Various enterprises of JSC “Samarkandkimyo”, which produce a wide variety of ammonium and nitrate saltpeter, are sources of nitrogen, phosphorus, potassium, and ammonium ecotoxicants in the republic. Phosphate manufacture in Uzbekistan, such as superphosphates, hexachlorobutadiene, tri- and tetrachlorethylene, and others, are sources of nitrogen-phosphorus-potassium and ammonium toxicants. JSC “Samarkandkimyo” (petrochemical complex in the city’s industrial zone) is one of Uzbekistan’s largest enterprises for the production of nitrogen and phosphorus-containing fertilizers of the 2.4-D group, which are among the most effective and widely used, as well as the country’s main supplier of nitrogen-phosphorus-potassium and ammonium xenobiotics.

Dioxins, which are considered by many researchers as worldwide superecotoxicants with a broad spectrum of biological activity in extremely low levels on all living things, are formed in tandem with the production of nitrogen-phosphorus nitrate. Dioxins are very harmful for people since they are stable in the environment due to accumulation and have a large potential for entering the body. The personnel of the enterprise (part of JSC “Samarkandkimyo”) which manufactures ammonium and nitrate saltpeter (ammophos, nitrophos) were examined. The age of workers in production ranged from 20 to 55 years, of whom 53 were men, 48 women; work experience in these industries ranged from 1 to 35 years.

As a control group, a voluntary group of 100 patients, comparable in age and sex to the main group, who sought dental care at the Samarkand Regional Dental Clinic but did not come into contact with dangerous substances such as nitrogen-phosphorus-potassium and ammonium compounds, were studied.
