Subject and purpose of work: The aim of this work is to present the possibilities of cultivating varieties of industrial hemp which are registered in Poland in areas of high nature value. Materials and methods: This work is a type of overview; it describes characteristic features of areas of high nature value. It also presents specific biological properties, cultivation and agrotechnical requirements, as well as the versatility of industrial hemp usage. Results: This study demonstrated considerable importance of industrial hemp in developing areas of high nature value, in accordance with the idea of sustainable development. Conclusions: Due to the specific biological properties of industrial hemp, its low cultivation and agrotechnical requirements and lack of the need to use pesticides, industrial hemp can be successfully grown in areas of high nature value.
This study was carried out in a car factory at workplaces in various states of activity. The measurements of substances enlisted as carcinogenic found at workplaces in some departments in 1995-1997 was carried out as well as the evaluation of microclimatic conditions and the evaluation of sick absenteism in the whole factory. Analysis of results revealed that microclimates in the rooms in the studied departments did not exceed permissible hygienic standards, except for some workplaces in the suspension springs department and the tool room. The analysis of exposure to particular/specific factors in 1995-1997 enlisted among carcinogenic substances did not reveal any toxicological health hazard. Sick absenteism in the whole factory and studied departments in the analyzed period varied. The prevailing group of diseases were diseases of the respiratory system. Morbidity from cancer was low.
The aim of the study was to evaluate the prevalence of hyperuricaemia and gout in the population of the Tychy urban agglomeration that is only moderately exposed to ecotoxins. Energy expenditure during professional work and dietary habits were taken into account. The study was carried out in 1957 subjects, including 1391 men and 566 women, divided into 5 groups differing in the physical activity connected with their work. In all subjects the serum uric acid level was determined, what enabled isolating cases with hyperuricaemia and gout. The evaluation of dietary habits was performed. The prevalence of hyperuricaemia was found to be 37.9% in the whole population studied, and that of gout was 2.4% in men and 2.5% in women. The occupational physical activity decreased the serum uric acid level. High-calorie diet was a risk factor for hyperuricaemia.
Subject and purpose of work: The raw materials which are the purpose of the current hemp cultivation (<0.2% THC) are fibre, seeds and shives. This study describes the characteristics the raw materials obtained from the industrial hemp and described in detail the possibilities of their applications in pulp and paper, textile, pharmaceutical, construction and food industries. Analysis of the issues: Hemp straw consists of a porous ligneous core, which may be cut into smaller pieces, called hemp shives and of the fibre around the core. Hemp cellulose is used to produce paper pulp or plastics. In the construction sector, hemp fibre is used to produce, among other things, thermal insulation materials. Hemp shives is used as a filler for a composite based on lime binder, which is used as a wall material with good hygrothermal conditions confirmed by proprietary research. Hemp seeds are used for the production of cooking oil. Hempseed oil is also used in the pharmaceutical industry, e.g. to produce skin creams. Conclusions: Raw materials obtained from industrial hemp have a variety of applications. Currently, new directions in hemp application are being sought and tested, like for example hemp lime composite and bio-composites. The positive environmental impact resulting from the cultivation of hemp should be the main reason for simplifying the procedures for the commencement of its cultivation in many countries, e.g. in Poland.
