EFFECTS OF POLLUTION BY INSECTICIDES CHEMICAL IN THE SOIL.
Soil is the place where by defect will stop much of the solid
and liquid waste of any human activity. The soil contamination is the
presence of chemical compounds or man-made alterations to the natural
environment of the soil. Everything that is not useful in any industrial
process, mining, urban, agricultural, etc. comes accumulating in the
ground without control throughout the years. Chemicals that can detect in
the soil can be since petroleum hydrocarbons, solvents, pesticides and
other heavy metals.
The
utilization of insecticides chemists realizes a pollution in the soil.
Agricultural activity has increased in recent
decades due to population increase, requiring a greater production for to
supply to all the population. This based mainly en the Earth fertilizer,
to increase to the zones of plantation and conservation of the existing
ones as well as pest control, by the increase of insects que reproduces
when having more food to the one than to attack.
These methods used for the control of plagues and
insects are very aggressive and devastating in the land, by the use of nitrates, phosphates, etc. that goes contaminated
the soil and this is because it is poured annually tons of fertilizers and
pesticides. Also the waters undergo the contamination, by the infiltration
of these products in the rivers and in water-bearing by the being used by
the man.
New
plagues of insects are made every year new insecticide adapted to.
Insecticides chlorinated organs can be kept for over ten
years in soils without decomposing. It has been shown that they can enter
the food chain concentrating in the fatty tissues of animals. There are
insecticides for fruit and vegetable that are biodegradable and do not
concentrate, but is associated in toxic effect it is trasmisor mechanism
of the nervous impulse in animals and people. Fungicides are used to
combat fungi, their chemical compound is the sulfur and copper. There are
herbicides that destroy any plant life impede their growth.
When
are used pesticides or herbicides it increases the pollution in the water.
The effects on the soil of all these pollutants can be
varied by time or climatic conditions, accelerating or decreasing their
solubility. But when it exceeds the capacity to cushion itself from nature
, what constitutes a time bomb that although chemistry does not produce
immediate effects can do it in a future.
