Study Notes
Industrial Toxins: Heavy Metals
- Heavy metals are metallic chemical elements that are toxic and poisonous at low concentrations, and examples include Mercury, Cadmium, Arsenic, Chromium, Thallium, and Lead.
- Heavy metals are natural components of the Earth's crust, and they cannot be degraded or destroyed.
- Heavy metals can enter our bodies via food, drinking water, and air, and some heavy metals are essential to maintain the metabolism of the human body, but at higher concentrations, they can lead to poisoning.
- Heavy metals tend to bioaccumulate, meaning an increase in the concentration of a chemical in a biological organism over time.
- Heavy metals can enter a water supply by industrial and consumer waste, or even from acidic rain breaking down soils and releasing heavy metals into streams, lakes, rivers, and groundwater.
- Lead poisoning is one of the oldest occupational and environmental diseases in the world, and environmental lead exposure has declined considerably due to diminished use of lead in gasoline and other applications.
- Sources of lead exposure include soil and dust, paint chips, contaminated water, parents lead-related occupation, folk remedies, and household plumbing.
- Lead serves no useful purpose in the human body and can be absorbed via the respiratory and gastrointestinal tracts.
- Lead poisoning can result in multi-systemic toxic effects by inhibiting enzyme activity, interfering with the action of essential cations, and altering the structure of cell membranes and receptors.
- The general signs and symptoms of lead toxicity include fatigue, irritability, lethargy, paresthesia, myalgias, abdominal pain, tremor, headache, vomiting, weight loss, constipation, loss of libido, motor neuropathy, encephalopathy, cerebral edema, seizures, coma, severe abdominal cramping, epiphyseal lead lines in children (growth arrest), and renal failure.
- Childhood lead poisoning is now defined as a blood lead level of 10 μg/dl, and the average lead level of American children is 2 μg/dl.
- Mental retardation, aggression, hyperactivity, antisocial behaviors, learning disability, and impairment in memory, auditory processing, and visual-motor integration are some of the adverse developmental outcomes of lead poisoning.
