Levels Of Heavy Metals In Deposited Dust And Soil From Selected Primary Schools In Dar Es Salaam, Joseph Yoeza Naimani Philip, Eliamini Ismail Mkenga, Othman Chande Othman Jul 2018

Levels Of Heavy Metals In Deposited Dust And Soil From Selected Primary Schools In Dar Es Salaam, Joseph Yoeza Naimani Philip, Eliamini Ismail Mkenga, Othman Chande Othman

Tanzania Journal of Science

The objective of this study was to examine the levels of heavy metals, lead, manganese, nickel, copper, chromium and cadmium in standard one and kindergarten classroom dusts and playing ground soils from selected primary schools along Morogoro road highway (Kimara, Mbezi, Kibamba and Kiluvya primary schools) and away from Morogoro road highway (Makabe, Msumi and Mbopo primary schools) as well as in the Dar es Salaam city center (Uhuru, Mzimuni, Dr. Omari Ali Juma, Manzese and Ubungo National House primary schools), Tanzania. The samples were acid digested and the supernatant analyzed using inductively coupled plasma optical emission spectrometer (ICP-OES). The …


Levels Of Heavy Metals In Selected Facial Cosmetics Marketed In Dar Es Salaam, Tanzania, Joseph Yoeza Naimani Philip, Silvia John, Othman Chande Othman Jul 2018

Levels Of Heavy Metals In Selected Facial Cosmetics Marketed In Dar Es Salaam, Tanzania, Joseph Yoeza Naimani Philip, Silvia John, Othman Chande Othman

Tanzania Journal of Science

The aim of this study was to determine the levels of heavy metals: lead, cadmium, copper, zinc, arsenic and mercury in facial cosmetics (lipstick, lip glossy, facial powder, foundation, eyeliner, eye shadow and mascara) which were purchased randomly in Dar es Salaam, Tanzania. The levels of lead, cadmium, copper and zinc were determined using Atomic Absorption Spectrometry (AAS). The levels of arsenic were determined using Hydride Generation Atomic Absorption Spectrometry (HGAAS), and levels of mercury were determined using Cold Vapour Atomic Absorption Spectrometry. Prior to determination of the concentration of heavy metals, the samples were acid digested. The average order …


Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender May 2018

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …


Heavy Metals And Cyanide Distribution In The Villages Surrounding Buzwagi Gold Mine In Tanzania, Edwin Sifuel Gomezulu, Agnes Mwakaje, Jamidu, H.Y. Katima May 2018

Heavy Metals And Cyanide Distribution In The Villages Surrounding Buzwagi Gold Mine In Tanzania, Edwin Sifuel Gomezulu, Agnes Mwakaje, Jamidu, H.Y. Katima

Tanzania Journal of Science

The study aimed at assessing the levels of heavy metals and cyanide in water and sediments in villages surrounding Buzwagi gold mine, both during wet and dry seasons.  A total of 56 samples of water (28 from each season) and 44 samples of sediments (22 from each season) were collected from the wells in the area and were analyzed for total cyanide and heavy metals.  The total cyanide was analyzed spectrophotometrically whilst the heavy metals were analyzed by an Inductively Coupled Plasma (ICP). The Pb and Fe levels in water were found to exceed 10 µg/L and 2000 µg/L respectively, …


Status Of Selected Heavy Metals Dispersion From Top Soil In And Around Automobile Workshop Areas In Zanzibar Municipality, Tanzania, John Am Mahugija, Hawa M Sheikh May 2018

Status Of Selected Heavy Metals Dispersion From Top Soil In And Around Automobile Workshop Areas In Zanzibar Municipality, Tanzania, John Am Mahugija, Hawa M Sheikh

Tanzania Journal of Science

The distributions of selected heavy metals in top soil in areas with and without automobile workshops in Zanzibar municipality were investigated. Sampling was done during dry and rainy seasons. The samples were digested with aqua regia (HCl and HNO3, 3:1) and analysed by Atomic Absorption Spectrophotometry. The concentrations of zinc, copper and lead in the samples ranged 0.27–419.2, 0.10–167 and 0.02–271 mg/kg dry weight, respectively. The concentrations were higher in areas with automobile workshops than those without. The concentrations of the heavy metals were highest at point sources and decreased with increase in distance during the dry season. The concentrations …


Utilization And Accessibility Of Securinega Virosa For Medical Use In Morogoro Municipality, Sasha Friedrich Apr 2017

Utilization And Accessibility Of Securinega Virosa For Medical Use In Morogoro Municipality, Sasha Friedrich

Independent Study Project (ISP) Collection

Approximately 80% of rural communities in Tanzania utilize the services of traditional healers. This is largely because modern medicine is often expensive, inaccessible, or has undesirable side effects. This study investigates use of traditional medicine in Morogoro Urban district where people do have access to hospitals. In particular, this study aims to assess the utilization and accessibility the plant species Securinega virosa for medicinal use by identifying and interviewing the actors involved in the supply chain from harvester to consumer. I conducted semi-structured interviews with eight traditional healers and one herbal medicine shopkeeper. I expected harvesters to express a decline …


Optimization Of Edxrf For The Study Of Heavy Metal Pollution Of Lake Victoria, Nk Mahommed, In Makundi Nov 2002

Optimization Of Edxrf For The Study Of Heavy Metal Pollution Of Lake Victoria, Nk Mahommed, In Makundi

Tanzania Journal of Science

This study reports on the optimisation and calibration of the Energy Dispersive X-ray Fluorescence (EDXRF) spectrometer installed in the Department of Physics, University of Dar es Salaam. The spectrometer was subsequently utilized to determine concentrations of heavy metals in water hyacinth (Eichhornia crassipes (Mart) Solms.) found growing along the shore of Lake Victoria. The optimal conditions and detection limits were determined experimentally by variation of the excitation parameters. The study found that the use of a collimator with two apertures of diameter 4 mm each placed 8 mm apart and made of materials that do not interfere with elements to …


Assessment Of Heavy Metal Pollution In The Lupa Gold Field, Sw Tanzania, S. R. Mnali Dec 2001

Assessment Of Heavy Metal Pollution In The Lupa Gold Field, Sw Tanzania, S. R. Mnali

Tanzania Journal of Science

The concentrations of AS, Cd, Cr, Cu, Hg and Pb were determined in water, stream sediments, soil, and mine tailings from Lupa Gold Field (LGF), SW Tanzania, in order to assess their pollution levels. As, Cd and Cr were determined by automated Graphite Furnace Absorption Spectrophotometry. Cu and Pb were analysed by Air-Acetylene Flame, while Hg was analysed by Cold Vapour Atomic Absorption Spectrophotometry. The mean concentrations obtained were: As: 0.44 ppb (water), 1.2 ppm (sediments), 0.44 ppm (soil) and 5.2 ppm (tailings); Cd: 0.03 ppb (water), 0.03 ppm (sediments), 0.03 ppm (soil) and 0.50 ppm (tailings); Cr: 1.4 ppb …


The Pharmacology Of Rodenticides, S. A. Peoples Mar 1970

The Pharmacology Of Rodenticides, S. A. Peoples

Vertebrate Pest Conference Proceedings: 4th (1970)

The compounds used as rodenticides are tremendously varied in their chemical structure and mechanism of action. With a few exceptions, these agents are generally poisonous to all animals, including man, and a great deal of study has been directed to their toxicity in animals other than rodents. However, the development of new compounds as Norbormide and certain antifertility drugs which are highly selective in their action may justify the hope that the ideal rodenticide free of secondary toxic hazards will soon be available. Until this happy announcement is made, a review of the pharmacology of the older compounds is in …
