A qualitative and quantitative evaluation of pollen concentration in the atmosphere of Izmir metropolitan area is presented. Investigations were undertaken from November 1998 to October 1999 using gravimetric method. The aeroplynological studies revealed that at lower level (1.60 m) pollen from 29 woody and 30 herbaceous taxa were determined, whereas at higher level (20 m) pollen from 26 woody and 24 herbaceous taxa were recorded. At lower level, dominating woody species were Pinus, Quercus, Oleaceae, Cupressaceae/Taxaceae; herbaceous species were Gramineae, Chenopodiaceae/ Amaranthaceae, Cruciferae and Plantago. At higher level, Pinus, Cupressaceae/Taxaceae, Gramineae, Chenopodiaceae/Amaranthaceae, Cruciferae and Plantago pollens were dominant. Morus, Oleaceae, Quercus, Chenopodiaceae/Amaranthaceae, Gramineae and Plantago showed highest concentration and their allergic degree was very high. Annual pollen calendar of the area is shown.

Cynodon dactylon, Nerium oleander and Pinus brutia a herb, a shrub and a tree; are very commonly met alongside the roads in the Mediterranean region of Turkey. Since roadside plants in this region are under a great pressure of traffic, an attempt was made to determine lead and cadmium accumulation in the species cited above. During summer, a peak traffic season in the Mediterranean above ground parts of C. dactylon, leaves of N. oleander and bark of P. brutia were collected between 0-5 m distance from 15 localities alongside the roads. These were subjected to an analysis in unwashed form. Results obtained revealed that Pb and Cd varied between 4.65-106.30 and 0.165-1.615 mg/g dry weight, respectively. The highest accumulation was in C. dactylon followed by leaves of N. oleander. Bark of P. brutia showed the lowest values.

Cynodon dactylon, Nerium oleander i Pinus brutia to, odpowiednio, trawa, krzew i drzewo; są one stosunkowo dobrze poznanymi roślinami przydrożnymi regionu wybrzeża M. Śródziemnego w Turcji. Ponieważ w tym regionie rośliny przydrożne znajdują się pod wpływem ruchu drogowego, dlatego oznaczano w nich ołów i kadm. Latem, w okresie wzmożonego ruchu na drogach, pobierano nadziemne części C. dactylon, liście N. oleander i korę P. brutia w odległości 0-5 m w 15 wybranych miejscach w pobliżu drogi. Rośliny poddano analizie w formie niemytej. Uzyskane dane zawartości Pb i Cd mieściły się w zakresie 4,65-106,30 i 0,165-1,615 mg/g suchej masy. Największą kumulację wykazywał C. dactylon, następnie liście N. oleander. Kora P. brutia oznaczała się najmniejszymi wartościami analizowanych metali.

The present investigation was undertaken in order to enlighten the pollution load of Halilurrahman lake in Turkey by investigating its physico-chemical parameters.The water analysis showed class I and II characteristics according to the international standards, but slightly higher levels of nitrate and chloride depict a contamination in its water. The levels of trace elements: Cr, Co, Bi, As, Se, Hg, Ba, Fe, Zn, Pb, Cd, Cu, Al and F as well as radionuclids like mU, 208n, 134CS, 214Bi and 4°K were determined in the sediments and different organs of fish specimen. Co and Cr levels were higher as compared to other trace elements. 137 Cs and 40K were detected both in the sediments vis-a-vis fish steak.

Przedstawiono badania ładunku zanieczyszczeń w jeziorze Halilurrahman poprzez analizę parametrów fizykochemicznych jego wody. Badana wodę zaliczono do I i II klasy czystości, jednak zawartość azotanów i chlorków przewyższała poziom określony dla tych klas. W osadach dennych oraz w różnych częściach ryb oznaczono stężenie pierwiastków śladowych: Cr, Co, Bi, As, Se, Hg, Ba, Fe, Zn, Pb, Cd, Cu, Al i F oraz radionuklidów,jak: 235U, 208Tl, 134CS, 214Bi i 40K. W porównaniu z innymi mikroelementami największe stężenie wykazywał Co i Cr. Zbadano również zawartość I37Cs i 40K w osadach dennych.
