Detection of Organochlorinated Pesticides residue in sediments and some mollusks of Tartous coast

Concentrations of eight chlorinated pesticides: namely, gamma HCH, Heptachlor, heptachlore epoxide, aldrin, dieldrin, 4,4-DDE, 4,4-DDD, and 4,4-DDT were studied in some mollusks species Monodonta turbinata, Brachidontes variabilis , Patella caerulea, Trochus erithraeus, Strombus persicus and in sediments taken from five different locations: Assin estuary, Jobar estuary, Banias Thermal Electricity Station, Albasia, and Mirkiya River estuary. Sampling was performed at six different times during the period 2006-2007. Results indicated that Assin estuary contained the highest level of contamination followed by Jobar estuary and Mirkiya estuary where sampled mollusks species contained various concentrations of all of the studied pesticides. At Banias Thermal Electricity Station samples showed contamination with heptachlore and heptachlore epoxide only, whereas the concentration of pesticides at Albasia location, much lower than the other locations.

Using of network for the monitoring of some of organic pollutants in the Syrian marine environment

In This study it has been uses a network for monitoring the pollution with organochlorine pesticides in There marine stations at Lattakia coast: Fishing port, AfamiaCoast, High Institute Of Marine Research Coastusing Cages contained species of musselswitch are filter feeders Brachidontes varibilis. Samples had been collected from Lattakia coast. The results showed a great efficiency of the made network for monitoring the organic pollution in marine environment. It has been recorded a concentration of DDTs is accumulated lower than 2ng/g , Endosulfane and HCB is lower than 1 ng/g too. The results showed that the HCH compounds is dominant in all stations.organochlorine pesticides is accumulated mostly in the biota of station Fishing port, Afamia Coast
