“…The data illustrated in the figure (Figure 3) are expressed as minimum and maximum values for the data reported in the literature. 101,155,[164][165][166][167][174][175][176] It has to be mentioned that Lake Qarun has no connection either with the River Nile or the Mediterranean Sea. 176 On the other hand, Lake Maryout is relatively far of the outlet of Rosetta branch (see Figure 1).…”

“…From the data available in the literature, [165][166][167]175,176 it was possible to estimate the relative accumulation of OCP residues in water, fish, and sediment from River Nile, Lake Manzala, and Lake Qarun (Table 7). Similarly, the relative accumulation of PCBs was estimated for different samples from River Nile, Lake Manzala, and Mediterranean Sea (Table 8); based on data published by El-Gendy et al 164 ; Yamashita et al 166 ; Abbassy et al 175 ; Badawy and Wahaab 183 ; Abd-Allah and Abbas 174 ; and Abd-Allah and Ali. 181 The data presented in Tables 7 and 8, generally, reveal that residues of OC pesticides and PCBs showed higher levels in sediment followed by fish and then water.…”

“…211 Monitoring of some PCBs congeners in different components of the aquatic ecosystem representing River Nile branches and estuaries, lakes, and some locations on the Mediterranean and the Red Seas has been carried out by several investigators. From the data published between 1985 to 2005, 88,101,155,163,164,166,168,170,174,175,[180][181][182][183][212][213][214][215] we concluded that the highest concentration of PCBs in water existed in the Nile Estuary at Damietta (851.0-1030.0 ppb), while the highest concentration in fish was seen in samples from the Red Sea coast (6.7-66.4 ppm). The Nile Estuary at Damietta receives industrial wastes from the Delta region (see Figure 1).…”

Persistent organic pollutants (POPs) are organic (carbon-based) compounds that include synthesized substances (pesticides and polychlorinated biphenyls [PCBs]) and other by-product substances generated as a result of human and natural activity (dioxins and furans). Extensive scientific studies have shown that POPs are some of the most dangerous pollutants released into the environment by humans. Great efforts have been made since the early 1960s to enhance chemical management and safety issues. Various conventions have been adopted for this purpose: the Stockholm Convention (SC) is one of the well-known meetings in this context. The SC on POPs (May 2001) focuses on reducing and eliminating releases of 12 POPs coined the ‘Dirty Dozen’ by the United Nations Environment Program (UNEP). Persistence of such chemicals in soils, air, and water, together with natural processes such as evaporation to the atmosphere and washout by rain and flood, give rise to their ubiquitous distribution in the environment and eventual penetration into food chains and bio-accumulation in humans. Public concern about contamination by POPs increased recently because several of these compounds are identified as hormone disruptors, which can alter normal function of endocrine and reproductive systems in humans and wildlife. African countries are using pesticides, such as dichlorodiphenyltrichloroethane (DDT), lindane, toxaphene, endrin, dieldrin, heptachlor, since more than 50 years for combating agricultural pests and controlling disease vectors, especially malaria. The way in which pesticides are used in Africa caused serious environmental and health problems much more than elsewhere. These problems are represented by accumulation of organochlorine pesticide (OCP) residues in different environmental samples and hosting of at least 50,000 tons of obsolete pesticides, as well as tens of thousands of tons of contaminated soil. Within the framework of the Africa Stockpiles Program (ASP), huge quantities of pesticidal POPs have been completely or partially destroyed in a number of African countries (e.g. Egypt, Namibia, Niger, Senegal, Seychelles, South Africa, Sudan, Tanzania, Uganda, Zambia). At regional level (i.e. African Countries), a strategic plan for monitoring and getting rid of POPs in the continent should be set up and implemented through coordination between all governments. Among issues of top priorities are to find alternative non-combustion technologies for disposing obsolete pesticides, and to use alternative control measures for mosquitoes’ management and other vector-borne diseases.
