The Impact of the Food Quality Protection Act on the Future of Plant Disease Management.

The Food Quality Protection Act mandates new considerations in pesticide regulatory decisions. Endocrine disruption, determination of the need for an additional safety factor for infants and children, aggregate exposure to each pesticide, and cumulative exposure to pesticides with a common mechanism of toxicity will all become part of the risk assessment process. A reduction in availability of fungicides for many current uses appears to be a likely result of this act.

Reductive assays for S-nitrosothiols: implications for measurements in biological systems.

Bioactive SNOs are found in many tissues. We speculated SNOs might be misidentified in conventional assays which reduce NO-3 to NO. S-Nitrosothiols were exposed to saturated VCl3 in HCl, 1% KI in acetic acid, photolysis, or CuCl and CSH in He; NO was measured by chemiluminescence.
