When animals are exposed to boron during pregnancy their offspring may suffer from birth defects or delayed development. When animals absorb large amounts of boron over a relatively long period of time through food or drinking water the male reproductive organs will be affected. Boron has been found in animal tissue, but it is not likely to accumulate. Plants absorb boron from the ground and through plant-consuming animals it can end up in food chains. Boron exposure may also occur from consumer products such as cosmetics and laundry products.
The concentrations of boron that are added by humans are smaller that the naturally added concentrations through natural weathering.īoron exposure through air and drinking water is not very likely to occur, but the risk of exposure to borate dust in the workplace does exist. Humans add boron by manufacturing glass, combusting coal, melting copper and through the addition of agricultural fertilizers. It may also occur in groundwater in very small amounts.
It takes 5 g of borc acid to make a person ill and 20 grams or more to put its life in danger.Įating fish or meat will not increase the boron concentrations in our bodies, as boron does not accumulate within the tissues of animals.īoron is an element that occurs in the environment mainly through natural processes.īoron occurs naturally in the environment due to the release into air, soil and water through weathering. When exposure to small amounts of boron takes place irritation of the nose, throat or eyes may occur. Boron can infect the stomach, liver, kidneys and brains and can eventually lead to death. When humans consume large amounts of boron-containing food, the boron concentrations in their bodies may rise to levels that can cause health problems. we have a regular daily intake of about 2 mg and about 18 mg in out body in total. Humans can be exposed to boron through fruit and vegetables, water, air and consumer products. Vulcanic spring waters sometime contains boric acids.īorates are mined in US, Tibet, Chile and Turkey, with world production being about 2 million tonnes per year. It is found combined in borax, boric acid, kernite, ulexite, colemanite and borates. Boron compound also came into the average home in the guise of food preservatives, expecialy for margarine and fish.īoron is not present in nature in elemental form. Boron filaments are used for advanced aerospace structures, due to their high-strength and light weight.Īn early use of borax was to make perborate, the beaching agent once widely used in household detergents. Boric acid is an important compound used in textile products.Ĭompounds of boron are used in organic synthesis, in the manufacture of a particular type of glasses, and as wood preservatives.
