Why has drinking water standards fallen instead of rising in the past 30 years?

On May 24, the "National Food Safety Standard for Packaged Drinking Water" was officially implemented, standardizing the "concept water" and adjusting the microbial indicators. What changes will the new national standard for drinking water bring to our lives? For "conceptual water", the standard clearly stipulates that the name of packaged drinking water shall be true and scientific, and shall not name packaged drinking water with one or several components other than water, and shall not be marked with "activated water", "small molecule water", "functional water", "energy water" and other unscientific content.

The standard clearly states that it applies to packaged drinking water for direct consumption, but not to drinking natural mineral water. This means that in the field of drinking water, there will be at least three categories of drinking pure water, natural mineral water and other drinking water in the future, and "concept water" such as mineral water can no longer be "capricious", while soda water, dry ginger water and other beverages are not within the scope of the new national standard, and the naming will not be affected. In the new national standard, what has attracted much attention is the change of microbial indicators, which no longer retain the total number of colonies, mold and yeast counts, Staphylococcus aureus, Salmonella and Shigella, and add Pseudomonas aeruginosa indicators.

The elimination of the total number of colonies indicator does not mean that the water quality is reduced.

Because technology is getting better and better, the economy is getting better and better. But correspondingly, it is necessary to sacrifice a certain environment to promote economic development, such as more and more enterprises opening factories to discharge pollution. This will cause a certain amount of environmental damage, and the awareness of people who protect the environment is not good.

At present, the miscarriage rate of women is increasing year by year, and some women have more than one or two miscarriages, as long as they find out that they are unexpectedly pregnant, they choose to have an abortion operation, and multiple miscarriages also lead to great damage to the endometrium, and the fallopian tubes may also be blocked, which virtually increases the difficulty of pregnancy. It is hoped that young women must take contraceptive measures during sex to avoid unwanted pregnancies.

3. Wear too little.

Many women in the cold winter to demeanor not temperature, clothing is still very thin, so in the long run will become uterine cold, greatly reducing the chance of pregnancy, so I hope that female friends must pay attention to keeping warm in winter.

Natural selection, survival of the fittest. The mosquitoes of the Arctic Circle are not the same species as the mosquitoes in the northern temperate zone where our country is located, and the mosquitoes of the Arctic Circle have better cold tolerance and are more able to survive and reproduce in the cold environment.

Mosquitoes have adapted to the local environment. These mosquitoes are generally mutated species that have been able to breed and survive in the local cold environment.

The reason why the Arctic Circle is so cold and the number of mosquitoes in the area is still so large is mainly due to the effect of the greenhouse effect. The greenhouse effect is becoming more and more serious due to the severe damage to the environment and the increasing amount of carbon dioxide released, so the hole in the atmosphere is getting bigger and bigger. Although the Arctic Circle is very cold, due to the influence of the greenhouse effect, permafrost and glaciers have begun to melt slowly, and the temperature has begun to rise.

Characteristics of mosquitoesMosquito this animal has a very high reproductive ability, it usually likes to breed in wetlands and shallow water, and the Arctic due to the impact of the greenhouse effect, let some permafrost begin to melt, and the shallow water and mud formed after the melting of ice and snow have become the best choice for mosquito breeding.

Mosquitoes are very afraid of cold but also very afraid of heat, the general temperature is about 20 degrees Celsius is the most suitable for breeding, when the temperature is lower than 10 degrees Celsius or higher than 35 degrees Celsius, the mosquito's reproductive ability will be reduced, the winter is too cold, mosquitoes will hibernate. However, in recent years, the temperature in the Arctic Circle has been very high in winter, and this year it has exceeded 20 degrees Celsius, so the mosquitoes are over-breeding, so there are a lot of mosquitoes in the Arctic Circle.

The Greenhouse EffectIn addition to raising the temperature of the earth, the greenhouse effect will also make the summer hotter and hotter, and the winter will become colder and colder, and the melting of large areas of glaciers will lead to the rise of sea level, and some lowland cities or rice fields will be submerged, and human habitat and food will be reduced. Billion-year-old viruses are being released from the permafrost, and terrible infectious diseases are about to be swept in.

Large areas of rice fields are salinized, no longer suitable for growing any crops, more and more people have no food, and they may freeze to death in winter and heat in summer, in short, the earth's environment will become more and more unlivable.

There are different species of mosquitoes, some mosquitoes are cold-tolerant and some mosquitoes are heat-resistant, I am in the southern region, and the mosquitoes here are very heat-resistant, and the mosquitoes in the Arctic Circle may be cold-tolerant.
