The Problem about soil contamination is that humans can be exposed to it in multiple of ways, however, one of the most common method is through something that all have to do for their own survival: eating. Of course, anyone has the choice of eating what is considered to be “healthy,” such as fruits and vegetables, or “unhealthy,” potato crisps or candies. However, consider the crops that are shipped in from other parts of the States or parts of the world that are supposedly to be “healthy” are actually one of the way to be exposed to soil contaminants? Yes, however it also depends on the manner of how the farm irrigate their crops.
So why does consuming from the more poorly irrigated soils are considered to be harmful to the human body? First of all, for those soils that are exposed to heavy metals, such as lead, cadmium, mercury and arsenic, are considered to be hazardous to humans because of their toxicity that could result in poisoning the person and lead to a disease. Take cadmium, for example, this element alone is toxic to the kidney. It also cause bone demineralization, either through direct bone damage or indirectly as a result of renal dysfunction. This is only one of the elements that causes harm to the body. Certainly, eating the plants that are grown on contaminated soils are unhealthy, however it is also important to know that sometimes when people do eat these vegetables the soil, or dirt, are also ingested by people as well. These soils are surely more concentrated in the harmful metals than eating the vegetables itself.
From what is said, eating vegetables and fruits can be harmful to yourselves in one way it seems. It is important to know that the crops that are grown have to pass through Although, do not fret too much about the vegetables and fruits that are sitting in your kitchen: what a person can possibly do to lower the harm to themselves from ingesting these heavy-metals is to wash the fruits and vegetables thoroughly, making sure that there are no dirt on it before consumption -- best possible -- and to be cautious of where the items are from, possibly even do research on them.
