“…However, we only considered net buoys, nets, lures, hooks and lines as fisheries related items and placed ropes in a different category. Fishery is not a unique source for ropes, but an important contributor as we observed the highest rope quantities during the main fishing season (43% in autumn; 25% in winter; 19% (Claereboudt, 2004;Edyvane et al, 2004;Otley and Ingham, 2003), and seem to be similar to values worldwide (the share of Ocean/Waterway activities in marine beach litter is 8% globally and 24.9% for Europe; Anonymous, 2010) although fishing efforts are very intense in the study area. We also recorded other probable maritime debris such as oil containers, crates, life-vest fragments and emergency water containers but in very low quantities.…”

“…For example, Ascension Island and the Falkland Islands have no data on their coastal microplastic litter. Data on the abundance and distribution of stranded (Otley and Ingham, 2003) and floating (Barnes and Milner, 2005) macroplastic debris in these areas suggest that, perhaps due to the fragmentation of these larger items, microplastic litter may also be prevalent and therefore it is important to monitor this. In order to quantify the level of under-estimation of microplastic concentrations obtained by current common methods of microplastic sampling in seawater, we compared the abundances of microplastics recorded by three common sampling methods (bongo, manta and plankton nets) with those obtained by of 1 L filtered seawater obtained with bottle grabs.…”

To date there is no gold standard for sampling microplastics. Zooplankton sampling methods, such as plankton and Neuston nets, are commonly used to estimate the concentrations of microplastics in seawater, but their ability to detect microplastics is limited by their mesh size. We compared different net-based sampling methods with different mesh sizes including bongo nets (>500µm), manta nets (>300µm) and plankton nets (>200µm and >400µm) to 1 litre bottle grabbed, filtered (0.45µm) samples. Concentrations of microplastics estimated using net-based methods were ~3 orders of magnitude less than those estimated by 1 litre grab samples. Some parts of the world with low human populations, such as Ascension Island and the Falkland Islands, lack baseline data on microplastics. Using the bottle grab sampling method we found that microplastic litter was present at these remote locations and was comparable to levels of contamination in more populated coastal regions, such as the United Kingdom.

“…The typology of items found in the literature relates the quantity of marine litter to the inadequate handling of solid wastes, which can remain in the environment for long periods and be transported over long distances by winds, rivers and marine currents (Vauk et al, 1987;Silva-Iñiguez et al, 2003). Shipping-related activities (Dixon et al, 1981;Vauk et al, 1987), commercial fishing (Otley et al, 2003;Edyvane et al, 2004) and waterborne sources (Stefatos et al, 1999;Moore et al, 2001) have been reported as the origin of litter. However, in areas with intensive beach usage, there is evidence that direct inputs by beach goers can significantly contribute to a deterioration of the coastal environment (Willoughby, 1986;Velander et al, 1998).…”

, which is comparable to the results of other studies in the Mediterranean. Multivariate analyses (principal component analysis and redundancy analysis) confirmed strong similarities between islands and a statistically significant seasonal evolution of litter composition and abundance. In summer (the high tourist season), debris contamination expressed as item abundance was double that in the low season and showed a heterogeneous nature associated with beach use. Cigarette butts were the most abundant item, accounting for up to 46% of the objects observed in the high tourist season. In contrast, plastics related to personal hygiene/medical items were predominant in wintertime (67%) and natural wood was the most important debris by weight (75%). In both seasons, litter characteristics suggested a strong relationship with local land-based origins. While beach users were the main source of summer debris, low tourist season litter was primarily attributed to drainage and outfall systems.Keywords: Balearic Islands, beach, debris, litter, Mediterranean Sea, tourism. RESUMEN: ORIGEN Y ABUNDANCIA DE RESIDUOS EN PLAYAS DE LAS ISLAS BALEARES. -En un estudio realizado durante el año 2005 se analizó la abundancia, naturaleza y posibles orígenes de los residuos presentes en 32 playas de las Islas Baleares (mar Mediterráneo). La abundancia media de objetos en verano fue de aproximadamente 36 objetos por metro lineal, con un peso correspondiente de 32±25 g por metro lineal, lo cual es comparable a otros estudios en el Mediterráneo. El estudio mediante análisis multivariantes (Análisis de Componentes Principales y Análisis de Redundancia) confirma importantes similitudes entre islas, además de una evolución estacional estadísticamente significante en la composición y abundancia de los residuos. La contaminación durante el verano, expresada en términos de abundancia de objetos en la playa, duplica el valor registrado en invierno. Además, los objetos hallados durante esta época son de naturaleza heterogénea lo que se asocia con los vertidos realizados por los usuarios de las playas. De lo recogido en verano, las colillas son el residuo más abundante, alcanzando un 46% de los objetos observados. Por el contrario, los plásticos, y en particular los relacionados con el aseo personal y las medicinas son el tipo de objeto más común en invierno (67%) y las maderas representan el tipo de residuo más abundante en cuanto a peso (75%). En ambas estaciones, los residuos encontrados muestran una estrecha relación con fuentes de tipo local; mientras que los usuarios de las playas son el mayor foco de residuos en el verano, en invierno éstos se asocian con los sistemas de alcantarillado y emisarios.
