Salt vs Irbid

Informations

Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.

Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products. Of the annual global production of around two hundred million tonnes of salt, about 6% is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use. Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods. Sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute. Excessive salt consumption may increase the risk of cardiovascular diseases, such as hypertension, in children and adults. Such health effects of salt have long been studied. Accordingly, numerous world health associations and experts in developed countries recommend reducing consumption of popular salty foods. The World Health Organization recommends that adults should consume less than 2,000 mg of sodium, equivalent to 5 grams of salt per day.

Irbid (Arabic: إرْبِد‎), known in ancient times as Arabella or Arbela (Άρβηλα in Ancient Greek), is the capital and largest city of the Irbid Governorate. It also has the second largest metropolitan population in Jordan after Amman, with a population of around 1,911,600. Irbid is located about 70 kilometres (43 mi) north of Amman on the northern ridge of the Gilead, equidistant from Pella, Beit Ras (Capitolias), and Um Qais, and approximately 20 kilometres (12 mi) south of the Syrian border. Irbid was built on successive Early Bronze Age settlements and was possibly the biblical Beth Arbel and the Arbila of the Decapolis, a Hellenistic league of the 1st century BCE through the 2nd century CE.

The population of Irbid swelled in the late 19th century, and prior to 1948 it served as a significant centre of transit trade.Irbid is the second largest metropolitan in Jordan by population after Amman. But as a city Irbid is the third largest one after Amman and Az Zarqa. The province of Irbid Governorate has the second largest population, and the highest population density in the kingdom. The city is a major ground transportation hub between Amman, Syria to the north, and Mafraq to the east. The Irbid region is also home to several colleges and universities. The two most prominent universities are Jordan University of Science and Technology and Yarmouk University.
