On May 19, 2007, the Ministry of Agriculture, Forestry and Fisheries confirmed the occurrence of H5N1 in Hunan Province and urged the slaughter of more than 11,000 poultry. The provincial government immediately imposed an emergency plan and culled 52,800 birds to prevent disease spread. This was the first epidemic that occurred in the country in the first three months. Millions of farmers live near billions of chickens across this vast country. It is not surprising that birds and humans continue to get sick under the environmental conditions throughout China.
Throughout history, Chinese people have depended on the water that her seven major rivers are supplying for life. However, in the past 20 years, water quality has deteriorated to a serious condition. The Yellow River, which has been recognized for a long time as the birthplace of Chinese civilization, has been used very much for consumption, irrigation and factory production, so the amount of water flowing through this river is traditionally It is getting less. According to the World Bank's report released in 2001, 40% of the Yellow River's large watershed is classified as "not suitable for contact with humans" "China: the atmosphere for the New Millennium, Land, irrigation, agriculture ". (1)
The list of river pollutants includes industrial chemicals, heavy metals, dead animals, untreated human excrement. If this is combined with nuclear waste from millions of dead chickens contaminating raw water and groundwater in Tibetan rivers, it will be a matter of time before further human damage in China will occur.
China's National Environmental Protection Agency reports that industrial farms are a major cause of pollution. In 1995, more than 1.7 billion tons of untreated fertilizer was dumped into a river as a source of water. (2) In China's second river, the conditions of the Yangtze River are almost the same. Every year, more than 23.4 billion tons of sewage and industrial waste are disposed of in the Yangtze River. More than 15% of the water samples collected from the Yangtze River in 2001 were reclassified as "inappropriate for human contact". That percentage has certainly increased since 2001 and will continue to rise with the Westernization of Chinese culture.
Inflow of rural farmers into the city has expanded sewer infrastructure beyond capabilities. The operators of most new buildings report that the structure is connected to the sewer, but the waste is not being processed. Up to 80% of untreated sewage is still released directly to the water supply. (3)
Liaocheon in the northeastern part of China is the main waterway flowing from Shenyang, the capital city of Liaoning Province, to the Yellow Sea. In 1999, this river was classified as "suitable only for industrial purposes without human direct contact with water". (4) Indeed, it is far contaminated in 2007. It is not surprising that Liaoning Province has been a large outbreak place in many reported avian influenza and poultry in bird flu over the past three years.
Beyond the serious problem of contaminated water, China is located in nine cities out of the ten cities recognized as having the worst air pollution in the world. According to the report of November 1999 by the World Resource Institute (Urban Air Pollution Risks to Children) in November 1999, the respiratory illness associated with air pollution is between children and adults throughout China It is the first line of cause of death. Chronic obstructive pulmonary disease (COPD) and pneumonia in adults and children are major causes of death, respectively. (Five)
Air pollution is caused by the health conditions of millions of Chinese people, such as lung cancer and the reduction of immune function. Because Yunnan women recorded the highest incidence of lung cancer in South Africa, it is extremely bad, so 125.6 females per 100,000 females. This is compared with the national average of 6.3 lung cancer per 100,000 female top females in the United States. (6)
Symptoms and diagnosis of patients who have been confirmed to be infected with avian influenza after being hospitalized at the hospital are cataloged by WHO. All patients had symptoms of fever, cough, dyspnea, pneumonia. Conditions for developing pneumonia can include inhaling smoke and other toxic suspended particles. To drive out traffic jams, excessive mucus must be generated and a perfect environment for quick replication of the inviting group is necessary. If mucus contains a mixture of dioxin and other chemicals, the possibility of death from the influence may be exponential.
Considering that chronic lung disease and pneumonia are one of the most common causes of death in China, the identification of H5N1 may be of little relevance to its death. Perhaps their cause of pneumonia was complex environmental toxicity due to the presence of H5N1.
Hundreds of millions of poultry and ducks have been killed over the past four years, but the epidemic continues throughout China and Southeast Asia. Until a fundamental cause is revealed, poultry and human epidemics will undoubtedly continue until a large-scale environmental cleanup is carried out.
