Summary
[edit]
| Description |
Français : Exemple de déchet dangereux en quantité dispersée.
Verre cassé (ici, il s’agit d’une bouteille de bière écrasée par un autobus, sur une route urbaine, devant un abri bus). Questions pour l’écotoxicologue : Que deviennent ces minuscules morceaux de verre très coupants, quand ils sont emportés par la pluie vers les cours d’eau ? Que deviennent-ils après avoir été emportés par le vent ? Restent-ils dangereux ? et combien de temps ? quand ils se retrouvent dans les tonnes de poussières récoltées par les balayeuses municipales . De nombreux fragments sont emportés par les égouts vers des station d’épuration ou des systèmes de récupération des graisses et graviers.. Que deviennent-ils ? Des boues d’épuration contenant du verre pilé ou cassé pourront-elles être épandues sur des champs cultivés ? Que se passe-t-il quand un vers de terre ingère de tels fragments, et qu’un faisan mange ce vers de terre, etc. .English: Example of hazardous waste in dispersed quantity.
Broken glass (here it is a green vine bottle crushed by cars, on an urban road, in Lille (northern France). Questions for the ecotoxicologist : What happens to these tiny pieces of very sharp glass when they are carried away by the rain to the streams? What happens after they have been carried away by the wind? Are they still dangerous? And how long ? when they are (by tons) collected in dust harvested by the municipal sweepers. Many fragments are carried by sewers to sewage treatment plants or grease and gravel recovery systems. What happens to them? Will sewage sludge containing crushed or broken glass be spread on cultivated fields? What happens when an earthworm ingests such fragments, and a pheasant eats this earthworm, etc. . |
