Abstract
This study investigates the impact of domestic sewage wastewater irrigation on the cultivation of cassava (Manihot esculenta Crantz) from selected agrofields of Palakkad, Kerala with a comparison of well-water-irrigated M. esculenta from the same area. For this, the physicochemical parameters of respective water and soil samples were analysed. Further, to understand the post-harvest crop quality which includes the peeled tuber, peel, leaf and stem proximate composition, and mineral contents including heavy metal composition and in vitro antioxidant potential. The results of the physicochemical parameters of both domestic sewage wastewater and well-water irrigated samples (both water and soil) were observed within the permissible limits according to the WHO/FAO suggested pattern. Interestingly, heavy metals such as Zn, Cd, Cr, Cu, and Ni were within the admissible limit in respective samples from both fields. In general, when compared with well-water irrigated cassava crop samples, the antioxidant potential was significantly higher (p < 0.05) in sewage wastewater irrigated cassava samples. The present study demonstrated that domestic sewage water was found to have promising physicochemical properties that allow for safe use for irrigation as liquid organic fertilizers and the cassava crop residues from such agrofields could also be exploited as potential animal feed.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
