In Western Australia, the discharge of drill cuttings at sea is permitted under certain conditions set by regulatory authorities. These drill cuttings are coated with the drilling muds used during the drilling process. Synthetic-based drilling muds (SBMs) are increasingly used in exploration drilling. However, very little is known of their long-term toxicity in the marine environment. The impetus for the present study arose from the concerns raised regarding the long-term environmental impacts of SBMs on marine biota. The project investigated the chronic toxicity of two SBMs, Syndrill 80:20 and Syndrill 90:10, to a marine fish, the pink snapper (Pagrus auratus Forster). Juvenile fish were exposed under laboratory conditions to the two SBMs for 21 days, after which biomarkers of exposure (ethoxyresorufin-O-deethylase [EROD] activity and biliary metabolites) and biomarkers of effects (condition factor, liver somatic index, serum sorbitol dehydrogenase [SDH], DNA damage and heat shock stress proteins HSP-70)...
在西澳大利亚州，在监管机构规定的某些条件下，允许在海上排放钻井岩屑。这些钻屑被钻井过程中使用的钻井泥浆覆盖。合成基钻井液(sbm)在勘探钻井中的应用越来越广泛。然而，人们对它们在海洋环境中的长期毒性知之甚少。开展本研究的动力来自于人们对水生生物对海洋生物群的长期环境影响的关注。该项目调查了两种SBMs, Syndrill 80:20和Syndrill 90:10，对海洋鱼类，粉红鲷鱼(Pagrus auratus Forster)的慢性毒性。在实验室条件下，幼鱼暴露于两种SBMs 21天，之后暴露的生物标志物(乙氧基间苯二酚- o -去乙基化酶[EROD]活性和胆道代谢物)和影响的生物标志物(条件因子、肝脏体细胞指数、血清山梨醇脱氢酶[SDH]、DNA损伤和热休克应激蛋白HSP-70)…

This contribution is part of a more extensive assessment of the effects of air pollution in urban environments in Patagonia (Argentina) through its effects on the lichen flora. Different methodologies were applied. This paper presents calculations of the Index of Atmospheric Purity (IAP) for urban contaminated (Bariloche city) and periurban uncontaminated environments, calculated at sites for which data were available on the elemental composition of contaminating elements. The IAP results obtained were correlated with the elemental composition of lichen thalli. Principal Component Analysis and Cluster Analysis were performed to determine data partitioning using Ward's method. The results yielded four clusters: three of them correspond to thalli and IAP values from urban areas, where the most important factors affecting the lichen flora have been identified as their proximity to medium to high traffic density or petrol stations. Thalli from periurban uncontaminated environments form an independent cluster,...

Governmental agencies, Tribal Nations, scientists, managers, and the public are interested in assessing the health of ecosystems and their component parts, including humans. Assessing and monitoring human and ecosystem health requires the use of a suite of bioindicators that are biologically, methodologically, and societally relevant, and can be used effectively over time to assess trends and provide early warning. Often the latter consideration is ignored, or at best assumed. This paper examines the role of stakeholders in indicator selection specifically, and suggests that societal relevance should include participation and collaboration with a full range of Tribal Nations and stakeholders, as well as federal and state agencies. The inclusion of a full range of Tribal Nations and stakeholders can result in the development of bioindicators useful for ecosystem health assessment, human effects and interventions, human health assessment, evaluating the efficacy of remediation, and evaluating sustainability...

Freshwater inflow is an important source of physical variability in estuaries. Effects of water flow are dynamic, and it is impossible to sample all conditions as they vary over space and time. Benthos, however, are fixed in place, continuously sample the overlying water conditions, and demonstrate a variety of consistent responses to multiple sources of stress. Benthic indices of biotic integrity (BIBIs) have been particularly useful for assessing aquatic systems. However most indices have focused on assessing effects related to changes in water quality rather than water quantity. This study develops a Freshwater Inflow Biotic Index (FIBI) to determine how changes in freshwater inflow affect benthic populations, which in turn reflect the ecological condition of an estuary. Based on benthic succession theory and long-term data, 12 biotic metrics were chosen that characterized benthic community structure in response to inflow regimes. The metrics were ranked and then reduced to one variable using principal...

The fields of ecology and evolution vs. environmental science were once separate. This was to differentiate between the processes of natural selection and adaptation occurring in natural environments vs. those in which humans were consciously altering their environment, affecting their adaptation to that environment and thus their own evolution. Today, the fields of ecology, evolution, and environmental science are intimately linked, because all known ecosystems on earth have been affected by human activities. Those effects are now being documented back hundreds to thousands of years. Environmental indicators are used to sense levels of disturbance, primarily anthropogenic, to systems and also to monitor their recovery from such. The issue of whether climate change and global warming is a natural or anthropogenic phenomenon has been debated for decades. Now it is widely accepted as being a human-induced phenomenon linked to our society's introduction of increasing amounts of greenhouse gases, particularly...

We analyzed weighted prevalence of various parasites and pathologies for 1995 to 2006 along with a set of physiological variables to determine the degree of concordancy in their interannual variations over 500-km stretches of coastline using data from the National Oceanic and Atmospheric Administration's (NOAA's) National Status and Trends “Mussel Watch” Program. The variables examined in mytilid mussels fell into three groups based on the temporal patterns observed: ceroid bodies, taxon richness, digestive tubule atrophy, and major pathologies varied concordantly along the Northeast and West Coasts. For reproductive stage, sex ratio, and gill ciliates, concordant temporal trends were limited to the northeast coast. Gregarines, found only in West coast mussels, behaved similarly to those variables falling into the first group. A final group, trematode metacercariae and sporocysts, tissue pathologies, and the prokaryotes, was characterized by limited concordancy. For oysters, a similar triplet of groups wa...

Increased sea-surface temperatures (SSTs) associated with climate change/global warming have caused bleaching in scleractinian corals (the loss of obligate symbiotic zooxanthellae) on a global basis, resulting in mass mortality of corals and decimation of reefs. This symbiotic relationship makes these corals an excellent bioindicator of climate change. It has been hypothesized that bleaching is a mechanism by which corals can adapt to changing environmental conditions via the “shuffling” of symbiont clades and acquisition of better-adapted symbionts. Experimental research has confirmed that zooxanthellae are sensitive to increases in seawater temperatures, exhibiting apoptosis (a form of programmed cell death) at temperatures of ≥30οC while in situ. The coral hosts, however, tolerate experimental temperatures up to 34οC, not showing signs of apoptosis and necrosis until 36οC. Thus, zooxanthellae currently appear to be poorly adapted to temperature increases, while the corals are resistant to higher temper...

Polyaromatic hydrocarbons (PAH's) are the prominent and most common pollutants in aquatic environments, particularly in marine water. The discharge of hydrocarbons into the sea might be of great concern for marine species living close to dumping sites. Therefore, toxicological properties of hydrocarbons released into marine environments need to be evaluated. PAH pollution potential may be predicted by assessing the induction of hepatic cytochrome P450-associated enzyme activity. The inducibility and activity of phase I reduction nicotinamide adenine dinucleotide phosphate, reduced (NADPH) cytochrome c reductase (CCR), cytochrome c oxidase (COX) and three CYP450 isoforms (benzyloxyresorufin - O-dealkylase [BROD], ethoxyresorufin-O-dealkylase [EROD] and methoxyresorufin-O-dealkylase [MROD] ) enzymes were measured in the hepatic S9 fraction prepared from Perna viridis collected from three sites: a highly oil-polluted site (Kasimedu fishing harbor, Rayapuram, Chennai [Station1]); a moderately polluted off-sho...
多芳烃(PAH’s)是水生环境中最重要和最常见的污染物，特别是在海水中。向海中排放碳氢化合物可能对生活在倾倒地点附近的海洋物种造成严重影响。因此，需要对释放到海洋环境中的碳氢化合物的毒理学特性进行评估。通过评估肝细胞色素p450相关酶活性的诱导，可以预测多环芳烃的污染潜力。测定了从三个地点采集的绿枝海参肝脏S9组分中ⅰ相还原烟酰胺腺嘌呤二核苷酸磷酸、还原性(NADPH)细胞色素c还原酶(CCR)、细胞色素c氧化酶(COX)和3种CYP450同工型(苄氧基间苯二酚- o -脱烷基酶[BROD]、乙氧基间苯二酚- o -脱烷基酶[EROD]和甲氧基间苯二酚- o -脱烷基酶[MROD])的诱导性和活性:一个高度石油污染的地点(金奈Rayapuram的Kasimedu渔港[Station1]);一个中度污染的郊区……
