Ce présent travail a pour objectif de quantifier la pollution d’une rivière face aux activités industrielles. Notre zone d’étude représente une très forte concentration en zones industrielles avec une domination du secteur textile. Ces industries déversent leurs eaux usées brutes dans la rivière Ikopa et entrainent la pollution de l’eau de la rivière. Pour bien mener cette étude, quatre points ont été analysés : en amont des rejets, les deux principaux points de rejets industriels et en aval des rejets (à environ 2 km). L’analyse a montré que les eaux usées industrielles ont des concentrations physico-chimiques relativement supérieures aux normes de rejets industriels selon la législation à Madagascar. Aucun suivi n’a été fait par les autorités concernées malgré l’existence des textes législatifs concernant les rejets et la protection de l’environnement. Face à cette problématique, la mise en place d’un système de traitement des eaux usées industrielles simple, efficace et facile à mettre en œuvre dans un pays en développement « les bassins de lagunage naturel » a été choisi.

La pratique du maraîchage occupe une place prépondérante dans le paysage de la ville de Ouagadougou. Il est mené autour des points d’eau pérenne et accessible, à l’intérieur comme à la périphérie de la ville. La présente étude a pour objectif d’évaluer des risques de contamination des sols et des plantes en ETM (Cd, Pb et Zn) sur les sites maraîchers de la commune de Ouagadougou. La méthodologie utilisée a consisté à réaliser une enquête auprès des exploitants, des acteurs et à des prélèvements des échantillons de sols, des eaux usées et des feuilles de laitue (Lactuca sativa) sur trois sites retenus. Les concentrations en éléments traces métalliques (ETM) des échantillons prélevés ont été analysées par spectrométrie d’absorption atomique. Les résultats des enquêtes ont montré que 88,5% des producteurs utilisent les produits résiduaires organiques (PRO) et 57,7% utilisent les eaux du canal central sur le site de Paspanga contre 78,8 % des producteurs utilisant les PRO et 100% les eaux usées du canal Est sur le site de Wayalghin. Il ressort que les sources de contamination sont liées aux apports massifs des PRO, aux infrastructures urbaines et services administratifs aux alentours, des tas de monticules sur les sites et à la qualité des eaux usées utilisées. Les résultats obtenus des analyses montrent une importante accumulation des ETM notamment le plomb par la laitue cultivée dans les sites de Paspanga et de Wayalghin. En effet, les teneurs moyennes en ETM atteignent respectivement 0,5212 et 0,5353 mg/kg de poids frais dépassant les valeurs limites réglementaires de l’OMS et de la CE. De fortes valeurs cadmium non loin du seuil légal de la CE sont enregistrées dans les sols sur l’ensemble des trois sites. Une teneur élevée du Cd (7,91 µg/L) proche de la valeur seuil de la FAO et CE a été également observée dans les eaux d’irrigation du site de Kossodo. Les teneurs élevées en Zinc (236 mg/kg) dans le sol du site de Paspanga et dans la laitue sur le sur les sites de Wayalghin et Paspanga, non loin de la teneur seuil de la FAO/OMS ont été enregistrées. Comparativement aux normes de la CE, le Pb et le Zn dans le sol du site de Paspanga sont également situés dans les limites de la CE. La détection des ETM à des concentrations supérieures aux normes autorisées par la FAO et CE pourrait poser des problèmes de toxicité pour les plantes, les animaux et des effets néfastes sur la santé humaine. Les concentrations proches des valeurs seuils recommandées, méritent d’être surveillées par la prise des mesures pour limiter les contaminations. Une limite de nos travaux est que les enquêtes et des prélèvements des feuilles de laitue n’ont pas été effectués sur le site de Kossodo car le site était inexploité au moment du stage.

Lose yourself in the vast sewer networks that lie beneath the world's great cities - past and present. Let detailed archival plans, maps and photographs guide you through these subterranean labyrinths - previously accessible only to their builders, engineers and, perhaps, the odd rogue explorer. This execrable exploration traces the evolution of waste management from the ingenious infra-structures of the ancient world to the seeping cesspits and festering open sewers of the medieval period. It investigates and celebrates the work of the civil engineers whose pioneering integrated sewer systems brought to a close the devastating cholera epidemics of the mid-19th century and continue to serve a vastly increased population today. And let's not forget those giant fatbergs clogging our underground arteries, or the storm-surge super-structures of tomorrow.

"The Circular Economy: Case Studies about the Transition from the Linear Economy explores examples of the circular economy in action. Unlike other books that provide narrow perceptions of wide-ranging and highly interconnected paradigms, such as supply chains, recycling, businesses models and waste management, this book provides a comprehensive overview of the circular economy from various perspectives. Its unique insights into the approaches, methods and tools that enable people to make the transformation to a circular economy show how recent research, trends and attitudes have moved beyond the "call to arms" approach to a level of maturity that requires sound scientific thinking."
