Ineffective waste site closures in Brazil: A systematic review on continuing health conditions and occupational hazards of waste collectors.

There are approximately 15 million people engaged in waste collection or recycling activities in the world. Some of these dump sites are informal and people work in environments that are labor-intensive, unregulated, unregistered, low-paid, unrecorded, and environmentally hazardous. A systematic review was conducted to assess consequential health conditions and occupational risks that affect waste collectors in Brazil.
