TLDR
A total of 92 samples of street dust were collected in Luanda, Angola, were sieved below 100 μm, and analysed by ICP-MS for 35 elements after an aqua-regia digestion as discussed by the authors.About:

A review of heavy metal contaminations in urban soils, urban road dusts and agricultural soils from China.
Binggan Wei,Linsheng Yang +1 more
TL;DR: In this paper, the authors reviewed quite a few heavy metal contamination related studies in several cities from China over the past 10 years and discussed the concentrations, sources, contamination levels, sample collection and analytical tools of heavy metals in urban soils, urban road dusts and agricultural soils.
Journal ArticleDOI
Contamination features and health risk of soil heavy metals in China
TL;DR: The results showed that, due to the drastically increased industrial operations and fast urban expansion, Chinese soils were contaminated by heavy metals in varying degrees and children and adult females were the relatively vulnerable populations for the non-carcinogenic and carcinogenic risks.
Journal ArticleDOI
Health risk assessment of heavy metal exposure to street dust in the zinc smelting district, Northeast of China.
TL;DR: The ingestion of dust particles of children and adults in Huludao city appears to be the route of exposure to street dust that results in a higher risk for heavy metals, followed by dermal contact, according to the calculation on Hazard Index (HI).
Journal ArticleDOI
The uptake and bioaccumulation of heavy metals by food plants, their effects on plants nutrients, and associated health risk: a review.
TL;DR: Consumption of vegetables grown on metal-contaminated soil were nutrient deficient and consumption of such vegetables may lead to nutritional deficiency in the population particularly living in developing countries which are already facing the malnutrition problems.
Journal ArticleDOI
Risk-based evaluation of the exposure of children to trace elements in playgrounds in Madrid (Spain).
TL;DR: Risks associated with the estimates of toxicity values and exposure factors should be reduced before any definite conclusions regarding potential health effects are drawn, risk assessment has proven to be a very useful tool to identify the contaminants and exposure pathways of most concern in urban environments.

Trace Elements in Soils and Plants
Iain Thornton,John S. Webb +1 more
TL;DR: In this paper, the essential roles of arsenic, fluorine, nickel, silicon, tin and vanadium have in recent years been established in animal nutrition, and they are known as trace elements, minor elements or micro-nutrients.

Statistical Methods for Environmental Pollution Monitoring
TL;DR: In this paper, the authors proposed three-stage sampling: simple random sampling, two stage sampling and three stage sampling, and two-stage and double sampling, respectively, to estimate the mean and variance from censored data sets.
