| 1 | Sources and Ecological Risks of Heavy Metals in Soils Under Different Land Uses in Bangladesh显示文摘Soil heavy metal pollution, influenced by both natural and anthropogenic factors, significantly reduces environmental quality. In this study, Cr, Ni, Cu, As, Cd, and Pb in eight different land-use soils from Patuakhali District in Bangladesh were assessed. Concentrations of Cr, Ni, Cu, As, Cd, and Pb in soils were 1-87, 5-271, 4-181, 0-80, 0.2-24.0, and 5-276 mg kg-1, respectively, measured using an inductively coupled plasma-mass spectrometer. The enrichment factor, pollution load index (PLI), and contamination factor (CJ) of metal i were used to assess the ecological risk posed by metals in soils. The PLI ranged from 0.78 to 2.66, indicating baseline levels to progressive deterioration of soil due to metal contamination. However, C;of Cd ranged from 1.8 to 12.0, which showed that the studied soils were strongly impacted by Cd. Considering the severity of the potential ecological risk of a single metal, the descending order was Cd > As > Pb > Cu > Ni > Cr. Soils under all land uses showed moderate to very high potential ecological risk. | Mohammad Saiful ISLAM Mohammad Kawser AHMED Mohammad Habibullah AL-MAMUN Shah Mohammad Asraful ISLAM | 2019 | Pedosphere2019，29，5： | 5 |

| 3 | Spatiotemporal variation and mechanisms of temperature inversion in the Bay of Bengal and the eastern equatorial Indian Ocean显示文摘In the northern Bay of Bengal,the existence of intense temperature inversion during winter is a widely accepted phenomenon.However,occurrences of temperature inversion during other seasons and the spatial distribution within and adjacent to the Bay of Bengal are not well understood.In this study,a higher resolution spatiotemporal variation of temperature inversion and its mechanisms are examined with mixed layer heat and salt budget analysis utilizing long-term Argo(2004 to 2020)and RAMA(2007 to 2020)profiles data in the Bay of Bengal and eastern equatorial Indian Ocean(EEIO).Temperature inversion exists(17.5%of the total 39293 Argo and 51.6%of the 28894 RAMA profiles)throughout the year in the entire study area.It shows strong seasonal variation,with the highest occurrences in winter and the lowest in spring.Besides winter inversion in the northern Bay of Bengal,two other regions with frequent temperature inversion are identified in this study for the first time:the northeastern part of the Bay of Bengal and the eastern part of the EEIO during summer and autumn.Driving processes of temperature inversion for different subregions are revealed in the current study.Penetration of heat(mean~25 W/m;)below the haline-stratified shallow mixed layer leads to a relatively warmer subsurface layer along with the simultaneous cooling tendency in mixed layer,which controls more occurrence of temperature inversion in the northern Bay of Bengal throughout the year.Comparatively lower cooling tendency due to net surface heat loss and higher mixed layer salinity leaves the southern part of the bay less supportive to the formation of temperature inversion than the northern bay.In the EEIO,slightly cooling tendency in the mixed layer along with the subduction of warm-salty Arabian Sea water beneath the cold-fresher Bay of Bengal water,and downwelling of thermocline creates a favorable environment for forming temperature inversion mainly during summer and autumn.Deeper isothermal layer depth,and thicker barrier layer thickness intensify the temperature inversion both in the Bay of Bengal and EEIO. | K M Azam Chowdhury Wensheng Jiang Guimei Liu Md Kawser Ahmed Shaila Akhter | 2022 | Acta Oceanologica Sinica2022，41，4： | 1 |
| 4 | The response of the upper ocean to tropical cyclone Viyaru over the Bay of Bengal显示文摘Better forecast of tropical cyclone(TC) can help to reduce risk and enhance management. The TC forecast depends on the scientific understanding of oceanic processes, air-sea interaction and finally, the atmospheric process. The TC Viyaru is taken as an example, which is formed at the end of 11 May 2013 and sustains up to 17 May 2013 during pre-monsoon season. Argo data are used to investigate ocean response processes by comparing pre-and post-conditions of the TC. Eight oceanic parameters including the sea surface temperature(SST), the sea surface salinity(SSS), and the barrier layer thickness(BLT), the 26°C isotherm depth in the ocean(D26), the isothermal layer depth(ILD), the mixed layer depth(MLD), the tropical cyclone heat potential(TCHP) and the effective oceanic layer for cyclogenesis(EOLC) are chosen to evaluate the pre-and post-conditions of the TC along the track of Viyaru. The values of the SST, D26, BLT, TCHP and EOLC in the pre-cyclonic condition are higher than the post-cyclonic condition, while the SSS, ILD and MLD in the post-cyclonic condition are higher than the pre-cyclonic condition of the ocean due to strong cyclonic winds and subsurface upwelling. It is interesting that the strong intensity of the TC reduces less SST and vice versa. The satisfied real time Argo data is not available in the northern Bay of Bengal especially in the coastal region. A weather research and forecasting model is employed to hindcast the track of Viyaru, and the satellite data from the National Center Environmental Prediction are used to assess the hindcast. | Mir Kashem Md Kawser Ahmed Fangli Qiao M A E Akhter K M Azam Chowdhury | 2019 | Acta Oceanologica Sinica2019，38，1： | 1 |

| 15 | Greywater reuse as a key enabler for improving urban wastewater management显示文摘Sustainable water management is essential to guaranteeing access to safe water and addressing the challenges posed by climate change,urbanization,and population growth.In a typical household,greywater,which includes everything but toilet waste,constitutes 50e80%of daily wastewater generation and is characterized by low organic strength and high volume.This can be an issue for large urban wastewater treatment plants designed for high-strength operations.Segregation of greywater at the source for decentralized wastewater treatment is therefore necessary for its proper management using separate treatment strategies.Greywater reuse may thus lead to increased resilience and adaptability of local water systems,reduction in transport costs,and achievement of fit-for-purpose reuse.After covering greywater characteristics,we present an overview of existing and upcoming technologies for greywater treatment.Biological treatment technologies,such as nature-based technologies,biofilm technologies,and membrane bioreactors(MBR),conjugate with physicochemical treatment methods,such as membrane filtration,sorption and ion exchange technologies,and ultraviolet(UV)disinfection,may be able to produce treated water within the allowable parameters for reuse.We also provide a novel way to tackle challenges like the demographic variance of greywater quality,lack of a legal framework for greywater management,monitoring and control systems,and the consumer perspective on greywater reuse.Finally,benefits,such as the potential water and energy savings and sustainable future of greywater reuse in an urban context,are discussed. | Arjen Van de Walle Minseok Kim Md Kawser Alam Xiaofei Wang Di Wu Smruti Ranjan Dash Korneel Rabaey Jeonghwan Kim | 2023 | Environmental Science and Ecotechnology2023，，4： | 0 |
| 16 | Protective Roles of Some Leafy and Non-leafy Vegetables against the Severity of Arsenic-induced Skin Lesions among Women Living in Rural Bangladesh:A Case Control Study显示文摘Arsenicosis is common among villagers as they drink more contaminated-water since the arsenic-crisis in Bangladesh.Supplementation of vitamins and micronutrients in counteracting arsenic toxicity has been proved for arsenic treatment.This study was intended to assess protective and beneficial roles of some commonly eaten vegetables on the development and severity of arsenic-induced skin lesions.A case-control study among(N=122)adult rural-women(62 cases had various forms of arsenical skin-lesions e.g.melanosis/keratosis/mixed-lesions and 60 sex-age-matched healthy-controls)was conducted in Shaharstee Upazilla of Chandpur district,Bangladesh.Socio-demographic data recorded in a pre-tested-questionnaire,‘per-day vegetables ingestion’of cases and controls were measured qualitative and quantitatively(24-hour recall-methods,food-frequency/week and food history-record/week).Multiple logistic regression/MLR analyses were performed to find out protective roles of some dietary leafy-vegetables/LVs and non-leafy vegetables/NLVs on arsenicosis and their influences on the degree of severity of arsenicosis also determined.Abstinence from taking some LVs/NLVs among cases than controls is associated with increased risk for arsenicosis(P<0.05).Amongst all most-frequently eaten vegetables(n=17)per day Momordica diocia has the highest skin protective role on arsenicosis[Adjusted odds ratio/AOR 8.2,95%CI(2.11-31.9),P=<0.01],followed by Ipomoea acquatica(AOR:7.3),Basella alba(AOR:6.2),Solanum tuberosum(AOR:4.0),Vigna unguiculata sesquipedalis(AOR:3.2),Trichosanthes anguina(AOR:1.2)and Abelmoschus esculentus(AOR:1.2).Moreover,severe skin lesion was observed as compared to non-severe cases(mild/moderate)for less intake frequencies of vegetables.This study outlined that commonly eaten vegetables have protective and beneficial roles on arsenic-induced skin lesions.Large samples longitudinal study of this important field of therapeutic-intervention is warranted. | Shayla Nasrin Mahbuba Kawser Selim Ahmed Anup Kumar Saha Anamul Haque Rufaida Rahman Akhi Akter Sheikh Nazrul Islam | 2022 | Journal of Botanical Research2022，4，1： | 0 |

| 18 | Contributions of shortwave radiation to the formation of temperature inversions in the Bay of Bengal and eastern equatorial Indian Ocean:A modeling approach显示文摘Variations in incoming shortwave radiation influence the net surface heat flux,contributing to the formation of a temperature inversion.The effects of shortwave radiation on the temperature inversions in the Bay of Bengal and eastern equatorial Indian Ocean have never been investigated.Thus,a high-resolution(horizontal resolution of 0.07°×0.07° with 50 vertical layers) Regional Ocean Modeling System(ROMS) model is utilized to quantify the contributions of shortwave radiation to the temperature inversions in the study domain.Analyses of the mixed layer heat and salt budgets are performed,and different model simulations are compared.The model results suggest that a 30% change in shortwave radiation can change approximately 3% of the temperature inversion area in the Bay of Bengal.Low shortwave radiation reduces the net surface heat flux and cools the mixed layer substantially;it also reduces the evaporation rate,causing less evaporative water vapor losses from the ocean than the typical situation,and ultimately enhances haline stratification.Thus,the rudimentary outcome of this research is that a decrease in shortwave radiation produces more temperature inversion in the study region,which is primarily driven by the net surface cooling and supported by the intensive haline stratification.Moreover,low shortwave radiation eventually intensifies the temperature inversion layer by thickening the barrier layer.This study could be an important reference for predicting how the Indian Ocean climate will respond to future changes in shortwave radiation. | K M Azam Chowdhury Wensheng Jiang Changwei Bian Guimei Liu Md Kawser Ahmed Shaila Akhter | 2022 | Acta Oceanologica Sinica2022，41，9： | 0 |
