(11 cards)
What metal cations does lead compete with?
Calcium, zinc, iron
Lead competes with these metal cations for absorption and biological functions.
Where can lead be stored in the body?
In bones
Lead can accumulate in bones, affecting long-term health.
What does lead induce that contributes to its toxicity?
Oxygen radicals
Lead depths antioxidant enzymes, leading to oxidative stress.
What are the primary sources of lead exposure?
Inhalation and ingestion
Common routes of lead exposure include contaminated air and food.
How can lead affect a developing baby?
It can cause developmental issues

Who are considered vulnerable populations for lead exposure?
Painters, miners, farmers, children, pregnant women, high traffic flow areas
These groups are at increased risk due to occupational or environmental exposure.
What are some acute signs of lead toxicity?
Abdominal pain, constipation, nausea, vomiting, headache, fatigue, convulsions
These symptoms indicate immediate health risks from lead exposure.
What are some chronic signs of lead toxicity?
Anemia, fatigue, kidney dysfunction, restless legs, hypertension, infertility, sleep issues, myalgia
Chronic exposure leads to long-term health complications.
What role does calcium play in relation to lead?
Calcium stops lead from moving

What is used to treat lead exposure?
Iron
Iron supplementation can help mitigate the effects of lead.
What is a recommended approach for managing chronic lead exposure?
Remove source, use glutathione, zinc, and copper to increase SOD, taurine, coriander
These treatments aim to enhance detoxification and reduce oxidative stress.
