This study assesses the levels of heavy metals in vegetables (Cucumis sativus, Solanum lycopersicum, Ipomoea aquatica, Amaranthus cruentus, Basella alba, Brassica oleracea, Musa acuminata) collected from Kawran Bazar vegetable market located in Dhaka, Bangladesh. Also, it examines potential health risks from the consumption of these vegetables. The samples were randomly collected, processed and analyzed for heavy metals using Atomic Absorption Spectrophotometer. Among the vegetables Basella alba had the highest heavy metal content followed by Cucumis sativus, Amaranthus cruentus, Solanum lycopersicum, Brassica oleracea, Musa acuminate and Ipomoea aquatica. The average daily intake for Cr (0.245 mg/person/day) was above the permissible maximum tolerable daily intake of 0.20 mg/person/day endorsed by WHO/FAO (2013). The hazard quotient (HQ) values for Cd in Basella alba (4.400) and Brassica oleracea (1.333), for Cr in Ipomoea aquatica (1.756), Amaranthus cruentus (1.655), Basella alba (3.033) and Musa acuminate (1.333) as well as the hazard indices (HI) for I. aquatica (2.537), A. cruentus (2.791), B.alba (8.883), B. oleracea (2.295), M. acuminate (2.999) exceeded unity, signifying presence of health risks from consumption of the vegetables. This study recommends regular monitoring of heavy metals in vegetables and foodstuffs to prevent excessive accrual in food chain. Bangladesh J. Sci. Ind. Res.54(4), 357-366, 2019

El objetivo fue probar el efecto emiquecedor del jugo de hojas de rábano (Raphanus sativus) y de espinaca (Spinada oleracea), sobre un patrón de fennento de salvado de trigo (Triticwn aestivum) en la producción de Daphnia pulex. Los experimentos se llevaron a cabo en botellas de vidrio de 20 1 de capacidad, llenadas con agua del grifo desclorada a un volumen de 141. Los cultivos tuvieron una duración de 21 días, durante los cuales las botellas testigo tan solo recibieron fermento de salvado de trigo (Tríticum aestivum) y las botellas experimentales (I, JI Y III), en el primer caso recibieron la combinación de fermento y el jugo de hojas de rábano (Raphanus sativus), y en el segundo caso el fennento y el jugo de espinaca (Spinacia oleracea). La tasa de siembra en ambos experimentos fue de 200 organismos/ botella. Durante el desarrollo de los cultivos se evaluaron: temperatura del agua, oxígeno disuelto, pH. conductividad, alcalinidad y dureza total. Los parámetros ambientales se comportaron de manera similar en ambos experimentos. sin mostrar variaciones drásticas, ni grandes diferencias en sus registros. Las producciones netas obtenidas para la D. pulex fueron de: 1 722 organismos/botella en las testigo, 7 997 orglbotella en las de rábano (Raphamis sativus), y de 8 92 J org/botella en las de espinaca (SpiIlacia oleracea). De acuerdo con los datos de producción el análisis de varianza encontró diferencias significativas entre los cultivos (Fisher p< 0.(05) Y estableció que la combinación del fermento enriquecido con el jugo de espinaca (Spinada oleracea) esla mejor alternativa alimenticia para la Daphnia pulex en condiciones de laboratorio.

Water and soil samples were collected from five different industrial areas around Dhaka city namely, (i) Powertex Fashion Ltd., Gazipur (Textile), (ii) Shetu Pesticide Ltd., Savar (Pesticide), (iii) Salma Leather Industry, Hazaribagh (Tannery), (iv) Monno Ceramic Industries, Nayarhat, Dhamrai, (Ceramic) and (v) ACME Laboratories Ltd., Tulivita, Dhamrai (Pharmaceutical) where selected for this study. Two plants species viz. Colocasia esculenta (L.) Schott and Ipomoea aquatica Forssk. commonly growing in the industrial effluent affected areas were selected to observe the rate of heavy metal uptake. Dissolved oxygen (DO) was found below the permissible limit in all the affected areas (lowest 0.88 mg/l in tannery waste affected areas) indicating high amount of organic wastage discharge from tannery. Eight trace metals viz. arsenic, cadmium, nickel, iron, zinc, chromium, copper and lead were analysed for water, soil and plant samples. Arsenic and cadmium exceeded the permissible limit in water sample collected from all affected areas. Tannery waste affected area was found to be the most vulnerable area in respect to arsenic and chromium contamination. On the other hand, the highest amount of arsenic was found in the soil sample collected from pesticide affected area. The rate of heavy metal uptake in Colocasia esculenta (L.) Schott is much higher than Ipomoea aquatica Forssk. More heavy metals were accumulated in edible portion than roots of the plants.

Lutein Content

Green leafy vegetables (GLV) are rich sources of micronutrients, which have many health benefits and have the potential to combat the problem of malnutrition. However, domestic processing and cooking alter the nutrient contents. To study the retention of xanthophylls after processing, ten different GLV which are commonly available and regularly consumed, were analysed for total carotenoids, lutein, zeaxanthin and violaxanthin in both raw and cooked forms. In the unprocessed GLV, the lutein content on dry basis ranged from 341 mg/kg in Murraya koenigii to 959 mg/kg in Spinacia oleracea while zeaxanthin ranged from traces in Coriandrum sativum and Rumex acetosa to 15.45 mg/kg in Basella alba. In the case of violaxanthin, while it was not detectable in Hibiscus cannabinus, Amaranthus viridis had 794 mg/kg. The total carotenoids, lutein, zeaxanthin and violaxanthin in the processed GLV varied based on the variety of leafy vegetable cooked and the method of cooking. Microwave cooking followed by steaming were the most recommended method, while deep frying drastically reduced the total carotenoids and xanthophyll content followed by sautéing with oil. Overall, different methods of cooking resulted in changes in the phytochemical composition which are due to various factors such as leaf matrix, cooking method, cooking time and temperature.
