Pulp and paper enterprises are of great importance for sustainable economic and environmental development of certain regions and the economy of Ukraine. Man uses many natural resources during the lifetime, creating a burden on nature. As the world's population increases, this load increases, leading to a shortage of resources and deterioration in the environment. The main activity of Kokhavynska Paper Mill PJSC is the production of sanitary products for the domestic market and export. Rational use of secondary raw materials helps to cut the use of forest resources and reduce the amount of waste paper utilized in landfills. 15291.76 t of pollutants from the sources of the enterprise emissions enter the air each year. A total of 9 standardized and 3 non-standardized substances (greenhouse gases) are released into the atmosphere, namely nitrogen oxides, carbon monoxide, nitrogen (1) oxide (N 2 O) (greenhouse gas), carbon dioxide (greenhouse gas), methane (greenhouse gas), iron and its compounds, manganese and its compounds, hexavalent chromium (expressed in terms of chromium trioxide), gaseous fluorides, hydrogen sulfide, saturated hydrocarbons C12- C19. There is no excess of the established maximum concentration limits at all emission sources at this enterprise. To assess the impact of the enterprise on soils, the content of heavy metals Zn, Cr (VI), Co, Cu, Pb, Mn, and Fe at the border of the sanitary protection zone of the enterprise was determined and the maximum multi plicity of the excess of MPC of heavy metals was calculated. The content of heavy metals in the selected soil samples was determined using a spectrophotometer atomic absorption C-115-M1. Evaluation of soils for heavy metals showed that the soils at the border of the sanitary protection zone of the enterprise are contaminated with heavy metals. The maximum multiplicity of the excess of the MPC of heavy metals in the soil is 1.04 times for lead; 0.43 times for zinc; 0.37 times for chromium; 0.93 times for copper; 1.85 times for manganese; 0.35 times for cobalt. Maximum concentrations of heavy metals exceed their background content: 1.6 times for lead; 1.8 times for zinc; 1.16 times for chromium; 0.77 times for copper; 3.9 times for manganese; 9.7 times for iron; 1.2 times for cobalt.

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.

Domiati cheese is the most popular brand of cheese ripened in brine in the Middle East in terms of consumed quantities. This study was performed to investigate the impact of the microbiological quality of the used raw materials, the applied traditional processing techniques and ripening period on the quality and safety of the produced cheese. Three hundred random composite samples were collected from three factories at Fayoum Governorate, Egypt. Collected samples represent twenty-five each of: raw milk, table salt, calf rennet, microbial rennet, water, environmental air, whey, fresh cheese, ripened cheese & swabs from: worker hands; cheese molds and utensils; tanks. All samples were examined microbiologically for Standard Plate Count (SPC), coliforms count, Staphylococcus aureus (S. aureus) count, total yeast & mould count, presence of E. coli, Salmonellae and Listeria monocytogenes (L. monocytogenes). The mean value of SPC, coliforms, S. aureus and total yeast & mould counts ranged from (79×102 CFU/m3 for air to 13×108 CFU/g for fresh cheese), (7×102 MPN/ cm2 for tank swabs to 80×106 MPN/ml for raw milk), (9×102 CFU/g for salt to 69×106 CFU/g for fresh cheese) and (2×102 CFU/cm2 for hand swabs to 60×104 CFU/g for fresh cheese), respectively. Whereas, E. coli, Salmonella and L. monocytogenes failed to be detected in all examined samples. There were significant differences in all determined microbiological parameters (p ≤0.05) between fresh and ripened cheese which may be attributed to different adverse conditions such as water activity, pH, salt content and temperature carried out to improve the quality of the product.

The City

The impact of the urban effluents of Mytilene (Lesvos island, Greece) on the receiving coastal marine environment, was evaluated by studying the quality of the city effluents (BOD5, COD, SS, heavy metals) and the marine sediments (grain size, organic matter, heavy metals). It was found that the urban effluents of Mytilene contain high organic matter and suspended particle load because of septage discharge into the sewerage network. Furthermore, although the city does not host important industrial activity, its effluents contain appreciable metal load, which is mainly associated with the particulate phase. The city effluents are discharged into the coastal marine environment and their colloidal and particulate matter after flocculation settles to the bottom, where is incorporated into the sediments. Over the years, the accumulation of organic matter and metals into the harbour mud has created a non-point pollution source in the relatively non-polluted coastal marine environment of the island. Copper and Zn were the metals which presented the higher enrichment in the sediments of the inner harbour of Mytilene.

Educational Diversity

ABSTRACT Greenhouse gas (GHG) assurance is increasingly used by companies as a means to increase stakeholder confidence in the quality of externally reported carbon emissions. The multidisciplinary nature of these engagements means that assurance is performed primarily by multidisciplinary teams. Prior research suggests the effectiveness of such teams could be affected by team composition and team processes. We employ a retrospective field study to examine the impact of educational diversity and team member elaboration on multidisciplinary GHG assurance team effectiveness. Results show that team processes such as sufficiency of elaboration on different team member perspectives significantly increases the perceived effectiveness of the teams. While educational diversity is not found to directly improve perceived team effectiveness, it is found to have a positive effect through increasing perceived sufficiency of elaboration. These findings have important implications for standard setters and audit firms undertaking GHG assurance engagements.
