in drinking water have been reported as high as 1,320 μg/L (Nicaragua), while groundwater levels exceeded 5,000 μg/L (Thailand), and wastewater contained up to 134,000 μg/L (landfill leachate in Brazil). Furthermore, bioaccumulation of arsenic (μg/g) in fish species ranges from 0.4 (catfish in the Paraná River Delta, Brazil) to 362 (Pteromylaeus bovinus, Northern Adriatic Sea). Recent research has predominantly focused on removing arsenic from aqueous solutions through adsorption methods. Notably, nanoparticle adsorbents and graphene-based adsorbents demonstrate a high capacity for arsenic removal from water bodies.
