Residues Of Thiamethoxam And Mefenoxam In Vegetative And Floral Tissue Of Soybean At The Early Reproductive Stage Resulting From Seed Treatments, Carolina Camargo, Daniel D. Snow, Sathaporn Onanong, Thomas Hunt, Blair Siegfried
Residues Of Thiamethoxam And Mefenoxam In Vegetative And Floral Tissue Of Soybean At The Early Reproductive Stage Resulting From Seed Treatments, Carolina Camargo, Daniel D. Snow, Sathaporn Onanong, Thomas Hunt, Blair Siegfried
Department of Entomology: Faculty Publications
Thiamethoxam with mefenoxam is the most widely used neonicotinoid insecticide/fungicide mixture applied to soybean (Glycine max [L]) as seed treatments. Based on the systemic nature of thiamethoxam and mefenoxam, residues of this insecticide/fungicide mixture may be present in soybean vegetative and floral tissue and negatively impact beneficial insects. Although neonicotinoids are often applied in combination with systemic fungicides, the research on ecological risks of neonicotinoids has been focused on the analysis of these compounds without considering their interaction with other agrochemicals. The objective of this study was to identify the concentration of thiamethoxam and mefenoxam in soybean flowers and …
Ground Ingredients: Analysis Of Lead Exposure In The California Condor’S (Gymnogyps Californianus) Ground Foraging Habitat, Evan Michael Mcwreath
Ground Ingredients: Analysis Of Lead Exposure In The California Condor’S (Gymnogyps Californianus) Ground Foraging Habitat, Evan Michael Mcwreath
Graduate Theses, Dissertations, and Problem Reports (ETD)
The California Condor (Gymnogyps californianus) is a critically endangered species that reached its nadir in 1987 with a population of 27 birds in the wild. Intensive management efforts have been implemented to aid the condors’ recovery, however, anthropogenic factors, like use of lead ammunition, continue to cause fatalities in this vulnerable population. Lead toxicosis, which is responsible for approximately 40% of all condor deaths since 1992, is one of the most significant threats to condors. In birds lead poisoning leads to neurological dysfunction, reproductive impairment, immune suppression, gastrointestinal disturbance, anemia, and ultimately increased vulnerability to predation, starvation, and infection. For …

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

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 …
One-Compound-Two-Pharmacophores: Design, Synthesis And Antimalarial Activities Of Chloroquinoline-Cassiarin, Thobias M. Kalenga, Monica M. Ndoile, Quintino A. Mgani
One-Compound-Two-Pharmacophores: Design, Synthesis And Antimalarial Activities Of Chloroquinoline-Cassiarin, Thobias M. Kalenga, Monica M. Ndoile, Quintino A. Mgani
Tanzania Journal of Science
This paper describes the design and synthesis of a potential antimalarial compound, chloroquinoline-cassiarin (6) using 4,7-dichloroquinoline and the natural product barakol (1) extracted from the leaves of Cassia siamea as starting materials. In this paper a one compound-two-pharmacophores concept is introduced in which coupling of two known pharmacophores into one has been described. The concept is not only useful to organic synthesis but also to drug development researches. The synthesized compound 6 exhibited potent in vitro antimalarial activity at IC50 = 0.51 µM, and low toxicity where at 20 µM, 80% viability of HeLa cells was observed.
Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
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 …
Levels Of Heavy Metals In Drinking Water, Cosmetics And Fruit Juices From Selected Areas In Dar Es Salaam, Tanzania, John Am Mahugija
Levels Of Heavy Metals In Drinking Water, Cosmetics And Fruit Juices From Selected Areas In Dar Es Salaam, Tanzania, John Am Mahugija
Tanzania Journal of Science
Heavy metals were determined in samples of drinking water, cosmetics (nail polish, lip glosses and hair dye) and fresh fruit juices in Dar es Salaam. The samples were analyzed using Atomic Absorption Spectrometry (AAS) after digestion with concentrated acids, filtration and dilution. Lead, zinc and iron were detected in the water samples and the concentration ranges were below detection limit (BDL) to 0.114, 0.01 to 1.47 and 0.027 to 0.39 mg/L, respectively, whereas cadmium was not detected. The concentrations of lead in 70.83% of the samples exceeded the WHO permissible limit, implying that the water in most of the areas …
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
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 …
