“…In this case, mudskippers (here representing the fish category) can accumulate contaminants via two different routes: bioconcentration (dermal absorption of contaminants) and bioaccumulation (assimilation of contaminants by food intake) (Ansari et al 2014). A similar pattern was also observed and highlighted in our previous work (Ivorra et al 2021), which can explain the high levels quantified in these organisms when compared to the other categories. This was also explored by Fan et al (2019) when quantifying several endocrine disruptors in fish with different feeding habits.…”

“…Surprisingly, DDTs were quantified at higher concentrations in this study than in previous monitoring reports Lam 2004, Wong et al 2005). For example, mudskippers (B. pectinirostris and B. boddarti) collected from Mai Po areas in Hong Kong, presented 13-and twofold lower than the values quantified in the present work, suggesting that DDT pollution in the south China area is still a current concern (Guo et al 2009;Ivorra et al 2021).…”

The extraction of 21 insecticides and 5 metabolites was performed using an optimized and validated QuEChERS protocol that was further used for the quantification (GC–MS/MS) in several seafood matrices (crustaceans, bivalves, and fish-mudskippers). Seven species, acquired from Hong Kong and Macao wet markets (a region so far poorly monitored), were selected based on their commercial importance in the Indo-Pacific region, market abundance, and affordable price. Among them, mussels from Hong Kong, together with mudskippers from Macao, presented the highest insecticide concentrations (median values of 30.33 and 23.90 ng/g WW, respectively). Residual levels of fenobucarb, DDTs, HCHs, and heptachlors were above the established threshold (10 ng/g WW) for human consumption according to the European and Chinese legislations: for example, in fish-mudskippers, DDTs, fenobucarb, and heptachlors (5-, 20- and tenfold, respectively), and in bivalves, HCHs (fourfold) had higher levels than the threshold. Risk assessment revealed potential human health effects (e.g., neurotoxicity), especially through fish and bivalve consumption (non-carcinogenic risk; ΣHQLT > 1), and a potential concern of lifetime cancer risk development through the consumption of fish, bivalves, and crustaceans collected from these markets (carcinogenic risk; ΣTCR > 10–4). Since these results indicate polluted regions, where the seafood is collected/produced, a strict monitoring framework should be implemented in those areas to improve food quality and safety of seafood products.

“…Although the benefits are not obvious to the local population as they are not reliant on fisheries or harvests directly taken from the mangroves, there are many ecosystem services that mangroves provide to the city and its people. The forest cover is small (approximately 19 ha in 2020), but mangroves in Macao significantly contribute to local biodiversity and provide other important ecosystem services as they serve as coastal nursery habitats for fishes and other marine life, contribute to carbon sequestration and storage, filter and improve water quality, act as a buffer zone between land and sea, and provide sites for ecotourism and education [ 37 , 38 ]. However, the challenge is how to promote this idea to the local community to create an impact and foster more conservation efforts.…”

Mangrove forests are one of the most ecologically valuable ecosystems in the world and provide a wide variety of ecosystem services to coastal communities, including cities. Macao, a highly urbanized coastal city located on the southern coast of China west of the Pearl River, is home to several species of mangroves with many associated flora and fauna. Mangrove forests in Macao are vulnerable to threats due to pressure from rapid and massive urban developments in the area, which led to mangrove loss in the past decades. To address this issue, the local authorities established special Ecological Zones for the management of the local mangroves. To reinforce local conservation efforts, educating the local population about the value of mangroves, especially school students, is of utmost importance. To evaluate the impact of environmental education activities on the environmental orientation, knowledge, and values of students toward mangrove conservation in Macao, a quasi-experimental study was undertaken. The effectiveness of a mangroves exhibition and field visit were evaluated using the New Environmental Paradigm (NEP) Scale—Macao version in a group of local school students who participated in the activities. Overall, the results provided consistently positive evaluations of the impact of the environmental education program. The strongest improvements were found in the students’ pro-environmental orientations, knowledge about mangroves, and value for environmental protection.

“…Cependant, les processus de rétention ou de dégradation sont souvent difficiles à mettre en évidence à cause d'un effet de dilution très marqué par la présence d'un grand volume dans l'étang (Le Cor et al, 2021). Les mangroves (écosystèmes côtiers en interface entre le continent et les océans) fournissent des conditions de remédiation via le prélèvement des PPP par la végétation, l'accumulation, la détoxication, la rétention et la dégradation (Ivorra et al, 2021). Par ailleurs, les conditions hydrologiques sont favorables à l'expression de ces processus en augmentant la sédimentation et en ralentissant les écoulements.…”

Dans le cadre du Plan Ecophyto II + , différents travaux d'expertise sont conduits de manière complémentaire. L'Inserm a présenté en juin 2021 les résultats d'une expertise collective dont il avait été saisi sur les effets des produits phytopharmaceutiques sur la santé humaine intitulée Pesticides et santé -Nouvelles données. La présente expertise scientifique collective est quant à elle centrée sur les impacts de ces produits sur la biodiversité et les services écosystémiques. Une autre expertise scientifique collective restituée à l'automne 2022 porte sur la gestion des couverts végétaux pour réguler les bioagresseurs des cultures.Commandée en mars 2020 par les ministères en charge de l'Environnement, de l'Agriculture, et de la Recherche, la présente expertise a été confiée à INRAE et à l'Ifremer. Elle actualise et complète les travaux antérieurs qui avaient été restitués en 2005 sur Pesticides, agriculture et environnement, et en 2008 sur Agriculture et biodiversité.Les résultats sont publiés sur les sites internet d'INRAE et de l'Ifremer sous trois formats. Le rapport comporte un rappel des éléments de contexte de l'expertise, la description de la méthode mise en oeuvre et de l'ensemble de la bibliographie qui intègre plus de 4 000 références, les éléments de cadrage scientifique de l'Expertise scientifique collective (ESCo), l'ensemble des analyses produites par les experts de l'ESCo, ainsi que les conclusions générales qui en découlent. La présente synthèse rassemble les principaux constats établis dans le rapport d'ESCo, sans mobiliser l'intégralité du corpus bibliographique utilisé. Les références ne sont citées dans ce document que lorsque les données ou exemples mentionnés sont directement issus d'une publication. Le résumé en 10 pages présente les principaux enseignements tirés de ces travaux.
