“…Seeds in polluted plants had a higher Cd concentration than those in non-polluted plants, but the mean value (239 mg kg ) was still below the y1 toxicity level for livestock (500 mg kg , Chaney, y1 1989) and the threshold recommended for human nutrition (1000 mg kg , Hapke, 1996). Seeds y1 collected from the directly flooded plants in 1998 (1st scenario) had a similar Cd concentration (mean of 241 mg kg , Murillo et al, 1999).…”

The failure of a tailing pond dam at the Aznalcóllar pyrite mine (SW Spain) in April 1998 released a toxic spill affecting approximately 4300 ha along the Agrio and Guadiamar valleys. Two years later, we have studied yield and concentration of mineral nutrients and trace elements in sunflower plants grown in the spill-affected soil, and in an adjacent unaffected soil as comparison. The study has been carried out in plants at seedling (V4) and mature (R8) stages. Shoot and root biomass of sunflower seedlings was significantly smaller in the affected soil than in the unaffected soil, but there was no significant difference at the mature stage. Oil production was greater in the spill-affected plants. We have not detected any 'fertilising' effect caused by the acid waters of the spill on the main nutrient (N, P and Ca) acquisition, as documented in 1998 for sunflower plants flooded by the spill. Sunflower plants growing in the spill-affected soil reached adequate levels of nutrients. None of the trace elements measured-As, Cd, Cu, Pb and Tl-reached levels either phytotoxic or toxic for humans or animals in seeds and the above-ground part of the spill-affected plants. We evaluate the potential use of sunflower plants for phytoremediation. The potential for phytoextraction is very low; however, it may be used for soil conservation. The production of oil (usable for industrial purposes) may add some value to this crop.

BACKGROUND: An alternative plan for saving scarce water could include use of non-conventional water resources such as reclaimed wastewater originating from wastewater treatment plants. The main health risks are associated with contamination of crops by wastewater due to its chemical composition. Therefore, the effect of recycled effluent irrigation was investigated on mineral composition and quality of olive oil of two local olive cultivars under field conditions during two complete cycles.

Excessive application of insecticides in agriculture has become an increasing trend in Thailand, where agriculture is common in the area. This problem leads to negative impacts on human health and environment. Therefore, this study focused on monitoring organophosphate and carbamate insecticides, and heavy metals (Cd, Cu, Pb, Ni, Hg, Zn and Mn) in Ipomoea aquatica Forssk, as well as water and soil from different canals in Ongkharak District, Nakhon Nayok Province, Thailand. The powder samples were prepared from roots, stems and leaves of Ipomoea aquatica Forssk, as well as soil. Then, anti-acetylcholinesterase activity of each sample was determined, and heavy metal contents were measured by atomic absorption spectrometry. The results showed that the highest anti-acetylcholinesterase activity was found in the soil samples, followed by those of leaves and stems, roots, and water, respectively. Additionally, the order of heavy metal concentration of stem and leaves, root, water and soil samples were Mn>Cu>Hg>Ni>Zn>Cd>Pb, Mn>Zn>Ni >Cu>Cd>Hg>Pb, Ni>Cu>Hg>Mn>Cd>Zn>Pb, and Mn>Cu>Ni>Zn>Pb>Cd>Hg, respectively. The concentration of Cu and Hg in stems and leaves were above the standard levels of Ministry of Public Health (2003), while Cu and Cd in root samples were above the standard levels. Additionally, the concentrations of Cd, Ni and Zn in all water samples were above the standard levels of Ministry of Natural Resources and Environment (1994), and the concentrations of Cu, Hg and Mn in certain water samples were above the standard levels. The translocation factors (TFroot and TFwater) and bioaccumulation factor (BAF) above 1 were observed in order of Cu>Ni>Cd>Zn>Mn, Mn>Zn>Ni >Cd, and Mn>Zn>Ni>Cd, respectively. The findings provide useful information to agricultural and public health authorities for a dialogue in policy development (i.e. the importation and use of pesticides) to minimize health risk of vulnerable population including farmers and nearby communities in the province, and thus strengthening equity in health.
