“…In Monhystera microphthalma we found a 4-fold reduction of LC 50 by extending the exposure time from 96 h to 312 h. In M. disjuncta and Pellioditis manna, 96 h LC 50 values were not determinable; in the first-named species LC 50 values were reduced from 28 pprn at 144 h to 18.4 pprn at 264 h. A similar time-dependency of LC 50 has been reported in the literature. For the nematode Panagrellus silusiae Cd LC 50 was reduced from 111 pprn after 24 h, to 13.2 pprn for an exposure time of 72 h ; LC 50 for the grass shrimp Palaemonetes vulgaris was reduced from 760 ppb to 120 ppb Cd by extending the exposure time from 96 h to 29 d (Nimmo et al 1977), and Best & Morita (1983) reported that for the asexual planarian Dugesia dorotocephala the 5 d LC 50 was in the 2 to 3 pprn range; the 12 d LC 50, less than 0.4 pprn Cd.…”

“…Ahsanullah et al (1981) suggest that even a period of 14 d is insufficient for completing meaningful acute lethal tests of cadmium, zinc and copper on the marine shrimp Callianassa australiensis. Nimmo et al (1977) report for pink shrimp Penaeus duorarum a decrease in Tisbe holothuriae. These values show that median lethal threshold concentrations for some metals are time-dependent.…”

Cadmium toxicity to 3 marine and brackish-water nematodes (Monhystera microphthalma, M. disjuncta, Pellioditis marina) was estimated under static tests. These nematodes are very resistant to cadmium poisoning. LC 50 values are extremely time-dependent; an exposure time of 96 h underestimates the degree of toxicity. For M. rnicrophthalrna LC 50 values decreased from 23.6 ppm after 96 h to 5.4 ppm after 312 h. For M. disjuncta LC 50 values were 21.2 and 18.4 ppm after 192 and 264 h respectively. P. marina was much more tolerant to cadmium in comparison with the monhysterids and had LC 50 values of 90.5 ppm at 120, and of 77.0 ppm at 192 h. It is argued that MEC (minimum effective concentrations) values are ecologically more meaningful than LC 50 values, and that the former levels can be used as indicators of intolerable thresholds in the field. MEC values based on mortality and on a developmental assay in which success in attaining the adult stage was studied, turned out to be very similar. The developmental assay takes less time than the survival assays and the slope of the response curve can be used as a parameter for describing species sensitivity.

“…The blackening of carapace and post abdominal claw due to exposure of toxicant were very pronounced in the present investigation (Plates 1 and 2). The gill blackening has been reported in P. duroronum, Palaemonetes pugio, P. vulgaris after cadmium chloride exposure (Nimmo et al, 1977 andVerma et al, 2010); in Caridina rajdhari after CuSO 4 .H 2 O exposure (Ghate and Mulherker, 1979), in P. pugio after hexavalent chromium exposure ( Doughtie et al, 1983). in C. rajdhari and M. kistenensis after mercury and cadmium exposure (Ghate, 1984).…”

“…in C. rajdhari and M. kistenensis after mercury and cadmium exposure (Ghate, 1984). The probable reason for blackening may be due to cell necrosis in the gill tissue (Nimmo et al,1977), while Ghate, (1984) opined that deposition of melanin caused blackening of the gills. Heavy metals influence a broad spectrum of physiological processes in organisms particularly the nervous system.…”

Water fleas constitute major zooplankton population of fresh water aquatic ecosystem. Their population density is an indicative of well-being of aquatic bodies. Simocephalus vetulus (Crustacea -Cladocera) is a tailless water flea and is well suited lab model for environmental monitoring. Copper a Gray listed heavy metals despite being an essential micronutrient, becomes highly toxic when present in excess quantity in aquatic ecosystem thereby causing deleterious effects on aquatic flora as well as fauna. The water-flea exposed to acute 0.37 mg/l (96hr LC 50 ), sub-acute 0.0925 mg/l (25% of 96hr LC 50 ) value and chronic 0.037 mg/l (10% of 96hr LC 50 ) value of copper sulphate and acute 0.16 mg/l (96 hr LC 50 ), sub-acute 0.04 mg/l (25% of 96 hr LC 50 ) value and chronic 0.016 mg/l (10% of 96 hr LC 50 ) value of potassium chromate showed behavioural alterations like initial hyperactivity, fast appendage movements and in phototaxis, geotaxis and avoidance indices. At later stage erratic swimming and spinning, reduced activity, loss of balance, reduced feeding and darkening of cuticular coloration, reduced phototactic, geotaxis and avoidance indices were the major effects on its behaviour. The behavioural alterations of S. vetulus showed the most susceptible and foremost indication of potential toxic effects. Various behavioural parameters, used in present study may serve as better biomarkers about metal toxicity and monitoring of drinking water quality.

“…Nimmo et al (1977) studied the effects of cadmium in the shrimp Penaeus duorarum Bukenroad, Palaemonetes pugio Holthius Present address: National Center for Marine Research, Agios Kosmas, GR-166 04 Hellinikon. Athens, Greece and Palaemon vulgaris L. They found significant accumulation of cadmium by the hepatopancreas of controls after 96 h. The rate of uptake in the hepatopancreas was considerably higher than in the gills in the 3 species, and these values for both tissues increased in relation to the concentration.…”

Accumulation of cadmium in the hepatopancreas of the common prawn Palaemon serratus (Pennant) and ultrastructural changes m hepatopancreatic cells were examined after exposure to 3 cadmium concentrations (5, 25.50 ppm) for 44 h. Accumulation of cadmium Ions in 50 ppm solution was 800 % higher compared with control specimens. Absorptive and fibrillar cells (R-and F-cells) in the hepatopancreas were affected by cadmium ions at the ultrastructural 1evel.The ultrastructural changes observed suggest impairment of ion transport, absorption and proteln synthesis.
