  • Essay / Detection of heavy metals in drinking water of Pishin district (Balochistan, Pakistan) using atomic absorption spectrometry

    Table of contentsAbstractWater and heavy metalsMaterials and methodsLamp currentResults and conclusionsReferencesAbstractThis study was designed to find out the heavy metal content of water samples collected from tube wells and from different areas of Pishin district. Analysis of different water samples is carried out to check parameters such as electrical conductivity, pH, load of population using fertilizers in the chosen area. According to this analysis process, it is determined that the age of tube wells never affects the amount of heavy metals. Heavy metals such as antimony and aluminum are present in levels higher than standardized values. The presence of arsenic in drinking water is due to anthropogenic activities taking place near tube wells (chemical industries). Introduction:· Area Description: Pishin district is a region of Balochistan province, due to climatic conditions, the temperature in winter reaches subzero temperatures. point and in summer the temperature reaches 40 degrees calicos. This area is located 5,104 feet above sea level. Pishin is famous for its agricultural products. In this area, the irrigation process is done using water from artificial canals (boreholes). The most common groundwater source in Pishin district is tube well and Karez system. · Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”?

Pure water provides us with essential minerals, but when water is contaminated, it causes diseases such as cancer, reproductive disorders, cardiovascular and neurological disorders. Heavy metal contamination mainly affects infants and young people due to their developmental stage. Due to higher sensitivity in children, heavy metals cause various disorders in children such as uncontrolled temper, subconsciousness and hyperactivity. They consume more metals from food products due to greater contamination of food with heavy metals. Heavy metals such as arsenic and its compounds released from different chemical industries are toxic to human health (Choudhury et al., 2009). Exposure to antimony causes cardiovascular problems. According to the EPA, lead is a carcinogen to human health. Exposure to lead causes respiratory problems. Tap water is more contaminated due to lead (ASTDR, 2000). Aluminum (Al) is the third most abundant element in the Earth's crust. The accumulation of aluminum in the body's cells leads to neurological disorders (Richard, 1993). According to the EPA, excessive amount of essential metals in water leads to different disorders while Cu, Zn, Cr are essentially necessary for the human body (Goyer and Clarkson, 2001).·Materials and methodsThe aim of this study is to evaluate a group of metals such as (Pb, Sb, Al, As) to know the pH and conductivity of water samples and also to assess the impacts of heavy metals on human health. · Sample collection: Fifty (50) water samples collected from twelve villages in Pishin district. The sample was collected in polyethylene bottles and labeled. Each sample is matched with 4 m of nitric acid (Michael, 1982; APHA, et al., 1992). · Analysis of samples: pH meter used to determine., 1993.
