This paper describes the model of heavy metal-Cu contaminated soil remediation standard value based on risk assessment. In the Cu contamination risk assessment model, the main exposure methods are oral ingestion and inhalation through breathing, which not only simplifies the calculation but also make people get a clearer understanding of the way of Cu contamination. We get the simplified formula, calculate and discuss Cu contaminated soil remediation target value in specific parameters to provide reference and basis for the remediation of Cu contaminated soil.

Selective sequential dissolution (SSD) and isotopic dilution are two most commonly applied techniques for the measurement of mobile fraction of heavy metal present in the urban environment. This work examined the compliance between SSD proposed by the Community Bureau of Reference (BCR) and isotopic dilution technique (IDT) for determination of mobile pool of heavy metal contained in soakaway sediment, road dust, and soil sample. Heavy metals (Cu, Zn, Cd and Pb) were fractionated using the three-stage BCR protocol, while isotopically exchangeable metal concentrations (E-value) were investigated through isotopic tracers (111Cd, 65Cu, 207Pb and 66Zn). In general, total contamination level, E-value and BCR exchangeable fractions of different samples followed the similar order of road dust > soakaway sediment > soil. Results revealed that the E-value exceeded the BCR exchangeable fraction in all samples. In addition, the first three fractions of BCR which have potential to become mobile under certain environmental conditions were collectively termed as “potential mobile pool” and compared with E-value. It was concluded that metal extracted by weak acid underestimates the exchangeable fraction while the potential mobile pool extracted by three reagents overestimates the real mobile forms of heavy metals. However, better mobility characteristics of heavy metals can be assessed by coupling information obtained through sequential extraction and isotopic exchange.

ABSTRACT The chemicals contained in an extract must be maintained its quality. The aim of this study is to prove both that the ethanol extract of kecapi (Sandoricum koetjape, Merr.) and keluwih (Artocarpus communis) leaves meet the non-specific parameters on the standardization of the extract. The ethanol extract of kecapi and keluwih leaves were extracted using the ultrasonic method. The extract was tested with non-specific parameters including water content, total ash content and metal contamination level. The test results are compared with standard parameter references. Ethanol extract of kecapi leaf have water content of 27.75% ± 1.708, total ash content of 4.856% ± 0.040 and levels of As metal contamination < 0.030 mg/Kg, Hg < 0.002 mg/Kg, Pb < 0.400 mg/Kg, while ethanol extract of keluwih leaf have water content of 23.206 ± 0.091%, total ash content of 9,678 ± 0.306% and levels of heavy metal contamination of As < 0.03 mg/Kg, Hg < 0.006 mg/Kg, Pb < 0.02 mg/Kg. The both extract meet the standard parameters of water content, total ash content and levels heavy metal contamination.

Low Levels

Human urine is by far the largest contributor of nutrients to household wastewater. Source separation of urine can significantly decrease the nutrient load on the recipients. By recycling the urine to agriculture as a fertiliser, with very low levels of heavy metals, the nutrients are made into resources instead of becoming pollutants. The amounts and concentrations of nutrients and heavy metals in urine solution from a source separating sewage system were measured. The concentrations of nutrients were high. The ratio of nitrogen to phosphorus was close to the expected value, indicating that the system did not have any large nitrogen loss. The heavy metal concentrations in the urine were low, much lower than that in most chemical fertilisers. Per inhabitant and day, 1.34 litres of urine solution were collected. Of this, 0.34 litres was flush water. The low flush water volume was due to the double flush mechanism of the toilets, which saved 48% of the flush water compared with conventional water closets. Per inhabitant and day, 4.9 g of nitrogen and 0.42 g of phosphorus were collected, which was 86 and 81% respectively of the expected amount. The contamination level of faecal material in the source separated urine was low.

Heavy metal contamination to Poyang Lake is increasingly severe. Bellamya aeruginosas, the dominant species of bellamya in Poyang Lake, was chosen in this project to carry out a proteomics study, because they obtain nutrients from sediments directly and have a strong heavy metal enrichment capability. To get a better knowledge of the contamination level of Poyang Lake and a better understanding of toxicity and bioavailability of heavy metals contamination, the main heavy metals of surface sediments were tested and a proteomics study was carried out on bellamya aeruginosa, the dominant species of bellamya in Poyang Lake. Results of heavy metal tests show, to Poyang Lake, the most contaminated heavy metal is Cu, the widest contaminated heavy metal is Pb, the most contaminated area is the south lake area, and the least contaminated area is the entrance of Xioushui River. Proteomics analysis shows the main significantly different proteins are keratins or similar substances. These proteins are higher expressed in the samples obtained from the most contaminated area, so they could be the responding biomarkers for monitoring heavy metal contamination of surface sediment in Poyang Lake.

Segara Anakan is a semi-close water ecosystem which is connected to Donan River (industrial and residential areas) in the east and Citanduy River (agricultural area) in the west. Most activity in those areas can produce a waste which becomes sources of harmful pollutants to the aquatic environment. The aim of this study was to analyze the content level of heavy metals (Pb, Hg, Cu and Cd) in muscle and safety level consumption of the tank goby (<em>Glossogobius giuris</em>) in the area. This study was conducted for 4 months in June, August, September and October 2017 at the waters of East Segara Anakan Lagoon of Cilacap (Central Java Province), The heavy metal concentration in the muscle was measured by AAS (Atomic Absorption Spectrophotometer). Based on the analysis, the heavy metal contents of Pb, Hg, Cu, and Cd in the tank goby were 0-0.005 mg/kg, 0-0.044 mg/kg, 0.164-0.293 mg/kg, and 0.001-0.032 mg/kg, respectively and these contents were under the safety limit. Safety level of consumption of the fish was 837.3  g/week (for adult) and 251.2  g/week (for children).<br /><br />

The potency and utilization of Lampung Bay has been recognized for their socio-economical and ecological values. However, heavy use of this Bay may alter the abundance of hazardous chemical like heavy metals. The aims of this study were to determine the concentration of Cd, Cu, Pb and Zn in the sediment and to assess Lampung Bay water condition. The observation of heavy metal content in sediment of Lampung Bay was conducted at 13 stations in March 2008. Analysis of heavy metals in sediment was conducted using three kinds of acid: HNO3, HCl and H2O2 while measurement was carried out by Atomic Absorption Spectrophotometer. The result indicated a variation of heavy metal concentration in sediment and that concentrations of Cd, Cu, Pb and Zn in sediment were 0.08 mg/kg dry weight, 22.99 mg/kg dry weight, 24.75 mg/kg dry weight and 118.48 mg/kg dry weight, respectively. Factors influenced heavy metal concentration in sediment in this study including the distance between sampling location and anthropogenic activities and the sediment fraction  SQG-Q index indicated that 7 stations have SQG-Q ≤ 0.1 whereas other 6 stations have 0.1≤ SQG-Q <1, meaning that more than half sampling stations are in uncontaminated state.
