Research by scientists from Canada shows us that urban dust not only pollutes at the mechanical level but also at the chemical level.

Katherine Ensor, a statistician at Rice University in the United States, and colleagues analyzed data on more than 11,600 people who experienced a heart attack in Houston, Texas,

Scientists at the University of Science (Thai Nguyen University) have successfully applied the method of using strong oxidizing ozone agent to treat persistent organic compounds in

According to scientists, ozone holes have recently appeared in the Arctic region. At an altitude of about 20km from the ground, ozone concentrations decreased by 80%.

Scientists discovered ozone holes in Antarctica that are in the process of self-sufficiency, at least a decade earlier than they had previously expected.

The pieces of dead skin combined with dirt can help reduce 2 - 15% of toxic ozone levels that appear in the enclosed environment inside the house.

In the most recent report, international efforts to prevent the destruction of the ozone layer have achieved initial success.

The ozone layer is tending to be very small and is able to restore the situation in 1980 in the middle of this century, according to a recent report by UN scientists.

Vietnam has achieved remarkable results in gradually restricting the use of ozone depleting substances.

World Meteorological Organization (WWO) predicts ozone depletion in Antarctica, this year, is likely to be smaller than the loss in 2008.
