Description

Bioaccumulation des mtaux toxiques dans les organismes marins by Maha Ahmed Mohamed Abdallah Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Les polluants qui pénètrent dans les eaux côtières et les estuaires causent de graves problèmes, entraînant des dommages considérables à la vie et aux activités des organismes aquatiques vivants, voire une mortalité massive. Parmi les polluants, l'accumulation de métaux lourds dans les écosystèmes marins revêt une importance mondiale. La contamination par les métaux n'a pas fait l'objet d'études approfondies dans les zones côtières égyptiennes bordant la mer Méditerranée, qui sont soumises à des rejets importants de polluants. Ces effluents sont riches en différents métaux lourds, qui sont transportés soit dissous dans l'eau, soit en suspension dans les sédiments, et stockés dans les sédiments du fond, modifiant ainsi leurs caractéristiques physico-chimiques naturelles. Les processus de bioaccumulation des métaux lourds peuvent s'avérer dangereux pour la population locale vivant dans cette région et utilisant le littoral pour la pêche et les loisirs. Le dépassement de certaines valeurs de concentration en métaux dans les poissons entraîne des perturbations mortelles. Dans la plupart des cas, les poissons provenant d'eaux contaminées par des métaux sont sans danger pour la consommation humaine en raison de la faible accumulation de métaux (à l'exception du mercure) dans les tissus musculaires. Cependant, ces poissons peuvent constituer un risque potentiel pour les poissons prédateurs qui se nourrissent de poissons contaminés.

  1. Seller sent me the wrong book, but the book they sent sounded interesting enough for me to keep it. I still contacted the seller and communication was fast and professional. They apologized for sending me the wrong book and said I could return it for a refund. I told them that I liked the book they sent me and wanted to keep it. They were happy. Told them thank you and happy new year. People make mistakes, but the fact that this seller was quick and professional and apologized made a difference.

  2. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  3. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.
