This study assesses the environmental damage caused by copper mining on surface water bodies in Chile. The few official records on the discharges and concentrations of arsenic and copper only allow for identifying the impacts of some mining operations in the regions of Coquimbo, Valparaíso, and O’Higgins. The economic valuation is carried out through the impact pathway approach, which relates copper production, discharges, concentrations, and dose-response coefficients to establish effects on health and agriculture. The results show that the economic damage due to water pollution occurs mainly in the regions of Coquimbo and O’Higgins. The above is explained because the greatest externalities are generated in agricultural areas, while the damage to health is low because of the small population exposed (97.6% versus 2.4%). Finally, total damages represent 0.43%, 0.26%, and 0.0001% of copper sales in the mining operations analyzed in the regions of Coquimbo, O’Higgins, and Valparaíso, respectively.

The Bronze Age in Britain is now a term often used to include both the first use of copper c. 2400 bc and also tin-bronze from c. 2100 bc, all of which required the extensive use of copper. Prehistoric mining for this metal has been identified in surface and underground workings in Parys Mine, Mynydd Parys, Anglesey, although almost all of the surface workings are now obscured by the extensive deep spoil from more recent mining in the industrial period. These copper-bearing ores are in bedded lodes, together with some intruded vein deposits. The Bronze Age workings have been exposed underground where they have been intersected by the early 19th century industrial workings on and above the 16 fathom and 20 fathom levels in the Parys Mine. Spoil exposures contain stone hammers (‘mauls’), wood fragments, and charcoal; samples of the latter have been radiocarbon dated with chronological modelling suggesting activity took place in the first half of the 2nd millennium cal bc. Although relatively limited in extent, these important prehistoric mining sites are among the earliest found in the UK. They have survived due to their protection from surface erosion and limited accessibility.

The Great Orme Bronze Age copper mine in Wales is one of Europe's largest, although its size has been attributed to a small-scale, seasonal labour force working for nearly a millennium. Here, the authors report the results of interdisciplinary research that provides evidence that Great Orme was the focus of Britain's first mining boom, c. 1600–1400 BC, probably involving a full-time mining community and the wide distribution of metalwork from Brittany to Sweden. This new interpretation suggests greater integration than previously suspected of Great Orme metal into the European Bronze Age trade/exchange networks, as well as more complex local and regional socio-economic interactions.

In this reconnaissance study, skeletal materials from people, dating from ∼1500 B.P., who lived by or worked at the ancient copper mines and furnaces of the Wadi Faynan in southern Jordan, were analysed using atomic absorption spectrophotometry (AAS) to determine the intensities of accumulation of copper and lead in their bones. Many of the bones analysed contained concentrations of these metals which are comparable to those of modern individuals who are heavily exposed to metals through contemporary industrial processes.

Patterns of partitioning throughout the skeleton of a number of individuals were also studied. These AAS data suggest that within the human organism there may be some ability to influence the patterns of accumulation of copper within the skeleton. The humerus was frequently found to contain more copper than other bones studied. Within the humerus itself, the medial epicondyle frequently contained the highest concentrations, which may indicate a significant degree of organization or control of the process. These metal concentration data together with their toxicological consequences suggest that the health of the ancient human populations must have been adversely affected by exposure during life to copper in the environment. They also point to the need for further detailed studies of metal partitioning within the bones of the human skeleton.

Major investigations were undertaken of the Ecton Copper Mines, Staffordshire, following the discovery of hammerstones and a red deer antler tool dating to the Early Bronze Age during surface and underground exploration in the 1990s. Ecton Hill was surveyed, the distribution of hammerstone tools examined, and two identified sites of potential prehistoric mining close to the summit of the hill excavated in 2008 & 2009. Excavations at Stone Quarry Mine revealed no in situ prehistoric mining activity, but hammerstones and Early Bronze Age bone mining tools from upcast suggest that an historic mine shaft had intersected Bronze Age workings at around 10–25 m depth. On The Lumb one trench revealed evidence for medieval lead mining, while another examined the lowest of four primitive mines associated with cave-like mine entrances along the base of a small cliff. Evidence for prehistoric mining was recorded within a shallow opencut formed by during extraction of malachite from a layer of mineralised dolomite. Traces of the imprint of at least 18 bone and stone tools could be seen and seven different types of working were identified. Most prehistoric mining debris appears to have been cleared out during the course of later, medieval–post-medieval prospection; some bone and stone tools were recovered from this spoil. The tip of a worn and worked (cut) antler tine point was the only such mining tool found in situ at this site but nine tools were radiocarbon dated to c. 1880–1640 cal bc. Bayesian modelling of the dates from both sites probably indicates mining over a much briefer period (perhaps 20–50 years) at 1800–1700 cal bc, with mining at Stone Quarry possibly beginning earlier and lasting longer than on The Lumb. A single date from The Lumb suggests possible renewed mining activity (or prospection?) during the Middle Bronze Age. The dating of this mining activity is consistent with the idea that mining and prospection moved eastwards from Ireland to Wales, then to central England, at the beginning of the 2nd millennium bc. At Ecton the extraction of secondary ores may have produced only a very small tonnage of copper metal. The mine workers may have been Early Bronze Age farmers who occupied this part of the Peak District seasonally in a transhumant or sustained way
