Bioaccumulation of lead and Chrome in Celery plant (Apium graveolens L.)

Celery is one of the most important table plants in the world, this plant tends to collect many minerals from the surrounding environment, and one of these minerals is lead and chrome, which they considered toxic metals if they accumulate in this plant and accordingly three different areas were chosen for the cultivation of this plant. It was divided into areas contaminated with lead and chromium, which were close to the cement factory street and Bahr al-Najaf area polluted with sewage water and its air polluted by the smoke of bricks. The celery leaves and the soil planted in this sites were collected in December of the year 2020, for three replicates from each region, they were digested and the concentration of lead and chromium were detected. The results showed that the concentration of studied elements in the soil and plants of Bahr Al-Najaf < Al Ma’mal Street < Al Bu Hadari, and this difference was significant (< 0.05). Also, the results showed that the biological concentration of these elements were large in Bahr Al-Najaf area compared to Al-Ma'mal Street and Al-Bu Hadari area. Accordingly, the study recommends not to plant crops in polluted areas and the necessity of chalking the concentration of these elements of the soil and the surrounding environments of the plants before starting cultivation.
