A current overview of the pharmacological composition of "La Chimique" consumed in Mayotte: Preliminary results of the CHASSE-MAREE protocol.

Mayotte Island, a French department located in the Mozambique Channel, has for several years been faced with the consumption of "La Chimique" (LC), reputed (but extremely poorly documented) to be a mixture of tobacco and synthetic cannabinoid receptor agonists (SCRAs). One of the objectives of the CHASSE-MAREE protocol is to assess the composition and heterogeneity of LC products through successive LC sample collection campaigns among users. Currently underway, we present here the first analytical results (samples collected in 2022).

Arsenic in Caribbean bivalves in the context of Sargassum beachings: A new risk for seafood consumers.

Sargassum strandings in the coastal environment can introduce arsenic into food webs. In this context, we assessed the risk of exposure to arsenic for consumers of Caribbean bivalves. In 2019, specimens of Asaphis deflorata and Phacoides pectinatus were collected in an Atlantic coastal zone of Martinique (island) to monitor the presence of arsenic species by LC-ICP-MS.

Micropollutant content of Sargassum drifted ashore: arsenic and chlordecone threat assessment and management recommendations for the Caribbean.

Massive Sargassum beachings occurred since 2011 on Caribbean shores. Sargassum inundation events currently involve two species, namely S. fluitans and S.

Quantifiable urine glyphosate levels detected in 99% of the French population, with higher values in men, in younger people, and in farmers.

France is the first pesticide-consuming country in Europe. Glyphosate is the most used pesticide worldwide and glyphosate is detected in the general population of industrialized countries, with higher levels found in farmers and children. Little data was available concerning exposure in France.

Differentially Shapes the Microbiota Composition and Diversity at Coastal Tide Sites and Inland Storage Sites on Caribbean Islands.

Rafts of drifting pelagic that are circulating across the Atlantic Ocean are complex ecosystems composed of a large number of associated species. Upon massive stranding, they lead to various socio-environmental issues including the inflow of contaminants and human health concerns. In this study, we used metabarcoding approaches to examine the differences in both the eukaryotic- and prokaryotic-associated communities from present in two islands of the Lesser Antilles, namely Guadeloupe and Martinique.

Removal efficiency of emerging micropollutants in biofilter wastewater treatment plants in tropical areas.

We studied the removal of 61 emerging micropollutants, including illicit drugs, in a biofilter wastewater treatment plant located in the French Indies (Martinique). Raw wastewater concentrations were the highest for paracetamol followed by caffeine, naproxen, ibuprofen, its metabolite 2-hydroxyibuprofen, atenolol, ketoprofen, furosemide, methylparaben, cocaine, benzoylecgonine, and 11-nor-delta-9-carboxytetrahydrocannabinol (THC-COOH). The calculated removals were better than those reported in the literature, while the cumulative removal efficacy (i.

Reprint of: The effect of the Music Day event on community drug use.

Illicit drugs consumption can be back-calculated based on the analysis of drug residues in wastewater using the wastewater-based epidemiology method. The Music Day, held on June 21 in France since 1982, has grown to global proportions and is now celebrated as World Music Day. This large outdoor event takes place in many cities with people allowed to play music in the streets.

Wastewater-based epidemiology approach to assess population exposure to pesticides: a review of a pesticide pharmacokinetic dataset.

Wastewater-based epidemiology is an innovative approach to estimate a population's intentional and unintentional consumption of chemicals based on biomarker assays found in wastewater. This method can provide real-time objective information on the xenobiotics to which a population is directly or indirectly exposed. This approach has already been used to assess the population exposure to four classes of pesticides: organochlorines (chlordecone), triazines, organophosphates, and pyrethroids.

Prosulfocarb at center stage!

Prosulfocarb is a thiocarbamate herbicide that is rapidly growing in use due to the progressive bioresistance of weeds to certain pesticides and the ban and/or limitation of others. However, the use of prosulfocarb is only recent, and the relevant literature is scarce. The environmental and food impact of prosulfocarb has already been observed, and its transfer mode from targeted crops to untargeted parcels has been investigated.

Spatio-temporal assessment of illicit drug use at large scale: evidence from 7 years of international wastewater monitoring.

Background And Aims: Wastewater-based epidemiology is an additional indicator of drug use that is gaining reliability to complement the current established panel of indicators. The aims of this study were to: (i) assess spatial and temporal trends of population-normalized mass loads of benzoylecgonine, amphetamine, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA) in raw wastewater over 7 years (2011-17); (ii) address overall drug use by estimating the average number of combined doses consumed per day in each city; and (iii) compare these with existing prevalence and seizure data.

Design: Analysis of daily raw wastewater composite samples collected over 1 week per year from 2011 to 2017.

Environmental fate of chlordecone in coastal habitats: recent studies conducted in Guadeloupe and Martinique (Lesser Antilles).

The organochlorine pollution by chlordecone, an insecticide spread in the past in banana plantations, is now recognized as a major ecological, economic, and social crisis in Guadeloupe and Martinique Islands. Due to its physical and chemical properties, this molecule is particularly persistent in the natural environment. Volcanic soil of Guadeloupe and Martinique contain allophanes (amorphous clays), which favor chlordecone trapping due to their structure and physical properties.

Chlordecone consumption estimated by sewage epidemiology approach for health policy assessment.

Chlordecone is an organochlorine insecticide that was intensively used in the French West Indies to control the black weevil Cosmopolites sordidus in bananas. Its usage, however, resulted in the widespread pollution of the environment with heavy sanitary and social consequences, leading to population exposure mainly through food. Time-consuming and costly programs have been used to tackle this problem, and this study proposes to use the emerging sewage epidemiology approach to evaluate the current situation and the effect of such programs.

Wastewater-based epidemiology in low Human Development Index states: bias in consumption monitoring of illicit drugs.

Wastewater-based epidemiology is a promising approach worldwide, and its application is currently being developed in non-advanced economies. This technology, based on known toxicokinetic data initially used to detect illicit drugs in well-managed and maintained local sewer networks, has been extended to assess other products such as pesticides, alcohol, flame retardants, nicotine, and other substances. This technology is also used in countries with non-advanced economies.

Exposure of an urban population to pesticides assessed by wastewater-based epidemiology in a Caribbean island.

Wastewater-based epidemiology is an innovative approach to estimate the consumption of chemicals and their exposure patterns in a population, on the basis of measurements of biomarkers in wastewater. This method can provide objective real-time information on xenobiotics directly or indirectly ingested by a population. This approach was used to examine the exposure of the Martinique population to the three classes of pesticides: triazines, organophosphates and pyrethroids.

Analysis of the environmental issues concerning the deployment of an OTEC power plant in Martinique.

Ocean thermal energy conversion (OTEC) is a form of power generation, which exploits the temperature difference between warm surface seawater and cold deep seawater. Suitable conditions for OTEC occur in deep warm seas, especially the Caribbean, the Red Sea and parts of the Indo-Pacific Ocean. The continuous power provided by this renewable power source makes a useful contribution to a renewable energy mix because of the intermittence of the other major renewable power sources, i.

Applying sewage epidemiology approach to estimate illicit drug consumption in a tropical context: Bias related to sewage temperature and pH.

Illicit drug consumption can be estimated from drug target residue (DTR) in wastewater, with the reliability of results being partly linked to DTR stability in the sewage network. However, wastewater temperature and pH drive the stability of molecules and, in this context, tropical conditions must be studied to specify the impact of residence time in the sewage network on DTR degradation. Warmth enhances biotic and abiotic processes such as degradation, leading to a decrease in oxygen content, and consequently, early diagenesis conditions in wastewater.

Ship breaking or scuttling? A review of environmental, economic and forensic issues for decision support.

In a globalized world, the world trade fleet plays a pivotal role in limiting transport costs. But, the management of obsolete ships is an acute problem, with most Ship Recycling Facilities (SRF) situated in developing countries. They are renowned for their controversial work and safety conditions and their environmental impact.

The removal of illicit drugs and morphine in two waste water treatment plants (WWTPs) under tropical conditions.

The consumption of drugs of abuse has been recently investigated in Martinique using the back-calculation approach, also called the "sewage epidemiology" method. Results demonstrated a very high consumption considering the international data. Wastewater treatment plants (WWTPs) are located just behind the Martinique island shoreline, and effluents could impact the vulnerable corals and marine seagrass ecosystem.
