Inhalation Toxicity of Vinyl Chloride and Vinylidene Chloride [PDF]
Environmental Health Perspectives, 1977 Exposure of mice to 1000 ppm of vinyl chloride (VC), 6 hr/day, 5 days/week, caused some acute deaths with toxic hepatitis and marked tubular necrosis of the renal cortex. Starting the sixth month, mice exposed to 1000, 250, or 50 ppm of VC became lethargic, lost weight quickly, and died.

Reducing concrete permeability by using natural pozzolans and reduced aggregate-to-pasteratio
Journal of Civil Engineering and Management, 2015 Improved durability of concrete is mainly achieved with low-permeability. Permeability depends on permeability of the bulk cement paste (CP) and that of its interfacial transition zone (ITZ).
