“…Another study reported by Radwan and Salama [36] in Egypt shown a value of 0.01 ppm for total Pb. By contrast, the results found are lower than those found by Parveen et al [37] in Pakistan with values of 1.33 ppm for total Cd and 1.56 ppm for total Pb; Kananke et al [38] with values from 0.18 to 1.59 for total Pb and Al-Chaarani et al [39] in Tripoli (Lebanon) with values of 0.17 to 0.82 ppm for total Cd. Trace metals found in tomato samples may originated from environment as soil, water dams, dwells and air [40] and also due to the agricultural activity such as the use of chemical fertilizers, pesticides and household waste [41].…”

Tomato (Lycopersicon esculentum Mill) is quantitatively the highest vegetable consumed in Burkina Faso. The objective of this study was to evaluate the physico-chemical, nutritional characteristics, and sanitary quality of the tomato variety Mongal F1 from different production sites. Twenty-eight (28) samples of Mongal F1 fresh tomatoes were collected from 28 producers at three different localities of Ouahigouya, Loumbila and Ouagadougou. The physico-chemical and nutritional characteristics were determined by standardized methods and the traces metallic elements by atomic absorption spectrophotometry. The results revealed a degree brix varying from 4.07˚ to 5.50˚ and a pH ranging from 3.71 to 4.08 corresponding to a total acidity of 0.39% to 0.55% citric acid equivalents. The moisture content, the ash content, the total carbohydrates content, the reducing carbohydrates content, the lipids content and the protein content were ranged from 95.09% to 96.17%, 9.25% to 10.60%, 47.00% to 53.43%, 30.03% to 41.21%, 3.04% to 7.71% and 17.09% to 25.03% respectively. The results of the trace metals showed a high accumulation of total cadmium from 0.11 to 0.22 ppm, of total lead of 1.15 to 1.27 ppm and arsenic total of 0.19 to 0.20 ppm. The results proved that environmental conditions influence the quality of the tomato Mongal F1. Detection of trace elements in the tomato fruits suggests that a better production practices are needed.

Elemental Profile of Heavy Metals in Garden cress, Coriander, Lettuce and Spinach, Commonly Cultivated in Kahrizak, South of Tehran- Iran

Heavy metal accumulation in vegetable tissues often poses a great risk for human health. In the present study, accumulation of heavy metal in green leafy vegetable crops of coriander, garden cress, lettuce and spinach were evaluated under waste water irrigation in fields located in Kahrizak, on the southern edge of the metropolitan city of Tehran, Iran. Atomic absorption spectrophotometery was used for determination of heavy metal concentrations in leaf tissue. The results showed that heavy metal concentrations in soil and irrigation water were significantly high than allowable levels. Analysis of plant leaf tissue showed that spinach and garden cress accumulated higher concentrations of heavy metals compared to coriander and lettuce plants. Central leaves of lettuce showed the lowest heavy metal concentration compared to outer leaves or leaves of other vegetable crops, and can be the safer product for fresh consumption. The results indicate that the vegetables produced in the region are not suitable for fresh consumption and the agricultural activities should change towards ornamental or industrial crops production.

“…All these factors can happen to the studied specimen. Both water and sediments in Sri Lanka were shown to be highly polluted with different types of pollutants (Vidanaarachchi et al, 2006;Bandara and Hettiaratchi, 2010;Seneviratne, 2011;Kananke et al, 2014).…”

Cases of lordosis including one flexion is described in one specimen of Puntius kamalika. To estimate the severances of lordosis several morphometric measurements of the vertebrae were taken in addition to the angle found in between the two sides of the lordotic vertebrae. The depth of the curvature is also measured to estimate the severity of the case. Causes of these cases were of anomalies were discussed.
