Environmental Management System (EMS) has become an important tool for organizations looking towards managing their environmental issues such as pollution, legal compliance and minimizing their environmental impacts. The present study was conducted to assess the environmental aspects and impact of selected scientific laboratories of Jahangirnagar University in Bangladesh with focus on the gap analysis for implementing EMS. Data and information were collected through frequent laboratory visits, focus group discussion, questionnaire survey and key informant interview. It was found that EMS was not implemented in the laboratories and the staffs and researchers of the university had very limited idea about EMS. Surface water, air and soil pollution; unsafe mixing and handling of hazardous materials and chemicals; unsustainable storage of chemicals and reagents; improper use of personal protective equipment found as the main environmental challenges in these laboratories. The maximum negative environmental impact occurred in the chemistry and botany laboratories, as large number of researchers’ here used high amount of chemicals and cultured media, while the minimum pollution was found in microbiology and environmental sciences laboratories. Although, the overall pollution levels were low, there were lots of gaps in introducing EMS. Therefore, initiatives should be taken.

The efficiency of iron electrode based electrocoagulation (EC) technique at laboratory scale to remove lead (Pb) from battery industrial effluent in Bangladesh is investigated. Different combinations of voltage (15, 30 and 45), effluent pH (1, 3, 5, 7 and 9) and electrolysis time (15, 30, 45 and 60 minutes) at the EC reactor was examined for searching the ideal operating conditions of maximum lead removal. Initial battery effluent pH of 3, electro coagulating at 30 V for 15 minutes would be the optimum conditions for treatment where 99.9% Pb removal was achieved. Treated effluent quality was compared with national environmental standard to discharge into surface water bodies and found physico-chemical parameters (TDS, TSS, DO and pH) were within prescribed limit except electrical conductivity.Journal of Bangladesh Academy of Sciences, Vol. 39, No. 2, 125-134, 2015

Background: Inguinal hernia is a common problem and its repair is one of the most commonly performed procedures in general surgical practice. Several methods have been developed including Lichtenstein’s repair. Among these Lichtenstein’s repair has been standard technique for last few decades. In recent time a new procedure “no mesh Desarda hernia repair” has emerged as a recognized operative method for inguinal hernia repair. Objectives: This study was conducted to evaluate the outcome of Desarda technique in repairing inguinal hernia. Methods: This was a single centered descriptive study to see the outcome of inguinal hernia repair by Desarda technique in both elective and emergency surgery carried out in the Dept. of Surgery, Sher-E-Bangla Medical College Hospital, Barisal from August, 2015 to July, 2016. Results: A total of 100 patients underwent Desarda repair for inguinal hernia including primary/recurrent and elective/ emergency cases. Variables includes age, type of surgery, operating time, post-operative complications, post-operative pain, post-operative hospital stay, cost of the procedure, chronic groin pain and any early recurrence. Mean age of patient was 48.9±9.07 years. Mean operating time was 43.72±9.64mins. Majority (54%) of the patient experienced mild post-operative pain on first day, measured in VAS score. Ten percent of patients developed different post-operative complications like wound infection (2%), seroma formation (1%) and scrotaledema (7%). Conclusion: In this study, it is revealed that no mesh Desarda repair for inguinal hernia was associated with less operating time, less post-operative pain, less post-operative complications, short hospital stay, zero recurrence rate, no chronic groin pain and performed in emergency cases also. So, it is safe and most reliable technique for all type of inguinal hernia surgery.
