Microplastic accumulation dynamics in two Mediterranean beaches with contrasting inputs
نویسندگان
چکیده
Plastic debris is becoming a growing environmental concern and microplastics (size <5 mm) are one of the most important fractions due to their human potential deleterious effects. Despite recent effort done on estimating concentrations in several ecosystems, dynamics microplastic accumulation not sufficiently studied. In this work, short-and long-term have been studied two beaches located Western Mediterranean with low high anthropogenic pressure by sampling twice per week surface sediment for month, in-depth, respectively. As regards short-term dynamics, no clear correlation was detected between levels oceanographic variables. both beaches, fibres were predominant shape pattern along depth observed. Only at beach pressure, there 125 μm fraction sediment. The obtained results suggest that, areas where direct sources pollution, can be driven variables greater extent than microplastics. present study suggests that difficult monitored dynamism. Additionally, special care needs taken when studying since greatly affect accumulation. • Microplastics distribution buried sediments still little understood. Fibres common type southeast coast Spain. abundance has positively correlated sand fraction.

Contrasting Biogeographic and Diversification Patterns in Two Mediterranean-Type Ecosystems
The five Mediterranean regions of the world comprise almost 50,000 plant species (ca 20% of the known vascular plants) despite accounting for less than 5% of the world's land surface. The ecology and evolutionary history of two of these regions, the Cape Floristic Region and the Mediterranean Basin, have been extensively investigated, but there have been few studies aimed at understanding the h...
متن کاملNeustonic microplastic and zooplankton in the North Western Mediterranean Sea.
Neustonic microplastic and zooplankton abundance was determined in the North Western Mediterranean Sea during a summer cruise between July 9th and August 6th 2010, with a break between July 22 th and 25th due to a strong wind event. Ninety percent of the 40 stations contained microplastic particles (size 0.3-5mm) of various compositions: e.g., filaments, polystyrene, thin plastic films. An aver...

Leaf physiological traits and its relation with sugar beet cultivar success in two contrasting environments
The aim of this study was to identify leaf physiological traits, which could be used in selecting high yielding genotypes among 12 sugar beet cultivars grown in two contrasting pedo-climatic environments. In the stressful Site 1 (high temperatures, low rainfall, heavy-textured soil), high yielders had cooler leaves (lower ΔT) and thus, transpired (E) and photosynthesized (A) more. Also, these c...
متن کاملAccumulation of microplastic on shorelines woldwide: sources and sinks.
Plastic debris <1 mm (defined here as microplastic) is accumulating in marine habitats. Ingestion of microplastic provides a potential pathway for the transfer of pollutants, monomers, and plastic-additives to organisms with uncertain consequences for their health. Here, we show that microplastic contaminates the shorelines at 18 sites worldwide representing six continents from the poles to the...
