تاثير عوارض طبيعي بر تجمع آلاينده ها در اراضي تحت كشت گندم در حاشيه بزرگراه بهشهر - آمل

Effect of natural altitudes on accumulation of pollutants in wheat agricultural farms at the adjacent area of Behshahr - Amol highway

In this project the concentration of lead in wheat and soil of adjacent farms of Behshahr Amol highway, as a heavy traffic transport means area, was studied for one year. For determination of lead content in agricultural product and soil in agricultural area adjacent to the main road, with considering the natural altitudes, 3 stations at area near the mountain and 3 stations at an open area (field) were selected and at each stations with a distance of 10, 20, 30, 50, 100 and 150 m from the main road, the soil and wheat sample were collected. The results of the statistical analysis (LSD - test) stated that there is a significant variations (with % 95 assurity level) between the lead content of wheat and soil at 10, 20 and 30 m with those of at 100 and 150 m distance. On the other words, the concentration of lead in all samples are decreasing, with increasing distance from the main road. The results of the F - test on effect of mountain on accumulation of lead in agricultural farm, stated that, there is a significant variations of %95 assurity level, of lead content between the two considered agricultural farms (near mountains, and open areas - field). This means that the mountains and other natural altitudes of the area are having a good effect on accumulation of lead results from the traffic transport means.
