Toxicity Elemental tin metal, its salts, and its oxides present low toxicity.Tin-plated steel cans are still widely used for food preservation. Exposure levels of 100 mg/m 3 are considered immediately dangerous. Legal permissible exposure from contact or inhalation is typically set around 2 mg/m 3 per 8-hour work day. In contrast, organotin compounds are highly toxic, on par with that of cyanide.

Opencast mining Opencast tin mining accounts for about 7.6% of total tin ore production in the peninsula. Opencast mining involves removal of tin ore rich alluvium by mechani-cal means rather than by water. The excavation of the alluvium is carried out by shovel, dragline or hydraulic excavators. The alluvium is transported to the palong.

Tin mining in Myanmar tends to be a seasonal activity, since water required for processing is in short supply by the end of the dry season (early April), and in excess during the summer rainy seasonflooding underground workings, and making alluvial excavation impossible (Gardiner, 2021, Kettle et al., 2021a). Hence, tin production and
