  An analysis of photochemical smog pollution in Jakarta was attempted using data from the existing air quality monitoring stations. Ground-level ozone potential is high in Jakarta due to the high traffic emissions of ozone precursors and the favorable surface meteorological conditions. Despite the frequent missing data during the 1996-1999 monitoring, which resulted in lower ozone values, ozone episodes were significantly recorded in 1997-1998. The number of hours on which ozone concentrations exceed the 1-hour standard (100 ppb) at an ambient station located in Kelapa Gading (10 km northeast of city center) was 186 hrs in 1997 and 571 hrs in 1998. El Niño phenomenon in 1997-1998 had affected the local meteorology leading to more favorable conditions for photochemical production of ozone. The annual ozone averages in ambient stations located off the city center have exceeded the 1-year standard limit (15 ppb). Although the annual average and 95-percentile values indicated an increasing trend from 1996 to 1998, the trend remains to be seen in the future as more complete data could be expected from the new monitoring system. The number of hours on which ozone exceed the 1-hour standard and the annual average tend to be increasing since 2001 to 2002 in all 3 newly operated stations. The seasonal variations of ozone indicate that ozone level is highest in the dry season (September-November) and is lowest in the wet season (December-March). Correlation between ozone level and meteorological attributes (solar radiation, relative humidity and temperature) was significant at 0.01 confidence level. The diurnal cycle of ozone and its precursors is clearly shown and is typical for polluted urban areas. Improvement of the database of air quality monitoring is very critical for Jakarta. Through better database management, the development and monitoring of cost-effective air pollution control strategy can be made.

  Sylhet-Sunamgonj region is one of the most important freshwater fish producing areas of Bangladesh. A huge amount of fish is produced in these regions to support local consumption and also export to other countries. The caught fish are not adequately taken care off during harvest and post-harvest handling. So, a serious loss in wet fish occurs. The present study has determined the extent of quality loss in fish value chain in Sylhet-Sunamgonj regions with a view to minimize such losses. Extent of loss in wet fish quality at the stakeholder level during transportation like fish farmer, arotder (commission agent), wholesaler and retailer was assessed. Two big landing centers, one big wholesale markets and one retail market of Sylhet-Sunamgonj region were studied. Data were collected through questionnaire interview along with traveling throughout the distribution channel. A sensory method was used to assess the quality of wet fish. Insufficient icing, mishandling of fish, non-insulated carrying container and lack of awareness were found to be the reasons for the quick quality loss of wet fish in these regions.

  The present study was designed to know the landing and distribution pathways of fish and types and nature of stakeholders involved in fish distribution chain in Bangladesh. A total of 237 fish landing centers and 5440 markets were detected. The number of landing center and market were highest in Chittagong and Dhaka division respectively. Stakeholders in fish distribution, viz., arotdars, paikers and retailers were found to be 6219, 39506 and 122922, respectively. A 84.71% of the landing centers were found to be operated year round while 15.29% were seasonal. The major fish production zones and major gateways of the country where inland capture and culture and marine capture fish landed were identified. In any locality 62.83% of the landed fish were transported within 100 km area and 5.73% of fish were transported beyond 500 km. The quantity of fish harvested from river, beel, Kaptai lake floodplain, pond, baor, coastal area/sea and shrimp/prawn farm were 5.25, 4.41, 0.13, 35.03, 38.22, 0.23, 10.93 and 5.80%, respectively. The common constraints identified were lack of adequate infrastructure facilities in the landing center and market, unhygienic environment, influence of middlemen, money lending at high rate etc. For the betterment of fish landing and distribution, appropriate authority should pay proper attention so that both quality and fair price are ensured.
