A stye is an infection of an oil gland in the eyelid. It produces a red, swollen, painful lump on the edge or inside surface of the eyelid. Styes usually occur closer to the surface of the eyelid than do chalazia.
The most abundant salts in the ocean are chlorine, sodium, magnesium, sulfur, calcium, and potassium. Ocean salinity is affected by multiple factors including ice melt, inflow of river water, evaporation, precipitation, wind, wave motion, and ocean currents.
Water that is saline contains significant amounts (referred to as concentrations) of dissolved salts, the most common being the salt we all know so wellâsodium chloride (NaCl). In this case, the concentration is the amount (by weight) of salt in water, as expressed in parts per million (ppm).ater that is saline contains significant amounts (referred to as concentrations) of dissolved salts, the most common being the salt we all know so wellâsodium chloride (NaCl).
