The “highly high” exposure in the “1960s” may be exposed to the 1970s

Prepare for smoke.

Gasoline It has been widely used as a fuel for cars in the United States from the 1920s until the 1970s – gradually eliminated because it was found to be harmful to the environment and Human health.

It took decades to the toxicity of lead to completely understand. A new study adds to the dark news – if you live in a high -level area in the atmosphere between 1960 and 1974, when the gas that was at its peak, you would likely suffer from memory problems later 20 %.

“Research indicates that half of the United States population – more than 170 million people – have been subjected to high levels of early childhood,” he said. Maria Siarilothe Alzheimer’s AssociationThe chief science officials and the leadership of medical affairs.

“This research sheds more light on lead to brain health in the elderly.”

Lead was initially added to gas in the early twenties of the twentieth century to improve engine performance and prevent the sound that expels or a rift occurs when fuel burns uneven in the engine cylinders.

In the end, he was considered dangerous to maturity and nervous systems for young children, who suffered from developmental difficulties, learning and behavioral.

Adults faced nervous and reproductive issues, and soil and water pollution continued.

The sale of respected cars on the road has been gradually reduced in the United States over two decades, with a full ban in 1996.

For the new study, the University of Toronto researchers planned lead levels in the historical atmosphere in the United States.

They compared these data to memory difficulties that more than 600,000 of the 65 population and described from 2012 to 2021. The population was only included in the analysis if they lived in their condition.

According to the authors of the study, 17 % to 22 % of people in places of medium, high or high levels in the atmosphere have reported memory problems.

“When I was a child in 1976, our blood was 15 times more than Child blood today,” He said Esme Fuller-HomsonA great author of the study and director of the Institute of Life and Agency at the University of Toronto.

“88 % of the United States had higher levels of 10 micrograms per deciliter, which is now dangerously high.”

Researchers – who are doing their work this week in The International Conference of Alzheimer’s International Association (AAIC) in Toronto-recommended that those concerned to focus on a decades-leading leadership. Disk factors dementiaSuch as high blood pressure and smoking and Feeling lonely.

More than 6 million Americans suffer from dementiaWhich gradually destroys memory, concentration and judgment skills. It is responsible for more than 100,000 deaths every year.

Unfortunately, there is no easy way to measure long -term bullet exposure.

The levels of lead in the blood reflect in the first place modern or continuous exposure.

The bullets are stored in the bones for a much longer blood – but this sign represents the challenges.

“Some research studies measured lead in bones,” Dr. Eric BrownThe author of a leadership study, he told the Post.

“This is done using a technique called the KX-ray, however, it is not available to the general public and is primarily a research tool, not a clinical tool.”

What is more, Respected gas is still used In some cars aircraft and race – and Lead tubes and paint It remains a major concern for public health in many areas.

A separate joint study in AAIC revealed that exposure to bullets – even at low levels – can contribute to the abnormal Tau and Amyloid experimental accumulation, Proteins associated with Alzheimer’s diseaseIn brain cells.

Finally, another AAIC study found that the elderly who live about 3 miles from the lead facility-such as glass, ready-made concrete, computer and electronics manufacturers-face greater possibilities of memory problems and thinking problems more than those who live away.

“Our results indicate that exposure to bullets in adulthood can contribute to the worst cognitive performance within a few years,” he said. Catherine KonlonA great study and associate professor of environmental epidemics at the University of California, Davis.

She added: “Despite the tremendous progress in reducing bullets, studies have shown that there is no safe level of exposure, and half of our children have levels that can be discovered in their blood.”
