Major gaseous pollutants and hazards in animal laboratories

Harmful pollutant gases such as stench, odor, VOC and other harmful pollutants produced by feed, bedding, animal hair and dander, as well as feces and urine excreted by animals in animal laboratories greatly affect human health, and at the same time interfere with the results of animal experiments:

-When the concentration of ammonia increases, it can stimulate the conjunctiva of the eyes, nasal mucosa and respiratory mucosa of the animals and cause tearing, coughing, and in serious cases, even produce acute pulmonary edema and lead to animal death.

-Laboratory disinfectants such as ethylene oxide, hydrogen peroxide, peracetic acid, glutaraldehyde, o-phthalaldehyde, etc. can be harmful to humans.

Major gaseous pollutants and hazards in laboratories

Laboratory-generated gaseous pollutants pose a major threat to the respiratory health of researchers

　　Problems encountered in cleaning the air environment in animal laboratories

At present, most animal laboratories generally have the following problems in air environment purification:

(1), before the construction of animal laboratories , the lack of laboratory exhaust volume, ventilation system for proper calculation and planning, resulting in laboratory operation, the preset exhaust volume and piping can not be fully loaded, to achieve the purification effect.

(2), the laboratory in the construction of the neglect of animal laboratories produce odor, odor problems, did not increase the chemical filtration section, resulting in laboratory operation, odor and malodor a large number of increases, can not be removed, not only affects the results of animal experiments, affecting the health of the animals, but also jeopardize the physical health of researchers.

　　It is urgent to improve the stench and odor of animal laboratory and take care of the respiratory health of researchers.

　　Laboratory safety standards and regulations:
