valuation de la pollution des sols par les mtaux lourds dans une cimenterie ougandaise by Henry Olwenyi Estimated delivery 3-12 business days Format Paperback Condition Brand New Description La contamination des sols par les métaux lourds est l'un des principaux problèmes de santé dans le monde entier en raison de leurs effets cumulatifs à long terme. Cette étude a examiné les concentrations des 3 métaux lourds sélectionnés (Pb, Cr et Cd) dans les sols autour de la cimenterie de Tororo dans le sous-comté d'Osukuru, district de Tororo, dans l'est de l'Ouganda. Trois échantillons de sol ont été prélevés de chaque côté de la cimenterie (Est, Ouest, Sud et Nord) à des distances variables de (100, 200 et 300) m du mur d'enceinte de la cimenterie, soit 12 échantillons de sol au total prélevés autour de la cimenterie, tandis que 3 échantillons de sol ont été prélevés sur le site témoin de Chamilula. Des poids connus d'échantillons de sol séchés au four ont été digérés à l'aide d'acide nitrique et d'acide chlorhydrique. Les digestats ont été analysés pour les métaux lourds sélectionnés à l'aide d'un spectrophotomètre d'absorption atomique à flamme. Les concentrations de métaux autour de la cimenterie variaient de 7,80 à 22,80 mg/kg pour le Cr, de 0,76 à 1,49 mg/kg pour le Cd et de 29,80 à 61,60 mg/kg pour le Pb, tandis que sur le site témoin de Chamilula, elles variaient de 4,70 à 4,80 mg/kg pour le Cr, de 0,10 à 0,11 mg/kg pour le Cr et de 11,59 à 11,70 mg/kg pour le Pb.

  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.
