Characterization of odorants in contrasting ecotypes of Lake Taihu: algae-dominated versus macrophyte-dominated zones

Temporal Dynamics and Influential Factors of Taste and Odor Compounds in the Eastern Drinking Water Source of Chaohu Lake, China: A Comparative Analysis of Global Freshwaters

“…Notably, certain T/O compounds in specific water bodies exhibit peak concentrations in other seasons, which recommended involving winter data in future predictions models ([ 96 ] and this study). Moreover, studies also emphasized the temporal variability of odor occurrences within the same water body across different years, which could be attributed to various factors, including environmental conditions, biological dynamics, water mixing patterns, and anthropogenic influences [ 11 , 22 , 23 , 33 , 35 , 42 , 64 , 65 ]. A comprehensive understanding of the temporal dynamics of odor events was crucial in developing water quality management and treatment strategies, facilitating the recognition of patterns and trends, and furnishing essential information for the establishment of early warning systems.…”

“…Considering that the concentrations of both CYC and ION can reach 6000 and 8300 ng•L −1 , respectively, in the field [33,45,69], it is advisable to include them in the scope of detection, as well (Table 4).

In terms of management and monitoring, it is crucial to recognize that many studies do not provide year-round coverage and tend to favor observations during these two seasons.…”

“…These compounds, stemming from the degradation of β -carotene, exhibit distinctive odors reminiscent of wood, violets, tobacco, and flowers and have been scrutinized in certain water sources [ 30 , 31 , 32 ]. The simultaneous presence of multiple T/O compounds introduces complexity to water quality management and constitutes a significant concern in the context of natural and drinking water in several countries, including China [ 11 , 12 , 22 , 33 , 34 , 35 ].…”

Editorial special issue on cyanobacterial blooms and water ecological restoration

“…They found that short-term nutrient release during a typhoon did not result in an obvious increase in Microcystis cell density but the horizontal migration of Microcystis colonies would be the reason why the area of a cyanobacterial bloom increases in Lake Taihu after a typhoon passes. Qi et al (2020) focused on the concentration and characterization of odorants in Lake Taihu and found that the concentration in the water of cyanobacterial blooms zones was approximately 3 to 21 times higher than that in macrophyte-dominated zones. An outdoor mesocosm water ecological restoration experiment was conducted in Lake Taihu by Han et al (2019), and their results suggested that it was necessary to continuously remove the juvenile benthivorous fish several times for restoring the submerged macrophytes in shallow lakes.…”
