Abstract/ Executive Summary:

The study was carried out to assess the awareness of peoples on the impact of tannery waste disposal on environmental pollution of selected areas in Dhaka City. Data were collected by interviewing 300 peoples randomly of which 90 were labor, 60 livestock farmers, 60 fishermen and 90 were in local people in the study areas. Data were collected on age, education level, occupation, type of waste, color of waste, waste disposal time, environmental effect, human diseases, environmental pollution awareness, livestock diseases, livestock production and fisheries production. The findings revealed that about 34% respondents were illiterate. Both solid and liquid waste (56%) was come out from the tannery of which half of them were black in color. About 45% respondents were reported that the most environmental effect was bad smell to the surrounding areas. Survey result also showed different health problems such as skin diseases, itch, rash, cough, fever, diarrhea, headache, asthma, dizziness etc due to unplanned tannery waste disposal. The highest proportion (38%) of respondents had low environmental pollution awareness due to their education level. Livestock and poultry were died due to tannery waste indicated by 59% respondents. The livestock and fish production was low, reported by 48%. Education, occupation and type of waste had significant positive relationship where color of waste had no relationship with their environmental pollution awareness. The results of this study will be helpful to create people’s awareness on environmental pollution and their impact by tannery waste disposal.

Methodology:

The study was conducted at Hazaribagh area under Hazaribagh thana, Rayerbazar area under Mohammadpur thana and Islambag area under Lalbag thana in Dhaka city corporation. Hazaribagh area were selected purposefully because Hazaribagh area is covered 90% of total tannery where high amount of tannery waste are dispose on surrounding area specially the Buriganga river. The Rayerbazar area and the Islambag area were also selected because of those area also polluted by tannery waste. Primary data were used for this study. Sample survey was carried out for generating the required data. Three hundred respondents were interviewed from the study area and different information (secondary data) was collected with the help of Bangladesh bureau of statistics, Department of fisheries and Department of livestock. Three hundred respondents were randomly selected from three areas of which 90 were labors, 90 were local people, and 60 were fishermen and hatchery labor and 60 were livestock farmers. The maximum number of respondents from Hazaribagh selected for interview than other two areas. An interview schedule was prepared for collection of data from the respondents keeping the objectives of the study in mind. Both open and closed formed questions were included in the interview schedule. The questionnaire was prepared in Bengali for the respondents. Necessary additions, deletions, modifications and adjustments were made in the interview schedule on the basis of experience gained from the pretest. The pretest was helpful in identifying faulty questions and statements. The interview schedule was then finalized for collection of data. Personal observation and telephone interview were conducted for this study area. To build rapport and motivation in the interview situations, the researchers endeavored to provide conditions that maximized trust, maintained each respondent’s interest and minimize status difference. However, it is not possible to collect data from all labors, local people and fisherman and hatchery labors and livestock farmers in those areas due to their non-availability in the time of interview despite several attempts to contact them. Therefore the researcher had to collect data from 300 labor, local people, fisherman and hatchery labor and livestock farmers. Data were collected from January to May 2013. Data were collected on age, educational qualification, occupation, type of waste, color of waste, waste disposal time, environmental effect, human diseases, environmental pollution awareness, effect of livestock, diseases of livestock, effect on livestock production, effect of fisheries and effect on fisheries production, individual characteristics of the respondents were considered as independent variable and environmental pollution awareness was considered as dependent variable. The data were analyzed by the SPSS (Statistical Package for Social Science) program, using cross tab to find out the % of total data, mean, standard deviation and correlation between two or more variables.
