Microplastics: A local action to aware environmental global problems

AI summary Read the abstract

This paper described a local community educational initiative in Spain designed to raise awareness of marine microplastic pollution by engaging citizens in beach monitoring activities. Participants collected and analyzed microplastic samples from local beaches, connecting global environmental problems to visible, local realities. The project demonstrates how citizen engagement in science can both generate useful data and build public understanding of microplastic pollution.

Study Type Environmental

Marine plastic litter is a global problem that affects coastal areas as a result of their low density, which make them easy to spread. Once plastics reach the ocean, they break into smaller particles mainly by photo-oxidation, thermal oxidation and mechanical degradation, among others. In the last years, concern about microplastic contamination (1 μm - 5 mm) has clearly increased at many levels, specially the scientific, which has reported new hotspots of plastic debris [1,2,3]. In primary and secondary education, environmental awareness is included as part of the current the curricula (Ley Orgánica 2/2006, de 3 de mayo, de Educación and Ley 6/2014 de 25 de julio, Canaria de Educación no Universitaria). However, in the curricular specifications, local environmental problems, which are of special concern to identify students awareness, are not frequently included in the textbooks. The general aim of this contribution is to provide specific activities to raise environmental awareness on problems related with the presence of microplastics in the marine environment to non-university students. In particular, we provide a template for counting and separating microplastics as well as to describe the steps to make sensory boxes that allow students to understand the difficulties that marine animals have in discerning between plastics and food. The microplastic template and sensory boxes were tested on 86 students of 14 years old (middle school) and 23 students aged 16 (high school) of Santa Cruz de Tenerife, showing a successful and easy application of a local action to aware environmental global problems.

Citizen Science for Assessment of Microplastics on Beaches: A Case Study in Mexico

AI summary Read the abstract

Researchers used a citizen science approach involving 26 volunteers to assess microplastic abundance and type on Mexican beaches, providing broad geographic coverage at lower cost than traditional monitoring. Participants used standardized materials and training to collect and identify microplastics, generating a representative database that also raised public awareness of coastal plastic pollution.

Microplastic Pollution in the Coast of Tarragona

AI summary Read the abstract

Students and educators in Tarragona, Spain conducted a citizen science study measuring microplastic concentrations in coastal seawater and beach sand. The study found microplastics at all sampling sites, demonstrating that even relatively less industrialized Mediterranean coastal areas face significant microplastic pollution.
