Throughout the last few years, microelectronic components significantly changed the lives of everyone thanks to the progress brought in the digital and new technology industries with the increasing power of computers, mobile phones etc. Although the components seems invisible, they are present in large number in all electronic devices.

Microelectronics evolves more and progress is increasingly dramatic.

However the microelectronic industry involves a multitude of risks related to microelectronic components which are without consequences for human health.

Although these risks can be removed, increased microelectronic components raises serious problems of recycling and pollution in the emerging countries.

The aim of this article is actually to get us to realize that even though the microelectronic is a revolution, it generates a lot of risks for people but especially pollution for environment.
