Nitrate pollution

Severe water problems are also faced in southeast Asia. For example, Bangladesh and adjacent parts of India suffer from arsenic contamination of groundwater. Specifically, arsenic poisoning of groundwater has affected more than 50% of the total area of Bangladesh. The gradual introduction of arsenic inyo the food chain is more than a possibility. Nitrate pollution is also a problem in these areas. 

In conclusion, nitrates pollution of rural domestic wells continues to represent an important concern for the human and enviromnent health in the Dolj County. The occurrence of new cases of infant methemoglobinemia in these rural communities suggests serious deficiencies in the conditions of life in villages and in the sanitary educational status of their inhabitants.

In a few cases, nitrogen pollution affects humans directly. Nitrates pollute groundwater supplies in many farming areas. Nitrogen oxides in the air turn into ozone, harming both vulnerable humans and plant life.

It was found out that for selected area of the river flow there is no full mix of nitrate pollutant up to receipt of homogeneous solution. The flow consists of stream with high and low content of pollutant.

There are at least two ways in which nitrate pollution of water is known or suspected to be a threat to health. Firstly, the build-up of stable nitrate compounds in the bloodstream reduces its oxygen-carrying capacity. Infants under one year of age are at most risk. Consequently, a limit of 50 mg h of nitrate (NO3) has been recommended by the World Health Organisation (Anon, 1993). Secondly, the possible combination of nitrates and amines through the action of bacteria in the digestive tract results in the formation of potentially carcinogenic nitrosamines.

Nitrate pollution of some surface waters and groundwater has become a major problem in some agricultural areas (see Chapter 7). Although fertilizers have been implicated in such pollution, there is evidence that feedlots are a major source of nitrate pollution. The growth of livestock populations and the concentration of livestock in feedlots have aggravated the problem. Such concentrations of cattle, coupled with the fact that a steer produces approximately 18 times as much waste... 

IODINE AND GOITRE IN THE NETHERLANDS A ROLE FOR NITRATE POLLUTION ... 

One of the modern problems in the Netherlands is the increase in nitrate pollution. Due to the tremendous increase in the use of manure and fertilizer the concentration of nitrate in agricultural soil and surface water in different regions of the Netherlands have largely increased. As a consequence high concentrations of nitrate can be found often in many vegetables which are consumed in high amounts by the Dutch population, such as lettuce, endive, purslane, turnip-tops, celery.
