Blood lead level

Lead is a toxic metal that is harmful to human health; there is NO safe level for lead exposure. The degree of exposure depends on the concentration of lead, route of exposure (air, water, and food), current medical condition, and age. It has been estimated that up to 20 % of the total lead exposure in children can be attributed to a waterborne route, i.e., consuming contaminated water. In addition, infants, fetuses, and young children are particularly vulnerable to lead poisoning. This is…

attributable DALYs in high-mortality countries (WHO 2002).” In this scientific paper, I will discuss the neurological effects of lead contamination in public water through a series of case studies in the hopes of urging the Senate Environment and Public Works Committee to place stricter regulation on the EPA in monitoring lead pollution of public and private water. Lead-contaminated water is a significant issue as it is related to neurological and psychological impairments such as learning…

Lead consumption in drinking water Many people who have consumed lead may have to face some serious problems with lead. Consuming water that contains lead, is not only unhealthy but could be fatal. Drinking water that lead is in, can affect many body systems and even do some serious damage. There are many ways that lead can affect people. Lead is known as something that is very dangerous if consumed. A little bit of lead can affect the human's body and the way in functions. If any lead gets in…

“From personal tragedy to public health crisis” of the book “Lead Wars: The Politics of Science and the Fate of America's Children” by Markowitz and Rosner, the lead poisoning and the actions taken is discussed. In the early 1900’s, health departments throughout the U.S. were not communicating and helping each other to fight the public threat of lead. Therefore it was easy for the Lead Industries Association (LIA) to downplay the impact of lead and for manufactures to avoid regulation. Paint was…

One of the qualities of lead that make it one of the most highly studied heavy metals is its ability to enter and distributes into the body’s organ systems. Inorganic lead is absorbed by coming into contact with the skin, ingestion, and inhalation.* It is debated whether ingestion of lead or inhalation of lead caused the most significant damage and which one occurs more frequently. The physiological effects of lead can be seen soon after exposure. The uptake of lead in the body is influenced by…

Lead, or Pb2+, is a naturally occurring toxicant, which was used in lead-based paints. The impact of lead poisoning in adults is far less serious than it is on child exposed whilst still developing. Pb2+ has the ability to pass through the blood-brain barrier as well as through the placenta into a developing fetus. A pregnant woman exposed to small amounts of lead that may not harm her leads the way for long-term effects on the child’s learning and memory due to the blocking of NMDA receptors in…

and information in a multilevel world sums up all the articles. It illustrated evidence that dynamic linkages across levels are more successful in assessing problems and finding solutions that are more politically and ecologically sustainable. Which can be associated with all the articles because in some way each issue that they addressed was involved in different elaborate levels to assess and solve their problems. The following papers were concentrated the elaborate cross-scale dynamics of…

of International Medical Research explored the effects of a thiamine and zinc combination supplementation treatment on lead poisoning (Flora, Singh, & Tandon, 1989). The hypothesis was that a mixture of the two would treat lead poisoning better than just thiamine or zinc alone. Measuring the lead concentration of rats who were exposed to just lead, thiamine and lead, zinc and lead, or all three and analyzing and comparing the results was the objective of this experiment. It was anticipated…

exactly what has happened. Lead as seeped its way into the water supply of this very big city. More information of this tragic incident can be found in five articles by CNN. They are called “How to test for lead in your home water supply.”, “Lead poisoning. Living with it and uncertainty of how long.”, “Water Crisis: Families bear scars from man-made disaster.”, “5 months later in Flint, high lead levels remain.”, and “How to help with Flint water crisis.” “How to test for lead in your home…

consequences and possibly lethal; lead poisoning is a top environmental health issue for children. Picher, Oklahoma fell victim to the devastation that can be caused by lead poisoning. Zinc and lead were major resources available in Picher making it a booming mining city. During the early 1920’s, lead exposure was not a high priority concern. Consequently, miners were dumping the waste from mining in the form of hills on the streets. When miners were digging up the lead and zinc, they were…
