Lead Interference with Red Blood Cell Development

Introduction:
Lead is a toxic heavy metal that can cause serious health problems in humans. One of the most significant effects of lead exposure is its interference with the development of red blood cells.

Red Blood Cells:
Red blood cells, also known as erythrocytes, are responsible for carrying oxygen throughout the body. They are produced in the bone marrow and require a variety of nutrients, including iron, vitamin B12, and folic acid, to develop properly.

How Lead Affects Red Blood Cell Development:
Lead interferes with the production of heme, a vital component of hemoglobin, which is the protein that carries oxygen in red blood cells. Lead can also damage the cell membrane of red blood cells, causing them to become more fragile and prone to breaking down.

Consequences of Lead Exposure:
Children are particularly vulnerable to the effects of lead exposure, as it can impair their cognitive development and lead to learning difficulties. In adults, lead exposure can cause anemia, high blood pressure, and kidney damage.

Conclusion:
The emissions from vehicles are a significant source of lead pollution. To minimize the risk of lead exposure, it is essential to reduce emissions from vehicles and take steps to protect against exposure, such as avoiding areas with high levels of lead pollution and using personal protective equipment when working in potentially contaminated areas.

Yes option b is correct becoz lead interference with binding capacity of hemoglobin with oxygen and thus it effect RBC.
