“…Arsenic is toxic in the four oxidation states (+V, +III, 0, -III), and trivalent and pentavalent arsenic are the most common species found in ecosystem (Rahman et al, 2014). This metalloid is persistent in the environment, enters the biota through primary consumers, and biomagnifies (Alvarado-Flores et al, 2019). Mitochondrial oxidative stress via ROS has been linked to arsenicinduced neurotoxicity (Vahidnia et al, 2007).…”

Urban dust is a reservoir of potentially toxic elements (PTEs) that can be incorporated into aquatic ecosystems where they bioaccumulate and biomagnify causing toxic effects. The aim of this work was to assess the PTEs’ concentrations and toxicity to Caenorhabditis elegans of inorganic extracts from urban dust of Barranquilla, the largest Colombian Caribbean city. Trace elements were analyzed by inductively couple plasma-mass spectrometry. PTEs concentration decreased in the order Sr > Cu > Ba > Mo > Se > Cr > V > Ni > As > Zn > Rb > Mn > Sb > Co > Sn > Cd > La > Ce >Tl ≈ Bi > Ag ≈ Pb. Inorganic extracts from urban dust affected physiological parameters in the nematode, such as survival, growth and locomotion. Lethality showed a positive relation with Sr and negative with V. Growth displayed a negative association with Mo. Expression of mtl-2, sod-4, and unc-25 genes was induced by PTEs. The results suggest that C. elegans is a sensitive organism capable of responding to exposure to urban dust extracts, being a suitable sensor for the implementation of warning systems related to risks to biota associated with air pollution.

“…According to the international water quality standards, arsenic levels above 0.010 mg/L exposure result in bioaccumulation, mainly in the muscles, liver and kidney of freshwater organisms, including sh (Cui et al, 2021). One recent report observed very high biomagni cations up to 2.05 ± 0.30 mg Kg − 1 in freshwater sh, although water contained very low arsenic concentration 0.001 to 0.003 ppm (Alvarado-Flores et al, 2019). These ndings indicate that aquatic animal-based food should be regularly monitored for arsenic concentration irrespective of harvesting or culture sources.…”

“…A range of studies revealed that human and animal exposure to different levels of arsenic causing acute, sub-acute and chronic toxicity in animals (Bharti and Srivastava 2009;Bharti et al 2012a; and humans and affects their body physiology and health (Tchounwou et al, 2019;Alvarado-Flores et al, 2019). The latest global number of people infected with arsenicosis, which exceeds the World Health Organization's (WHO's) safe standard for drinking water by 10 ppb, is around 230 million, which has increased dramatically in a decade (Shaji et al, 2021).…”

Arsenic toxicity is an important worldwide health problem of humans and animals due to environmental and occupational exposure through arsenic polluted water, air, soil and food items. It has a multifaceted health impact on animals, human beings, and the environment. Therefore, various experimental and clinical studies were undertaken and had been undergoing to understand its pathogenesis, identify the key biomarkers, medical and economic impact on the affected populations, timely detection and amelioration. However, despite these long-investigated studies, no conclusive information is available for prevention and control of arsenic toxicity, mainly due to complex epidemiology, scattered approach, and repetitive work. Hence, there is a need for literature that exclusively brings information on epidemiology, pathogenesis, and ameliorative measures of arsenic toxicity, which can help researchers and policymakers for effective future planning research and community control programs. In the above view, this article presents an extensive review on the current understanding of arsenic toxicity, detection methodologies, epidemiology, and remedial measures for the bene ts of researchers, academicians, and policy makers in controlling arsenic eco-toxicology and direction for direction futuristic research.

“…Concentrations of total arsenic in whole or muscle tissues of marine organisms worldwide range from below the detection limit of the analytical method, usually 0.01-0.6 μg/g dry weight (depending on the method). Pollution of aquatic ecosystems with toxic elements is a worldwide problem because of the environmental persistence and biomagnifications in food chain (Ali et al, 2019;Flores et al, 2019).…”

The Bojana River is outflow of the Skadar Lake. River is shared by Albania and Montenegro, it forms part of their border before flowing into Adriatic Sea. During most of the year the water quality of the Bojana River is acceptable, but pollution increases the most frequently in summer period.For this study, research of toxic elements (Pb, Cd, Hg, As) in the water and sediment of the Bojana River, as well as in the muscle tissue and digestive tract tissue of thinlip grey mullet (Chelon ramada) was done at the end of the summer season. This research of toxic elements in muscle tissue and digestive tract tissue of thinlip gray mullet is done for the first time for this species, as well as bioconcentration factor (BCF), biota sediment accumulation factor (BSAF) and Spearman correlation between the matrices. The grade of metals concentrations decreased in the subsequent order: As>Pb>Cd=Hg in water and As>Pb>Cd>Hg in sediment. The order of decreasing concentration for metals in muscle tissue is as follows: Hg>Pb=Cd=As and in digestive tract tissue of thinlip grey mullet: Pb>Hg>Cd=As. The highest values of BCF in muscle tissue of fish have been established for Hg and Cd and in digestive tract for Pb and Hg. The values of biota sediment accumulation factor (BSAF) decreased in the following order: Hg>Cd>Pb=As for muscle tissue and Hg>Pb>Cd>As. for digestive tract tissue.
