Nutrient contamination assessments in the three West African tropical Comoé, Bandama, and Bia Rivers (Côte d'Ivoire) were performed from March 2016 to March 2018. Five stations per river were sampled. Nutrients spatio-temporal distributions were mapped and showed nitrogen concentrations (nitrite 0.001 to 0.025 mg/L NO 2 - -N, and nitrate 0.26 to 3.60 mg/L NO 3 - -N) increased significantly with rainfall contrary to phosphorus (0.01 to 0.12 mg/L P). The Chl-a and TSI tsr data revealed the hypereutrophic status of rivers. Moreover, N:P mass ratio suggests nitrogen as the main limiting factor of primary production during the low (March) and high flow periods (October-November), while phosphorus is the limiting factor in June, at the high flow beginning. The land uses around watersheds were the main sources of phosphorus and nitrogen enhancing the rivers' eutrophication. Phosphorus and nitrogen fluxes were related to leaching river catchments and were significant sources of nutrients to the Atlantic Ocean., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Despite increasing mining activities, and fertilizer and pesticide use in agriculture, little information is available on the status of metal(loid) contamination in rivers in West Africa. Sixty water samples were collected from three significant rivers (the Bandama, Comoé, and Bia Rivers) in Côte d'Ivoire, the world's top cocoa producer, to examine As, Pb, Cu, Fe, Cd, and Zn concentrations, partitioning, and distribution in suspended particle-size fractions. The results showed higher total metal(loid) concentrations during the dry and flood seasons than during the rainy season. Significant As and Pb concentrations, moderate Cu and Fe concentrations, and low Zn concentrations were observed during the flood season. The metal(loid) concentrations decreased upstream to downstream primarily due to increased deposition through flocculation. Inverse or no obvious spatial trends often were observed, indicative of local contamination from anthropogenic activities. The suspended solid phase and the strength of metal affinity to the particles controlled the metal(loid) concentrations. Furthermore, total metal(loid) concentrations increased significantly with decreasing suspended particle-size fractions. The results underline that As and Pb contents in the Comoé and Bia Rivers threaten the health of at least 3 million people in southeastern Côte d'Ivoire. Filtering river waters before use will significantly reduce human health risks.

Objectives: Arterial embolisation (AE) plays a major role in current practice in the management of postpartum haemorrhage (PPH) that fails to respond to conservative treatment. While its benefit is well known, long-term outcomes of AE have been poorly investigated. The objective of this review is to assess its potential complications and long-term effects on the patients' quality of life., Methods: Using the terms "embolisation" and "postpartum haemorrhage", we searched the Cochrane Central Register of Controlled Trials, Medline and PubMed for published studies. We limited the search to articles in English and French reporting "complications", "fertility", "menstruation" or "menstrual cycle" in humans. To ensure completeness, the references of extracted articles and review articles were also searched., Results: The fertility rate in patients attempting another pregnancy reaches 70-80 %. Pregnancies following AE for PPH are not associated with a higher rate of intrauterine growth restriction. Pathological placentation (placenta accreta/increta/percreta) occurs more frequently after AE than in the general population. Psychological wellbeing, post-traumatic stress and sexual dysfunction after a life-threatening PPH requiring AE will require further investigation., Conclusion: AE does not appear to adversely affect menstrual cycle, fertility and subsequent pregnancies, but may affect placentation. The experience of a life-threatening PPH, however, might prevent couples from pursuing another pregnancy., Key Points: • Embolisation for PPH does not adversely affect menstrual cycle and fertility • Experience of life-threatening PPH might prevent couples from pursuing another pregnancy • Pathological placentation seems to occur more frequently after embolisation for PPH.
