A study has revealed that residual chemicals cause rampant lung ailments in residents in parts of Joburg...According to the Benchmarks Foundation, more than half (56.1%) of residents identified in communities such as Riverlea had respiratory ailments (cough, sinus, asthma and TB) as their most persistent ailment. Four percent of respondents also reported eye problems. The foundation also revealed that after over a century of mining, Johannesburg’s residents are living on the largest concentration of radioactive uranium on the planet...Its recently released report, titled Waiting To Inhale, the 12th in its policy gap series, examined the household health and wellbeing of four communities affected by mining in Soweto. It found many residents of Riverlea, for example, were living on oxygen machines.
