Zbadano 3418 próbek soli spożywczej, w tym 2440 próbek soli jodowanej. Odsetek próbek, w których stwierdzono właściwą zawartość jodku potasowego wynosił od 30% do 50% w zależności od producenta soli.

The purpose of the study was to assess the correctness of salt iodination and its distribution in Poland. The subject of the study was salt for human consumption iodinated or not, according to Polish norm PN-88/C-84081/02 „Sól (chlorek sodowy). Requirements. Salt samples were taken from retail shops or stores in 36 provinces. The study was carried out in the years 1992-1993 according to PN-80/C-84081.35 „Sól (chlorek sodowy) standard. Potassium iodide was determined by photo-colorimetry. The total number of studied salt samples was 3418, including 2440 samples of iodinated salt. The per cent of samples with proper content of potassium iodide was from 30% to 50% depending on the producer. The study demonstrated that in most cases the process of salt iodination is done incorrectly.

W 1994 r. zbadano 1586 próbek soli jodowanej. Odsetek próbek, w których stwierdzono zawartość jodku potasowego zgodną z wymaganiami wynosiła od 22% do 28%. W1995 r. zbadano odpowiednio 2129 próbek. Prawidłowe jodowanie wykazano w 57,4% próbek.

The consequences of iodine deficiency occurring still in Poland include serious health disorders in the population, such as psycho- somatic retardation, hypothyroidism, endemic goitre, even cretinism. Administration of iodized edible salt with daily diet is an effective method for prevention of iodine deficiency. The condition of success is the proper level of potassium iodide in this salt and adequate distribution of iodized salt in various regions of the country. Successful iodine prophylaxis should be based on iodination of edible salt in amounts of 30±10 mg of KJ/kg. The permission given in the period from February to May 1994 by the General Sanitary Inspector for the production and marketing of edible salt iodized in proportions of 30 ±10 mg KJ/kg opened the possibility of starting its production in salt mines. The purpose of the presently reported work was to assess, in cooperation with the Province Sanitary Epidemiological Stations, the adequacy of iodination of the Polish edible salt produced in the years 1994-1995. The study was carried out according to the Polish Standard „Salt (Sodium Chloride) /PN-80/C-84081.35. Potassium iodide determination by photocolorimetric method." In 1995 the number of edible salt samples analyzed was 2484, and this number included 2129 samples of iodized salt. Potassium iodide content agreeing with the above permission was found in 122 samples,that is in 57.4% of iodized salt samples. In 603 samples (28.3%) of iodized salt this content was below that given in the permissions. In 1994 this study was carried out taking 2172 samples of edible salt, including 1586 samples of iodized salt. The content of potassium iodide agreeing with the permissions (30 ±10 mg/kg) was found in 342 samples (28,1%), but 272 (22.4%) samples of iodized salt produced by salt mines contained lower amounts of potassium iodide than the amount indicated in the permissions,but still within the limits set down in the Polish Standard (20±5 mg/kg). The obtained results (57.4%) indicate an improvement of the process of salt iodination as compared with the results obtained in 1992 and 1993 (38.3%) and 1994 (28.1%). However, varying amounts of potassium iodide differing from the accepted values were found in salt declared as iodized.

Oceniono pobranie azotanów i azotynów z całodzienną racją pokarmową przez młodzież w wieku 14-19 lat. Przebadano 90 próbek diet. Ilość azotanów i azotynów pobierana przez młodzież wraz z posiłkami była zróżnicowana i w przypadku azotanów wahała się w granicach 13,1 mg NO3-/dzień/osobę do 408,9 mg NO3-/dzień/osobę. Zawartość azotynów w 87 próbkach diet była poniżej 0,2 mg NO2-/kg (granica wykrywalności metody), zaś największe pobranie azotynów przez młodzież wyniosło 3,2 mg NO2- /dzień/osobę. Porównując uzyskane wyniki z wartościami ADI, w przypadku 6 diet stwierdzono przekroczenie dopuszczalnego dziennego spożycia azotanów. Przekroczenie to wynosiło od 12% do 84%. W odniesieniu do azotynów nie zanotowano przekroczenia dopuszczalnego dziennego pobrania tych związków.

The aim of this study was evaluation of daily level intake of nitrates and nitrites with the daily diets of 14-19 year youths. Samples - daily food rations from boarding school canteens were been collected on the area of 8 provinces during 10 consecutive days from September to December 2001. A total of 90 daily food rations were analysed. Nitrates and nitrites content was determined by spectrophotometry after previous reduction of nitrates in cadmium column. The amount of nitrates supplied with the daily food rations ranged from 13,1 to 408,9 mg NO3-/day/person, while that of nitrites was from below 0,2 to 3,2 NO2-/day/person. In 6 daily food rations the level of nitrates exceed acceptable daily intakes (ADI) calculated for person of 60-kg weight. The detected amounts of nitrites not exceeded ADI in all evaluated daily diets.
