Seaweeds are well known to concentrate metals from seawater and have been employed as monitors of metal pollution in coastal waters and estuaries. However, research showing that various intrinsic and extrinsic factors can influence metal accumulation, raises doubts about the basis for using seaweeds in biomonitoring programmes. The thallus of brown seaweeds of the order Laminariales (kelps) is ...

lichen species (hypogymnia physodes and evernia prunastri) were used for biomonitoring thepossible air pollution with heavy metals in the vicinity of copper mine in the eastern part of the republic ofmacedonia. the contents of 18 elements were analysed by icp-aes and etaas techniques. for dataprocessing basic statistical methods and multivariate exploratory (factor and cluster analysis) techniq...

the present study was focused upon the assessment of acetyl-cholinesterase (ache) activity in the digestive gland (main metabolic center) and foot (highly innervated organ) of the green garden snail, cantareus apertus (born, 1778), exposed to different nominal dietary concentrations of pb (25 and 2500 mg pb/kg), cd (10 and 100 mg cd/kg) and their combination (25 mg pb + 10 mg cd/kg and 2500 mg ...

Pesticides are widely used around the world, and hundreds of millions of people are exposed annually in occupational and environmental settings. Numerous studies have demonstrated relationships between pesticide exposure and increased risk of cancers, neurodegenerative and neurodevelopmental disorders, respiratory diseases and diabetes. Assessment of genotoxicity of pesticides and biomonitoring...

Biologic monitoring (i.e., biomonitoring) is used to assess human exposures to environmental and workplace chemicals. Urinary biomonitoring data typically are adjusted to a constant creatinine concentration to correct for variable dilutions among spot samples. Traditionally, this approach has been used in population groups without much diversity. The inclusion of multiple demographic groups in ...
