What are the detection methods of compound gas detectors?
(1) Occupational poisoning can be caused by productive toxins. Occupational poisoning can be divided into three types according to the onset process. Acute poisoning: caused by a large amount of toxic substances entering the human body in one or a short period of time. Most of them are caused by production accidents or violations of operating procedures. Chronic poisoning: Chronic poisoning refers to the long-term entry of small amounts of toxic substances into the body. The vast majority are caused by accumulated toxins. Subacute poisoning: Subacute poisoning is a poisoning phenomenon that occurs when a large amount of toxic substances enter the human body in a short period of time.
(2) Exposure to industrial toxins in a toxic state, but without symptoms or physical symptoms of poisoning, with the amount of toxins (or metabolites) in urine or other biological materials exceeding the upper limit of normal values; Or positive results in displacement tests (such as lead and mercury displacement). This state is called toxic state or toxin absorption state, such as lead absorption.
(3) Other occupational cases such as beryllium can cause beryllium lung disease; Fluoride can cause skeletal fluorosis; Chloroethylene can cause limb osteolysis; Tar pitch can cause skin darkening and other conditions.
(4) Certain chemical toxins that can cause mutations, carcinogenesis, and teratogenicity can cause variations in the body's genetic material. Chemical substances with mutagenic effects are called chemical mutagens. Some chemical toxins can cause cancer, and chemicals that can cause cancer in humans or animals are called carcinogens. Some chemical toxins have toxic effects on embryos and can cause deformities. These chemicals are called teratogens.
(5) The impact on reproductive function of industrial toxins can have effects on female workers' menstrual cycle, pregnancy, lactation and other reproductive functions, which are not only harmful to women themselves, but also can affect the next generation. Female workers who come into contact with benzene and its homologues, gasoline, carbon disulfide, and trinitrotoluene are prone to developing premenstrual syndrome; Female workers exposed to lead, mercury, and trichloroethylene are prone to experiencing oligomenorrhea syndrome. Chemical mutagens can cause mutations in germ cells, leading to fetal abnormalities, especially during the first three months of pregnancy when embryos are highly sensitive to chemical toxins. During the process of embryonic development, certain chemical toxins can cause delayed fetal production, deformities in the organs or systems of the embryo, and the death or absorption of fertilized eggs. Both organic mercury and polychlorinated biphenyls have teratogenic effects. Male workers exposed to carbon disulfide may experience a decrease in sperm count, which can affect fertility; Lead and dibromochloropropane also have an impact on male fertility. Lead, mercury, arsenic, carbon disulfide, and other substances can enter the body of lactating infants through breast milk, affecting the health of the next generation.
