1 What are some examples of environmental sources of exposure of populations to toxic heavy metals? What factors can exacerbate the effects of toxic exposures on populations with low socioeconomic status? 50 words

Some examples of environmental sources of exposure of populations to toxic heavy metals include arsenic, mercury, and lead, which are three of the most deadly toxic heavy metals that impact human populations. These toxins have been known to be significantly dangerous to human populations and are considered human carcinogens. The factors that exacerbate the effects of toxic exposures on populations with low Socioeconomic Status are the fact that these areas are more prone to have plants that release toxins built near their communities, which increases the probability that contamination will leak into their ground water. In addition, these populations are more likely to live in older buildings where lead is still present despite being banned from buildings for many decades in newer model buildings.
