Achievements in the Life Sciences Volume 9, Issue 2, December 2015, Assessment of Organochlorine Pesticide Residues in Water, Sediments and Fish from Lake Tashk, Iran. Abstract In this study, the levels of organochlorine (OC) pesticide residues in Lake Tashk have been investigated using water, sediment and fish (carp) samples as a case study to find out the extent of pesticide contamination and accumulation in the lake.
Six OC pesticides namely DDT, DDE, lindane, endosulfan, heptachlor and chlordane were analyzed in four sites at four seasons. Water samples were processed using a liquid–liquid extraction technique and gas chromatograph equipped with electron capture detector (GC-ECD). Soxhlet extraction was used for fish and sediment samples followed by clean up and gas chromatograph. DDE was the predominant residue in all the samples analyzed, at the mean concentrations of 0.075 ppb, 8.750 ppb and 4.446 ppb in water, sediment and fish samples, respectively.
Keywords Organochlorine residues; DDT; Soxhlet; GC-ECD; Lake Tashk Introduction Organochlorine (OC) pesticides are among the agrochemicals that have been used extensively for long periods. The Egyptian Journal of Aquatic Research Volume 40, Issue 2, 2014, Organochlorines and their risk in marine shellfish collected from the Mediterranean coast, Egypt. Abstract Shellfish is a useful tool for active environmental biomonitoring.
According to levels of persistent organic pollutants (POPs) in shellfish, we can calculate the risk observed for public health. Accordingly, this study covers the determination of POP concentration in some shellfish collected from the Mediterranean coast of Egypt. The obtained results revealed that the concentrations of total OCPs range from 47.07 ng g−1 to 113.9 ng g−1 with an average of 85.77 ng g−1. The organochlorine pesticide (OCP) concentration in collected shellfish followed the order: Total cyclodienes < PCBs < DDTs < HCHs. Keywords Shellfish; Bivalves; Biomonitoring; Organochlorine; Mediterranean; Egypt Introduction Over the last decades, increasing attention has been paid to the occurrence of persistent organic pollutants (POPs) in coastal and estuarine environments. Biota could potentially acquire PCBs from three sectors in the environment: atmosphere, water and food.
Material and methods Samples Table 1. The Egyptian Journal of Aquatic Research Volume 40, Issue 4, 2014 Distribution of heavy metals in seaweeds collected along Marsa-Matrouh beaches, Egyptian Mediterranean Sea. Abstract The distribution of Cd, Cu, Fe, Ni, Pb, and Zn concentration in two seagrass species in addition to six species of marine macro algae: Cystoseira sp., Gelidium crinale, Laurencia obtusa, Gracilaria verrucosa, Jania rubens, and Enteromorpha compressa collected along Marsa-Matrouh coastal waters (Egypt) were determined by Flame Atomic Absorption Spectrometry.
The recovery study was carried out using a certified reference material NMIJ CRM 7405-a. The obtained heavy metal contents indicated that different species demonstrated various degrees of metal accumulation. In general, El-Boussit station recorded the highest concentrations among the all studied stations. There was a positive correlation between Fe concentrations in the seaweeds and those of Cu and Pb indicated the same source of these metals and/or synergistic interaction between these metals. Keywords. JOURNAL OF FOOD SCIENCE - 2015 - Seasonal survey of contaminants (Cd and Hg) and micronutrients (Cu and Zn) in edible tissues of cephalopods from Tunisia: assessment of risk and nutritional benefits.
Abstract : Concentrations of cadmium (Cd), copper (Cu), mercury (Hg) and zinc (Zn) were determined by atomic absorption spectrophotometry in the muscle tissues (arms and mantle) of three commercial cephalopods (Loligo vulgaris, Octopus vulgaris and Sepia officinalis) caught in three different Tunisian coastal regions.
The highest concentrations found correspond to the essential elements Cu and Zn. Octopuses and cuttlefish showed the highest levels of those elements while squid presented with significantly higher values of Hg in both muscular tissues. This may be related to different feeding behavior and detoxification processes among benthic and pelagic cephalopods. Variation of element concentrations between seasons was different between species and seemed to be mostly dependent on the sampling site.
