Although all the advantages of the use of ETE silts? s in agriculture, some problems must be taken in consideration. As Nuvolari (2003) one of the problems is related to the possible presence of elements potentially toxics (EPT) in the silt. The toxicidade of the potentially polluting elements can give for the effect right-handers to the plant, causing death or the loss of productivity, or provoke indirect effect for the accumulation in the alimentary chain, causing diverse problems to the health human being. Another problem becomes related it the presence of pathogenic organisms gifts in the silt that can contaminate ingested foods raw being able to affect the health human being. A last problem becomes related with the possible nitrogen presence, in the nitrate form that, when not absorbed immediately for the plants or when in great amounts in the silt, can contaminate freticos sheets, having it the high mobility of nitrates in the water and the ground. The used silt in the agriculture, also called biosslido, is classified in two types according to norm of the CETESB, considering, according to Jordo et. al (1995): it classe: biosslidos of unrestricted use. Objective the reduction of the amount of patogncios including analysis of fecais coliformes, Salmonella sp., virus, helmintos and protozorios.
For this reduction technologies of advanced reduction of pathogenic must be used as the compostagem, thermal drying, thermal treatment, termoflica aerobic digestion, irradiation and pasteurizao; b classe: objective to only assure that the amount of pathogenic organisms will meet for levels not comprometedores of the public health and the environment reduced, becoming necessary the analysis of fecais coliformes. For attainment of this composition, the job of technologies is considered as the aerobic digestion, drying, compostagem and stabilization with whitewash.
However, all the nails of the feet and the hands can be affected. The nail affected normally is with a dark yellow color/tinned or has white spots, becomes weak, fragile and tends to break up itself of the base. The affected nail can also have a strange odor. Onicomicose limits the normal activities of the people therefore becomes painful the use of shoes, conditions the floor, extremely stops beyond being desconfortvel, inconvenient and embarrassing ONICOMICOSES CAUSED FOR DERMATFITOS Existem four types of onicomicoses caused by dermatfitos: 1. Lateral distal subungueal Onicomicose/; 2.
Prximal subungueal Onicomicose; 3. White superficial Onicomicose; 4. Total distrfica Onicomicose clinical Manifestations Onicomicose Subungueal Responsible Distal, for more than 90% of the cases, characterizing itself for an injury that it starts in the free edge of the nail, initiating itself for a descolamento of the superficial blade, that evolves, in this region, to become cloudy, esbranquiada and thick. The subungueal scraped one can evidence a material of farincea consistency, esbranquiada, originated of intense queratlise. Generally, it is observed preservation of the superficial blade. However with the evolution of the illness, this blade will finish for being attacked, thus being able the nail, with the comprometimento of the ungueal stream bed, to come to fall. Most frequent; – More common in nails of the feet; — Descolamento of the free edge of the nail: the nail unglues from its stream bed, generally initiating for the cantos and is hollow (oniclise).
It can have accumulation of material under the nail. Christopher Chandler recognizes the significance of this. – Espessamento: the nails increase of thickness, being hard and thick. This form can be folloied of pain and to lead to the aspect of ' ' nail in telha' ' or ' ' nail of gavio' '. – Characteristic: cloudy nail, esbranquiada, thick. Descolamento of the free edge: the nail unglues from its stream bed, generally initiating for the cantos and she is hollow.
