Abstract
This study evaluated the effects of municipal solid waste (MSW) char and compost amendments on alluvial soil over 120 days. Results showed improved soil properties with reduced bulk density by 12%, increased porosity by 14%, cation exchange capacity (CEC) by 6.14-fold, 11.3% increase in pH, soil organic matter (SOC) and soil organic carbon increased by 5.49 and 2.27-fold, respectively. Nutrient levels initially rose with higher amendment doses but declined over time, staying above control levels. Heavy metal availability was lower with the application of 1% MSW char alone, while the combined application of char with compost increased exchangeable metal bioavailability. A pot study with Okra showed reduced heavy metal uptake and improved plant growth compared to the control. Overall, the combined use of MSW char and compost boosts soil health and plant growth, while MSW char alone effectively reduces heavy metal availability in soil.
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.
