Introduction. Work in pharmaceutical-chemical industry is characterized by exposure to numerous hazards, both physical (microclimate, illumination, noise) and chemical (organic solvents). Organic solvents can cause damage to many organic systems and have carcinogenic, teratogenic and mutagenic effects. Objective. The aim of this study was to analyze patterns of chronic morbidity of workers employed in pharmaceuticalchemical industry during 2002. Method. The study was conducted in the pharmaceutical- chemical industry "Zdravlje" Leskovac in 2002. A total of 143 workers in workplaces with special working conditions - exposed to chemical hazards as well as 40 workers from control group took part in the study. The physical examinations of the participants were performed at the Department of Occupational Health in Health Center, Leskovac. Results. Heart diseases were the most frequent both among exposed workers (17.8%) and in control group (33.3%). Respiratory diseases were at the second place (16.9% in the exposed group, and 7.4% in control group). Arterial hypertension was diagnosed in 14.7% workers occupationally exposed to hazards, and in 12.5% workers from control group (p>0.05). Chronic bronchitis was diagnosed in 17.5% of the exposed workers and in only 5.0% of controls (p>0.05). The highest prevalence of diseases in both groups was observed among workers aged 40-49 years, with 20-29 years of exposure working time. 73.4% of the exposed workers and 85% of control workers were capable of work (p>0.05). Conclusion. Workers occupationally exposed to hazards in pharmaceutical-chemical industry have higher prevalence of various diseases compared to non-exposed workers, which can be the result of work, working conditions and work activity. Preventive measures should be directed towards the decrease of occupational hazards and unfavorable working conditions and increase of work protection. Regular physical examinations of workers are of prime importance for the prevention of occupational morbidity, traumatism and invalidity. .

Operational Program

A measure “Establishing Environment Conducive to Enterprises Development” was one ofstrategic goals of the Sectoral Operational Program “Improvement of competitiveness of theeconomy, 2004–-2006”. This measure will be compatible with a development of the enterprisesand entrepreneurship in technology and industrial parks.Despite industrial and technology parks have similar goals, these facilities are different. Eachpark has its own unique nature because of its regional, cultural and economic conditions as wellas available growth potential.The initial profile of The P³ock Industrial and Technological Park –created in July 2004//shareholders: PKN ORLEN /50%/ and City of Płock /50%/ – was defined by the basic operationof PKN ORLEN and will benefit from financial and technological potential of this company.This program will activate the local R&B potential connected with the chemical industry andrelated fields, such as: environmental protection, waste treatment and recycling, logistics as wellas financial and banking services, IT, and telecommunications.

The Individual

This article reviews the use of fluids under supercritical conditions in processes related to the modern and innovative polymer industry. The most important processes using supercritical fluids are: extraction, particle formation, micronization, encapsulation, impregnation, polymerization and foaming. This review article briefly describes and characterizes the individual processes, with a focus on extraction, micronization, particle formation and encapsulation. The methods mentioned focus on modifications in the scope of conducting processes in a more ecological manner and showing higher quality efficiency. Nowadays, due to the growing trend of ecological solutions in the chemical industry, we see more and more advanced technological solutions. Less toxic fluids under supercritical conditions can be used as an ecological alternative to organic solvents widely used in the polymer industry. The use of supercritical conditions to conduct these processes creates new opportunities for obtaining materials and products with specialized applications, in particular in the medical, pharmacological, cosmetic and food industries, based on substances of natural sources. The considerations contained in this article are intended to increase the awareness of the need to change the existing techniques. In particular, the importance of using supercritical fluids in more industrial methods and for the development of already known processes, as well as creating new solutions with their use, should be emphasized.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.
