“…To assess the organic or inorganic pollution load in water, sediments play a critical role [ 32 ]. [ 33 ] determined heavy metal concentrations in water, sediments, and aquatic vegetation at Site Burley Griffen; they found sediments contained a higher concentration of heavy metal than water or aquatic plants. Our study also confirmed higher heavy metal concentrations in sediments ( Table 2 ) than in water ( Table 1 ).…”

The present study was conducted on Head Punjnad (HP) and Head Taunsa (HT) to evaluate the contamination of Pb, Cr, As, Hg, and Cd in water, soil, sediment, fish as a whole and fish organs. Fish, water, soil and sediment samples were collected from different sites of HT and HP on a monthly basis for 8 months. Heavy metals in water, soil, and sediment were determined by a polarized Zeeman atomic absorption spectrophotometer and in fish and fish organs by an atomic absorption spectrophotometer. Contamination of Cd, Hg, and As was significantly (P<0.05) higher in water of HP as compared to HT, while Cr showed a non-significant (P>0.05) difference at HP and HT. Pb was significantly (P<0.05) higher in water of HT as compared to HP. In the case of soil, Cd, Hg, and Pb were higher at HT as compared to HP, while As and Cr were significantly (P<0.05) higher at HP as compared to HT. In sediment, contamination of Cd, Hg, and As were significantly (P<0.05) higher at HP as compared to HT, while the Cr difference was non-significant (P>0.05) but Pb showed a significantly (P<0.05) higher value at HT than HP. Cd accumulation in different fish species was recorded as R. rita ˃O. niloticus ˃C. marulius ˃S. sarwari ˃C. idella ˃C. catla ˃N. notopterus ˃E. vacha ˃L. rohita ˃C. carpio, respectively.

The spatial legacy of Australian mercury contamination in the sediment of the Molonglo River

Introduction European colonies were first established in Australia in 1788. The discovery of gold and subsequent gold rushes in the 1850s brought migrants to the country and developed mining into a full-fledged industry (Blainey, 1993; Davies and Oliver, 2018). The prosperity of this industry formed an economic backbone of early European Australia, and the country enjoys the legacy of that prosperity to this day. Much of this mining industry, however, has also left a legacy of contamination. Given the lack of metal contamination control in these historical mines, a comprehensive environmental assessment is needed to comprehend the extent and nature of mining legacy impacts on ecosystems and communities across Australia. It is estimated that more than 50,000 legacy mines in the country require environmental assessments to avoid ongoing and future environmental issues (Pepper et al., 2014). Captains Flat, in New South Wales, is home to the Lake George Mine, a legacy mine site that predates the implementation of any environmental protection legislation in New South Wales (Zillig et al., 2015). The earliest relevant legislation in the state, the Mining Act 1992, was introduced 30 years after the mine closed (Zillig et al., 2015). Mining in Captains Flat originally sought gold, but later targeted galena, sphalerite, chalcopyrite and pyrite deposits in the orebody, seeking lead, zinc, copper and iron (Pryke, 1995). Hg amalgamation techniques in Captains Flat were used to extract gold, but the sulfide ores targeted in later mining were also known to contain Hg by-products (Pryke, 1995; Rytuba, 2003). These mining operations contaminated the Molonglo River, which feeds Lake Burley Griffin, an artificial lake in Canberra, the Australian capital. The lake was completed in 1963 after the Molonglo River was dammed (Caitcheon et al., 1988). The lake is located in the approximate geographic centre of the capital and is a popular location for many recreational uses; including swimming, rowing, fishing, and sailing. While Lake Burley Griffin has social and heritage importance, it is a focus of study here because it acts as a sink for sediment transported by the Molonglo River (Caitcheon et al., 1988). Previous studies have shown significant contamination of metals in both the Molonglo

“…For metals, a range of extraction procedures has been advocated, including the use of EDTA, dilute acid, or acid containing pepsin as a digestive enzyme (Maher et al 1992). The cold, dilute (1M) hydrochloric acid extraction that is used for AVS and SEM measurements (see below) is recommended (Simpson et al 1998).…”

Uncertainties in sediment quality assessments are discussed in five categories: (1) sediment sampling, transport and storage; (2) sediment chemistry; (3) ecotoxicology; (4) benthic community structure; and (5) data uncertainties and QA/QC. Three major exposure routes are considered: whole sediments, and waters in sediment pores and at the sediment-water interface. If these uncertainties are not recognized and addressed in the assessment process, then erroneous conclusions may result. Recommendations are provided for addressing the identified uncertainties in each of the key areas. The purpose of this paper is to improve the reporting of sediment quality assessments.
