A number of factors, including biological, psychological and environmental ones, as well as behavioral, social, cultural, health-related, and sociocultural aspects, could contribute to the prevalence of high blood lead in local children. On a genetic level, there are certain traits that can cause some people to be more susceptible than others to lead poisoning. An example is having lower levels of iron and zinc. Pre-existing conditions like anemia may also be a factor.
Mentally, individuals may not seek medical care when necessary due to a lack or knowledge of symptoms and potential dangers. In the environment, old infrastructures and housing that has peeling paint or is in a state of disrepair can emit lead into the air. This is particularly dangerous when it occurs in an urban area where there are many people living close to each other.
There are several other sociocultural issues at work, including poverty that limits the availability of healthy foods and substandard housing due to financial constraints. Finally, this issue is further complicated by the fact that there are not enough health resources available and insurance gaps.
