Water Quality Assessment and Monitoring in Pakistan: A Comprehensive Review
This comprehensive review examines water quality issues across Pakistan, including contamination from industrial discharge, agricultural runoff, and emerging pollutants like microplastics. The review found that water treatment infrastructure in many areas is inadequate, leaving large populations exposed to contaminated water. While focused on Pakistan, the findings illustrate how developing countries face compounding water quality challenges that include growing microplastic pollution.

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.
A Study on Comparative Assessment of Water Quality of Dal and Nigeen Lakes of Jammu and Kashmir, India

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.
Microplastics in freshwaters and drinking water: Critical review and assessment of data quality
Researchers critically reviewed fifty studies on microplastics in freshwater and drinking water and found significant quality issues, including inconsistent sampling methods and inadequate contamination controls. Many studies lacked proper quality assurance, making it difficult to draw reliable conclusions about actual contamination levels. The study emphasizes that standardized methods are urgently needed before the true extent of microplastic contamination in drinking water can be assessed.
A standard analytical approach and establishing criteria for microplastic concentrations in wastewater, drinking water and tap water
This study proposes standardized methods and concentration benchmarks for measuring microplastics in wastewater, drinking water, and tap water. The researchers found that current studies use widely varying techniques, making it difficult to compare results or set safety limits. Establishing consistent measurement standards is a critical first step toward determining what levels of microplastics in drinking water may pose risks to human health.
Assessment 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.
Assessment of wastewater impact on a natural reservoir in Kyrgyzstan
This paper is not directly about microplastics; it assesses water pollution in Kyrgyzstan's natural reservoirs caused by inadequate wastewater treatment and industrial discharges, evaluating impacts on aquatic ecosystems and public health and recommending improved treatment infrastructure.
Microplastic contamination and risk assessment in the biotic and abiotic components of freshwater Manasbal Lake, western Himalaya, India
Researchers assessed microplastic abundance and characteristics across abiotic and biotic compartments of Manasbal Lake in the western Himalayas, finding that MPs are pervasive even in remote mountain catchments and presenting risk assessment data for this understudied high-altitude freshwater ecosystem.
Microplastic contamination and risk assessment in the biotic and abiotic components of freshwater Manasbal Lake, western Himalaya, India
Researchers assessed microplastic abundance and characteristics across abiotic and biotic compartments of Manasbal Lake in the western Himalayas, finding that MPs are pervasive even in remote mountain catchments and presenting risk assessment data for this understudied high-altitude freshwater ecosystem.
A Comparative Analysis of Public Awareness Level about Drinking Water Quality in Guangzhou (China) and Karachi (Pakistan)
Researchers compared public awareness of drinking water quality between Guangzhou, China and Karachi, Pakistan, finding significant differences in knowledge levels and concerns about contaminants including microplastics and heavy metals.
Presence of microplastics in drinking water from freshwater sources: the investigation in Changsha, China
Researchers measured microplastic abundance at multiple stages of a drinking water supply chain in Changsha, China — from source freshwater through treatment to household taps — finding that water treatment reduced MP concentrations by more than 85% but tap water still contained an average of 344 particles per liter.
Physicochemical and pathological assessment of groundwater quality from Sargodha, Pakistan using hybrid multi-layer slow sand filter: pre and post treatment analysis

Microplastics in freshwater lakes: A case study from Southern India
Researchers assessed microplastic contamination in Vellayani Lake, a major drinking water source in southern India, and found particles present across all sampling sites and seasons. Fibers were the most common shape, with polyethylene and polypropylene as the dominant polymer types, likely originating from domestic wastewater and fishing activities. The study highlights the need for monitoring microplastic pollution in freshwater lakes that serve as critical drinking water supplies.

Microplastic pollution in high-altitude Nainital lake, Uttarakhand, India
This is the first study to document microplastic contamination in Nainital Lake, a high-altitude lake in the Indian Himalayas that serves as the main drinking water source for the local town. Researchers found microplastics in every sample, with concentrations up to 56 particles per liter in lake water. Tourist activities and runoff were identified as the main pollution sources, raising concerns about drinking water safety for the local population.
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.
