Wristwatches, another very frequently used item, showed alarmingly high incidences of free nickel, with around 64% of the specimens testing positive. Wristwatches are potentially more hazardous as the area of skin contact is a lot more and are normally worn daily for prolonged periods. Though not prone to as much skin contact, spectacle frames showed a surprisingly high incidence rate, with hal...

Between 20 to 50 million more people suffer non-fatal injuries, with many incurring a disability as a result of their injury. Road traffic injuries cause considerable economic losses to victims, their families, and to...

Wireless Sensor Networks (WSN) have emerged as a new information-gathering paradigm based on the collaborative efforts of a large number of self-organized sensing nodes. These networks form the basis for many types of smart environments such as smart hospitals, intelligent battlefields, earthquake response systems, and learning environments. A set of applications, such as biomedicine, hazardous...

Abstract We conducted ambient monitoring of various hazardous air pollutants (HAPs) for 2 years (2013-2015) in two adjacent Korean cities a megacity area: Seoul and Incheon. Measured HAPs included volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), heavy metals (HMs). The objectives this study were to evaluate the spatiotemporal variations HAPs, prioritize based on healt...

STUDY OBJECTIVE To determine whether there was a higher incidence of respiratory ill health in children living near to a cement works than in those from a different area, and if so whether the higher incidence was due to the use of a hazardous waste-derived fuel at the works. STUDY DESIGN A sample of the population of children living near the cement works (the study area) was compared with a ...
