Cadmium, Copper, Lead, Nickel and Zinc Concentrations In Tomato and Squash Grown In MSW Compost-amended Calcareous Soil

Compost Use in Organic Farming

“…Incorporating a municipal-waste compost at 48 t ha −1 or a municipal-waste biosolids co-compost at 24 t ha −1 into a calcareous limestone soil increased concentrations of soil-extractable metals, but caused no significant changes in tomato and squash (Cucurbita pepo L.) fruit concentrations of Cu and Zn compared to an unamended control (Ozores-Hampton et al 1997).…”

Effect of wastewater and compost on leaching nutrients of soil column under basil cultivation

“…Despite the growing interest in wastewater and compost usage, excessive application of them may have some harmful effects such as human health problems, runoff and leaching of nutrients to surface and groundwater, undesirable chemical constituents, pathogens, accumulations of heavy metals in plants and soils, negative environmental and health impacts (Al-Nakshabandi et al, 1997;Ozores-Hampton and Hanlon, 1997;Friedel et al, 2000;Cooke et al, 2001;Qiang et al, 2004;Singh et al, 2009). So, wastewater and compost application should be under controlled conditions that minimize health risks of pathogenic and toxic pollution to agricultural products, soil, ground and surface water.…”

Heavy metal content of some common spices available in markets in the Kumasi metropolis of Ghana

“…The addition of spices that may be contaminated with trace and heavy metals to food as a habit may result in accumulation of these metals in human organs and lead to different health troubles (Al-Ed et al, 1997) These metals may reach and contaminate plants, vegetables, fruits and canned foods through air, water and soil during industrial processing and packaging (Ozores et al, 1997). The study of these heavy metals is crucial because they have potential hazardous effect, not only on compounds but human health as well.…”
