“…Among marine organisms, bivalves gained global importance as bioindicators and have been extensively used in biomonitoring programs of coastal waters (Maranho et al, 2015a(Maranho et al, , 2015bPereira et al, 2014;Aguirre-Martínez et al, 2013;Martín-Díaz et al, 2007). These organisms have broad geographical distribution, availability in the field and through aquaculture production, as well as suitability for laboratory and in situ experiments (Maranho et al, 2015c;Cajaraville et al, 2000).…”

Our study aimed to evaluate crack cocaine effects in different life stages of the marine mussel Perna perna. For this purpose, fertilization rate, embryo-larval development, lysosomal membrane stability and DNA strand breaks were assessed. Effect concentrations in gametes and in larval development were found after 1h (IC=23.53mg·L) and 48h (IC=16.31mg·L), respectively. The highest tested concentration showing no acute toxicity (NOEC) was 10mg·L, while the lowest observed effect concentration (LOEC) was 20mg·L. NOEC concerning embryo-larval development was 0.625mg·L, while the LOEC was 1.25mg·L. Cyto-genotoxic effects were evidenced in mussels exposed to crack cocaine concentrations ranging from 5 to 500μg·L. Our results report the first data on effects of an illicit drug to marine organisms and should encourage further ecotoxicological studies of these contaminants of emerging concern in coastal ecosystems.

“…The wastewaters contain heavy metals, oil and grease, insecticides, pesticides, PAHs, steroids, surfactants, nutrients, pharmaceutical, personal care products and pathogens. These compounds cause biochemical and immunochemical responses and functional changes at cellular levels of filter feeder organisms of the benthic communities [8,37,38,39,40]. Particularly, fecal pathogens such as Escherichia coli, Salmonella, Shigella and Klebisella, contaminated up to 30 cm of sediment environment and accumulated highly in the benthic biological communities increasing mortality and morbidity rates in the coastal marine ecosystem [41].…”

The present investigation is focused on the forecasting visual observation of the impact of anthropogenic activity on the pilgrimage places located along the coastal environments in Tamil Nadu, India. Devotees performing the unregulated ritual ceremonies, open defecation, waste materials dumping and local municipality discharging wastewater contamination levels were assessed from direct visual surveillance, and by taking photographs and baseline information collected from five different pilgrimage sites. Results showed that ritual ceremonies, wastewater discharges and debris highly contaminated site-III, and found open defecation at site-I. The lack of coastal regulation, pollution awareness, insufficient sanitation facilities and failure to control the commercial and recreational activities have major deleterious effects on the present and future environments of the coastal areas. This is the first attempt conducted by visual assessment of the coastal pollution in pilgrimage places. The results immensely support the recommendation for proper regulation of ritual activities, arrangement of basic sanitation facilities and prohibition of wastewater discharges to prevent waterborne diseases as well as to strictly follow the regional and national level of coastal regulation policy to protect the biological resources of the Gulf of Mannar marine ecosystems.

To evaluate the applicability of cellular energy allocation (CEA) in the bivalves as a biomarker for the assessment of environmental contamination, the energy contents and energy consumption in several tissues of the Manila clam, Ruditapes philippinarum were analyzed. The contents of lipid, glucose, protein and electron transport system (ETS) activity in the foot, siphons, gills, and body of R. philippinarum exposed to crude oil-spiked sediments were measured at 1, 2, 4, 7, 10 days after exposure. The reserved energy (energy available, EA) in the lipid, glucose and protein decreased as contamination level and exposure time increased. In contrast, the ETS activity (energy consumed, EC) showed the reverse tendency. The order of available energy contents were foot > siphons > gill > body. Significant differences in both EA and EC were found only at the highest contamination level (58.3 mg TPAHs/kg DW). EA decreased significantly in the foot and gill at 1 day, in the body at 2 and 7 days after exposure. EC increased significantly in the body at 4 days after exposure. CEA showed higher sensitivity to the contamination than EA or EC. Especially, CEA in the foot and body decreased significantly at lower ranges of contamination level (as low as 6.5 mg TPAHs/kg DW) during 1 to 7 days after exposure. The CEA is more useful than EA or EC alone for the assessment of sediment contamination at lower level that acute toxicity could not be detected. CEA analyses in the body of R. philippinarum after 4 days' exposure to contaminated sediments seem to be the most sensitive and reliable.
