Thermal analysis and enhanced visual technique for assessment of microplastics in fish from an Urban Harbor, Mediterranean Coast of Egypt
AI summary Read the abstract
Researchers applied an enhanced visual counting technique combined with combustion analysis and differential scanning calorimetry to assess microplastics in fish digestive tracts from Alexandria's Eastern Harbor, Egypt, detecting seven thermoplastic polymer types in all fish samples in what was the first such quantification study in Egypt.
Enhanced visual counting technique coupled with combustion analysis and differential scanning calorimetry (DSC) was applied to assess microplastics (MPs) contamination in fish digestive tracts from Eastern Harbor, Egypt, to provide a simple and economic method for MPs assessment. This was the first study in Egypt to quantify MPs in fish. Plastic particles were detected in all fish samples, represented by seven thermoplastic polymers. The average number of MPs was at its highest level in Siganus rivulatus, Diplodus sargus, and Sardinella aurita (7527, 3593, and 1450MPs fish, resp.) and the lowest in Sphyraena viridensis and Atherina boyeri (46 and 28MPs fish, respectively). The average weight of MPs as measured by combustion ranged from 302mg kg in S. rivulatus to 2mg kg in Terapon puta.

Characterization and distribution of plastic particles along Alexandria beaches, Mediterranean Coast of Egypt, using microscopy and thermal analysis techniques
AI summary Read the abstract
Researchers characterized plastic particles in sediments and surface water along Alexandria beaches in Egypt, finding mean concentrations of 389 items per kilogram dry sediment and 457 items per cubic meter in surface water. Thermogravimetric and calorimetric analysis identified 10 polymer types, with low-density polyethylene dominant, and linked contamination primarily to single-use plastic bags, detergent packaging, and seafaring activities.
