Comparative Analysis of Selected Heavy Metals and Trace Elements Content in Hair Dyes Products at Sudanese Market and Their Health Implications

/in /by

Heavy metals are naturally occurring elements that have a high atomic weight.  They have been included in many industrial, domestic, medical and agricultural applications. This raised concerns over their health implications and the environment. The present study was conducted in Khartoum state for females utilizing commercial hair dye, aimed to study health implications of selected heavy metals and trace elements in commercially available hair dyes. The main aim of the present research work refers to the high degree of toxicity of some heavy metals, such as cadmium, mercury, lead and others, that are of public health significance. These health implications depend on various factors such as, type of chemical materials, route of exposure, age, gender, nutritional status, etc. In this context, the researcher compared the findings related to the present studied trace elements and heavy metals with other studies in the literature. 313 participants participating in this study, ages between less than 20 years and more than 40 years. Most of them of university education level. Many of participants have gray hair. The results of this study showed the presence of lead, copper, chromium, nickel and cadmium in all of the analyzed hair dye samples. The pure mineral dyes have higher concentrations of the heavy metals than the synthetic dyes studied. Long term and frequent use of these products polluted with such heavy metals should be avoided. They may cause slow release of metals into the human body and may pose serious health risksto their users. Regulatory agencies saddled with maintaining standard of products should regularly monitor these products for long-term health benefits of the users. Heavy metals of Cd, Pb, Cu,, Hg Cr and Ni, were found in all hair dye samples tested. Heavy metals in blood samples of participants cause many symptoms and disease after using hair dyes.  The most concentrated   heavy metals and trace elements (i.e. Pb, Cd, Mn, Hg, Cu and Ni) in blood samples of participants were tested. Results clarified that the high concentration represented for LEAD in blood samples by FLAME AAS and GF AAS. The results also showed the socio demographic factors for using hair dyes, and factors behind using synthetic hair dyes instead of natural hair dyes. Many studies and researches that focused on the topic of the current study confirmed the presence of heavy metals in the cosmetics of poetry of hair dyes and different types of henna. Some women differ in the presence of heavy metals in their vital components, such as hair and blood, depending on their use of cosmetics and the number of times used.

Evaluation and Analysis of the Effects of Feed Supplements, Including both Organic and Inorganic Selenium, on the Production of Layer Eggs

This research aims to evaluate and analyze the provision of additional feed in the form of selenium (Se) on the performance of egg production produced by layers. This research took the main object in the form of 60 weeks old laying hens with the Isa Brown strain. The research was carried out using a Completely Randomized Design (CRD) method with Duncan’s advanced test. The results of this study explain that providing additional feed in the form of selenium (Se) in several doses has a very real influence on egg production performance (egg weight, feed intake, mortality, daily egg production, and FCR). The best dose of selenium was shown in treatment three (commercial feed + organic selenium dose of 150 grams/ton of inorganic selenium feed + vitamin E dose of 1000 grams/ton of feed). The presence of selenium and vitamin E given as additional feed for laying hens can increase egg weight, egg production, minimize mortality rates, and increase appetite.

Selenium, Zinc and Probiotics Ameliorate the Effect of High Ambient Temperature: A Review

/in /by

The exhibition, wellbeing, and prosperity of domesticated animals are firmly affected by environment. Higher encompassing temperature and stickiness are natural stressors that cause weight on animals. Then again, heat pressure is the central point in decreasing animals’ creation, propagation and resistance. Minor components like Selenium (Se) and Zinc (Zn) are fundamental for keeping up with wellbeing and resistance and assume a significant part in cancer prevention agent safeguard and invulnerability capacity and they are engaged with development, creation and generation and go about as cofactors of proteins which are vital to the insusceptibility of creature. Besides, probiotics are basically living microorganisms that, when applied in adequate amounts, give the host medical advantages and affect have creatures. Accordingly, the motivation behind this survey was to evaluate that Selenium, Zinc and probiotics further develop Animal wellbeing, cell reinforcement status and safe Function raised under high surrounding temperature.
