“…The exact long‐term impact of such gases on rural public health is yet to be ascertained (Akinde & Obire, 2008; Mestrot et al., 2013; Tang et al., 2020; Teo & Teoh, 2011). Nevertheless, most of the toxic arsenic gets removed in this process within a period of 2–5 months, but the effectiveness of the seals enclosing the soak pits and the leaching potential of arsenic for a longer detention time (e.g., in terms of years or decades) is yet to be determined (Hashmi et al., 2018). Furthermore, it is a common practice in rural areas to use dry cow dung for cooking purposes (Sfez et al., 2017).…”

Arsenic is a toxic carcinogen mostly found in subsurface environments. It is released into groundwater mostly via natural geological and hydrological processes. Consumption of such contaminated water leads to serious health crises for mankind. Developing countries in South Asia, particularly the rural regions, have been severely affected by this environmental phenomenon. In India, government authorities have implemented several remedial measures to provide safe drinking water to the rural habitations, ranging from utilization of surface water bodies (e.g., rivers, ponds, etc.) for piped water supply schemes and establishment of groundwater treatment units. This article attempts to review the scientific literature describing the critical situation in India's fourth most populous state of West Bengal and the engineering advances made in the mitigation. The issue of safe disposal or stabilization of arsenic wastewaters generated from the treatment units is often not emphasized in policy discussions. In a concluding note, this article proposes innovations necessary for achieving effective arsenic mitigation in the region that involve both groundwater remediation and waste management in tandem for sustainability.

“…To examine the implications of • OH, naphthalene (NAP) was selected as the model contaminant due to its wide distribution in paddy fields. 1 By systematically scrutinizing the effects of long-term inputs of agricultural amendments, our results are conducive to exploring the effective strategies for enhancing agricultural production and also promoting contaminant attenuation via deepening the mechanism of • OH formation during soil redox fluctuations.…”

“…Paddy soil is the largest type of anthropogenic wetlands used for growing semiaquatic rice, which serves as the staple food feeding about one-half of the world's population. 1 However, the deterioration of paddy soils, such as acidification, infertility, decreasing biodiversity, and organic/inorganic contamination, etc., significantly limits the yield and quality of rice, especially in the southern region of China. 2 Therefore, various agricultural amendments, including chemical fertilizer (e.g., urea), organic manure, and biochar, etc., are widely applied to improve soil quality and mitigate the pollution of heavy metals (e.g., Cd).…”

Hydroxyl radicals ( • OH) play a significant role in contaminant transformation and element cycling during redox fluctuations in paddy soil. However, these important processes might be affected by widely used agricultural amendments, such as urea, pig manure, and biochar, which have rarely been explored, especially regarding their impact on soil aggregates and associated biogeochemical processes. Herein, based on five years of fertilization experiments in the field, we found that agricultural amendments, especially coapplication of fertilizers and biochar, significantly increased soil organic carbon contents and the abundances of iron (Fe)-reducing bacteria. They also substantially altered the fraction of soil aggregates, which consequently enhanced the electron-donating capacity and the formation of active Fe(II) species (i.e., 0.5 M HCl-Fe(II)) in soil aggregates (0−2 mm), especially in small aggregates (0−3 μm). The highest contents of active Fe(II) species in small aggregates were mainly responsible for the highest • OH production (increased by 1.7−2.4-fold) and naphthalene attenuation in paddy soil with coapplication of fertilizers and biochar. Overall, this study offers new insights into the effects of agricultural amendments on regulating • OH formation in paddy soil and proposes feasible strategies for soil remediation in agricultural fields, especially in soils with frequent occurrences of redox fluctuations.
