Noise is the silent killer which has the ability to deteriorate the normal health condition of a
person. People working in heavy industries have a high risk of being affected by noise and this
phenomenon is unequivocally true for a country like Bangladesh. This paper identified the status
of noise levels, their ultimate impact on workers’ health, and noise reduction compliance in
Kalurghat Heavy Industrial Area (KHIA) of Chittagong. Eleven companies gave access to
collect data related to noise issues inside and outside of their factories. While the average inside
and outside noise levels were within the limit of 75 decibels (dBA), excessive noise at 89 dBA
from several source like dryer machines and generators are a concern. A semi structured
questionnaire was also used to collect data related to noise related compliance issue from the
respective personnel of the factories. The study found that most of the factories hardly use
physical mechanisms to control excessive noise.

Background: Economic evaluation of non-market goods is challenging and can’t be calculated using traditional
method. In this study, Travel Cost Method (TCM) was used to evaluate the economic value of Foy’s Lake of
Chittagong.
Methods: A total of 200 respondents from the visitor of this lake were interviewed on the basis of day of visit (week
day: 100, weekend: 100) using structured questionnaire. The collected data were analyzed using SPSS v 20 and R v
3.2.1
Findings: A multiple regression model was developed using the analysis which had a R2 value of 0.084. Family size and
Total cost of visitors were found significant with a p-value of 0.05. The estimated value for Foy’s Lake for 2014 was
worth 294165270 BDT (Bangladeshi Taka) (or 3792034.49 US $).
Applications: By applying the model, derived from this study can be used to assess the economic value by revealed
preference method of artificial lakes in this region.

Chittagong University is known as the cleanest public university in Bangladesh with its diversified natural beauty. But now a day's indiscriminate disposal of solid waste and lack of proper management, negative perceptions of people are threatening this sound environment of the campus. This study was conducted in Chittagong University Campus to identify the amount of Waste Generation and composition, also to understand peoples' perception in solid waste management. For this study a semi-structured questionnaire was prepared and a stratified random survey was conducted. Secondary data was collected from the Paharika Housing Society Office, Masterda Surya Sen Hall Office and Registers' Building. Total 30 household was surveyed during this study and 1.0 kg of solid wastes from each strata was collected, segregated and weighed. Solid waste generation per capita was 0.53 kg per day, per household 2.25 kg per day, total solid waste generation in south campus was 1127.86 kg per day. Composition of solid wastes in Chittagong University Campus were Vegetable and food wastes, Polythene and packaging materials, Paper-books and printing materials, Rags, Glass and Ceramics, Woods and leaves, Tin and cans and others which were comprised of 54.53 %, 16.45 %, 19.73 %, 4.2%, 1.9 %, 0.9 %, 0.5 % and 2.7 % respectively. Communal solid waste collection system is practiced in Paharika Housing Society and in other areas solid wastes are dumped in illegal unplanned sites nearby. An immediate step should be taken by the University authority to improvise the current condition through effective solid waste management.
