Dr. Hossain is currently focusing on ecosystem and human health exposure to microplastics and emerging contaminants. His work specifically aims to address critical questions, such as identifying appropriate threshold values for human exposure to microplastics and developing toxicity sensitivity distributions to assess the adverse health effects of microplastic exposure, which will help establish these exposure thresholds. He has authored over 200 scientific publications and discovered five new invertebrate species from Bangladesh’s coastal waters. According to Scopus, he is the top-ranked researcher at NSTU, with over 5900 citations and an h-index of 39. He also serves as a Guest Editor and reviewer for numerous prestigious journals, including Biology, Marine Pollution Bulletin, Science of the Total Environment, Scientific Reports, and Environmental Pollution.
Dr. Mohammad Belal Hossain is a Professor of Marine Biology (currently on study leave) in the Department of Fisheries and Marine Science at Noakhali Science and Technology University, Bangladesh. He holds an MSc in Estuarine Science from the University of Hull, United Kingdom, and a PhD in Estuarine Benthic Ecology from Universiti Brunei Darussalam. He subsequently completed postdoctoral research at the Australian Museum Research Institute in Sydney, Australia. With over two decades of research experience, Dr. Hossain's expertise encompasses benthic ecology, biodiversity assessment, aquatic pollution, marine fisheries, and coastal aquaculture. He was a professional member of the Australian Marine Sciences Association and the Scottish Association for Marine Science.

Thesis Title: Assessment of heavy metal pollution, distribution and source apportionment in the sediment from Feni River estuary, Bangladesh
Overview: Heavy metal pollution in sediment resources may pose serious threat to ecosystem and human health through food web. In this study, surface sediment samples of 10 stations along the Feni River estuary were analyzed to profile the accumulation, sources and pollution levels of heavy metals. The results revealed that the average contents (μg g−1) of eight selected heavy metals followed the order of Mn (37.85) > Cr (35.28) > Ni (33.27) > Co (31.02) > Pb (6.47) > Ag (1.09) > As (0.85) > Hg (0.71), and the concentrations varied spatially and seasonally with relatively higher levels at upward stations and during the rainy season. According to sediment quality guidelines (SQGs), the sediment samples were heavily contaminated with Ag and Hg, and moderately with Co. Threshold effect concentration (TEC) and probable effect concentration (PEC) values indicated that the concentration of only Ni and Cr were likely to occasionally exhibit adverse effects on the ecosystem. Enrichment factor (EF), geo-accumulation index (Igeo) and contamination factor (CF) analyses revealed that Ag, Co and Hg were at moderate to high pollution levels and the rests (As, Cr, Ni, Pb and Mn) were at no to low pollution levels. Potential ecological risk index (PERI) also showed that Ag, Co and Hg were the most potential ecological risk factor being determined in this studied area. Correlation matrix combined with multivariate principal component analysis and cluster analysis suggest that Ag, Co, Ni and Hg originated from anthropogenic sources (agrochemicals, silver nanoparticles anti-microbial agent, silver plating), whereas As, Cr, Pb and Mn primarily originated from natural geological background.
Thesis Title: Performance of monosex fry production of two Nile tilapia strains: GIFT and NEW GIPU
Overview: Enter Project/Thesis OA study was conducted to know the performance of GIFT and NEW GIFU tilapia to produce monosex tilapia for a period of 4 months from March to June, 2010 by using controlled on-station experimentation. The egg production, hatching rate and fry survival rate in both strains were assessed to know their performance. For monosex fry production, fertilized eggs were collected from the female mouth directly from breeding hapas placed in pond and were kept in jar incubation system in hatchery. Fries were obtained after an incubation period of 90-96 hours. The highest (118.33 eggs/female of GIFT tilapia and 334.61 eggs/female of NEW GIFU tilapia) egg production was found in March and the lowest (23 eggs/female of GIFT tilapia and 28.73 eggs/female of NEW GIFU tilapia) egg production was found in May. The monthly average egg production (138.34±134.6725 no./female), average hatching rate (54%±0.0465) and average fry survival rate (73.20%±0.0564) were found in NEW GIFU tilapia which were higher than that of the GIFT tilapia strain (monthly average egg production 63.08±40.92 no./female, average hatching rate 50.34%±0.0295 and average fry survival rate 70.21%±0.0476). The androgen hormone 17-"-Methyltestosterone (MT) was administered orally to the three day old fry at their first feeding stage at the dose of 60 mg/kg feed. After hormone treatment, the treated fries were transferred to hapas placed in pond for further rearing (21 days). The results demonstrate that the dose of MT-60 for 21 days was sufficient to produce 95% male population of the GIFT strain and 99% male population of the NEW GIFU strain.
