Background: Benzene exposure is one of the main health concerns for high risk occupations like petrol pump workers. But there is little knowledge about the effect of benzene metabolites on blood parameters. Aims & Objective: The objective of this study is to find out the effect of benzene exposure on hematological parameter especially eosinophil count on petrol pumps workers. Materials and Meth...

In the Petrol Station Replenishment Problem (PSRP) the aim is to jointly determine an allocation of petroleum products to tank truck compartments and to design delivery routes to stations. This article describes an exact algorithm for the PSRP. This algorithm was extensively tested on randomly generated data and on a real-life case arising in Eastern Quebec.

Abstract: In this paper we introduce the Periodic Petrol Station Replenishment Problem (PPSRP) over a T-day planning horizon and describe four heuristic methods for its solution. Even though all the proposed heuristics belong to the common partitioning-then-routing paradigm, they differ in assigning the stations to each day of the horizon. The resulting daily routing problems are then solved ex...

mankind efforts for achieving a better life while brings welfare for him, unfortunately brings environmental and harmful effects on health. these harm specially the ones due to increase in automobiles and fossil fuels, endanger the possibility of the continuation of life for present and future tenerations. lead is mentioned as one of the outputs of these fuels. available studies indicate that t...
