Opis:
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.

Opis:
Agrophysics is a science dealing with physical properties and processes affecting plant production. The main topics of agrophysical investigations are mass ( water, air, plant nutrients) and energy (light, heat) exchange in the soil-plant-atmosphere continuum and way their regulation to reach biomass of high quantity and quality. Agrophisical investigations can be presented in the form of a tree - parameter system of classification. the term "Agrophysics" similarly to "Agrochemistry" "Agrobiology" "Agromelioration""Agroclimatology" or "Agroecology" has been fully accepted as an agricultural specialization. Agrophysics research are developed by meny scientific institutes but only the Instituí of Agrophysics in Lublin (Poland) is the strongest unit for a complex investigations in the field of agrophysics.AC The Institute of Agrophysics (IA PAN) is one of the institutes of the Polish Academy of Sciences, It was founded by Professor Bohdan Dobrzański in 1968 in Lublin who was the first and long-term director of the Institute (till 1980). The staff of the Institute consists of 100 workers including 68 scientific representing various specializations: physics, physicochemistry, soil science, agricultural engineering, mechanics, mathematics, electronics, geography and biology. These scientists have ery high qualifications achieved during long trainings in domestic and foreign centres. They were employed as postgraduate students and got their scientific degree on agrophysics. The Institute uses it's own building covering a surface of about 5 000 m2 situated in Lublin-Felin. The scientific structure of the Institute consists of six departments: 1. Hydrolherrnophysics of Soil Hnvironment and Agricultural Materials. 2. Aeration and Gas Exchange of Soil Environment and Agricultural Materials. 3. Mechanics of Agricultural Materials. 4. Physicochemistry of Agricultural Materials. 5. Agrophysical Bases of Soil Environment Management. 6. Physical Bases of the Evaluation and Improvement of Plant Materials, The Institute is a coordinator of agrophysical investigations in Poland and cooperates with meny scientific institutions over the world. The agrophysicial investigations carried out by the Institute and under its coordination allow us to deepen our fundamental knowledge about the physical and physicochemical properties and processes concerning agricultural materials. They also have introduced new elements to environmental protection which are significant to the economy. The results from these investigations may be used to: decrease soil physical degradation caused by erosion, soil crusting, sealing, compaction and structure destruction; increase the efficiency of water and fertilizer use; improve the technology of harvesting, storing and processing of plant materials to decrease quantitative ad qualitative losses of these materials; improve plant breading through formulation of physical properties of plants. The development of a theoretical basis in the field of agrophysics is of great importance for many agricultural specialization, e.g., soil science, soil technology, land reclamation, agricultural engineering, agroclimatology, agrochemistry, plant breeding and plant technology.
