Article Abstract
Background: Uptake of Government-promoted sanitation remains a challenge in India. We aimed to investigate a low-cost, theory-driven, behavioural intervention designed to increase latrine use and safe disposal of child faeces in India.
Methods: We did a cluster-randomised controlled trial between Jan 30, 2018, and Feb 18, 2019, in 66 rural villages in Puri, Odisha, India. Villages were eligible if not adjacent to another included village and not designated by the Government to be open-defecation free. All latrine-owning households in selected villages were eligible. We assigned 33 villages to the intervention via stratified randomisation. The intervention was required to meet a limit of US$20 per household and included a folk performance, transect walk, community meeting, recognition banners, community wall painting, mothers' meetings, household visits, and latrine repairs. Control villages received no intervention. Neither participants nor field assessors were masked to study group assignment. We estimated intervention effects on reported latrine use and safe disposal of child faeces 4 months after completion of the intervention delivery using a difference-in-differences analysis and stratified results by sex. This study is registered at ClinicalTrials.gov, NCT03274245.
Findings: We enrolled 3723 households (1807 [48·5%] in the intervention group and 1916 [51·5%] in the control group). Analysis included 14 181 individuals (6921 [48·8%] in the intervention group and 7260 [51·2%] in the control group). We found an increase of 6·4 percentage points (95% CI 2·0-10·7) in latrine use and an increase of 15·2 percentage points (7·9-22·5) in safe disposal of child faeces. No adverse events were reported.
Interpretation: A low-cost behavioural intervention achieved modest increases in latrine use and marked increases in safe disposal of child faeces in the short term but was unlikely to reduce exposure to faecal pathogens to a level necessary to achieve health gains.

Environmental risks from impacts of industrial solid wastes applied on agricultural land in China: a comprehensive overview.

With the rapid development of industrialization in China, more and more industrial solid wastes (ISWs) are generated in industrial production processes. Under the pressure for safe disposals or utilization of ISWs as resources, and the demand for soil pollution remediation in China, there have been attempts to incorporate ISWs into agricultural land as soil amendments, while the environmental impacts of ISWs applied on agricultural land have aroused great concerns. This paper presents a comprehensive overview regarding the environmental risks from impacts of 7 types of ISWs (including blast furnace slag, steel slag, magnesium slag, coal-fired flue gas desulfurization gypsum, phosphogypsum, calcium carbide slag, and ammonia-soda residue) applied on agricultural land.

Dye pollution from industrial effluents poses a major environmental threat due to the toxicity, mutagenicity, and carcinogenicity of synthetic dyes. Conventional treatment methods-physical, chemical, and biological-often suffer from limited efficiency, high operational costs, and secondary pollution. Carbon-based nanomaterials have emerged as promising alternatives, with carbon nanodots (CNDs) gaining attention for their unique physicochemical properties.

Introduction: Poor solid waste management occurs when household owners fail to properly segregate, store, and dispose of waste at unauthorized dumping sites or in open fields throughout the town. This negligence leads to environmental pollution, water contamination, and adverse health effects in developing urban areas. The 3Rs (reduce, reuse, and recycle) are fundamental principle in solid waste management.

Background: Inadequate water, sanitation, and hygiene (WASH) infrastructure in rural healthcare facilities in India, poses significant challenges to effective infection control, contributing to the prevalence of healthcare-associated infections (HAIs) and poor patient outcomes. Despite ongoing global efforts to enhance WASH standards, these facilities often lack the necessary resources and management systems to sustain improvements. Supportive supervision has emerged as a potential strategy to address these gaps.

With the rapid growth of large-scale livestock farming in China, the safe disposal and resource utilization of anaerobic biogas residue (BR) have become critical challenges. This study systematically investigated the temperature-dependent (400-700 °C) transformation of piggery biogas residue pyrolysis products (biochar, tar/wood vinegar, pyrolysis gases) and their environmental risks. Results show that pyrolysis temperature significantly affects product distribution and properties: At 600 °C, biochar exhibits the maximum specific surface area (38.
