“…According to Nguyen, et al (2005), a considerable number of significant correlations in the particulate phase of Lake Balaton were observed between Cr and other metals. However, Jain and Sharma (2001) found very strong correlations on similar metals from the Hindon River in India. In addition, it was observed that all particulate trace metals are negatively correlated with the amount of suspended particulate matter that was similar to the trend in Hindon River (Jain and Sharma, 2001), which may be due to a dilution process of permanently suspended matter, loaded in trace metals coupled with the temporary re-suspension of bottom sediments less contaminated by metals (Nguyen, et al, 2005).…”

Strong correlations between Ni and Zn in the SPM and dissolved phases suggest similar partitioning mechanism in Taylor Creek.…”

ABSTRACT:Correlations between trace metals in dissolved and particulate phases, B. bayad and sediments were investigated in five selected sites along Taylor Creek, which lies between longitude 006°17I to 006°21 I E and latitude 05°01 I to 05°05 I N. The degree of correlation between the various metals was different in each of the investigated segments. Between segments, not many significant correlations were recognized. Only Ni and Cd, Mn and Cd, Mn and Ni, and Mn and Pb are correlated in the sediments and in the particulate phase, Fe and Cr, Pb and Cd, and Zn and Ni are correlated, which suggests that the sources are not common for both compartments. Partitioning coefficients (K d ) of trace metals between dissolved and particulate phases are generally low, which is typical for fresh water ecosystems and fairly stable over Taylor Creek all through the seasons. Furthermore, the bio-concentration factors (BCF) of B. bayad were low unlike those of other natural waters. Cluster analysis showed that metal accumulation in the particulate phase differed from those observed in sediments, which also confirms that the pollution of the Creek might be from different sources.

“…Les concentrations de Cd total dissous dans quelques rivières affectées par des rejets miniers acides dans différentes régions du Québec (Canada) atteignaient 6•10 -8 à 2,2•10 -7 M (LEGUAY et al, 2016). Des concentrations élevées en Cd total dissous furent aussi mesurées dans des rivières en milieu urbain en Inde (JAIN et SHARMA, 2001) (≈9•10 -8 M) et en France (MORIN et al, 2007) (≈8,9•10 -7 M). Finalement, des concentrations de Cd total dissous atteignant 10 -6 M ont été mesurées dans des eaux souterraines affectées par le drainage minier acide en Chine (SUN et al, 2013).…”

Lors d'expositions chroniques aux métaux, des interactions physiologiques complexes entre les organismes et les métaux essentiels et non essentiels modulent le taux de transport des métaux et leur toxicité. La présente revue de littérature aborde les récentes avancées en chimie de l'environnement, en biologie moléculaire et en physiologie cellulaire touchant aux mécanismes de régulation du transport membranaire des métaux essentiels chez le phytoplancton eucaryote et leurs impacts sur l'accumulation et la toxicité d'un métal habituellement non essentiel, le cadmium. Cette revue évalue finalement la possibilité d'inclure des éléments de physiologie algale dans la présente version du MLB afin d'améliorer le potentiel de ce modèle à prédire l'accumulation et la toxicité des métaux pour des expositions chroniques. Les résultats disponibles dans la littérature suggèrent que l'inclusion des rétroactions négatives et positives des métaux sur les paramètres cinétiques (V max : vitesse maximale de transport transmembranaire; K M : affinité des transporteurs pour le métal) des multiples systèmes de transport membranaire des métaux a le potentiel d'améliorer les prédictions de l'accumulation et de la toxicité des métaux à long terme chez le phytoplancton. Le développement d'un MLB capable de prédire adéquatement la toxicité chronique des métaux dans des conditions physicochimiques variables représentatives de celles retrouvées en milieu naturel bénéficiera des avancées récentes et futures en toxicologie, biologie et chimie de l'environnement. Ces connaissances pourraient permettre à long terme d'atteindre l'objectif ambitieux d'un MLB capable de réaliser des prédictions fiables à l'intérieur de milieux naturels complexes de différentes compositions chimiques.

“…Hence, in the last few decades, there has been a focus on the deterioration of water quality of Indian rivers. [2,3,4,5,6,7] The heavy metals, which are also called as trace elements found to be the most common environmental contaminant and their occurrence in an aquatic system indicates the presence of natural or manmade pollution. The natural sources of metals in an aquatic system are the weathering of soils and rocks and the anthropogenic sources are industrial and urban wastes which are discharged in water bodies.…”

The Assessment of physico-chemical characters and heavy metal distribution along the Panchganga River, MS India during the period of 2015-16 was carried out by selecting three sites namely, Piral (Upstream), Kolhapur (Midstream), and Narsobawadi (Downstream).The selected five physico-chemical characters such as pH, Electrical Conductivity (EC), Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) were found to be in an increasing trend from Piral to Narsobawadi as well as during Monsoon to summer. The pH was varied from 7.08 to 8.28 which are within BIS permissible limit for surface water i.e. 6.5 -8.5. The electrical conductivity was varied from 220-880 µSiemens/cm for three sites during Monsoon to summer. The DO varied from 2.80 to 5 mg/l, the BOD from 3 to 31 mg/l whereas COD from 10 to 41 mg/l. The Piral site showed good concentration of DO during Monsoon, winter and summer season. The BOD for the Kolhapur during winter and summer and Narsobawadi during Monsoon, winter and summer has exceeded CPCB permissible limit for surface water i.e. 6 mg/l. The site Narsobawadi during summer has exceeded WHO (World Health Organization) permissible limit for drinking water of COD i.e. 10 mg/l. The highly toxic heavy metals such as Lead(Pb), Cadmium(Cd), average toxic metals like Zinc(Zn), Nickel(Ni), Chromium(Cr), Manganese(Mn) and low toxic metal like Iron (Fe) were detected by using Atomic Absorption Spectrophotometer (AAS). The concentration of Fe, Cd and Cr metal has exceeded BIS permissible limit of 0.3 mg/l, 0.01 mg/l and 0.05 mg/l respectively.
