Are you heading for a Ngagne Diaw bis? The situation is fine. Lead is one of about ten products monitored by the World Health Organization (WHO) because it causes major health problems, according to Mamadu Fall, head professor at the Center for Anti-Toxicity. In 2008, due to intense activity on the subject, several children died of lead poisoning in the Diau district of Engagen in Surrey, Thierry. A public health problem that risks recurrence. The health authorities have no information to measure the extent of the damage caused by this product. One thing is clear, according to the head of the Poison Control Center, there are risks, due to the presence of lead in activities such as recycling car batteries and using paint, some of which do not meet the standards. He was asked yesterday, Thursday, June 9, during an information and awareness meeting on the quality of lead content limitations in paint. Senegal still does not have laws governing lead use.
How widespread is lead infection?
In Senegal, we don’t know the amount because there is no control, let’s control. On the other hand, in 2009, however, the analyzes we conducted in Paint found that 76% of the samples contained very high levels of lead. Since then, no new research has been done, although we have just finished pilot work. Of the 15 samples, only one had a very high rate; Which means that lead paint is still in vogue in our country.
What is the effect of lead on human health?
Health effects are even greater in children than in adults. But, since the consequences are very serious in the child, the whole world wants to work for him. It is a product that affects the child’s nervous system, reducing his intelligence, that is, mental development, learning and memorization. If a child is born with very high lead levels, it will not be unusual for him to have difficulty in school. Even more serious, it can cause other mental illnesses that will affect its development. The consequences are similar for adults. It is a metal that affects all organs, be it the nervous system or the kidneys. It can increase the pressure on the heart. It has been found that it is a product that can alter the fertility of men, altering sperm. Why is it said that 90% of the lead that infects the human body is found in bones? It is a metal that accumulates in the body, meaning that if taken in small doses today, it will be distributed in the body and 90% of it will be absorbed by the body. For a long time. If exposure continues, lead levels will increase throughout life. Even if a treatment is given, it can only eliminate lead in the blood and organs. And once the processing is done, there is a balance. The lead in the bones will begin to redistribute into the body, and once exposed, it will be extremely difficult or even impossible to remove all the lead from the body; So resistance is needed, so that we do not come in contact with lead derivatives. This can be done by avoiding the use of lead paint.
Recycling automotive batteries is a cause of pollution. In terms of the development of activities in the country, can we say that the risk of pollution is much higher?
Wherever we repair car batteries, we will have lead dust emissions. And where we try to melt lead, there is inevitably a puff of smoke. It is found in some places in Cologne. A study has shown us that both mechanics who recover these batteries, but also women who try to melt lead and convert it into fishing lead, are very exposed. And inevitably, if we use it anywhere, we will pollute the whole environment and expose the surrounding population.
In addition to reusable batteries, are there other materials that encourage lead transmission?
In general, when working with heavy metals, there are always lead marks. Be it the workshop of metal carpenters or others. These are weak traces, but they can reveal individuals in the long run.
Can we get lead in our food?
This is possible because lead has polluted the universe. But, we need to find very low concentrations. If lead is taken, only 5 to 10% will enter the bloodstream. On the other hand, through breathing, we can pass up to 50%; That is why air pollution and lead dust are much more dangerous. Everything should be done to ensure that the lead concentration in our diet is the most acceptable concentration.
More than ten years after the lead contamination, can we still talk about the Ngagne Diaw case?
Ngagne Diaw, more than 10 years ago. Since then, of course, there have been no deaths due to this lead, but contaminated children need to be followed. Since then, we, at the anti-poison center level, have not followed up because we have no way of doing it. However, we have no warnings that tell us that children are still at risk. On the other hand, the lead levels we got on these children in 2008 made sure that there was something in their bodies right now because the elimination was so slow. If we had lead in our bones, half would disappear after only 10 to 20 years. This means that if a baby had too many lead levels, without treatment, there would always be the same level of infection.
What about the risks posed by those who have settled on the site?
The site was cleared by environmental teams. We removed tons of products that we kept elsewhere. And in principle, the site is much less corrupt. However, follow-up is required. Even if it is done, it is always good to tell people where to go. We are talking about Ngagne Diaw, but I am sure there may be other places where the contamination may be much higher because it is not checked. What is important is that everyone understands that there are different sources of lead exposure and that where each Senegalese is, they understand the risk. We expect a lot from the state, but the risk comes from the population. If everyone is involved, we can reduce the risk of infection from lead but also from all other chemicals.
