In industrial areas, tree leaves contaminated by metals and metalloids could constitute a secondary source of pollutants. In the present study, water extraction kinetics of inorganic elements （IE： Pb, Zn, Cd, As, Fe and Mn）, dissolved organic carbon, pH and biological activity were studied for industrial contaminated poplar leaves. Moreover, the distribution of the IE through the size fractions of the associated top soil was measured. High quantities ofMn, Zn and As and polysaccharides were released in the solution from the strongly contaminated leaves. The kinetic of release varied with time and metal type. The solution pH decreased while dissolved organic contents increased with time after 30 days. Therefore, these contaminated leaves could constitute a source of more available organic metals and metalloids than the initial inorganic process particles. However, the distribution of the IE through the size fractions of the top soil suggested that a great part of the released IE was adsorbed, reducing in consequence their transfers and bioavailability. It＇s concluded that mobility/boioavailability and speciation of metals and metalloids released from the decomposition of polluted tree leaves depends on soil characteristics, pollutant type and litter composition, with consequences for environmental risk assessment.

Introduction: This study aimed to identify road safety interventions implemented in Africa and to analyze their effectiveness in reducing road crashes, injuries, disabilities and deaths. Materials and Methods: This is a systematic review including articles relating to the evaluation of road safety interventions implemented in Africa that were searched on electronic databases: PubMed, Scopus, Lissa, Google Scholar, and African Journals Online. Selection of articles and data extraction was conducted by two pairs of reviewers. Data quality was checked according to the type of study. A qualitative analysis of the data was carried out and a narrative approach was adopted to describe and synthesize the results. Results: A total of twenty-nine articles were selected including one cross-sectional study, seven time series, twenty-one quasi-experimental studies of which six randomised and fifteen non-randomised studies. The type of interventions evaluated was aimed at all types of users and was based on different interventions such as institutional strengthening, law enforcement, awareness raising, training or user education, vehicle maintenance and infrastructure improvements. For fourteen studies all the expected indicators had changed favourably and for twelve the indicators had partially changed. The studies that showed significant change were institutional strengthening, law enforcement, awareness raising, training, or user education interventions, development of Uber transport services, distribution of equipment, and a combination of interventions. Conclusion: This situation is indicative of insufficient policy investment in research but also in the field of road safety in general.

The distribution of the metallic trace elements (MTE) Zn, Pb and Cd in a sludge-amended soil and their partitioning in specific soil microystems are studied by comparing their contents in amended and control soils. This comparison is achieved at the metric scale of the bulk soil horizons and at the micrometric scale of the weathering microsites (weathering rock-forming minerals and their specific weathered products). The chemical analyses of the MTE in the bulk samples do not show any anthropic contamination of the amended soil with repeated sewage sludge spreading. The chemical analyses of the

This article exposes the beginnings of a new field which could be named as ＂plasmomechanics＂. Plasmomechanics comes from the convergence between mechanics and plasmonics. Here we discuss a relatively recent topic whose technolo- gical aim is the development of plasmonic strain sensors, The idea is based on the ability to deduce Au nanoparticles （NPs） distance distributions from polarized optical extinction spectroscopy which could thus give access to material strains. Variations of interparticle distances distributions can indeed lead to variations of plasmonic coupling and thus to material color change as shown here experimentally and numerically for random Au NP assemblies deposited onto elastomer films,
