Odours are powerful stimuli that can evoke emotional states, and support learning and memory. Decades of research have indicated that the neural basis for this strong “odour-emotional memory” connection is due to the uniqueness of the anatomy of the olfactory pathways. Indeed, unlike the other sensory systems, the sense of smell does not pass through the thalamus to be routed to the cortex. Rather, odour information is relayed directly to the limbic system, a brain region typically associated with memory and emotional processes. This provides olfaction with a unique and potent power to influence mood, acquisition of new information, and use of information in many different contexts. including social interactions. Indeed, olfaction is crucially involved in behaviours essential for survival of the individual and species, including identification of predators, recognition of individuals for procreation or social hierarchy, location of food, as well as attachment between mating pairs and infant-caretaker dyads. Importantly, odours are sampled through sniffing behaviour. This active sensing plays an important role in exploratory behaviours observed in the different contexts mentioned above. Odours are also critical for learning and memory about events and places and constitute efficient retrieval cues for the recall of emotional episodic memories. This broad role for odours appears highly preserved across species. In addition, the consistent early developmental emergence of the olfactory function across diverse species also provides a unique window of opportunity for analysis of myriad behavioural systems from rodents to nonhuman primates and humans. This combined with the relatively conserved organization of the olfactory system in mammals, provides a powerful framework to explore how complex behaviours can be modulated by odours to produce adaptative responses, and to investigate the underlying neural networks. In this research topic, we welcome original and review articles, as well as opinion, methods and modelling papers from both human and animal research, covering the following issues (although the list is not exhaustive):• Neural and pharmacological bases of olfactory memory : in adulthood and through development• Olfactory-based social interactions: mother-offspring bonding, pair bonding, peer recognition, social hierarchy, social transmission of fear…• Emotional olfactory memory: conditioned odour fear, unconditioned odour fear, alarm pheromones…• Sniffing behaviour and its modulation during olfactory learning and/or social behaviours. The goal of this Research Topic is to bring together cutting edge research on diverse species and developmental stages, highlighting convergence and divergence between humans and animals to facilitate translational research.

Environmental odour is perceived as a major nuisance by rural as well as urban populations. The sources of odourous substances are manifold. In urban areas, these include restaurants, small manufacturing trades, and other sources, which might cause complaints. In the suburbs, wastewater treatment plants, landfill sites, and other infrastructures are the expected major odour sources. These problems are often caused be the accelerated growth of cities. In rural sites, livestock farming and the spreading of manure on the fields is blamed for severe odour annoyance. In fact, environmental odours are considered to be a common cause of public complaints by residents to local authorities, regional, or national environmental agencies. This Special Issue of Atmosphere will address the entire chain, from the quantification of odour sources, abatement methods, the dilution in the atmosphere, and the assessment of odour exposure for the assessment of annoyance. In particular, this Special Issue aims to encourage contributions dealing with field trials and dispersion modeling to assess the degree of annoyance and the quantitative success of abatement measures.

This book presents an introductory editorial paper and publications referring to current problems and challenges in the field of wastewater treatment. The published articles cover a wide range of topics (reducing the concentration of hydrogen sulfide in biogas and decreasing release of phosphate into a sludge liquor at WWTPs; water ecosystem protection from antibiotics through the use of AOP methods; tertiary wastewater treatment in bio-filtration systems assisted by the addition of hydrogen peroxide to stimulate microbial activity; odor removal using biological methods; the impact of WWTPs on the environment by taking into account energy consumption, noise, and the formation of bioaerosols; and odor nuisances), which show significant progress in the research and implementation of innovative solutions in wastewater treatment technology.

Les produits biologiques liés à l'alimentation, aux libations, aux fumigations, aux soins et à la beauté du corps jouent un rôle considérable dans la vie des peuples de la Méditerranée antique et ont aussi leur place dans les différentes étapes des rituels funéraires, de la préparation du corps jusqu'à la visite à la tombe.Produits périssables, ils ne laissent que peu de témoignages archéologiques sous la forme de restes fauniques et végétaux et de contenants en céramique, en métal ou en verre.Cet ouvrage collectif, riche de la collaboration d'une cinquantaine d'archéologues français, italiens et suisses, est la publication du programme MAGI, financé par l'ANR.Grâce à l'association de trois unités mixtes de recherche publiques et d'un laboratoire privé, le programme a mis en œuvre durant quatre ans, de 2013 à 2017, une approche transdisciplinaire combinant chimie organique et archéobotanique pour identifier les matériaux et produits biologiques en contexte funéraire en Gaule, en Italie péninsulaire et en Sardaigne, de la fin de l'âge du bronze jusqu'au début de l'époque romaine, et cerner leurs usages rituels
