The accumulation of plastic debris in pelagic habitats of the subtropical gyres is a global phenomenon of growing concern, particularly with regard to wildlife. When animals ingest plastic debris that is associated with chemical contaminants, they are at risk of bioaccumulating hazardous pollutants. We examined the relationship between the bioaccumulation of hazardous chemicals in myctophid fis...

A cross-sectional survey was conducted to understand the extent of occupational injuries and the perception of hazards among the road-side welders in the city of Karachi. Burns and foreign body in eyes were reported to be the most common injuries. Few workers perceived their occupation as hazardous. Consequently, few of them reported using protective measures. A 3-step strategy was recommended ...

In Québec, workers intervening in hazardous zones of machines, equipment and processes during maintenance, repairs and unjamming activities have to apply lockout procedures. Lockout procedures involve shutting down the equipment, isolating it, applying individual locks, releasing residual energies and verifying the absence of energies. Lockout has mostly been linked to industrial sectors. Howev...

PURPOSE The study aims to classify schools based on traffic pollutants and their complex sources, to assess the environment, to determine the state of allergic diseases among students using the International Study of Asthma and Allergies in children (ISAAC) questionnaire, and to assess their connection to air pollutants. MATERIALS AND METHODS A total of seven schools were divided into three c...

The transportation of dangerous goods by road is the most accident-prone mode transportation, even if accidents involving are considered as a Low Probability and High Consequence event (LPHC event). However, several transported networks, such petroleum products chemicals, which can generate major consequences spills, explosions, fires, or toxic clouds. In this context, article presents method t...

This Project focuses mainly on road accidents occurring due to poor indication of sign boards, drowsy state and drunken state of drivers in both two wheelers and four wheelers. The eye blink sensor detects the drowsy state and alarms the driver using buzzer .The alcohol sensor detects the alcohol from breath and stops the engine by micro controller immediately .The light sensor detects the inte...

This paper describes the application of multiobjective heuristic search algorithms to the problem of hazardous material (hazmat) transportation. The selection of optimal routes inherently involves the consideration of multiple conflicting objectives. These include the minimization of risk (e.g. the exposure of the population to hazardous substances in case of accident), transportation cost, tim...
