Heavy Metals In Soils

This research was conducted in Tarus Village, Kupang regency, in May until June 2013, to find out the amount of phosphorus and cadmium content in the soil of rice, and to compare the Cd with a threshold concentration of Standard National Indonesia 7387:2009, as well as to predict the magnitude of the risk to the health. This research is descriptive experimental design with 12 samples of soil and rice. Levels of soil–available P is analyzed using the methods of Olsen, whereas, the levels of Cd from the soil and rice are analyzed in the laboratory with the method of analysis of heavy metals in soils and plants, set by Hall of geochemical soil, the Ministry of agriculture. The results of the analysis of land-available Pranging from low – high, but it is not the only deciding factor the amount of Cd in soil and rice. Laboratory analysis results towards rice Cd, shows there are six samples that undetectable levels of Cd, six other samples detected and then described the risk once compared with the standard quality raw and analysis of health risks. The results of the analysis of the levels of Cd shows all rice samples were still below standard quality raw i.e. 0,4 mg kg-1. Risk analysis indicates that there are two samples of rice produced from the paddy fields are not safe for consumption for the duration of 30 years. While the four other samples were a risk for the duration of the 60 years.

Abstract In this paper, the total and phytoavailable form of copper in allotment garden in Zielona Góra are presented. Soil samples were collected from eight places in the allotments gardens and two samples from outside in the neighbourhood. The total content of copper varied from 2.58 to 16.23 mg · kg-1. The form of copper potentially avail-able for plants varied from 0.2 to 3.85 mg · kg-1. The total content of copper meets the requirements of Directive by the Minister of Agriculture and Rural Development of the 21st March 2002 on the acceptable content of heavy metals in soils and Directive by the Minister of the Environment of the 9th September 2002 on the standards of soil quality and the standards of land quality

The Impact

Total 54 fertilizer samples were randomly collected from the markets of four districts ofBangladeshto assess nutrient and heavy metal (Cd, Cr & Pb) contents in different fertilizers. The chemical analyses of fertilizers were conducted at the Department of Agricultural Chemistry,BangladeshAgriculturalUniversity, Mymensingh. Nutrient status of fertilizers was determined using the standard procedures and heavy metals in the fertilizer extract were analyzed using Atomic Absorption Spectrophotometer (AAS). Nitrogen (N) content in urea collected from different areas ranged from 41.37 to 46.27%. Biuret content of the collected urea samples varied from 1.40 to 2.80%, where the maximum allowable limit (MAL) is 1.50%. Among the six urea samples, biuret content exceeded the MAL in five samples. Phosphorous (P) content in most of the triple superphosphate (TSP) samples was higher than the specified amount. Out of eight samples, only two samples contained less than 20% P. Out of eight diammonium phosphate (DAP) samples, only three samples contained lower amount of P than the specified amount and five samples contained lower amount of N than the specified amount. Chromium content in all theDAPsamples were much higher than the MAL. Potassium (K) content in all five collected muriate of potash (MoP) samples were lower than the specified amount with an average of 45.81% K. The concentration of sulphur (S) in fertilizer samples in the investigated area varied from 16.50 to 21.60%. Out of six magnesium sulphate samples, five samples contained lower than the specified amount (9.5%) of Mg. The concentration of boron (B) in solubor samples varied from 13.55 to 19.56%, which are lower than the standard limit (20.90%). The concentration of zinc (Zn) in all the collected zinc sulphate heptahydrate samples had lower amount of Zn than the standard limit (23%). Only one out of six collected copper sulphate samples, met the specified limit of Cu (25.40%). Total 42 fertilizer samples (77.80%), out of 54, had less than the specified amount of nutrients. Heavy metals like Pb and Cr content exceeded the MAL in 67% and 47% of collected fertilizer samples, respectively. Cadmium content was below the detectable limit of flame in AAS in all the samples. In order to minimize the impact of fertilizer adulteration on food security and safety, continuous monitoring of fertilizer quality is required.J. Bangladesh Agril.

Nafion-Ru(bpy)32+-Gold Nanoparticles (AuNPs) modified glassy carbon electrodes were fabricated and were used in detecting heavy metals in Philippine rice samples by differential pulse voltammetry (DPV). The said electrodes were fabricated via the drop coating technique. The concentrations of the modifiers, Ru(bpy)32+ and AuNPs, were varied to determine the best electrode for detecting lead, cadmium, and copper. Based on DPV results, the electrode with 5 mg Ru(bpy)32+ and 3 mg AuNPs was chosen as the best electrode. The calibration curves of the best electrode showed strong correlation values of 0.9984 for lead, 0.9905 for cadmium, and 0.9933 for copper. The limit of detection for lead, cadmium, and copper were 10 mg/L, 10 mg/L, and 200 mg/L, respectively. Atomic absorption spectrometry was used as a cross reference to verify the results from DPV. The lead and cadmium content of all the rice samples exceeded the World Health Organizaton (WHO) limit that the body can take. Some samples contained copper above the WHO limit.
