Au sud de Rodez, dès le début du Miocène, se met en place l’ébauche d’un nouveau réseau hydrographique et l’organisation d’un drainage est-ouest va supplanter le vieux modèle de l’Oligocène. Les drains se concentrent dans de larges couloirs, peu profonds en surface, de plateaux qu’il..

Rodelle – La Goudalie

Le Causse Comtal, au fil des prospections, livre peu à peu des éléments tangibles attestant d’une présence bien établie des néandertaliens sur notre territoire. Le site de La Goudalie présente un faciès Moustérien à denticulé qui pourrait se situer vers -115 000 ans. Au Nord de Rodez, sur la commune de Rodelle, le Causse Comtal est tranché net par le Dourdou, petit ruisseau à qui l’on doit également le creusement du canyon de Bozouls. Toute sa rive gauche est bordée de hautes falaises parfois..

Rodelle – Dolmen des Costes-Basses

Date de l'opération : 1991 (SU) Inventeur(s) : Bories Georges Les mégalithes du causse Comtal nous sont parvenus, pour beaucoup d'entre eux, dans un état de dégradation avancé. Le dolmen des Costes-Basses, situé près de Bezonnes, offrait des potentialités non négligeables pour tenter de comprendre les techniques de la construction de ce type de monument funéraire. Ce travail, entrepris par Georges Bories et son équipe, comportait deux phases indissociables : d'abord une étude archéologique p..

Laboratory simulation of captan residues degradation during apple processing

The degradation of captan residues during the processing of apple to sterilised purée was investigated using laboratory small-scale processing (125 °C for 20 min and pH 4.0). [14C]-cyclohexene ring-labelled captan was completely degraded, mainly to tetrahydrophthalimide (96.5%). Other minor products such as tetrahydrophthalic acid (0.3) and tetrahydrophthalamic acid (0.2) were identified by HPLC and mass spectrometry. [14C]-trichloromethylthio-labelled captan was completely degraded essentially to [14C]CO2 (77%) accompanied by small amounts of [14C]CS2 (2%). Thiophosgene was not detectable. Approximately 11.5% of the radioactivity was non-extractable and was believed to result from the reaction of the trichloromethylthio moeity with endogenous compounds of the apple, e.g. protein. The results were compared with those obtained in buffer medium mimicking the same process

Safety and efficacy of bentonite as a feed additive for all animal species

The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) received a request from the European Commission to assess the safety and efficacy of bentonite when used as a technological feed additive (substances for reduction of the contamination of feed by mycotoxins) for all animal species. The applicant, EUBA aisbl (European Bentonite Association) representing six companies, submitted to EFSA a technical dossier to support the application. The applicant proposes to use bentonite at the maximum level of 20,000 mg/kg complete feed. The additive apparently interferes with the analysis of aflatoxin B1 in feed. The safety of the additive was already evaluated by the Panel in an opinion delivered in 2012. Bentonites are safe for all animal species, the consumers and the environment when used at a maximum level of 20,000 mg/kg complete feed. The results of a new genotoxicity study reinforced the previous conclusion that smectites are non-genotoxic. Bentonites are not skin irritants but might be mildly irritant to the eye; based on a new study submitted, the additive is not a skin sensitiser. Owing to its silica content, the additive is a hazard by inhalation for the users. The in vitro study showed that the di- and tri-octahedral smectites tested can adsorb aflatoxin B1 at different concentrations and at pH 5; however, no adequate in vivo studies were available. Therefore, the Panel cannot draw conclusions on the additive\u2019s efficacy. The Panel further considers the safety and efficacy conclusions to apply equally to the di- and tri-octahedral smectites under assessment. The FEEDAP Panel posted some recommendations regarding the maximum content of other minerals in the additive and the incompatibilities of the additive with other medicinal substances. The Panel also drew a remark concerning the denomination of the additive and the current regulatory definition of Bentonite

Safety and efficacy of a preparation of algae interspaced bentonite as a feed additive for all animal species

Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) was asked to deliver a scientific opinion on the safety and efficacy of a preparation of algae interspaced bentonite when used as a flatoxin B1 binder for all animal species. The additive is composed of bentonite and algae belonging to Ulva spp. The additive is considered safe for weaned piglets, dairy cows and chickens for fattening at the maximum recommended dose of 125 mg/kg complete feed (a wide margin of safety is established in weaned piglets and dairy cows); this conclusion is extrapolated to all animal species. The additive is not genotoxic. As bentonite is essentially not absorbed from the gut lumen and algae from Ulva spp. are not expected to be of concern for human consumption, the FEEDAP Panel considers that the use of the additive in animal nutrition is safe for consumers. The additive is not an irritant to the skin or the eyes and it is considered to have low inhalation toxicity. However, the additive has a high dusting potential and contains a high proportion offine particles. A high level of inhalation exposure to an inert dust may be hazardous. In the absence of data, the Panel could not conclude on dermal sensitisation. As the components of the additive are of natural origin (soil and marine environment), it is not expected that the use of the additive in animal nutrition would adversely affect the environment. The FEEDAP Panel could not conclude on the efficacy of the additive for all animal species

In the absence of data, the Panel could not conclude on dermal sensitisation. As the components of the additive are of natural origin (soil and marine environment), it is not expected that the use of the additive in animal nutrition would adversely affect the environment.

Safety and efficacy of Monteban® G100 (narasin) for chickens for fattening

The feed additive Monteban\uae G100, containing the active substance narasin, an ionophore anticoccidial, is intended to control coccidiosis in chickens for fattening at a dose of 60\u201370 mg/kg complete feed. Narasin is produced by fermentation. Limited data on the taxonomic identification of the production strain did not allow the proper identification of strain NRRL 8092 as Streptomyces aureofaciens. The FEEDAP Panel cannot conclude on the absence of genetic determinants for antimicrobial resistance in Streptomyces spp. under assessment. Based on the available data set, the FEEDAP Panel cannot conclude on the safety of Monteban\uae G100 for chickens for fattening. The simultaneous use of Monteban\uae G100 and certain antibiotic drugs (e.g. tiamulin) is contraindicated. Narasin is not genotoxic. No indication of carcinogenicity or developmental toxicity was found at the doses tested in the mouse, rat and rabbit. The lowest no observed effect level (NOEL) identified in the oral toxicity studies was 0.5 mg/kg body weight (bw) per day for the neuropathy seen in a one-year dog study. The acceptable daily intake (ADI) derived from this NOEL is 0.005 mg narasin/kg bw applying a uncertainty factor of 100. Monteban\uae G100 is safe for the consumer. Maximum residue limits (MRLs) of 50 lg narasin/kg for all wet tissues ensure consumer safety. Monteban\uae G100 is irritatant to the eyes but not to the skin. It has the potential to induce skin sensitisation. Inhalation exposure would pose a risk to persons handling the additive. Narasin, when used as a feed additive for chickens for fattening at 70 mg/kg feed, is not expected to pose a risk to the environment. The risk for sediment compartment cannot be assessed. The FEEDAP Panel cannot conclude on the efficacy of Monteban\uae at the minimum applied dose of 60 mg narasin/kg complete feed for chickens for fattening
