16.3 (11.7-22.7) IU /mL for FHA and 15.4 (10.1-23.6) IU /mL for Prn. Antibody concentrations were below the protective level of 0.1 IU /mL in 26.4% of the sera for DT and in 8.6% of the sera for TT. ...

Evaluation of the migration of chemicals from baby bottles under standardised and duration testing conditions.

below their respective specific migration limits (SML s). The reference experiment confirmed the migration of some of the compounds previously detected in the EU repetitive-use experiment, though at lower ...

Serodiagnosis of whooping cough in Belgium: results of the National Reference Centre for Bordetella pertussis anno 2013.

2 weeks with anti- PT levels below the threshold for acute infection, a second sample collected 2-3 weeks later is needed a definitive diagnosis. For 503 (23.0%) early samples, a second serum sample was ...

Quantitative Determination of Migrating compounds from Plastic Baby Bottles by Validated GC-QqQ-MS and LC-QqQ-MS Methods

kg−1 and 2,2,4-trimethyl-1,3-pentanediol diisobutyrate (TXIB) at 348 μg kg−1. However, most of the targeted compounds were not detected or below the LOQ. Service:  Contaminants organiques et additifs ...

Co-exposure of ELF-magnetic fields and chemical mutagens: An investigation of genotoxicity with the SOS-based VITOTOX test in Salmonella typhimurium.

Response, Genetics Abstract: It is believed that extreme low frequency magnetic fields (ELF- MF) are not mutagenic, at least at exposure levels below 100 μT. Synergistic or co-operative effects with ...

Contamination of freshly slaughtered pig carcasses with enteropathogenic Yersinia spp.: Distribution, quantification and identification of risk factors.

the majority of the carcass samples (97.0%) had Yersinia concentrations below the detection limit of enumeration (<1.30 log10 CFU/100 cm(2)). The initial presence of Y. enterocolitica in the tonsils ...

Agronomic Practices for Improving Gentle Remediation of Trace Element-Contaminated Soils.

field trials demonstrating successful GRO remains well below the number of studies carried out at a greenhouse level. The move from greenhouse to field conditions requires incorporating agronomical ...
