Lead is one of the oldest toxins existing in the environment because of its nature and extensive use from the ancient times. Lead is commonly known as a silent killer because, at any concentration, without any noticeable symptom it can affect almost all organs in the body.Unsafe blood lead levels may cause lower IQ level, autism, abnormal delivery and may increase the involvement in crime. Generally, pregnant women, fetus and children are the most vulnerable groups to lead poisoning because of rapid bone mobilization and neurodevelopment. Therefore, the aim of this study was to evaluate the awareness about lead among Bangladeshi women of child bearing age. To evaluate the knowledge on exposure to lead, a questionnaire survey was conducted and completed by all participants (Less-educated women, n=62; Educated women, n=52). Data were analyzed by using SPSS (Version20). Appropriate statistical tools were utilized to draw the results. The study findings showed that there is a highly significant difference in economic condition (p<0.0001), home location (p<0.0001), cosmetics use (p<0.0001), even in food habit (p<0.0001) between the groups. Moreover, significant difference has also been found in awareness about lead toxicity among educated and lesseducated women (p<0.0001). However, interestingly, no significant difference was found in the knowledge about the (hidden) sources of lead in everyday life between the groups (p<0.109), frequency of lipstick use (p<0.201) and in the use of coloring agents in food (p<0.724). Since lead exposure reduces the IQ level at any concentration, therefore, scientists have found an economic impact of lead on the society. The importance of this study lies in the fact that, if the women are aware about the sources of lead and consequences of lead toxicity, the body lead burden could be reduced in the next generation as lead can directly affect the fetus from mothers’ exposure.
