xiiSUMMARYSULFUR ACCUMULATION OF MARITIME PINE (Pinus pinaster AIT.)NEEDLES ON KEFKEN / IZMIT SECTION IN KOCAELI PENINSULADepending on the rapidly growing population, the demand to wood material increasesday by day in our country. Plantation studies has begun with fast growing native andexotic tree species by the end of 1960s to meet wood material requirements. In Izmitand Kefken region in Kocaeli Peninsula, plantations were done by using native speciesof Pinus nigra, Pinus brutia and exotic tree species of Pinus pinaster and Pinus radiata.This study was carried out in the plantation areas of maritime pines on Kefken/Izmitsection in Kocaeli Peninsula. On this section, from 47 sample plots of 5 different areasthe sample needles were taken. On this samples the effects of air pollution on plantationareas were researched by sulfur analysis.The samples were dried at 650C and ground. The sulfur values of these samples weredetermined by the barium sulphate and gravimetric sulfur determination method whichwas explained in detail in the third section of this study. In this way, the harmful effectsof air pollution on maritime pines and drying of trees as a result of these effects weretried to determine.In the sample areas of Izmit and Kefken sections, especially in Izmit air pollution is onhigh levels. Industrial plantations and the air pollution coming from Karadeniz areeffective on this level of Izmit area. Effective and wide spreading air pollution isoriginated from SO2 gas, especially. CO2 absorption in pine needles and taking SO2 gasfrom air in the respiration process, causes H2SO4 forming in the needle and decrease inwood production. This situation were explained in the section of discussion and result,in detail.As a result of this study, in maritime pines sulfur amounts were found out as on harmfullevels. But, harmful effects of SO2 in the arid region of South were determined higherthan the humid region of North. In addition to this, harmful insects population increasedin the South and damage of both SO2 and insects affected the health of the maritimepine trees and dried them.viii
