Rising soil pollution has recently emerged as a significant global issue as a result of increased industrialization, urbanization, and inadequate waste management. In Rampal Upazila, soil contamination with heavy metals resulted in a significant deterioration of quality of life and life expectancy, so the study's goal is to appraise the level of heavy metal contamination in soil samples. Inductively coupled plasma−optical emission spectrometry was used to identify 13 heavy metals (Al, Na, Cr, Co, Cu, Fe, Mg, Mn, Ni, Pb, Ca, Zn, and K) from 17 soil samples that were collected at random from Rampal. Enrichment factor (EF), geo-accumulation index (I geo ), contamination factor (CF), pollution load index, elemental fractionation, and potential ecological risk analysis were used to evaluate the level of pollution and sources of metal. The average concentration of heavy metals implies that they are below in the permissible limit except for Pb. Environmental indices also showed the same result for Pb. The ecological risk index (RI) for six elements�Mn, Zn, Cr, Fe, Cu, and Pb�is 26.575. For investigating the behavior and origin of elements, multivariate statistical analysis was also applied. From the EF, Na, Cr, Fe, and Mg are in the anthropogenic region, and Al, Co, Cu, Mn, Ni, Ca, K, and Zn are minorly polluted, but Pb is highly contaminated in the Rampal area. The geo-accumulation index exhibits that Pb is slightly contaminated but others are not, while CF shows no contamination in this region. From the ecological RI, the value which is below 150 is called uncontaminated, which indicates that our studied area is ecologically free. There are various classifications of heavy metal contamination in the study area. Therefore, regular monitoring of soil pollution is required, and the public awareness needs to be raised to ensure a safe environment.

“…Iron, which is an essential element for the physiological functions in humans, may come from disintegrating metal parts, fertilizers, plant and animal wastes. Further, excess Cu and Zn in the environment may originate from transportation, liquid petroleum stations, battery, oil wastes, and oil leakage from boats and ships [14].

“…Tri-acid mixture (5:1:1; 70% HNO 3 , 70% H 2 SO 4 , and 65% HClO 4 ) was added with a set portion of the fish samples. Then, the solution was digested at 80°C for 30 minutes and analyzed on an AAS unit (Shimadzu model AA-7000) for the estimation of heavy metal contents (Mn, Fe, Cu, Zn, Pb, and Cd) [14].…”

Background: Fish is a source of nutrition; however, toxic substances and heavy metals may enter human body due to consuming contaminated fish. The aim of this study was to investigate the levels of heavy metals and DDTs in Liza parsia, a fish species, and assess the health risk of the contaminants in the fish samples. Methods: The extracted fish lipid was added with n-hexane and H2SO4 and was kept for long time. The upper organic part was collected for the analysis of DDTs by gas chromatography equipped with electron capture detector. The fish samples were homogenized by wet digestion method, and the heavy metal contents were analyzed, using an atomic absorption spectrophotometer. The health risks of the fish samples were assessed based on target hazard quotient and target cancer risk. Results: The pesticide contents of DDT, DDD, DDE and DDTs in the fish samples were 0.0414, 0.000253, 0.015 and 0.0567ng/g, respectively. Also, the mean concentrations of Mn, Fe, Cu and Zn were 35.42±10.05, 318.75±242.45, 41.67±4.78 and 281.25±5.42 mg/kg, respectively. Of note, the Cd and Pb contents were below the detection limits. The concentrations of other heavy metals were above the reference limits, which can cause various disease processes. Conclusion: The contents of four heavy metals and DDTs in the samples were above the limits. The main sources of these substances are likely due to human anthropogenic activities. Fish and other edible aquatic animals should be monitored regularly and the heavy metal levels be determined and declared to the public.

“…Heavy metal pollution is due to both natural and anthropogenic activities, such as smelting procedures, mining, excessive use of wastewater and fertilizers in agricultural fields and atmospheric deposition from vehicles and industries [16,23]. The presence of heavy metals in soil and groundwater is very dangerous because they are transferred to the food chain through vegetables, and long-term exposure to heavy metals causes various fetal diseases, mental illness, kidney failure, lung cancer, bone fractures, kidney dysfunction and hypertension [19,22,26].…”

The paper presents aspects regarding the water quality coming from drillings carried out in disused industrial areas, from the Brăila - Galați area. The studied parameters include the analysis of salts such as sulfates, nitrates, phosphates andcarbonates and the analysis of toxic compounds such as phenols, copper, lead, iron and aluminium. The experiments revealed the presence of some of the studied toxic substances. Finally, the results obtained and the classification of the studied indicators within the admissible limits were discussed and potential methods and techniques for depollution of drilling waters and soil in derelict industrial areas were proposed.
