“…Cadmium levels do not also differed significantly in all the sampling sites. Manjushree et al, (2013 Simul-Bhuyan andShafmentaliqul-Islam (2017);Mohammed et al, (2017) obtained similar Cd levels in tannery effluents and treatment efficiency of 33.25%. 0.07mg/L and 0.081mg/L were reported by (Sahuet al, 2007;Amanial, 2015).…”

The evaluation of physicochemical parameters and some heavy metals was carried out from six different tannery companies at the industrial areas of Challawa and Sharada, using standard procedures. Temperature, pH, conductivity and total dissolved solids(TDS) were determined using portable digital hand logging meter. The sulphate, phosphate, nitrate, arsenic contents were determined using UV Spectrophotometer, while chloride, dissolved oxygen (DO) and biochemical oxygen demand (BOD) contents were determined using titrimetric method, and the heavy metals by atomic absorption spectrometry. The mean temperature of the water ranged from 36.00 – 39.670C, pH: 2.63 – 9.33, conductivity: 336.33 – 12351.67μS/cm, TDS: 166.73 – 6017.67mg/L, sulphate: 114.00 – 466.67mg/L, phosphate: 0.29 – 12.80mg/L, chloride: 58.66 – 1577.87mg/L, nitrate: 6.03 - 33.43mg/L, DO: 2.60 – 21.27mg/L and BOD: 0.77 – 12.33mg//L. Water samples from the tannery effluents contained higher levels for both physicochemical parameters and heavy metals in untreated than treated. Cadmium and nickel were within the WHO limit for both treated and untreated while arsenic was within the limit for only treated effluent. Chromium and lead were above the WHO limit for both treated and untreated effluent. The parameters studied showed variations within the tannery companies and this may affect the Challawariver where this effluent is discharged which can have long term health effect on the aquatic animals and humans that depend on the river water for their daily activities.

“…The results showed that the soil was significantly enriched with titanium, manganese, zinc, lead, arsenic, iron, strontium and antimony as a result of mineral activity. 50 Salman et al evaluated heavy metal contamination in Arabi farms in Elbor, Egypt. Soil contamination with these metals was calculated using pollution factors, degree of pollution, PLI, environmental risk factor (Er), potential environmental risk index and land accumulation index.…”

Background: The potentially toxic elements (PTEs) are one of the most dangerous pollutants in the environment. In this study, the elements namely cadmium, lead, chromium, nickel, copper and zinc were investigated in the soil. Methods: In this study, 144 composite samples were randomly prepared from surface soils in a depth of 10 cm in the cities of Shushtar and Dezful. Soil sampling was performed in 12 stations in Shushtar and Dezful. The PTEs were determined by ICP Varian 710-ES device. Results: The pattern of accumulation of PTEs was as Cu>Pb>Cd>Zn>Ni>Cr in Dezful. In Shushtar, the accumulation of metals in the soil was as Cu>Pb>Cd>Ni>Zn>Cr. The concentration of Ni and Cr in the surface soils of Shushtar was higher than Dezful. The Ecological risk of Cd in the surface soils of Dezful and Shushtar was higher than other PTEs. The most important risk factor for carcinogenicity was related to Cr (3.15×10-7) in children. Hazard quotient (HQ) value of studied PTEs for adults and children were obtained by ingestion, inhalation, and dermal contact absorption of less than 1. Conclusion: According to the results, the PTEs of Cd, Pb and Cu caused high pollution in the soils of Shushtar and Dezful, which is due to agricultural, industrial and urban activities in these areas. In general, the metals Cr, Zn and Ni slightly contaminated the soil. Also, the ecological risk of PTEs showed that the highest effects on soil was related to Cd and Pb metals.

“…The presence of heavy metals in the aquatic environment is of major concern because of their heavy toxicity, and bio-accumulating tendency in the biota. Pollution by heavy metals is a threat to human life and the entire environment as well as the wetland ecosystem [37][38][39]. Contaminated water is not suitable for household uses and possibly hazardous to many aquatic animals and human health.…”

In recent times, Bangladesh has experienced increased environmental degradation in general, particularly industrial pollution. The effect of industrial pollution is huge and the country is affected badly in a socio-economic way. This article emphasizes the problem of industrial pollution with regard to the present status of the environment in Bangladesh. It contains a summary of the country’s major environmental problems, a compilation of varied information on industrial pollution, and its effects. In the end, this article gives a silver lining on the magnitude of the problem and strategies for handling industrial waste management in an environment-friendly way.
