Heavy metal contamination of soil result from anthropogenic as well as natural activities. c) Strategies to immobilize Cd and decrease its availability in soil d) Phyto extraction of heavy metals (Cd): Agronomic management of the cocoa crop, Cocoa physiology, Cd bioaccumulation in cocoa beans. In vegetables farms where paper wastewater is used for cultivation of vegetable crops the vegetables the world health risks consumption. Heavy metals are dangerous in the form of their cations and are highly toxic when bonded to the short chains of carbon atoms (Kirmani et al., 2011). Toxicity of trace metals in soil as affected by soil type and aging after contamination: Using calibrated bioavailability models to set ecological soil standards. Briefly, 600 mg of air-dried soil was mixed with 6 mL of concentrated HNO 3 –HClO 4 (87:13, v/v) and 6 mL of concentrated HCl. Food safety is a major public health concern worldwide. Toxicol. Contaminants of volatile organic compounds. e) Growing and plantation areas, soil amendments and its cost efficiency, especially for small cocoa farmers, pruning, optimal time of harvest. The most common contaminants of heavy metal are Cd, Cr, Hg, Pb, Cu, Zn, and As. The mean concentration ± SE (standard error) of heavy metals in soil samples was highest for Pb and lowest for Hg in an ascending sequence of Hg < Tl < Cd < Ni < Cr < Pb (Table 5). Such standards were proposed for the five elements (mg/kg): copper – 3, nickel – 4, cobalt – 5, chromium – 6, zinc – 23. The FAO approach differs from most other land evaluation systems in three major aspects: While the former systems constituted often a direct follow up of soil surveys and soil inventory studies, becoming thus in the first place a soil survey interpretation, the FAO system started from the other end, i.e. Food Standards Australia and New Zealand Standard 1.4.1 – Contaminants and Natural Toxicants laid down maximum levels of FIVE heavy metals in specified food 9.
