Results reported that the environmental impacts are pervasive worldwide: marine litter, air, soil and water contamination, and the direct interaction of waste pickers with hazardous waste are the most important issues. The activity of the informal sector in developing cities was also reviewed, focusing on the main health risks due to waste scavenging. This paper reviews the main impacts due to waste mismanagement in developing countries, focusing on environmental contamination and social issues.
Open dumping and open burning are the main implemented waste treatment and final disposal systems, mainly visible in low-income countries. Environmental contamination due to solid waste mismanagement is a global issue.
