Yangebup Lake
Yangebup Lake is a freshwater lake in the suburb of Yangebup, south-west of the central business district of Perth, the capital of Western Australia. It is part of Beeliar Regional Park. Overview Yangebup Lake's name is derived from the Nyungar word for the locally-growing bullrush (''Typha domingensis''), ''yanget''. The lake and its name were first recorded by European settlers in 1841 while the suburb of Yangebup officially received its name in 1977. The same naming origins incidentally apply for Lake Yanchep and its eponymous suburb, Yanchep, located in the north of Perth. The area surrounding the lake historically served as camping, gathering and hunting grounds for the local Wadjuk people of the Noongar nation, who are estimated to have lived in the area for 40,000 years. The wetlands of Beeliar Regional Park were highly important to the local indigenous population as a source of both food and water. North Lake Road, which passes the lake to the north-east, follows what f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yangebup, Western Australia
Yangebup is a southern suburb of Perth, Western Australia in the City of Cockburn. It takes its name from the nearby Yangebup Lake. History The name Yangebup was first recorded in 1841 and may be derived from the Aboriginal word, ''Yanget'', for the species of native flax or bullrush found around the lake. It was approved as the name for the suburb in 1977. Geography The suburb is located from the Perth central business district. It is bounded by the freight rail line and North Lake Road to the north, Hammond Road to the east, Beeliar Drive to the south and Stock Road to the west.

Peel Estate
The Peel Estate was an area of land in the south of Perth, Western Australia, predominantly in what is now the City of Kwinana, City of Rockingham and the Shire of Serpentine–Jarrahdale. The estate twice featured prominently in Western Australian history. In the early days of colonial Western Australia, then the Swan River Colony, the large land grant awarded to Thomas Peel became known as the Peel Estate. In the 1830s, Peel attempted to populate the estate with European settlers and turn it into a successful agricultural region but the venture failed. The Peel Estate featured a second time in the states history 80 years later when it was part of the assisted migration Group Settlement Scheme, which operated in Western Australia from the early 1920s. Like its predecessor, this venture was also a failure, with most settlers abandoning the estate because of the low quality of the land which was, for the most part, unsuitable for the intent of the scheme, dairy farming. The failur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae Blooms
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. ''Algal bloom'' commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels to more harmful effects like blocking sunlight from reaching other or ...

Eutrophic
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus. In coastal waters on the other hand, the main contributing nutrient is more likely to be nitrogen, or nitrogen and phosphorus together. This depends on the location and other factors. When occurring naturally, eutrophication is a very slow process in which nutrients, especially phosphorus compounds and organic matter, accumulate in water bodies. These nutrients derive f ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrogen
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids ( DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere. Many indus ...

Woodman Point
Woodman Point is a headland on the west coast of Western Australia. It is located in the Perth suburb of Coogee, south-south-west of the city centre and south of Fremantle. It extends westward into the Indian Ocean. The coastal waters immediately to the north of the point are known as Owen Anchorage, while to the south is Jervoise Bay. Woodman Point marks the northern extent of Cockburn Sound. Woodman Point is contained completely within the Woodman Point Regional Park, a regional park with recreational facilities including parklands, playgrounds, jetties, and a caravan park; and historic sites including a World War II prisoner-of-war camp and World War II munitions bunkers. History Woodman Point was named after Thomas Woodman, who accompanied Captain James Stirling on the 1827 expedition that explored the upper reaches of the Swan River. When Stirling returned in 1829 with the first settlers for the Swan River Colony, Woodman Point would have been one of the first ...

Storm Water
Stormwater, also spelled storm water, is water that originates from precipitation (storm), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil ( infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff. Most runoff is conveyed directly as surface water to nearby streams, rivers or other large water bodies (wetlands, lakes and oceans) without treatment. In natural landscapes, such as forests, soil absorbs much of the stormwater. Plants also reduce stormwater by improving infiltration, intercepting precipitation as it falls, and by taking up water through their roots. In developed environments, such as cities, unmanaged stormwater can create two major issues: one related to the volume and timing of runoff (flooding) and the other related to potential contaminants the water is carrying (water pollution). In addition to the pollutants carried ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Rockingham, Western Australia
East Rockingham is an industrial suburb within the Kwinana Industrial Area, part of Perth, and located within the City of Rockingham. History The suburb developed as a rural community in the 1850s when various pioneers took up land and settled in the area along Mandurah Road; however, the community declined following the opening of the port at Rockingham in 1872. The Rockingham Road Board's offices were located in East Rockingham between 1905 and 1929. The Stephenson- Hepburn Plan for Perth and Fremantle (1955) identified the strategic importance of the locality for industrial development. The suburb today contains various industrial developments, with LandCorp making plans to release more land for industrial purposes. The Water Corporation intends to construct a wastewater treatment facility in East Rockingham. The suburb was named Challenger for a period between 1992 and 1996. It is home to two caravan parks.

Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromium
Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, and brittle transition metal. Chromium metal is valued for its high corrosion resistance and hardness. A major development in steel production was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Stainless steel and chrome plating (electroplating with chromium) together comprise 85% of the commercial use. Chromium is also greatly valued as a metal that is able to be highly polished while resisting tarnishing. Polished chromium reflects almost 70% of the visible spectrum, and almost 90% of infrared light. The name of the element is derived from the Greek word χρῶμα, ''chrōma'', meaning color, because many chromium compounds are intensely colored. Industrial production of chromium proceeds from chromite ore (mostly FeCr2O4) to produce ferro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
