Abstract

The deposition of metallic substances on farmland is of critical importance owing to its possible detrimental impacts on the surroundings and human wellness. Heavy metals can adversely affect the physicochemical properties of soil and plant health. Prolonged exposure to heavy metals in humans can lead to both carcinogenic and non-carcinogenic effects. The present research intended to determine the dispersion condition of toxic metals on cropland and assess the attendant environmental and health dangers in the Wonosobo Regency. This study used a soil sample survey encompassing 312 soil sampling sites. The completed analyses comprise geographical analysis, index of geo-accumulation (IG), contamination index (CI), Nemerow comprehensive contamination index (NCCI), risk analysis, and health risk analysis. The research findings reveal that cadmium material is the primary contributor to contamination from heavy metals in farmland in Wonosobo Regency, as shown by IG analysis. The CI and environmental hazards assessments suggest considerable pollution levels. Kids are more prone to illnesses than adults due to their daily intake amount, so it is necessary to pay more attention to the daily intake sources in children to minimize exposure to heavy metals.

Abstract

The negative impact of excessive exposure to agrochemicals in shallot cultivation causes environmental pollution and human health. Biochar has the potential to absorb agrochemical contamination. This research aimed to investigate the effect of providing compost and biochar from agricultural waste on land quality, reducing the concentration of heavy metal cadmium (Cd) and mancozeb pesticide residues in soil and products in shallot. The experiment was carried out in shallot fields in Ngurensiti Village, Pati Regency, Central Java Province. Four different treatments, including combinations of biochar and compost, were applied, along with conventional controls. Data were analyzed using the F test (ANOVA) and Tukey's test using the Minitab statistical program version 16.0. The research showed that using biochar made from sugarcane bagasse, rice husk, corncob, and compost helped more soil bacteria grow and lowered Cd and mancozeb concentrations. In addition, treatment with biochar from sugarcane bagasse waste showed a decrease in Cd and mancozeb concentrations and a more significant increase in bacterial populations compared to other treatments (rice husk biochar and corncob biochar). Although there was a slight increase in Cd concentration in shallot leaves post-treatment, Cd levels in shallot bulbs remained within safe limits. This study shows that using biochar and compost from agricultural waste effectively improves soil quality, reduces heavy metal pollution, and lowers pesticide levels to support sustainable agriculture and protect people's health.

Abstract

Excessive pesticide use and intensive shallot farming to satisfy high market demand can degrade soil quality and harm environmental sustainability. Sustainable agricultural practices, such as biochar and compost are alternatives to ensure long-term soil productivity and fertility. This study aimed to investigate the ability of biochar and compost made from bagasse waste to improve shallot growth, yield, nutrient absorption, and soil quality. The research used a factorial randomized block design in a greenhouse. The first factor was the application of biochar and compost (K1 = compost, K2 = biochar, K3 = biochar-compost (1:4/w:w) and K4 = biochar-compost (1:2/w:w), and the second factor was the dose of NPK fertilizer (0%, 50%, and 100% of the recommended dose). The planting medium used was an Inceptisol from shallot fields in Sukaharjo, Central Java. The variables measured included plant growth, yield components, soil chemical properties, and levels of N, P, and K in plants. The results showed that the combination of compost with 100% NPK fertilizer gave better results in plant growth, fresh and dry weight of plants and tubers, increased organic C, total N, and CEC of the soil, and increased the absorption of N, P, and K by plants.

Abstract

Introduction: Pollution is a major factor contributing to the decline in river water quality, which serves as a source of clean water for residents. This study examines the pollution degrees of heavy metals, including lead, cadmium, chromium, nickel, arsenic, cobalt, and manganese, in surface water, as well as the associated public health risks for adults and children. Methods: Water samples were obtained from 18 unique sites along the Serayu River in Central Java Province. The concentrations of heavy metals were measured utilizing an Atomic Absorption Spectrophotometer. The heavy metal pollution index was employed to evaluate the Serayu River's suitability as drinking water. Public health risks were evaluated by employing the hazard quotient (HQ), hazard index (HI), and carcinogenic risk estimation. Results and Discussion: The heavy metal pollution index exceeded 100 at several sampling sites (W1, W2, W3, W4, W6, W7), indicating that the water is unsafe for drinking. However, non-carcinogenic risks from metal ingestion are negligible, as the HI and HQ values for both adults and children remain below one. The estimated carcinogenic risk is within the acceptable threshold (1E-4), with values of 1.109E-6 for adults and 4.199E-6 for children, suggesting no significant carcinogenic risk to the population. Conclusion: The results indicate that the Serayu River does not pose a significant carcinogenic or non-carcinogenic for illness to adults and children. However, owing to their heightened susceptibility to toxic effects, monitoring strategies to address the elevated vulnerability of children to heavy metal exposure

Abstract

Agriculture is a major contributor to non-point source pollution due to the intensive use of agrochemicals. This study examined the spatial distribution of pollutants from agricultural activities in the Sumani sub-catchment, West Sumatra, Indonesia, which drains into Lake Singkarak. Thirteen water quality parameters were measured, including electrical conductivity (EC), total suspended solids (TSS), total dissolved solids (TDS), dissolved oxygen (DO), sulfate, nitrate, calcium, sodium, total phosphorus (TP), potassium, magnesium, chlorpyrifos, and mancozeb. Results showed significant variation in water quality across the sampling sites. Downstream areas had higher levels of TSS, TDS, and major ions, mainly due to agricultural and urban activities. The lowest TSS levels were recorded at a site within the lake, likely due to sediment settling. River water generally met drinking water standards; however, TP and DO concentrations in the lake exceeded regulatory limits, potentially influenced by floating net cage aquaculture. Principal Component Analysis identified three main sources of pollution: agricultural activities (34.87%), combined agricultural and urban influences (20.15%), and soil erosion (12.15%). These findings highlight the need for better erosion control, sustainable farming practices, and consistent water quality monitoring. Further research is crucial to understand the long-term effects of agriculture on water resources and to develop strategies that reduce environmental impacts.

Abstract

Shallot cultivation usually uses very intensive agrochemicals that could affect the soil’s chemical properties and contaminate agricultural land by increasing the content of heavy metals. The use of agrochemicals is closely related to the behavior of farmers. The research aimed to study the heavy metal contamination and soil chemical properties in shallot fields and analyze the relationship between farmer behavior in using fertilizers and pesticides with a heavy metal concentration in agricultural land. The research was conducted in Srigading Village, Batul, Yogyakarta. Soil samples as many as 30 samples were taken from the shallot fields before harvest using a purposive sampling method and were analyzed for heavy metal concentrations of Pb, Cd, Ni, Co, Cr, and other soil chemical properties. Interviews were also conducted with landowners or farmers at the soil sampling location. Analysis of interview data was carried out by scoring each qualitative data into quantitative data through a questionnaire and testing the correlation between farmer behavior and heavy metal content. The results found that the shallot fields in the Srigading Village, Bantul contain heavy metals Pb, Cd, Cr, Co, and Ni with concentrations below soil quality standard. The soil organic carbon content in shallot fields has a low value. Farmer behavior has a weak negative correlation with heavy metal content in the soil.
