Disinfection refers to a method that kills pathogenic microorganisms but does not necessarily eliminate bacterial spores. Disinfection is typically achieved through chemical means. The chemical agents used for disinfection are called disinfectants. Sterilization, on the other hand, is a method that completely eliminates all microorganisms—including bacterial spores—from an object; sterilization is usually accomplished by physical methods. Antimicrobial preservation refers to methods used to prevent or inhibit the growth and reproduction of microorganisms. Chemical agents employed for antimicrobial preservation are called preservatives. Sterility means the absence of living microorganisms; it is the result of sterilization. The set of techniques used to prevent microorganisms from entering the body or objects is known as aseptic technique.
Veterinary drugs refer to substances (including medicinal feed additives) used for the prevention, treatment, or diagnosis of animal diseases, or for the purposeful regulation of animal physiological functions. Veterinary drugs mainly include: serum products, vaccines, diagnostic products, microbial ecological products, traditional Chinese medicinal materials, proprietary Chinese medicines, chemical drugs, antibiotics, biochemical drugs, radiopharmaceuticals, as well as topical insecticides and disinfectants.
The cell culture room is equipped with a biosafety cabinet, a CO2 incubator, an inverted biological microscope, and a low-speed refrigerated centrifuge, among other equipment.
Dedicated personnel manage the receipt, storage, distribution, and return of test samples and reference standards.
A cleanroom refers to a tightly sealed space in which parameters such as air cleanliness, temperature, humidity, pressure, and noise are all controlled according to specific requirements.
The development of agricultural industrialization has made the production of agricultural products increasingly dependent on exogenous substances such as pesticides, antibiotics, and hormones. In China, the use of pesticides in agricultural production remains persistently high. The irrational use of these substances will inevitably lead to excessive pesticide residues in agricultural products, compromising consumer safety. In severe cases, this can cause illnesses, abnormal development, or even direct poisoning and death among consumers. Excessive pesticide residues also pose a threat to agricultural trade. Countries around the world attach great importance to the issue of pesticide residues and have been setting increasingly stringent maximum residue limits for pesticides in various agricultural and sideline products, thereby presenting Chinese agricultural exporters with serious challenges. There are many types of rapid detection methods for pesticide residues. In terms of their underlying principles, they can be broadly categorized into two main types: biochemical assays and chromatographic methods. Among the biochemical assays, the enzyme inhibition assay stands out due to its advantages of being fast, sensitive, easy to operate, and low-cost. As a result, it has been listed as a nationally recommended standard method (GB/T 5009.199-2003) and has become one of the mainstream techniques for rapid on-site qualitative screening of organophosphorus and carbamate pesticide residues in fruits and vegetables, enjoying increasingly widespread application.
A chemical detector is a specialized safety and hygiene instrument used to detect the concentrations of flammable or toxic gases and vapors in the air at chemical workplaces or inside equipment, and to provide an alarm when these concentrations exceed the permissible limits.
Toxicological Evaluation of Pesticide Registration Trials
Pesticides are chemical agents used in agriculture to control pests and diseases, as well as to regulate plant growth. They are widely applied in agricultural, forestry, and animal husbandry production, environmental and household pest control and disease prevention, and the prevention of mold and insect damage in industrial products. There are many types of pesticides; classified by use, they can be mainly divided into insecticides, acaricides, rodenticides, nematicides, molluscicides, fungicides, herbicides, and plant growth regulators. Classified by their source materials, they can be divided into mineral-origin pesticides (inorganic pesticides), bio-origin pesticides (natural organic substances, microorganisms, antibiotics, etc.), and chemically synthesized pesticides. By chemical structure, they mainly include organochlorines, organophosphates, organonitrogens, organosulfurs, carbamates, pyrethroids, amide compounds, urea compounds, ether compounds, phenol compounds, phenoxy carboxylic acids, amidines, triazoles, heterocyclic compounds, benzoic acid compounds, and organometallic compounds—all of which are synthetically produced pesticides. According to their formulation type, they can be categorized into powders, wettable powders, emulsions, emulsifiable concentrates, creams, pastes, colloidal formulations, fumigants, fumigating agents, smoke agents, granules, microgranules, and oil formulations, among others.
