Mercury is still used in some diuretics, although substitutes such as thiazides now exist for most therapeutic uses. [79] In 2003, mercury compounds were found in some over-the-counter drugs, including topical antiseptics, stimulant laxatives, diaper-rash ointment, eye drops, and nasal sprays.
The mercury applied to lakes was found in young-of-the-year yellow perch within two months, whereas the mercury applied to wetlands and uplands had a slower but longer influx. [ 22 ] [ 23 ] Acute methylmercury poisoning can occur either directly from the release of methylmercury into the environment or indirectly from the release of inorganic ...
Elemental mercury in the atmosphere can undergo transformation into inorganic mercury forms, providing a significant pathway for deposition of emitted elemental mercury. Some micro-organisms can produce organic mercury, particularly methylmercury, from other mercury forms. Methylmercury can accumulate in living organisms and reach high levels ...
Mercury's orbit is inclined by 7 degrees to the plane of Earth's orbit (the ecliptic), the largest of all eight known solar planets. [112] As a result, transits of Mercury across the face of the Sun can only occur when the planet is crossing the plane of the ecliptic at the time it lies between Earth and the Sun, which is in May or November ...
Mercury poisoning is a type of metal poisoning due to exposure to mercury. [3] Symptoms depend upon the type, dose, method, and duration of exposure. [3] [4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. [1]
Mercury's Caloris Basin is one of the largest impact features in the Solar System. At least 15 ancient basins have been identified on Mercury. [7] Tolstoj is a true multi-ring basin, displaying at least two, and possibly as many as four, concentric rings.
mercury is the third most frequently found toxic substance in waste facilities in the United States (ATSDR, 2001). Mercury is now widespread in the environment (EPA, 1997; ATSDR, 2001). The long-range atmospheric trans-port of mercury (Ebinghaus et al., 2001), and its conversion to organic forms through bio-accumulation in the aquatic
Three-seeded mercury can be found growing in moist to mesic black soil prairie, openings or lightly shaded areas of upland and floodplain forest, thickets, seeps, riverbanks and lake shores, limestone glades and bluffs, fields, fence rows, roadside and railroad right-of-ways, vacant lots, and waste areas.
