    Noise pollution measurements of Giresun city center at the black sea border
    (2007) Kalipci E.; Dursun Ş.; Ozdemir C.
    Recently, the noisy problem is increasing parallel to the improvement of the technology, which arises in the developed countries and makes the life difficult. It is recently one of crucial environmental problem that it is a sort of pollution, still least known and least struggled in our country. However, the investigations carried out on noise pollution have brought up that the matter is a problem of public health gaining importance increasingly. The aim of this study was noisy measurements, both to determine the noisy level of the Giresun City and to attract attention the noisy pollutions exposed in the centre centre. Based on the measurements of the noise level in the Giresun City, the charts were prepared in such way that they showed the noisy level of the streets, the districts, and the industries and it has been found that limit values were exceeded in the most spots.

    The removal of lead and nickel ions from the water with Verbascum cheiranthifolium l. material [Sudan kurşun ve nikel iyonlarinin verbascum cheiranthifolium l. materyali ile giderimi]
    (Gazi Universitesi Muhendislik-Mimarlik, 2014) Dursun Ş.; Köysüren H.N.
    In this research, removal Pb(II) and Ni(II) ions from aqueous solutions by modified mullein (Verbascum cheiranthifolium BOISS. var. cheiranthifolium) plant material was investigated. Effects of modification method on the adsorption capacity improvement for removal of these heavy metals ions have been investigated. Structures of modified mullein plant materials before and after modifications process were examined by the FTIR and SEM analyses. Modification processes were performed using HC1 acid solutions. The investigations of kinetic, isotherm and thermodynamic parameters were also studied for HC1 modified mullein plant material. The regeneration processes were studied for the determination of modified mullein plant material's reusability after the adsorption processes. Additional costs for applied modification processes were calculated and compared with the other classical methods. The chemical oxygen demand residues in treated water by modified mullein plant material comparing raw materials were decreased from 910-1430 mg/L to 10-90 mg/L with the modification processes. The removal efficiencies changed with heavy metal concentration in water sample and increased about 70% for modified mullein plant material. Heavy metal adsorption capacities were found maximum about 90 mg/g according to type of adsorbent and modification process. As a result, it was revealed that adsorption capacities and costs efficiency of adsorbent were compatible with conventional adsorbents.

    Road traffic noise pollution measurements of trabzon city centre at black sea border
    (2007) Kalipci E.; Dursun Ş.; Ozdemir C.
    Recently, the effect of noise pollution appeared due to noise increasing from highway transportation, especially, the great majorities of the people living in city centers. Identifying the noise levels have gained great importance in terms of planning of the cities, regions, industries and our being informed how degree the noisy pollution have influenced our daily life. Development plans performed in our country have been carried out without taking into consideration the factor of noise pollution. One of the biggest reasons of it has also resulted from not being available data, adequate and healthy. Therefore, with this study carried out, it has been attempted to determine how degree the people have been influenced from the noise. On the main streets and arteries in Centrum of Trabzon, making noise measurement for totally 100 spots, some charts showing the noisy levels in the city were prepared. It has been found that, on all spots, where the noise measurements were performed, limit values were exceeded, and the noisy levels had reached the size threatening the human health. In this study, it has been suggested that the results obtained were harmful regarding to human health and the measures to be taken were briefly indicated.
