The Material Flow Cost Accounting (MFCA) is a management tool that can help the organizations from any industry to better understand what are the environmental and financial potential consequences of their practices using materials and energy. Applying such methodology, that aims and quantifies the flows and stocks of materials within organization in physical units to which are associated the related costs, can give to managers the information needed to generate simultaneously the reduction of the environmental impacts and financial benefits. This poster presents the methodology of continuous improvement of environmental performance and the results of its application in an organization, providing cleaning products, with implemented environmental management system.

The aim of the paper is to create new biomaterials- biodegradable protein (Collagen)- based ”CoreShell/Hollow” structural nano- SiO2 composite and to find applications for drug delivery system. These surfactant based composites can used for biomedical field, for ensure health and improvement of life quality. Biocompatibility between drugs and substrates (membranes, matrices, polymer films, hydrogels, creams, capsules, pearls, powders, nanoparticles) is a very important issue for the optimal prescription of different treatments for the human body and maintaining health. It was obtained biomaterials by immobilizing drugs on various polymeric substrates, establishing the optimal conditioning formula, both in the preparation phase and in the adsorption phase of active components on the substrate. These are structured nanoparticles which contain a core from one material (or hollow) and a protective shell from another material, with sizes ranging between: 20 and 200 nm. The basic composition for both the core and the shell can be changed, providing a wide range of properties and applications (e.g. nanosensors, dyes). “Core-Shell/Hollow” structures are synthesized in two stages: the core is synthesized through conventional polymerization in emulsion and then it is incubated with a secondary emission, containing monomers and initiators, synthesizing the shell. The droplet fusion process and monomer migration determine core occurrence in the second emulsion, on which shells are formed by polymerization. Protein/”Core-Shell/Hollow” and SiO2 nanoparticle structures, with applications in controlled drug release systems are a new trend in biomedicine and a challenge for experts in the field.

A liquid chromatographictandem mass spectrometry method (LCMS/MS) for the simultaneous identification and quantification of seven organophosphate insecticides (fenthion, disulfoton, azinphosethyl, azinphosmethyl, dimethoate, omethoate, demetonsmethyl) and one herbicide (bentazon) used in agriculture was developed. A complet set of LC, electrospay ionization (ESI) and MS acquisition parameters was established for determination of analytes; these parameters were used in the detection of pesticides in the positive and negative mode.The pesticides were extracted from water by solid phase extraction (SPE) using conditioning and elution with methanol and finally the analytes were separated and detected by LCMS/ MS, under multiple reactions monitoring mode (MRM). The linearity of the calibration curve was good in the concentration range 0.4 ng/mL to 224 ng/mL, and the limits of detection (LOD) ranged from 0.1 ng/L to 4.5 ng/L. The mean recovery ranged from 70.9% to 108%. The metod was applied in the analysis of the surface water of Danube Delta in 11 sampling points. The insecticides concentrations were situated below the LOD. Only bentazon herbicide was determined in concentrations ranging from 0.37 to 1.4 ng/L.

Even though egg is considered „nature’s perfect food”, especially due to its high protein concentration of great biological value (essential amino acids profile) and high digestibility of nutrients contained, fear of cholesterol represents a barrier to the evolution of the average individual consumption. As a result there is an effervescence among researchers to obtain eggs with a reduced cholesterol content compared to standard egg. Among the ways used to lower egg cholesterol, dietary supplementation of laying hens with polyunsaturated fatty acids (PUFA) is included. In this context for seven weeks a study on 120 hens Lohmann Brown (55 weeks of age) was performed to determine whether the presence of camelina and flaxseed meals (PUFA omega 3 enriched forages), determine an quality improvement of the egg. The birds were divided into 3 groups (C, E1, E2), housed in enriched cages. The basic structure of the diet was the same for all three groups. The difference between experimental diets and control diet was given by the inclusion of camelina and flaxseed meals in E1 diet (2% camelina meal +5% flaxseed meal) or E2 diet (5% flaxseed meal), respectively. Every three weeks, a number of 18 eggs/group were collected randomized, of which 6 samples/group (3 eggs/sample) were formed to determine the quality of eggs (physical parameters, cholesterol and fatty acids content). The results showed that in the diets, PUFA ratio: omega 6/omega-3 was 22.83 in C group, 4.785 in E1 group and 5.385 in E2 group. The concentration of α-linolenic acid (C18:3n3) in diets was: 1.35% fat (C), 8.18% fat (E1), 7.23% fat (E2). Yolk and whites weight did not differentiate between groups. In contrast, in group C, eggshell weight (0.41±0.01mm) was significantly (P≤0.05) higher than in E2 (0.349±0.026 mm). There were no significant differences between groups in terms of yolk color, Haugh unit and the eggshell breaking strength. The content of α-linolenic acid (C18:3n3) in egg yolk was 0.403g/100g fat in C group, significantly (P≤0.05) lower than E1 (1.82g/100g fat) and E2 (1.87g/100g fat). Omega 6/omega 3 PUFA ratio at 100g of fat in the yolk was: 16.851 to C group significantly (P≤0.05) higher than 5.44 to E1 and 5.29 E2 groups, respectively. Cholesterol content (g/whole egg) registered in C (0.266±0.025) was significantly (P≤0.05) higher than E1 (0.224±0.028 mg/egg) and E2 (0.229±0.01928 mg/egg). Analysis of collected litter during the experiment showed that heavy metals concentration (Cu, Zn) did not differentiate between the 3 groups, therefore there is no danger in case of storing or their practical application as organic fertilizer. We appreciate that using flaxseed meal alone (E2 diet) or together with camelina meal (E1 diet) an egg, with functional food properties, can be obtained.

Evaluation of environmental performance is used by the top management to make informed decisions about the efficiency and effectiveness of operation environmental management system and to prioritize the environmental line from one stage to another. Selection and use in environmental analysis the relevant indicators for organization is always the key of success for a fast and effective management reviews. This paper aims to provide a guide for reporting environmental performance for organizations in the food industry, specifically in the brewing and beverage industries, easy to use by the top management in the periodic performed analyses. The guide is composed by tables with sets of general indicators / generic and specific: - energy efficiency, - efficient use of raw materials and materials, - use of water resources, - minimizing waste, - minimizing emissions (discharges to air, water, soil), - maintaining biodiversity. Sets of indicators proposed, of a general/generic nature, relevant to the food industry are understandable thereby facilitating assessment of environmental performance in any organization. From these indicators of general / generic nature can be derived specific indicators for various industries to enable organizations to improve the identification and reporting their environmental performance to all stakeholders.

The food industry by-products come in large amounts worldwide, reaching up to 50% of the total waste produced in some countries. This is both an economic, social and environmental problem. On the other hand, the compound feeds are the main cost factor for farmers, reaching up to 80% of the production cost for poultry. Any proper use of low input feeds improves the poultry production performance, but it remains to evaluate the environmental impact of these by-products. The paper presents the environmental and animal health impact of 22 vegetal by-products in terms of their heavy metals load. The environmental impact of these industrial by-products was considered in the circumstance of their storage on the soil. There were determined the concentration of cadmium, cobalt, total chromium, copper, nickel, lead and zinc. The evaluation of potential risky by-products for animal health was done by comparison of the analytical results with the regulations regarding the quality and salubrity for feeds and feed additives. The results show that seven by-products samples exceed the upper admitted levels of heavy metals concentration. In the poppy meal exceeded Cd concentration (1.88 mg Cd / kg vs legally allowed value of 1.0 mg/ kg) and Cu concentration (60.0 mg Cu / kg vs legally allowed value of 35.0 mg / kg). Also, the sesame meal exceeded the Cu concentration (59.7 mg Cu / kg vs legally allowed value of 35.0 mg/ kg). In the germ meal wheat exceeded the Zn concentration (273 mg Zn / kg vs legally allowed value of 250 mg/ kg). In other 4 samples (poppy meal, sesame meal, sunflower meals, nuts meal) exceeded the Cu concentration. The following analyzed by-products showed to be safe for animal health and for the environment: soybean meal, meal of mustard, buckthorn meal, flax meal, apple mash, full fat mixed sites, marc and leftover vegetables.

Many recent studies in the field of wastewater treatment and environmental protection have focused their attention on the possibility of obtaining aerobic granular sludge in order to develop new innovative wastewater treatment technologies. Compared to conventional activated sludge wastewater treatment plants, aerobic granular technology represent a novel alternative offering numerous advantages such as high biomass retention, good settling ability and simultaneous removal of organic load and nutrients. The main focus of research was to evaluate granules formation and evolution of treatment performances during startup and steady state conditions. Two lab scale sequencing batch bioreactors were used in the experiment: one of the bioreactors (D) was inoculated with conventional activated sludge while the other one (GM) was inoculated with crushed aerobic granular sludge. Both bioreactors were fed with dairy industry wastewater with high organic and nutrients load (CODCr = 1723 – 3550 mg O2/L, BOD5 = 492 – 1806 mgO2/L; NH4+= 64.6 - 114 mg/L, P tot = 5.04 – 21.5 mg/L) and underwent the same operational cycle: anaerobic feeding (45min), aerobic reaction (11 h), settling (5min.) and effluent withdrawal (10 min). The first granular structures were observed after 5 days (10 treatment cycles) with a diameter of 67 to 556 μm in D bioreactor and with 392 to 1200 μm in GM bioreactor. After 25 days the granules in D bioreactor increased significantly reaching diameters between 513 μm and 1276 μm. By the end of the experiment the granules reached 2 mm in diameter. The granules in GM bioreactor increased to 764-1482 μm and reached up to 4 mm in diameter by the end of the experiment. Treatment performances increased along with the growth of granules size.

This paper presents the results of an indoor air quality monitoring study conducted in an office building located on the outskirts of Bucharest, in an area characterized by low traffic and no major industrial pollution sources, during the summer of 2013, from 14thof June to 3rdof July. The aim was to determine the concentration of particulate matter dimensional fractions PM2.5 (particulate nominal diameter less than 2.5μm), PM10 (particulate nominal diameter less than 10μm), Total Suspended Particles (TSP), the PM2.5 and PM10 percent from TSP, metals and also the watersoluble anions present in the particulate matter in indoor air. The concentration of particulate matter varies widely from a minimum of 11.93μg/m3 for PM2.5 in weekend up to a maximum of 86.75μg/m3 in a working day with intense activity. The PM2.5 average concentration for the period was 42.64±28.28μg/m3; for PM10 it was determined a period average of 44.09±28.29μg/m3 and 46.44±30.41μg/m3 for TSP. The particulate matter are composed mostly of fine particles; fo PM10 contains a 96% of PM2.5 and total suspended particulates are form from 91% of PM2.5. Analysis by ICPEOS technique for the acid mineralization of the particulate matter retained on the filters lead to the identification of 15 metals: K, Ca, Fe, Al, Na, Mg, Pb, Zn, Ni, Ba, Cu, Ti, Mn, As, Cr. The metal content in the three dimensional fractions is different, indicating the probability existence of an indoor source for particulate matter with metals. Regarding the content of watersoluble anion in the three dimensional fractions, were identified following ions: NO3 > SO4 2>Cl >F >PO4 3>NO2. Pearson Correlation Analysis indicated a high correlation between all the dimensional particulate fractions and also between metals and anions present in particulate matter. As so, the correlation coefficients for metals have values of R=0.96 for PM2.5/PM10; R=0.93 and R=0.88 for TSP/PM10 for PM2.5/TSP. The high correlations were maybe obtained due to the composition of the PM10 and the TSP, both consisting in PM2.5 particulates in percentage of over 90%.
