Chemistry Classwork
Gold (Au)
-
-
Does the extraction of this element have an impact on health, the environment or the population/society?
ENVIRONMENT= water used in the mining process is polluted with chemicals and then put back into rivers and streams --> taken space from animal habitats
SOCIETY= poor countries people are forced to extract gold --> underpaid --> death (bad conditions and too much work)
HEALTH=
- increased frequency of cancer
- increased frequency of pulmonary tuberculosis
- increased the frequency of insect-borne diseases
