Biological factors affecting variability of persistent pollutant levels in cetaceans

Natural Mortality Factors Affecting Cetaceans in the Black Sea

Geographic Differences in Persistent Organic Pollutant Levels of Yellowfin Tuna

BACKGROUND Fish are a source of persistent organic pollutants (POPs) in the human diet. Although species, trophic level, and means of production are typically considered in predicting fish pollutant load, and thus recommendations of consumption, capture location is usually not accounted for. OBJECTIVES Yellowfin tuna (Thunnus albacares) are harvested from across the world's oceans and are wid...

Biological factors affecting family size.

Latterly much attention has been attracted, and rightly so, to the number, variety, and potency of the socio-economic factors which strongly incline married couples deliberately to restrain their fertility and thereby to limit the size of-their families. A tendency to overlook a number of purely biological factors which work in the same direction is to be discerned. These latter are for the mos...

Introductory remarks: Session on genetic factors affecting pollutant toxicity.

Occupational and environmental toxicologists are faced with the responsibility of providing sound scientific data that can be used to ensure individuals that they can conduct their daily activities without undergoing any undue risk which might potentiate the development of disease. With the majority of chemicals in the environment, it has been generally assumed that there is some safe level of ...

Factors affecting hospital response in biological disasters: A qualitative study

Background: The fatal pandemics of infectious diseases and the possibility of using microorganisms as biological weapons are both rising worldwide. Hospitals are vital organizations in response to biological disasters and have a crucial role in the treatment of patients. Despite the advances in studies about hospital planning and performance during crises, there are no internationally accepted ...
