Waste of biodegradable plastic produces greenhouse gases

The plastics used in everyday items from water bottles to packaging produce greenhouse gases when decomposed in nature.

This study, published in the August 1 issue of PLOS ONE, raises concerns about the impact of this phenomenon on climate change.

Plastic waste at the waste treatment plant in Berlin, Germany.

American and Canadian scientists conducted experiments with plastic bottles, shopping bags, industrial plastics and food containers. Among these, the most harmful gas-producing component is polyethylene in the shopping bag, which is also the most produced and discharged synthetic polymer in the world.

Research indicates that resins produced when biodegradable produce strong greenhouse gases such as methane and ethylene. Greenhouse gases are believed to be the culprits that increase global temperatures, causing global warming and rising sea levels, threatening many coastal communities.

Although the emissions of decomposed plastic are not yet calculated, the authors say that it is necessary to come up with a specific number soon when the Earth now faces more than 8 billion tons of plastic waste and the amount of plastic produced. Ants doubled in the next 20 years.

Previous studies have shown that since 1950, more than 9 billion tons of plastics have been produced, most of which are discharged into the environment or buried. According to another study published in March last year, the giant trash island – where plastic waste gathers in the Pacific – is 16 times larger than the previous estimate, threatening marine life. Plastic waste has long been known to be a source of toxic chemicals that penetrate soil and water, causing harm to human health.

How to prevent stroke

According to Prof. Dr. Pham Gia Khai – Chairman of Vietnam Heart Association, preventing the formation and dissolving blood clot is a measure to limit stroke. Accordingly, patients need to pay attention and apply this principle of treatment.

Stroke is the third most dangerous disease after heart disease and cancer. According to research results published in the Lancet Medical Journal, in the past 20 years, the number of people suffering from strokes between the ages of 20 and 64 has increased by 25%. People under the age of 75 now account for 62% of new strokes, of which 45% are fatal, and 72% fall into illness and illness.

The study found that in 2010 alone, 61.5% of people were sick and 51.7% died of hemorrhagic stroke, which occurs when a weak blood vessel is broken and the cause It is caused by high blood pressure and unhealthy lifestyle.

Fermented soybeans

Enzyme Nattokinase in fermented soybeans, a traditional Japanese dish has created a new step in preventing and supporting treatment of stroke.

Professor Pham Gia Khai said that a stroke could occur at any time and is very fatal if not treated promptly. The disease is common in people with risk factors such as hypertension and diabetes. The cause is atherosclerosis, causing the vein to become narrow, easy to clog a clot, or fragile vascular walls, causing bleeding. In it, blood clots were identified as the cause of 80% of stroke.

When a blood clot appears, it causes a blockage of blood flow, causing an interrupted blood circulation, causing brain ischemia (cerebral infarction). When the blood is lacking, the brain stops working and dies within seconds to minutes. At this time, patients suddenly dizzy, lose balance, headache with unknown causes, have reduced vision, speak hard, weak or paralyzed one side of the limbs, paralyzed half of the body … The treatment is only effective maximum within the first 3 hours of the first signs of a stroke.

To avoid the unfortunate consequences of stroke, people with risk factors such as hypertension, unraveling sugar, dyslipidemia, obesity should actively prevent this dangerous disease. Sharing about effective prevention, Professor Pham Gia Khai said: ‚ÄúStudies show that preventing the formation and dissolving of blood clots is the primary measure to prevent seizures. Brain”. According to the doctor, in addition to implementing a lifestyle, scientific mobilization, reasonable, patients can also use food to help break down blood clots to minimize the risk factors leading to complications. cerebrovascular.

Currently, science has proved that nattokinase enzyme, fermented soybean extract has the effect of preventing and destroying blood clots – a major cause of stroke. This enzyme has been introduced into some products such as NattoEnzym with nattokinase ingredients originating from Japan.
