Gold‑mining and social involvement Gold-mining in Colombia is an activity that involves a diverse group of social agents. Unlike in other extraction activities, there is a high demand for the participation and inclusion of different agents in order to regulate and manage this activity. Gold-mining is performed on different scales,

· In 2009 a mining engineer named Marcello Veiga set out to study mercury air pollution in a part of northwest Colombia called Antioquia Department. This mountainous, conflict-ridden state, where leftist guerillas routinely battle Colombian security forces, is an important center for artisanal and small-scale gold mining (ASGM).
Mining has a long history in Colombia, and especially artisanal and small-scale mining (ASM) has been a livelihood opportunity for many Colombians since colonial times. Today, approximately 72% of mining is ASM and it is often the only livelihood option in rural communities due to the lack of alternative economic opportunities. Therefore ASM is ...

· In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.
