Contaminação de canais urbanos por microplástico em uma capital da Amazônia
AI summary Read the abstract
Researchers investigated microplastic contamination in urban drainage canals of an Amazonian capital city, assessing particle distribution and abundance in a region with rapid urban growth and limited solid waste infrastructure. The dissertation documents microplastic presence as a consequence of inadequate waste management in tropical urban waterways.

Detection of Possible Polluting Microplastics in the Paragominas Stream, Municipality of the Same Name, Pará, Brazil
AI summary Read the abstract
Researchers investigated whether microplastics are present in water and sediment along the urban stretch of the Paragominas stream in Pará, Brazil. MPs were detected in both matrices, with shape and color analysis pointing to urban runoff and plastic waste disposal as primary local sources of contamination.

AI summary Read the abstract
Researchers found increasing microplastic concentrations along the Yamuna River in Delhi, with levels rising from 500 MP/m3 upstream to 3,900 MP/m3 downstream near major drain outfalls, alongside elevated heavy metal and fecal coliform contamination.
Influence of Urbanization and Seasonality on Microplastics in a Small Brazilian Inland Stream
AI summary Read the abstract
Researchers sampled a small Brazilian inland stream upstream and downstream of an urban center during dry and rainy seasons, finding urbanization significantly increased microplastic abundance from 1.7 to 2.6 particles per liter during the dry season, while rainfall effects were less consistent.
Urban drainage channels as a pathway for microplastics in riverine systems: A case study of Delhi, India
AI summary Read the abstract
Researchers measured microplastics in Delhi's Najafgarh drain, secondary drains, and the Yamuna River, finding concentrations of 100-6,700 particles per cubic meter in secondary drains with clear seasonal variation. Urban drainage channels were identified as a major pathway for microplastics from terrestrial sources into the Yamuna River system.
