Chemical sensors for environmental monitoring: Limitations, challenges and prospects
There is a window of opportunity now to tackle the challenges in environmental monitoring and respond to:
- The current evolution of environmental standards with a considerable drop in the permissible limits of harmful substances in environmental samples,
- The need to monitor pollutants concentrations in air, soil and rivers in situ and in real-time,
- The increased need for air quality monitoring in homes and public buildings, mainly after the pandemic of Covid-19.
The most promising devices that could meet all these challenges are chemical sensors. A bibliographic search on SciFinder (for the period 2020-2022) combining the concepts "Chemical sensors" and "Environmental monitoring" leads to a rather “impressive” number of references: more than 180,000 papers published in peer-reviewed journals, 35,000 patents and 17,000 reviews.
However, with such a craze and despite undeniable progress in surface functionalization techniques, transduction mechanisms, and lab-on-chip design, the chemical sensors market is still limited.
This presentation concerns the limitations, challenges to be met and prospects of chemical sensors. What improvements need to be done to make them THE analytical devices of choice for environmental monitoring?

Pressure retarded osmosis (PRO) Technology for sustainable osmotic power generation from desalination waste
Pressure retarded osmosis (PRO) is a membrane-based osmotically driven process that harnesses the energy of mixing between low-salinity and high-salinity streams for producing mechanical energy. In this PRO process, water permeates through a semipermeable membrane from a lower concentration feed solution into a higher concentration draw solution, partially pressurized, possibly brine. As a particular free energy, the salinity gradient energy from saline solutions with specific concentrations has lately been assured as a source of renewable energy. This work explores the latest advancements as well as different application of the PRO process along with the analysis of potential energy that is harvested from the salinity gradient resources in a multi-stage and single-stage PRO processes. A significant challenge faced by the PRO process is obtaining a suitable commercial membrane that consolidates the features of reverse osmosis membrane (for withstanding the hydraulic pressure) and forward osmosis membrane (to reduce the concentration polarization phenomenon). In order to address the above challenge, information on the advanced lab-fabricated membranes and commercially available membranes are presented in the current work. The huge possibility of PRO technology is introduced in the current work by interpreting the PRO desalination systems, process design, salinity gradient resource energy of pretreatment, and dual-stage PRO (DSPRO) process. It is expected that this work could help in extensively understanding the PRO process and therefore provide crucial information for stimulating further research and development.

Literature review on test systems for the identification of the effects of endocrine active substances on soil invertebrates
In the last 20 years, a considerable number of studies have addressed possible endocrine disrupting chemicals (EDCs) in the environment. However, little attention has been paid to endocrine effects on soil invertebrates. The aims of the present literature study are (1) to compile the existing knowledge of endocrine effects on soil invertebrates via a comprehensive and critical literature review, (2) to identify potentially useful test species and endpoints for evaluating and assessing the effects of endocrine active substances on soil organisms, and (3) to develop recommendations for suitable tests, based on criteria such as sensitivity and practicability. The compiled data set on the effects of potential EDCs on the development and reproduction of soil invertebrates does by far not cover the range of exposed soil organisms or those chemicals that (potentially) act as EDCs. In addition, there is an obvious lack of studies addressing EDC-specific endpoints. The available information on endocrinology of the relevant soil invertebrate groups and on endocrine disruptive effects on these organisms is relatively sparse, and the data are not sufficient to identify critical developmental periods with sufficient certainty. Thus, full life-cycle testing is required to identify potential adverse effects of EDCs on the most relevant groups of soil invertebrates. Actually, we propose to cover the effects of EDCs (and other chronic mode-of-actions (MOA)) in tests with specific endpoints and sufficiently long test durations. However, it is unlikely to start this kind of work with all four groups simultaneously because of limited resources. Acknowledging this it is proposed to start with those tests (species, methods), which scored best in the exercise previously described. Therefore, we propose to develop, validate and standardize life-cycle tests with reproductive endpoints (plus possible additional EDC-specific endpoints. The following four groups of organisms could be exposed and, thus, should be represented in the EDC-specific a test battery:
- life-cycle test with a Collembolan species (hard-body group);
- life-cycle test with an enchytraeid species (soft-body);
- life-cycle test with another arthropod (probably isopod) species (hard body);
- life-cycle test with another oligochaete (probably a lumbricid worm) species (soft-body).
In addition, one further organism group should be mentioned, which has at least a potential to contain test species for EDCs: the nematodes. However, so far, the available information is not sufficient to recommend an EDC-focused test system. Instead, basic research should be perfor-med to better understand the ecological relevance of effects on and the sensitivity of nematodes. With regard to gastropods, the most suitable test species has to be identified before discussing test practicability and sensitivity. In short, both applied and basic research is highly needed. In detail, a step-wise approach is recommended in order to identify the effects of potential EDCs (and substances with other MOAs) on soil invertebrates.

Microalgae as polysaccharides producers – Challenges and recent developments
Marine organisms are one of the most underutilized biological resources. The extreme diversity of microalgae, unicellular photosynthetic organisms that are known to produce large quantities of polysaccharides, makes them very attractive for bioprospecting and potential exploitation as commercial sources of exopolysaccharides. Indeed, exopolysaccharides from microalgae have been poorly studied compared to those from bacteria, fungi, terrestrial plants or macroalgae. A french interdisciplinary research project with approaches of biochemistry, physico-chemistry, process engineering and microbiology was conducted between 2015 and 2021. Its main objective was to increase the level of knowledge about the production of soluble polysaccharides with original structures by microalgae from marine and freshwater environments. It intended to develop the scientific background necessary for the industrial exploitation of these exopolysaccharides as hydrocolloids and/or biological active agents and to evaluate economic and environmental impacts of large-scale production. Correlations between original and published structures of exopolysaccharides and the taxonomic affiliation of microalgae producers have been highlighted for the first time. The implementation of physiological stress strategy led to accumulation of exopolysaccharides during microalgae cultivation. After their depolymerization some polysaccharides have been sucessfully tested as anti-age care and slimming agent. Other ones revealed unusual texturant properties as fluid gel behavior.

PLASTICS ADDITIVES: CONTAMINANTS OF EMERGING CONCERN
Additives are essential components of plastic formulations providing maintenance and/or modification of polymer properties, performance, and durability. With a few exceptions, such additives are not chemically bound to the polymer, being able to migrate towards its surface, then possibly leaching out to the environment where can be persistent and remain biologically active. Some plastic additives remain unregulated, raising greater concern and urging research addressing their presence, fate, and effects.
This presentation provides an overview of the mechanistic uptake/migration of plastics additives, and their potential (eco)toxicological effects. It highlights the most prominent ecological implications of the sorption of this multitude of chemical substances and describes some of the present limitations of the currently available literature. It also presents a prospective outlook for future research on this topic.

Phosphogypsum (PG) is a waste or a by-product? Case of valorization of PG in construction materials
Phosphogypsum is a by-product resulting from the acidic attack of phosphate rock to produce phosphoric acid H3PO4. Huge quantities of phosphogypsum amounting up to 280 million tons are produced each year throughout the world. The Tunisian production rate exceeds 10 million tons per year. Actually, the only means of phosphogypsum management in Tunisia is its storage in dumps due to the heavy metals and radionuclides contents which potentially cause problems to the environment and human health. Different PG recovery processes have been proposed in the literature which can be environmentally safe and economically appealing. Through this work we proposed to address the question on how it can be valorized and whether it can be used in construction. This study, therefore, aimed to upgrade this waste into a value-added by-product.

Smart energy production for brighter tomorrow based on multidisciplinary
The world's energy consumption is on the rise, and it appears that the residential, commercial, transportation, and industrial services industry are the major contributors. Combined with a growing global population, electricity generation worldwide is expected to double by 2050. Multi-directional networks (smart grids) allow the exchange of real-time information between suppliers and users. The global smart grid market was estimated at 37 billion U.S. dollars in 2021. The growth of smart technology is one of the most beneficial trends brought on by advances in material science. Many factors are driving the demand for smart technology. Specifically in the construction sphere, many architects and engineers are looking to integrate data from sensors and intelligent materials to rapidly assess building conditions and identify any issues before they become costly. The quest for effective and sustainable energy use is one of the significant technological challenges today, especially as we find ourselves in the throe of the world’s first real global energy crisis. Even though this is a structural problem, it is vital for individuals, families and businesses to optimize their energy consumption, both to alleviate the astonishing prices and begin a widespread move towards more conscious and responsible energy consumption. In this talk I will present the actual situation of energy production and the recent advances in materials engineering leading to higher H 2 yields, smart windows for heating, solar energy uses and sustainability.

Tsunamis as trans-Mediterranean Sea catastrophic events with damage on the North Africa coastline
The Mediterranean coastal regions experienced several tsunamigenic earthquakes with significant damage. Among the strongest and well known are the Crete in CE 365 (Mw 8.3), Rhodes in 1303 (Mw 8.0), Catania-eastern Sicily (Mw 7.4) in 1693, and the South Aegean Sea (Mw 7.5) in 1956. Severe damage occurred to harbours and cities, and inundations with run-up affected in the past the coastal areas in Egypt, Libya, and Tunisia in particular. Large tsunamigenic earthquakes with Mw ≥ 8 took place along the Hellenic subduction zone. Studies of tsunamigenic deposits were conducted at El Alamein west of Alexandria, and at Henchir El Mejdoul north of Sfax (Tunisia). Sedimentary units made of sand coarse gravel and limestone beach-rock mixed with broken shells of marine gastropods and lamellibranch molluscs, bones and organic matter characterize the catastrophic deposit of tsunami origin. Archaeological sites with walls and broken pottery buried under the same deposits confirm the catastrophic character. Isotopic dating of the catastrophic deposit correlate with the 21 July 365 Crete earthquake. Damage of archaeological sites are reported in Alexandria (Egypt), Sabratha (Libya) and Nabeul (Tunisia). The modelling of a sea wave propagation analogue to that of the CE 365 tsunami in regions with significant increase of coastal constructions (mainly touristic), harbour growths and nowadays dense population in North Africa illustrates the major tsunami risk. The proximity of coastal regions to tsunamigenic earthquake sources calls for the development of tsunami awareness and preparedness with an education programme in North Africa and Mediterranean regions.

Measuring Methane Emissions from Solid Waste Landfills: Side by Side Assessment of Ground-Based, Drone-Based, Satellite-Based Technologies
Anaerobic decomposition in municipal solid waste (MSW) landfills results in the generation and emissions of methane from these facilities. These emissions are a significant source of greenhouse gas emissions at the national and global level. Due to the heterogeneity, the spatial and temporal variability of emissions patterns, it has been very challenging to assign a total GHG emissions contribution of a given landfill. Currently, GHG contributions of each landfill are not based on measurements but estimated based on simplistic and often inaccurate first-order decay models and voluntarily reported to regulatory agencies. Due to the advances in sensor and remote sensing technologies, more and more methods are being developed to measure methane emissions from landfills. Amongst all currently available methods of measuring methane emissions from landfills, the tracer correlation technique is the most accurate method in terms of providing estimates of total methane emissions from landfills. The controlled tracer method is regarded as the benchmark to “ground-truth” any other technologies developed or designed to provide estimates of landfill emissions. The newly formed Methane Emission Reduction Initiative (MERI) at FAMU-FSU College of Engineering, Florida State University has the instrumentations and the capacity to perform the controlled tracer correlation testing. The vision of MERI is to (1) provide scientifically validated methodologies that measures emissions from landfills, and (2) revise and develop protocols for GHG emissions inventories for landfills The presentation will summarize the results of an extensive field campaign consisting of:
- Collecting ambient air methane concentrations measured during (1) SEM campaigns, (2) drone-based air monitoring campaigns, (3) a fixed array of continuous methane concentration sensors, and (4) from controlled tracer experiments at several landfills in the U.S.A.
- Using the collected data from each campaign/technology to determine independent estimates of total methane emissions from each Landfill.
- Verifying and validate the developed approaches by simultaneous tracer correlation method.
- Estimating the difference between measured emissions and regulatory acceptable GHG inventory methods.

REDUCTION IN ECONOMY, ENERGY, ECOLOGY AND ENVIRONMENT IN CONCRETE INDUSTRY USING WASTE MATERIALS
Concrete is a mixture of Portland cement, aggregates, water and admixtures. The principal binder in concrete is Portland cement, the production of which consumes high energy, costly, depletes natural resources and is a major contributor to green-house gases (GHG) emissions that are implicated in global warming and climate change. Every ton of Portland cement production releases about 1 ton of CO2 into the atmosphere. If the world produces 4.1 billion tons of cement per year, it emits approximately the same amount of CO2 in the atmosphere every year, just from one industry. Moreover, concrete consumes more than 8 billion tons of aggregates every year, which also depletes the natural resources, thus causing additional problems to the ecology and the environment. On the other hand, millions of tons of agriculture, industrial and natural waste materials (such as oil and coal burning by-products, fly ash, bottom ash, slag, rice husk ash, palm-oil fuel ash, cement and quarry dust, bagasse, tires, sewer sludge, glass, silica fume, garnets, bentonite, kaolin, volcanic ash, etc.,) are abundantly available in the world and are wasted every year. Most of them may contain one or more of hazardous and toxic chemicals from trace amount to several percentages. The majority of these unused wastes are dumped in landfills, quarries, rivers and oceans, exacerbating environmental concerns like air pollution, leaching into soil and water. Studies have shown that some of these waste materials have been and are being used successfully in all kinds of existing and future concrete structures by replacing cement, sometimes up to 70%. They reduce not only energy, ecology and environmental pollution but also produce stable, more durable and economical sustainable construction materials. This presentation will discuss the issues related to the reduction in economy, energy, ecology and environmental in concrete industry using waste materials.

Ozone inactivation of SARS-COV-2
Ozone is a gas that is easy to produce from either air or pure oxygen using electrical generators. The ozone molecule (O 3 ) has fascinating properties making it an excellent oxidant and disinfectant for an array of applications including water and wastewater treatment, air treatment, agri-food industry, and health. In the recent COVID-19 pandemic, the use of ozone to disinfect surfaces and spaces has even heightened interests in ozone from both industry and the scientific community. Building on the fact that ozone is effective against other viruses, the virucidal properties of ozone against SARS-CoV2 (the virus responsible for COVID-19) has also been established over the past two years. This paper will review the recent research conducted to fight SARS-CoV-2 using ozone in different media including spaces, surfaces, and in droplets. The review will present novel data on the effect of key parameters including ozone dose, exposure time, relative humidity, and virus medium on virus inactivation. This will subsequently lead to a discussion highlighting the optimum conditions for the virus inactivation on surfaces, air and in droplets. Ozone is a toxic gas and should not be breathed.
