“…DWASA mainly relies on groundwater (70% of the total supply) and the distribution takes place through the overhead tanks in different parts of the study area. Surface water is used in the monsoon period while achievement of the desired quality of drinking water cannot be possible since heavy contamination from heavy metals and organic materials heavily degraded the quality of water in the source areas [ 46 ]. Groundwater quality in the Mirpur area is also at risk in recent years, since the indication of mixing of pollutants carried by surface water has been reported in the area [ 36 ].…”

“…For metal analysis, the digestion process involved taking a 100 mL water sample, adding 2 mL of concentrated HNO 3 (67-70%), and then evaporating the mixture to reduce the volume to 40 mL. The sample was subsequently filtered using filter paper (Whatman 42 μm) after being diluted to the appropriate volume with distilled water [44][45][46][47].…”

Saltwater intrusion in the coastal areas of Bangladesh is a prevalent phenomenon. However, it is not conducive to activities such as irrigation, navigation, fish spawning and shelter, and industrial usage. The present study analyzed 45 water samples collected from 15 locations in coastal areas during three seasons: monsoon, pre-monsoon, and post-monsoon. The aim was to comprehend the seasonal variation in physicochemical parameters, including water temperature, pH, electrical conductivity (EC), salinity, total dissolved solids (TDS), hardness, and concentrations of Na+, K+, Mg2+, Ca2+, Fe2+, HCO3-, PO43-, SO42-, and Cl-. Additionally, parameters essential for agriculture, such as soluble sodium percentage (SSP), sodium absorption ratio (SAR), magnesium absorption ratio (MAR), residual sodium carbonate (RSC), Kelly’s ratio (KR), and permeability index (PI), were examined. Their respective values were found to be 63%, 16.83 mg/L, 34.92 mg/L, 145.44 mg/L, 1.28 mg/L, and 89.29%. The integrated water quality index was determined using entropy theory and principal component analysis (PCA). The resulting entropy water quality index (EWQI) and SAR of 49.56% and 63%, respectively, indicated that the samples are suitable for drinking but unsuitable for irrigation. These findings can assist policymakers in implementing the Bangladesh Deltaplan-2100, focusing on sustainable land management, fish cultivation, agricultural production, environmental preservation, water resource management, and environmental protection in the deltaic areas of Bangladesh. This research contributes to a deeper understanding of seasonal variations in the hydrochemistry and water quality of coastal rivers, aiding in the comprehension of salinity intrusion origins, mechanisms, and causes.

At part per billion (ppb) concentrations, heavy metals and pesticides both pose a significant health risk. Over-ingestion of pesticides and heavy metals in the environment may cause various diseases and effects on human life. So, a systematic analysis for detecting and removing pesticides and heavy metals from the environment is required. This review provides a comprehensive study of the several analytical methodologies employed in the quantification of heavy metal ions and agrochemicals in environmental samples. Furthermore, the detrimental impacts of these substances on both human health and plant life are also discussed. Moreover, a concise overview of the latest developments in the design of nanomaterial-based sensors, specifically focusing on colorimetric and electroanalytical approaches. These sensors are utilized for the detection and analysis of heavy metals and pesticides. In addition, the information garnered from the study will improved the capability to detect and remove contaminants from environmental samples.
