الملخص EN

The current study have been performed to evaluate the biological importance of aquatic plants as bio indicators for trace mental pollution in the orchards of date palm at Abu-Alkhaseeb area, Basrah governorate, Iraq.

Two different sits has been selected ,the first.

Site was an orchard of date palm with aquatic plants while ,the second site was without any aquatic plants .

A Nickel, Copper, cadmium, Lead, Zinc and Manganese have been examined in the soil, water and date palm parts including root and leaves, for both sits.

Four aquatic plants have been selected which were Carex burnnea variegata, Phragmites australis, Typha domingensis and Radix dulicis.

First site was distinguished by the low levels of trace mental pollution ,compared with the second site (without aquatic plants).

Hence, the values of trace mental were observed to decrease in irrigated water and leaves of date palm.

Thus explained by the fact that the leaves of aquatic plants absorbed large quantities of mental.

Summer season has the positive results among other season regarding the trace mental pollution.

Finally, the aquatic plant varied in their content of examined trace mental.
