The study reviews smallscale gold mining in the Philippines and assesses economically mercury pollution and other development problems of the industry. The end purpose is to suggest measures to address the problems and promote better environmental and overall management of smallscale mining. The study uses secondary data from mining
The MercuryProblem in Artisanal Gold Mining Mercurybased artisanaland smallscale gold mining(ASGM) causes more mercury pollution than any other human activity.[1] In this practice, mercury metal is used to extract gold from ore as astable amalgam. The amalgam is then heatedtoevaporate the mercury and isolate the gold. While mercury amalga

Smallscale gold mining accounts for 37 % of global mercury pollution. Millions of poor people have to resort to this type of mining as the only way of sustaining their families. 2 A large part of the mercury used in the final step of gold extraction ends up as mmsized droplets in dumps (tailings) from which mercury slowly evaporates to the atmosphere.
A major source of air pollution from mercury, artisanal and smallscale gold mining releases approximately 400 metric tons of airborne elemental mercury each year. Located in over 55 countries, small scale gold buying and refining facilities (commonly referred to as Gold Shops) are an important part of this production process, and are a major cause of air pollution from mercury.
Article 7 and Annex C of the Convention address artisanal and smallscale gold mining (ASGM) water mercury Mercury vapors in the air around amalgam burning sites can be Mercury Exposure due to ASGM .

High levels of mercury concentrations were found in the hair and blood samples of the miners and other affected people as well as in fish, soil sediments and forest and river ecosystems in small scale gold mining areas of the Amazon re gion.
Carrying Capacity of Mercury Pollution to Rivers in the Gold Mining Area of Pancurendang Village, Banyumas Wastewater from smallscale gold processing is causing mercury contamination in the river. It is important to know the estimation of the carrying capacity of river pollution due to mercury to support the improvement of the river ecosystem.
