Inhalation toxicity of suspended particulate pesticide-supracide FD.

Effect of copper binding by suspended particulate matter on toxicity.

The kinetics of Cu(II) interactions with Susquehanna River (mid-Atlantic, USA) particle suspensions using the copper ion selective electrode (Cu-ISE) method indicated that the concentration of Cu2+ in both the suspension and filtrate was kinetically controlled; the reaction of Cu(II) in the suspension was faster than that in the filtrate. Bioassay tests were performed in continuous flow-through...

Design of an Inhalation Chamber to Expose Laboratory Animals with Suspended Particulate Matter by Numerical Simulation Method

Introduction: Usually, in the toxicological studies of airborne particulate pollutants, inhalation exposure chambers are used for providing and distributing the test atmosphere uniformly and stability in the respiratory zone of laboratory animals. The purpose of this study was to design, evaluate and optimize a whole-body exposure chamber, specifically for small laboratory animals exposed to pa...

Zinc toxicology following particulate inhalation

The current mini-review describes the toxic effects of zinc inhalation principally in the workplace and associated complications with breathing and respiration. The International ClassiÞ cation of Functioning, Disability and Health Criteria were used to speciÞ cally select articles. Most of the commercial production of zinc involves the galvanizing of iron and the manufacture of brass. The reco...

Methanol inhalation toxicity.

Significant toxicity can result from intentional methanol inhalation. We report seven cases, involving four patients, of intentional inhalation of CARB-MEDIC carburetor cleaner containing toluene (43.8%), methanol (23.2%), methylene chloride (20.5%), and propane (12.5%). Patients arrived at the emergency department with central nervous system depression, nausea, vomiting, shortness of breath, p...
