My research focuses mainly on heavy metal and metalloid pollution in soil, water and plant species. I work both on content of heavy metals in different environmental segments and also uptake of heavy metals in different plant species and potential health risk assessment.
Currently on -going project (2022-24)
Effect of biochar on heavy metal availability and plant uptake from the contaminated soils
We have investigated effect of biochar doses on different kind of contaminated soils from the member states of the European Union (EU) and assess the the availability of heavy metals in the rhizosphere zone and in the edible parts of plants.
The project has received fund from the Crafoord Foundation in the year of (2022-23). Associate Prof. Anna Augustsson (PI) and Dr. Arifin Sandhi (Co-PI) from Dept. of Biology and Environmental Sciences, Linnaeus University, Kalmar, Sweden
Currently, the data analysis and their interpretation from this project is on-going.

Sampling of aquatic plant species, sediment and water from the streams
on -going project (2022-24)
Heavy metal content in the aquatic plant species and potential use of floating wetland systems for removal of heavy metals from the contaminated water.
We have started our new project about assessment of heavy metal content in the sediment, water and aquatic plants species and their potential for floating wetland system in the contaminated glassworks sites located in Kalmar-Kronoberg municipalities.
The project has received fund from Swedish Engineers Association in the year of (2022-23). Both Linnaeus University and Halmstad University (www.hh.se) has involved in this project.
Currently, an undergraduate student at Linnaeus University has started her thesis work under this project.
Using bioenergy plant species (Salix spp.) for phytormediation of contaminated sediment, Oskarshamn, SWEDEN
The removal of heavy metals from the excavated harbour sediment in an environment-friendly way has not investigated yet, especially in the harbours located in South-east of Sweden. Previous works have found that sediment from those harbours high level of cadmium (Cd), copper (Cu), zinc (Zn) and lead (Pb) on it. Using plant-based heavy metal remediation or Phytoremediation could be an effective and eco-friendly method that could apply for cleaning up this excavated sediment from there.

Aquatic moss and phytofiltration of arsenic
High arsenic content in the mining water, especially iron mines located in the northern part of Sweden is one of environmental problems in Sweden. The mining water reaches to the outside of mine and increases arsenic concentration in both soil and water resources in the surrounding system. This high concentration of arsenic in the wetland becomes more available to the plants and animals.
Reducing arsenic concentration in the mining water in a sustainable and environment friendly way was focused in this investigation. Our aim for this study was to investigate the potential aquatic moss for rapid reduction of arsenic from the contaminated water system. Our findings show that aquatic moss could reduce arsenic content within a very short term and this is considered as one of arsenic hyperfilter plant species.
We have published 2 papers regarding arsenic uptake and different environmental factors towards arsenic accumulation in aquatic moss in Journal of Environmental Pollution and Environmental Chemical Engineering from Elsevier.

Arsenic related health risk by consumption of rice
Presence of high levels of arsenic in the groundwater has been considered one of the major environmental disasters in the south-East Asia region. The groundwater resources have been used for both drinking water and irrigation purposes. The high arsenic in the groundwater could transfer to the food chain as plants could accumulate arsenic from both surrounding soil and water. Due to high water demand for production, the farmers in Asian countries have used high amount of groundwater based irrigation in their agricultural fields
The aim of this investigation was to assess arsenic content in commercial hybrid rice cultivars and local aromatic rice cultivars in one of arsenic hotspots located in Bangladesh. We have also calculated health risk due to the consumption of those rice cultivars.

Salix spp. and their arsenic phytoremediation potential
Saix is one of the most popular short rotation energy crop species in Europe. A number of local and commercial varieties have developed for a long period of time and use them for bioenergy production especially in Scandinavian countries. Meanwhile, high arsenic (carcinogenic metalloid) content in soil and water is also a problem for developed countries, where arsenic has been used for wood impregnation for a long time.
Our short investigation has found some new information about arsenic accumulation in 2 Swedish commercial Salix clones and also one from Slovakia. We have done an investigation in controlled climate chamber conditions at Stockholm University, Stockholm, Sweden.
The findings have been disseminated in several international conferences including, ICOBTE, 2011, As conference 2012.
