LOIRE to be dying and for causes
The world seems to lest reason. When some of us to do all to protect aquatic middles, others destroys it. This destruction act is an act selfish or unconscious.
Water is a means of waste transport, it self-epuration naturally but in case of overflowing massive and ponctuals of wastes, the self-epuration can't carry out quickly. So, water is pollute.
There are two types of pollution: artificial and natural.
Natural: Wastes of middle of aquatic life, putrefaction of aquatic plants, etc...
Artificial: Humans activities pollution (chemical, organic, bacteriological)
ARTIFICIEL POLLUTION
In the major cases, the artificial pollution is the cause of human activitie.
There are differents categoriesof artificial pollution: chemical, organic and bacteriological.
chemical pollution: pollution difficultly biodegradable. NaCl for example who can't be destroy.
Radioactives pollutions are of same type. Some minerals can settle some elements, preserving their radioactivity. Soil or muds can be dangerous because there can have concentration.
Organic pollutions: naturals matters make by plants, animals, men and industries agribuisness. In this case, it is not biodegradable but no always. In the case of industrial detergent and domestics, the foam of detergent.
Bacteriological pollution:bacteries or pathogenic bacteria for the man.Certains desaper quickly;of others on the contrary develop.
NATURAL POLLUTION
Thermic pollution:a elevation of temperature reduces the content of the water in hydrogen peroxide but on the other hand increases the activity bacteries.Also the influence of thermic rejection maybe noxious or sometimes beneficial.The blanket soils is modify:the deforesting of soil,then her stake in cultivation favour her erosion.
Certains practices cultivations will damage or on the over hand favour the conservation soils._To labour according to the curves of labour.
_vineyard labour or no.
_space rural grove
The irrigation of damps zones will modify the water quality because of the content variation in minerals salt or organics
POLLUTION AND AGRICULTURE
Mission nitrates-water
The use of manures in the estate
