“…This has posed a threat to the security of drinking water sources in the lake. Wu et al [18] previously found that phytoplankton in Yangcheng Lake was the main driver of the 2-methylisoborneol (2-MIB). VOSCs have not been systematically studied in Yangcheng Lake, and it's not clear how phytoplankton relate to them.…”

Volatile organic sulfur compounds (VOSCs) function as a water–atmosphere link in the global sulfur cycle. It is generally believed that the vast majority of VOSCs are released from the ocean. However, due to the pervasive eutrophication and pollution of inland waters, the VOSC production and emission in rivers, lakes and reservoirs are attracting more attention. In this study, the temporal and spatial distributions of three VOSCs, including methanethiol, Dimethyl sulfide, and dimethyl disulfide in Yangcheng Lake, a eutrophic shallow lake, are investigated monthly and seasonally. Results show that VOSCs are higher in summer and autumn, with the western region as a hotspot. Our results show a positive correlation between VOSC and phytoplankton biomass (p < 0.05). Interestingly, from algal phylum composition, all the phylum, except those with low biomass, played a positive effect on VOSCs’ concentration. We did not find any specific phylum or species of cyanobacteria that contributed solely to the VOSCs. The water-air effluxes of Dimethyl sulfide (DMS) are estimated by a stagnant film model. The DMS effluxes from Yangcheng Lakes were higher than deep lakes and similar to the ocean, indicating that VOSCs, particularly DMS, in those eutrophic shallow lakes were non-negligible.

“…In order to avoid light stress, cyanobacteria reside at preferred depths in water bodies to avoid excess light exposure. Further, when the temperature reaches a maximum in the summer, cyanobacteria produce more odorous compounds (Wang & Li, 2015; Wu et al, 2021). Therefore, the application of the drawdown or circulation techniques used to suppress cyanobacterial growth via exposure to extreme conditions can promote the production of odorous compounds, which should be considered.…”

This study demonstrated the temporal variation of 2-methylisoborneol (2-MIB) and geosmin (GSM) production of two filamentous cyanobacteria species Pseudanabaena galeata (NIES-512; planktonic) and Phormidium ambiguum (NIES-2119; benthic) exposed to high light intensity (950-1000 μmol m À2 s À1 photosynthetically active radiation). The production of 2-MIB and GSM was quantified together with oxidative stress, chlorophyll content, and cellular protein content. The relative chlorophyll bleaching and cell degradations were compared through microscopic images. The 2-MIB production of P. galeata increased by over 42 ± 17% on the second day of exposure and remained leveled through the exposure period. P. ambiguum showed a continuous increase of 2-MIB until the 10th day, recording a 95 ± 4% increment. The GSM production was elevated until the fourth day of exposure by 46 ± 10% for P. galeata and by 74 ± 21% on the second day for P. ambiguum and reduced with prolonged exposure for both species. The chlorophyll content of P. galeata was reduced by 62 ± 7% on the second day, and that of P. ambiguum was reduced by 52 ± 9% on the fourth day and remained low. Protein and H 2 O 2 contents of both species were changed inconsistently. Exposure to high-intensity light can photobleach and deteriorate cells of both species, but elevations in odorous compounds can be expected.

“…Ultimately, the precise ecological triggers of 2-MIB and GSM production are unknown . However, 2-MIB and GSM are elevated during late spring through early fall when CHABs occur and are linked to periods with heightened nutrient concentrations. ,,, Concentrations of both compounds in eutrophic waterbodies range from <10 to >1000 ng L –1 , with averages ∼10 ng L –1 . , To date, only one study has reported ambient concentrations of airborne 2-MIB and GSM, which ranged from 0.16 to 0.31 μg L –1 and 0.01 to 0.25 μg L –1 in the airspace above soils, respectively . These VOCs share many structural characteristics with terpenoids such as α-pinene and camphor, two well documented precursors to vapor pressure-driven SOA. − To investigate aerosol formation as one transformation pathway for GSM and 2-MIB emissions, we oxidized GSM and 2-MIB in the gas phase with • OH in a series of experimental aerosol formation experiments.…”

Recent work has demonstrated the primary aerosolization of cyanobacterial cells, toxins, and metabolites from cyanobacterial harmful algal blooms (CHABs). However, another possible source of CHAB-derived aerosols is secondary organic aerosol (SOA) formation via the atmospheric oxidation of volatile organic compounds (VOCs) emitted by CHABs. To examine potential SOA formation from CHABs, two cyanobacterial VOCs2-methylisoborneol (2-MIB) and geosmin (GSM)were oxidized via hydroxyl radicals (•OH) in a potential aerosol mass-oxidation flow reactor. At 100 ppbv, SOA mass yields were 15.1 ± 2% and 33.9 ± 1.3%, from 2-MIB and GSM, respectively. SOA mass concentrations generated from 2-MIB and GSM oxidations reached up to 102 ± 22 μg m–3 and 252 ± 52 μg m–3, respectively, when exposed to 8–16 days of equivalent •OH exposure. Offline molecular-level characterization of Teflon-filter collected SOA by reverse-phase liquid chromatography interfaced to high-resolution quadrupole time-of-flight mass spectrometry equipped with electrospray ionization (RPLC/ESI-HR-QTOFMS) revealed 7 distinct chemical compounds in both 2-MIB and GSM-derived SOA, which we propose for use as molecular tracers of CHAB-derived SOA in ambient fine particulate matter (PM2.5). Two 2-MIB-derived SOA tracers (molecular formulas of C10H18O4 and C10H16O5) were measured in PM2.5 collected from the airshed of a CHAB. To the best of our knowledge, this is the first observation of respirable CHAB-derived SOA. Our findings strengthen the need to consider outcomes related to human respiratory health in risk assessments and public health messaging surrounding residential and recreational exposures to CHABs.
