The Law

Les Abattes (Le Locle, Canton Neuchâtel) is an ancient dump contaminated by metals, like thousands of others in Switzerland,which, according to the law, does not require a reclaiming. Local trees have been grown on this site and data have been collected for 15 years between 1991 and 2005. Lessons grown from this experience are mixed. The plantation has stabilised the soil physically and immobilised the metals more rapidly than natural pioneer plants would. However growing trees have not been able to extract enough metals from soil. The risk of a diffuse metal contamination of surface water and food chain is still present. Therefore reforestation of low-contaminated sites has to be seen as a temporary solution requiring a continuous supervision in a longterm. At best it could provide timber under certain conditions. It is recommended to clearly indicate these constraints in the forest guiding plans which are now being elaborated.

This study was carried out in order to assess the effect of industrial effluents on the surface water and sediment around BSCIC industrial area, Narayanganj. Different parameters such as TDS, DO, pH, EC, Turbidity, BOD, COD, and heavy metals such as Pb, Zn, Cd, Mn, Cr and Ni were investigated. The results showed that, different industries inside the BSCIC area discharge effluents composed of various chemicals at considerably higher levels compared to pollution limits of inland surface water standard given by DoE. Significantly higher levels of EC (3540 ?S/cm), TDS (3862 mg/l), BOD (143.71 mg/l) and COD (396.30 mg/l) were found in the water. Also a higher level of heavy metals along with high pH was found both for the water and sediment around the BSCIC area. A significant correlation was found between the pH, EC and heavy metal concentration of the collected water samples. The above findings point out that the water around the studied area is quite polluted by the industrial activities of the BSCIC area and malicious for surrounding environment.Bangladesh J. Sci.

Main Thing

Environmental pollution around the world in the last 10 years has continued to increase with increasing industrial growth. Environmental pollution has reduced the availability of clean water. Clean water is the main thing for all living things on this earth. Therefore, environmental pollution that occurs in the clean water crisis must be handled as soon as possible and reduced by various effective policies. The main focus of this research is to analyze heavy metal pollution on the surface of the water, clean water, and sediments caused by industrial activities. This research is a field study by taking samples directly at the location and then analyzing them in the laboratory. The results of the analysis showed that the highest heavy metal Fe on the water surface was found in Bireuen Regency by 0.28% compared to Lhokseumawe City with 0.0029% and Aceh Utara 0.0029%. Meanwhile, the highest heavy metals contained in clean water were recorded in Bireuen and Lhokseumawe City at 0.007% and 0.0064%, respectively. The results of the heavy metal analysis in the highest sediment were found in North Aceh at 42.93% compared to 8.02% and 18.12% for Bireuen and Lhokseumawe. Overall, the analysis carried out in this study shows that the surface water, clean water, and sediments have been contaminated by heavy metals. Meanwhile, the quality standard for surface water is 0.3 mg/l, net ai is 1.0 mg/l, and sediment is 20bj.
