The utilization of livestock waste has attracted increasing attention in recent years. The presence of high levels of heavy metals is a major obstacle to the utilization of biogas as a fertilizer resource. In this study, the heavy metal contents in biogas residue, slurry, and discharged sewage from three representative farms of gooseries, henneries, and dairy farms in the Yangtze River Basin were investigated and assessed. The results demonstrated that heavy metals, including Cd, Mn, As, Cu, Pb, Cr, Zn, etc., could be detected in all biogas residues, with significantly different contents between farm types (p < 0.005). Specifically, biogas residues from the goosery and the dairy farms met “China’s Organic Fertilizer Standards” (COF Standards); however, Cd concentrations in biogas residues from hennery farms exceeded the limits by five times. The concentrations of Cd and Pb in biogas slurries from all of the farms exceeded the limits of the “China Farmland Irrigation Water Quality Standard” (CFIWQ Standard). In particular, the Pb concentrations in biogas slurry from the dairy farms exceeded the limits by 29 times, and the discharged sewage from all three farm types complied with the comprehensive sewage discharge standards in China; however, only that from the goosery farms was suitable for irrigation. Thus, it is recommended to increase the feed selection, biogas engineering, and biological-purification-supporting technology, and to carry out regular sampling inspections of the biogas residue, slurry, and discharged sewage for heavy metals, so that environmental and crop pollution risks can be reduced when they are used as sources of nutrients for eco-friendly agriculture.

The continuous development of biogas engineering in recent years has been accompanied by an increasing number of biogas-residue types in the environment. The existence of various heavy metal elements in biogas residues, particularly excessive amounts of zinc and copper in pig farm biogas residues, hinders their safe utilisation. Several studies have focused on an effective composition for biogas residues or on their effects on soil and plants. However, few investigations regarding the removal of harmful substances from biogas residues have been conducted. The characteristics of heavy metals leached from pig farm biogas residues using eight types of leaching agents were analysed in this study. It is expected that, based on this study, different uses for biogas residues can be developed under the premise of security. The results showed that the most suitable extractant of heavy metals from pig farm biogas residues was EDTA2Na. The leaching rates increased over time. The leaching rates of copper and zinc after 2 h were 21.91% and 48.66%, respectively. After being leached for 2 h by EDTA-2Na, the concentration of zinc met the requirements for moderate alkaline soil, according to the Control Limits against Harmful Substances in Composts for Agricultural Use (DB44/T 361-2006) standard.

Sewage Sludge Compost

Sewage dump is the main organic waste component accumulating in water treatment companies, and therefore the utilization of dump remains a burning issue. Fertilization is the most popular and cheapest way of using sewage dump a part of which is intended for agriculture in most European countries for composting purposes. Sewage dump or its compost are suitable for fertilizing the upper layers of the soil in cases the concentration of heavy metals is not greater than sanitarian standards can tolerate. The examinations were carried out using different waste dump rates from Vilnius water treatment facility in willow (Salix viminalis) grown cultivated fields. The analysis of the soil was executed after one and two years following the fertilization process. The obtained results indicate that waste dump is a valuable organic fertilizer which contains small amounts of heavy metals. Separate heavy metals migrate from sewage sludge compost to plants differently. It was noted that the concentration of heavy metals in willows was greater (except for Pb and Cd) than that in the soil.

Kebutuhan bahan pangan sangat tergantung pada ketersediaanya di lingungan. Bahan pangan yang diperlukan untuk memenuhi kebutuhan sehari-hari harus sehat dan bebas dari bahan pencemar, termasuk logam berat. Ikan kakap putih (Lates calcarifer) sering dijumpai pada kawasan muara sungai di hampir seluruh wilayah Indonesia, bahkan di Papua. Tujuan penelitian ini adalah untuk mengkaji kandungan logam berat Pb, Cd, Cu, Fe, As, dan Hg pada ikan kakap putih (L. calcarifer) yang hidup di perairan estuari Mimika Papua. Perairan estuari di Mimika diketahui sebagai salah satu daerah pengendapan pasir sisa tambang (tailing). Metode yang digunakan adalah survei dan analisis laboratorium kandungan logam berat pada tubuh ikan. Analisis Pb, Cd, Cu, Fe, As, dan Hg ditentukan dengan spektroskopi serapan atom (AAS, Atomic Absorpsion Spectroscopy). Penentuan tingkat pencemaran logam berat dilakukan dengan Metode Standar APHA 3113 Cetac Technologies SPR IDA. Analisis data dilakukan dengan membandingkan kandungan logam berat dalam air dengan baku mutu air laut menurut SK MNLH No. 51 tahun 2004. Untuk kandungan logam berat pada organ tubuh ikan dibandingkan dengan kandungan maksimum logam berat berdasarkan SNI 7387: 2009 tentang batas maksimum cemaran logam berat bahan pangan. Kandungan logam berat pada ikan kakap putih masih tergolong aman dikonsumsi karena mengandung logam berat di bawah ambang batas baku mutu. Kondisi ini didukung oleh hasil analisis logam berat pada air yang menunjukkan masih dalam kondisi baik.   Kata kunci: L. calcarifer, logam berat, Sungai Kamora, Sungai Ajkwa, Mimika.   The need for food depends on the availability in the environment. Foods needed to meet daily needs should be healthy and free of pollutants, including heavy metals. White snapper (Lates calcarifer) is often found in the estuary of the river in almost all parts of Indonesia, even in Papua. The purpose of this research is to study the heavy metal content of Pb, Cd, Cu, Fe, As, and Hg on white snapper (L. calcarifer) which live in Mimika Papua estuary waters. The estuary waters of Mimika are known as one of the deposition areas of tailings sand. The method used is survey and laboratory analysis of heavy metal content in fish body. Analysis of Pb, Cd, Cu, Fe, and Hg was determined by Atomic Absorption Spectroscopy (AAS). Determination of the level of heavy metal contamination was done by Standard Method of APHA 3113 Cetac Technologies SPR IDA. Data analysis was done by comparing the heavy metal content in water with sea water quality standard according to SK MNLH No. 51 year 2004. For heavy metal content in fish body organs compared with maximum content of heavy metals based on SNI 7387: 2009 on the maximum limit of heavy metal food contamination. The content of heavy metals in white snapper is still considered safe for consumption because its below the quality standard threshold. This condition is supported by the results of heavy metal analysis on the water which shows still in good condition. Key words: L. calcarifer, heavy metal, Kamora River, Ajkwa River, Mimika.

Buriganga River

This work has been conducted to evaluate the water quality of the Buriganga river. In situ water quality parameters and water samples were collected from 10 locations in January 2016 and analyzed later in laboratory for water quality parameters such as pH, Eh, EC, TDS, cations (Na+, K+, Ca2+, Mg2, As3+), anions (Cl-, HCO3-, NO2-, NO3-, SO42-, F-, Br-, PO43-), heavy metals (Cr2+, Pb2+, Zn2+, Cd+2, Fe2+, Mn2+) to see whether or not the level of these parameters are within the permissible limits. The average values of pH, Eh, EC and temperature were 7.31, –214.9 mV, 928.9 μs/cm and 21.4°C, respectively; the average concentration of Na+, K+, Ca2+, Mg2+, and As3+ were 109.62, 13.38, 46.78, 13.98 and 0.018 mg/l, respectively, while the concentrations of Cl-,HCO3-, PO43-, SO42-, NO3-, NO2-, F and Br -were 79, 331.06, 2.22, 84.32, 0.0254, 0.058, 0.224 and 0.073 mg/l, respectively; and the concentration of heavy metals Pb2+, Zn2+, Fe2+ and Mn2+were 0.28, 0.053, 0.17 and 0.23 mg/l, respectively. The study indicates that most of the parameters are within the permissible limits set by Bangladesh water quality standard. The concentrations of K+, Mn2+, and Pb2+ were beyond the permissible limits meaning that that the water of Buriganga is not safe for drinking. The people living beside Buriganga river should be more cautious about using the polluted/contaminated river water. The concerned authorities should take urgent necessary steps to improve the degraded water quality of the river considering the ecological, environmental and economic implications associated with it.
