“…This is the first report of an adverse effect of such a low calcein concentration on the growth of calcite secreting marine organisms. A similar decrease in size leading to stunted specimens has previously been reported from anthropogenically polluted (See Nigam et al, 2006 for review;Romano et al, 2008;Frontalini and Coccioni, 2011) and naturally ecologically stressed sites as well as in laboratory culture studies (Alve, 1995;Martínez-Colón and Hallock, 2010;Dolven et al, 2013). The large drop in average size of specimens subjected to 20 mg/l calcein, at 25°C after~80 days of incubation, is due to the mortality of all large specimens; only small specimens remained alive.…”

“…Instead of adding new (anomalous) chambers, many of the specimens died. The type of abnormalities, which included chambers of size much larger or smaller than the preceding chambers or newly added chambers being oriented in a plane different than the normal plane of addition of previous chambers, is the same as those noticed in benthic foraminifera from both polluted (see Nigam et al, 2006 for review;Romano et al, 2008;Frontalini and Coccioni, 2011) as well as naturally ecologically stressed environments (range of extreme salinity, temperature, pH) (Boltovskoy et al, 1991;Alve, 1995;Stouff et al, 1999;Geslin et al, 2002;Martínez-Colón and Hallock, 2010;Dolven et al, 2013). Laboratory experiments with pollutants also showed a development of similar abnormal specimens (Saraswat et al, 2004;Le Cadre and Debenay, 2006;Nigam et al, 2009).…”

“…High Pb and Zn concentrations were mainly near Port Blair City, which may be an environmental stress on the foraminiferal populations as evidenced by faunal crop. Species like Honynesiaa germanica, Quinqueloculina parvula and Miliolinella subrotunda, which are usually considered to be pollution-tolerant (Romano et al 2008), were absent in the present study.…”

Anthropogenic impact on Andaman coast monitoring with benthic foraminifera, Andaman Sea, India

The concept of anthropogenic impact is extremely important to be considered while analysing the ecology of coast and shelf zones. For centuries, these zones have been the epicentres for various human activities, including urbanisation, construction of sea ports and harbours, development of natural reservoirs (including oil production and fishing), marine aquaculture, shipping, recreation and many others. Many of the activities in progress on both sides of the shoreline provide 50% or more of the gross State/UT (Union Tertiary) product for surrounding states. The data shows that land-based and atmospheric sources account for about two-thirds of the total contamination found in the marine environment, constituting 44 and 33%, respectively. The greatest anthropogenic pollution pressure undoubtedly falls on the shelf zones and coastal areas. To prove this theory, a total of 25 bottom sediment samples were collected within the depth zone of 5 fathoms from the South Andaman coastal fringe for sediment geochemistry studies and foraminiferal analysis. The samples were further analysed for heavy metal pollutants like Co, Cu, Mn, Pb and Zn. The study yielded 20 benthic foraminiferal species. Of these, five benthic species were living including Ammonia beccarii, Calcarine calcar, Elphidium crispum, Operculina complanata and Nonion deppresula. The presence of deformed specimens and the domination of Ammonia spp. are indications of a polluted environment. Sampled coral reefs had high abundances of Operculina spp. The highest counts of benthic microbiota were found in finer sediment. Species diversity is very limited along the coastal fringe of South Andaman Island in comparison with fauna from the coast of India. This first report of benthic foraminifera from South Andaman Island will allow us to assess future impacts of marine pollution because foraminiferal deformations are positively correlated to the concentrations of heavy metals (Cr, Cu, Mn, Pb and Zn).

“…A. tepida has been considered one of the most tolerant species to high heavy metal concentration and is used as a bio-indicator of pollution of anthropized marine sediments (Ferraro et al, 2006). H. germanica was also considered a bio-indicator of pollution by metals (Frontalini et al, 2011;Romano et al, 2008) and of pollution by metals and hydrocarbons (Armynot du Châtelet et al, 2004).…”

“…The impact of pollution, mainly by heavy metals and organic matter, on benthic foraminifera has been the goal of an increasing number of research lines (e.g., Frontalini et al, 2011;Martins et al, 2010;Carnahan et al, 2009;Romano et al, 2008;Burone et al, 2007Burone et al, , 2006Armynot du Châtelet et al, 2003, Yanko et al, 1999, 1998Alve, 1995Alve, , 1991. Most of these works evaluate the degree of stress caused by pollutants in foraminifera and are based on the total sedimentary elemental concentration of heavy metals.…”

This work evaluates the quality of the sediment in Ria de Aveiro, a coastal lagoon located at N of Portugal that is under strong anthropic influence, and the effects of the contamination on benthic foraminifera. The initial approach for measuring pollution was done through the load pollution index (LPI), based on As, Cd, Cr, Cu, Ni, Pb and Zn concentrations, and determined by total digestion of the sediments (TDS). This information was complemented by conducting a metal fractionation technique (sequential chemical extraction -SCE) in some of the most contaminated samples in order to define the relevance of different metal bearingphases (exchangeable cations adsorbed by clay and co-precipitated with carbonates, absorbed by organic matter and retained in the mineralogical phase) and to evaluate the toxic heavy metal availability. Multivariable statistical analyses were carried out taking into consideration the geochemical results, as well as the biotic (percentage of species/groups of species; foraminifer abundance and diversity) and abiotic variables, such as sediment content in mud, total organic carbon (TOC) and Eh.SCE results show that most of the element concentration in the sediments is retained in the resistant mineralogical phase. However, the higher bioavailability of some toxic elements, such as As, Cd, Cu, Hg, Ni, Pb and Zn, found in Laranjo Bay, Aveiro City, Aveiro Harbours and Espinheiro Channel, have a generic negative impact on benthic foraminifera of the Aveiro lagoon. Differential sensitivity of benthic foraminifera to high concentrations of heavy metals may exist. Quinqueloculina seminulum, for instance, seems to be more tolerant to higher bioavailable concentrations of Pb and Cu than Ammonia tepida or Haynesina germanica. Both
