Seafood covering fish, crustaceans, molluscs and cephalopods is broadly recognised for its nutritional value popularity, but it can pose some hazards to health the potential consumer. The aim of study was analyse Rapid Alert System Food Feed (RASFF) notifications seafood over period 1996–2020 by hazard, year, product, notifying country, country origin, notification type, basis, distribution status action taken. research applied cluster analysis using joining two-way methods. main reported were micro-organisms (Listeria, Salmonella, Escherichia coli, Vibrio, norovirus, mesophiles, Enterobacteriaceae histamine), heavy metals (mercury cadmium), veterinary products (nitrofuran, chloramphenicol leucomalachite green), controls (poor temperature control hygienic state), parasites (Anisakis) additives/allergens (sulphite). originated mainly from European Asian countries notified on basis official or border controls, respectively. In order minimize eliminate risks, important have right activity authorities, appropriate legislation at national levels awareness different stages food chain.

Coastal Bathing Water Quality in Portugal and Poland: Students’ Perspectives of Its Importance

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 174 - 174

Published: Jan. 10, 2025

Coastal bathing waters are leading tourist destinations, mainly during holiday periods. Therefore, the quality of is key importance to tourists. In 2006, European Union (EU) adopted Bathing Water Directive (BWD). EU Member States required analyze status their waters, which determined by presence or absence microbial contaminants (Escherichia coli and enterococci). This study presents coastal in Portugal Poland 3-year period from 2020 2022. The difference water two countries—excellent versus worse Poland—is caused contrasting management sampling practices differing geographical environmental conditions (in Portugal, warm, open sea, Poland, a temperate, semi-enclosed sea that almost surrounded land exposed urban wastewater discharge). Additionally, results questionnaire showed ecological awareness responses well developed Portuguese Polish students regardless different waters. To best authors’ knowledge, this among first relationships between pollution students’ opinions on tourism. provide valuable information policymakers, entities, educational institutions can use develop more efficient strategies for both countries.

Coastal zones vulnerability evaluation in the southern Baltic Sea: Shoreline dynamics and land use/land cover changes over five decades

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 976, P. 179345 - 179345

Published: April 8, 2025

Over the past century, coastal zones have experienced significant population growth and rapid development, often conflicting with these environments' dynamic sensitive nature. The present study investigated five decades (1972-2023) of shoreline dynamics land-use/land-cover (LULC) transformations along three sectors located on a 47 km stretch Southern Baltic coastline. research employed eleven multispectral Landsat MSS/TM/OLI images within geographic information system (GIS) framework to analyze coastline variations LULC patterns. Results showed accretion in Sector I (Usedom), while Sectors II III (Wolin) marked erosion. entire period, 29.59 % (3.21 km), 39.90 (4.51 67.54 (9.45 km) shorelines Sector-I, Sector-II, Sector-III distance correlation that hydrometeorological variables associated wind-wave dynamics, exerted stronger influence changes. change analysis highlighted decline forest cover (-846.86 ha) increased built-up areas (+1137.86) across all sectors. These results enabled identification four vulnerability zones-one Usedom Wolin-characterized by pronounced erosion, degradation, urban expansion. findings can inform management strategies identifying high-risk zones, guiding sustainable development practices, prioritizing for conservation intervention.

Long-Term Heavy Metal Bioaccumulation in Sprat (Sprattus sprattus) from the Romanian Black Sea: Ecological and Human Health Risks in the Context of Sustainable Fisheries

Fishes, Journal Year: 2025, Volume and Issue: 10(4), P. 178 - 178

Published: April 15, 2025

This study evaluates the heavy metals concentrations in sprat (Sprattus sprattus, Linnaeus, 1758) from Romanian Black Sea, assessing both ecological implications and human health risks associated with consumption. Using long-term data spanning 1994–2019, levels of copper (Cu), cadmium (Cd), lead (Pb), nickel (Ni), chromium (Cr) dorsal muscle tissues were analyzed to identify contamination trends episodic pollution events. Although most remained below regulatory thresholds, occasional exceedances Cd Pb suggest intermittent inputs. Health assessed using dietary indices including estimated daily intake (EDI), target hazard quotient (THQ), total (TTHQ), carcinogenic risk index (CRI). Findings indicate that, under current exposure levels, regular consumption poses minimal risk. However, prolonged during peak periods may contribute cumulative toxic effects, for ecosystem stability food safety. Given persistence their interactions co-occurring pollutants, such as persistent organic pollutants (POPs) polycyclic aromatic hydrocarbons (PAHs), ongoing monitoring remains essential. supports development sustainable environmental policies aimed at protecting marine biodiversity consumer Sea region.
