Millennium development goal in its list of targets have improved health and environment sustainability among other things. Environmental protection guarantees environmental sustainability and directly as well indirectly improves societal health. In the quest to protect the environment, removal of heavy metals which are either carcinogenic or mutagenic has taken the lead.

The use of different adsorbents in the removal of chromium from the environment has been reviewed in this article and areas that need further attention that will improve and enhance its removal were reported. It is hoped that the concerns reported this article will be useful in solving environmental problems caused as a result of chromium contamination
