BackgroundGallbladder cancer (GBC) is a rare but lethal malignancy with a dismal prognosis. The aim of this study is to analyze the burdens and trends of GBC across the world based on geography, socioeconomic development (based on human development index [HDI]), and gender.MethodsGLOBOCAN 2020 database was used to extract data (2020−2040) relating to the incidence and mortality of GBC across the world.ResultsAsia had the highest burden of GBC with India and China contributing to majority of the absolute burden. The burden of GBC by age standardized rate was highest in Latin America (Bolivia and Chile) and Southeast Asia (Bangladesh and Nepal). Medium HDI countries had a higher mortality rate compared to very high HDI countries. Females had a higher predilection for GBC across different regions and socioeconomic groups. GBC burden is expected to significantly increase across the world by 2040 with variable trends across different regions, age groups, and genders.ConclusionThe global burden of GBC will significantly increase over the next two decades with marked regional and demographic variations. The results of this study will empower national and global health leaders to develop policies to address the increasing burden of this lethal malignancy.

“…Namely, As is classified as a Class 1 carcinogen element by the International Agency for Research on Cancer [ 4 , 5 ]. According to WHO, 300 million people are affected by As contamination of groundwater [ 6 ], while, only in Bangladesh, nearly 43,000 deaths are attributed to chronic As exposure every year [ 7 ]. The main causes of As contamination are different natural or anthropogenic processes and sources ( Figure 1 ).…”

“…As(III) has been reported to be more toxic to humans than organic As and As(V) [ 13 ]. The main sources of As exposure for humans are the use of contaminated water for drinking/cooking, growing of crops in contaminated soils and/or irrigation with contaminated water and consumption of contaminated sea food [ 2 , 7 , 14 ]. Once As has entered the human body, it can cause a wide range of acute and chronic toxic effects and diseases, with or without specific symptoms, depending on As exposure, dosage and chemical form.…”

Biotechnology Advances in Bioremediation of Arsenic: A Review

Arsenic is a highly toxic metalloid widespread in the Earth's crust, and its contamination due to different anthropogenic activities (application of agrochemicals, mining, waste management) represents an emerging environmental issue. Therefore, different sustainable and effective remediation methods and approaches are needed to prevent and protect humans and other organisms from detrimental arsenic exposure. Among numerous arsenic remediation methods, those supported by using microbes as sorbents (microbial remediation), and/or plants as green factories (phytoremediation) are considered as cost-effective and environmentally-friendly bioremediation. In addition, recent advances in genetic modifications and biotechnology have been used to develop (i) more efficient transgenic microbes and plants that can (hyper)accumulate or detoxify arsenic, and (ii) novel organo-mineral materials for more efficient arsenic remediation. In this review, the most recent insights from arsenic bio-/phytoremediation are presented, and the most relevant physiological and molecular mechanisms involved in arsenic biological routes, which can be useful starting points in the creation of more arsenic-tolerant microbes and plants, as well as their symbiotic associations are discussed.

“…The element arsenic is pervasive in the environment and can be poisonous as well as carcinogenic. Widespread arsenic contamination is currently regarded as a serious environmental issue (Rahaman et al 2022). Chronic ingestion of inorganic arsenic, particularly via water consumption, is associated with skin and bladder cancers as arsenic accumulates and concentrates in the liver, lungs, kidneys, and skin tissue (Fatoki et al 2019).…”

The optimal conditions for the green synthesis of nano zero-valent iron ( G-NZVI) using mango peel extract were investigated using a Box-Behnken Design approach. Three factors were considered, including the ratio of iron solution to mango peel extract ratio (1:1-1:3), feeding rate of mango peel extract (1-5 mL/min), and agitation speed (300-350 rpm). The results showed that the optimal conditions for the synthesis of G-NZVI for arsenate removal were a 1: 1 ratio of iron solution to mango peel extract, a mango peel extract feeding rate of 5 mL/ min, and an agitation speed of 300 rpm. Under these conditions, nearly 100% arsenate removal was achieved. X-ray diffractometry ( XRD) , Fourier transform infrared spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Brunauer-Emmett-Teller (BET), and Scanning Electron Microscopy (SEM)with Energy Dispersive X-Ray Analysis ( EDX) methods were used to characterize the properties of the G-NZVI. Finally, the arsenate removal efficiency of the G-NZVI was compared against commercial nano zero-valent iron (C-NZVI). The results revealed that the G-NZVI was roughly five times more efficient at arsenate removal than the C-NZVI. The influence of background species such as chloride (Cl -), phosphate (PO4 3-), calcium (Ca 2+ ), and sulfate (SO4 2-) was studied to evaluate their effects on arsenite removal. As a result, Cland Ca 2+ were shown to play a role in promoting arsenite removal, whereas SO4 2and PO4 3were observed to play an inhibiting role.
