“…Authors concluded that additional research on the use of chemotherapeutic agents is required given the lack of data on currently used compounds and to clarify transformation and biodegradation processes (Lorenzo et al., ). In the aquaculture industry, chemotherapeutants such as organophosphates, carbamates, and pyrethroids pesticides are used to control pests meaning their residues can be found in the marine environment (García‐Rodríguez et al., ; García‐Rodríguez, Carro‐Díaz, Lorenzo‐Ferreira, & Cela‐Torrijos, ). For instance, given the hydrophobicity and persistence of organochlorine pesticides (such as dichlorodiphenyltrichloroethane [DDT] and its metabolites) they tend to associate to particulate matter such as seaweed, thereby bioaccumulating in the food chain and potentially affecting human health through exposure to contaminated foods (García‐Rodríguez et al., ; Lorenzo et al., ; Moreno, Ferrera, & Rodríguez, ).…”

Seaweed is a source of protein that can help overcome the anticipated challenges of a growing world population and the current challenges for finding alternatives for animal proteins in the Western diet. Thus far, data on the safety of seaweed for feed and food purposes in the Western world are scattered. This study aimed to review the available knowledge on the presence of food safety hazards in seaweed, including factors influencing their presence, and to prioritize the hazards that may pose a risk to human health. Given current knowledge from the literature, data from the Rapid Alert System for Food and Feed, and results from a stakeholder survey, 22 food safety hazards were ranked into major (4), moderate (5), and minor (13) hazards. Arsenic, cadmium, iodine, and Salmonella were identified as major hazards. Hazards, where data gaps exist, should be carefully assessed. These include pesticide residues, dioxins and polychlorinated biphenyls, brominated flame retardants, polycyclic aromatic hydrocarbons, pharmaceuticals, marine biotoxins, allergens, micro‐ and nanoplastics, other pathogenic bacteria, norovirus, and hepatitis E virus. It is recommended to collect more data on these hazards in future studies. Many factors can affect the presence of hazards including seaweed type, physiology, season, harvest and cultivation environment, geography including the location of cultivation, alongside further processing. Moreover, when seaweed is cultivated near industrialized or anthropogenic activities, these activities may negatively influence water quality, which can increase the likelihood of hazards in seaweed. Results of the ranking prioritized hazards can be used to prioritize monitoring programs and adjusted given future additional knowledge covering the data gaps.

“…ESI in positive-ion mode (compounds ionized by adding a proton) was selected as the ionization technique owing to its sensitivity, ruggedness and easy handling and maintenance for all analytes, except for the benzoylurea family, whose separation and determination were studied in negative-ion mode (losing a proton), which has better specificity and sensitivity [21,29]. The optimization of the ionization was performed by a series of preliminary experiments, testing different modifiers in a binary gradient mobile phase comprising ACN and water, such as acetic acid and ammonium acetate at various concentrations.…”

“…Previous studies suggest that ACN with a low percentage of acetic acid [21,27,28] and MeOH [32] are generally the preferred solvents for avermectins. On the other hand, a mixture of hexane and ethyl acetate (4:1) has been shown to be useful for carbamates and organophosphorus compounds [14,29]. For benzoylureas, extraction was achieved with aqueous mixtures with MeOH [33].…”

Chemical residues, such as insecticides and anthelmintics, are frequently redistributed from the aquatic environment to marine species. This work reports on a fast validated protocol for the analysis of azamethiphos, three avermectins, two carbamates and two benzoylurea pesticides and chemotherapeutic agents in seaweeds based on pressurized liquid extraction and separation of analytes by liquid chromatography coupled with tandem mass spectrometry. The variables affecting the efficiency of pressurized liquid extraction, including temperature, number of extraction cycles, static extraction time and percent acetonitrile flush volume, were studied using a Doehlert design. The optimum parameters were 100 °C and one cycle of 3 min with 70 % acetonitrile. Adequate in-cell clean-up of the seaweeds was achieved using 0.8 g of Florisil over 0.1 g of graphitized carbon black on the bottom of the cell. The optimized method was validated using an analyte-free seaweed sample fortified at different concentrations. The limits of quantification ranged from 3.6 μg kg(-1) (azamethiphos) to 31.5 μg kg(-1) (abamectin). The recovery was from 87 to 120 % in most cases at different spiking levels. Finally, the reproducibility of the method expressed as the relative standard deviation and evaluated at concentrations of 10 and 50 μg kg(-1) was in the range 9-14.3 % and 6.1-12.3 %, respectively. The applicability of the method was evaluated with five commercial and 12 wild edible seaweeds, and four target compounds were detected in two wild seaweeds at a concentration below the quantification limit.
