Contamination is one of the major problems associated with the environmental sciences. Many of the environmental pollutants affect to the different aquatic animals to certain degree depending on the toxic substance, concentration, self-life and animal behaviour and biology. Direct ingestion of environmental contaminants and bioaccumulation of toxic substances in bivalves, crustaceans, molluscs ...

Environmental concerns over increased coal consumption are fully justified by the past history of coal use. Although improved technology has provided some safeguards, increased utilization will require mining practices, emission control technologies, and waste disposal procedures that are not yet fully integrated into the routine use of the coal energy system. The Committee on Health and Evniro...

The interplay between 'noise-deficient' QSAR and Partial Order Ranking, including analysis of average linear ranks, constitutes an effective tool in giving substances which have not been investigated experimentally an identity by comparison with experimentally well-characterized, structurally similar compounds. It is disclosed that experimentally well-characterized compounds may serve as substi...

A myriad of factors can influence fertility (and the lack there of), which can for instance be impaired by environmental elements, including exposure to toxic substances, but also the maternal and paternal age at the time of conception, the parents’ smoking habits and alcohol intake or genetic defects. The present publication will however focus on the role of nutrition in fertility, more specif...

The use of analytical chemistry measurements in environmental monitoring is dependent on an assessment of measurement error. Models for variation in measurements are needed to quantify uncertainty in measurements, set limits of detection, and preprocess data for more sophisticated analysis in prediction, classification, and clustering. This article explains how a two-component error model can b...
