الملخص EN

This study aims to show the spatial patten of the concentrations of some heavy metals in the waters of the Chibayish marshes and the pollution sources that cause them.

As well, it aims to conduct to an environmental assessment of pollution with these elements, their impact on the aquatic and plants life in the study area.

25 water samples were collected during the year 2019.

The data were divided into 15 samples representing the sources of water pollution and 10 samples from different places of the marsh surfaces of the study area.

These samples were examined in the laboratory by procedure of digestion and with an atomic absorption spectrometer.

The analysis of data adopted the following heavy elements: Ni concentrations ranged between (0.0937 - 0.0136 mg / l).

Pb concentrations ranged between (0.2197-0.0923 mg / l).

Fe concentrations varied between (0.1201-0.003 mg / l).

Cd concentrations ranged between (0.0226- 0.0017 mg / l).

The present study showed high concentrations of heavy elements in the sources of pollution compared to the water of the marshes.

However, Pb and Cd concentrations, in particular, were recorded in the water samples of the studied marshes, which significantly exceeded the recommended environmental standards.

The danger of these pollutants lies when they bio-accumulate, and their accumulation for a long period of time may lead to their transformation into carcinogens that harm human health and other organisms alike.
