This study was conducted to assess the concentration level of heavy metals in three available fish species (Bain, Mastacembelus armatus; Taki, Channa punctatus and Bele, Glossogobius giuris) of the Turag river, Bangladesh during the months from January to March, 2014. In case of bio-concentration of heavy metals in fish, the levels of Pb, Cd, Cr, Cu and Fe ranged from 0.01-0.13 mg/kg, 0.001-0.02 mg/kg, 0.17-0.48 mg/kg, 0.30-0.74 mg/kg and 4.05-46.86 mg/kg, respectively while Hg was below detection level. These values indicate that the heavy metals were concentrated in fish flesh at a higher level than water. The highest values of Pb, Cd and Cr were found in Bain fish, Fe was found in Taki fish and Cu was found in Bele fish. Most of the heavy metals have crossed the permissible limits in fish, especially for the values of Cr, Cu and Fe. From the results of the present investigation, it can be concluded that the available fish species are harmful for their consumers.

“…Regarding heavy metals of Turag River, the average values of Ni in three distinct seasons were 0.019 mg/L (pre-monsoon); 0.017 mg/L (monsoon) and 0.021 mg/L (post-monsoon) [25]. The highest value of Cd and Cr was observed in the Turag River were (0.03 ppm) and (0.02 ppm) [33]. The standard values of Cd for drinking, irrigation and livestock water are 0.005, 0.01 and 0.5 ppm, respectively [23].…”

Unplanned urbanization enhances environmental threats. Environmental threats increases water pollution that creates harmful impacts on the distribution of aquatic species. The present study is focused to evaluate the seasonal variation of water quality parameters in the Turagriver. Water samples were collected from 5 locations in north and south sides of the Turagriver during summer and winter seasons. The quality of water was found jeopardy. Dissolved oxygen (DO) of water samples were detected 4.9 to 5.7 mgL-1 during summer season. In winter, DO was found 0.78 to 0.95 mgL-1. The chemical oxygen demand (COD) was found higher in winter as compared to summer season. Heavy metals (Cr, Ni and Mn) in water samples were found higher than that of standard limit in both the seasons. Disposal of industrial wastewater was found to be the main causes for the pollution of water. It is suggested that disposal of wastewater should be treated properly before discharge into water bodies. Consequently, water will be contaminants free for community people and aquatic species that will help to protect of sustainable livelihood.

The paper presents experience of developing and maintaining a system of radioecological monitoring of freshwater ecosystems in the vicinity of Rooppur Nuclear Power Plant (Bangladesh). Components of freshwater ecosystems in the zone of NPP impact are both very informative for determining the environmental state and very important for conducting economic activities. Therefore, the issue of assessing and predicting quality of freshwater ecosystems in the vicinity of NPP is relevant for ensuring radiation and environmental safety. During the studies, we developed a detailed monitoring program; selected observation points for the state of surface water and groundwater at different distances from Rooppur NPP; determined monitoring objects (water, bottom sediments, higher aquatic vegetation, and fish), list of parameters to be studied, observation regulation, methods, and regulatory and technical support. Among the indicators controlled we considered the following ones: physicochemical properties of water and bottom sediments; radionuclide content of components of freshwater ecosystems including natural (40K, 226Ra, and 232Th) and technogenic (90Sr, 137Cs, and 3H) radionuclides; and content of 19 heavy metals, as well as chemical pollutants. Monitoring studies were conducted in 2014–2017, considering climatic peculiarities of the region at different periods of the year. Radionuclides in environmental objects were determined by spectrometry and radiochemistry; heavy metals – by atomic absorption and plasma emission analysis methods. It was established that higher aquatic vegetation in the Padma River is found not in all seasons. In December, it was almost absent. The maximum species diversity was registered in June. Differences between surface water and groundwater in the vicinity of Rooppur NPP were distinguished for several physical and chemical characteristics. Values of drinking water total mineralization and hardness were higher than that of surface water by 2–3 times. This is due to Padma River water composition, the basis of which is meltwater and rainwater. Organic pollutants content in surface water and groundwater was below detection limits or at minimum ones (benzopyrene – less than 0.01 μg·L−1; phenols – 1.3–3.5 μg·L−1; and petroleum products – 0.01–0.043 mg·L−1). Activity concentration of 137Cs in Padma River water did not exceed 0.18 Bq·L−1 (with a mean of 0.07 Bq·L−1) during the observation period. The content of 90Sr was 0.02–0.12 Bq·L−1, and the concentration of 3H varied in the range of 0.8–2.1 Bq·L−1. Mean specific activity of 90Sr in bottom sediments was 0.5–1.8 Bq·kg−1, and 137Cs – 0.8–2.1 Bq·kg−1. Specific activity of 3H in bottom sediments was less than 3 Bq·kg−1, except for 3 samples in 2017 (12–30 Bq·kg−1), which was most likely due to a local pollution. Specific activity of 90Sr in higher aquatic vegetation was 0.4–3.9 Bq·kg−1, and 137Cs – 0.4–1.0 Bq·kg−1. In drinking water, activity concentrations of radionuclides were as follows: 137Cs – 0.03–0.27 Bq·L−1; 90Sr – 0.01–0.16 Bq·L−1; 3H – 0.4–1.2 Bq·L−1. Specific activity of 90Sr in fish was 0.02–1.6 Bq·kg−1.The content of 137Cs in fish was 0.26–0.3 Bq·kg−1. Analysis of monitoring data on heavy metal levels in components of freshwater ecosystems in the vicinity of Rooppur NPP showed that for a number of elements their increased concentrations were recorded, most of which belong to monsoon season. In Padma River surface water, a repeating increase in As, Cd, Mn, and Al concentrations was noted, and in bottom sediments – an increase in As, Cd, Ni, Co, and Zn content, which was associated with anthropogenic impact and increasing runoff of pollutants during monsoon rains. Repeatedly increased As and Mn concentrations were noted in drinking water of Rooppur NPP 30-km zone. In separate samples, there was an increase in Fe and Al content. This might be due to both natural peculiarities of the region (relatively high As content in aquifers) and the state of water supply systems. Obtained results and developed network of radioecological monitoring of freshwater ecosystems would make it possible to register a change in the situation and to identify impact of Rooppur NPP operation on human population and the environment.
