電子煙和香煙哪個危害大?

Posted by dajksdhj21 on September 18, 2024 at 10:31pm 0 Comments

長久以來,關於電子煙和香煙哪個危害更大的討論未曾停歇。在全球範圍內,吸煙已被證明是導致多種嚴重健康問題的主要原因,包括肺癌、心臟病和慢性阻塞性肺疾病。隨著人們對健康的關注增加,電子菸作為傳統香煙的替代品逐漸流行起來。







電子煙和香煙哪個危害更大仍然是一個備受關注的問題,一起來看看,希望能幫到你。



傳統香煙通過燃燒煙草來釋放尼古丁,同時產生大量有害物質,包括一氧化碳、焦油和數千種其他化學物質,其中許多是已知的致癌物。長期吸煙者面臨著嚴重的健康風險,如肺癌、心血管疾病和呼吸系統問題。香煙的危害已被大量科學研究和公共衛生數據所證實。



電子煙則通過加熱含有尼古丁的液體(通常稱為… Continue

Nobel physics prize goes to 3 for climate discoveries

The Nobel Prize for physics has been awarded to scientists from Japan, Germany and Italy.

Syukuro Manabe (90) and Klaus Hasselmann (89) were cited for their work in “the physical modeling of Earth’s climate, quantifying variability and reliably predicting global warming”.

The second half of the prize was awarded to Giorgio Parisi (73) for “the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.”

The panel said Mr. Manabe and Mr. Hasselmann “laid the foundation of our knowledge of the Earth’s climate and how humanity influences it".

Starting in the 1960s, Mr. Manabe demonstrated how increases in the amount of carbon dioxide in the atmosphere would increase global temperatures, laying the foundations for current climate models.

About a decade later, Mr. Hasselmann created a model that linked weather and climate, helping explain why climate models can be reliable despite the seemingly chaotic nature of the weather.

He also developed ways to look for specific signs of human influence on the climate.

Mr. Parisi “built a deep physical and mathematical model” that made it possible to understand complex systems in fields as different as mathematics, biology, neuroscience and machine learning.

After the announcement, Mr. Parisi said that “it’s very urgent that we take very strong decisions and move at a very strong pace” in tackling climate change.

“It’s clear for future generations that we have to act now,” he added.

The winners were announced on October 5 by Goran Hansson, secretary-general of the Royal Swedish Academy of Sciences.

Last year, the prize went to American Andrea Ghez, Roger Penrose of Britain and Reinhard Genzel of Germany for their research into black holes.

The prestigious award comes with a gold medal and 10 million Swedish kronor (over $1.14 million). The prize money comes from a bequest left by the prize’s creator, Swedish inventor Alfred Nobel, who died in 1895.

On Monday, the Nobel Committee awarded the prize in physiology or medicine to Americans David Julius and Ardem Patapoutian for their discoveries into how the human body perceives temperature and touch.

Over the coming days prizes will also be awarded for outstanding work in the fields of chemistry, literature, peace and economics.
