“…Iron is present in small quantities in all types of samples compared to other macronutrient and lowest concentration is found in Brinjal. Lokeshappa et al (2012) studied the elemental concentration in different agricultural product and the results obtained are comparable with the present study. Among the micronutrient Cu and Zn is abundant in all varieties and concentration of zinc is high comparable to copper.…”

“…Vegetables act as buffering agents for acid generation during digestion (Maleki and Zarasvand 2008) and some metals present in vegetables are even important biochemically and psychologically from health point of view. Metals like cobalt (Co), chromium (III) (Cr), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se) and zinc (Zn) help in regulating human metabolism (Lokeshappa et al 2012). Manganese is an essential elements act as an activator and constituent of many enzymes present in human (Sresty and Rao 1999).…”

Transfer of metals from soil to vegetables and possible health risk assessment

Metal contamination in agricultural soils is of increasing concern due to food safety issues and potential health risks. Accumulation of Heavy and trace metals in vegetables occur by various sources but soil is considered the major one. Consumption of vegetables containing (heavy/trace) metals is one of the main ways in which these elements enter the human body. Once entered, heavy metals are deposited in bone and fat tissues, overlapping noble minerals and cause an array of diseases. The present study aimed to investigate the concentration of different metals in agricultural soil and vegetables grown on those soils and to evaluate the possible health risks to human body through food chain transfer. Contamination levels in soils and vegetables with metals were measured and transfer factors (TF) from soil to vegetables and its health risk were calculated accordingly. Results showed that concentration of Si, Ba, K, Ca, Mg Fe, Sc, V, Cr, Cu, Zn, As, Mn, Co, Ni, Se, Sr, Mo, and Cd in soil is higher than the World Average value and Al, Ti and Pb is lower than the World Average value whereas concentration of toxic elements like As, Co, Cu, Mn, Pb, Se, Ni, V and Zn in vegetable samples are below the World Average value. The intake of toxic metals (Fe, Cu, Mn, Zn Co, Cr, V, Ni, Pb and Cd) from vegetables is not high and within the permissible limit recommended by WHO, Food & Nutritional Board and US EPA. The Hazard Quotient (HQ) for Fe, Cu, Co, Cr, V, Ni, Pb, Mn, Zn and Cd were calculated which showed a decreasing order of Cd>Mn>Zn>Pb>Cu>Fe>Ni>V=Co>Cr. Highest HQ value found for Cd (2.543) which is above the safe value.Electronic supplementary materialThe online version of this article (doi:10.1186/2193-1801-2-385) contains supplementary material, which is available to authorized users.

“…Macronutrients (K, Ca and Na) are abundant in all type of vegetables. Lokeshappa et al studied the elemental quantity in different agricultural products and the results obtained are comparable with the present study (Lokeshappa et al, 2012). Since, there was no industrial unit near the study area, so the presence of Ni, Cd and Pb in smaller quantity indicates that they may have been come from atmospheric deposition by air or other anthropogenic sources.…”

Field experiment was conducted in absence and presence of potash and gypsum fertilizers, to compare and investigate the quantity levels of heavy metals and nutrients in leafy vegetables with growth stage and plant species variations, respectively. Seeds of Spinacia oleracia (Spinach), Colocasia esculenta (Taro), Ipoma aquatica (Water spinach), Cucurbita maxima (Pumpkin leaves), Basella alba (Indian spinach), Amaranthus gangeticus (Red amaranth), Coccinia grandis (Ivy gourd), Corchorus olitorius (Jute leaves), Basella rubra (Malabar Spinach), Coriandum sativum (Coriander leaves), Amaranthus lividus (Amaranth) were sown in the experimental filed in Joypurhat district of Bangladesh. The quantity of heavy metals [cadmium (Cd), lead (Pb), nickel (Ni), and zinc (Zn)] and nutrients [sodium (Na), potassium (K) and calcium (Ca)] in vegetables were determined by atomic absorption spectrometer and flame photometer, after the microwave digestion of these vegetables with 70% concentrated HNO3. The quantities of heavy metals were increased with the age of the plant, but the increases were not linear. Moreover, the order of heavy metals level in different vegetables was Zn >Ni >Cd >Pb. The Hazard Quotient (HQ) for Zn, Ni, Cd and Pb were as 0.143, 0.085, 0.1029 and 0.806, respectively. The sequence of HQ for the heavy metals followed the decreasing order Pb >Zn >Cd >Ni. The HQ value for all the heavy metals, Zn, Cd Ni and Pb were less than 1, which is considered safe or indicates no adverse effect on human health.

“…In the case of plants, symptoms of toxic action may be inhibition of photosynthesis, decreased yield and dieback (Zn, Cu and Pb), dysfunctional root development and DNA damage (Cu and Pb) and impaired water economy (Pb) (Kabata-Pendias and Mukherjee 2007; Wilk and Gworek 2009). The effects of high doses of analysed metals on animals and humans can cause gastrointestinal disorders, osteoporosis, lymph node dysfunction (Zn), dysfunction of DNA and certain enzymes, cell damage, allergies, hypertension, diabetes, depression (Cu and Pb), nervous system damage, renal failure, anaemia, cancers, infertility, decreased immunity and anorexia (Pb) (Lokeshappa et al 2012; Seńczuk 2002). …”

Several years of observations enabled us to assess the extent and variability of heavy metal contamination (Zn, Cu and Pb) of the sludge of the municipal stormwater treatment plant (the town of Puławy, Poland). In terms of size (high capacity) and innovation, it is the only facility of this kind in the country. It collects rainwater run-offs from two catchments (separate inlets) with a total area of about 500 ha. The concentration of the analysed metals is characterised by a large spatial and temporal diversity. The reason for this may be differences in the manner and intensity of use of drained surfaces and different hydraulic conditions (of sedimentation) prevailing in the particular treatment devices. The highest pollution was found in sediments in the grit chamber and in the part of the settler from the side of the interceptor supplying sewage, i.e. from the main traffic route of the town (heavy traffic and developed technical infrastructure). The best-quality sludge was retained in the pond for treated wastewater. In the pool of analysed components, the largest share is Zn, which amounts to about 85%. The content of heavy metals limits the possibility of the natural use of sludge from the municipal stormwater treatment plant. In chemical terms, they should be seen as a potentially dangerous waste and undergo remediation.
