The advantage of this technology is that it is very gentle.” With regulatory considerations in mind, the lab group is “moving toward commercialization” with a $50,000 grant to scale up the technology to treat large volumes of water, Liu said. The scientists plan to put short-wave ultraviolet light into treatment tanks. Liu notes : “We are optimizing the technology, trying to make it universal for a wide range of waters contaminated with PFAS. The technique has shown very promising results in the destruction of PFAS in both drinking water and various types of waste.” Scientists have found that the ozone hole over.
Antarctica has shrunk compared to last year. Let's talk about what it whatsapp mobile number list means What's happening Researchers from NASA and the US National Oceanic and Atmospheric Administration found that in October 2022, the size of the Antarctic ozone hole was approximately 23.2 million km². This is 1.6 million km² less than last year: in 2021, its area was 24.8 million km². According to the chief researcher of the Earth Sciences Department of the Space Flight Center. Goddard at NASA, the ozone hole has shrunk over the past two decades. is the Dobson spectrophotometer.
It allows you to calculate the total ozone content in the vertical column of the atmosphere. The global average is about 300 Dobson units (1 Dobson unit is equal to 0.01 mm of ozone). On October 3, the minimum value of ozone over the South Pole was 101 units. Dobson. This is good news for the inhabitants of these latitudes, as well as those who live in the mountains and are subject to increased solar activity. What does it mean from ultraviolet radiation from the Sun. Places where the concentration of ozone is extremely low are called ozone holes. Back in 1974, scientists found that holes are formed as a result of the contact of sunlight with substances containing chlorine or bromine. At low atmospheric temperatures.
