Throughout the Yangtzi River Triangle, the southern region of China is famous for the production of rice that is widespread. Before they were several feet high and changed to golden brown, grass, soaked in a waterfront that is full of mud for many months. According to the rows of plants that are submerged under the water, the dam is collected and distributed to the continuous source of water, which the source of farmers from nearby canals
The traditional training of the flooding frogs to raise the level of growing famous plants is almost as old as the production of ancient cereals. Thousands of years later, the agricultural methods still have superior power to cultivate rice from the low fields of Archon Seo to the balcony that spread the branches of Vietnam.
While the planet is hotter, the process that is popular in rice planting is becoming more dangerous for millions of people around the world. research Published on Wednesday in the Journal of Lancet Planetary Health. After drinking water, the researchers said that rice is the second largest food source of organic rats and climate change seems to increase the amount of high toxic chemicals in it. If there is nothing to do to change the method of producing most rice in the world, how much IT people consume or reduce global warming. The author concluded that the community with heavy food can start to face the increased risk of cancer and disease for 2050.
“Our results are very scary,” Doning Wang, a Ph.D. student, the ecological system of the Chinese Science Institute of Science, which is the leader of the article. “It is a disaster … and the wake -up call”
Back in 2014, the Wang and a team of climate scientists, climate, factory and foreign public health began to work together in the research project that will end by approaching the past century. Going through the rice fields across the triangle, the Yangtze river, they try to find out that the temperature and level of the CO2 atmosphere in 1990 will interact with the rat in the soil and rice plants that are grown there. They knew from the previous research that carcinogens were problems in rice plants. But want to find out how warm the problem may occur in the world The team didn't only watch rice. But some rice varieties that are produced and consumed around the world the most
Even with blood vessels About 40,000 types of rice On the planet, they tend to be treated in three categories according to the length of the grains. Short grains or sticky children are often used in sushi. Long beads which include aromatic types such as Basmati and Jasmine; And the middle tablet or rice that is likely to be Act as the main dish– These are short to medium -term japonica and the long Indica tablet is Two important sub -species or cultivated rice Eat all over Asia The study of the palace is the growth model of the 28 species of Japonica, Indica and hybrid rice species that are the center of food for seven rice in the rice consumed and the country of seven countries: Bangladesh, China, Indonesia, Myanmar, Myanmar, Philippines and Vietnam. India, Vietnam and China are one of the groups of Eight That leads to the rest of the world to export rice
After almost a decade of observation and analysis of the growth of plants, the researchers discovered that the combination of higher temperatures and CO2 promoted the growth of roots, increasing the ability of rice plants to absorb the arsenic from the soil. They believe that this is because of the changes related to climate in the chemicals of soil that I like to easily absorb into the grains. Found that plants that are rich in carbon dioxide found that there are more carbon atmosphere and some pumps in the soil stimulate the microbes that make arsenic.
The more the growth of the roots, the more carbon in the soil, which can be a food source for bacteria in the soil that is multiplied under a warm temperature. When the soil in rice is recorded, oxygen will run out, causing bacteria in the soil to rely on the rat to create energy. The result is to create more arsenic in rice and other roots that will lead to the development of cereals.
The accumulation of these arsenic is linked to the growth of the roots and the carbon capture is a surprise that conflicts with the Corrux lessons, the Dart Mount College, posts and non -user research. Lesk conflicts say that these results are said to be useful that may occur with rice products under the change of climate. ” More roots can make the drought rice more drought and cheaper carbon can increase productivity in general, “he said.” But the accumulation of special rats may make it difficult to realize the benefits of health. “
There are many forms of arsenic. The arsenic that is sootenic inorganic – the compound of carbon -free elements – is what the World Health Organization Classify If “carcinogenic confirmation” and “the most important chemical contaminants in drinking water around the world.” The form or arsenic is In general, it will be more toxic. For humans, because they are less stable than organic pairs and may cause arsenic to interact with the molecules that disappear from touch. Chronic touch is linked to lungs, face and skin cancer, as well as heart disease, diabetes, unwanted pregnancy, neurodevelsopmental problems. And the immune system that occurs in the midst of other health impacts
Scientists and public health experts have known each other for many years that the appearance of arsenic in food is an increased threat. But getting a long bone food is considered less risky compared to the contaminated groundwater. Therefore, policy measures to reduce the risk slowly. For example, there are a few standards that have been announced by the European Union and China, which is considered inconvenient and does not come into effect. No country has officially established regulations for exposure to organic substances in food. (In the United States, the Food and Drug Administration has established The level of 100 parts per billions of organic rats in the rice grains for babies.But the advice for the manufacturer is not a rule that is enforced with rice substances in rice or other foods)
Wang Wang to see this change. The level of arsenic that is common in rice today falls into the recommended standards of China. But her paper shows that the face for life and the incidence of lung cancer tends to increase. “Proportion”, the 2050 touch under the “worst” level ” 200 parts per millionThe level of organic substances in the study of rice species is expected to increase by 44 percent. This means that more than half of the rice samples are exceeding the current limits of China, which are limited to 200 billion per billion for organic substances in rice paddy, with approximately 13.4 million cancer that is linked to the contact of rice in rice.
Because these health risks are calculated from the weight of the baby and young children will face the largest health burden. In particular, babies may face the risk of consumption of rice cereal as the researchers said.
“You are talking about the main raw materials of billions of plants that raise billions of people and when you consider that carbon dioxide and the hotter temperature will affect the amount of rats in many main raw materials, affecting the relevant health.
But everyone should not stop eating suddenly, he added Although the team will find the amount of organic substances in rice than many other plants, it is still quite low. How many important variables are rice to eat? If you are one of the worlds that eat many times a week, this health burden can be used with you. But if you do periodically, ZISKA says that inorganic rats that you may get “big stories”
In this way, the predictions of education may make the world inequality and society that exists more deeply due to the great reasons. Rice has been occupied for a long time that it is one of the world's most eaten grains, because it is one of the most inexpensive prices.
Aside from the relief of greenhouse gas emissions around the world – what ZISKA is called “I waved my rainbow and sprinkled the staff” – the effort to adapt to avoid the future rice.
Irrigation techniques for saving water, such as legislation and alternative drying, which have the first flooded rice fields and are allowed to dry in this round, can be used to reduce these increased health risks. and The large footprint of the rice seed On the global level, rice production has approximately accounting. 8 percent of all methane emissions from human activities – The rice fields that are full of floods are the perfect condition for Bacteria that are emitted–
“This is an area that I know is not sexy, which has no atmosphere like the end of the world, higher sea level, category 10, storm,” Ziska said. “But I will tell you honestly that it will have the most effective in terms of humanity because we all eat.”
