ClearAssessment and treatment of microplastics in different environmental compartments of Kallar Kahar Lake—a case study
Researchers quantified and characterized microplastics in surface water, sediments, and fish from Kallar Kahar Lake in Punjab, Pakistan, and tested magnetization and coagulation-flocculation as removal methods. Both treatments reduced MP concentrations in water samples, providing early data on freshwater MP pollution in Pakistan and demonstrating accessible treatment options for lake water management.
Plastic driven pollution in Pakistan: the first evidence of environmental exposure to microplastic in sediments and water of Rawal Lake
This study provides the first evidence of microplastic contamination in a freshwater body in Pakistan, examining surface water and sediments of Rawal Lake near Islamabad. Researchers found microplastics in both water and sediment samples, with fibers and fragments being the most common types, composed primarily of polyethylene, polypropylene, and polyester. The study suggests that high population density, improper waste disposal, and recreational activities are the main drivers of contamination.
Comprehensive analysis of spatial distribution of microplastics in Rawal Lake, Pakistan using trawl net and sieve sampling methods
Researchers conducted a comprehensive spatial analysis of microplastics in Rawal Lake, Pakistan, finding that sampling methodology significantly influences microplastic counts and revealing widespread contamination across tributaries, settlement areas, and fishing zones.
Microplastics abundance in abiotic and biotic components along aquatic food chain in two freshwater ecosystems of Pakistan
Researchers quantified microplastic abundance across multiple trophic levels in two Pakistani freshwater ecosystems, finding evidence of bioaccumulation along the food chain from water and sediment through invertebrates to fish species.
Detection in influx sources and estimation of microplastics abundance in surface waters of Rawal Lake, Pakistan
Researchers detected microplastics in four of six major tributaries feeding Rawal Lake in Islamabad, Pakistan, with lake surface water concentrations ranging from 6.4 to 8.8 particles/m3, identifying tributary inflow as a primary pathway for microplastic contamination of this urban freshwater reservoir.
Characterization and implication of microplastics on riverine population of the River Ravi, Lahore, Pakistan
Researchers found microplastics in three commercially important freshwater fish species from the River Ravi in Pakistan, with Raman spectroscopy confirming multiple polymer types, indicating widespread contamination of riverine fish populations and potential implications for human dietary exposure in the region.
An unintended challenge of microplastic pollution in the urban surface water system of Lahore, Pakistan
Researchers conducted the first investigation of microplastic pollution in the urban freshwater systems of Lahore, Pakistan, sampling surface water and sediments from drains and canals of the Ravi River and finding highest microplastic concentrations in heavily polluted sullage carriers.
Co-occurrence of microplastics and heavy metals in a freshwater lake system in Indian Himalaya: Distribution and influencing factors
Researchers found widespread microplastic contamination in both the water and sediments of Manasbal Lake in the Indian Himalayas, with concentrations up to 4,020 particles per kilogram of sediment. Domestic sewage was identified as the primary source, and the microplastics were found alongside elevated levels of heavy metals like lead. This co-contamination is concerning because microplastics can absorb and transport heavy metals, potentially increasing toxic exposure for communities that depend on the lake.
Risk assessment of microplastics in fish assemblage based on ecological preferences in an interconnected and polluted river system
Researchers assessed microplastic contamination across 15 fish species with different feeding habits in Pakistan's River Ravi, finding that bottom-dwelling and omnivorous fish accumulated more microplastics, with contamination levels posing ecological risk.
Quantifying Microplastics Abundance and Their Implications as Vectors for Heavy Metal Adsorption in Freshwater Aquatic System of Kashmir Himalaya
Researchers measured microplastic abundance in both water and sediment of Manasbal Lake in the Kashmir Himalaya and examined how the particles interact with heavy metals. Microplastics were found throughout the lake and showed capacity to adsorb heavy metals, raising dual concerns about plastic particles and metal contamination in a sensitive Himalayan freshwater system.
Evidence of microplastic contamination in the food chain: an assessment of their presence in the gastrointestinal tract of native fish
Researchers found microplastics, mainly polyethylene and polypropylene, in the guts of fish from the Swat and Kabul rivers in Pakistan. These rivers are primary freshwater sources for the region, and the contaminated fish are regularly consumed by local communities. The findings confirm that freshwater fish from polluted rivers are a pathway for microplastic exposure in people's diets.
Unveiling microplastics pollution in a subtropical rural recreational lake: A novel insight
Researchers conducted the first detailed assessment of microplastic pollution in a rural recreational lake in Bangladesh, analyzing both water and sediment samples. They found microplastics present throughout the lake, with fragments and fibers being the most common types, likely originating from agricultural runoff and recreational activities. The study reveals that microplastic contamination extends well beyond urban waterways into rural environments that have received little scientific attention.
Unveiling the Microplastics Menace in Freshwater Fishes: Evidence from the Panjnad Barrage, South Punjab, Pakistan
Researchers examined microplastic contamination in three freshwater fish species from the Panjnad Barrage in Pakistan, analyzing gastrointestinal tracts, gills, and muscle tissue. The gastrointestinal tract consistently had the highest microplastic counts, while gills showed the highest concentration per gram. Polypropylene and polyethylene were the primary polymers found, and the predatory species Wallago attu accumulated the most microplastics, likely due to its feeding habits.
The measurement of microplastics in surface water and their impact on histopathological structures in wading birds of district Lahore
Researchers measured microplastic pollution in surface water around Lahore, Pakistan, and examined its effects on local wading birds. The Ravi River had the highest contamination, with over 5,000 particles per cubic meter, and birds living near these waters showed tissue damage in multiple organs. This study demonstrates that microplastic pollution in urban waterways can harm wildlife and may indicate broader risks for communities relying on these water sources.
Microplastic assessment in remote and high mountain lakes of Gilgit Baltistan, Pakistan
Researchers assessed microplastic contamination in eight remote, high-altitude lakes in the mountains of northern Pakistan, finding plastic particles in both water and sediment at all locations. Despite the lakes being far from major population centers, microplastics were present at measurable levels, likely transported by wind and water from lower elevations. The contamination of these pristine mountain lakes is concerning because they serve as water sources for local communities.
Microplastic contamination from surface waters and commercially valuable fishes of Karachi Coast, Pakistan
Researchers found widespread microplastic contamination in surface waters and gastrointestinal tracts of 15 commercial fish species from Karachi coast, Pakistan, with fibers being the dominant type and higher concentrations near the harbor.
