With a profound knowledge of how physico-chemical parameters affect these communities, microbial communities could be used as indicators for environmental changes and for risk assessment studies. We studied aquatic hyphomycete communities in ponds from sites shaped by intense human activities (namely the “Mansfeld region”) and Urmil river, there are no sources of man made effluents in Chhatarpu...

In this study meiobenthic communities were sampled from several acid mine drainage (AMD) impacted sites along the Tioga River in North Central Pennsylvania. Concentrations of several chemical indicators of aquatic health (Fe/Fe, Mn, and SO4) were measured along with the pH. Meiobenthic communities were present at all AMD impacted locations but diversity and abundance varied. The diversity and a...

The research was carried out on broiler-type turkeys of the BUT-9 cross in Republic Mari El and private subsidiary farms. In accordance with our goals objectives, objects were blood serum, red white meat obtained from broiler industrial type cultivation home cultivation. study turkey included: organoleptic studies, tasting evaluation meat, determination chemical physico-chemical composition, en...

Management regimes of varying types and intensities can have profound impacts on grassland soil quality. Plus, there has recently been increased interest in finding soil quality indicators that are reflective of historical and current land management. We surveyed soil quality of privately owned grasslands in northeastern Kansas differing in their cultivation histories and current land-use (cool...

Life indicators, illness characteristics, and psychosocial concomitants were measured in a large sample of persons self-reporting multiple chemical sensitivity. Cross-sectional data are presented for 305 persons who responded to written surveys. Examined are employment status, income, relationship status, illness characteristics such as length, severity, and age respondents became sensitive, mo...

Mercury (Hg) is one of the main chemicals currently altering Mediterranean ecosystems. Red mullet (Mullus barbatus and M. surmuletus) have been widely used as quantitative bio-indicators of chemical contamination. In this study, we reassess the ability of these species to be used as efficient bio-indicators of Hg contamination by monitoring during 18 months Hg concentrations in muscle tissue of...

Soil quality is an evolving concept intended to aid farmers, land managers, researchers, public decisionmakers, and others in the management of soil resources. The central question of soil quality assessment is “how does a soil function?” and a variety of physical, chemical, and biological indicators can be used to address it. This question, however, is complicated by the interdependencies betw...

Input of contaminants is an important pressure in most urbanized coastal areas, but establishing appropriate indicators of their presence and effects has been challenging. Such indicators would, at the very least, have to integrate chemical and biological data. One difficulty has arisen because the measurements provide information on different levels of biological organization (gene level up to...

This paper proposes the construction of tables for emergy synthesis of agricultural systems using internet resources. The general model considered for these tables can be used for simple agricultural systems like chemical farming but also for complex systems as organic, agroecological and forestrycattle-agriculture systems. The construction of tables was possible due to a research on XML (exten...

Pesticides released into the environment may pose both ecological and human health risks. Governments set the regulations and guidelines for the allowable levels of active components of pesticides in various exposure sources, including drinking water. Several pesticide risk indicators have been developed using various methodologies, but such indicators are seldom used for the selection of pesti...
