This tragedy brought attention to the dangers of lead exposure from mining, and it brought to light the need to address industrial, occupational and household sources of lead poisoning. According to the World Health Organization (WHO), there is no safe level of lead exposure. Lead exposure can also cause anaemia and damage the kidneys and other organs. Health authorities must also make blood lead testing available to high-risk communities and workers. This is why information on lead exposure should pair with clear guidance on practical steps to reduce exposure.
