Respirable dust and respirable silica exposure in Ontario gold mines. A comprehensive survey of respirable dust and respirable silica in Ontario gold mines was conducted by the Ontario Ministry of Labor during The aim was to assess the feasibility of introducing gravimetric sampling to replace the assessment method which used konimeters, a device which gave results in terms of number of particles per cubic centimeter ppcc of air. The study involved both laboratory and field assessments. The field assessment involved measurement of airborne respirable dust and respirable silica at all eight operating gold mines of the time.

My days always go better when I take a morning walk. I can always tell which house has gotten an early start on the laundry by the scents wafting to me as I pass. And out in the country where I am, with houses a minimum of two acres apart, that waft is coming quite aways. Fabric softener, and its cousin dryer sheets, have been around for so long and are such a part of many laundry routines that my trying to convince you to stop using them might sound flat out weird. Fabric softener and dryer sheets are all one topic because dryer sheets are merely squares coated in dry fabric softener. Their purpose and function are nearly identical. They only differ in their method of delivery. Fabric softener is lubricant for fabrics. What happened to the snuggly bears and bursting flowers? This lubricant on fabrics also reduces static electricity. Its positive charge absorbs the excess electrons of negatively charged fabrics. The coating can also reduce wrinkles. Silicone softeners do this by encasing fabric fibers in an elastic network. This network aids the fabric in recovering from a crease or other deformation. The final feature of fabric softener is often the one people prize the most: their fragrance. Fragrance is a huge selling point for all laundry products. Laundry manufacturers used to rely only on promises of getting laundry clean, but then they learned that consumers were much more swayed by how the laundry smelled. Since the fabric softeners always come after the cleansing cycle, they are able to deposit a plentiful load of scent on the fabrics. These lubricant residues build up on fabric in wash after wash, creating a layer of dinginess over time.
