Sweepers
A street sweeper or street cleaner may refer to a person's occupation or to a machine that cleans streets. Street sweepers have been employed in cities as "sanitation workers" since sanitation and waste removal became a priority. A street-sweeping person would use a broom and shovel to clean off litter, animal waste and filth that accumulated on streets. Later, water hoses were used to wash the streets. Machines were created in the 19th century to do the job more efficiently. Today, modern street sweepers are mounted on truck bodies and can vacuum debris that accumulates in streets. Modern sweepers Street sweepers are capable of collecting small particles of debris. Many street sweepers produced today are PM10 and PM2.5 certified, meaning that they are capable of collecting and holding particulate matter sized less than 10μm and even down to 2.5μm. Despite advancements in street sweeping technology, the mechanical broom type street sweeper accounts for approxima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sanitation Workers
A sanitation worker (or sanitary worker) is a person responsible for cleaning, maintaining, operating, or emptying the equipment or technology at any step of the sanitation chain.World Bank, ILO, WaterAid, and WHO (2019)Health, Safety and Dignity of Sanitation Workers: An Initial Assessment World Bank, Washington, DC.

More broadly speaking, sanitation workers may also be involved in cleaning streets, parks, public spaces, sewers, stormwater drains, and public toilets. Another definition is: "The moment an individual’s waste is outsourced to another, it becomes sanitation work." Some organizations use the term specifically for municipal solid waste collectors, whereas others exclude the workers involved in management of solid waste (rubbish, trash) sector from its definition. Sanitation workers are essential in maintaining safe sanitation services in homes, schools, hospitals, and other settings and prote ...

Road Debris
Road debris, a form of road hazard, is debris on or off a road. Road debris includes substances, materials, and objects that are foreign to the normal roadway environment. Debris may be produced by vehicular or non-vehicular sources, but in all cases it is considered litter, a form of solid waste., AAA Foundation for Traffic Safety press release o"The Safety Impact of Vehicle-Related Road Debris" Gerry Forbes and John Robinson, June 2004 Debris may tend to collect in areas where vehicles do not drive, such as on the edges (shoulder), around traffic islands, and junctions. Road spray or tire kickup is road debris (usually liquid water) that has been kicked up, pushed out, or sprayed out from a tire. In 2004, a AAA Foundation for Traffic Safety study revealed that vehicle-related road debris caused 25,000 accidents and nearly 100 deaths a year. Causes Road debris can be caused by various factors, including objects falling off vehicles or natural disasters and weather, specifical ...

Joseph Whitworth
Sir Joseph Whitworth, 1st Baronet (21 December 1803 – 22 January 1887) was an English engineer, entrepreneur, inventor and philanthropist. In 1841, he devised the British Standard Whitworth system, which created an accepted standard for screw threads. Whitworth also created the Whitworth rifle, often called the "sharpshooter" because of its accuracy, which is considered one of the earliest examples of a sniper rifle. Whitworth was created a baronet by Queen Victoria in 1869. Upon his death in 1887, Whitworth bequeathed much of his fortune for the people of Manchester, with the Whitworth Art Gallery and Christie Hospital partly funded by Whitworth's money.

Elgin, Illinois
Elgin ( ) is a city in Cook and Kane counties in the northern part of the U.S. state of Illinois. Elgin is located northwest of Chicago, along the Fox River. As of the 2020 Census, the city had a population of 114,797, the seventh-largest city in Illinois. History The Indian Removal Act of 1830 and the Black Hawk Indian War of 1832 led to the expulsion of the Native Americans who had settlements and burial mounds in the area and set the stage for the founding of Elgin. Thousands of militiamen and soldiers of Gen. Winfield Scott's army marched through the Fox River valley during the war, and accounts of the area's fertile soils and flowing springs soon filtered east. In New York, James T. Gifford and his brother Hezekiah Gifford heard tales of this area ripe for settlement, and they traveled west. Looking for a site on the stagecoach route from Chicago to Galena, Illinois, they eventually settled on a spot where the Fox River could be bridged. In April 1835, they e ...

Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extend of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options. Categories The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for potability, industrial/domestic use, or restoration (of an environment/ecosystem, generally for health of human/aquatic life). Human consumption Contaminants that may be in untreated water include microorganisms such as viruses, protozoa and bacteria; inorganic ...

Stormwater
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 carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manure
Manure is organic matter that is used as organic fertilizer in agriculture. Most manure consists of animal feces; other sources include compost and green manure. Manures contribute to the fertility of soil by adding organic matter and nutrients, such as nitrogen, that are utilised by bacteria, fungi and other organisms in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life that comprises the soil food web. History According to a Byzantine tradition attributed to Cassianus Bassus pig dung was generally not usable as fertilizer, except for almond trees. Similar views recorded by Columella were unrelated to the Islamic taboos of later centuries, though the medieval Andalusian writer Ibn Bassal and some later writers from Yemen also recorded negative effects of pig dung "burning" plants. Ibn Bassal described a sort of mixed manure with straw or sweeping mixed in as ', implying that was not composed of only manure. The sweepings from hot baths inc ...
