“…2). This result was consistent with an earlier oil toxic test (Harris et al, 1977), which shows a significant positive correlation between copepod tolerance and body size measured as dry weight and total lipid content. Jiang et al (2009a) have also found a positive relationship between the LC 50 and body size, signifying that small-bodied copepods (e.g., P. aculeatus, A. pacifica, and A. spinicauda) are more sensitive to residual chlorine than large-bodied ones (e.g., C. sinicus, L. euchaeta, E. subcrassus, and E. concinna).…”

“…1). This finding agreed with a previous study suggesting a negative correlation between copepod retention and temperature (Harris et al, 1977). Similarly, as reported in the acute toxicity test of Hansen et al (2011) wherein two closely related and morphologically similar copepod species are compared, the Arctic copepod (Calanus glacialis, adapted to 2 C) appears less sensitive than the temperate-boreal species (Calanus finmarchicus, adapted to 10 C).…”

“…However, toxicity data on the effects of oil pollution on coastal copepods do not take into account many different species. Few studies have considered seasonal and species-specific differences, and little is known about the effects of acclimatization temperature and body size of marine copepods on oil pollution (Harris et al, 1977).…”

“…The males did not increase their level of total lipid: indeed, there was a 50% decrease in their wax ester content. From the time sequence of the entire experiment referred to in Table 2 it is likely that the stage Vs had developed into adults shortly after the start of the final feeding period; the results are thus explained by the known fact that females feed much more actively than males on Biddulphia cells (Harris et al 1977). I* 1& c^ear from Table 2 that stage Vs deposit large amounts of lipid that is predominantly wax esters, whereas adult females deposit smaller amounts of lipid that is composed of both wax esters and triglycerides.…”

Many of the calanoid copepods contain large amounts of neutral lipid that is predominantly wax esters (Lee, Hirota & Barnett, 1971; Lee & Hirota, 1973; Sargent & Garten, 1976). The role of these compounds in the life-history of copepods is particularly well documented for the large Northern Pacific calanoid Euchaeta japonica Marukawa. These animals have their highest levels of total lipid (50% of the dry weight) at stage V, up to 80% being wax esters (Lee, Nevenzel & Lewis, 1974). Wax ester levels are lower in adult females but are high in the eggs, the contents of which are subsequently used during the naupliar stages (Lee et al. 1974). Thus, wax esters accumulated during the later developmental stages provide a fuel for the developing eggs and embryos; from which it follows that the amounts of these lipids present in mature animals are likely to be critical in determining the brood size and survival of the ensuing generation. So far, however, the factors controlling lipid levels in copepods have been poorly understood.

“…PAHs. Previous studies have not been able to resolve the relative importance of these two processes [11], although there also is indirect evidence that copepods can metabolize PAHs compounds [46,47]. Lacking values for Galveston Bay, we have utilized values in [48] for Neocalanus, a planktonic copepod sampled near Port Valdez, Alaska (mean = 0.051, range of 0.09 to 0.192 ug PAHs g -1 wet weight), with a mean wet weight biomass of individual stage 5 copepodites of 2.3 mg per individual.…”

Polycyclic aromatic hydrocarbons (PAHs) cycling and fates in Galveston Bay, Texas, USA

et al. 2020

The cycling and fate of polycyclic aromatic hydrocarbons (PAHs) is not well understood in estuarine systems. It is critical now more than ever given the increased ecosystem pressures on these critical coastal habitats. A budget of PAHs and cycling has been created for Galveston Bay (Texas) in the northwestern Gulf of Mexico, an estuary surrounded by 30–50% of the US capacity of oil refineries and chemical industry. We estimate that approximately 3 to 4 mt per year of pyrogenic PAHs are introduced to Galveston Bay via gaseous exchange from the atmosphere (ca. 2 mt/year) in addition to numerous spills of petrogenic PAHs from oil and gas operations (ca. 1.0 to 1.9 mt/year). PAHs are cycled through and stored in the biota, and ca. 20 to 30% of the total (0.8 to 1.5 mt per year) are estimated to be buried in the sediments. Oysters concentrate PAHs to levels above their surroundings (water and sediments) and contain substantially greater concentrations than other fish catch (shrimp, blue crabs and fin fish). Smaller organisms (infaunal invertebrates, phytoplankton and zooplankton) might also retain a significant fraction of the total, but direct evidence for this is lacking. The amount of PAHs delivered to humans in seafood, based on reported landings, is trivially small compared to the total inputs, sediment accumulation and other possible fates (metabolic remineralization, export in tides, etc.), which remain poorly known. The generally higher concentrations in biota from Galveston Bay compared to other coastal habitats can be attributed to both intermittent spills of gas and oil and the bay's close proximity to high production of pyrogenic PAHs within the urban industrial complex of the city of Houston as well as periodic flood events that transport PAHs from land surfaces to the Bay.
