ABSTRACT
This study intends to research using absorbent (elcosorb) as an alternative to existing and applied treatment technologies used to remove oil from the waste waters of milk industry origin which contain intensive oil concentration and to find out applicability of this absorbent with regard to the efficiency and profit-cost. During work, absorbent has been applied in the full-mixing batch reactor and packed bed reactor and it has been found out that removal efficiency of absorbent for the oil is higher on the packed bed reactor. Absorption capacities of absorbent (elcosorb), wood shavings and animal bagasse were compared using same experimental system and found the oil absorption capacity of elcosorb was better than the others. As a result it seems to be with regard to efficiency that absorbent is applied by using packed bed reactors so as to be an alternative to today’s applied oil removal technologies. However that absorbent in completely imported material as of its origin and loosing is quality after single usage makes impossible to recover it.

ABSTRACT
In this study, folk medicine plants [achillea millefolium l., a. nobilis l., (compositae); ecballium elaterium a. rich., (cucurbitaceae); melissa officinalis l., (labiatae); alcea pallida (willd.) waldst. & kit., (malvaceae); malva sylvestris l., (malvaceae); ammi visnaga (l.) lamb., (umbelliferae); origanum sipyleum l., (labiatae); papaver rhoeas l., (papaveraceae)] of gediz (Kütahya, Turkey) and it is sourroundings and traditional application of these plants were investigated. as a result of these works, 9 species belonging to 6 families used for 11 treatments were determined. four of them have been used for respirational diseases, 3 of them have been used for degistional diseases, 2 of them have been used in circulation, 2 of them has been used in diabetes, 1 of them has been used in diabetes, 1 of them has been used in malaria and 1 of them have been used as analgesic drugs.

ABSTRACT
In this study, Zn,Cu, Pb, Mn and Fe levels of lettuce (Lactuca sativa L. var. longifolia Lam.) watered with sewage water, the sewage water and soil samples in Hevsel gardens have been determined. Moreover, heavy metal levels of lettuce grown with water from an unpolluted stream, and of stream water and soil samples of this area have been determined. The results obtained show that the levels of Zn, Cu, Pb, Mn, and Fe are higher in lettuces grown in Hevsel gardens compared to that grown with stream water. Therefore, it has been shown that the accumulation of these metals in lettuce and soil due to sewage water occurs in large extend.

ABSTRACT
Mersin-Silifke shore-line has been an important setlement area since the antic ages. In this area, population has been increasing due to the migration of part of Turkey from Eastern and Southeastern people since 1950 s and the area has faced an unplanned urbaning and secondary housing settlements. Rapid and uncontrolled urbaning had important effects on environment in the area. In our country, Urban Development Legislations, have become very unsufficient for the protection of enviroment. Shore-lines and agricultural (lands) have been opened for settlements and this aplication has destroyed the ecological balance. In this study, the use of secondary (summer) houses and its environmental effects on urban development in Mersin-Silifke shore-line were investigated. As a result of this study, it is recommended that the ÇED process based on the principles of determination of environmental effects and taking necessary precautions would be useful for the rehabilitation of existing settlement regions, the development of new settlement units and the formation of urban development projects.

ABSTRACT
Global warming promises to be one of the most important environmental issues in the next millenium. Changes in global climate will likely affect the behavior and life histories of animals including insects. For many insects as temperature and humidity increase, developmental rates, speed of movement, and fecundity will be increased and these changes should also affect many other ecological processes. Changes in climate will change features of the environment and these will also indirectly alter the behavior of insects living in these habitats.
Keywords: Global warming, insect populations, greenhouse gases

ABSTRACT
Fluoride is an important original element for human health that must be monitored in the environment. There is a connection with low fluorides in drinking water supplies and dental caries where excessive fluorides produce unsightly fluorosis that increases with increasing fluoride concentration. In order to determine the fluoride concentration of tab waters in the province of Eskişehir, samples were taken from city center and 61 different rural points. A fluoride selective electrode was employed to determine the fluoride levels in samples. Optimal levels were calculated as 0,8-1,3 ppm depending on the Eskişehir’s annual mean daily maximum air temperature, 17,2º C. Fluoride levels in the tab waters were ranging from 0,02 ppm to 3,9 ppm. 6,5% of the samples were containing optimal levels, where 90,3% of them were containing lower and 3,2% of them were containing higher levels. The total research area population was 490808. The results showed that 3.7% of the research area population were supplied by tab water containing optimal fluoride levels and 96.2% were supplied with lower and 0.1% were with higher levels.
