Prior to this, alterations in the peripheral blood andmore » metabolite levels in response to experimental MEMC poisoning have been demonstrated in this species.« lessĮffect of cell size on the reaction of uranium acetate, mercuric chloride, and cyanogen iodide with a strain of Pseudomonas aeruginosa This report describes pathogenesis of branchial and renal lesions in the common freshwater fish, Puntius conchonius exposed chronically to sublethal levels of MEMC. Of these, the methoxy ethyl mercuric chloride (MEMC) is used in agriculture as an antifungal seed dressing, and its toxicity is primarily manifest in the Hg/sup 2 +/ ion. Among the various organomercurials are phenyl mercuric acetate, methyl mercuric dicyanidiamide, methoxy ethyl mercuric chloride, methoxy ethyl mercuric silicate etc. Pathological manifestations causally related to pesticide poisoning have been described in both surficial and internal tissues of the fishes. The controlled abatement consisted of containment of the work area with negative air technology worker protection, including mercury-specific training, use of personal protective equipment, and biological and exposure monitoring and environmental protection, including proper disposal of mercury-bearing hazardous waste material.īranchial and renal pathology in the fish exposed chronically to methoxy ethyl mercuric chlorideĭOE Office of Scientific and Technical Information (OSTI.GOV) Controlled abatement was conducted in one school where remodeling would impact the mercury-bearing flexible gym floors ( approximately 9,000 ft(2) total). These evaluations were conducted in response to concerns by school officials that the floors could contain mercury and could release the mercury vapor into the air, presenting a potential health hazard for students, staff, and visitors. Sampling mercury in bulk flooring material and mercury vapor in air was conducted in nine Idaho schools in the spring of 2006. Mercury vapor is released into air above the surface of these floors. In the 1950s-1970s, PMA was used as a catalyst in the 3M Tartan brand polyurethane flexible floors that were installed commonly in school gymnasiums. Phenyl mercuric acetate (PMA) historically has been used as a catalyst in polyurethane systems.
