To investigate the effects of rapid urbanization on water pollution, quality, daily unit area pollutant load, quality score, and real-time index for Jinwi River watershed were assessed. The contribution known pollution sources was identified using multivariate statistical analysis absolute principal component score-multiple linear regression. data collected during dry wet seasons to compare cha...
as opposed to the staining of non-cultivatable organisms of these two genera. Cotton gauze and rayon-polypropylene fiber swabs were equally sensitive for collecting salmonellae from the streams examined. Tetrathionate enrichment incubated at 41.5 C appeared to be superior to selenite-cystine for isolation of salmonellae from surface waters. Twenty-eight serotypes of Salmonella and two serotypes...
the effect of microbial load on the condition index of the edible oyster, saccostrea cucullata were analysed on monthly basis during 2010 and 2011 from the three different stations (namkhana, frasergaunge and sajnekhali) of indian sundarbans. the results showed significant variation with respect to microbial load between stations and seasons, which is reflected in the tissue of edible oyster. s...
High concentrations of heavy metals in street dust are considered to be a serious risk to the human health and the environment. In this study, 30 dust samples were collected from the pavements in the main streets of Abadan to determine the level of pollution of heavy metals in the street dust. Heavy metal concentrations were analyzed by inductively coupled spectroscopy (ICP-OES) method. The lev...
Understanding the effects of pollutants on the genome is of crucial importance to preserve the evolutionary potential of endangered natural populations. The highly vagile European eel (Anguilla anguilla L.) has suffered a dramatic decline in recruitment since two decades, urging for a better understanding of the genetic impact of pollution. Its catadromous life history constitutes a model to as...
A good understanding of urban soils metal contamination and locating their pollution sources due to industrialization and urbanization is important for addressing environmental problems. Urban soil samples near industrial locations in the Greater Toronto Area (GTA), Ontario, Canada were analyzed for metal (Cr, Mn, Fe, Ni, Cu, Zn, and Pb) contamination. Multivariate geo-statistical analysis (cor...
Air pollution is a global environmental issue, and there an urgent need for sustainable remediation techniques. Thus, phytoremediation has become popular approach to air remediation. This paper reviewed 28 eco-friendly indigenous plants based on both the tolerance index (APTI) anticipated performance (API), using level indices evaluate potential of most plant species control. The estimated APTI...
Aquatic environmental deterioration is becoming a serious problem due to rapid urbanization and economic development, particularly in developing countries. As two important components of the aquatic environment, water quality and sediment pollution are widely considered to be concerns; however, they are considered separately in most cases. The relationship between water quality and sediment pol...
