    Abstract: The organic fertilizers help to sophisticate the soil structure by nourishing it, enhancing its productivity and at the same time protecting it from being eroded away. Nitrogen and phosphorus fertilizers are the major limiting factors in most soils. The highland vertisols of Ethiopia are prone to nutrient deficiency especially of N and P as the res... Show More

    Abstract: The accumulation of metalloids in the food chain can pose a great risk to human health and aquatic biota. The aim of this study was to evaluate the repartition, ecological and health risks of arsenic in surface sediments from a fluvial-lagoon environment, between the Comoé River and Ebrié Lagoon in Côte d'Ivoire. Arsenic contamination levels in sed... Show More
