Association between anemia and grading of arsenicosis

Chronic arsenic toxicity has been recognized as a typical form of arsenicosis which is defined by the experts of International Health Organization as a chronic health condition arising from prolonged ingestion of arsenic above the safe dose for at least six months, usually manifested by characteristic skin lesions of melanosis and keratosis, occurring alone or in combination, with or without the involvement of internal organs The present study evidences that the occurrence of skin manifestation varies form pigmentary changes, progressing to keratosis and even may lead to malignancy. The findings obtained obviously illustrate interlink between dynamics of severity of anemia and the promotion of the viable development of dermatological grading of arsenicosis

Unplanned urbanization: assessment through calculation of environmental degradation index

Urbanization is an inevitable phenomena for the country like Bangladesh. The push and pull factors help to migrate people from rural area to urban area. As a result haphazard and unplanned urbanization create environmental degradation. Survey data reveals that inadequate solid waste disposal services, lack of adequate public water supply, traffic congestion, water logging, air pollution, noise pollution, hill cutting are the main problems in the city area. Concentration of dust as well as SOx, NOx exceeded the allowable limit at the selected points. Groundwater level of Sylhet city has a considerable lowering over the last few decades. It has lowered from 3380 mm below ground in 1982 to 7880 mm below ground. Sylhet is located in highly seismic risk zone but most of the buildings and other structures in this area are constructed without considering earthquake risk. Environmental degradation index was calculated based on economical condition of the country
