Artisanal and Smallscale Miners. Globally 1020 million people including 4 to 5 million women and children work directly in the ASGM sector. 1 These miners are typically the poorest and most marginalized in society and consequently often work outside the formal economy.

ABSTRACT Artisanal and smallscale gold mining (ASGM) is a crucial economic activity in Burkina Faso however it is associated with significant mercury exposure and health concerns. The aim of the present study was to assess the level of mercury (Hg) vapour exposures and occupational behaviours at a representative site using Hg vapour monitor
Smallscale gold mining is usually devoted to secondary deposits as the gold concentrated by gravity processes is free and easy to extract. But also small scale mining practices in primary deposits can be found in the countries under study. For this technography the following phases and aspects were identified and querried Prospection.

The data reported in this paper highlights that artisanal and smallscale goldmining activities can not only produce mercurial contamination that can also release other heavy metals (such as Mn) that may pose a risk to human health. Artisanal and smallscale goldmining activities performed in mountain areas of the Southern Ecuadorian Amazon have incorporated several heavy metals into the
