BACKGROUND An outbreak of serogroup C meningococcal disease (MD) that involved employees from an oil refinery occurred in Paulínia, from March to June 2010, and spread to the community of Cosmópolis, both situated in São Paulo State, Brazil. The aim of this study was to describe the epidemiological and laboratory aspects, and the control measures that were implemented. METHODS Descriptive and...

OBJECTIVES The purpose of this retrospective cohort study was to investigate the relationship between exposure of Korean workers to petrochemicals in the refinery/petrochemical industry and lymphohematopoietic cancers. METHODS The cohort consisted of 8,866 male workers who had worked from the 1960s to 2007 at one refinery and six petrochemical companies located in a refinery/petrochemical com...

BACKGROUND Community concern about asthma prompted an epidemiological study of children living near a petrochemical refinery in Cape Town, South Africa. Because of resource constraints and the complexity of refinery emissions, neither direct environmental measurements nor modelling of airborne pollutants was possible. Instead a meteorologically derived exposure metric was calculated with the re...

The present work examined data obtained during the analysis of Hearing Reduction (HR) of Abadan Petroleum Refinery (Abadan PR) workers of Iran with a history of disease and injuries. To this end, all workers in the refinery were chosen. In this research, the effects of history of disease and injury including trauma, electric shock, meningitis-typhoid disease and genetic illness as well as conta...

Crude oil distillation (atmospheric distillation column with furnace) consumes about 50% of the energy required in oil refinery plant. To achieve further reduction of the energy required in oil refinery plants, it is required to investigate the crude oil distillation and to retrofit it for energy saving process. Recently, authors developed an innovative process design technology, self-heat recu...

background heat, chemical and organic pollution are three types of environmental pollution, caused by refinery and petrochemical industries. problems caused by hear and chemical pollutants are currently resolved to some extent but organic pollution such as poly aromatic hydrocarbons (pahs) are still considered as important problems of industry and environment. objectives a laboratory study was ...
