    ABSTRACT: Graphene oxide (GO) nanosheets have been extensively investigated to fabricate the graphene in recent years. The migration of GO nanosheets into the environment could lead to the instability of biological system. In this study, the GO nanosheets were synthesized and were characterized by SEM, high resolution TEM, XRD, Raman, FTIR and XPS techniques. Toxicology testing of GO nanosheets against Paecilomyces catenlannulatus (P. catenlannulatus) was performed by measuring the efflux of cytoplasmic materials of P. catenlannulatus. Approximate 35 % of the bacteria could survive on the surface of GO nanosheets compared to the control sample (~92 %) within 3 h, indicating that GO nanosheets presented significantly antibacterial activities. It was observed that the concentration of RNA in the solution was obviously higher than that of control sample, which could be due to direct contact of the bacterial cell. The results showed that the damage of cell membrane of P. catenlannulatus was attributed to the direct contact of the P. catenlannulatus with the extremely sharp edges of GO nanosheets, which resulted in the P. catenlannulatus inactivation. The less resistant to the damage of cell membrane was observed with increasing of GO concentration and contact time.

    ABSTRACT: In this paper, the joint effect of 0.5 mmol·L(-1) Cd(2+) and various concentrations (50-400 mg·L(-1)) of the ionic liquid 1-butyl-3-methyl-imidazolium acetate ([C4min][OAc]) on the growth and photosynthetic performance of wheat seedlings in hydroponic culture was investigated. Seedlings grown in presence of Cd(2+) and [C4min][OAc] showed significant (p < 0.05) improvement in growth (shoot and root lengths and dry weights) and photosynthetic performance (photosynthetic rate, stomatal conductance, transpiration rate, and chlorophyll a but not chlorophyll b) compared to seedlings grown in the presence of Cd(2+) but without [C4min][OAc]. However, this only happened under the lower range of [C4min][OAc] concentrations (50-200 mg·L(-1)). In addition, significant reduction in the level of Cd(2+) was also observed in the leaf tissue of wheat seedlings grown in the presence of 0.5 mmol·L(-1) Cd(2+) and 100 mg·L(-1) [C4min][OAc]. Overall, Cd(2+) exerted a stronger inhibition than [C4min][OAc] on the growth and photosynthetic performance of wheat seedlings. However, when both Cd(2+) and [C4min][OAc] were present in the culture, the toxicity of Cd(2+) could be mitigated by lower concentrations of [C4mim][OAc]. This phenomenon could be due to [C4mim][OAc] forming metal complexes with Cd(2+), thus reducing the toxicity of Cd(2+).

    ABSTRACT: In the present study, the current levels of pesticide residues were studied in the human populace of Punjab state. A total of 111 human blood samples were analyzed by gas chromatography and pesticide residues were detected in 35 % of the blood sample(s). Residues of alpha-hexachlorocyclohexane (α-HCH), beta-hexachlorocyclohexane (β-HCH), p,p'-dichlorodiphenyldichloroethane (p,p' DDD), p,p' dichlorodiphenyldichloroethylene (p,p' DDE), p,p' dichlorodiphenyldichloroethane (p,p' DDT), β-endosulfan, monocrotophos, profenophos and phosalone were found in human blood samples with mean levels of 1.11, 5.89, 0.51, 3.88, 0.39, 34.90, 0.79, 0.39 and 6.76 ng ml(-1), respectively, with β-endosulfan as a leading pesticide residue. A paradigm shift in the pattern of the pesticide usage was observed with a shift from organochlorine pesticides to organophosphates.

    ABSTRACT: Effects of rice husk gasification residues (RHGR) application on the fate of herbicides, butachlor and pyrazosulfuron-ethyl, in paddy water were investigated using micro paddy lysimeters (MPLs). The dissipation of both herbicides in paddy water was faster in the RHGR treated MPL than in the control MPL. The average concentrations of butachlor and pyrazosulfuron-ethyl in paddy water in the lysimeter treated with RHGR during 21 days were significantly reduced by 51 % and 48 %, respectively, as compared to those in the lysimeter without RHGR application. The half-lives (DT50) of butachlor in paddy water for control and treatment were 3.1 and 2.3 days respectively, and these values of pyrazosulfuron-ethyl were 3.0 and 2.2 days, respectively. Based on this study, RHGR application in rice paddy environment is an alternative method to reduce the concentration of herbicide in paddy field water and consequently to reduce potential pollution to aquatic environment.

    ABSTRACT: To determine the actual concentrations of trace elements in surface sediments from the La Paz Lagoon, as well as their associations and possible origins, 91 sediment samples were analyzed for more than 50 elements using a combination of ICP-MS and ICP-AES. The results of a principal component analysis are used to distinguish four associative groups within the elements. Natural enrichment of As, Cd and U occurs due to the supply of weathered phosphorites from the El Cien formation located to the north-west of the lagoon. Sediment quality indices for potentially toxic trace elements do not show any probable impact on the biota of the lagoon. Only the concentrations of As in 30 % of the stations and Cu in 20 % of them exceed related effect range low levels. The highest concentration of Pb (36.8 mg kg(-1)) was measured in the sediments near the City of La Paz.

    ABSTRACT: The present study is an attempt to assess the pollution intensity and corresponding ecological risk of heavy metals such as Cd, Ni, Pb, Cu, Zn and Cr using various indices like geo-accumulation index, concentration factor, pollution loading and ecological risk index. In all 21 surface sediments samples were collected from the stream flowing around the solid waste disposal landfill of Qayen city in southeastern Iran. Although Igeo values for Cd varied greatly, sites 18-21 with class 5 show heavy loads of Cd (values between 4.13 and 4.45). PLI values (3.37-12.89) clearly suggest strong contamination with respect to the measured metals. This study clearly indicates that the contamination risk in the downstream reservoir is much higher than upstream sites due to transfer and accumulation of leached metals from upstream to downstream.

    ABSTRACT: In the frame of a long-standing action of remediation of industrial soil and prevention of water pollution, a monitoring of the drinking water of the Italian town of Colleferro was performed by the ISS. The town has 22,000 inhabitants and is adjacent to a big industrial site where HCH was produced. Industrial wastes were buried in the site, eventually contaminating superficial aquifers, while a canal serving the industrial plant spread the contamination into the Sacco river and thence to the agricultural soil and to cow milk. The contamination of superficial aquifers engendered fears of pollution of the deep aquifers whence the town draws its drinking water. The results of the monitoring indicate that there is no risk for the population from consumption of the water. In one of the wells the ε-HCH was the main isomer reaching a concentration of 66 ng/L: so far the presence of this isomer in water was never reported. The paper also summarily reports the main features of soil and superficial groundwater pollution in the area and briefly describes the main actions taken by the authorities.

    ABSTRACT: Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in ambient air and farmland soil sampled in 2006 around an e-waste dismantling area with open burning of insulated wires in Longtang in south China were investigated. The total toxic equivalent concentrations of PCDD/Fs were 3.2-31.7 pg/m(3) in air and 5.8 12.4 ng/kg in farmland soil at an e-waste site and 0.063-0.091 pg/m(3) in air at a background site. PCDD/Fs in the air at the e-waste site were characterized with dominant 1,2,3,4,6,7,8-HpCDF and OCDF and higher concentrations of furans than dioxins, suggesting open burning of insulated wires was likely to be the main source of PCDD/Fs. Compared with the results in this study, the level of PCDD/F tended to lessen with the average TEQ concentration decreasing by 41 % and the pattern changed to be dominated by OCDD in the air of Longtang in 2010 when insulated wires were openly burned in only a small scale. Our results indicate that the lower chlorinated congeners with higher vapor pressures have enhanced atmospheric transport tendencies.

    ABSTRACT: In order to be a relevant indicator of exposure towards teratogenic stressors, morphological defects should not be passed on to the next generation. In this study, we compare morphological variations in Chironomids collected from a contaminated river stretch with those of their progeny, reared in uncontaminated sediment under laboratory conditions. We focused on mentum defects (deformities, fluctuating asymmetry and mean shape change), measured by geometric morphometrics. We observed no significant variation in deformity rate between the parental generation and its progeny. On the contrary, we observed a significant increase in fluctuating asymmetry and a significant decrease in mentum centroid size in the offspring. Our results suggest that shape defects are not caused by direct exposure to teratogenic stressors alone. We propose four hypotheses to explain this: (a) teratogenic contaminants are present in egg-clutches, (b) contaminants at the sampling site have mutagenic effects, (c) costs of tolerance, and (d) contamination-induced genetic impoverishment.

    ABSTRACT: Groundwater contamination characteristics and the potential fate of chlorohydrocarbons were investigated at a combined polluted groundwater site in North China. Groundwater chemistry and (2)D and (18)O isotope compositions indicated that high salination of groundwater was related with chemical pollution. The elevated salinity plume was consistent with the domain where typical chlorohydrocarbon contaminants occurred. The concentrations of heavy metals, oxidation-reduction potential, and pH in organic polluted areas significantly differed from those in peripheral (background) areas, indicating modified hydrochemistry possibly resulting from organic pollution. Under the presented redox conditions of groundwater, monochlorobenzene oxidation may have occurred when the trichlorohydrocarbons underwent reductive dechlorination. These findings suggested that inorganic hydrochemistry effectively indicated the occurrence of chemical contamination in groundwater and the potential fate of chlorohydrocarbons.

    ABSTRACT: We investigated whether the proximity to the Gabès-Ghannouche factory complex of phosphate treatment, in south-eastern Tunisia, was associated with notable changes in the condition and health of Rufous bush robin (Cercotrichas galactotes) nestlings hatched in the neighbouring oasis habitat. Results demonstrated that excrements of nestlings hatched in one oasis close to the factory complex contained higher concentrations of lead and zinc than the excrements of nestlings from one oasis situated 20 km away. Furthermore, when effects of age and nestling number in the nest were controlled, nestlings hatched near the factory complex showed reduced tarsus length, rectrix length, haematocrit level and haemoglobin concentration, but higher levels of fluctuating asymmetry compared to those from the more distant oasis. Overall, results suggest that the proximity to the factory complex was associated with increased exposure to metals and deterioration in nestling condition and development.

    ABSTRACT: The growing use of nanoparticles in a wide range of products has resulted in their release into the aquatic environment; therefore, an understanding of the toxic effects of nanoparticles on aquatic organisms is of permanent importance. The aim of this study was to evaluate the toxicity of silver and platinum nanoparticles toward the freshwater microalga, Pseudokirchneriella subcapitata. Algal growth and photosynthetic pigments were determined to quantitate the effects of varying concentrations of Ag and Pt nanoparticles. The silver nanoparticles were much more toxic than the platinum ones. The concentrations causing total inhibition of algal growth were 5.0 and 22.2 mg L(-1), respectively. Similar results were obtained by analyzing the concentration of photosynthetic pigments in P. subcapitata exposed to nanoparticles. Thus, simple spectrophotometric determination of chlorophyll is a convenient tool for the analysis of nanoparticle toxicity to algae.

    ABSTRACT: In this study, we evaluated the accumulation and metabolism of four metalloids: arsenic (As), selenium (Se), antimony (Sb), and tellurium (Te) in garlic to determine whether garlic can be used for the phytoremediation of those metalloids. Garlic was able to efficiently accumulate As and Se, the two-fourth-period metalloids. However, it was not able to accumulate Sb and Te, the two-fifth-period metalloids, because their bioaccumulation factors were below one. Speciation analyses revealed that four metalloids could be metabolized in garlic, although their metabolites could not be identified yet. Results also suggested that garlic was able to distinguish the metalloids in groups 15 and 16 and the fourth and fifth periods, i.e., As, Se, Sb, and Te. Therefore, garlic is one of the potential plants for the phytoremediation of the fourth-period metalloids.

    ABSTRACT: In order to examine the effects of crude oil and dispersed crude oil (DCO) on the swimming ability of puffer fish, Takifugu rubripes, the critical swimming speeds (U crit) of fish exposed to different concentrations of water-soluble fraction (WSF) of crude oil and DCO solution were determined in a swimming flume. WSF and DCO significantly affected the U crit of puffer fish (p < 0.05). The U crit of puffer fish exposed to 136 mg L(-1) WSF and 56.4 mg L(-1) DCO decreased 48.7 % and 43.4 %, respectively. DCO was more toxic to puffer fish than WSF. These results suggested that crude oil and chemically dispersed oil could weaken the swimming ability of puffer fish.

    ABSTRACT: Two sites of collection along river Nile, nearby metal-related factories (site2) and 7 km downstream (site3) were compared to unpolluted reference fish farm (site1). Metals concentration (Cu, Zn, Pb, Fe, Mn and Cd) in water and sediment samples showed highly significant (p < 0.01) differences among sites. According to contamination factor and pollution load index values, overall pollution was ordered as site2 > site3 > site1. Compared with Oreochromis niloticus of site1, activities of superoxide dismutase, catalase and glutathione-S-transferase as well as malondialdehyde formation were significantly (p < 0.01) increased in both liver and gills of fish collected from metal contaminated sites. This increment showed a tissue-specific pattern with higher rate of increment in liver than in gills. While reduced glutathione level was sharply decreased in site2 and site3. Micronucleus test was assessed as an environmental genotoxic endpoint in erythrocytes. Assessment of eight nuclear deformations showed gradient frequencies related to the distance from the industrial discharges.

    ABSTRACT: Changes in the blood parameters of fingerlings of Clarias gariepinus were investigated after 24 and 96-h of exposures to endosulfan. 180 fingerlings of C. gariepinus [mean weight (10.5 ± 1.3 g); total length (11.2 ± 1.2 cm)] were exposed to five different concentrations (1.00, 2.20, 4.80, 11.00, 23.00 µg/L) of endosulfan and a control for 96 h after being acclimatized for 21 days. After 24 h of exposure, microcytic hypochromic anemia was observed and all erythrocyte profiles tested showed significant variation (p < 0.05) among the treatments except thrombocyte and mean corpuscular hemoglobin concentration. Macrocytic hyperchromic anemia was noticed after 96 h of exposure and all the hematological parameters varied significantly (p < 0.05) except packed cell volume and red blood cell count. The study shows that endosulfan alters the hematology of C. gariepinus fingerlings. Therefore, awareness on the hazards associated with the use of endosulfan should be intensified and sound sustainable alternatives to endosulfan should be developed.

    ABSTRACT: Quinazoline derivatives have wide biological activities and therapeutic properties, implying their potential for development and application on a large scale. In the present study, 2-(4-chlorophenyl)-4-(4-methoxyphenyl) quinazoline (CMQ), was selected to examine its effect on unicellular cyanobacteria, Microcystis aeruginosa by evaluating growth, physiological and molecular responses. Growth was inhibited by CMQ, with a 96 h EC50 of 1.93 ± 0.19 mg L(-1). The up-regulated expression of prx was shown, reflecting that oxidative stress might be a toxic factor of CMQ. At higher concentrations of CMQ, the quantum yields of Y(II) and Y(NPQ) in photosystem II decreased seriously and Y(NO) increased sharply, and psbA gene encoding for D1 protein was over-expressed. These results demonstrated that high concentrations of CMQ had different inhibitory targets associated with photosystem electron transport and with sites beyond the electron transport chain, leading to severe toxicity.
