Autor: Abdelghani Chafik, Samir Benbrahim Mostafa Sifeddine, Mohamed Cheggour, Daniel Cossa

Publikováno v: Aquatic Living Resources. 14:239-249

The quality of Moroccan Atlantic coastal wasters was monitored from 1993 to 1997 by measuring hydrological parameters (dissolved oxygen, suspended particulate matter, phosphates, and nitrates), and using the mussel Mytilus galloprovincialis as a quan

Phosphate industry discharges and their impact on metal contamination and intertidal macrobenthos: Jorf Lasfar and Safi coastlines (morocco)

Autor: Mohamed Cheggour, A. Boumezzough, W.J. Langston, H. Texier, H. Idrissi, A. Chafik

Publikováno v: Toxicological & Environmental Chemistry. 70:159-179

At Jorf Lasfar and Safi, on the Moroccan Atlantic coastline, there are chemical industry plants that produce phosphate derivates including phosphoric acid and fertilizers, together with by‐products such as sulphuric acid. The liquid effluents of th
