37, March 16, 2005 KFC belongs to Yum Brands in Shanghai issued a public statement announcing that Kentucky Chicken New Orleans wings and New Orleans baked chicken thighs burger seasoning in the 15th inspection was found to contain Sudan red (No. 1) ingredients, the domestic all KFC restaurants immediately stop selling these two products, while destroying all seasonings. It turns out that Sudan Red is not a food additive. Rather, it is a chemical coloring agent, and its chemical composition is a compound called naphthalene, which is also a man-made chemical agent. Sudan red belongs to the azo class of chemical colorants, mainly used in solvents, waxes, gasoline color enhancement and shoes, floors and other lightening.
Studies have shown that Sudan Red 1 is carcinogenic, causing cancer in rodents, and it has also been shown to be carcinogenic in human liver cell studies. Because the dye, which is used as a food coloring, only slowly affects the health of those who consume it and does not rapidly cause cancer, it is highly insidious. "After degradation by the human body, Sudan Red No. 1 forms a moderately toxic carcinogen called "aniline". Excessive inhalation of "aniline" into the human body may cause tissue hypoxia, poor respiration, central nervous system, cardiovascular system and other diseases. If inhaled in excess, aniline may cause tissue hypoxia, poor respiration, damage to the central nervous system and cardiovascular system, and even lead to infertility. Animal experiments show that "Sudan Red 1" can lead to some cancers in rats, but it is not a serious carcinogen, so don't panic too much. Sudan red is mainly used (so far found): chili sauce, chili oil, spicy radish, soy sauce, curd.
According to the above information, please answer:
(1) What kind of substance is "Sudan Red 1"? Why did it cause concern to the whole society?
(2) What do you know about food safety after reading the material? What do you learn from it (about food safety)?
(3) What do you think should be done to control the food problems caused by this kind of substance?
38、According to reports, most people in a village in Yingde City, Guangdong Province, live to be no more than 40 years old. The province's Geological Survey Institute was informed of this and carried out a geological survey of karst groundwater resources exploration and ecological environment in northern Guangdong. It was found that due to the low-lying terrain, the sewage seeped into the ground and polluted the groundwater resources, so that the manganese content of the groundwater was up to 0.65 milligrams per liter, and the nitrite content was up to 0.15 milligrams per liter, which exceeded the national drinking water hygiene standards by 6.5 times and 30 times respectively. As a result of the long-term recycling of polluted water, the health and life of local people have been seriously affected. It can be seen that human activities affect the environment, and changes in the environment affect the survival and development of human beings themselves. Please answer in the light of the local ecological environment, production or actual living conditions:
(1) Give an example of human activities that damage the ecological environment.
(2) Ask an exploratory question about the example.
(3) Make a hypothesis using prior knowledge.
(4) State the methodology of the probing question.
(5) Make suggestions for solving the problem.
