Assessment of Mercury and Arsenic Levels in Lemongrass at Kihonda and Mafisa in Morogoro, Tanzania | Chapter 3 | Atomic Absorption Spectroscopy and Physical Experiences in Morogoro, Tanzania

 

As urbanisation and industrialisation continue to expand, there is a growing concern about the potential contamination of crops with heavy metals from various sources, including industries, infrastructures, pollution and agricultural practices. For instance, the quality and safety of lemongrass can be compromised by environmental factors, including the presence of heavy metals such as mercury and arsenic. The study aims to assess the presence and concentration of heavy metals in lemon grasses. These could have implications for the safety and quality of the lemon for various uses, including culinary and medicinal purposes. The research employs analytical techniques such as atomic absorption spectroscopy (AAS) to determine the levels of mercury and arsenic in the lemon grass samples. The findings of the study provide valuable insights into the environmental conditions and potential health risks associated with the consumption of lemon from Kihonda and Mafisa in Morogoro. High levels of heavy metals in food can cause serious health risks to consumers. The analysis of the concentration of arsenic and mercury in Lemongrass from Kihonda and Mafisa is compared. The concentration of arsenic in Lemongrass from Kihonda is slightly lower than that from Mafisa by 0.00186mg/kg. On the other hand, the concentration of mercury in Lemongrass from Kihonda is higher than that from Mafisa by 0.00493 mg/kg. According to studies, resulting from chronic exposure to heavy metals through contaminated food can lead to various health issues, including neurological disorders, gastrointestinal and kidney problems. It is necessary to know the level of heavy metals for safety. The study enables the readers to know the quality of the lemongrass for various uses, including culinary and medicinal purposes. The findings underscore the importance of continuous monitoring and management of soil and crop practices to ensure food safety to be in compliance with health guidelines. Immediate actions should include enhanced soil management and the adoption of improved agricultural practices.
