Environmental contaminants of emerging concern in seafood - European database on contaminant levels
2015 •
helena lourenço
Marine pollution gives rise to concern not only about the environment itself but also about the impact on food safety and consequently on public health. European authorities and consumers have therefore become increasingly worried about the transfer of contaminants from the marine environment to seafood. So-called "contaminants of emerging concern" are chemical substances for which no maximum levels have been laid down in EU legislation, or substances for which maximum levels have been provided but which require revision. Adequate information on their presence in seafood is often lacking and thus potential risks cannot be excluded. Assessment of food safety issues related to these contaminants has thus become urgent and imperative. A database (www.ecsafeseafooddbase.eu), containing available information on the levels of contaminants of emerging concern in seafood and providing the most recent data to scientists and regulatory authorities, was developed. The present paper r...
Microplastic in the Environment: Pattern and Process
Dietary Exposure to Additives and Sorbed Contaminants from Ingested Microplastic Particles Through the Consumption of Fisheries and Aquaculture Products
2021 •
Violetta Costanzo
Microplastics and nanoplastics may be found in the gastrointestinal tract of some aquatic animals and could potentially be ingested by humans if consumed whole. Information on the toxicity of plastic particles, as well as co-contaminants such as plastic additives, remains scarce. This represents a serious challenge to perform realistic risk assessments. An exposure assessment of selected plastic additives and co-contaminants of known toxicity associated with microplastics was carried out for shellfish in this study, which builds on an exposure assessment of microplastic additives and a limited number of associated contaminants in mussels conducted by the FAO in 2017. This study evaluates possible impacts to food safety by examining a diverse additives and associated sorbed contaminants. The results suggest that the levels of certain microplastic additives and sorbed co-contaminants in target animals (shrimp, prawns, clams, oysters, and mussels) do not pose a food safety threat to co...

Potential Risk of Organic Contaminants to The Coastal Population Through Seafood Consumption from Jakarta Bay
2018 •
Hari Eko Irianto
A comprehensive study on exposure assessment of the priority organic contaminants via seafood consumption has been conducted to the coastal population of Jakarta Bay. Seafood is essential food source in Indonesia and also important income for the majority of coastal populations. A number of 152 respondents from 4 districts surounding the bay were interviewed to record their frequency and pattern on seafood consumption. In the same time, 13 seafood species were collected directly from Jakarta Bay during the dry and wet seasons for the assessment of organic contaminants. A non-target GC/MS screening identified more than 40 organic contaminants in which 6 of them are potentially considered as priority contaminants including 3 groups of carcinogenic contaminants i.e. dichlorodiphenyl-trichlorethane (DDT) and its metabolites (DDXs), dichlorobenzenes (DCB) and carcinogenic PAHs (PAH4). Further exposure analysis suggested cumulative health risk of these contaminants was less than official ...

Environmental Chemical Contaminants in Food: Review of a Global Problem
Wageh Sobhy Darwish
Contamination by chemicals from the environment is a major global food safety issue, posing a serious threat to human health. These chemicals belong to many groups, including metals/metalloids, polycyclic aromatic hydrocarbons (PAHs), persistent organic pollutants (POPs), perfluorinated compounds (PFCs), pharmaceutical and personal care products (PPCPs), radioactive elements, electronic waste, plastics, and nanoparticles. Some of these occur naturally in the environment, whilst others are produced from anthropogenic sources. They may contaminate our food—crops, livestock, and seafood—and drinking water and exert adverse effects on our health. It is important to perform assessments of the associated potential risks. Monitoring contamination levels, enactment of control measures including remediation, and consideration of sociopolitical implications are vital to provide safer food globally.

Erythrosine B in the Environment. Removal Processes
2016 •
Laura Apostol
This paper presents a comparison of the results obtained for different methods used for the decolorization of the food dye Erythrosine B. Erythrosine B is a red odorless powder used in food industry as a colloring substance. Erythrosine B, also known as E 127, consists essentially of disodium 2-(2,4,5,7-tetraiodo-6-oxido-3-oxoxanthen-9-yl) benzoate monohydrate and subsidiary coloring matters together with water, sodium chloride and sodium sulphate as the principal uncolored components. The methods considered in this paper were sorption, biodegradation and photodegradation. Sorption demonstrated good removal efficiency in the presence of low-cost activated carbon from agro-waste but the treatment increases the operation cost. Because of Erythrosine B toxicity aerobic biodegradation processes showed to be inefficient in the most studies. Considering this, Erythrosine B degradation could be performed by photodegradation process using an adequate c...
Microplastics in fisheries and aquaculture Status of knowledge on their occurrence and implications for aquatic organisms and food safety
Antonio Martín Low Pfeng
Microplastics in fisheries and aquaculture: status of knowledge on their occurrence and implications for aquatic organisms and food safety FAO This report looks into the issue of microplastics from the fisheries and aquaculture perspective. Based on existing scientific literature, a group of experts assessed the potential impact of microplastics and related contaminants on fish consumers' health and the ecological implications for aquatic organisms. A workshop was organized with invited experts (Rome, 5-8 December 2016) who complemented the published information and carried out a risk profiling of microplastics in aquaculture and fishery products. Despite the large amount of scientific data available, there are still significant knowledge gaps, in particular regarding impacts at fish population and community level, detailed data for a proper risk assessment and implications of nanoplastics presence in the marine environment. Nonetheless, measures should be taken at international, governmental and consumer levels to undertake cost-effective ecological and seafood safety risk assessments on micro-and nanoplastics and associated polymers, to reduce plastic use and encourage the use of alternative materials, recycling and the adoption of sustainable practices in using plastics and managing plastic pollution.

Non-Target Screening Method for the Identification of Persistent and Emerging Organic Contaminants in Seafood and Sediment from Jakarta Bay
2015 •
Hari Eko Irianto
Identification of persistent and emerging organic contaminants in green mussels (Perna viridis), various fishes, banana shrimp (Penaeus merguiensis) and sediment samples from Jakarta Bay has been employed. A non-target GC-MS screening approach has identified more than 60 individual organic compounds from the whole fractions either non-polar, semi-polar or acidic-polar compounds. The substances comprised as persistent organic pollutants (POPs) including DDT (dichlorodiphenyl trichloroethane) and its metabolites as well as high molecular weight polycyclic aromatic hydrocarbons (HMW-PAHs). Noteworthy, a number of emerging contaminants detected in the present study have never been reported previously either from the same location or from Asian waters. They include some priority contaminants of non-persistence halogens and emission of technical products, such as di-iso-propylnaphthalenes (DIPNs) dichlorobenzene (DCB), dichlorodiphenyl chloroethene (DDMU) and phenylmethoxynaphthalene (PMN...
