Abstract: There is an increase preference for plant-based repellents due to their effectiveness, friendliness to the environment and biodegradable nature. It is therefore necessary to ascertain the safety of these repellents by analysing their heavy metal content. This study indicates that the heavy metals, lead and arsenic content of Azadirachta indica seed oil cream and Citrus sinensis peel oil cream as mosquito repellents are significantly low therefore, they are very safe for use according to the Ghana Standard Authority specification. These results provide new insight into the safety of these mosquito repellents.
