Although biomonitoring has been used in many occupational and environmental health and exposure studies, we are only beginning to understand the complexities and uncertainties involved with the biomonitoring process--from study design, to sample collection, to chemical analysis--and with interpreting the resulting data. We present an overview of concepts that should be considered when using bio...

In this study, we re-assess the use of bivalve shells as a proxy of lead pollution. Previous studies have stressed that shells display little variability compared to soft tissues and thus are better for pollution biomonitoring. However, in this manuscript we illustrate that there is large inter- and intra-annual Pb variability between shells of the clam Mercenaria mercenaria collected in North ...

The European Water Framework Directive 2000/60/EC (WFD) has been implemented over the past 20 years, using physicochemical, biological and hydromorphological elements to assess ecological status of surface waters. Benthic diatoms (i.e., phytobenthos) are one most common quality (BQEs) used in water monitoring particularly successful detecting eutrophication, organic pollution acidification. Her...

Air pollution is a major concern throughout the universe due to effects on living and non-living things. Before an area said be polluted, there need carry out bottom-up or top-down assessment of environment. Mosses have been widely employed as cheap bioindicators atmospheric pollution. It reduces time-frame spent in monitoring results are reliable. Several types research undertaken spatial temp...

soils bacteria are frequently faced with various adverse environmental conditions and have developed a complex regulatory network to respond rapidly to environmental changes. in this study usefulness and applicability of stress proteins of bacteria which are produced after stress conditions were examined. the adaptation of soil bacteria involves the induction of stress proteins provide a nonspe...
