There are two problems in the above traditional detection methods: one is that the measured components are difficult to cover all substances that may endanger human health, which often leads to missed detection; the other is that if there are many harmful components in the measured gas, the harmful components may interact To enhance the toxicity, so that the content of each harmful component does not exceed the standard, but in fact the measured gas will still endanger human health after being inhaled into the human body

Embodiment 1
[0021] The safety of biological samples to detect formaldehyde gas. The present embodiment is by measuring biological sample oxygen (chemical formula O 2 ) flow rate changes to determine the safety of formaldehyde gas.
[0022] (1) The whole water worm (Limnodrilushoffmeisteri) was selected as the measurement sample. Waterworm is a common freshwater benthic organism that can be used as bait for fish.
[0023] 1 liter of formaldehyde (CH 3 OH) gas is dissolved in 1 liter of normal saline to make a solution, which is used as the measured water source; 1 liter of clean air is dissolved in 1 liter of normal saline to form a reference water source. Water silk worms were placed in the reference water source and cultivated for 24 hours, and then the whole oxygen molecules of water silkworms (O 2 ), measure a data every 6 seconds and measure for 10 minutes, and take the average value of the data obtained during this period as the reference water source flow rate value J 1 , the m...
Embodiment 2
[0036] The safety of nitrogen gas in the detection of biological samples. In this embodiment, by measuring the biological sample hydrogen ion (chemical formula H + ) flow rate changes to determine the safety of nitrogen.
[0037] (1) Chlamydomonas reinhardtii (Latin scientific name Chlamydomonas reinhardtii) is selected as the measurement sample. Chlamydomonas is an aquatic eukaryotic single-cell organism that is widely distributed in ditches, depressions or other small water bodies containing trace organic matter. It can be eaten by humans and can also be used as feed for poultry.
[0038] At normal temperature and pressure, 1 liter of nitrogen (chemical formula N 2 ) was dissolved in 1 liter of normal saline to make a solution, which was used as the measured water source; 1 liter of clean air was dissolved in 1 liter of normal saline to form a reference water source. Place Chlamydomonas reinhardtii in the reference water source for static culture for 24 hours, then measur...
Embodiment 3
[0049] Biological samples are used to detect the safety of indoor air in houses after decoration. The present embodiment measures biological sample calcium ion (chemical formula Ca 2+ ) to detect the safety of the indoor air in the house after decoration. In this example, five biological samples, including crucian carp embryos, human oral epithelial cells, root tips of Arabidopsis thaliana, rat liver, and Saccharomyces cerevisiae, were selected, and experiments were carried out on an ordinary family house that had just been renovated.
[0050] (1) Experimental results of crucian carp (Carassiuscuvieri) embryos. Crucian carp is a very common edible fish in my country. During the development of crucian carp embryos, there will be an influx of external calcium ions to assist them in completing their development. In this experiment, 6-day-old crucian carp embryos were selected as samples.
[0051] In a room of an ordinary family house that has just been renovated, 1 liter of a...

Abstract
The invention discloses a method for distinguishing gas security through the ion and molecule flow speed of a living body. The gas biosecurity is distinguished by utilizing the sensibility of the living body to substances, which are poisonous and harmful to the environment, formed in the long-term natural evolution process. The life science research shows that the reaction of the living body to the poisonous and harmful substances need to follow changes of the related ion or molecule flow speed, and therefore the biosecurity after measured gas is sucked into a human body can be judged through comparison whether the living body ion or molecule flow speed of a benchmark water source dissolved in clean air and a measured water source dissolved in the measured gas is obviously changed or not. According to the method, the defects that the poisonous and harmful substances in the gas possibly cannot be detected due to omission, the derivative poisonous effect caused by interaction of various substances (comprising the poisonous and harmful substances) in the gas cannot be represented in a traditional method are effectively overcome.
Description
technical field [0001] The invention relates to a method for judging gas safety through the flow rate of biological ion molecules, is a biological detection method based on the physiological characteristics of biological samples, and belongs to the technical field of environmental detection. Background technique [0002] Air is an indispensable substance for life activities and is closely related to human health. For the safety of gases that may be inhaled into the human body, governments around the world have formulated a large number of mandatory testing standards or specifications. The current gas safety standards determine the safety of gases by detecting whether a series of chemical components that may be harmful to human health exceed the specified threshold. There are two problems in the above traditional detection methods: one is that the measured components are difficult to cover all substances that may endanger human health, which often leads to missed detection; ...
