Relation between corolla coloring of herbaceous plants of Central Europe with its ecological characteistics according to Landolt and Ellenberg (982 and 1164 species) was studied. Special attention was paid to the shades of antocyanin color. It was revealed that red-color species prefer at the average mare strongly acidic soils (mean pH=6), than blue–color ones (mean pH=7). Also the relation between corolla coloring and flowering season was registered.

The dose-response relationship might be very important for risk modeling and for study of individual sensitivities. In extremely low frequency - zero magnetic fields, (ELF ZMF), this relation is not known and a deterministic or stochastic effect is not established. Inside of ours Helmholtz Coil System, only the natural fluctuation remains active when the static component of geomagnetic field has been compensated. Due to increase areas of relaxed DNA from lymphocyte’ nucleus, the increasing of comet tail and score lesions has been observed, which are equivalent with a genotoxic exposure.

The development of urbanization and industrialization represent two main factors leading to impaired quality of water bodies, directly or indirectly subjected to the action of pollutants. This study has followed the aquatic plants ability to reduce the pollutants present in water bodies. Therefore, the effects of aquatic plants water hyacinth (Eichornia crassipes) and water lettuce (Pistia stratiotes) on indicators: pH, turbidity, Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Nitrogen (TN) and Total Phosphorus (TP) have been studied at a wastewater derived from a poultry farm for a period of 40 days and an indicator of efficiency versus time has been represented. The obtained results have revealed the plants efficiency on the analyzed indicators, being emphasized that each group behaved differently. Due to the accelerated growth rate, these plants are one of the renewable energy resources of the future.

CONCRETE PRODUCTION WITH RECYCLED MATERIALS IN THE SUSTAINABLE DEVELOPMENT CONTEXT

The waste coming from demolition and construction can provide a source of recyclable materials, useable in the construction industry. In terms of environmental impact, the waste recycling and reuse from construction and demolition activities, reduce the occupied authorized landfills area. Also, by recycling and reuse, it is achieved an economy of non-renewable natural resources. From the economic point of view, the use of recycled materials in place of the natural resources, that reach extremely high costs, it becomes, from one year to another, a solution increasingly more advantageous. This paper presents some opportunities to recycling various waste (glass, polypropylene, filler, ceramic blocks) by using them in the concrete production. The experimental researches have revealed the opportunity to reconsider the four waste studied types, by introducing them as raw materials in the concrete preparation. Moreover, there is the possibility to obtain some types of concrete with special characteristics. Therefore, we can say that the waste recycling and reusing, and their revaluation as raw materials for the concrete production, is a technology which meets the sustainable development criteria.

INCREASING THE RESILIENCE OF ECONOMIC AGENTS BY IMPLEMENTING THE INTERVENTION AND RESCUE ACTIVITY
CRESTETEA PUTERII AGENTILOR ECONOMICI PRIN IMPLEMENTAREA ACTIVITATII DE INTERVENTIE SI SALVARE

Emergency management is a complex task, involving precise coordination of numerous activities and people, as well as fast decision-making in environments where critical, vital information, might often be missing. Despite all technical and technological progress, most industries record accidents with human casualties and property damage. For this reason the presence of special intervention – rescue teams at economic units is critical, because they can ensure a quick and efficient response to confine/eliminate damages that generate toxic or chemically aggressive environments and rescue personnel caught by surprise by such events. Research conducted so far found that in case of an explosion/fire type event, its first phase management by the economic operator is difficult, because economic units do not dispose of a structure capable of providing a urgent and effective response to such situations. In this circumstance, this paper aims on one hand to highlight, with the help of a case study, the serious consequences that may occur if the response time is delayed, and on the other hand to establish a series of activities (theoretical/practical, endowment, intervention procedures, etc.) that must be covered by economic operators to increase resilience to emergencies in hazardous environments.

RESEARCH ON THE POTENTIALITY OF USING AERIAL VEHICLES FOR MONITORING THE ENVIRONMENT AGENT - AIR
CERCETARI ASUPRA POTENTIALULUI UTILIZARII DRONELOR IN MONITORIZAREA AGENTULUI DE MEDIU AER

Unmanned aerial vehicles, "drones", are the most important invention the military field achieved in recent years. These are used in more and more fields such as agriculture, archeology, journalism, border control, inspection of high voltage power lines, small items transport, mapping, etc. This paper studies the possibility of using aerial vehicles in the field of environment protection for performing gas measurements at industrial exhaust sources, at different heights and for drawing isoconcentration maps. Also, they may be used in case of accidental releases of hazardous substances into air, resulting from a fire or explosion at industrial sites. Another possible use of aerial vehicles, under study to monitor air as an environmental factor is measuring industrial emissions over combustion plants. In this case, air currents created by drone and exhaust gas temperature will be taken into account. This method has a high degree of novelty as currently the standardized method for measuring emission of gases requires taking samples from the interior of industrial chimneys or pipes using heated probes. In practice, the situation where access to industrial chimneys is saddled or the chimney has no access holes is often met. In this respect, the use of an aerial vehicle, in case that research conducted will prove that it is possible and does not affect the quality of measurements, will be helpful to improve services, quick reaction in case of an event at a facility, for worker’s and environment security.

RISK ASSESSMENT OF POPULATION EXPOSURE TO NITRATES/NITRITES IN GROUNDWATER: A CASE STUDY APPROACH
EVALUAREA RISCULUI DE EXPUNERE A POPULATIEI LA NITRITII SI NITRATII DIN PANZA FREATICA - STUDIU DE CAZ

Drinking water is a necessary element for vital activity of population and the presence of nitrates/nitrites in excess may lead to severe health problems. Nitrates/nitrites can reach groundwater as a consequence of agricultural activity (including excess application of inorganic nitrogenous fertilizers and manures) and from oxidation of nitrogenous waste products in human and animal excreta. This study is focused on the evaluation of water quality within a rural area from Romania - i.e. Branesti - which is included on the authorities list of vulnerable areas to nitrate pollution. The aim of the paper was to establish the exposure of population in a more accurate way by the correlation between the content of pollutants in water, characteristics of the population group at risk (e.g. body weight) and the reference dose established in available toxicological research studies. The results indicated frequent concentrations exceeding the limit for nitrates imposed by current regulations concerning the water quality for human consumption, as well as some cases when other chemical and/or bacteriological indicators exceeded the maximum allowable limit. According to the European Drinking Water Directive (Directive 98/83/EC), a need for further monitoring emerged in this rural area together with the need of increasing the awareness of the population towards the health risk posed by nitrate/nitrite contamination.

HUMIDITY AND TEMPERATURE INFLUENCE ON ANTHOCYAN COLORING OF FLOWERING PLANTS COROLLA
UMIDITATEA SI TEMPERATURA INFLUENTEAZA COLORAREA CU ANTOCIAN A COROLEI PLANTELOR CU FLORI

Institute of Ecology and Geography, Academy of Sciences of Republic of Moldova, Chişinău, Republic of Moldova

The influence of the number of abiotic factors (soil acidity, soil fertility, soil humidity, temperature, climatic continentality, light availability and month of flowering) on anthocyan corolla coloring was studied on 272 species of flowering plants of C-layer. It was established, that the leading factors in color formation are temperature, humidity and soil fertility. For dicots plants the main factor is temperature.
