Title: An Assessment of Environmental Concerns in Leather Industry Case study Khartoum North Tanneries
Author: Ahmed, Sara Awad El Kareem
Abstract: The objective of the research is to study the pollution due to tanneries with special concentration within Khartoum North (Bahry) Industrial area, to propose methods and means for prevention of pollution and to suggest some mitigation measures to save the surrounding environment from further degradation. The method employed include an analysis of not less than 1500 ml samples of liquid waste, representing those emerging from the tannery as well as those present in the settling tanks prior to their final discharge to the municipality sewage network, samples were taken during day hours in October 2014, It is important to mention that those wastes are normally discharged without a prior treatment or without determining their content in fugitive gases normally emitted inside the tannery and its surrounding, It is also important to say that solid wastes of this industry are not taken into consideration. The results of the study prove that tannery industry is one of the major environmental pollutants resulting from a none scientific removal of those wastes. It was found that the concentration of the known major pollutant from these tanneries are far beyond the allowable limits, namely Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD) and Total Chromium are about 28000, 2520 and 5.9 mg/l respectively compared to 75 for COD, 50 for BOD and 0.5mg/l for Total Chromium as per the permitted standards of Sudanese Standard and Metrology Organization (SSMO). In addition to that solid waste is normally collected with municipal and garbage waste without any treatment or recycling. However, gases emitted from tannery were found within the permissible limits and not exceeding 2.00ppm for NH3 and zero level for CO compared to 20ppm for NH3 and 500ppm for CO as per the permitted standards of SSMO. It is considered that the non treatment of those waste comprise a major environmental pollution causing negative impacts on human, health, soil and plants. It is recommended that some methods for mitigating those negative impacts through following cleaner production concepts and Standard Operating procedures (SOPs).
