“…While mosquitofish have superior mouths suggesting a surface-feeding habit, their stomach contents (terrestrial and aquatic invertebrates and algal material) indicate that they feed more opportunistically (Pen et al, 1993). While there is conflicting evidence on the ability of poeciliids to bioconcentrate POPs (Yockim et al, 1978;Gobas, 1990;Ford and Hill, 1991;Freidig et al, 1998) it is possible that they are exposed to them through dietary mechanisms where sediment ΣPCB concentrations are elevated. The TCDDeq in the sediment was not correlated with the hepatic EROD activity suggesting that while some AhR ligands are bioavailable to the fish (through flux or dietary uptake), others may be either unavailable to benthic biota or do not bioconcentrate in them and, therefore, do not enter the food chain.…”

“…They are less commonly used to examine the effects and exposure to POPs. POPexposed poeciliids bioconcentrate 2,3,7,8-TCDD (Yockim et al, 1978;Gobas, 1990) and certain PCB congeners (Freidig et al, 1998) but Ford and Hill (1991) found minimal bioconcentration of OCPs. Their small size, ease of capture and opportunistic feeding regime (Pen et al, 1993) makes them particularly suitable for such use.…”

a b s t r a c tThe site of the 2000 Olympic Games (Sydney Olympic Park (SOP), Sydney, Australia) was contaminated by persistent organic pollutants (POPs) prior to remediation in the 1990s. This study investigates the bioactivity of POPs in the sediment and water of wetlands across SOP by in vitro 2,3,7,8-TCDD equivalence (TCDDeq) measurement (H4IIE cell line bioassay). Further, it examines whether disturbance of these sediments is likely to mobilise ligands for this receptor into the water column. Exposure to aryl hydrocarbon receptor (AhR) ligands was measured in vivo using hepatic cytochrome P4501A (CYP1A) induction (EROD) in the mosquitofish (Gambusia holbrooki). Aqueous TCDDeq ranged from 0.013 to 0.057 pM in SOP wetlands which was significantly (p b 0.05) less that in urban reference sites. These concentrations were not correlated to physical or chemical characteristics of the wetlands. In the sediments, TCDDeq ranged from 0.0016 to 7.06 µg/kg and these were not significantly (p ≥ 0.05) different to that measured in urban reference sites. Simulated disturbance of small quantities of sediment in water samples significantly (p b 0.05) increased the levels of TCDDeq measured in the water. Sediment TCDDeq was correlated to sediment ΣPAH concentration in 2006 and sediment ΣPCB, ΣDDT concentrations and fine sediment grain size in 2005. While fish at one SOP wetland had hepatic EROD activity elevated above the estimated basal level for this species, these were at the lower end of the range measured in urban impacted, non-remediated wetlands. EROD activity was positively correlated with both the sediment ΣPCB load and aqueous TCDDeq. Increased catchment size was correlated with increased EROD activity suggesting an even spread of POPs throughout the residential areas of the Sydney metropolitan area. The concentration of bioactive POPs in the wetlands of SOP is therefore low relative to urban reference sites demonstrating the ongoing success of the remediation program..

“…Levels of organochlorine pesticides, polychlorinated biphenyls and some metals (copper, mercury, selenium, zinc) were examined in blood of diamondback water snakes (Nerodia rhombifer) and blotched water snakes (Nerodia erythrogaster) in Texas (Clark et al, 2000), pesticides in water snakes and cottonmouths from Mississippi (Ford and Hill, 1991), metal concentrations in banded water snakes (Nerodia fasciata) from the SRS (Hopkins et al, 2001), PCBs and organochlorine pesticides in northern water snakes and Lake Erie water snakes (Nerodia sipedon insularum) from the Great Lakes Basin (Bishop and Rouse, 2000), and heavy metals in northern water snakes (Nerodia sipedon) from Tennessee (Burger et al, in press). None of these studies examined three species of aquatic snakes in contaminated and reference sites in both blood and tail snips, although Clark et al (2000) also examined levels in cottonmouths.…”

Abstract. Levels of 18 elements, including lead, mercury, selenium, and uranium, were examined in three species of snakes from an exposed and reference site on the Department of Energy's Savannah River Site in South Carolina. We tested the hypotheses that there were no differences as a function of species, and there were no difference between the exposed and control site for blood and muscle (tail) samples for banded water snake (Nerodia fasciata), brown water snake (N. taxispilota) and cottonmouth (Akistrodon piscivorous). The banded water snakes collected were significantly smaller than the other two species. For blood, there were significant species differences only for barium, copper, selenium, uranium and zinc, while for muscle tissue there were significant interspecific differences in aluminum, arsenic, barium, cobalt, cesium, copper, iron, lead, mercury, manganese, strontium, vanadium and zinc, suggesting that muscle tissue in the tail is a better indicator of potential interspecific differences. It is also easier logistically to collect tail tissue than blood. Where one species had significantly higher levels than the other species in muscle tissue levels, cottonmouth had higherlevels of five elements (aluminum, cobalt, lead, mercury, vanadium), brown water snake had two (lead, strontium), and banded water snake had only barium. There were few significant differences between the control and reference site for levels of blood, but several for muscle tissue. All three species had significantly higher levels of arsenic and manganese at Tim's Branch than the reference site, and nickel and uranium were significantly higher for banded watersnake and cottonmouth, the larger species. Individuals with high exposure of one element were exposed to high levels of other elements.

“…Smith et al [4] determined DDT (0.0001 -0.014 mg/kg) and dieldrin (0.0001 -0.005 mg/kg) residues in sediment samples collected from upper Rockaway Riverine in New Jersey, USA. Also Ford and Hill [6] found that pesticide residues in sediment collected from Yazoo National Wild Life Refuge, Missis- sippi, contained Dieldrin, P,P9-DDE and DDT at levels of 0.00 -0.07, 0.04 -0.1 and 0.11 -0.16 mg/kg wet weight, respectively. Our results revealed that bolty fish samples collected from River Nile contained high levels of pesticide residues for aldrin, DDT, diazinon, parathion and propoxur, followed by boury fish samples collected from Manzala Lake for heptachlor, aldrin, dieldrin, P,P9-DDE and malathion.…”

Pesticides constitute the major source of potential environmental hazard to man and animal as they are present and concentrated in the food chain. This study was conducted on 136 samples of water, sediment and fish for detection and determination of pesticide residues in this ecosystem. Highly significant differences were found in levels of Indian, heptachlor, endrin, dieldrin, P,P'-DDE and propoxur in River Nile water when compared with that of Manzala Lake. Levels of Indian, endrin, malathion and diazinon were significantly higher in soil sediment of Manzala Lake, while the levels of heptachlor, aldrine, P,P'-DDE, DDT, parathion, propoxur and zectran were significantly higher in soil sediment of River Nile. Boury fish of Manzala Lake contained higher levels of heptachlor, aldrin, P,P'-DDE and malathion, while boury fish of River Nile contained a higher level of zectran only. This survey, thus indicated that Manzala Lake and even the River Nile which was used as control are heavily contaminated with chlorinated hydrocarbons (Indian, heptachlor, aldrin, endrin, dieldrin, P,P'-DDE and DDT), organic phosphorus compounds (malathion, dimethoat, diazinon and parathion) and carbamate pesticides (propoxur and zectran).
