and experience, but combine local wants and conditions into their insurance policies, legal guidelines and laws. There is comparatively good data regarding the allowable amounts of heavy metals that crops and soil can be exposed to when wastewater, sludge or biosolids are applied to soil (Page and Chang, 1994; UNHSP, 2008; WHO, 2006). Moreover, for each developed and growing countries, the content material of heavy metals in wastewater, excreta and sludge from domestic sources is usually low enough to allow their use for crop fertilization (Jiménez and Wang, 2006; UNHSP, 2008; WHO, 2006). However, there are always circumstances the place care needs to be taken, for example, near tanneries or mining areas (Abaidoo et al., 2009). The risk from natural parts derived via wastewater is generally a lot decrease than via direct pesticide utility. In comparison with pathogenic well being dangers, pesticide levels on greens, even if elevated, have been thought-about to be of secondary significance within the context of a developing nation (Amoah et al., 2006). In each developed and developing nations, sludge disposal is a matter growing in line with the increase within the volume of wastewater handled. Historically, sewage sludge has been considered to be waste that is to be disposed of at least possible cost . As a outcome, it has historically been dumped in landfills, holes, any unoccupied surface and drainage methods (Jiménez et al., 2004). However, faecal sludge, excreta and biosolids are increasingly being utilized on land in low- and middle-revenue nations due to the excessive price of contemporary landfills that meet all environmental requirements, the issue of finding appropriate websites for landfills and the benefit of recycling plant nutrients and enhancing soil traits. Their major use worldwide is to fertilize agricultural fields or green areas. This apply solves an issue for municipalities, helps farmers to decrease their organic and mineral fertilizer costs and preserves or improves soil fertility. Another necessary use of sludge is to enhance degraded soils at mining websites, construction sites and different disturbed areas . To complement the chemical and biological information collection, the study sought to know how farmers perceive environmental dangers. Not
