“…Cases of chronic arsenic poisoning continue to rise in India despite multiple programs by governmental and non-government organizations to mitigate the adverse health effects of arsenic. 37 Newer arsenic remediation technologies have been either approved or under consideration through these programs. Arsenic toxicity can be prevented by raising awareness of this condition.…”

Context. Arsenicosis is caused by long term (6 months plus) ingestion of arsenic above a safe dose, characterized by skin lesions and possible involvement of internal organs. Arsenicosis is common in India and Bangladesh where naturally occurring high concentrations of arsenic in the earth's crust contaminate ground water, causing adverse health effects. Case Presentation. We report a case of a 55-year-old Indian male, resident of a known arsenic endemic region of Uttar Pradesh who suffered from characteristic pulmonary and cutaneous features of chronic arsenic toxicity which included radiological findings of interstitial lung disease, hyperkeratotic lesions over the palms and soles, rain drop like pigmentation over the trunk, and carcinomatous changes at the wrist joint. The patient was started on chelating agents (d-penicillamine) and oral retinoids (isotretinoin) followed by the surgical excision of the carcinoma. Discussion. Environmental contamination with arsenic is a well-known health hazard in South Asian countries. The main source is consumption of contaminated ground water for domestic purposes. Cutaneous lesions, internal organ involvement including interstitial lung disease and carcinomas as observed in our patient have been reported in the literature. Various mechanisms like epigenetic changes and arsenic-induced immune suppression have been proposed for the development of cutaneous carcinomas with prolonged exposure to arsenic. Relevance to Clinical Practice. Among the various causes of palmo-plantar hyperkeratosis, arsenicosis should be kept in mind when presenting in combination with pigmentary changes and carcinomatous growth from an arsenic-endemic region. Conclusions. People residing in arsenic-endemic regions should be made aware of arsenic-related health hazards. Rainwater harvesting and good nutrition are the simplest measures which could be adopted by the exposed population in affected areas. Several methods have also been employed by governmental and non-government organizations to separate arsenic from contaminated water to combat arsenic-related diseases and carcinomas.

“…• Heavy metal contamination from tanneries by leaching toxifies both soil and ground water. To avoid the entry of heavy metals into the food chain, it is important to remove them from soil and water for which microorganisms such as Pseudomonas aeruginosa and Aspergillus niger are being currently used and could be further engineered to make them more efficient and cost effective in the cleaning process [42][43][44]. • Rubber waste is 12% of total solid waste and can neither be degraded easily nor recycled due to its physical property.…”

“…Rising population and rapid urbanization have left India with water bodies contaminated with toxins such as arsenic, chlorine, fluorine, other heavy metals, and organic effluents and to meet the increasing demand for water, treatment of sewage water is necessary. Industrial set-up utilizing biotechnological solutions could not only provide ecofriendly solutions but also revenue generation [42].…”

Advancement in the field of biotechnology has opened a vast global market. The Indian biotechnology arena is promising for advance and pioneering growth with its immense growth potential which could play a significant role toward India's contribution to global industrial biotechnology. Today, India is one of the fastest-growing trillion-dollar economies in the world and the fifth largest overall, with a GDP (gross domestic product) of $2.94 trillion. Biotechnology (BT) and information technology (IT) are the key drivers contributing to this growth which constitutes approximately 5% of the country's total annual GDP. Indian biotechnology growth is fueled by bio-pharmaceutical, bio-industrial, bio-services, bio-agricultural, and bioinformatics, and among them, the bio-industrial area is one of the most promising and advanced. New approaches which Indian industrial biotechnology is exploring, include harnessing microorganisms for the production of value-added bioactive ingredients such as industrial enzymes, organic acids, bulk chemicals, and single-cell proteins, which have played a predominant role in the overall development of biotechnology after bio-pharmaceuticals. The above factors made India one of the world's top 12 destinations for biotechnology. In this article, we review the status of the biotechnological industry and its future perspective in context to the Indian market and its role in global economy.

“…Human development and rapid population growth have negatively affected water quality, which makes it unsuitable for drinking, and for other daily applications [1,2]. Among the wide range of pollutants available in water, arsenic is one of the most unwanted pollutant that causes water quality to decrease [3][4][5]. The clean potable water is the necessity of human life on earth.…”

Study of PAN Fiber and Iron ore Adsorbents for Arsenic Removal

et al. 2020

The main idea to conduct this study is the treatment of hazardous arsenite (As+3) and arsenate (As+5)from water by two efficient adsorbetns i.e. polyacrylonitrile fiber (organic) and iron ore (inorganic). Polyacrylonitrile (PAN) fibers were chemically modified prior to loading iron using a solution of diethylenetriamine and aluminum chloride hexahydrate. The characterization of PAN fibers was performed through FTIR spectroscopy, which shows the binding of functional groups on PAN fibers surfaces. Atomic absorption spectrometer (AAS) was used to analyze arsenic concentration in samples. The impact of pH, dosage, shaking (contact) time and shaking speed was studied and parameters were optimized for further study. The highest adsorption of 98% is exhibited by modified PAN fiber for As+5 while for As+3 removal is 80%. Modified PAN also showed higher adsorption capacity of 42×103μg/g for As+5 which is better than the As+3 adsorption capacity 33×103 μg/g. Overall results demonstrated that MPAN adsorbent is better than the iron ore adsorbent for the treatment of both As+3 and As+5. Comparative studies of PAN Fiber and iron ore adsorbents revealed that PAN fibers had better adsorption properties than iron ore for As+3 and As+5 in terms of percentage removal and capacity.
