How Lead is common body contaminator

Humans use lead in their daily activities for 6000 years. In the past, simply use lead in the formation of trays. Kitchen utensils and decorative things. But lead is a very dangerous metal for a human being. It affects the reproduction system, urinary system. The lead effects man by exposure to water soil paints in kitchen utensils. It’s called lead poisoning.

Oral ingestion is the main reason for lead poisoning. If the level of lead increases in the body it causes lead poisoning, even a small quantity cause problems.

Children are more sensitive to lead poisoning. Mental and physical development affected by lead poisoning. A higher level of the lead cause of death. Paint and dust lead contain used in the older buildings are one of the common reasons for lead poisoning in the child.

But those people who work in auto repair shops in work with batteries might be affected by lead poisoning. Treatment of lead poisoning is also available but we should take some prevention measures to protect ourselves and our families from lead poisoning.

similarly, waste material of auto shops and lead manufacturing factories causing soil pollution.

Types of lead poisoning

Acute poisoning

In this type of lead poisoning, symptoms are a weakness of the muscles, pain, and brain inflammation that may occur. The mouth is also affected by lead poisoning. If a large quantity of lead exposes for a small period of time can cause the efficiency of fluid in the circulatory system.

Hemoglobin and Anemia and may occur in urine due to the rupturing of RBCs. This is caused by acute poisoning this condition is called hemolytic. Acute poisoning can damage kidneys due to which urine output level decreased

Chronic poisoning

It is a type of lead poisoning that affects many systems of the body. Intense lead exposure effect the neuromuscular and central nervous system. Lead exposure for a long period of time can cause symptoms of gastrointestinal problems. It causes sleep problems, anemia problems, pain in the head and abdomen, hypertension and fatigue, and loss of concentration.

Children are at high risk of lead poisoning as compared to adults because small bodies of children have continuous growth process  & absorption of lead is faster in children as compared to adults and it causes more damaging effects to children as compared to older peoples.

Children him more chance of getting lead into their body because during crawling and walking on the floor, they ingest and inhale lead-contaminated dust.

What are the Causes of lead poisoning

Lead is a naturally occurring metal present in the earth, crust. It is spread by human activities like fossil fuels burning and mining. In the past, lead was used in the formation of gasoline and paint but now in modern days Lead used in different materials like poultry, solder, roofing materials batteries, and cosmetics.

Symptoms of lead poisoning

Firstly, it is difficult to detect lead poisoning because some who have a high blood level of lead seem healthy. Symptoms appear at that time when a large amount of lead accumulated. So, this is why it is very fatal. Intellectual disability is affected by 10 %. That causes behavioral problems.

More risk of lead poisoning in the children because they get things in their mouth which have lead paint so a large amount of lead is absorbed in their mouth by eating such thing. Lead poisoning causes vomiting seizures, intellectual disability constipation.

Some further symptoms are irritability, loss of weight, delay in the developmental process, and fatigue and sluggishness, difficulties n the learning process.

Lead poisoning in children

Newborn babies have the following signs and symptoms of lead poisoning. Premature birth can occur. Newborn babies have very low weight and a very low growth rate. Adult also has the following sign & symptoms. They have high blood pressure and pain in joints and muscles.

They also have pain in the head and abdomen. Miscarriage and premature birth can occur during pregnancy. Basically different symptoms of lead poisoning occur which depend upon the individual and time period of lead exposure. Organic lead can affect the central nervous system.

How to diagnose the lead poisoning

During the routine checkups, the child must be tested to determine the level of lead in the blood. Lead poisoning can be detected by a simple blood test. Micrograms per deciliter are used for measuring the lead level in the blood. Children whose level in the blood is too high like 45 mcg/dl) then children must be treated.

A variety of lab and imaging tests can be used to diagnose lead poisoning. The blood level is the main test that gives us information about the level of lead in the blood. If there is no lead in the blood then it is an ideal situation and no need for treatment.

The range of lead levels in the blood of children less than 5 ug/ dl and for adults it is less than 25 ug/ dl but this test can give us information about the lead level in the blood it does not tell us about the effects of lead on the body.

Treatment options for lead Poisoning

Removal of the source of contamination is the first step of the treatment of lead poisoning. If we are not able to source lead poisoning which causes this problem then we not able to reduce the problem.

Chelation therapy

In this therapy, medication is given orally which attached with lead so, in this way it is removed in urine those children with a high level of lead, this therapy is used.

Conventional chelation therapy

It is used for adults because children cannot tolerate it. A chemical  ethylenediaminetetraacetic acid ( EDTA) used with chelation therapy by injection.

Side effects lead to poisoning treatments

Fever, Nausea, chest tightness, vomiting, headache are a side effect of chelation therapy. This chelation therapy is given through mouth or intravenously.

The complication to lead poisoning in children

High quantities of lead cause fatal effects in the children’s nervous system and the Kidney can damage due to a high level of lead. If lead increase at a very high level it may cause unconscious seizures and even death.  [1] [2]Lead toxicity: a review ( [3]9789241500333_eng.pdf ( [4]LEAD POISONING ( [5]The Lead Poisoning Words to Know from A to Z glossary (
