Prevalence of arsenic in drinking water is threatening millions of people’s health over the world. It leads to many skin disorders, kidney troubles, heart diseases, diabetes, paralysis, etc., and most interestingly it is in focus as a cancer-causing agent in recent times [1–4]. People especially from the developing countries are mostly affected by its contamination as they are unable to avail efficient cost-effective tools and techniques to get relief from this deadly contaminant [5]. Besides certain acute health hazards, prolonged intake of arsenic-contamination in water causes many serious health effects, called arsenicosis [6, 7]. Cost-effective, simple methods using easily, and widely available materials therefore, can bring some sigh of relief to those people [8]. Adsorption is one of such widely used concept when arsenic is present in trace level [9].

Arsenic contamination via food, water, soil, and dust, and inhalation of atmospheric arsenic causes the development of different acute and chronic toxicity resulting in various illnesses (Monachese et al., 2012; Coryell et al., 2019). The acute toxicity includes bloody urine, GI discomfort, diarrhea, headaches, vomiting, convulsions, coma, and death; whereas the chronic toxicity causes skin lesions, diabetes, blisters, blackfoot disease, organ failure/damage, metabolic dysregulation, diabetes mellitus, cardiovascular disease, pregnancy complications, and neurological symptoms (Lu et al., 2014; Richardson et al., 2018; Coryell et al., 2019). The International Agency for Research on Cancer (IARC) has listed arsenic as group I carcinogens which causes various cancers such as lung, skin, bladder, etc. (Richardson et al., 2018; Coryell et al., 2019). Interestingly, perturbation of gut microbiome is believed to be associated with arsenic-mediated human illnesses (Monachese et al., 2012).
Groundwater Arsenic Catastrophe
Published in M. Manzurul Hassan, Arsenic in Groundwater, 2018
Groundwater arsenic contamination has been detected in some parts of Australia. In an investigation of the relationship between environmental exposure to arsenic from contaminated soil and drinking water and the incidence of cancer in the Victoria region, particularly around gold mining areas, arsenic concentrations in groundwater were found to be in the range of <1 to 300,000 μg/L, and in surface water were <1 to 28,300 μg/L (Hinwood et al., 1999). Arsenic concentrations of up to 7000 μg/L were measured in shallow groundwater in the Gwelup area in Perth, and in 1976 no arsenic was detected in any of the investigated shallow wells, whereas in 2004 after extensive dewatering and peat excavation, concentrations were in excess of 1000 μg/L (Appleyard et al., 2006). Smith et al. (2003) reported natural arsenic in Holocene coastal barrier sands in the Stuarts Point Coastal Sands Aquifer of New South Wales (maximum 70 μg/L) and the underlying Yarrahapinni Fractured Rock Aquifer (maximum 337 μg/L). Arsenic varied from 7.4 to 396 mg/kg in soils of Ballarat-Creswick area of Central Victoria, and the average in soil (39.0 mg/kg) was markedly higher than the Environmental Protection Agency recommended maximum for soils and the Australian and New Zealand Environment Conservation Council's environmental level of 20 mg/kg (ANZECC, 1992). The mean level (39 mg/kg) in soils is well above the normal global range (6.0 mg/kg), and extreme levels (>190.0 mg/kg) in soils were found in areas of mine tailings sites in Australia (Sultan, 2007). In addition to anthropogenic sources such as mining activities and pesticide use, different minerals present a significant source of natural arsenic contamination to the environment.

Arsenic contamination is a global, agricultural, environmental, and health issue due to its non-degradable, extraordinarily toxin, and cancerous effect (Chen and Costa 2021; Phyu et al. 2020). Arsenic contamination occurs through anthropogenic activities and geological sources. Growing populations, urbanization, and industrialization are commonly recognized as anthropogenic sources of trace metal poisoning in emerging countries (Nawab et al. 2018; Rehman et al. 2018). Due to insufficient treatment of industrial emissions and waste management, as well as overuse of already scarce water resources, water contaminants such as trace metals, viruses, bacteria, nitrates, and salt enter the waterways (Sarfraz et al. 2018). Naturally, arsenic can be released into the environment through coal ore, iron oxide, erosion, and weathering of rocks (Shokoohi et al. 2021; Joardar et al. 2021). Further, streams originating from crust layers released into water sources during natural weathering are among the major sources of geogenic arsenic contaminants (Shokoohi et al. 2021; Joardar et al. 2021).

In the majority of cases, arsenic exposure is said to deactivate the human enzyme system by binding through various biological ligands. Over the years, epidemiological studies have shown that chronic exposure to arsenic may cause various types of cancers like skin, lung, kidney, liver and bladder. Worldwide, arsenic-based agricultural products such as herbicides, fungicides and insecticides were extensively used in the past (Fennema, Karel, Sanderson, Walstra, & Whitetaker, 2002).For the first time in the 1950s the effects of arsenic exposure to human health appeared which included vascular, respiratory and skin lesions in both children and adults after the intake of contaminated water. Subsequently, there has been considerable efforts to develop methods to contain arsenic contamination using treatments to remove the heavy metal from water before use and regulating its emissions.

Arsenic contamination in soils and groundwater is of global concern. While most efforts focus on anthropogenic sources, groundwater contamination by As from geological sources was reported by Wang et al. (2021). They demonstrated the hydrogeological patterns of As, which often co-exists with anions F and I. Particularly, they proposed four basic genetic types of geologically-contaminated groundwater, and provided a theoretical framework to understand the complex genetic mechanisms and predicting their spatial and temporal distribution (Wang et al., 2021). Bundschuh et al. (2021) summarized information regarding As pollution in 20 Latin American countries. They focused on the developments during the past 10 years and provided a country-specific overview of the occurrence and impacts of As exposure in different environmental matrixes including soil, water and sediment.
