This study deals with spatial and temporal distributions of organic and inorganic
phosphorus in sedimentary columns from Al-Kabir Al-Shimaliand Al-Hussain estuaries,
during the period March 2013- February 2014.
Organic phosphorus concentrations ra
nged between (2.0 - 207.6) μg/gin sediments
from Al-Kabir Al-Shimali estuary, and from (1.7 –130.9) μg/gin sediments from
Al-Hussainestuary. Sediment content from inorganic phosphorus ranged between
(12.4 – 371.2)μg / g at sediments from Al-Kabir Al-Shimali estuary, and from
(2.0 - 242.6)μg /g at Al-Hussain estuary. Granular composition of sediments did not play
a significant role in the temporal and spatial distributions of organic and inorganic
phosphorus.
In general, organic and inorganic phosphorus concentrations decreased gradually
from winter to summer, and from surface layers of the sedimentary column towards the
deeper layers.
The ratiobetween inorganic and organic phosphorus increasedfrom river into marine
sediments. In addition, this ratio increased gradually as the sedimentdepthincreased, and
was high in winter and low in summer.
Due to the lack informations on Biochemical of jellyfish in the Syrian waters, the
aim of this paper is determining the nutritional value and organic content for each of the
species Rhopilemanomadica, Pelagianoctiluca and Aequorea forskalea, and co
mpared the
biochemical composition of the three types , so the comparison showed clear differences in
the content of organic material, the sugar were the most concentrated in the three species
and lipid comes in second class, and then followed by the protein content and organic
carbon.A.forskalea was the most containing sugar and R.nomadica the most lipids content,
and P.noctiluca were the most protein content.R.nomadic was the highest content in
organic carbon, R.nomadica and P.noctiluca were convergent contents of organic
phosphorus, while the least contain of organic nitrogenwas in A.forskalea.
