Plastic pollution is considered one of today's major environmental problems. Current land-based monitoring programs typically rely on beach litter data and seldom include plastic pollution further inland. We initiated a citizen science project known as the Mass Experiment inviting schools throughout The Danish Realm (Denmark, Greenland and the Faeroe Islands) to collect litter samples of and document plastic pollution in 8 different nature types. In total approximately 57,000 students (6-19 years) collected 374,082 plastic items in 94 out of 98 Danish municipalities over three weeks during fall 2019. The Mass Experiment was the first scientific survey of plastic litter to cover an entire country. Here we show how citizen science, conducted by students, can be used to fill important knowledge gaps in plastic pollution research, increase public awareness, establish large scale clean-up activities and subsequently provide information to political decision-makers aiming for a more sustainable future.

Human activity has led to the increment of diverse pollutants. Plastics have great practical value since they are present in everyday products. However, not only plastics have gained importance, but their plasticizers such as bisphenol A (BPA), phthalates and other chemicals such as the polyaromatic hydrocarbon compounds (PAHs) have described to impact in human and animal health because of its chronic exposure and that they are endocrine disruptors (EDs).

Dimethyl phthalate (DMP) is widely used as a plasticizer in the plastics industry, posing a serious threat to environmental pollution and public health. In this work, CuFeO@AC was used as a coating to prepare a novel solid-phase microextraction (SPME) fiber. CuFeO@AC fiber exhibits a larger specific surface area and more active sites, significantly enhancing DMP enrichment efficiency.

This study presents the first integrated assessment of plastic pollution at the Kura River delta, where the river enters the hydrologically enclosed Caspian Sea. We applied a modular toolbox comprising four complementary components: high-resolution hydrodynamic modeling to predict debris convergence zones, UAV-based mapping to survey shoreline conditions, automated object-based image analysis for debris detection and classification, and standardized field monitoring by trained community participants for ground-truthing and source identification. Using this framework, we identified debris accumulation hotspots and developed a replicable approach for assessing plastic pollution in semi-enclosed systems.

Marine ecosystems are increasingly threatened by anthropogenic pollutants, including plastics, persistent organic pollutants, heavy metals, oil, and emerging contaminants. This meta-analysis examined the accumulation patterns of five major contaminants-mercury (Hg), polychlorinated biphenyls (PCBs), microplastics, per- and polyfluoroalkyl substances (PFAS), and polycyclic aromatic hydrocarbons (PAHs)-in relation to trophic level and lifespan across marine species. Data synthesis revealed distinct differences in bioaccumulation and biomagnification between legacy and emerging contaminants.

Introduction: The increasing use of biodegradable plastics has led to the inevitable human consumption of biodegradable microplastics (MPs). These MPs can be degraded and absorbed into various organs and tissues via the gastrointestinal tract, with the liver being the primary target for digestion and absorption.
Objectives: This study aimed to investigate the toxic effects and mechanisms of biodegradable MPs on the liver following gastrointestinal degradation.
