The environmental risks associated with heavy metal pollutions are becoming worrisome. Hence, this study evaluated the and human health of lead (Pb) accumulation in soil samples from solid waste dumpsites within Abuja, Nigeria. Soil (n=72) were collected (0-45 cm depth) Abaji, Bwari, Gosa, Gwagwalada, Kuje, Kwali 2 km away (control), then analyzed for Pb using atomic absorption spectrophotomete...

BACKGROUND Anthropogenic re-distribution of lead (Pb) principally through its use in gasoline additives and lead-based paints have transformed the urban exposome. This unique study tracks urban-scale soil Pb (SPb) and blood Pb (BPb) responses of children living in public and private communities in New Orleans before and ten years after Hurricane Katrina (29 August 2005). OBJECTIVES To compare...

Background:The use of herbal or medicinal plants in various forms has been popular for thousands of years. It is estimated that about 70–80% of the world’s population relies on alternative medicine, mainly of herbal origin. However, due to the nature and sources of these plants, they are sometimes contaminated with toxic heavy metals, which pose serious health risks to consumers. Herbal formula...

This commentary considers the long arc of lead (Pb) poisoning from antiquity to 21st century. While Pb exposure is commonly attributed paint or water, this article aims discuss underrecognized impacts air and soil address controversial misconceptions related these sources. The Roman Aristocracy experienced mainly ingestion foods, cookware, lead-contaminated water wine, but by 20th century, occu...

Heavy metal poisoning is one of the common problems that occurs due to changes in food chain, environmental conditions, etc., One of the most commonly occurring toxicities due to metal ions is lead poisoning. It causes many diseases like skin lesions, cancer, diabetes, heart and lung related problems etc., in human beings. It was widely reported that the elevated level of Pb (II) in drinking wa...

Resource utilization of SO2 from flue gas is a key challenge for the green development smelting industry. Recovery sulfur resources in form elemental (S0), which has high market demand and current focus field treatment, can reduce solid waste desulfurization. In this study, it was found that Pb as cathode material had good catalytic activity electrochemical reduction selectivity towards sulfur....

The current investigation aimed to examine the present status of pollution in Bhima River using indices (degree contamination, heavy metal evaluation index, & index) and health risk assessment (non-carcinogenic carcinogenic) by choosing some metals like copper (Cu), chromium (Cr), manganese (Mn), cadmium (Cd), nickel (Ni), lead (Pb), zinc (Zn). Eight samples surface water were collected mon...

The existence of ancient rocks in present mid-ocean ridges have long been observed but received less attention. Here we report the discovery of zircons with both reasonably young ages of about 5 Ma and abnormally old ages of approximate 180 Ma from two evolved gabbroic rocks that were dredged from the Southwest Indian Ridge (SWIR) in the Gallieni fracture zone. U-Pb and Lu-Hf isotope analyses o...

Introduction Let C be a convex bounded body in the n-dimensional Euclidean space E, and let B be its boundary. We use Busemann's notations: E(a,b) for the segment {(1 — p)a + pb: 0 < p ^ 1} from a to b, and S(z, p) for the sphere {x: \\z — x\\ = p). We now recall the definition of Hammer's associated bodies C(r). Let Cb(r) be the set obtained from C by a similitude transformation with a ratio r...

A breeding population of the common toad Bufo bufo living in the vicinity of a Zn-Pb smelting works in Bukowno, Poland was studied for the presence of thallium. Tl concentration was measured in the bottom sediments of the spawning pond, in the laid eggs, in juveniles after metamorphosis, and in the selected tissues of the adult individuals. A very high concentration of Tl was detected in the sp...
