“…Sand beaches may act as a passive element of cumulative pollution and can become contaminated by garbage, animal waste or water itself carrying pathogenic microorganisms and parasites (Sato et al, 2005). The microbiological context of sediments at the sediment-water interface in bathing waters is receiving increased attention (Arakel, 1995).…”

Whilst the potential impact on beach users from microorganisms in water has received considerable attention, there has been relatively little investigation into microbial contaminants in sand. 33 beaches across Portugal were analyzed during a five year period (2006)(2007)(2008)(2009)(2010) to determine the presence of yeasts, pathogenic fungi, dermatophytes, total coliforms, E. coli and intestinal enterococci in sand.Our results showed that 60.4% of the samples were positive for fungi and that 25.2% were positive for the bacterial parameters. The most frequent fungal species found were Candida sp.and Aspergillus sp., whereas intestinal enterococci were the most frequently isolated bacteria.Positive associations were detected among analyzed parameters and country-regions but none among those parameters and sampling period.Regarding threshold values, we propose 15 cfu/g for yeasts, 17 cfu/g for potential pathogenic fungi, 8 cfu/g for dermatophytes. 84 cfu/g for coliforms, 250 cfu/g for E. coli, and 100 cfu/g for intestinal enterococciHighlights:x 60.4% of the analyzed marine beach sand samples were positive for the studied fungi x Candida sp. and Aspergillus sp. were the most frequent fungal species found x 25.2% of the analyzed marine beach sand samples were positive to the studied bacteria

“…Thus, mercury concentrations in sediments are generally higher and therefore this compartment is considered a sink of mercury and simultaneously a potential source to interstitial waters and to biota, mostly to the organisms that live in contact with the sediments (Arakel, 1995;May et al, 1997). The accumulation of mercury in aquatic organisms has been subject of many studies (Becher and Bigham, 1995;Chapman, 1997;Lawson and Mason, 1998) and it has been observed that the incorporation of Hg in fish depends on metabolic factors and metal bioavailability (Driscoll et al, 1995).…”

“…These include the nature of the beach, tidal phenomena, sewage outlets, the season, the presence of animals and the number of bathers. Water movement, for example, causes erosion, transportation and deposition of beach sediment and redistribution of associated microorganisms [7]. The particular objective of the present study is to scrutinize the seasonal and temporal variations of pollution indicators and to find which source is highly influence the marine environmental contaminations.…”

“…Generally, fecal indicator concentrations are higher in sediments than in the overlaying water column [6]. The microbiological quality of sediments at the sedimentwater interface in bathing water received particular attention [7]. Detection and enumeration of indicator organisms are of primary importance for the monitoring of sanitary and microbiological quality of water [8].…”

In this study, the sea water and sediment samples of four different locations were collected from Palk bay regions during 2014 for pollution indicators study. All the bacterial parameters were higher during the rainy season compared to summer season in all the sampling locations of the Palk bay regions. In the water samples, among the pollution indicator bacterial groups, TC and TS counts were highest 0.67 -10.3 [×10 3 ] ml −1 and 0.8 -10.8 [×10 2 ] ml −1 during monsoon, and the least 0.54 -8.5 [×10 3 ] ml −1 and 0.7 -9.0 [×10 2 ] ml −1 were noticed during summer. In monsoon sediment sample, the higher VC count was observed in Thondi (2100 g −1 ) followed by Mimisal (1700 g −1 ), Manamelkudi (960 g −1 ) and Devipattinam (200 g −1 ). The pollution index (PI) of each location was calculated and was showed a remarkable microbial contamination was observed in sediment sample than water sample. The order of PI observed were Thondi > Mimisal > Manamelkudi > Devipattinam. The highest PI ratio (15.5) was observed in Devipattinam sediment sample at monsoon season while lowest (2.5) was noticed in Devipattinam water sample at summer season. The results indicated that the coastal environment is highly exposed to human excreta that suggesting to avoid direct contact. Hence, throughout impoundment is needed to protect coastal environments.
