“…Like organotins, this family of molecules, potentially used in certain automotive oils, is very poorly documented. To date, only one study has analyzed LAS in road runoff and pointed out much higher concentrations (43-590 µg/L) [28]. As expected, due to their physical-chemical properties, PAHs and PBDE are mainly detected in the particulate fractions (suspended solids or sediments) rather than the dissolved phase (Figure 2).…”

“…The non-quantification of oxygenated ethers in the runoff, although they are potentially emitted following the combustion of fuels, could be linked to their very rapid volatilization due to their physical-chemical properties. Previously reported concentrations of MTBE ranged from 0.03 to 1.9 µg/L [26][27][28]. A recent study indicated that the concentrations of oxygenated ethers were below 0.03 µg/L [20].…”

Although runoff from trafficked urban areas is recognized as a potentially significant pathway of micropollutants, runoff pollution remains poorly documented, except for relatively few historical pollutants such as some metals and hydrocarbons. Therefore, in this work, road and parking lot runoff from four sites with contrasting traffic levels were analyzed for a very broad spectrum of molecules and elements. A total of 128 pollutants and micropollutants were monitored, including inorganic (n = 41) and organic (n = 87) pollutants. Both the dissolved and particulate phases were considered. For a reduced number of samples, non-targeted screening by high-resolution mass spectrometry (HRMS) was carried out. For targeted screening, the contamination profiles were quite homogeneous, but the concentrations significantly differed between the different sites. Sites with the highest traffic density exhibited the highest concentrations for polycyclic aromatic hydrocarbons (PAHs), some traffic-related metals, alkylphenols and phthalates. Overall, for most micropollutants, the parking lot runoff exhibited the lowest concentrations, and the specificity of this site was confirmed by its HRMS fingerprint. Non-target screening allowed the sites to be discriminated based on the occurrence of specific compounds. Unlike the results of targeted screening, the HRMS intra-site variability was lower than its inter-site variability. Unknown substances were tentatively identified, either characteristic of each site or ubiquitous of all samples.

“…There is high variability in detergent formulation. However, the active molecule most used in these cleaning products belongs to the group of alkylbenzene sulfonates [24,25].…”

“…Depending on the species, the concentrations at which chronic effects are observed vary between 250 and 10,000 µg L −1 [46]. Additionally, these substances contribute to the permeation of other toxic compounds into aquatic animals [24]. Alkylbenzene sulfonates are mostly treated in wastewater treatment plants in an activated sludge process [47], and some of them are degraded by indigenous microorganisms when they reach the natural receiving environment.…”

Water is an essential resource for the functioning of society, where it is involved in key areas such as domestic use, agriculture, energy production, industry, and transport. Climate change exacerbates water scarcity. In the context of preserving water resources, effluents from the automobile sector need to be deeply considered due to their environmental impacts. This review focuses especially on the water effluents generated by car workshops. In car workshops, daily floor washing waters containing organic pollutants, either from vehicle components or from products used for maintenance and repair, can represent large volumes of water (between 15 L and 50 L per day) that are discharged into the wastewater system. These particular industrial organic effluents are not well characterized and can represent severe environmental risks. The aim of this review is to help automotive maintenance and repair professionals better manage these industrial organic effluents. We first describe the potential sources of organic pollution emissions in car workshops with the purpose of identifying the organic compounds to be monitored as a priority in the wash water. Then, we apply a risk prevention management tool, based on the criticality matrix, to identify products with a high risk of leaking onto the ground in order to limit organic pollutants at the source.

D'une façon générale, la température des eaux est influencée par l'origine dont elles proviennent Breton et al, 2010;Sablayrolles et al, 2011 (Abdoulkadri et al, 2015).…”

REMERCIEMENTS Ce travail a été financé par «Programme SAAGA» de la base aérienne du Burkina Faso. Les auteurs expriment leurs remerciements pour l'appui technique, matériel et financier dont ce travail a bénéficié. RÉSUMELa problématique de l'accès à l'eau constitue une préoccupation majeure pour tous, du fait qu'elle est étroitement liée à la santé et au développement socio-économique. L'accès à l'eau pour les populations rurales des pays en développement reste un défi à relever. Au Burkina Faso, malgré les efforts fournis par l'Etat et ses partenaires au développement, la rareté de la ressource demeure une réalité. Dans le cadre d'une gestion participative des eaux de pluie provoquées au Burkina Faso, un suivi de la qualité des eaux a été réalisé en campagne pluvieuse. Cette étude fait l'état des lieux de l'impact des opérations d'ensemencement des nuages du PROGRAMME SAAGA sur la pollution de l'environnement au Burkina Faso. L'objectif du travail est de déterminer le niveau de concentration en ions calcium (Ca Mots clés : Eaux de pluie, Ensemencement des nuages, Programme SAAGA, Ionométrie, voltamétrie cyclique, Burkina Faso.

The Access to water for rural populations in developing countries remains a challenge for the sustainable development despite the efforts deployed by the government and its partners to achieve the Millennium development goals, the lack of water remains a reality especially in Burkina Faso. As part of a participatory management of rainwater caused in Burkina Faso, monitoring the water quality was carried in the rainy season. This study is an inventory of the impact of clouds seeding program of "PROGRAMME SAAGA" on environmental pollution in Burkina Faso. The objective of this study is to determine the level of concentration of the calcium ions (Ca M.A.
