“…While some lakes are nitrogen limited, 123 most lakes in California are phosphorus limited. 42,44,124,125 The concentration of nitrogen-containing species was higher during the case study fires, yet these species were also present in the air during non-fire days. By contrast, phosphorus was only present at the case study locations in smoke plumes and absent on non-smoke days (Fig.…”

“…35,36 Sixty-three small streams drain the 800 km 2 forested watershed surrounding Lake Tahoe. 35,37 Two large gyres contribute to mixing, one to the north and one in the south-central region. 38 The lakebed is characterized by a narrow and flat nearshore zone with cobble and boulder zones, followed by a steep slope to the lakebed, 39 and the lake floor is covered with mud and clay sediment.…”

Monitoring plastic litter in the environment is critical to understanding the amount, sources, transport, fate, and environmental impact of this pollutant. However, few studies have monitored plastic litter on lakebeds which are potentially important environments for determining the fate and transport of plastic litter in freshwater basins. In this study, a self-contained underwater breathing apparatus was used for litter collection at the lakebed along five transects in Lake Tahoe, United States. Litter was brought to the surface and characterized by litter type. Plastic litter was subsampled, and polymer composition was determined using attenuated total reflection Fourier transform infrared spectroscopy. The average plastic litter from the lakebed for the five dive transects was 83 ± 49 items per kilometer. The top plastic litter categories were other plastic litter (plastic litter that did not fall in another category), followed by food containers, bottles <2 L, plastic bags, and toys. These results are in line with prior studies on submerged litter, and intervention approaches or ongoing education are needed. The six polymers most frequently detected in the subsamples were polyvinyl chloride, polystyrene/expanded polystyrene, polyethylene terephthalate/polyester, polyethylene, polypropylene, and polyamide. These observations reflect global plastic production and microplastic studies from lake surface water and sediments. We found that some litter subcategories were primarily comprised of a single polymer type, therefore, in studies where the polymer type cannot be measured but litter is categorized, these results could provide an estimate of the total polymer composition for select litter categories.

“…However, as surface water has a large amount and widely distribute, it could not be remediated by traditional centralized treatment technology, such as traditional coagulation sedimentation for the polluted surface water (e.g., adsorption, extraction, ion exchange, and membrane separation). Moreover, the contaminated surface waters are generally characterized by a relatively low concentration of pollutants compared to that of raw wastewater, e.g., total nitrogen (TN) < 10 mg/L and total phosphorus (TP) < 1.0 mg/L, so it might not be effective and economic to use the treatment technologies and equipment used for domestic sewage or industrial wastewater treatment [20]. Therefore, it is urgent to develop novel remediation technologies to prevent the deterioration of surface water quality (e.g., eutrophication) and maintain a healthy aquatic ecosystem.…”

To realize the integrated remediation of SW/GW and soil in the rural river network area, the integrated remediation in rural river network area project (IR-RRNA), funded by the Ministry of Science and Technology of the People’s Republic of China, has been launched. In eastern China, the rural river network area (RRNA) is an anthropic active area characterized by its rapid economic development and high gross national product. However, the water environmental pollution in these areas is increasingly severe, which has greatly hindered their sustainable development. Especially, the frequent interactions between surface/groundwater (SW–GW) have intensified the pollution migration and transformation in RRNA. The IR-RRNA (2019–2022) will apply the related interdisciplinary and methodological knowledge to elucidate the transportation and transformation of pollutants in water and soil during SW–GW interaction and develop remediation technologies of surface water, groundwater, and soil suitable for the RRNA. In this way, to realize the remediation technologies integration for surface/groundwater and soil in RRNA and implementing application demonstration. Meanwhile, a technical guideline will be compiled for the integrated remediation suitable for the RRNA. This project is conducive to addressing the urgent environmental problems as well as promoting rural economic revitalization and ecological environment optimization.
