Mining activities cause serious pollution problems that affect health and the
environment. This paper focuses on the environmental and biological effects that mining activity
had on the population living and working in the Riotinto-Nerva area in the last third of the
nineteenth century and the early twentieth century, when this area accounted for approximately
10% of world copper production. To do so, we explore the social, technological, and scientific
responses to environmental pollution caused by mining extraction in this area during
industrialisation. Second, we analyse welfare indicators, such as the heights of conscripts and
mortality rates, so as to examine the social effects of the mining activity. Third, municipal health
and education expenditures are examined to study the intervention made by the local authorities to
address the welfare problems caused by the mining work and environment. Finally, we examine
whether the health policy had positive effects on the health of the population after the negative
external effects of copper mining in this area had been mitigated. The findings show that the
negative impacts of copper exploitation on the environment and welfare could only be diminished
using health policies to combat this kind of urban penalty.
