Discovering possible culprits of 4,000-year-old archaeological work in Mexico

Researchers warn that acid rain could become the "culprit" of destroying many valuable archaeological works in Mexico in the next 100 years.

According to experts, it is gradually destroying ancient monuments and temples in Mexico. Increased pollution that leads to acid rain can completely destroy many ancient Mayan sculpture archaeological works in the next 100 years.

Many researchers in Mexico warned that acid rain could "wipe out" some of the nation's historic heritage, including 4,000-year-old stone works .

Dr. Pablo Sanchez at the Center for Atmospheric Research at the National Autonomous University of Mexico, said: "In the next 100 years, all ancient texts on the walls and stone pillars may be lost."

Especially archaeological works, Mayan remains are built from limestone containing calcium carbonate (CaCO ₃ ) - a chemical that dissolves rapidly in acid rain.

Causes of acid rain: "Obsession" of archaeological works for thousands of years

Acid rain occurs because rainwater dissolves "toxic" gases such as SO ₂ , SO ₃ , N ₂ O, . and creates their corresponding acids, causing a low pH (<5). , 6).

The increase in the amount of oxides of nitrogen and sulfur in the atmosphere is mainly caused by human activities.

Acid rain has a great impact on the environment and ecosystem, destroying many materials made of metal such as iron, copper, zinc, . as well as reducing the life of many construction works and monuments. Stone history.

Mexico City has been "struggling" with pollution for decades and is considered the most polluted city in the world in 1992.

In fact, experts at ancient Mayan limestone monuments are trying to find solutions to cope with acid rain.

Rather than simply covering up a protective film, Dr. Sanchez said: "Limestone needs to be breathed, absorb moisture and water. Therefore, if covered, it could cause an increase in erosion. trail".

Scientists say, acid rain pollution may not necessarily arise in Mexico, because they can travel over very long distances in the atmosphere. Therefore, tracing the source of pollution is quite difficult.

The mystery is said to begin around 1800 BC and lasted until 1697.

This is one of the most mysterious civilizations in human history with many unknowns. Every year, many tourists come to this "promised land" to visit archaeological works, relics of ancient Mayan temples.

However, the acid rain situation has been "threatening" to the quality and longevity of projects bearing this cultural mark.

Not just ancient temples and monuments, but experts recently said that pollution and acid rain are also threatening.

According to the researchers, acid rain can corrode the thousands-year-old skeletons in caves.

This is newly mapped and considered the most important underwater archaeological site in the world.

Some of the antiquities found here date back to more than 12,000 years and many traces of the mysterious ancient Mayan make the scientific world astounding.
