Objective: Determine the Perceived Impact on the Artisanal Miner's Health from Quinchía's Municipality (Colombia) by the Use of Cyanide and Mercury in the Amalgamation Process of Gold.
Methods: Quantitative, descriptive research in a sample of 28 active miners exposed to cyanide and mercury. The process of gold amalgamation was characterized, a survey of symptom perception was carried out and laboratory tests were carried out to detect the concentration of mercury and cyanide in blood.
Results: 50% of the miners are in the trade between 21 and 30 years, with an exposure of 2.6 hours/day to mercury and cyanide. 33% of miners have levels of mercury concentration in blood between 4-4.9 micrograms per liter (μg/L), as well as refer to symptoms in the nervous and digestive systems. The results of cyanide in blood are negative.
Conclusions: Blood mercury concentrations are associated with time in the trade, hours of exposure to mercury and perception of symptoms. The results of cyanide in blood are not coincident with the symptoms reported by the miners. Although the toxicity of these chemical substances is recognized, traditional and prohibited methods are still used without taking into account safety protocols and the use of appropriate protection elements. Miners are constantly exposed to procedures that involve health risks, refer undiagnosed symptoms and that could affect the organism in the long term. Prevention and promotion measures are not adopted.

This study assesses cyanide and cyanidation wastes management practices among small, medium and large-scale gold leaching plants in Siaya County, Kenya. The socio-economic benefits of gold extraction through cyanidation of mercury-contaminated tailings notwithstanding, the study establishes inadequate cyanide and cyanidation wastes management practices which could potentially cause significant environmental and human health impacts. Through structured key-informant interviews with operators from 15 selected gold leaching plants of varying scales of operation, along with field observations, and quantitative analysis utilizing both bivariate and inferential statistical tools, the study reveals inadequacies in cyanide, cyanidation wastewater, and tailings management practices.

The Ministry of Environment of Korea has proposed a ban on landfill disposal of municipal solid waste (MSW) from 2026. Thus, it is inferred that the amount of incineration ash will increase drastically. Against this backdrop, this study assessed the applicability of a plasma melting process to fly ash.

Clean water is essential for drinking, household use, and agriculture. Researchers studied 39 sites near Tamla nala and Nunia nala channels in Durgapur and Asansol City (West Bengal) to assess the deterioration level of water due to industrial discharge. During the first phase out of three, the researchers conducted a spatial representation of various physicochemical parameters, such as temperature, pH, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Total Hardness (TH), Electrical Conductivity (EC), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), significant anions such as chloride (Cl), nitrate (NO), phosphate (PO), sulfate (SO), cyanide (CN) and fluoride (F), as well as heavy metals/metalloids such as lead (Pb), cadmium (Cd), chromium (Cr), iron (Fe), copper (Cu), nickel (Ni), mercury (Hg) and arsenic (As).
