Growers said that DuPont's assurances that a contaminant caused their problems led them to use fresh Benlate supplies when they replanted, causing new damage and business setbacks.
Chinese officials have disputed the F.D.A. contention that the contaminant caused death and injury, and they have insisted on the right to inspect American drug plants if the F.D.A. insists on inspecting Chinese ones.
Arsenic is a well-known environmental contaminant, causing toxicity in different organs.
The presence of the contaminant caused a decrease in the microbial biomass and in phosphomonoesterase, β-glucosidase and particularly, urease activities.
The difference between the last two experiments is that the first looked at the long-term effects and the latter at short-term effects, suggesting that exposure time to the contaminant caused BF to react differently.
Also, the mechanism in which the OSCS contaminant caused the anaphylactoid responses was characterized [32], and recently how these semi-synthetic GAGs activate the complement system and how they affect GAG-dependent cell signaling pathways have also been investigated [33].
Acrylamide is not the only processing contaminant causing concern.
Formaldehyde is a well-known airborne contaminant causing eye, nose, and throat irritation as well as airway irritation and slight neuropsychologic changes (Hester and Harrison 1998; Samet et al. 1988).
Chemical stress from moisture or contaminants causes corrosion to interconnects, and as a result interconnect failures occur in which the interconnects cannot conduct the intended functions.
They are scientists at the Energy Department's Lawrence Berkeley National Laboratory, and the morning's experiment concerned another kitchen conundrum, a fight against physics: how to remove harmful contaminants caused by cooking.
