Predictive Risk

In recent years there has been an increase in the contaminations of heavy metals on the environment. Government and private organization have shown their interest in the effect of dietary exposure to several heavy metals. These heavy metals have been implicated in the etiology of many diseases with high risk to humans. Canned tomatoes paste is one of the important health deterioting factors to human health in Ubani-Umuahia, Nigeria. In this study atomic absorption spectrophotometer was used to screen for nine heavy metals concentration in ten different brands of canned tomatoes paste sold at Ubani-Umuahia market in Nigeria. Human risk assessment was calculated using the collated data to evaluate the predictive risk of human health after the consumption of canned tomatoes paste. Results shows that lead and nickel were not detected in all the canned tomatoes. In comparison low concentrations of copper, iron, and manganese were notated but high concentrations of chromium and cadmium were detected in all the tested tomatoes pastes. Cobalt and zinc concentration was notated lower than permissible limit. The daily intake of copper, cobalt, manganese, chromium, cadmium, nickel, iron, zinc and lead were below their tolerable values in canned tomatoes. The predicted lifetime for carcinogens to occur was less than one (<1). Copper, cobalt, iron, and zinc were below the acceptable value for non-cancer risk with HQ <1.The risk of incurring cancer by ingesting canned tomatoes was within the lifetime predicted a range of (1.0E-6 to 1.0E-4). Finds suggest that prolong and persistent consumption of these heavy metals may cause toxicity and consequential heath challenges. J. bio-sci. 28: 1-11, 2020

Trace heavy metals, such as arsenic, cadmium, lead, chromium, nickel, and mercury, are important environmental pollutants, particularly in areas with high anthropogenic pressure. In addition to these metals, copper, manganese, iron, and zinc are also important trace micronutrients. The presence of trace heavy metals in the atmosphere, soil, and water can cause serious problems to all organisms, and the ubiquitous bioavailability of these heavy metal can result in bioaccumulation in the food chain which especially can be highly dangerous to human health. This study reviews the heavy metal contamination in several areas of Pakistan over the past few years, particularly to assess the heavy metal contamination in water (ground water, surface water, and waste water), soil, sediments, particulate matter, and vegetables. The listed contaminations affect the drinking water quality, ecological environment, and food chain. Moreover, the toxicity induced by contaminated water, soil, and vegetables poses serious threat to human health.

Ternary Intermetallic Compound

The galvannealed steel sheets have received ever increased attention because of their excellent post-painting corrosion resistance and good weldability. However, its powdering and flaking tendency during press forming processes strongly impairs its performance. In order to optimize the properties of galvanneal coatings, it is critical to control the reaction rate between solid iron and molten zinc.In commercial galvannealing line, aluminum is added to zinc bath to retard the diffusion rate between iron and zinc by the formation of a thin layer of Al intermetallic compound on the surface of steel at initial hot-dip galvanizing. However, the form of this compound and its transformation are still speculated. In this paper, we report the direct observations of this compound and its transformation.The specimens were prepared in a hot-dip simulator in which the steel was galvanized in the zinc bath containing 0.14 wt% of Al at a temperature of 480 °C for 5 seconds and was quenched by liquid nitrogen.

Micronutrient Intake

Nutrition is important for human health in all stages of life - from conception to old age. Today we know much more about the molecular basis of nutrition. Most importantly, we have learnt that micronutrients, among other factors, interact with genes, and new science is increasingly providing more tools to clarify this interrelation between health and nutrition. Sufficient intake of vitamins is essential to achieve maximum health benefit. It is well established that in developing countries, millions of people still suffer from micronutrient deficiencies. However, it is far less recognized that we face micronutrient insufficiencies also in developed countries.

This study was undertaken to estimate the contribution of meat and meat products consumption to the daily intakes of trace elements (Fe, Zn, Cu, Se), heme iron, and selected B vitamins (thiamine, riboflavin, niacin) in Italy. Meat and meat products were selected on the basis of their consumption frequency reported by the most recent nationwide dietary individual survey carried out in Italy (INN-CA study). The daily intakes of total iron and heme iron were 1.65 and 1.13 mg/person/day. Zinc intake was 3.65 mg/person/day. Beef made the main contribution to iron, heme iron, and zinc daily intakes. Copper daily intake was 107.3 mug/person/day, with meat products provided the highest contribution (40 mug/person/day). Daily intake of selenium (7.14 mug/person/day) was provided mainly by poultry consumption. Thiamine intake was 228 mug/person/day, and meat products were the main source (110 mug/person/day). Riboflavin intake was 136 mug/person/day, with both beef and meat products as the main contributors (40 mug/person/day). Niacin intake was 7.53 mg/person/day, and poultry was the main source (2.28 mg/person/day). Meat and meat products were a valuable source of micronutrients, supplying 47, 48, and 24% of zinc, niacin, and thiamin daily requirements, respectively, and over 10% of iron, copper, selenium, and riboflavin daily average requirement values of the italian RDAs calculated for the population involved in the survey (INN-CA study).
