Ergonomics contribution to chemical risks prevention: An ergotoxicological investigation of the effectiveness of coverall against plant pest risk in viticulture.

The purpose of this article is to present the contribution of a trans-disciplinary approach focused on ergonomics and chemical risk control. We shall more precisely discuss how such an approach carried out in the field of agricultural work has made it possible to highlight serious shortcomings in the effectiveness of the coveralls that are supposed to protect vineyard workers from pesticides. The study results, as well as the whistle-blow that followed have questioned the control and prevention measures used until then.

Rational Design of Low Molecular Mass Organogelators: Toward a Library of Functional N-Acyl-1,ω-Amino Acid Derivatives.

N-Acyl amino acids RCONH(CH ) COOR represent a new family of organogelators that can be obtained in a combinatorial approach from libraries of activated acids and amino acids. The amounts required for gel formation in solvents such as DMF are less than 1 mg mL and the gels formed are very stable. n=5, 7, 10, 12; R=aromatic or aliphatic group; R =H or alkali metal (Na).
