The river pollution has also hit the local fishermen hard. This paper analyzes the different types of environmental pollution and associated health hazard in Bangladesh. It is the by-product of the development of civilization and in fact a price for the progress. Coupled with these, the high upland discharge with a heavy sediment load, severe tidal activity at the head of the Bay of Bengal, piling up of water at the coast during monsoon are some of the extreme conditions including rapid morphological instability of the area. Risk: Low 1-3 Moderate 4-6 High 7-10 Very high above 10 As it is now known that even low levels of air pollution can trigger discomfort for the sensitive population, the index has been developed as a continuum: The higher the number, the greater the health risk and need to take precautions. The tertiary hills are situated in Rangamati, Bandarban, Khagrachari, Cox's Bazar, Chittagong, Sylhet, Maulvi Bazar and Habiganj districts. Cadmium Cd Growth retardation, diarrhea, bone deformation, kidney damage, anemia, injury of central nervous system, hypertension, injury to lever.
It is an issue that troubles us economically, physically and everyday of our lives. The pH varies from 6. At present, Dhaka city alone generates about 5000 million tons of solid wastes per day. The fishermen of Bangladesh are traditionally among the poorest of the rural dwellers. In a similar way untreated domestic wastes are also thrown into the river or the Bay affecting local fisheries adversely with fish catch diminishing gradually on account of oxygen depletion. There are pollutions of air, water, soil, noise and radioactive wastes.
Cities also encourage or discourage certain types of industrial land use according to future development strategies. The outflow is second only to that of the Amazon river system in South America. Challenges of climate change risk reduction and better governance Bangladesh has emerged as one of the most vulnerable countries in the world confronting imparts of climate change. Elements without health based guideline values such as aluminium Al, 95% and chloride Cl, 5. Pollution is now everywhere in Dhaka and symptom is very clear to us. The estimation for stable materials solid waste production for Dhaka has varied from 3000 — 4500 metric tons per day.
The powerful groups should not get any privilege in destroying environment. We should stop using of all types of fire weapons. The pressure of a huge population of about 130 million on a very limited resource base has, perhaps, surpassed the country's carrying capacity in terms of both the source and sink functions of the environment. With the process of industrialization comes our social change, economic development, and technological innovation. Bangladesh has many priorities, most of them are competing and yet complementary.
Here the land is embanked to contain salt-water ponds for a shrimp cash-crop. They are working in hard-to-reach areas with the poor, women and marginal communities with pro-poor approaches. Soil or Land Pollution Air pollution : Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. Pollution is the introduction of contaminants into the natural environment that cause adverse change. The sources that I used are:.
The five most vulnerable countries to ocean acidification are — Japan ranking first in the analysis, followed by France, the United Kingdom, the Netherlands and Australia. Many universities have introduced various curriculum and projects on environmental issue. When solid waste discharged through sewage system causes several soil and water borne disease. My topic is all about pollution. Air pollution by Chemical Industries: Air pollution in capital city Dhaka has gone higher than Mexico City and Mumbai killing thousands prematurely each year. In the hot season, the average maximum temperature is 34°C and the average minimum is 21°C. More importantly, bioaccumulation of metals in fish, crabs and other edible aquatic species, may cause health problems to enter the food chain.
This area functions both as terrestrial and aquatic ecosystems ensemble. There is already a natural seasonal fluctuation of rising levels of salt water. The sediment load, carried by streams mostly consisting of coarse sand, is deposited on the land, just as the silts fill up river beds, inducing flash floods. Most plants require a soil substrate to provide water and nutrients, and whether we farm the plants directly or consume animals that feed on the plants, this means that we don't eat without soil. Scientists are concerned with a fact that, everybody anticipates sea-level-rise impact and associated climate change impact on Bangladesh coastal areas. The 197 Au n,gamma 198 Au monitor reaction induced in a high-purity gold foil was used to determine the effective neutron beam intensity.
Most industries are dependent on extracting minerals from the Earth. This reason only makes up a fraction of why we need to save this incredible animal. Developing educational materials or exhibits related to environmental system in Bangla have received priority consideration from many private and public organisations including the Disaster Management Bureau. Improper land use and mode of farming, jhum cultivation for that matter, leading to massive erosion and flash floods in general have made the north and southeastern hill areas vulnerable to both physical and cultural interventions. Soil erosion is the wearing away of soil. The death rate in the year 1996 mainly due to environmental pollution is as follows.
