Hydrophobic Cellulose-Based Sorbents for Oil/Water Separation.

The need for sustainable, biodegradable materials to address environmental challenges, such as oil-water separation, is growing. Cellulose-based absorbents offer an eco-friendly alternative to synthetic materials. However, their hydrophobicity must be enhanced for efficient application.

Fire Properties of Paper Sheets Made of Cellulose Fibers Treated with Various Retardants.

This article presents the results of flame-retardancy tests conducted on cellulose sheets produced using a Rapid Köthen apparatus treated with retardants. The agents used were potassium carbonate (PC) KCO (concentrations of 20; 33.3; and 50% wt/wt), monoammonium phosphate (MAP) NHHPO (concentrations of 35% wt/wt), diammonium phosphate (DAP) (NH)HPO (concentrations of 42.

Predictors of short- and long-term sickness absence in female post office workers in Poland.

Background: The aim of this study was to highlight major predictors of the frequency of sickness absence in a group of workers directly involved in customer service.

Material And Methods: The study was carried out on a random sample of 229 women employed as assistants and clerks in post offices. The survey was based on the Subjective Work, Health Status and Life Style Characteristics Questionnaire, and sickness absence data for the years 2004-2006.

Predictors of lung cancer among former asbestos-exposed workers.

Objectives: Despite extensive literature concerning the risk of lung cancer incidence among asbestos workers there is still lack of data specifying the association between the level of exposure and the frequency of cancer occurrence. The aim of the analysis was to assess the influence of smoking and selected factors related to occupational exposure on the risk of the incidence of lung cancer among the workers who were exposed to asbestos dust in the past.

Material And Methods: The assessment was performed based on the case-control studies carried out within a cohort including 7,374 former workers of asbestos processing plants, examined over the years 2000-2013.

Asbestos related diseases among workers of asbestos processing plants in relation to type of production and asbestos use.

Background: Asbestos dust is one of the most dangerous pneumoconiotic and carcinogenic agents. The aim of this study was to assess the occurrence of asbestosis and pleural mesothelioma, depending on asbestos consumption and the type of manufactured products, among former asbestos workers in Poland.

Material And Methods: The study subjects included employees of 18 large state-owned asbestos processing enterprises operating in the Polish market in 1945-1998.
