“…Since invasive species are highly competitive, they interact with native species (e.g. predation, competition and hybridization) causing serious biodiversity loss even sometimes the extinction of native species; trophic alterations; health hazards, and economic damage affecting the ecosystem services (Sarkar et al, 2012;Singh et al, 2013a;Singh et al, 2012Singh et al, , 2014. Invasive non-native species in inland waters have been associated with altered trophic structure adversely affecting habitat for native species.…”

India, a megadiverse tropical country is grappling with the rising trend of aquatic invasions. Out of 532 introduced non-native fish, 16 species of freshwater aquaculture and aquarium were assessed invasive by using a risk assessment protocol, ‘Fish Invasiveness Screening Test’. Six major identified invasion pathways of the aquatic invasive species were inadvertent or deliberate releases, escapes, contaminants from hatcheries, river corridors, stowaways and unaided introductions. Invasion mechanism further elucidated the factors promoting successful invasion in freshwater ecosystems. For predictive future performance of invasive fish, the concrete and predictive values based on mean abundance by weight was calculated. Over 28.67% and 29.02 % persistent increased yield of the invasive Tilapia and Common Carp respectively was predicted in the Ganga river in the coming decades. Single species Tilapia invasion facilitated multiple species fish invasion, manifesting in invasion meltdown. The trophic changes due to fish invasion exhibited biotic homogenization with trophic downgrading. Aquatic invasive species were found highly competitive interacting with native species causing serious biodiversity loss, health hazards, and economic damage consequently affecting the ecosystem services. In spite of available regulatory approaches and guidelines to manage aquatic invasive species, fish invasion has been on the rise. This paper suggests modifications and stringent implementation of the existing regulatory mechanisms besides adopting linkages, cutting-edge research on invasion science and modern molecular containment tools for effective management.

Determination of Heavy Metals in Water and Tissues of Crucian Carp (Carassius auratus Gibelio) Collected from Subsidence Pools in Huainan Coal Fields (China)

Heavy metals are an important class of chemical contaminants and food is a major vehicle for entry into the ecosystem. Crucian carp (Carassius auratus Gibelio) is an aquatic organism affected by metals and constitutes a major source of contaminated food in the subsidence area. Therefore, cadmium, copper, lead, and zinc were determined in the water of subsidence pools and different tissues of Carassius auratus Gibelio. In addition, the metal concentrations in water and fish from this study were compared with national and international quality guidelines and literature values. The concentrations of metals in water were in the range of 4.05 to 15.49 µg L -1 for zinc, 3.03 to 5.43 µg L -1 for lead, 0.33 to 1.48 µg L -1 for cadmium, and 7.25 to 26.93 µg L -1 for copper, which are within the permissible levels for culturing fish. Metal concentrations in tissues (viscera, gills, and muscle) varied significantly depending on the site. In Carassius auratus Gibelio, the accumulation of metals was in the sequence viscera > gills > muscle. Metal Downloaded by [Universite Laval] at 17:39 27 December 2014 2 concentrations in muscle (Zn, 8.63 to 10.5 mg kg -1 ; Pb, 0.12 to 0.36 mg kg -1 ; Cd, 0.005 to 0.01 mg kg -1 ; Cu, 1.14 to 1.77 mg kg -1 ) of Carassius auratus Gibelio were far below the permissible limits proposed by Food and Agriculture Organization/World Health Organization and Chinese legislation, suggesting that the fish were safe for human consumption. Correlations between metal concentrations in tissues of Carassius auratus Gibelio and in water are reported.

“…The safe level of As in drinking water as recommended by the WHO is 10 µg/L mostly followed all over the world except some Southeast and South Asian countries [19]. Given the WHO recommendations for As in groundwater, about 200 million people all over the world are at the threat of As contamination and 100 million people are facing As-induced risk in Southeast and South Asia [20,21]. The purpose of this research was to evaluate the potential hazards of Cd and As in groundwater of two Talukas of district Thatta namely Ghorabari and Mirpur Sakro, using Flame Atomic Absorption Spectrometer (FAAS) and Arsenic Kit Method to measure the health risks associated with Cd and As contamination.…”

The current study was carried out for quantitative and risk assessment of cadmium (Cd) and arsenic (As) from Talukas Ghora Bari and Mirpur Sakro. The concentration of Cd was determined using Atomic Absorption Spectroscopy instrument. The As concentration was measured with the help of the Arsenic Kit Method. For analysis of Cd, samples were prepared by the Microwave digestion method, whereas for As analysis, water samples were analyzed directly. The range of Cd content was observed from the studied areas as 1 – 10 μg/L and 1.2 – 11.2 μg/L, respectively. The groundwater water of Talukas Ghorabari and Mirpur Sakro showed the mean Cd content of 5 μg/L and 6.1 μg/L, respectively. The Cd contamination of 56% and 80% was found in Ghorabari and Mirpur Sakro, respectively. The range of As content of 0.00 – 50 μg/L and 10 – 80 μg/L was determined from Ghorabari and Mirpur Sakro, respectively. Hazard Quotient for Cd > 1 was found in 40% of both children and infants in the groundwater of the study area, which may cause non-carcinogenic risk. About 48% of water samples declared HQ values > 1 for adults in the water of Ghorabari. Since 84% of samples showed the HQ values > 1 for children and infants. The HQ values of As for Adults of the Mirpur Sakro were observed in 63.3% samples, whereas for children and infants, HQ values were found in 100% samples. It is therefore strongly recommended that groundwater must be treated before consumption by the people of the area under study.
